Abstract

The present invention relates to the technical field of electrostatic separation equipment, and specifically to a spray-washing wet electrostatic precipitator, which includes a shell, an adsorption mechanism, a spray mechanism and a collection mechanism; the shell has a plurality of closely packed rows and columns of adsorption chambers, two of the four side walls of the adsorption chamber are swingable anode plates, and a cathode rod is inserted in the adsorption chamber. The present invention arranges an air pump to allow air to intermittently enter the shell from the air inlet at a high frequency, so that the air pressure in the adsorption chamber increases and decreases reciprocally, and uses the Bernoulli principle to cause the anode plate to cyclically fluctuate, thereby causing the electric field in the adsorption chamber to change reciprocally. After the air leaves the preset height of the anode plate, the air pressure at the preset height position decreases, and the anode plate at this position is close to the cathode rod, and the electric field strength in the adsorption chamber increases.

Description

Technical Field

[0001] The invention relates to the technical field of electrostatic separation equipment, and in particular to a spray-washing wet electrostatic precipitator. Background Art

[0002] Wet electrostatic precipitator (WESP) is a new type of dust removal equipment used to treat dust and fine particles. With its efficient dust removal performance, wide range of applications and stable and durable characteristics, wet electrostatic precipitator plays an important role in advanced environmental protection industry and is widely used in many industrial fields, such as electricity, steel, cement, petrochemical, wood processing and papermaking, medicine, food, printing and dyeing and textile, etc.

[0003] The working principle of the wet electrostatic precipitator mainly relies on the combined effect of the electrostatic field and the water spray system. Inside the precipitator, a strong electric field is generated between the discharge electrode and the collecting electrode through a high-voltage DC power supply. When the dust-containing flue gas enters the electric field, the dust particles are charged under the action of the electric field force, move toward the collecting electrode, and are finally captured. At the same time, the water spray system sprays water mist to the discharge electrode and the corona area. The water mist is charged and further atomized under the action of the electric field, thereby enhancing the dust capture effect. The captured dust is washed into the ash hopper and discharged with water. However, in the dust removal process of the existing dust collector, water stains are easily formed on the dust collecting plate. After the dust contacts with the water stains, it cannot be smoothly separated from the dust collecting plate. For this reason, the Chinese patent document with the publication number CN218459796U discloses a wet electrostatic precipitator, which removes the water stains on the dust collecting plate by a scraper. However, in combination with the above patents and the prior art, the wet electrostatic precipitator has the problems of low dust removal efficiency and poor dust removal effect in the dust removal process.

In addition, when air passes through the adsorption chamber, the anode plate and the outer plate can move relative to each other and collide, thereby cleaning the dust particles on the surface of the anode plate and the baffle, and avoiding the problem of water stains on the surface of the anode plate, which causes dust particles to adhere to the water stains and cannot be separated from the anode plate, thereby extending the service life.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0039] like Figures 1 to 13 As shown, a spray-washing wet electrostatic precipitator provided in an embodiment of the present invention includes a shell 100, an adsorption mechanism, a spray mechanism and a collection mechanism.

[0040] The shell 100 is an internal hollow structure, in which a mounting frame 110 is fixedly connected in the middle; an exhaust port 102 is provided on the upper side of the shell 100, and an air inlet 101 is provided on the lower side wall of the shell 100, and an air pump is connected to the air inlet 101, which allows air to intermittently enter the shell 100 at a high frequency; a high-voltage power supply is installed in the shell 100; a supporting leg 107 is connected to the lower part of the shell 100; an inspection platform 104 is arranged outside the shell 100; an inspection staircase 105 is also fixedly installed outside the shell 100, and the upper end of the inspection staircase 105 leads to the inspection platform 104. The inspection staircase 105 is provided with a protective net 106.

[0041] The adsorption mechanism is installed on the mounting frame 110, and includes a plurality of adsorption units closely arranged along the first direction. The adsorption unit includes two partitions 200, a plurality of anode plates 210 and a plurality of cathode rods 212; the two partitions 200 are arranged at intervals along the first direction, the partitions 200 are arranged vertically and extend along the second direction, the second direction and the first direction are both horizontal and perpendicular to each other, wherein the first direction is the front-to-back direction, and the second direction is the left-to-right direction; the upper and lower ends of the partitions 200 are fixedly connected to the mounting frame 110;

