Thermal storage catalytic combustion equipment

Steps for using the thermal storage catalytic combustion equipment

Generally coated on the carrier, so its shape varies according to the carrier. There are spheres, cylinders and various shaped bodies made of γ-Al2O3, porous ceramic honeycomb bodies covered with activated alumina film on the surface of the carrier, expanded balls made of heat-resistant alloy wires, corrugated metal plates, etc. The carrier can reduce the amount of catalyst, which can be used as a support. The carrier can reduce the amount of catalyst and play a supporting role. It should have the characteristics of large specific surface area,, high mechanical strength and low fluid resistance.

Regenerative catalytic combustion equipment: Firstly, it passes through the dust and fire stopping system. Then it enters the heat exchanger, and then sent to the heating chamber, so that the gas reaches the combustion reaction temperature, and then through the role of catalytic bed, so that the exhaust gas decomposition into carbon dioxide and water, and then into the heat exchanger and the low-temperature gas heat exchange, so that the temperature of the incoming gas rises to reach the reaction temperature. If the reaction temperature is not reached, the heating system section achieves the compensation heating through the self-control system. The use of catalyst as an intermediate, so that the gas at a lower temperature, into the water and carbon dioxide gas, that is: product performance characteristics: ① easy to operate, the equipment works, to achieve automatic control, . ② equipment start-up, only 15 to 30 minutes to warm up to the ignition temperature, low energy consumption. ③ Using today's precious metal palladium-platinum impregnated honeycomb carrier catalyst, large specific surface area, low resistance, . ④Waste heat can be returned to the baking channel to reduce the power consumption in the original baking channel; it can also be used as heat source in other areas. ⑤ Long service life, the catalyst is generally replaced in two years, and the carrier can be . Scope of application

1 Benzene, alcohols, aldehydes, esters, phenols, ethers, alkanes and other mixed exhaust gas treatment.

2 Suitable for exhaust gas purification in chemical, plastic, rubber, pharmaceutical, printing, pesticide, shoe-making and other industries.

Advantages Edit: It can reduce the starting combustion temperature of exhaust gas. For example, methanol, formaldehyde in the alumina carrier Pt catalyst (Pt/Al2O3) under the action of the room temperature will begin to burn, and direct combustion method is usually the beginning of the combustion point of 300 ~ 600 ℃. The combustion is not limited by the concentration of hydrocarbons. Basically, it does not cause secondary pollution. The equipment is simpler, less investment and faster. The main problem of catalytic combustion method is that the catalyst is easy to be poisoned and not. The substances that are easy to poison the catalyst are tar, soot, dust, lead compounds and compounds of sulphur, phosphorus and halogenated elements. In order to maintain the activity of the catalyst, generally use the pre-treatment method to get rid of toxic substances in advance.

From 1949, the United States developed the last set of catalytic combustion device to the present, this technology has been widely used in paint, rubber processing, plastics processing, resin processing, leather processing, food industry and foundry industry and other sectors, also used in automotive exhaust gas purification and other aspects. China in 1973 began to catalytic combustion method for the treatment of enamelled wire drying furnace exhaust, followed by insulation materials, printing industry and other aspects of the research, so that the catalytic combustion method has been widely used.
