Description

Technical Field

[0001] The invention relates to the technical field of dust waste gas treatment, and in particular to a dust waste gas high-efficiency treatment device and method. Background Art

[0002] Dust refers to solid particles suspended in the air, such as dust, dust, smoke, mineral dust, sand dust, powder, etc. The International Organization for Standardization stipulates that solid suspended matter with a particle size of less than 75μm is defined as dust. The presence of dust in the atmosphere is one of the main reasons for maintaining the earth's temperature. Too much or too little dust in the atmosphere will have a catastrophic impact on the environment. However, in life and work, productive dust is the natural enemy of human health and the main cause of many diseases. Therefore, dust exhaust gas needs to be treated. The Chinese patent with application number 202210227907.6 discloses "an environmental protection treatment device for dust mixed exhaust gas, including a striking mechanism, a driving member drives a ratchet to rotate, and the ratchet drives a gear. The gear 1 drives the swinging member 1 to swing forward, the gear 1 drives the gear 3 to rotate in the opposite direction through the gear 2, the gear 3 drives the swinging member 2 to swing in the opposite direction through the rotating shaft 2, the connecting member abuts against the gear 1 so that the abutting member 2 abuts against the ratchet, the ratchet drives the gear 3 to rotate forward through the connecting member in cooperation with the rotating shaft 2, the gear 3 drives the swinging member 2 to swing forward, and drives the swinging member 1 to swing in the opposite direction through the cooperation of the gear 2 and the gear 1, the swinging member 1 and the swinging member 2 drive the striking assembly to swing back and forth to strike the filter screen, so that the filter screen is evenly stressed, the filtering effect is improved and the filter screen is prevented from being blocked. The present invention can better treat the dust mixed exhaust gas, avoid air pollution, and is more energy-saving and environmentally friendly.

[0003] This technical solution only solves the problem that the filter is easily deformed after being knocked. However, for combustion smoke exhaust gas, the filter alone is not enough to effectively separate the smoke and exhaust gas. Electrostatic precipitators are commonly used in the current smoke exhaust gas treatment to separate the smoke and exhaust gas through a high-voltage electric field. However, for smoke exhaust gas with a faster flow rate, the smoke in the exhaust gas is often not treated cleanly, and the smoke separated in the equipment is easily carried out of the equipment, causing emission pollution.

[0018] The present invention also provides another technical solution: a method for efficiently treating dust and waste gas, comprising the following steps:

[0019] S1. The dust-containing exhaust gas is passed into the electrostatic dust collector through the exhaust gas inlet pipe, and the discharge is performed through the discharge plate, so that the dust in the exhaust gas is adsorbed on the dust collecting plate. When the exhaust gas enters the exhaust gas inlet pipe, the fan blade roller is blown to rotate. When the fan blade roller rotates, a transmission horizontal shaft close to the exhaust gas inlet pipe is driven to rotate through the transmission belt, and then all the transmission horizontal shafts are driven to rotate through the first transmission chain. When the transmission horizontal shaft rotates, the rotating frame is driven to rotate through the engagement of the limit opening and the limit groove. When the rotating frame rotates, it drives the rolling wheel to contact the bottom end of the dust collecting plate and rotate. When the rotating frame drives the knocking wheel to rotate quickly to the bottom end of the dust collecting plate, The knocking wheel knocks the bottom end of the dust collecting plate, so that the dust adsorbed on the dust collecting plate is knocked down, and the knocking wheel rolls along the bottom end of the dust collecting plate after knocking the dust collecting plate, driving the rotating frame to slide on the transmission horizontal axis through the limiting groove, so that the distance between the knocking wheel and the transmission horizontal axis becomes smaller, driving the movable rod to be inserted into the transmission horizontal axis, and causing the spring to be compressed. After the rotating frame rotates to a vertical state, the distance between the knocking wheel and the transmission horizontal axis becomes larger through the elastic force of the spring. Under the continuous and rapid rotation of the transmission horizontal axis, the knocking wheel is driven to continuously knock the dust collecting plate, so that the dust collecting plate maintains the dust adsorption capacity, thereby improving the dust removal capacity of the dust exhaust gas;

[0020] Pour clean water into the water tank so that the clean water level above the filter layer is between the filter layer and the top of the water tank, and the clean water level on the side of the partition close to the electrostatic dust collector is higher than the filter layer. When the dust on the dust collecting plate is knocked off, it falls on the mesh plate, and the dust is dispersed through the mesh plate and falls into the grooves on the collecting plate. After starting the water pump, the clean water above the filter layer is extracted through the suction pipe, and then the extracted clean water is slowly discharged through the holes through the drainage pipe. The discharged clean water drips into the groove of the collecting plate, so that the dust is mixed with the clean water, and then discharged into the water tank through the discharge pipe. The drainage speed of the electrostatic dust collector can be controlled by controlling the switch of the discharge pipe.

