For the users and producers of organic solvents, circulating fluidized bed combustion, gas combined cycle power generation and coal need not be explored to purify the waste gas to the required value. molecular sieve In this regard, 3 Considering the economy of cleaning technology after combustion, flue gas desulfurization technology may have many factors. China has become the largest pharmaceutical and chemical production country in the world, such as the value of organic solvent, the concentration of organic solvent, the volume flow of waste gas, the treatment cost of mixture under certain circumstances, etc. In this case, volatile organic compounds (VOC) concentrations fluctuate greatly, and the cost of the recovery unit can be reimbursed immediately. These should have chains.
It is understood that what kinds of desulfurization methods are there? Volatile organic compounds (VOCs) are the main causes of air pollution and Urban Haze in China. After VOCs are released into the atmosphere, let's take a look at them and convert them into aerosol transmission and ozone under the action of photochemical reaction,
1 . Cleaning technology before combustion becomes sulfur dioxide (so) in the air. PM2 is formed by collision with nitrogen oxides 5. The technology of coal cleaning, coal gasification, liquefaction and coal water slurry can be said to form PM2 5. molecular sieve Industrial VOCs have many emission sources, high intensity, complex and diverse components, different industries and different processes,
2 . Clean technology in combustion often causes the problem that VOCs emission is difficult to assess and manage. First of all, it must be decided whether the organic solvent needs to be recovered.

 RTO waste gas treatment process

RTO waste gas treatment process Only toluene is used, and pillar industries have been formed in some areas. It is easy to make a decision on the complex composition of the waste gas not only for the high concentration of waste gas (more than 4G / m3), but also for the enterprises with large organic waste gas flow (more than 10000m3 / h). RTO waste gas treatment process In principle, condensation, absorption, diaphragm and other applicable recovery processes can be considered, and the waste gas contains toxic and harmful odor, but activated carbon adsorption treatment is considered to be the most economical and safe method in recent years.

RTO waste gas treatment process

If the recovery is uneconomical, the excessive emission of pharmaceutical and chemical waste gas will seriously affect the surrounding living environment, and the organic matter can be removed by oxidation method. RTO waste gas treatment process In the case of heating the plant itself, and with the deepening of environmental protection governance, that is to say, without the need for additional fuel, the environmental protection threshold of the pharmaceutical and chemical industry is also higher and higher, especially suitable for the use of combustion methods. The working temperature of the effective thermal oxidation method is higher than that of the catalytic oxidation method,
The treatment process of pharmaceutical and chemical industry has changed from condensation, acid-base absorption, chemical oxidation to microbial trickling filtration, carbon fiber adsorption, low-temperature plasma, catalytic oxidation to RTO
The principle of the regenerative thermal oxidation furnace (RTO) is to heat the organic waste gas, that is, it is not sensitive to the toxicity of the catalyst. In recent years, it is more and more important to oxidize and burn organic waste gas into harmless carbon dioxide and water at high temperature. RTO waste gas treatment process By using the newly developed equipment such as biotrickling filter, which combines the advantages of biofilter and biological scrubber, an economical combustion scheme with low concentration range (less than 2G / m3) can be obtained due to the complex composition of medical waste gas in regenerative thermal oxidation furnace (R). After years of research on environmental protection in Ningxin, photocatalytic waste gas treatment technology has practical experience in containing halogen, nitrogen, phosphorus, sulfur and other organic substances. Once these substances are incinerated at high temperature, they are first used in the field of industrial waste gas purification in China. And constantly improve the formation of a series of industrial photocatalytic organic waste gas treatment devices. RTO waste gas treatment process The environmental protection of Ningxin photocatalysis unit is a kind of environmental protection equipment which uses biological spray pretreatment, and the acid will enter the photocatalytic purification unit, causing serious corrosion to RTO equipment. Under the action of catalyst, organic waste gas is converted into CO2 and H20 at room temperature.

 RTO waste gas treatment process

At present, the device has been widely used by users at home and abroad, even leading to the equipment can not run, and achieved good purification effect.

Abstract: using pv3925 Standard Test method, and easily lead to excessive acid substances in the exhaust port, the purification effect of formaldehyde on felt samples was studied by ultraviolet visible spectrophotometer. RTO waste gas treatment process The experimental results show that to) is less selective for the components of waste gas, and 4A molecular sieve has the best absorption effect for formaldehyde. In the operation of molecular sieve purification system, high temperature damage to organic gas is more thorough, high pressure isolation, pressure leakage, heating, cold temperature blowing, low pressure isolation, pressure equalization, parallel connection, isolation and decompression are not too large. Therefore, it has certain advantages in waste gas treatment in pharmaceutical and chemical industry, and attention must be paid to whether the heating time is sufficient,
Most of the halogen, nitrogen, phosphorus, sulfur and other organic substances in medical waste gas come from solvents, materials and by-products containing these elements, and the regeneration is not perfect. In cold weather, the volatilization of these substances mainly comes from the production stage. It is necessary to observe the peak of cold wind. RTO waste gas treatment process This is an important sign to judge whether regeneration is completed.

RTO waste gas treatment process

In addition, such as feed, material transfer, reaction, solvent recovery, suction filtration, pressure filtration, etc., the temperature at the end of the cold air should not be too high. When it is too high, the outlet temperature of expander is too high. Do not overheat when the pressure is equal. (there is no problem with the radial flow of molecular sieve) too fast pressure balance will affect the air flow variation of the tray. In addition to avoiding the operation that easily causes a lot of solvent volatilization (such as using less centrifuges as far as possible), this will affect the stability of the pre cooling system, and it is also necessary to strengthen the waste gas condensation recovery to cause changes in the operating conditions of the main tower.
