Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically a waste gas treatment structure for an incinerator. Background Technology

[0002] Using incinerators to incinerate waste is a common waste disposal method today. However, incinerating waste in incinerators also produces waste gas containing pollutants. Therefore, waste gas treatment devices are needed to further treat the waste gas produced after the waste is incinerated.

[0003] When existing incinerators process waste, some small pieces of waste are not fully burned in the exhaust gas, and they are discharged simultaneously with the exhaust gas. This results in the incineration of this part of the waste not being fully burned inside the incinerator, leading to poor incineration treatment of this part of the waste. At the same time, when this part of the small waste undergoes heat exchange through the heat exchange components of the exhaust gas treatment device, a small portion of it will also adhere to the outside of the heat exchange pipes, affecting the heat exchange effect and making it difficult to filter and reprocess the unburned small waste.