[0021] S2. The dust exhaust gas after electrostatic dust removal is discharged into the water tank through the exhaust pipe and enters the water below the filter layer. The exhaust gas removed by the electrostatic dust removal box has a fast flow rate, resulting in incomplete dust removal. The exhaust gas entering the water tank is discharged into the water, so that the dust in the exhaust gas is mixed with the water, so that the dust is isolated in the water tank through the filter layer, and the exhaust gas rises through the filter layer;

[0022] S3, start the dual-axis motor, and drive the connecting plate to rotate up and down reciprocatingly through the dual-axis motor. When the connecting plate rotates downward, it drives the lifting plate to move downward in the exhaust box. At this time, the lower airbag is in the exhaust state, and the upper airbag is in the exhaust state. The air in the lower airbag is discharged into the water tank through the outlet pipe. The second air inlet check valve allows the air in the lower airbag to be discharged only through the air inlet pipe, while the upper airbag extracts the exhaust gas filtered by the filter layer in the water tank through the exhaust pipe, and the first air outlet check valve allows the upper airbag to be exhausted only through the exhaust pipe;

[0023] When the lifting plate moves upward, the lower airbag is in a state of exhausting air, and the upper airbag is in a state of exhausting air. External air is extracted through the air inlet pipe, and the water in the water tank is prevented from entering the lower airbag when the lower airbag is exhausted through the second air outlet one-way valve. The exhaust gas extracted from the upper airbag is discharged through the exhaust pipe, and the exhaust gas can only be discharged through the exhaust pipe through the first air inlet one-way valve;

[0024] S4. When the air outlet pipe passes the outside air into the water tank at a high speed, the turbofan is blown to rotate, and the vertical shaft connected to the turbofan is driven to rotate through the turbofan, and then the transmission gear and the second transmission chain drive all the vertical shafts to rotate, so that the stirring rod on the vertical shaft rotates accordingly, and the water mixed with dust is stirred by the rotating stirring rod, so that the dust and water are fully mixed, and the bubbles discharged from the exhaust pipe are broken up, and the clean water on the orifice plate is extracted by the water pump, and then the water mixed with dust in the electrostatic dust removal box is discharged into the water tank through the discharge pipe, forming a cycle. When too much dust accumulates in the water tank, it is only necessary to discharge the sewage mixed with dust in the water tank.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] The present invention drives the knocking wheel to rotate quickly to the bottom end of the dust collecting plate through the rotating frame, and the knocking wheel knocks the bottom end of the dust collecting plate, so that the dust adsorbed on the dust collecting plate is knocked down, and the knocking wheel continuously knocks the dust collecting plate, so that the dust collecting plate maintains the dust adsorption capacity, and the dust removal capacity of the dust exhaust gas is improved. The clean water discharged through the drain pipe drips into the groove of the collection plate, so that the dust and the clean water are mixed and discharged into the electrostatic dust removal box, so that the electrostatic dust removal mechanism maintains the dust removal capacity, and the dust removal efficiency is improved.

[0027] The present invention passes the exhaust gas in the electrostatic dust collector box, which is not completely dust-removed due to its fast flow rate, into the water tank through the exhaust gas outlet pipe, so that the dust in the exhaust gas is mixed with water, and the dust is isolated in the water tank through the filter layer, while the exhaust gas rises through the filter layer, thereby further improving the dust removal efficiency of the dust and exhaust gas, and the filtered exhaust gas in the water tank is extracted and discharged through the upper air bag, and the outside air is passed into the water mixed with dust in the water tank through the lower air bag, and the turbofan is blown to drive the vertical axis to rotate, so that the dust and water are fully mixed, and the bubbles discharged from the exhaust gas outlet pipe are broken up, and the clean water on the orifice plate is extracted by the water pump, and the water mixed with dust in the electrostatic dust collector box is discharged into the water tank through the discharge pipe, forming a cycle, thereby improving the dust removal efficiency.

