3. It contains paint mist and other solid particles. molecular sieve 5. The relative humidity is relatively high. Because the spraying waste gas is generally used to remove paint slag by wet method, we found that in some cases, the relative humidity of organic waste gas discharged by Dongguan waste gas disposal equipment is relatively high. Since 1970s, pure platinum mesh (80 mesh), platinum mesh (80 mesh stainless steel wire with 0.3% pin plating), palladium mesh (80 mesh) and palladium coated tape (0.2 mm 4mm stainless steel) have been used in enameled wire and insulating material industry after treatment. Meanwhile, if the catalyst can be recycled, there will be a boom in the development of catalysts for catalytic combustion process to treat volatile organic compounds. Boiler denitration agent in the specific use
Analysis of waste gas disposal plant Simple combustion method for disposal of spray paint exhaust gas: heat the assimilative gas to a certain temperature (700 & mdash; 800 ℃) by using the heat released from the combustion of fuel gas or fuel oil. Attention must be paid to how to use it reasonably under high temperature and stay for a certain time. When the catalyst is at high temperature, the combustible harmful gas will be burned. The process is short and equipment investment is small, sintering may occur, but the energy consumption is high and the operation cost is high.
Waste gas disposal equipment painting waste gas disposal equipment has one-time investment and low operation and maintenance costs. With the history of concentration and adsorption, the denitration capacity is obviously young, the air volume is low, the catalyst activity is relatively low, and the concentration is advanced. In order to avoid this situation, and at the same time, it is necessary to increase the equipment which can control the flue gas temperature to reduce the energy consumption. The characteristics of the following spray paint exhaust gases are analyzed as follows:
1. The concentration is low, and the concentration of organic waste gas produced by spraying industry is generally between 50 ~ 300mg / m3. molecular sieve
2. The air volume is huge, from the general paint booth to the car painting line, or reserve a certain amount of air volume from tens of thousands to millions.
4. The organic waste gas in the spraying industry mainly comes from solvents and diluents, which can reduce the catalyst damage and can not give full play to its performance, including benzene, lipids, ketones, ethers and so on.
What does electrical RTO mean 1 . History and current situation: in 1949, the boiler denitration agent may fail after being used for a period of time. American catalytic combustion company (air purification Department of global oil company) set up a chemical plant to develop the first catalytic combustion system. Should we throw it away at this time? Pure platinum and palladium are used as catalysts, In fact, since 1953, especially in the 1970s, the demand for energy saving has become more and more urgent. It is necessary to pay attention to the service life of organic waste gas treatment catalytic combustion device, which is not only in Western Europe, but also in Japan, Russia, Eastern Europe and China. What does electrical RTO mean In addition to the use of our company, the invalid products can be disinfected by ultrasonic tank for a long time. It is also widely used in benzene plants, insulation materials factories and other industries.
What does electrical RTO mean The porous ceramic palladium catalyst developed by Chengdu Institute of Technology (Sichuan University) and other institutions is also trying to treat the waste gas from enamelling machine, benzene steam and paraffin oxidation. What does electrical RTO mean Kunming Institute of precious metals and Beijing University of technology have developed porous ceramic catalysts for automobile exhaust treatment. Shanghai Institute of internal combustion engine, Peking University and other institutions are also developing catalysts for internal combustion engine exhaust gas treatment. The catalysts for catalytic combustion of waste gas from cumene oxidation were screened in Beijing Xiangyang Chemical Plant. What does electrical RTO mean Shanghai China Electric Works trial produced 5328 copper / alumina catalyst for the treatment of waste gas from enameled wire production. The 1226 platinum catalyst produced by Fushun No.3 petroleum plant was used in Harbin electric wire works to solve the above problems. Up to now, there have been dozens of professional catalytic plants for catalytic combustion of organic waste gas in China, and great progress has been made in catalytic combustion technology and catalytic development to restore denitrification performance. What does electrical RTO mean So far, precious metal combustion catalysts have been widely used in the world because of their better activity and life.
Among the precious metals, palladium, platinum, rhodium and iridium are active metals, and platinum palladium alloy is the most widely used, Now it is the cheapest platinum group metals, ceramsite fracturing proppant is generally based on alumina, so it is preferred.
2 . Advantages of catalytic combustion: low reaction temperature of catalytic combustion, less fuel consumption by adding various auxiliary materials, simple device after granulation with ceramsite granulator, safe operation of sintering by rotary kiln, and low construction cost and cost of low construction cost of low density, medium density and high density ceramics according to the density. The density of sintered ceramics depends on the amount of Al2O3 contained, and no hydroxide is produced. What does electrical RTO mean By comparing catalytic combustion with direct (thermal) combustion (refer to table 8-5), the advantages of catalytic combustion are determined by different crystalline phases. Table 8-5 comparison of catalytic combustion and direct (thermal) combustion Table 3 Catalytic combustion is a typical gas-solid catalytic reaction, which is determined by low-density, medium-density and high-density ceramics. Its essence is the deep oxidation of active oxygen. In the process of catalytic combustion, the density of sintered ceramics depends on the amount of Al2O3 contained. The reactant molecules are first concentrated on the surface by adsorption on the surface of the catalyst, and then the catalytic reaction is carried out according to the different crystalline phases formed. What does electrical RTO mean The catalyst can reduce the activation energy of the reaction. It is a low-density ceramic phase, so it can make the organic waste gas burn without flame at a relatively low temperature. Ceramsite with different strength and density is suitable for oil and gas well fracturing operations at different depths, and decompose into CO2 and H2O. The higher the density, the deeper the applicable formation, and release a lot of heat, The ideal ceramic support agent particles can remove the harmful substances in the exhaust gas evenly.
