Lvquan high quality Catalytic combustion is a purification method that uses a catalyst to oxidize and decompose combustible substances in exhaust gas at lower temperatures. So, catalytic combustion is also known as catalytic chemical conversion. Due to the catalyst accelerating the process of oxidation and decomposition, most hydrocarbons can be completely oxidized through the catalyst at temperatures ranging from 300 to 450 ℃.
Introduction to catalytic combustion equipment or devices: A catalytic combustion device refers to a device or device that burns under the action of a catalyst. The working principle of a catalytic combustion device is to use a catalyst to perform flameless combustion of organic waste gas at a lower ignition temperature, causing the organic waste gas to decompose into non-toxic carbon dioxide and water vapor. The catalytic burner electrical control system consists of PLC controller, text display, variable frequency speed controller, igniter, ultraviolet sensor, thermocouple and other electrical control equipment, as well as fan. In addition, the proportion of gas and air is adjusted by zero pressure valve. The entry also provides examples of HC type series organic gas catalytic combustion devices and LF-VC type direct catalytic decomposition oxidation devices, as well as unsafe factors and management measures in the use of catalytic combustion devices.
Catalytic combustion process
The method of using catalysts to reduce combustion temperature and accelerate the complete oxidation of toxic and harmful gases during chemical reactions is called catalytic combustion. Due to the fact that the carrier of the catalyst is made of porous materials with a large specific surface area and suitable pore size, when organic gases heated to 300-450 ℃ pass through the catalytic layer, oxygen and organic gases are adsorbed on the catalyst surface of the porous material, increasing the chances of contact and collision between oxygen and organic gases, improving activity, and causing violent chemical reactions between organic gases and oxygen to generate CO2 and H2O, while generating heat, thereby making organic gases non-toxic and harmless gases.
The catalytic combustion device mainly consists of a heat exchanger, combustion chamber, catalytic reactor, heat recovery system, and exhaust chimney for purifying flue gas, as shown in the right figure. The purification principle is that before entering the combustion chamber, the raw gas is preheated by a heat exchanger and sent to the combustion chamber. It reaches the required reaction temperature in the combustion chamber, and the oxidation reaction is carried out in the catalytic reactor. After purification, the flue gas releases some heat through the heat exchanger and is then discharged into the atmosphere through the chimney.

Regenerative Catalytic Oxidition is an organic waste gas treatment equipment that combines low-temperature catalytic oxidation with heat storage technology. It is an environmental protection equipment used to treat medium and high concentration organic waste gas purification. RCO regenerative catalytic combustion equipment is developed on the basis of RTO regenerative incineration equipment. A layer of catalyst is arranged on the thermal storage ceramic layer of the thermal storage equipment, so that the incoming waste gas is catalytically burned at 200℃-400℃ and decomposed into carbon dioxide and water, thereby achieving the purpose of purifying the waste gas.
Regenerative thermal oxidizers (RTO) are machines equipped with ceramic mass regenerative heat exchangers which allow for a high thermal efficiency thanks to their capability of quickly accumulating and yielding heat. This characteristic of theirs makes it possible to implement plants which yield up to 96%.
Regenerative Thermal Oxidizer,The principle of RTO regenerative incineration technology is to heat organic waste gas to above 760 ℃, so that VOCs in the waste gas are oxidized and decomposed into carbon dioxide and water. The high-temperature gas generated by oxidation flows through a specially designed ceramic heat storage body, causing the ceramic body to heat up and "store heat", which is used to preheat the organic waste gas that enters later.