[0042] Support frames 220 are arranged on both upper and lower sides of the mounting frame 110, and the two support frames 220 are connected by a cathode connecting line 221. A plurality of cathode rods 212 are arranged at intervals along the second direction, and thorns are arranged on the surface of the cathode rods 212. The upper and lower ends of the cathode rods 212 are respectively fixedly connected to the two support frames 220; a plurality of anode plates 210 are arranged at intervals along the second direction, and the two ends of the anode plates 210 in the first direction are respectively abutted against the two partitions 200, and at least one anode plate 210 is respectively arranged on both sides of the cathode rods 212 in the second direction, wherein two anode plates 210 are arranged between two adjacent cathode rods 212, and the two anode plates 210 on both sides of the two partitions 200 and the cathode rods 212 are limited. An adsorption chamber 211 is defined, and a cathode rod 212 is located in the adsorption chamber 211; a distance between two anode plates 210 between two adjacent cathode rods 212 is smaller than a distance between two anode plates 210 constituting the adsorption chamber 211; a length of the anode plate 210 is greater than a vertical length of the partition 200, and the anode plate 210 is bent from top to bottom and arranged between the two partitions 200, and the upper end of the anode plate 210 is rotatably mounted on the mounting frame 110, and the axis of rotation extends along a first direction; the lower end of the anode plate 210 is movably mounted on the mounting frame 110 along a second direction; all anode plates 210 are connected to the positive pole of a high-voltage power supply; and all cathode rods 212 are connected to the negative pole of the high-voltage power supply.

[0043] The spray mechanism is installed in the housing 100 and is used to spray water mist evenly to the adsorption mechanism.

[0044] The collecting mechanism is installed in the housing 100 and is used to collect dirt dropped from the adsorption mechanism.

[0045] During use, the air pump and the high-voltage power supply are started, and the air pump allows the dusty air to intermittently enter the housing 100 from the air inlet 101 at a high frequency, and the length of the air introduced into the adsorption chamber 211 each time in the vertical direction is less than the vertical height of the partition 200. According to the Bernoulli principle, when the upper end of the single air introduction reaches the preset height, the air pressure at the preset height increases rapidly, and the air pushes the part of the anode plate 210 located at this height to both sides, so that the distance between the two anode plates 210 increases; after the lower end of the single air introduction leaves the preset height, the air pressure at the preset height decreases rapidly, and the part of the anode plate 210 located at this height moves toward the cathode rod 212, and the distance between the two anode plates 210 decreases.

[0046] Since the anode plate 210 is connected to the positive electrode of the high-voltage power supply, and the cathode rod 212 is connected to the negative electrode of the high-voltage power supply, an electric field is generated in the adsorption chamber 211 after the high-voltage power supply is started; after the air enters the shell 100, the air carries the dust and moves from bottom to top. The air enters the adsorption chamber 211 from the lower end, and the cathode rod 212 discharges and releases a large number of electrons. After the electrons collide with the dust particles, they adhere to the dust particles. Thereafter, the dust particles are negatively charged. The negatively charged dust particles move toward the anode plate 210 under the action of the electric field force. After the dust particles come into contact with the anode plate 210, they release the charge and are deposited on the surface of the anode plate 210, thereby separating the dust particles in the air from the air.

[0047] As air is continuously introduced, the thickness of the dust particles deposited on the anode plate 210 gradually increases, and the dust gradually forms an insulating layer on the anode plate 210, weakening the electric field strength between the anode plate 210 and the cathode rod 212, affecting the separation efficiency and effect of the dust particles and the air. At this time, the spray mechanism is started to spray water mist onto the adsorption mechanism; the water mist particles collide and agglomerate with the charged dust particles in the air and on the anode plate 210 under the action of the electric field force to form larger particles, which move downward under the action of gravity and fall from under the adsorption mechanism; the fallen dirt and escaping water vapor are collected by the collection mechanism, and the clean air is discharged from the shell 100 from the exhaust port 102.

[0048] The present invention arranges the air pump to allow air to intermittently enter the shell 100 from the air inlet 101 at a high frequency, so that the anode plate 210 fluctuates back and forth in a wave-like manner, and then the electric field in the adsorption chamber 211 changes back and forth. After the air leaves the anode plate 210 at a certain height, the distance between the anode plates 210 decreases, the distance between the anode plate 210 and the cathode rod 212 decreases, and the electric field strength in the adsorption chamber 211 increases. At this time, the charged dust particles in the adsorption chamber 211 are subjected to a greater electric field force, thereby increasing the adsorption capacity of the charged dust particles by the anode plate 210, improving the dust removal efficiency, and optimizing the dust removal effect.

