It can be used for purification treatment of exhaust solvents (benzene, alcohol, ketone, aldehyde, chisel, phenol, ether, alkane and other mixed waste gas), wire, electric unity, enameled wire, machinery, motors, chemical, instrumentation, automobiles, bicycles, motorcycles, engines, tapes, plastics, household appliances and other industries in the exhaust gas purification, can be used for a variety of baking channels, printing iron canning, surface spraying, printing inks, motor insulation treatment, shoe gluing and other baking in the pipeline, purification of waste gas generated by various processes. Medium concentration (usually concentration between 2000-5000 mg/m³) of organic waste gas in the chemical agent (group, platinum, put and other precious metals) under the action of low-temperature oxidation flameless combustion, the organic components oxidized to CO₂ and H₂O products, catalytic combustion method features: no flame combustion is easy to control, the combustion control temperature is relatively low between 125-300°C, plus less consumption of heat energy, different components of the waste gas must be different exhaust gas components must choose different forms of catalysts and the process of burning. The gas entering the catalytic combustion device must be washed and preheated, so that the temperature of the exhaust gas reaches the ignition temperature of the catalyst (between 220-250°C), remove dust particles, liquid droplets, and other catalytic inhibitors, to avoid the blockage of the catalytic bed and the poisoning of the catalyst failure. Equipment features: easy to operate, equipment work, realize automatic control. Low energy consumption: catalytic combustion air using honeycomb ceramic as the carrier of the precious metal catalyst, low resistance, high activity.
When the concentration of exhaust vapor reaches 2000ppm or more, it can maintain spontaneous combustion.
Safe and reliable: the equipment is equipped with a positive fire to remove the sitting system, explosion-proof pressure relief system, over-temperature alarm system and advanced self-control system of low resistance, high purification rate using today's advanced capital metal honeycomb ceramic carrier catalysts, large specific surface area.
Waste heat can be reused: waste heat can be returned to the baking channel, reducing the original baking channel's power consumption, and can also be used as a heat source for other aspects of only 70% ~ 80% of similar products in the industry 6. and no special requirements for the foundation of the equipment.
Small footprint: long service life: catalyst is generally replaced more than 8000 hours, and the carrier can be renewable.
Process and principle: The process mainly adopts high-efficiency catalyst, the exhaust gas oxidation reaction occurs under the action of catalyst, generating non-toxic and tasteless carbon dioxide (CO2) and water (H2O):

Its unique high-efficiency heat exchanger system ensures the effective recovery of waste heat. When the concentration of exhaust gas reaches a certain level, the heat exchanger system enables the organic exhaust gas to be heated up to the starting temperature of catalytic oxidation reaction without electric heating, and treats the organic exhaust gas through its own heat balance. The device is the organic waste gas into the main equipment, through the role of the catalyst decomposition into water and carbon dioxide, while releasing energy can be replaced by the heat exchange device energy for the maintenance of equipment self-ignition energy. Amount, when the catalytic bed temperature reaches 250~3000 when the catalytic combustion bed began to react, the use of exhaust gas combustion generated by the hot air cycle, at this time the electric heating stops, no external heating, the internal loading of ceramic honeycomb body capital metal catalyst service life of 8000 small the entire desorption system using multi-point temperature control, to ensure that the effect of desorption of the stability of the system. When
The principle of the process “catalytic combustion method” is to heat the exhaust gas to the ignition temperature, in the role of the catalyst for flame-free combustion, generating carbon dioxide and water and releasing a large amount of heat. Catalytic combustion purification device according to the catalytic combustion mechanism, by the optimization room, electric heating box, heat exchanger, fan. Electric control cabinet is composed of five major parts.
When the exhaust gas enters the device first to the heat exchanger. With catalytic combustion after residual heat through the heat exchanger to raise the temperature of organic waste gas as much as possible usually temperature △ 1 = 50 ~ 60C, and then sent to the electric heating box, through the electric heating tube heated to the temperature of the start of the combustion, generally in 200 ~ 250C. to reach the temperature will automatically shut down the heating system, which then enters the catalytic box, catalytic combustion reaction, so that the oxidation of the CO and HC decomposition of carbon dioxide and water and the release of a large amount of heat. release a large amount of heat. At this time, when the exhaust gas concentration of a certain amount of waste heat generated through the heat exchanger after the temperature rise has reached the ignition temperature, then the catalytic combustion device to reach a dynamic thermal balance, which saves a lot of electrical and thermal power, the above process can be fully automated through the PLC system control cabinet work.
