Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a waste gas catalytic combustion device. Background Art

[0002] Catalytic combustion is a typical gas-solid phase catalytic reaction, the essence of which is deep oxidation involving active oxygen. In the catalytic combustion equipment process, the role of the catalyst is to reduce the activation energy. At the same time, the catalyst surface has an adsorption effect, which causes the reactant molecules to be enriched on the surface, increasing the reaction rate and accelerating the reaction. With the help of catalyst catalytic combustion equipment, organic waste gas can be flamelessly burned at a lower ignition temperature, and oxidized and decomposed into carbon dioxide and water, while releasing a large amount of heat energy, thereby achieving a method of removing harmful substances from the exhaust gas. When the exhaust gas filter components of the existing catalytic combustion equipment are replaced, the catalytic combustion equipment also needs to be suspended at the same time, reducing the working efficiency of the catalytic combustion equipment.

[0003] Therefore, there is an urgent need for a waste gas catalytic combustion device to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings, the present invention aims to provide a technical solution that can solve the above-mentioned problems.

[0005] The specific plan is as follows: A catalytic combustion device for exhaust gas, comprising a combustion component and an exhaust gas filter component, a pipe body 1 being provided between the exhaust gas filter component and the combustion component, wherein the exhaust gas filter component comprises a box body and two groups of filters installed in the box body for filtering air impurities, the box body is provided with an upper cavity and a lower cavity, an air inlet is provided at the top of the upper cavity; and an air suction mechanism is installed in the upper cavity; mounting positions for filters are symmetrically provided on both sides of the lower cavity, the air inlets of the two groups of filters are connected to the upper cavity through pipe body 1; the air outlets of the two groups of filters are connected to the combustion component through pipe body 2.

[0006] Furthermore, the installation position is provided with a hollow portion corresponding to its height, width and length, and the hollow portion is provided with a detachable fixing plate, and the fixing plate is screwed to the box body.

[0007] Furthermore, the suction mechanism includes a suction fan and a motor for driving the suction fan, the motor is fixedly mounted on the top of the lower cavity, and its power end passes through the top of the lower cavity and extends into the upper cavity; the suction fan is located directly below the air inlet, and the suction fan is fixedly connected to the power end of the motor.

[0008] Furthermore, both the first tube body and the second tube body are provided with a first air intake control valve for controlling the gas output.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] The present application improves the box structure in the exhaust gas filter assembly by designing the box into the form of upper and lower cavities, with two installation positions for filters provided in the lower cavity, and an air suction mechanism provided in the upper cavity. The air suction machine can generate negative pressure through the rotation of the impeller, sucking the surrounding air into the upper cavity, and accelerating the entry of air into the interior of the combustion equipment through the two filters in the lower cavity. Because the air suction mechanism is not directly connected to the filter, the two filters can operate independently during the entire working process. When workers replace any filter, there is no need to suspend the combustion device, thereby ensuring the working efficiency and stability of the catalytic combustion equipment.
