Technical Field

[0001] This utility model relates to the field of environmental protection technology, specifically to a dust removal device for exhaust gas from a waste incinerator. Background Technology

[0002] In recent years, with the improvement of people's living standards, the amount of urban domestic waste generated has increased rapidly, and the amount of waste accumulated over the years is huge. Generally, landfill is used to dispose of the waste, but this causes a lot of land to be eroded by the waste, resulting in the land becoming polluted and unusable. Later, incineration was adopted. Incineration can achieve the most effective treatment of domestic waste and occupies less land resources.

[0003] Existing waste incinerators still have some problems in use: the smoke from the incinerated waste is discharged directly from the chimney without filtration, so the exhaust gas enters the atmosphere directly, causing serious air pollution and failing to meet the needs of use. In addition, after the existing treatment equipment is connected to the waste incinerator, there may be flue gas leakage due to insufficient sealing. Utility Model Content

[0004] To address the issue that after incineration, the fumes are directly discharged from the chimney without filtration, causing severe air pollution and failing to meet usage requirements, and that existing treatment devices may leak fumes due to insufficient sealing after being connected to the waste incinerator; the purpose of this invention is to provide a tail gas dust removal device for waste incinerators.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a flue gas dust removal device for a waste incinerator, including a flue pipe, a connecting pipe fixedly provided on the lower surface of the flue pipe, a flange fixedly sleeved on the outer surface of the connecting pipe, a sealing assembly connected to the flange, and a filter dust removal assembly connected to the flue pipe.
