Problems solved by technology

[0003] The existing double-filter granular bed dust collector, after a long time of use, powder or dust is collected on the filter material, which needs to be blown off by back blowing to ensure the subsequent filtering effect. The blowing device can blow off the powder or dust on the filter material. In industrial applications, due to the large area of ​​the filter layer, it is impossible to absorb the retained powder or dust evenly on the filter layer. Relatively uniform fluidization, the longer the time, the greater the degree of fluidization unevenness, so that the powder or dust of the upper filter material cannot be blown off well, and there will be residues, making the backflushing effect not good

Embodiment 1

[0033] Such as figure 1 As shown in -2, the present invention provides a gas filter and dust removal device, comprising a housing 1 and a filter device 2 disposed in the housing 1. The filter device 2 is provided with multiple and arranged along the height direction of the housing 1. In this embodiment, the filter There are three devices 2 and they are evenly spaced along the height direction of the shell 1. Of course, the number of filter devices is different according to the different use environments. The shell 1 is provided with an air inlet 11 and an air outlet, and the air inlet 11 There is an air intake pipe 111 integrally formed with the shell 1, the air intake pipe 111 is in the shape of a cone with a small top and a large bottom, the bottom of the shell 1 is provided with a dust outlet 12, the inside of the shell 1 is provided with a dust collection channel 13, and a filter device 2 Including a first filter layer 21 and a second filter layer 22, the first filter laye...

Embodiment 2

[0049] The difference between this embodiment and the first embodiment lies in that the pressurization layer is different.

[0050] Such as figure 2 As shown, in this embodiment, the pressurized layer includes a pressurized air intake pipe 29 extending into the channel 271, a pressurized air intake 28 is arranged on the pressurized air intake pipe 29, and the pressurized air intake 28 faces the first filter layer 21. There are multiple supercharging air inlets 28 and they are evenly distributed on the supercharging air intake pipe 29 .

[0051] The benefit of this embodiment is that, by setting the pressurized air intake pipe extending into the passage, and setting the pressurized air intake on the pressurized air intake pipe, the reverse air can be better blown to the first filter layer, so that The first filter layer can better obtain the blowback pressure, which further increases the blowback volume of the first filter layer to ensure that the powder or dust on the first ...

Embodiment 3

[0053] The difference between this embodiment and the first embodiment lies in that the pressurization layer is different.

[0054] Such as Figure 4 , 5 As shown, in this embodiment, the pressurized layer includes a channel 271. The channel 271 is in the shape of a small cone with a small top and a large bottom. The channel 271 is provided with a first connection port that communicates with the first filter layer 21 and communicates with the second filter layer 22. The area of ​​the first connection port is smaller than the area of ​​the second connection port, and the filtration area of ​​the first filter layer 21 is equal to the area of ​​the first connection port.

[0055] The advantage of this embodiment is that the pressurized layer includes a channel, the channel is provided with a first connection port communicated with the first filter layer and a second connection port communicated with the second filter layer, and the area of ​​the first connection port is smaller ...

Abstract

The invention provides a gas filtration and dust removal device which comprises a shell and a filtering device arranged inside the shell. The filtering device comprises a first filtering layer and a second filtering layer. The first filtering layer is located above the second filtering layer. The bottom of the filtering device is provided with a reverse blowing gas inlet, and a pressurizing layer for enhancing reverse blowing wind pressure of the first filtering layer is arranged between the first filtering layer and the second filtering layer. Due to the fact that the pressurizing layer for enhancing the reverse blowing wind pressure of the first filtering layer is arranged between the first filtering layer and the second filtering layer, the first filtering layer can obtain the good reverse flowing wind pressure during reverse blowing, the reverse blowing wind capacity of the first filtering layer is increased, and it is ensured that dust on the first filtering layer can be removed completely so as to improve the filtering effect and the filtering efficiency.

Description

technical field [0001] The invention relates to the technical field of gas filtration and dust removal, in particular to a coal and chemical flue gas filtration and dust removal device. Background technique [0002] In the field of dust removal technology, double-filter granular bed dust removal has unique technical advantages. The filter adopts two kinds of coarse and fine filter materials placed in the same filter bed. The coarse filter material layer is on the top and the fine filter material layer is on the bottom. In order to achieve a good filter dust removal effect. [0003] The existing double-filter granular bed dust collector, after a long period of use, powder or dust on the filter material needs to be blown off by back blowing to ensure the subsequent filtering effect. The blowing device can blow off the powder or dust on the filter material. In industrial applications, due to the large area of ​​the filter layer, it is impossible to absorb the retained powder o...
