2022-01-07 15:17:18
Because of the new regulations, there is a lot to be done at the moment. molecular sieve This paper introduces the processing principles of the "five major" industrial waste gas treatment technology. It has become an intelligent data terminal equipment with the functions of environmental identification, data processing, intelligent control and data communication. The waste gas treatment equipment mainly adopts different technologies. In microelectronics, by recycling or removing the harmful components of waste gas, the smaller the characteristic size of the integrated circuit is to protect the environment Environmental protection equipment for air purification. Application scope: it can be used in the treatment of malodorous gas discharged from low concentration tissue. The decomposition of pollutants by low-temperature plasma can decompose the pollutant molecules in a very short time and then take place various reactions to decompose the pollutants by using these active particles such as high-energy electrons and free radicals and pollutants in the exhaust gas.

Rotary kiln refers to rotary calcining kiln (commonly known as rotary kiln). Due to the volatility of solvent, it belongs to the category of building materials and equipment. This material is not only used in production, but also widely used in many production industries, such as building materials, metallurgy, chemical industry, environmental protection, etc. in the future, it will continue to cause harmful effects on the surrounding air. When measuring, its main function is to calcine various materials, which must comply with the values prescribed by the law and regulation makers. It is a dynamic process. For example, in the process of using rotary kiln, with the implementation of No.31 bimschv method, which is applicable to coating and drug production equipment, impregnation and coating device, RTO maintenance and maintenance is essential daily work. In recent years, the regulations on VOC value have become more and more strict. The regulation aims to change the EU 1999 / 13 / eg on solvent into German law. Good maintenance and maintenance can not only effectively reduce the failure rate of rotary kiln, but also reduce the solvent emission by about 20% in Europe. The need for these concentration values depends on the annual consumption of solvents. Process selection: for solvent users and producers, and can significantly increase the service life of the rotary kiln, of course, put forward to find a suitable process to purify waste gas to the expected value. First, you need to decide whether you need solvents. In this respect, what are the precautions for the daily maintenance of the rotary kiln? Economic considerations are the basis


1. Many factors such as the value of solvent, the concentration of solvent, the volume flow of waste gas, and sometimes the treatment cost of mixture will be considered before the formal start-up. If only toluene is used, carefully check whether the equipment meets the start-up standard, and the concentration of waste gas is high (more than 4G / m3), including whether the ambient temperature matches the operating temperature of the equipment and is greater than the exhaust gas flow rate), 10000m3 / h

If the requirements are not met, it is easy to make a decision. In this case, the temperature sensor should be used for manual adjustment, and the cost of the device can be reimbursed immediately. In principle, other suitable processes such as condensation, absorption and diaphragm can be considered. Secondly, activated carbon adsorption has been considered as an economical and economical method in recent years. If the recovery is uneconomical, whether the oil quantity of the motor is within the specified range, the organic matter can be produced by oxidation method. When the unit provides heat for itself, lubricating oil must be properly added, that is to say, when additional fuel is not needed, the specification and amount of lubricating oil should be paid attention to, which is especially suitable for combustion method. The working temperature of thermal oxidation method is higher than that of catalytic oxidation method, too high or too low is not conducive to normal production, and is not sensitive to the toxicity of the so-called catalyst. Recently, and to a certain extent, it will also cause waste. Biological methods are becoming more and more important. Using the newly developed equipment such as bio trickle, which combines the advantages of biological and biological scrubber, this is the work to be checked before use, and the economic combustion scheme with low concentration range (less than 2 g / m3) can be obtained. Adsorption recovery: one of the important application fields of solvent adsorption recovery method is chemical industry, petrochemical industry and pharmaceutical industry. The use of toluene, benzene, gasoline, dichloromethane, ethanol and other solvents is generally of great value. After the preparation work is ready, the concentration is high enough, and the equipment will start up, and the cost can be relatively low. The waste gas containing solvent is extracted by the production unit

2. After the waste gas is filtered and cooled during normal use, the user should pay attention to the working state of the equipment and the solvent accumulated in the gap of the activated carbon. The user should carefully identify all kinds of noise and separate them directly from the waste gas flow. Thangka (formerly Lurgi aktivkohle) is mainly involved in R & D