[0049] In a further embodiment, Fig. 9 , Fig.10 As shown, a plurality of baffles 213 are connected to one side of the anode plate 210 facing the adsorption chamber 211 , and the plurality of baffles 213 are arranged at intervals up and down.

[0050] After the high-voltage power supply is started, an electric field is generated in the adsorption chamber 211; after the air enters the shell 100, the air carries the dust and moves from bottom to top. After the dust particles enter the electric field, they are negatively charged and move toward the anode plate 210 under the action of the electric field force, and are deposited on the surface of the anode plate 210. As the air is continuously intermittently passed from bottom to top, the anode plate 210 fluctuates, and the dust particles deposited on the anode plate 210 move upward, and the dust accumulates on the lower surface of the baffle 213. Under the premise of adsorbing the same amount of dust, the thickness of the dust layer deposited on the anode plate 210 is reduced, thereby slowing down the speed at which the electric field strength decreases, and more dust can be adsorbed, further enhancing the dust removal effect and improving the dust removal efficiency.

[0051] In a further embodiment, Figure 3 , Figure 5 As shown, the spray mechanism includes an upper sprayer 300, a lower sprayer 310, a water pump and a water tank. The upper sprayer 300 is located above the adsorption mechanism, and the lower sprayer 310 is located below the adsorption mechanism. The upper sprayer 300 and the lower sprayer 310 are fixedly connected with a spray head on one side facing the adsorption mechanism. The upper sprayer 300 and the lower sprayer 310 are connected to the water tank through a pipe, and a water pump is connected to the pipe.

[0052] The collecting mechanism includes an upper collecting chamber 400, a lower collecting chamber 410 and a drain pipe. The upper collecting chamber 400 is located above the adsorption mechanism, and is used to collect water vapor overflowing from the top of the adsorption mechanism. The lower collecting chamber 410 is located below the adsorption mechanism, and is used to collect dirt dropped from the adsorption mechanism. The lower collecting chamber 410 is connected to the drain pipe. A drain port 103 is opened on the shell 100, and the drain pipe is connected to the drain port 103.

[0053] When spraying is required, the water pump is started, and the water pump pumps the liquid in the water tank into the upper sprayer 300 and the lower sprayer 310. The upper sprayer 300 sprays water mist from top to bottom, and the lower sprayer 310 sprays water mist from bottom to top, so that the spraying is more uniform, and the dust particles can collide and condense with the water mist more fully, further optimizing the dust removal effect. After the dust particles collide and condense with the water mist, they fall into the lower collection chamber 410 under the action of gravity and are discharged from the housing 100 through the sewage pipe. Part of the water vapor escapes from the top of the adsorption mechanism and is collected by the upper collection chamber 400.

[0054] In a further embodiment, the spraying intensity of the lower sprayer 310 is greater than the spraying intensity of the upper sprayer 300 .

[0055] like Figure 7 , Fig. 9 , Fig.10 As shown, an outer plate 214 is provided on the side of each anode plate 210 away from the adsorption chamber 211, and the upper and lower ends of the outer plate 214 are respectively connected to the mounting frame 110; the upper and lower ends of the anode plate 210 are fixedly connected to a blocking plate, and the other end of the blocking plate is fixedly connected to the outer plate 214, and the blocking plate is used to block the gap between the outer plate 214 and the anode plate 210; the baffle 213 is fixedly connected to the outer plate 214, and a through hole is opened at a corresponding position on the anode plate 210, and the baffle 213 passes through the through hole and points to the adsorption chamber 211. Attachment chamber 211; one end of the baffle 213 facing the adsorption chamber 211 is fixedly connected to the limiting plate 215; the lower surface of the baffle 213 away from the outer plate 214 is provided with a receiving groove 216; the lower surface of the baffle 213 is provided with a locking spring 217, the locking spring 217 extends along the second direction, and is in a V-shape with the opening upward, and can be deformed, and the end of the locking spring 217 away from the outer plate 214 is fixedly connected to the baffle 213; the locking spring 217 can be received in the receiving groove 216 when deformed.

[0056] In the initial state, the locking spring 217 protrudes out of the receiving groove 216. After the high-voltage power supply is started, an electric field is generated in the adsorption chamber 211; the air pump allows air to intermittently enter the shell 100 at a high frequency, and the anode plate 210 fluctuates back and forth in a wave-like manner. When the part of the anode plate 210 and the baffle 213 at the same height is close to the cathode rod 212, the cathode rod 212 abuts against the locking spring 217, and drives the outer plate 214 to synchronously approach the cathode rod 212; when the anode plate 210 is away from the cathode rod 212, the outer plate 214 remains stationary, and the anode plate 210 collides with the outer plate 214, thereby avoiding the problem of water stains on the surface of the anode plate 210, which causes dust particles to adhere to the water stains and cannot be separated from the anode plate 210.

