Description

Technical Field

[0001] This utility model relates to the field of electrostatic precipitator technology, and in particular to an electrostatic precipitator with a filter-type porous anode plate. Background Technology

[0002] Currently, the anode plate is the core component of electrostatic precipitators, mainly used for dust collection and gas purification.

[0003] In the prior art, the use of porous anode plates can improve the flow state of flue gas in the electric field and make the dust-laden gas enter each anode tube more evenly. However, dust can be adsorbed onto the inner wall of the holes in the porous anode plate, causing blockage and reducing dust removal efficiency. For example, in the published document CN207478807U, the dust collected on the surface of the electrode plate is cleaned by rapping through the synergistic effect of the first through hole on the anode plate, the dust attachment mesh, the flow-blocking dust collection plate, and the porous dust collection plate. However, the rapping method cannot handle the dust adsorbed on the holes of the anode plate and the dust blocking the holes.

[0004] Therefore, the applicant hereby submits this application. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing an electrostatic precipitator with a filter-type porous anode plate, which cleans the dust inside the holes by simultaneously ejecting dust from the holes with a top block and blowing air.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: An electrostatic precipitator with a filter-type porous anode plate includes an electrostatic precipitator and an anode plate. The anode plate is installed inside the electrostatic precipitator. A plate is provided on one side of the anode plate. The anode plate is provided with a plurality of holes. A top block adapted to each of the holes is provided on the plate.

[0007] In the above scheme, preferably, the plate and the top block are made of insulating material.

[0008] In the above scheme, preferably, the plate has an inner cavity, the inner cavity is provided with a main pipe, one end of the main pipe is connected to a blower, the blower is located outside the electrostatic precipitator, and the other end of the main pipe is connected to a secondary pipe that communicates with each of the top blocks.

[0009] In the above scheme, preferably, the main pipe and each of the secondary pipes are made of insulating material.

[0010] In the above scheme, preferably, a cylinder is provided outside the electrostatic precipitator, the cylinder includes a piston rod, the piston rod passes through the side wall of the electrostatic precipitator, and its front end is connected and fixed to one side of the plate.

[0011] In the above scheme, preferably, the cylinder is a guide cylinder. In the above scheme, preferably, a support block is provided on the outer wall of the electrostatic precipitator, and the cylinder is located on the support block.

[0012] In the above scheme, preferably, the number of top blocks provided on the plate is the same as the number of holes provided on the anode plate, and each top block on the plate corresponds to each hole on the anode plate.

[0013] The beneficial effects of this utility model are: the guide cylinder drives the plate to push the top block on the plate to push out the dust accumulated in the hole of the anode plate. At the same time as pushing out, the dust left in the hole after pushing out is cleaned by blowing air. This can thoroughly clean the dust in the hole, avoid the accumulation of dust and blockage of the porous structure, ensure the capture efficiency of the electric field for dust, and improve the dust collection efficiency of the anode plate.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: See Figures 1-4 An electrostatic precipitator with a filter-type porous anode plate includes an electrostatic precipitator 1 and an anode plate 2. The anode plate 2 is installed inside the electrostatic precipitator 1 for dust collection and gas purification. To improve the high efficiency of filtration and dust collection of the anode plate 2, several holes 4 are provided on the anode plate 2. However, the presence of multiple holes 4 on the anode plate 2 can lead to dust adsorption on the hole walls, causing blockage inside the holes 4.

[0019] To handle the dust accumulated in the holes 4 of the anode plate 2, a plate 3 is provided on one side of the anode plate 2. Several top blocks 5 are provided on the plate 3. The size of the top blocks 5 is adapted to the size of the holes 4, so as to push out the dust accumulated in the holes 4. The number of top blocks 5 provided on the plate 3 is the same as the number of holes 4 provided on the anode plate 2. Each top block 5 on the plate 3 corresponds to each hole 4 on the anode plate 2.

