[0002] With the rapid development of industrialization, waste gas emissions generated in industrial production processes have become one of the main sources of environmental pollution. In order to effectively reduce the pollution of industrial waste gas to the environment, various types of industrial waste gas dust removal devices have emerged and become an important technical means in the field of environmental protection. However, in the existing technology, although industrial waste gas dust removal devices can remove particulate matter in waste gas to a certain extent, there are still some problems in the actual application process, especially in the cleaning of the filter element.

[0003] Existing industrial waste gas dust removal devices are usually equipped with a cleaning mechanism for cleaning the filter element. However, in the prior art, the cleaning method for the filter element mostly adopts a unified and indiscriminate cleaning strategy, that is, regardless of the distribution of impurities on the filter element, the same cleaning measures are taken. However, in the actual working process, due to the characteristics of the exhaust gas flow, it often leads to a large accumulation of impurities at the filter element position corresponding to the intake pipe. If these areas are not cleaned in a focused manner, it will not only affect the cleaning effect of the filter element, but also affect the dust removal efficiency. Summary of the invention

[0020] As a preferred embodiment of the industrial waste gas dust removal device described in the present invention, the water supply mechanism includes a water supply tank, the top of the water supply tank is fixedly connected to a water supply pipe, the bottom end of the water supply pipe extends to the bottom of the water supply tank, a water pump is installed on the water supply pipe and the top of the water supply tank, the top of the water supply pipe is fixedly connected to a hose, and the end of the hose away from the water supply pipe is fixedly connected to the top of the lifting water pipe.

[0021] The dust removal method using the above industrial waste gas dust removal device comprises the following steps:

[0022] Step 1: When performing exhaust gas dust removal, the exhaust gas is introduced into the dust removal box through the air inlet pipe, and then filtered through the filter element and discharged through the exhaust pipe;

[0023] Step 2: When the filter element needs to be cleaned, start the water pump and the drive motor; when the water pump is running, the cleaning liquid in the water supply tank can be introduced into the water supply pipe, and then enters the hose from the water supply pipe, enters the lifting water pipe from the hose, enters the annular water pipe from the lifting water pipe, and finally sprays to the filter element from a plurality of nozzles to flush the filter element; when the drive motor is running, it drives the double-groove pulley to rotate, and the double-groove pulley drives the first single-groove pulley and the second single-groove pulley to rotate synchronously through the belt, and the first single-groove pulley and the second single-groove pulley drive a pair of screws to rotate at the same time, so that the lifting pipe moves downward along the top of the dust removal box and the screw, and the lifting pipe drives the telescopic mechanism to move downward, and the telescopic mechanism drives the annular water pipe and a plurality of nozzles to move downward through the connecting block, which can be moved for flushing, and the flushing range is wide;

[0024] Step 3: In the process of driving the telescopic mechanism downward through the lifting tube, when the lower surface of the protrusion in the telescopic mechanism contacts the upper surface of the outer end of the moving rod for the first time, it indicates that the nozzle has entered the area where more impurities have accumulated in the filter element. At this time, when the fixed block in the telescopic mechanism continues to move downward through the lifting tube, due to the contact between the lower surface of the bottom protrusion and the upper surface of the outer end of the moving rod and the elastic force of the second spring, the telescopic rod and the limit plate will not move downward with the fixed block. When the fixed block moves downward, the first spring is gradually compressed, thereby extending the flushing time of the nozzle in the area where more impurities have accumulated. When the limit plate and the bottom of the positioning plate When the contact is made, at this time, when the fixed block continues to move downward through the lifting tube, the limit plate applies a pressing force to the telescopic rod under the push of the positioning plate, and the telescopic rod applies a pressing force to the protrusion through the vertical rod. The protrusion pushes the moving rod to squeeze the second spring and move toward the inside of the fixed sleeve through the inclined surface of the lower surface and the inclined surface of the upper surface of the moving rod. The lowermost protrusion can move downward through the outer end of the moving rod. When the lowest end protrusion passes through the moving rod, the limit plate moves downward and resets under the action of the rebound force of the first spring and its own gravity. In the process of the lowest end protrusion being reset through the moving rod and the limit plate, the sprinkler moves downward accordingly to change the spraying position.

[0025] After the limit plate is reset, the moving rod also moves and resets under the action of the rebound force of the second spring. After the moving rod is reset, the upper surface slope of the outer end of the moving rod fits with the lower surface slope of the second to last protrusion, and then the fixed block is driven downward by the lifting tube. The above process is repeated. When the top protrusion passes through the moving rod, the nozzle leaves the area where more impurities accumulate in the filter element, and then the fixed block is driven downward by the lifting tube. The fixed block drives the annular water pipe and the nozzle to move downward synchronously through the limit plate and the telescopic rod for flushing. The waste water generated during the flushing process is discharged through the drain pipe.

[0026] Step 4: After the flushing is completed and the spray mechanism needs to be moved up and reset, the driving motor drives the double-groove pulley to rotate in the opposite direction to the previous direction, so that the lifting tube drives the fixed block to move upward, and the fixed block drives the limit plate, the telescopic rod spray mechanism, the vertical rod, and the protrusion to move upward. When the inclined surface of the upper surface of the protrusion contacts the inclined surface of the lower surface of the outer end of the moving rod, the fixed block continues to be pulled upward by the lifting tube, and the fixed block pulls the telescopic rod, the vertical rod, and the protrusion to move upward. Under the action of the pulling force, the protrusion squeezes the moving rod and moves the moving rod toward the inside of the fixed sleeve, so that the protrusion can move upward through the moving rod until the spray mechanism is reset, and the driving motor is turned off to complete the entire cleaning process.

