Vertical dust remover

Abstract

The invention relates to a dust remover, and particularly relates to a wet and dry combined dust remover. The dust remover comprises a primary filter and a gas distributing disc 3, wherein the primary filter is positioned at the gas inlet; the gas distributing disc is positioned on the bottom of the dust remover; a bent channel is arranged above the gas distribution disc and comprises a first turning part, a second turning part and a third turning part; a centrifugal fan is arranged above the bent channel; the inner wall of the dust remover below the centrifugal fan is provided with a dust collecting groove; an HEPA filter screen is arranged above the centrifugal fan; a gas outlet is formed above the HEPA filter screen; the dust remover is internally provided with a particle concentration detector. The dust remover has the characteristics of high integration, low energy consumption and operation flexibility.

Description

technical field [0001] The invention relates to a dust removal device, in particular to a wet and dry combined dust removal device. It can remove ultra-fine dust particles in the dusty gas, and is especially suitable for dedusting the dusty gas, especially the fine dust gas. Background technique [0002] With the continuous enhancement of people's awareness of environmental protection, the requirements for the purification of dusty gas generated in the production process are also continuously improved. At present, most of the traditional bag filter (collecting dust particles with a diameter larger than 10 μm) or filter element filter (collecting dust particles with a diameter larger than 5 μm) is used to filter the dusty gas, and then directly discharged, the discharged gas still accounts for about 100% of the total amount. About 5% of ultra-fine dust particles with a diameter of less than 5 μm cannot be removed, and these ultra-fine dust particles directly pollute the envi...

AI Technical Summary

Problems solved by technology

At present, most of the traditional bag filter (collecting dust particles with a diameter larger than 10 μm) or filter element filter (collecting dust particles with a diameter larger than 5 μm) is used to filter the dusty gas, and then directly discharged, the discharged gas still accounts for about 100% of the total amount. About 5% of ultra-fine dust particles with a diameter of less than 5 μm cannot be removed, and these ultra-fine dust particles directly pollute the environment

Moreover, the disadvantages of the bag filter are also obvious. For example, the filter bag needs to be replaced frequently, and the life of the filter bag is also short. Especially under high temperature, corrosive environment and other working conditions, the filter bag is replaced more frequently, and the operating cost and Maintenance costs are more expensive

Another common dust removal method is wet dust removal, which uses spray to absorb liquid, and the liquid is in contact with dusty gas to achieve the purpose of absorption and purification. The disadvantages of wet dust removal are also obvious, such as the ability to absorb fine dust particles. Therefore, there is an urgent need in the market for a dust collector that can remove ultrafine dust particles with a diameter of less than 5 μm and relatively low energy consumption.
