Description

Technical Field

[0001] This invention relates to the field of waste gas treatment technology, specifically to a waste gas treatment device for industrial boilers. Background Technology

[0002] Industrial boilers generate exhaust gases containing various pollutants such as dust and sulfur dioxide during operation, which seriously pollute the atmospheric environment. If not treated thoroughly, they will still cause air pollution. Therefore, when industrial boilers are in operation, exhaust gas treatment equipment is needed to comprehensively treat the exhaust gas discharged from the boiler to ensure that the flue gas containing pollutants such as dust and sulfur dioxide generated by the combustion of industrial boilers is purified more completely and to prevent air pollution.

[0003] When exhaust gas treatment equipment purifies flue gas from industrial boilers, it is usually necessary to first filter and remove large particulate dust and suspended solids in the exhaust gas through a pretreatment tank, and then gradually introduce the gas into a desulfurization tank for secondary desulfurization treatment through a long conveying pipeline. However, in the existing technology, the pretreatment tank and the desulfurization tank are mostly independent and separate structures. Both are large in size and have a low degree of integration. The components are connected by long pipelines, which not only results in a large footprint and bulky structure of the overall equipment, but also increases the resistance along the pipeline and the risk of air leakage. This seriously affects the ease of installation and site utilization efficiency of the equipment, and also increases the difficulty and cost of subsequent operation and maintenance.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention utilizes a method where waste gas from an industrial boiler is discharged at high speed through a tangential inlet into a dust collection tank, creating a strong rotating airflow. Dust particles are thrown against the tank wall by centrifugal force and slide down to the bottom dust collection box for collection. The purified gas is then discharged upwards through a central circular pipe, achieving gas-solid separation. The gas then enters the dust collection box through a fan and connecting pipe, where it is blown towards a baffle. Remaining dust particles in the gas are blocked by the baffle and slide down to the second dust collection box, achieving gas-solid separation again. The purified gas then enters the desulfurization tower through a connecting pipe from the dispersion head for desulfurization treatment. Due to the combination of cyclone and baffle dust collection, a smaller dust collection tank and dust collection box can remove dust particles from the gas, greatly reducing the overall footprint of the equipment and the distance of pipeline connections. This also reduces pipeline resistance and the risk of air leakage, improving the ease of installation and site utilization efficiency. However, it also increases the difficulty and cost of subsequent operation and maintenance.

[0016] The gas is dispersed into the absorbent liquid inside the desulfurization tower through the dispersing head via the connecting pipe. The absorbent liquid desulfurizes the dispersed gas, making the desulfurization more thorough. The gas is then conveyed upwards, and the pump body draws the absorbent liquid from the connecting box and the inside of the desulfurization tower. The liquid is then sprayed out from the nozzle through the conveying pipe, fixed pipe, ring pipe, and hose. The sprayed absorbent liquid absorbs sulfur dioxide in the gas again, making the sulfur dioxide absorption and removal in the gas more thorough, ensuring the quality of waste gas treatment, and preventing air pollution. By turning on the motor, the circular plate and cylinder rotate. The cylinder drives the moving frame and moving column to move back and forth. The moving column drives the adjusting frame to move back and forth. The adjusting frame drives the control column and the circular frame to rotate back and forth at a certain angle. The two sets of adjusting grooves on the circular frame drive several adjusting rods and concave frames to move back and forth alternately. The strip grooves on the concave frame drive the adjusting column and connecting strip to swing back and forth in an arc, driving the rotating shaft and nozzles to swing. The two sets of nozzles swing in an arc alternately. The absorbent liquid sprayed from the nozzles is evenly and comprehensively sprayed into the gas, which fully absorbs the sulfur dioxide in the gas, further ensuring the quality of waste gas treatment and protecting the atmospheric environment.

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0021] like Figures 1-11 As shown, this application provides an industrial boiler exhaust gas treatment device, including: a base 1, a desulfurization tower 101 installed on the top surface of the base 1, an exhaust pipe 102 installed at the upper end of the desulfurization tower 101, and an observation window 103 installed on the outer wall of the desulfurization tower 101.

[0022] The dust removal mechanism 2 is located above the base 1. The dust removal mechanism 2 includes a support frame 201 fixedly installed on the top surface of the base 1, a dust removal tank 202 fixedly installed on the inner wall of the support frame 201, and a dust removal box 208 fixedly installed on the top surface of the support frame 201. Specifically, such as Figures 1-3 As shown, a dust collection box 203 is installed at the lower end of the dust collection tank 202, a circular pipe 205 is fixedly installed through the upper end of the dust collection tank 202, an air inlet 204 is provided on the outer wall of the dust collection tank 202, a fan 206 is fixedly installed on the top surface of the dust collection tank 202, one end of the fan 206 is connected to the dust collection box 208 through a connecting pipe 207, and the fan 206 is connected to the circular pipe 205.

