Description

Technical Field

[0001] The utility model relates to flue gas dust removal technical equipment in the technical field of environmental protection, in particular to a wet electrostatic dust removal device. Background Art

[0002] In the prior art, the main principle of wet electrostatic precipitator is to energize the electrode tube to form a corona in the precipitator tube, thereby absorbing dust particles in the flue gas and achieving a dust removal effect.

[0003] Its specific structural setting, for example: the technical solution of application publication number: CN 116251678 A discloses "a vertical wet electrostatic precipitator", and this technical solution realizes dust removal by setting a sieve tube and a cathode wire inside the sieve tube.

[0004] For another example, the technical solution with authorization announcement number: CN 103203284 B discloses a “wet electrostatic precipitator”, which also adopts the form of a dust hood, arranges an electrode tube inside the dust hood, and then energizes to form a corona inside the dust hood to achieve dust removal.

[0005] However, in the above technical solutions, although the electrostatic principle can be used to form a corona inside the dust removal pipe to absorb dust particles, when removing these particles, it is necessary to use a spray assembly arranged above to achieve it.

[0006] However, when these dust particles are removed by spraying, after power failure, these dust particles may still be adsorbed in the pipe body. Even if they are sprayed by the spray component, sometimes they may not be effectively sprayed off the inner wall of the pipe body, which will seriously affect the dust removal efficiency and quality.

[0007] Therefore, in order to solve the above problems, it is necessary to develop a wet electrostatic precipitator with a reasonable structure that can improve work efficiency and work quality. Utility Model Content

[0028] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. The embodiments are implemented based on the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0029] like Figure 1 As shown, a wet electrostatic dust removal device of this embodiment includes a vertical dust removal box 1, a drain pipe 2 is provided at the bottom of the vertical dust removal box 1, an air inlet pipe 3 is provided on one side of the lower end of the vertical dust removal box 1, and an air outlet pipe 4 is provided at the upper end of the vertical dust removal box 1; a mobile electrostatic dust removal assembly is also provided in the vertical dust removal box 1;

[0030] The mobile electrostatic dust removal assembly includes an outer frame 5, the size of which is adapted to the inner wall size of the vertical dust removal box 1. The outer frame 5 is correspondingly arranged in the vertical dust removal box 1, and a plurality of closely arranged dust removal cylinders 6 are correspondingly arranged inside the outer frame 5. The dust removal cylinders 6 are vertically arranged and open at the top and bottom. The gas entering from the lower air inlet pipe 3 passes through the dust removal cylinders 6 and then is discharged upward from the air outlet pipe 4.

[0031] Each dust removal cylinder 6 is provided with an electrode tube 7, and the corresponding electrode tube 7 is consistent with the axis of the corresponding dust removal cylinder 6. The electrode tubes 7 extend upward and converge, and then extend to the outside of the vertical dust removal box 1 and are correspondingly connected and installed on the power supply assembly 8. The vertical dust removal box 1 is grounded through a wire.

[0032] A spray pipe 9 is also provided above the mobile electrostatic dust removal assembly. A spray port 10 is provided on the spray pipe 9. The spray port 10 is downwardly directed toward the dust removal cylinder 6 below. A spray mechanism 11 connected to the spray pipe 9 is correspondingly provided on the outside of the vertical dust removal cylinder 6.

[0033] A support frame 12 is also provided above the dust removal cylinder 6 , and the upper end of the electrode tube 7 is correspondingly fixed on the support frame 12 , so that the electrode tube 7 is drooped and fixed in the dust removal cylinder 6 .

[0034] The electrode tube 7 is also provided with a transverse portion 13 with uniform upper and lower intervals.