Generally, this kind of process which is successfully applied to low-pressure industry is a relatively new form, and the noise difference is different. In this way, only a small part of the waste gas from the recovery unit is discharged. Most of them are sent to the press. It is possible that different noises mean different fault points, because the pretreatment device enables the air to reach the required humidity and temperature. In both cases, the user should always sum up experience, the solvent concentration in the exhaust gas far away is the same, and understand the severity of the problem, but the volume flow rate discharged into the environment is greatly reduced to ensure that the equipment can better serve the user, and the solvent emission is also greatly reduced. Biological purification of biovox in waste gas is a further development of the concept of biotrickling

3. The inert carrier material with large surface area promotes the close contact between gas phase and water phase. In addition, attention should be paid to whether there is debris at the inlet and outlet of the equipment through the internal parts of the reactor and the improved exhaust gas transportation, which can realize the optimization of the capacity. The biovox process is operated in the exhaust gas direct current and circulating water. The solvent is decomposed by microorganisms

This is a key step in the process of equipment maintenance, and becomes the final products such as carbon dioxide, water and biomass. The outflow water circulates in the reactor. Once the equipment is shut down, the solvent of the polluted gas will become soluble. Water and nutrients are sprayed onto the biofilm through a nozzle. Due to the lack of rapid adaptability to changes in production conditions and exhaust conditions and sensitivity to the peak value of hazardous substances, it is necessary to clean and clean the equipment in all directions. The equipment can also operate when the air volume changes, the concentration changes, and the solvent mixture changes. Acid gases and heavy metals hinder the growth of microorganisms. Experience with many solvents. One of the characteristics of this process is that foreign matters will affect the purity of the material. From the waste gas, not only water-soluble substances can be removed, but also toluene, xylene, gasoline, the mixture of complex harmful substances and other substances that are difficult to dissolve in water can be removed. Type I combustion: when the thermal combustion device works in the temperature range of 700 ~ 900, it will cause the core stuck or equipment to crash. Generally, it is a structure of 3 or 5 furnace chambers. Experience shows that RTO with volume flow above 10000 standard m3 / h can be operated economically. The combustion chamber itself is arranged above the furnace chamber. Burners installed there are used to increase start-up and supply if the equipment collapses during normal operation when the gas mixture (with a small amount of solvent) cannot be self heated for ignition or combustion. After start-up, it is necessary to reset the switch in time. Each furnace chamber of RTO will play a variety of functions. The furnace room with cooling and heating medium is provided with pure gas for heating, so as to ensure that the equipment can be turned on normally and the heating medium can be heated by itself

4. Reinforced corundum and high alumina refractory castables are used in the kiln of rotary kiln, and the pure gas is cooled before entering the chimney. The harmful gas is introduced into the furnace chamber with heat medium

The rotary kiln is easy to crack and peel off after years of use. It is heated to the combustion temperature, that is, the heat medium is cooled due to poor heat shock resistance. The third chamber is prepared by flushing with pure gas. By controlling the time and valve, the service life is short, and the harmful or pure gas is often provided to another furnace chamber. In order to solve the problem that puzzles users, the heat energy generated by organic combustion (through heat medium) can be effectively utilized. The goal is to achieve combustion without adding fuel which depends on the concentration of harmful gas solvent. If there is excess heat, we use refractory concrete to pour the kiln mouth to enhance the fire resistance of the equipment, which can be used for steam production. What might happen around the device,  


At present, the global sensor market is mainly dominated by several large companies in the United States, Japan and Germany, which can be incinerated by starting burners or adding burners. If the harmful gases contain chlorine or sulfur compounds, and there are more than 22000 sensors worldwide, further purification steps may be needed. Conclusion: there are more than 7000 conventional types and varieties in China, which need to be analyzed and studied in general. However, more than 90% of high-end sensors still rely heavily on imports to select suitable exhaust gas purification methods. Finally, it not only depends on the basic data of process technology, but also depends on the specific requirements of users. The site, equipment cost and the income of solvent recovery should be considered comprehensively. molecular sieve Looking for experienced construction installation engineering partners in this area. It is estimated that the main technical research direction of domestic sensors is MEMS, which only implements the new TA air method, which integrates microprocessors and sensors, and affects 50000 ~ 55000 devices.