[0023] In this embodiment: the dust collection tank 202 is designed with a downward-facing cone shape at the lower end, and the air inlet 204 is designed as a tangential air inlet 204. When the gas enters the dust collection tank 202 from the air inlet 204, it forms a strong rotating airflow. The dust particles are thrown against the wall of the dust collection tank 202 under the action of centrifugal force and slide down the wall to the bottom dust collection box 203 for collection. The purified gas is discharged upward through the central circular pipe 205, thus realizing gas-solid separation.

[0024] Specifically, such as Figures 1-3 As shown, multiple baffles 210 are fixedly installed on the inner wall of the dust collector 208. The baffles 210 are inclined. The lower end of the dust collector 208 is connected to the dust collection box 209. A connecting pipe 211 is fixedly installed through the side of the dust collector 208. The other end of the connecting pipe 211 is fixedly connected through the desulfurization tower 101 and extends into the interior of the desulfurization tower 101. A dispersing head 212 is installed at one end of the connecting pipe 211.

[0025] In this embodiment: when gas enters the dust collector box 208, it is blocked by the baffle 210, which separates the dust particles into the dust collection box 209. The gas continues to be transported from one end of the dust collector box 208, thus achieving gas-solid separation.

[0026] The spraying mechanism 3 is located inside the desulfurization tower 101. The spraying mechanism 3 includes a fixed frame 304 fixedly installed on the inner wall of the desulfurization tower 101. Multiple nozzles 309 are provided below the fixed frame 304. A fixed pipe 305 is fixedly installed through the inner wall of the desulfurization tower 101. Specifically, such as Figures 2-4 As shown, a connecting box 301 is fixedly connected to the outer wall of the desulfurization tower 101, and a pump body 302 is fixedly installed on the top surface of the base 1. The connecting box 301 is connected to the pump body 302, and the pump body 302 is connected to the fixed pipe 305 through the conveying pipe 303. A filter plate 311 is fixedly installed on the inner wall of the desulfurization tower 101.

[0027] In this embodiment: through the connection box 301 and the pump body 302, the pump body 302 draws the absorbent liquid inside the connection box 301 and the desulfurization tower 101 and delivers it to the nozzle 309 for spraying. The absorbent liquid absorbs sulfur dioxide in the gas again, ensuring that the gas purification is more comprehensive and thorough.

[0028] Specifically, such as Figures 6-7 As shown, the other end of the fixed pipe 305 is connected to the annular pipe 306. The outer wall of the annular pipe 306 is fixedly connected to the top surface of the fixed frame 304 through the support column 307. The fixed frame 304 is provided with multiple through holes 310. The annular pipe 306 is connected to multiple nozzles 309 through multiple hoses 308.

[0029] In this embodiment: the absorbent enters the annular pipe 306 from the fixed pipe 305, and is then sprayed into the desulfurization tower 101 from multiple nozzles 309 through the hose 308 to fully absorb sulfur dioxide in the gas.

[0030] The swing mechanism 4 is located inside the desulfurization tower 101. The swing mechanism 4 includes multiple sets of connecting plates 401 fixedly installed on the bottom surface of the fixed frame 304. A rotating shaft 402 is fixedly installed on the outer wall of the nozzle 309. A connecting strip 403 is fixedly installed on the outer wall of the rotating shaft 402.

[0031] Specifically, such as Figure 10 As shown, one end of the rotating shaft 402 rotates through the connecting plate 401 via a bearing and extends to the other side of the connecting plate 401. One end of the connecting strip 403 is fixedly installed with an adjusting column 404. An arc groove 405 is provided on the side of the connecting plate 401. The outer wall of one end of the adjusting column 404 is slidably connected to the inner wall of the arc groove 405.

[0032] In this embodiment: the arc-shaped groove 405 limits the adjustment column 404. During the swinging process of the adjustment column 404 and the connecting bar 403, the adjustment column 404 and the connecting bar 403 swing more stably, and at the same time drive the rotating shaft 402 and the nozzle 309 to swing, increasing the area of ​​the nozzle 309 spraying the absorbent liquid, so that the nozzle 309 sprays the absorbent liquid more evenly.

[0033] Specifically, such as Figures 9-10 As shown, the bottom surface of the fixed frame 304 is provided with multiple T-shaped grooves 409, and T-shaped blocks 408 are slidably installed on the inner wall of the T-shaped grooves 409. A concave frame 406 is fixedly installed on the bottom surface of the T-shaped blocks 408. A strip groove 407 is provided through the side of the concave frame 406. The inner wall of the strip groove 407 is slidably connected to the outer wall of the adjusting column 404. An adjusting rod 423 is fixedly installed on the bottom surface of the concave frame 406.

[0034] In this embodiment: the T-shaped groove 409 is used to limit the T-shaped block 408, so that the T-shaped block 408 and the concave frame 406 move more stably. When the concave frame 406 moves, the strip groove 407 on the concave frame 406 drives the adjusting column 404 to swing.

