Description

Technical Field

[0001] This utility model relates to the technical field of wet dust removal devices, and more specifically, to a compact and efficient pulse wet dust removal device. Background Technology

[0002] Wet scrubbers are high-efficiency dust removal devices that utilize the principle of liquid-gas contact. Through mechanisms such as spraying systems or water film formation, dust particles collide, adsorb, and agglomerate with liquid droplets, ultimately achieving gas-solid separation. During operation, the purified gas often carries tiny liquid droplets. Therefore, a wire mesh demister is typically installed at the exhaust end of the scrubber. This device, composed of multiple layers of specially woven wire mesh, effectively intercepts and removes residual mist from the gas, ensuring the cleanliness of the discharged gas.

[0003] However, certain technical limitations still exist in actual operation: when dealing with high-concentration dust, if the dust load inside the wet scrubber exceeds the design range (especially easily adherent dust such as quicklime), conventional spraying or washing systems often fail to achieve thorough cleaning. This unremoved dust moves with the airflow to the outlet section and is intercepted and filtered by the wire mesh demister. While this mechanism effectively prevents dust leakage, the continuous accumulation of dust causes the demister to gradually clog, increasing system resistance and significantly reducing overall dust removal efficiency, creating a vicious cycle. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a compact and efficient pulse wet dust removal device to solve the problem that when some wet dust collectors are equipped with wire mesh demisters in the prior art, high dust loads can easily cause the demisters to become clogged, which can intercept dust but will increase resistance and reduce dust removal efficiency.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a compact and efficient pulse-type wet dust collector, comprising...

[0006] A base plate, on the top of which an outer shell and a cover box are fixedly installed in sequence. A wire mesh demister body is fixedly sleeved on the inner wall of the top of the outer shell, and multiple spray systems are arranged below the wire mesh demister body. A fan is fixedly installed on the top of the inner cavity of the cover box. A connecting pipe is fixedly sleeved on the middle of the side of the cover box. The top end of the connecting pipe is fixedly sleeved with the top of the outer shell. An air outlet pipe is fixedly sleeved on the side end of the fan.

[0007] A fixing plate is fixedly installed on the outer surface of the top of the housing. An air bag body is installed on the lower surface of the fixing plate. Multiple electromagnetic pulse valves are sleeved on the top of the air bag body, and each of the multiple electromagnetic pulse valves is sleeved with a blow pipe.

[0008] The bottom of the outer shell is equipped with a sludge removal mechanism.

[0009] The dredging mechanism includes a partition plate and a motor. The outer surface of the partition plate is fixedly sleeved with the inner wall of the bottom of the outer casing. Two vertically arranged bevel gears are provided on the lower surface of the middle part of the partition plate, and the two bevel gears mesh with each other. The lower surface of the motor is fixedly installed with the upper surface of the bottom of the outer casing. The output end of the motor is fixedly sleeved with the middle part of one bevel gear, and an auger is fixedly sleeved with the end of the other bevel gear. A transmission pipe is sleeved on the outside of the auger. A scraper is fixedly sleeved with the output end of the motor, and the lower surface of the scraper is movably installed with the upper surface of the partition plate.

[0010] The outer surface of the transmission pipe is fixedly installed on the lower surface of the partition plate, the partition plate is opened at the feed inlet of the transmission pipe, and a feed pipe is fixedly sleeved at the end of the transmission pipe away from the motor.

[0011] An air inlet pipe is fixedly sleeved on the side wall of the bottom of the outer shell. An exhaust pipe is provided on the side of the air inlet pipe. A connecting plate and a U-shaped block are fixedly installed on the outer surfaces of the ends of the air inlet pipe and the exhaust pipe that are close to each other, respectively. A limit rod is fixedly installed in the middle of the connecting plate on the side close to the exhaust pipe. Two U-shaped buckles are slidably installed on the inner surface of the connecting plate. The two U-shaped buckles are symmetrically arranged, and the inner surface of the middle part is slidably sleeved with the outer surface of the limit rod. A spring is fixedly connected to the side of the two U-shaped buckles that are close to each other.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In the above scheme, by setting up structures such as the air tank body and the blower pipe, during the actual dust removal process, the dust-laden gas is discharged into the interior of the casing through the air inlet pipe, and at the same time, the fan and the spray system on the top of the casing are activated. During this process, the dust in the dust-laden gas is purified by the spray system. Then, when it passes through the wire mesh demister body, the wire mesh demister body removes the mist contained in the gas. Finally, the clean gas is drawn into the hood through the connecting pipe, and then discharged through the outlet pipe under the action of the fan. In addition, facing the wire mesh demister... The problem of dust removal efficiency being affected by dust accumulation at the bottom of the main body can be addressed by periodically controlling the air tank body and electromagnetic pulse valve. Compressed air inside the air tank body is then sprayed at high speed through a blowpipe onto the top of the wire mesh demister body, causing the dust accumulation at the bottom of the wire mesh demister body to be blown downwards and cleaned. This allows the pulse dust removal main equipment, consisting of the air tank body, blowpipe, and other structures, to be assembled at the top of the wet dust removal device. The pulse dust removal main equipment can then be used to periodically clean the dust accumulation in the wire mesh demister body, ensuring the working effect of the wet dust removal device.