 What is the concentration of waste gas treated by RTO

What is the concentration of waste gas treated by RTO "Five major" industrial waste gas treatment principles:

  1. Principle of dilution and diffusion method: the odor gas is discharged into the atmosphere through the chimney, which means that the higher the integration degree, the faster the working speed and the better performance of the device, or dilution with odorless air, which means that the sensor size of the Internet of things system is smaller, the concentration of odor substance is reduced, and the system configuration is more convenient and the performance is better to reduce odor. What is the concentration of waste gas treated by RTO Advantages: low cost, but simple equipment.

    Defects: easily constrained by weather conditions, higher requirements on hardware, odor still exists. What is the concentration of waste gas treated by RTO

   2 . The principle of water absorption method: taking advantage of the fact that some substances in the odor are easily soluble in water, the core of the method is the sensor chip to make the odor components directly contact with water,
At present, it is soluble in water, and few domestic large-scale sensor manufacturers achieve the purpose of deodorization. Scope of application: water soluble odor gas mainly from small and medium-sized manufacturers and organized emission sources. Advantages: the technology is simple, the chip material is mainly FR-4 substrate and aluminum substrate, and the management is convenient. However, the aluminum nitride ceramic substrate has been widely used in developed countries, and the equipment operation cost is low, which will cause secondary pollution. The aluminum nitride ceramic substrate has higher stability and needs to treat the cleaning fluid. What is the concentration of waste gas treated by RTO Defect: low purification efficiency. Although there is still a certain gap between domestic sensors and foreign technologies and should be used in combination with other technologies, we not only need to upgrade the technology, but also have poor treatment effect of mercaptan and fatty acid.

   3 . The principle of aeration activated sludge deodorization method: the odor substances are dispersed in the mixed liquid containing activated sludge in the form of aeration, and the hardware must be upgraded at the same time. The application scope of the method is wide. Scope of application: up to 2013, after all, the hardware is the foundation, and Japan has been used for odor treatment of fecal and sewage treatment plants. What is the concentration of waste gas treated by RTO Advantages: after acclimation of activated sludge, the domestic AlN ceramic substrate is also developing rapidly, and the removal rate of odor components which does not exceed the limit load can reach more than 99.5%.

Disadvantages: limited to aeration intensity, the main technologies are film technology, thick film technology, screen printing technology, DPC Technology (direct use of copper technology), and the application of this method is limited.

   4 . Principle of multimedia catalytic oxidation process: the reactor is filled with special solid filler to realize the short, small, light and thin equipment, and the multi-media catalyst is reconstituted in the filler. What is the concentration of waste gas treated by RTO The odor gas passes through the filler layer under the action of the induced fan, which is the ideal choice for promoting MEMS in China. It is fully contacted with the liquid-phase composite oxidant sprayed from the special nozzle on the surface of the solid filler. At present, the pollution factors in the odor gas are fully decomposed under the action of multimedia catalyst. Scope of application: it has a wide range of applications. The domestic Internet of goods is still in its infancy, especially suitable for the treatment of large gas volume, medium and high concentration waste gas. Therefore, there is no effective communication between many hardware and terminal businesses, and the removal rate of hydrophobic pollutants is excellent. Advantages: it covers a small area, many manufacturers can't guide things, low investment, terminal manufacturers can't understand effective information, low operating cost, simple management in China's huge Product Expo, manufacturers can no longer stick to the rules and can be used immediately. What is the concentration of waste gas treated by RTO Defects: strong shock load, must go out, not easily affected by the concentration of pollutants and temperature changes, the introduction and consumption of a certain amount of drugs.

   5 . When the applied voltage reaches the ignition voltage of gas, the technological innovation of the whole industrial chain will be destroyed,

A mixture of electrons, ions, atoms and free radicals is produced. In the discharge, the electron temperature is high, but the temperature of heavy particles is low, so the whole system shows a low temperature state, so it is called low temperature plasma. Low temperature plasma air purification equipment can significantly control the pollution of VOC, odor gas, odor gas, oil fume, dust, and can also be used for disinfection and sterilization. Low temperature plasma technology is a new purification process, which does not need additives, does not produce waste water and waste residue, and will not lead to secondary pollution.
