Description

Dust remover

Technical Field

This patent relates to a dust remover.

Background

In recent years, with rapid development of economy, industrial air pollutants are harmful to the surrounding environment, and therefore, a technology for removing particulate matters from dust-containing gas to reduce the emission of the dust-containing gas to the atmosphere is becoming more and more important.

The dust-containing industrial waste gas is generated from mechanical processes such as crushing, screening, conveying and blasting of solid substances, or from processes such as combustion, high-temperature melting and chemical reaction. The former contains dust with large particle size and chemical composition the same as the original solid matter, and the latter contains dust with small particle size and chemical property different from that of the substance to be generated. Improvements in production processes and combustion techniques can reduce particulate generation. Dust collectors are widely used to control dust and fumes that have been generated.

The trapping mechanism can be classified into a mechanical dust collector, an electric dust collector, a filtering dust collector, a washing dust collector and the like. The mechanical dust remover removes dust particles from the airflow by means of mechanical force, and has the advantages of simple structure, low equipment cost and operation cost, but low dust removal efficiency. The electrostatic precipitator utilizes electrostatic force to separate dust particles from air flow, and is usually classified according to plate type and tube type, and is characterized by small air flow resistance, high dust removal efficiency up to more than 99%, but high investment. The occupied area is large. The filter dust collector enables dust-containing gas to flow through the filter material to separate and collect dust particles, and adopts two modes of internal filtering and surface filtering, so that the dust collection efficiency is generally 90-99%, and the filter dust collector is not suitable for dust-containing gas with high temperature. The washing dust remover washes dust-containing gas by liquid, so that dust particles collide with liquid drops or liquid films to be captured and are separated from gas flow, the dust removal efficiency is 80-95%, and the operation cost is high. In order to improve the efficiency of trapping particles, new dust collectors integrating several dust removal mechanisms, such as a charged bag filter, a charged droplet scrubber, and the like, are being developed. However, the dust removing equipment on the market can only remove particles with the particle size of more than 5 microns, and has poor dust removing effect and great pollution to air.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a dust remover which is characterized in that the dust remover comprises an air inlet pipe 1, a bin body 2, a filter bag 3, an induced draft pipe 4, an induced draft fan 5 and an air outlet 6;

the filter bag 3 is positioned in the bin body 2, and the lower part of the bin body is provided with a dust outlet 7; the air inlet pipe 1 is positioned at one end of the bin body 2, and the induced draft pipe 4 is positioned at the other end of the bin body 2;

the induced draft pipe 4 is connected with the air outlet 6 through an induced draft fan 5;

the filter bag 3 is of a multilayer structure and sequentially comprises a glass fiber base filter layer 3-1, a carbon tube reinforced polyacrylonitrile/nylon 6 composite fiber membrane layer 3-2, a PVDF electrospun fiber membrane layer 3-3 and a PET filter membrane layer 3-4 from inside to outside.

The thickness of the glass fiber basic filter layer 3-1 is larger than that of the carbon tube reinforced polyacrylonitrile/nylon 6 composite fiber membrane layer 3-2, and the thicknesses of the PVDF electrospun fiber membrane layer 3-3 and the PET filter membrane layer 3-4 are consistent.

The thickness of the PET filtering membrane layer 3-4 is larger than that of the carbon tube reinforced polyacrylonitrile/nylon 6 composite fiber membrane layer 3-2 and the PVDF electrospun fiber membrane layer 3-3.

And a rotating speed belt 10 is arranged on the induced draft fan 5.

The dust remover is provided with a frame 8, and the number of the frame 8 is 2-4, which are respectively positioned at the periphery of the bin body 2.

Has the advantages that:

1. the device has simple structure and convenient use, and can effectively reduce pollution emission;

2. when the flue gas is filtered, the dust and the ultrafine dust need to be filtered at the same time, the filtering effect of the product on the current market on the ultrafine powder is very low, so that the filtering effect on the flue gas is influenced, the environmental pollution is serious, the filtered gas is environment-friendly, and the dust can be effectively removed and the denitration can be effectively realized;

3. the equipment adopts the self-developed filter bag, and is very effective for filtering dust, so that the filtering effect of 0.01 micron dust reaches 97-99%, and the filtering effect of 0.01 micron dust of the filter bag on the market is less than 95%.
