Problems solved by technology

[0003] The main reasons for the low efficiency of the cyclone separator are as follows: (1) The rotation rate of the cyclone separator is constant, and the centrifugal force generated by the particles in the dust-laden gas is also constant; (2) There is a short-circuit flow in the cyclone separator. , and there is a problem of secondary backflow of dust particles in the lower part

[0034] Please combine Figure 1-Figure 2 , the embodiment of the present invention provides an anti-backmixing cyclone dust removal device 100, which includes an outer separation shell 110 and an inner separation assembly 120. The outer separation shell 110 is provided with an air inlet 111, a bottom dust outlet 112 and a top outlet. Air tube 113 , inner separation assembly 120 is located in the inner cavity of outer separation housing 110 .

[0035] It should be pointed out that in the embodiment of the present invention, by setting the outer separation shell 110 and the inner separation assembly 120, the cooperation of the two can effectively reduce the back-mixing of the particles to be separated and improve the separation efficiency of the whole device.

[0036] Further, the outer separation housing 110 includes a top barrel body 114 and a tapered portion 115, the air inlet 111 and the top outlet pipe 113 are located on the top barrel body 114, the top wall of the tapered ...

[0048] Please refer to Figure 4 , the cyclone dust removal device 200 provided by the embodiment of the present invention has the same realization principle and technical effects as the first embodiment. For a brief description, for the parts not mentioned in this embodiment, you can refer to the corresponding content in the first embodiment . The difference from the first embodiment is that the cyclone dust removal device 200 provided by this embodiment has a better separation effect, and the particles in the dust-containing gas are effectively separated through multiple separations.

[0049] Further, the inner separation assembly 120 also includes at least one second separation piece 126, the second separation piece 126 is located in the inner cavity of the first separation piece 125, the top of the second separation piece 126 is open, and has a ring shape surrounding the top opening. Side wall, the position of the top of the annular side wall of the second separating part...

Abstract

The invention provides an anti-back-mixing cyclone dust removal device and a cyclone dust removal system, and relates to the technical field of dust removal equipment. The cyclone dust removal devicecomprises an outer separation shell and an inner separation assembly, the outer separation shell is provided with an air inlet, a bottom dust outlet and a top air outlet pipe, and the inner separationassembly is located in an inner cavity of the outer separation shell. The inner separation assembly comprises a first separation piece with an open top and an annular side wall enclosing the open top, the position of the top of the annular side wall is lower than the air inlet of the outer separation shell, and a first annular dust outlet channel is formed between the inner wall of the outer separation shell and the first separation piece. A first air flow channel is formed in an inner cavity of the annular side wall on the first separation piece, the bottom of the first separation piece is provided with an inner side dust outlet, and the bottom end of the top air outlet pipe is located in the first air flow channel. The cyclone dust removal system comprises the anti-back-mixing cyclone dust removal device, so that dust in gas can be well removed, the dust removal efficiency is high, and the back-mixing probability is low.

Description

technical field [0001] The invention relates to the technical field of dust removal equipment, in particular to an anti-backmixing cyclone dust removal device and a cyclone dust removal system. Background technique [0002] The cyclone separator uses the rotation of the gas to generate centrifugal force, so that it can separate the particles with different densities from the gas. It is a commonly used industrial dust removal equipment. The current cyclone separator is mainly single-stage, and the efficiency is low, generally lower than 92%. [0003] The main reasons for the low efficiency of the cyclone separator are as follows: (1) The rotation rate of the cyclone separator is constant, and the centrifugal force generated by the particles in the dust-laden gas is also constant; (2) There is a short-circuit flow in the cyclone separator. , and there is a problem of secondary backflow of dust particles in the lower part. [0004] In view of this, propose this application. ...