[0057] As air continues to flow in from bottom to top, dust accumulates on the surface of the anode plate 210 and the lower surface of the baffle 213. In order to ensure the dust removal efficiency and effect, the spray mechanism is started to spray water mist onto the adsorption mechanism; under the action of wind, dust particles that have not come into contact with the water mist or dust that has come into contact with the water mist but is not sufficient to move downward under the action of gravity accumulate on the lower surface of the baffle 213, giving the locking spring 217 an upward force. When the dust and water vapor on the lower surface of the baffle 213 accumulate to a preset amount, the force applied to the locking spring 217 causes it to undergo elastic deformation and be stored in the accommodating groove 216. At this time, the baffle 213 can move freely in the through hole.

[0058] When the air leaves the height where the baffle 213 is located, the air pressure at this height decreases, the anode plate 210 approaches the cathode rod 212, while the outer plate 214 remains stationary, and the anode plate 210 moves away from the outer plate 214. The anode plate 210 pushes the dust particles accumulated on the upper surface of the baffle 213 and the lower surface of the locking spring 217 toward the cathode rod 212. Thereafter, in conjunction with the spraying effect, the dust particles move downward under the action of gravity and fall into the lower collecting chamber 410; the limit plate 215 prevents the baffle 213 from slipping out of the through hole; when the air introduced reaches this height next time, the air pressure at this height increases, the anode plate 210 moves away from the cathode rod 212, and returns to its initial state. At this time, the locking spring 217 is no longer affected by the force of the dust particles and automatically returns to its initial state.

[0059] In a further embodiment, Fig.10 As shown, the limiting plate 215 is V-shaped with its opening facing the anode plate 210 , and the middle portion of the limiting plate 215 is fixedly connected to one end of the baffle 213 facing the adsorption chamber 211 .

[0060] After the anode plate 210 moves a preset distance relative to the outer plate 214 toward the cathode rod 212 , the anode plate 210 contacts the limit plate 215 , and when the spray mechanism sprays water mist, the dust particles attached to the anode plate 210 can smoothly fall into the lower collection chamber 410 .

[0061] In a further embodiment, Figure 3 , Figure 5 As shown, a uniform distribution plate 150 is provided at the lower end of the adsorption mechanism, and the uniform distribution plate 150 is located above the air inlet 101 and below the lower sprayer 310. The uniform distribution plate 150 is used to guide the smoke to be evenly distributed on the lower surface of the adsorption mechanism, and to perform primary filtration on the air, and separate the large-diameter dust in the air from the air. In the subsequent spraying process, the large-diameter dust intercepted by the uniform distribution plate 150 collides and agglomerates with the dust falling from the adsorption mechanism, and falls to the lower collection chamber 410 under the action of gravity, and is discharged from the housing 100 from the sewage pipe.

[0062] In a further embodiment, Figure 6 , Fig.11As shown, the mounting frame 110 includes an upper supporting grid 120, a lower supporting grid 130 and a connecting frame 140; the upper supporting grid 120 and the lower supporting grid 130 are installed in the middle of the housing 100, and the lower supporting grid 130 is located at a preset distance below the upper supporting grid 120; the two are connected by the connecting frame 140, and the adsorption mechanism is installed in the mounting frame 110; the upper supporting grid 120 and the lower supporting grid 130 each include a plurality of first metal strips 121 and a plurality of second metal strips 122 arranged horizontally, the first metal strips 121 extend along the first direction and are arranged at equal intervals in the second direction; the second metal strips 122 extend along the second direction and are arranged at equal intervals in the first direction; The first metal strip 121 and the second metal strip 122 are closely interwoven to form a grid; the upper end of the anode plate 210 is rotatably installed between two adjacent second metal strips 122 of the upper support grid 120, and a slide groove 123 is provided on the second metal strip 122 of the lower support grid 130, and the slide groove 123 extends along the second direction, and the lower ends of the anode plate 210 and the outer plate 214 can be slidably installed in the slide groove 123; the gap between the upper ends and the gap between the lower ends of the two partitions 200 close to each other of the two adjacent adsorption units are blocked by the second metal strip 122; the gap between the upper ends and the gap between the lower ends of the two outer plates 214 between the two adjacent cathode rods 212 are blocked by the first metal strip 121.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