[0014] In the above scheme, by setting up a sludge removal mechanism, the cleaned dust and mist will collect on the top of the partition plate at the bottom of the outer shell during the dust removal process. The motor can be started, and the bevel gear sleeved at the output end of the motor will rotate while driving another meshing bevel gear to rotate. The scraper and auger connected to the ends of the two bevel gears will move against the upper surface of the partition plate and rotate the inner wall of the transmission pipe, respectively. Thus, the scraper will scrape the accumulated sludge on the top of the partition plate to the corresponding opening of the transmission pipe. The rotating transmission pipe will transport the dust and mist together to the lower feed pipe. Thus, the above structure facilitates the cleaning of the accumulated sludge formed by dust and mist at the bottom of the outer shell inside the device, improving the practicality of the device.

A fan 5 is fixedly installed on the top of the inner cavity of the cover box 4. A connecting pipe 6 is fixedly sleeved on the middle of the side of the cover box 4. The top end of the connecting pipe 6 is fixedly sleeved with the top of the outer shell 2. An air outlet pipe 7 is fixedly sleeved on the side end of the fan 5.

[0025] A fixing plate 8 is fixedly installed on the outer surface of the top of the outer shell 2. An air bag body 9 is installed on the lower surface of the fixing plate 8. Multiple electromagnetic pulse valves 10 are sleeved on the top of the air bag body 9. Each of the multiple electromagnetic pulse valves 10 is sleeved with a blow pipe 11 on its side.

[0026] The bottom of the outer shell 2 is equipped with a dredging mechanism 12.

[0027] The dredging mechanism 12 includes a partition plate 120 and a motor 121. The outer surface of the partition plate 120 is fixedly sleeved with the inner wall of the bottom of the outer casing 2. Two vertically arranged bevel gears 122 are provided on the lower surface of the middle part of the partition plate 120. The two bevel gears 122 mesh with each other. The lower surface of the motor 121 is fixedly installed with the upper surface of the bottom of the outer casing 2. The output end of the motor 121 is fixedly sleeved with the middle part of one bevel gear 122, and the end of the other bevel gear 122 is fixedly sleeved with an auger 124. A transmission pipe 125 is sleeved on the outside of the auger 124. A scraper 123 is fixedly sleeved with the output end of the motor 121. The lower surface of the scraper 123 is movably installed with the upper surface of the partition plate 120.

[0028] The outer surface of the transmission pipe 125 is fixedly installed on the lower surface of the partition plate 120. The partition plate 120 is made open at the feed port position of the transmission pipe 125. The end of the transmission pipe 125 away from the motor 121 is fixedly sleeved with the feed pipe 126.

[0029] The bottom side wall of the outer casing 2 is fixedly fitted with an air inlet pipe 13, and an exhaust pipe 14 is provided on the side of the air inlet pipe 13. A connecting plate 16 and a U-shaped block 15 are respectively fixedly installed on the outer surfaces of the ends of the air inlet pipe 13 and the exhaust pipe 14 that are close to each other. A limit rod 19 is fixedly installed in the middle of the connecting plate 16 on the side close to the exhaust pipe 14.

When installing the intake pipe 13 at the bottom of the outer casing 2, the two U-shaped buckles 17 that are slidably installed inside the connecting plate 16 on the surface of the intake pipe 13 can be moved together towards each other. Then, the U-shaped block 15 installed on the surface of the exhaust pipe 14 is aligned with the connecting plate 16, and the two U-shaped buckles 17 are released. Under the elastic reset action of the spring 18, the two U-shaped buckles 17 will move away from each other along the surface of the connecting plate 16 and the limiting rod 19, and the aligned U-shaped block 15 will be snapped into the side of the connecting plate 16, realizing the pre-splitting treatment between the intake pipe 13 and the exhaust pipe 14, which facilitates the convenience and accuracy of fixing the two with bolts later.

[0030] The working process of this utility model is as follows:

[0031] In the actual dust removal process, the dust-laden gas is discharged into the interior of the outer casing 2 through the inlet pipe 13, and the fan 5 and the spray system on the top of the outer casing 2 are started at the same time. During this process, the dust in the dust-laden gas will be purified by the spray system. Then, when passing through the wire mesh demister body 3, the wire mesh demister body 3 removes the mist contained in the gas. Finally, the clean gas is drawn into the hood 4 through the connecting pipe 6, and then discharged through the outlet pipe 7 under the action of the fan 5. In addition, in view of the problem that the dust removal efficiency of the wire mesh demister body 3 is affected by the dust accumulation at the bottom, the air tank body 9 and the electromagnetic pulse valve 10 can be controlled periodically to spray the compressed air inside the air tank body 9 at high speed through the flowing spray pipe 11 onto the top of the wire mesh demister body 3, so that the dust accumulation at the bottom of the wire mesh demister body 3 is blown downward and cleaned.

[0032] During the dust removal process, the cleaned dust and mist will collect on the top of the partition plate 120 at the bottom of the outer casing 2. The motor 121 can be started. The bevel gear 122 connected to the output end of the motor 121 will rotate, which will drive the other bevel gear 122 to rotate. The scraper 123 and the auger 124 connected to the ends of the two bevel gears 122 will move against the upper surface of the partition plate 120 and rotate the inner wall of the transmission pipe 125, respectively. Thus, the scraper 123 scrapes the accumulated sediment on the top of the partition plate 120 to the corresponding opening of the transmission pipe 125. The rotating transmission pipe 125 will transport the dust and mist together to the feed pipe 126.
