A dust removal device and method for efficiently cleaning filters

Abstract

The invention discloses a high-efficiency cleaning filter dust removal device and method, comprising a purge chamber, a water spray treatment chamber connected with the purge chamber and located below the purge chamber; the purge chamber is provided with a filter for fixing the filter The filter bag holder of the bag, and the top of the purge chamber has a tiltable cover plate, and the cover plate is equipped with uniformly arranged high-pressure purge nozzles; the side of the water spray treatment chamber is equipped with an atomizer for forming a water spray effect The nozzle; also includes a water retaining chamber, the water retaining chamber communicates with the water spray treatment chamber and is located at one side of the water spray treatment chamber. The invention has a simple process principle, simple processing and production process, and is suitable for on-site operation due to small site restrictions. The use of high-pressure purge and dry cleaning avoids soaking the filter bag, reduces damage to the filter material, prolongs the service life of the filter, and saves maintenance. cost. In addition, the dust particles are purged in a fully sealed state to avoid environmental pollution, and the use of water spray greatly saves water resources and plays a role in environmental protection.

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
