Description

Technical Field

[0001] The utility model relates to the technical field of induced draft fans, and particularly relates to a smoke-eliminating, dust-removing and filtering induced draft fan. Background Art

[0002] An induced draft fan is a mechanical device for transporting gases, which is widely used in industrial, commercial and residential buildings to provide functions such as ventilation, exhaust, heating, cooling, air conditioning and air purification. The induced draft fan generates wind pressure through the rotation of its impeller, and promotes the flow of air, thereby realizing the transportation and discharge of gases.

[0003] However, the existing induced draft fans still have certain defects in smoke elimination and dust reduction. For example, they simply filter the soot and dust in the waste gas through a filter screen, and the smoke elimination and dust reduction effect is poor; secondly, after long-term use of the filter screen, a large amount of soot and dust will adhere to it, resulting in the blockage of the filter screen, which in turn affects the filtering effect of the induced draft fan. Moreover, the filter screen is usually welded inside the induced draft fan and is difficult to replace after being damaged, so the practicability is poor. Summary of the Utility Model

[0004] The purpose of the utility model is to at least solve one of the technical problems existing in the prior art, and provide a smoke-eliminating, dust-removing and filtering induced draft fan.
