Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to an explosion-proof waste gas treatment device. Background Art

[0002] Waste gas treatment refers to the process of collecting, purifying and treating waste gas generated in industrial production, energy utilization and other activities. Its main purpose is to reduce or eliminate the impact of waste gas on the environment and human health. Waste gas treatment equipment is needed to treat waste gas.

[0003] Some exhaust gas treatment devices currently on the market: for example, the utility model patent with authorization announcement number CN220495966U discloses an explosion-proof exhaust gas treatment device, which is equipped with a microwave photocatalytic device in the exhaust gas treatment box, an electronic control unit in the electronic control box, a heat dissipation vent on the top of the electronic control box, a nitrogen outlet pipe at the bottom of the electronic control box, and a nitrogen outlet pipe also installed in the exhaust gas treatment box. This can effectively reduce the operating temperature of the electronic control equipment and reduce the guaranteed lower limit of the exhaust gas treatment space. However, since the device lacks a mechanism for filtering particulate matter in the exhaust gas, particulate matter may block some channels of the microwave photocatalytic device, reducing the overall filtration efficiency of the device, and particulate matter will accumulate inside the device, affecting the adsorption and catalytic effect of the photocatalyst on harmful gases, which needs to be improved.

[0004] Therefore, we propose an explosion-proof exhaust gas treatment device to solve the above problems. Utility Model Content
