Description

A catalytic combustion device with exhaust gas purification function

Technical Field

The utility model relates to the technical field of catalytic combustion equipment, in particular to catalytic combustion equipment with the function of purifying waste gas.

Background Art

Catalytic combustion is a purification method that uses a catalyst to oxidize and decompose combustible substances in exhaust gas at a lower temperature. Therefore, catalytic combustion is also called catalytic chemical conversion. Since the catalyst accelerates the process of oxidation and decomposition, most hydrocarbons can be completely oxidized by the catalyst within the temperature necessary for the reaction. Compared with thermal combustion, catalytic combustion requires less auxiliary fuel and has low energy consumption. For example, VOCs are toxic organic waste gases. Direct emission will cause air pollution. Therefore, they need to be purified before emission. CO can be decomposed into CO2 and H2O using CO as a catalyst. During the use of traditional catalytic combustion equipment, the exhaust gas will be directly passed through the intake pipe into the combustion tank, so that the exhaust gas will contact the catalyst and continue to burn.

However, during the use of traditional catalytic combustion equipment, the exhaust gas directly enters the combustion tank through the intake pipe. Because the exhaust gas contains slag, a large amount of particles and substances are burned, so the exhaust gas cannot fully contact the catalyst, which greatly reduces the exhaust gas treatment efficiency. Therefore, a catalytic combustion equipment with the function of purifying exhaust gas is proposed.