[0050] The present invention also provides another technical solution: a method for efficiently treating dust and waste gas, comprising the following steps:

[0051] S1. The dust-containing exhaust gas is passed into the electrostatic dust collector box 201 through the exhaust gas inlet pipe 1, and the discharge is carried out through the discharge plate 205, so that the dust in the exhaust gas is adsorbed on the dust collecting plate 204. When the exhaust gas enters the exhaust gas inlet pipe 1, the fan blade roller 206 is blown to rotate. When the fan blade roller 206 rotates, a transmission horizontal shaft 207 close to the exhaust gas inlet pipe 1 is driven to rotate through the transmission belt 216, and then all the transmission horizontal shafts 207 are driven to rotate through the first transmission chain 208. When the transmission horizontal shaft 207 rotates, the rotating frame 210 is driven to rotate through the engagement of the limit opening 209 and the limit groove 211. When the rotating frame 210 rotates, it drives the rolling wheel 213 to contact the bottom end of the dust collecting plate 204 and rotate. When the rotating frame 210 drives the knocking wheel 212 to rotate quickly to the bottom end of the dust collecting plate 204, the knocking wheel 212 knocks the bottom end of the dust collecting plate 204, so that the dust adsorbed on the dust collecting plate 204 is knocked down, and the knocking wheel 212 rolls along the bottom end of the dust collecting plate 204 after knocking the dust collecting plate 204, driving the rotating frame 210 to slide on the transmission horizontal shaft 207 through the limiting groove 211, so that the distance between the knocking wheel 212 and the transmission horizontal shaft 207 becomes smaller, driving the movable rod 214 to be inserted into the transmission horizontal shaft 207, and causing the spring 215 to be compressed. After the rotating frame 210 rotates to a vertical state, the elastic force of the spring 215 causes the distance between the knocking wheel 212 and the transmission horizontal shaft 207 to become larger. Under the continuous and rapid rotation of the transmission horizontal shaft 207, the knocking wheel 212 can be driven to continuously knock the dust collecting plate 204, so that the dust collecting plate 204 maintains the dust adsorption capacity, thereby improving the dust removal capacity of the dust exhaust gas;

[0052] Clean water is poured into the water tank 301, so that the clean water level above the filter layer 402 is located between the filter layer 402 and the top of the water tank 301, and the clean water level on the side of the partition close to the electrostatic dust removal box 201 is higher than the filter layer 402. When the dust on the dust collecting plate 204 is knocked off, it falls on the mesh plate 305, and the dust is dispersed through the mesh plate 305 and dispersed into the grooves on the collecting plate 306. After starting the water pump 302, the clean water above the filter layer 402 is extracted through the water pump 303, and then the extracted clean water is slowly discharged through the holes through the drain pipe 304. The discharged clean water drips into the groove of the collecting plate 306, so that the dust is mixed with the clean water, and then discharged into the water tank 301 through the discharge pipe 307. The drainage speed of the electrostatic dust removal box 201 can be controlled by controlling the switch of the discharge pipe 307.

[0053] S2. The dust exhaust gas after electrostatic dust removal is discharged into the water tank 301 through the exhaust pipe 202 and enters the water below the filter layer 402. The exhaust gas after dust removal by the electrostatic dust removal box 201 has a fast flow rate, resulting in incomplete dust removal. The exhaust gas entering the water tank 301 is discharged into the water, so that the dust in the exhaust gas is mixed with the water, so that the dust is isolated in the water tank 301 through the filter layer 402, and the exhaust gas rises through the filter layer 402;

[0054] S3, start the dual-axis motor 504, and drive the connecting plate 505 to rotate up and down reciprocatingly through the dual-axis motor 504. When the connecting plate 505 rotates downward, it drives the lifting plate 503 to move downward in the exhaust box 501. At this time, the lower airbag 512 is in the exhaust state, and the upper airbag 507 is in the exhaust state. The air in the lower airbag 512 is discharged into the water tank 301 through the air outlet pipe 515. The air in the lower airbag 512 can only be discharged through the air inlet pipe 513 through the second air inlet check valve 514, and the upper airbag 507 extracts the exhaust gas filtered by the filter layer 402 in the water tank 301 through the exhaust pipe 510, and the upper airbag 507 can only be exhausted through the exhaust pipe 510 through the first air outlet check valve 509;

[0055] When the lifting plate 503 moves upward, the lower airbag 512 is in a vacuum state, and the upper airbag 507 is in a vacuum state. External air is extracted through the air inlet pipe 513, and the water in the water tank 301 does not enter the lower airbag 512 when the lower airbag 512 is vacuumed through the second air outlet one-way valve 516. The exhaust gas extracted from the upper airbag 507 is discharged through the exhaust pipe 508, and the exhaust gas can only be discharged through the exhaust pipe 508 through the first air inlet one-way valve 511.