[0035] Specifically, such as Figure 8 As shown, a circular sleeve 420 is fixedly installed on the bottom surface of the fixed frame 304. A circular frame 421 is rotatably installed on the outer wall of the circular sleeve 420 through a bearing. Two sets of adjustment grooves 422 are provided through the circular frame 421. Each set of adjustment grooves 422 has several grooves. The two sets of adjustment grooves 422 are arc-shaped with opposite arc angles. The two sets of adjustment grooves 422 are staggered. The inner wall of the adjustment groove 422 is slidably connected to the outer wall of the adjustment rod 423.

[0036] In this embodiment: two sets of adjustment grooves 422 are set in an arc shape with opposite arc angles and are staggered. When the circular frame 421 rotates a certain angle, it drives the two sets of adjustment grooves 422 to rotate a certain angle, which in turn drives the adjustment rod 423 and the concave frame 406 to move, further driving multiple nozzles 309 to swing back and forth in an alternating manner. The absorbent liquid sprayed by the nozzles 309 absorbs sulfur dioxide in the gas more thoroughly.

[0037] Specifically, such as Figures 5-7As shown, a fixed plate 410 is fixedly installed on the outer wall of the desulfurization tower 101. Two limiting shells 411 are fixedly installed on the side of the fixed plate 410. A movable frame 412 is slidably installed on the inner wall of the limiting shell 411. A fixed bracket 413 is fixedly installed on the side of the limiting shell 411. A motor 414 is fixedly installed on the side of the fixed bracket 413. The output rod of the motor 414 rotates through the fixed bracket 413 and is fixedly installed on a circular plate 415. A cylinder 416 is fixedly installed on the side of the circular plate 415. The outer wall of the cylinder 416 is slidably connected to the inner wall of the movable frame 412. A movable column 417 is fixedly installed on the side of the movable frame 412.

[0038] In this embodiment: the motor 414 drives the circular plate 415 and the cylinder 416 to rotate, the cylinder 416 drives the moving frame 412 to move back and forth, the moving frame 412 drives the moving column 417 to move back and forth, and the inner wall of the limiting shell 411 limits the moving frame 412, making the movement of the moving frame 412 more stable and improving the stability of the movement of the moving frame 412 and the moving column 417.

[0039] Specifically, such as Figure 7 As shown, one end of the movable column 417 slides through the outer wall of the desulfurization tower 101 and is fixedly installed with an adjusting frame 418. A control column 419 is fixedly installed on the bottom surface of the circular frame 421, and the outer wall of the control column 419 is slidably connected to the inner wall of the adjusting frame 418.

[0040] In this embodiment: when the movable column 417 moves back and forth, it drives the adjustment frame 418 to move back and forth, and the adjustment frame 418 drives the control column 419 and the circular frame 421 to rotate back and forth by a certain angle.

[0041] Specifically, the waste gas from the industrial boiler is discharged at high speed from the tangential inlet 204 into the dust collector 202, forming a strong rotating airflow. Dust particles are thrown against the wall of the dust collector 202 under centrifugal force, sliding down the wall and being collected in the bottom dust collection box 203. The purified gas is discharged upwards through the central circular pipe 205, achieving gas-solid separation. The gas then enters the dust collector box 208 through the fan 206 and connecting pipe 207. The gas is blown towards the baffle 210, where remaining dust particles are blocked and slide down into the second dust collection box 209, achieving gas-solid separation again. The purified gas enters the absorbent liquid in the desulfurization tower 101 through the dispersing head 212 via the connecting pipe 211. The gas is dispersed from the dispersing head 212 into the absorbent liquid inside the desulfurization tower 101, where the absorbent liquid desulfurizes the dispersed gas, making the desulfurization more thorough. The gas is then transported upwards, and the pump 302 connects the connecting box 301 and the inside of the desulfurization tower 101. The absorbent liquid is drawn in and sprayed out from the nozzle 309 through the delivery pipe 303, fixed pipe 305, annular pipe 306, and flexible hose 308. The motor 414 is turned on, causing the circular plate 415 and cylinder 416 to rotate. The cylinder 416 drives the moving frame 412 and moving column 417 to reciprocate. The moving column 417 drives the adjusting frame 418 to reciprocate. The adjusting frame 418 drives the control column 419 and circular frame 421 to rotate reciprocally at a certain angle. The two sets of adjustment mechanisms on the circular frame 421... The groove 422 drives several adjusting rods 423 and the concave frame 406 to move back and forth alternately. The strip groove 407 on the concave frame 406 drives the adjusting column 404 and the connecting bar 403 to swing back and forth in an arc, which drives the rotating shaft 402 and the nozzle 309 to swing. The two sets of nozzles 309 swing in an arc alternately. The absorbent liquid sprayed by the nozzles 309 is evenly and comprehensively sprayed into the gas to fully absorb the sulfur dioxide in the gas, further ensuring the quality of waste gas treatment and protecting the atmospheric environment.
