The commonly used methods for treating waste gas by the waste gas treatment device include adsorption method, absorption method, catalytic combustion method, thermal combustion method, etc.

[0003] The casting waste gas treatment devices currently available on the market have the following problems in actual use:

[0004] 1. When the traditional foundry waste gas treatment device is actually used, due to the fact that during the waste gas treatment process, when a large amount of waste gas flows into the foundry waste gas treatment device, when the waste gas passes through and reaches the filter element, it may cause varying degrees of blockage at the filter element, thereby affecting the waste gas treatment efficiency;

[0005] 2. During the use of most foundry waste gas treatment devices, it is necessary to connect them with pipes to introduce waste gas into the foundry waste gas treatment devices through the pipes. At this time, the waste gas may leak through the gaps when passing through the pipes and the installation site of the foundry waste gas treatment devices, and the sealing is poor during use.