[0056] S4. When the air outlet pipe 515 passes the outside air into the water tank 301 at a high speed, the turbofan 407 is blown to rotate, and the vertical shaft 403 connected to the turbofan 407 is driven to rotate through the turbofan 407, and then the transmission gear 405 and the second transmission chain 406 drive all the vertical shafts 403 to rotate, so that the stirring rod 404 on the vertical shaft 403 rotates accordingly, and the water mixed with dust is stirred by the rotating stirring rod 404, so that the dust and water are fully mixed, and the bubbles discharged from the exhaust pipe 202 are broken up, and the clean water on the orifice plate 401 is extracted by the water pump 302, and then the water mixed with dust in the electrostatic dust removal box 201 is discharged into the water tank 301 through the discharge pipe 307, forming a cycle. When too much dust accumulates in the water tank 301, it is only necessary to discharge the sewage mixed with dust in the water tank 301.

The dust-containing waste gas is introduced into the electrostatic dust removal box (201) through the waste gas inlet pipe (1), and the discharge is performed through the discharge plate (205), so that the dust in the waste gas is adsorbed on the dust collecting plate (204). When the waste gas enters the waste gas inlet pipe (1), the fan blade roller (206) is driven to rotate. When the fan blade roller (206) rotates, a transmission horizontal shaft (207) close to the waste gas inlet pipe (1) is driven to rotate through the transmission belt (216), and then the first transmission The chain (208) drives all the transmission transverse shafts (207) to rotate. When the transmission transverse shaft (207) rotates, the engagement of the limit opening (209) and the limit groove (211) drives the rotating frame (210) to rotate. When the rotating frame (210) rotates, the rolling wheel (213) is driven to contact the bottom end of the dust collecting plate (204) and rotate. When the rotating frame (210) drives the knocking wheel (212) to rotate quickly to the bottom end of the dust collecting plate (204), the knocking wheel The knocking wheel (212) knocks the bottom end of the dust collecting plate (204), so that the dust adsorbed on the dust collecting plate (204) is knocked down, and the knocking wheel (212) rolls along the bottom end of the dust collecting plate (204) after knocking the dust collecting plate (204), driving the rotating frame (210) to slide on the transmission horizontal shaft (207) through the limiting groove (211), so that the distance between the knocking wheel (212) and the transmission horizontal shaft (207) becomes smaller, driving the movable rod (214) to insert into the transmission horizontal shaft The rotating frame (210) is rotated to a vertical state, and the spring (215) is compressed. The elastic force of the spring (215) increases the distance between the knocking wheel (212) and the transmission horizontal axis (207).

At this time, the lower air bag (512) is in an exhaust state, and the upper air bag (507) is in an exhaust state. The air in the lower air bag (512) is discharged into the water tank (301) through the air outlet pipe (515).

External air is drawn in through the air intake pipe (513), and the water in the water tank (301) does not enter the lower airbag (512) when the lower airbag (512) is suctioned through the second air outlet one-way valve (516). The exhaust gas drawn in the upper airbag (507) is discharged through the exhaust pipe (508), and the exhaust gas can only be discharged through the exhaust pipe (508) through the first air intake one-way valve (511); S4. When the air outlet pipe (515) passes the outside air into the water tank (301) at a high speed, the turbofan (407) is driven to rotate, and the vertical shaft (403) connected to the turbofan (407) is driven to rotate through the turbofan (407), and then the entire vertical shaft (403) is driven to rotate through the transmission gear (405) and the second transmission chain (406), so that the stirring rod (404) on the vertical shaft (403) rotates accordingly, and the rotating stirring rod (404) is used to rotate the vertical shaft (403). The water mixed with dust is stirred so that the dust and water are fully mixed, and the bubbles discharged from the exhaust pipe (202) are dispersed, and clean water on the orifice plate (401) is extracted by a water pump (302), and then the water mixed with dust in the electrostatic dust removal box (201) is discharged into the water tank (301) through a discharge pipe (307), forming a cycle. When too much dust accumulates in the water tank (301), it is only necessary to discharge the wastewater mixed with dust in the water tank (301).
