Embodiment 1

[0037] like figure 1 The back blowing soot cleaning system shown is used for the cleaning treatment of the tubular filter assembly. The tubular filter assembly includes an orifice plate 2 and six tubular filters 1. The tube Type filter 1 is firmly connected with the orifice plate 2 through the ring 13 protruding from the upper end; The six blowing pipes 41 and the six back-blowing and dust-cleaning devices corresponding to the six tubular filters 1 one-to-one.

[0038] like Figure 2-4 As shown, each back blowing soot cleaning device is used for back blowing soot cleaning of the corresponding tubular filter 1, and the tubular filter 1 includes an external filter membrane 11, an internal filter for supporting the filter membrane 11 A support frame 12 and an air outlet channel formed in the support frame 12; the back blowing dust removal device includes a back blow pipe 3 that matches the length of the tubular filter 1 in the air outlet channel, and the back blow The blowpipe...

Embodiment 2

[0049] like Figure 5 As shown, on the basis of Embodiment 1, the size of the inner end of the air outlet hole 320 in this embodiment is smaller than the size of the outer end. Under the same cleaning thickness, the back blowing pressure required in this embodiment is smaller and the cleaning is more comprehensive, especially for local locations such as corners, which can also be effectively cleaned.

Embodiment 3

[0051] like Image 6 As shown, on the basis of Embodiment 1, the air outlet holes 320 of two adjacent air outlet units 32 of this embodiment are arranged at intervals. Under the same backflushing pressure, the dust removal in this embodiment is more comprehensive.

Abstract

The invention discloses a backflow ash removal device. The blowback ash removal device is used for the backflow ash removal of a tubular filter, the tubular filter comprises an external filter membrane, an internal supporting frame for supporting the filter membrane and an air outlet channel formed in the supporting frame, the blowback ash removal device comprises a backflow tube located in the air outlet channel and matching with the length of the tubular filter, the backflow tube comprises a tube body, an air inlet located on the tube body and an air outlet structure for conducting the air inlet with the air outlet channel; and the air outlet structure comprises air outlet holes. The backflow ash removal device has the advantages of uniformity in the upper and lower force bearing of the filter membrane, good ash removal effect, difficulty in damage to the filter membrane, small noises generated in the use process, no damping, and no affection on the filtering efficiency.

Description

technical field [0001] The invention relates to the field of back blowing and dust removal, in particular to a back blowing and dust removal device and a back blowing and dust removal system. Background technique [0002] Tubular filter is a common filtering device, which usually includes an external filter medium, an internal support frame for supporting the filter medium, and an air outlet channel formed in the support frame. On the outside of the filter, the clean gas filtered by the filter medium is discharged from the air outlet channel, while the solid particles intercepted by the filter medium are attached to the outside of the tubular filter. For a filter assembly composed of multiple tubular filters, an orifice plate is used to connect the gas outlet of each tubular filter to the corresponding hole. Because these solid particles will block the pores of the filter medium, the air flux of the filter medium will be significantly reduced, resulting in a significant inc...
