Dust removal device and method of efficient cleaning filter

Abstract

The invention discloses a dust removal device and method of an efficient cleaning filter. The dust removal device comprises a blowing bin and a water spray treatment bin communicated with the blowingbin and located below the blowing bin; a filter bag support for fixing a filter bag of a filter is arranged in the blowing bin, a liftable cover plate is arranged at the top of the blowing bin, and high-pressure blowing nozzles are uniformly arranged on the cover plate; an atomizing nozzle for forming a water spray effect is arranged on the side surface of the water spray treatment bin; the dust removal device also comprises a water retaining bin communicated with the water spray treatment bin and located on one side of the water spray treatment bin. The dust removal device is simple in process principle, simple in processing and production process, small in field limitation and suitable for field operation, soaking of the filter bag is avoided due to adoption of high-pressure blowing, thedamage to a filter material is reduced, the service cycle of the filter is prolonged, and the maintenance cost is saved. Besides, dust particles are blown in a full-sealed state, environmental pollution is avoided, the water resource is greatly saved through water spray, and green and environmental protection roles are played.

Description

technical field [0001] The invention relates to the technical field of filter cleaning, in particular to a dust removal device and method for cleaning filters with high efficiency. Background technique [0002] The air-conditioning systems of office buildings and large shops generally adopt central air-conditioning and centralized air supply systems. The bag filters in the system are mainly used to block particulate dust, thereby reducing the air supply resistance of the air-conditioning system and reducing the air-conditioning load, but the filters are prone to contamination. Saturated with dust particles, frequent replacement of the filter actually makes the air conditioner run at a low resistance load, saving a lot of electricity bills. However, frequent replacement of filters will lead to higher maintenance costs, which is also a concern of the owner. [0003] There are two main ways to clean the filter bag: wet method and dry method: the wet method is washing with wate...

AI Technical Summary

Problems solved by technology

[0005] 1. Washing and soaking with water is easy to damage the filter bag. In order to maintain the effectiveness of the filter material of the filter bag, washing with water and soaking is only allowed to be cleaned twice at most, and a new filter needs to be replaced, which increases the cost of materials.

[0006] 2. It is easy to raise dust by blowing and washing with an exhaust fan, which will cause environmental pollution on site

[0007] 3. During the cleaning process, the filter bag needs to be rinsed repeatedly with clean water, which consumes a lot of water

[0008] 4. Due to site restrictions, it needs to be transported away from the construction site