[0020] Specifically, a cylinder 10 is installed on the outside of the electrostatic precipitator 1. The cylinder 10 includes a piston rod 11, which passes through the side wall of the electrostatic precipitator 1. The front end of the piston rod 11 is fixed to one side of the plate 3. When it is necessary to clean the dust in the hole 4 on the anode plate 2, the cylinder 10 operates to drive the plate 3 to move closer to the anode plate 2. The dust in the hole 4 of the anode plate 2 is pushed out by the provided top block 5. Since the anode plate 2 is charged in the electrostatic precipitator 1, the plate 3 is made of insulating material to prevent it from affecting the electric field of the anode plate 2 when in contact with it. The main purpose of using insulating material on the plate 3 in contact with the anode plate 2 is to prevent current leakage and ensure potential isolation, so as to avoid accidental connection between components with different potentials.

[0021] In this embodiment, cylinder 10 is a guide cylinder. The guide cylinder restricts the rotation of piston rod 11 through a built-in guide device to ensure the accuracy of the motion trajectory, avoid positioning deviation caused by vibration or off-center load, and improve the stability and durability of equipment operation.

[0022] Furthermore, since some dust remains on the wall of the anode plate 2 after the top block 5 ejects the dust from the hole 4, an inner cavity 6 is provided on the plate 3 to clean the dust. A main pipe 7 is installed on the inner cavity 6. One end of the main pipe 7 is connected to a blower 8, which is located outside the electrostatic precipitator 1. The other end of the main pipe 7 is connected to several auxiliary pipes 9, the number of which is the same as the number of top blocks 5. Each auxiliary pipe 9 is connected to each top block 5. When the blower 8 is working, each auxiliary pipe 9 blows out the dust remaining on the inner wall of the anode plate 2 through the gas flowing through the main pipe. The blowing operation is similar to the action of the top block 5 on the anode plate 2. The dust ejection process within the holes 4 is carried out simultaneously. The dust ejected from the holes 4 of the anode plate 2 by the top block 5 passes through the secondary pipe 9 set on each top block 5, which blows out the dust remaining on the hole wall of the anode plate 2. Thoroughly cleaning the dust inside the holes 4 can prevent the accumulation of dust from clogging the porous structure of the holes 4, ensuring the efficiency of the electric field in capturing dust and reducing the problem of reduced dust collection capacity caused by the blockage of the holes 4. After the dust inside the holes 4 of the anode plate 2 is cleaned, the guide cylinder is reset, the blower 8 is turned off, and the anode plate 2 continues to collect dust. The main pipe 7 and the secondary pipe 9 are both made of insulating material. The main pipe 7 and the secondary pipe 9, like the plate 3, must contact the anode plate 2 and are made of insulating material.

[0023] A support block 12 is fixedly installed on the outside of the electrostatic precipitator 1, and the guide cylinder is located on the support block 12, which can improve the installation stability of the guide cylinder. In this embodiment, since the wall of the electrostatic precipitator 1 is affected by the corrosive environment such as smoke and high temperature for a long time, the contact part between the piston rod 11 of the guide cylinder and the wall is prone to oxidation, which leads to the failure of the sealing ring and the occurrence of air leakage. The staff needs to regularly check the guide cylinder and perform maintenance or replacement.

[0024] Working principle: Through the operation of the guide cylinder, the piston rod 11 drives the plate 3 to move closer to the anode plate 2. The top block 5 on the plate 3 pushes out the dust in the hole 4 on the anode plate 2. At the same time as the dust is pushed out, the blower 8 starts to work. Since the blower 8 is connected to the main pipe 7, the main pipe 7 is connected to multiple auxiliary pipes 9, and each auxiliary pipe 9 is connected to each top block 5, while the top block 5 pushes out the dust in the hole 4 of the anode plate 2, the auxiliary pipes 9 on the top block 5 blow out the dust left on the hole wall of the anode plate 2. This can thoroughly clean the dust in the hole 4 of the anode plate 2, ensure the capture efficiency of the electric field for dust, and improve the dust collection efficiency of the anode plate 2.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
