Embodiment 1

[0029] like figure 1 , figure 2The shown bag-type dust removal device includes a box body 1 with a closed chamber. The bag-type dust removal device in this embodiment is two symmetrically distributed boxes 1, and the shown box body 1 is provided with an air inlet 2. , the airtight chamber is provided with an ash hopper 3, a filter bag 4 and an exhaust manifold 5 from bottom to top, and a negative pressure fan 6 is arranged on the exhaust manifold 5; between the ash hopper 3 and the filter bag 4 There is also a first rotating baffle device 71 and a second rotating baffle device 72 arranged oppositely. The rotating baffle device 7 includes a driving device and a baffle. The driving device is installed on the inner wall of the box body 1. One end of the plate is connected to the drive device and the drive device drives the shutter to rotate around the connection point. The dust-laden gas enters the airtight chamber through the air inlet 2. First, the large particles of dust fa...

Embodiment 2

[0036] A method of using a bag-type dust removal device, comprising the following steps:

[0037] S1: After closing all valves, turn on the negative pressure fan 6 for a period of time, so that the box 1 is in a negative pressure state;

[0038] S2: Open the air inlet valve 20, so that the dust-laden gas enters the gas processing chamber; start the driving device to drive the rotating baffle device 7 to rotate; remove the dust in the dust-laden gas;

[0039] S3: Set the pressure difference value when too much dust affects the flow of gas through the filter bag 4 as the first preset pressure difference value, and the pressure difference value at which dust removal work can be started is the second preset pressure difference value; turn on the fan automatically Control switch, when the pressure sensor 12 detects that the pressure difference between the clean air chamber and the outside of the box 1 increases to the first preset pressure difference value, close the air inlet valv...

Abstract

The invention relates to a dust removal device, in particular to a bag type dust removal device and a using method thereof. The bag type dust removal device comprises a box with a closed cavity, wherein an air inlet is formed in the box; an ash hopper, a filter bag and an exhaust header pipe are respectively arranged in the closed cavity from bottom to top, and a negative pressure fan is arranged on the exhaust header pipe; a rotary baffle device is further arranged between the dust hopper and the filter bag, the rotary baffle device comprises a driving device and a baffle, the driving device is mounted on the inner wall of the box body, one end of the baffle is connected with the driving device, and the driving device drives the baffle to rotate around a connecting point. The invention provides a bag type dust removal device capable of efficiently removing small-particle-size dust.

Description

technical field [0001] The invention relates to a dust removal device, in particular to a bag type dust removal device and a method for using the same. Background technique [0002] The bag type dust removal equipment is a high-efficiency dust collector. When the dust-containing gas enters the bag type dust removal device, the dust with large particles and specific gravity will sink into the ash hopper under the action of gravity, and the gas containing small particle size dust will When passing through the filter bag, the dust is blocked by the filter bag to obtain purified gas. The bag-type dust removal device in the prior art, such as the patent with the announcement number "CN201470241U", discloses a sonic bag dust removal device, the gas containing finer dust directly passes through the filter bag from the air inlet, and the removal efficiency of small particle size dust needs to be improved . The invention provides a bag-type dedusting device for efficiently removing...