[0035] A vertical groove 14 is also provided on the side wall of the vertical dust removal box 1; and a vertical rack 15 is provided on the outer wall of the outer frame 5, and the vertical rack 15 extends from the position of the vertical groove 14 accordingly, and the dimensions of the vertical rack 15 and the vertical groove 14 are set accordingly, so that the vertical rack 15 has space to move up and down in the vertical groove 14;

[0036] A driving mechanism 16 is also provided on the outside of the vertical dust removal box 1, and a driving gear 17 is installed on the driving mechanism 16. The driving gear 17 is meshed with the vertical rack 15 on the outer frame 5. Through the cooperation of the driving gear 17 and the vertical rack 15, the inner outer frame 5 and the dust removal cylinder 6 inside the outer frame 5 can move up and down.

[0037] like Figure 3 As shown, the outer frame 5 and the vertical dust removal box 1 are both configured as circular structures, while the internal dust removal cylinder 6 is configured as a hexagonal cylinder structure; there are three vertical racks 15 on the outside of the outer frame 5.

[0038] like Figure 2 As shown, the outer frame 5 and the vertical dust removal box 1 are both arranged as a cubic structure, the internal dust removal cylinder 6 is arranged as a square structure, and there are four vertical racks 15 outside the outer frame 5.

[0039] A sealing gasket is also provided between the outer frame 5 and the vertical dust removal box 1 .

[0040] The specific working process of this device is as follows: after the electrode tube in the dust removal tube of this device is powered by an external power supply component, a corona will be generated inside the dust removal tube. Then, the tiny particles in the flue gas will be charged under the action of the corona, and the tiny particles will be adsorbed on the inner wall of the dust removal tube, thereby removing these tiny particles.

[0041] When there are many tiny particles gathered on the inner wall of the dust removal tube, the spray pipe on the top can be opened, and the water sprayed from the spray pipe will enter the dust removal tube to clean the tiny particles on the inner wall of the tube.

[0042] At the same time, in order to increase the cleaning efficiency and cleaning quality, a vertical rack is arranged on the outer wall of the outer frame in the present device, and the box body of the vertical dust removal box is provided with a vertical groove corresponding to the position of the vertical rack. The vertical rack extends from the position of the vertical groove, and a driving mechanism and a driving wheel are also arranged on the outside, and the driving wheel is meshed and installed with the vertical rack.

[0043] After this arrangement, when cleaning is carried out, the vertical rack can be driven up and down by the external driving wheel, and the internal outer frame and the dust removal cylinder inside the outer frame can be driven up and down at the same time. After the dust removal cylinder moves up and down, the dust particles accumulated on the inner wall will be easier to clean, and because the internal electrode tube is coaxially arranged and does not contact the inner wall of the dust removal cylinder, it will not affect the installation of the internal electrode tube.

[0044] In addition, the dust removal cylinder on the inside is an integrated structure, which can be raised and lowered simultaneously with the outer frame, and the lifting height and the reciprocating frequency of the lifting can be set accordingly to increase the spray cleaning effect of the spray mechanism. The overall structural design is very ingenious and reasonable.

[0045] The specific design of the dust collector in this device can be set to a square structure or a circular structure. On the one hand, it can ensure that the smoke passes through all the dust collectors from the bottom to the top. On the other hand, the overall structure is easier to place in a vertical dust collector box and can move up and down more smoothly in the vertical dust collector box.

[0046] At the same time, the device also needs to maintain the sealing performance of the vertical dust removal box when it moves up and down, to ensure that the smoke and cleaning water will not leak from the position of the vertical groove, so a sealing gasket can be set between the vertical dust removal box and the dust removal cylinder.

[0047] After the dust removal barrel moves up and down for cleaning, it needs to return to its original position before dust removal can be carried out again. The overall structural setting is relatively reasonable and ingenious; and the water sprayed from the upper sprinkler pipe is drained from the drain pipe directly below, which will not hinder the air intake of the intake pipe.

[0048] The above-mentioned specific implementation mode is only a preferred embodiment of the present invention and is not intended to limit the implementation of the present invention and the scope of the claims. All equivalent changes and modifications made according to the content of the patent protection scope of the present invention should be included in the scope of the patent application of the present invention.