[0027] Beneficial effects of the present invention:

[0028] 1. The present invention can flush the filter element through the coordinated use of the spray mechanism and the water supply mechanism. Through the coordinated use of the driving motor, the double-groove pulley, the first single-groove pulley, the second single-groove pulley, the belt, the screw, the lifting tube, the fixed block, the telescopic rod, etc., the spray mechanism can be moved for flushing, and the flushing range is wide, so the filter element can be better cleaned.

[0029] 2. The present invention can extend the flushing time of the nozzle for the area with more impurities accumulated in the filter element when the lifting tube drives the fixed block to move downward by cooperating the inclined surfaces on the upper and lower sides of the protrusion with the inclined surfaces on the upper and lower sides of the outer end of the moving rod, thereby further improving the cleaning effect of the filter element and not easily affecting the dust removal efficiency of the filter element.

[0064] Step 2: When the filter element 201 needs to be cleaned, start the water pump 502-3 and the drive motor 302; when the water pump 502-3 is running, the cleaning liquid in the water supply tank 502-1 can be introduced into the water supply pipe 502-2, and then enters the hose 502-4 from the water supply pipe 502-2, enters the lifting water pipe 501-4 from the hose 502-4, enters the annular water pipe 501-1 from the lifting water pipe 501-4, and finally sprays toward the filter element 201 by a plurality of nozzles 501-3 to rinse the filter element 201; when the drive motor 302 is running, it drives the double groove pulley 30 3 rotates, the double-groove pulley 303 drives the first single-groove pulley 305 and the second single-groove pulley 306 to rotate synchronously through the belt 307, and the first single-groove pulley 305 and the second single-groove pulley 306 drive a pair of screw rods 304 to rotate at the same time, so that the lifting tube 308 moves downward along the top of the dust removal box 101 and the screw rod 304, and the lifting tube 308 drives the telescopic mechanism 401 to move downward, and the telescopic mechanism 401 drives the annular water pipe 501-1 and a plurality of nozzles 501-3 to move downward through the connecting block 501-2, which can be moved for flushing, and the flushing range is wide;

[0065] Step 3: When the lower surface of the protrusion 401-8 in the telescopic mechanism 401 first contacts the upper surface of the outer end of the moving rod 402-2 (such as Figure 7 and Fig.10 ), indicating that the nozzle 501-3 enters the area of ​​the filter element 201 where impurities are accumulated more. At this time, when the fixed block 401-1 in the telescopic mechanism 401 continues to move downward through the lifting tube 308, due to the contact between the lower surface of the bottommost protrusion 401-8 and the upper surface of the outer end of the moving rod 402-2, and the elastic force of the second spring 402-3, the telescopic rod 401-6 and the limiting plate 401-4 will not move downward with the fixed block 401-1. When the fixed block 401-1 moves downward, the first spring 401-5 is gradually compressed, thereby extending the flushing time of the nozzle 501-3 in the area where impurities are accumulated more, improving the cleaning effect of the filter element 201, and not easily affecting the dust removal efficiency of the filter element 201. When the limiting plate 401-4 contacts the bottom of the positioning plate 401-2 (such as Figure 8 and Fig.11), at this time, when the fixed block 401-1 continues to move downward through the lifting tube 308, the limit plate 401-4 applies a pressing force to the telescopic rod 401-6 under the push of the positioning plate 401-2, and the telescopic rod 401-6 applies a pressing force to the protrusion 401-8 through the vertical rod 401-7. The protrusion 401-8 pushes the moving rod 402-2 to squeeze the second spring 402-3 through the inclined surface of the lower surface and the inclined surface of the upper surface of the moving rod 402-2, and moves toward the inside of the fixed sleeve 402-1, so that the bottom end protrusion 401-8 can move downward through the outer end of the moving rod 402-2. When the lowest end protrusion 401-8 passes through the moving rod 402-2, the limit plate 401-4 moves downward and resets under the rebound force of the first spring 401-5 and its own gravity (such as Fig. 9 and Fig.12 ), when the lowest end protrusion 401-8 is reset by the moving rod 402-2 and the limiting plate 402-2, the nozzle 501-3 moves downward to change the spraying position;

[0066] After the limit plate 401-4 is reset, the moving rod 402-2 is also moved and reset under the action of the rebound force of the second spring 402-3. After the moving rod 402-2 is reset, the upper surface of the outer end of the moving rod 402-2 is in contact with the lower surface of the penultimate protrusion 401-8 (such as Fig.12 ), and then continue to drive the fixed block 401-1 to move downward through the lifting tube 308, repeat the above process, when the topmost protrusion 401-8 passes through the moving rod 402-2, the nozzle 501-3 leaves the area where more impurities accumulate in the filter element 201, and then continue to drive the fixed block 401-1 to move downward through the lifting tube 308, and the fixed block 401-1 drives the annular water pipe 501-1 and the nozzle 501-3 to move downward for flushing through the limit plate 401-4 and the telescopic rod 401-6, and the waste water generated during the flushing process is discharged through the drain pipe 102;

[0067] Step 4: After the flushing is finished, when the spray mechanism 501 needs to be moved up and reset, the double-groove pulley 303 is driven by the driving motor 302 to rotate in the opposite direction to the previous direction, so that the lifting tube 308 drives the fixed block 401-1 to move upward, and the fixed block 401-1 drives the limit plate 401-4, the telescopic rod 401-6, the spray mechanism 501, the vertical rod 401-7, and the protrusion 401-8 to move upward. When the upper surface of the protrusion 401-8 contacts the lower surface of the outer end of the moving rod 402-2, the lifting tube 308 drives the fixed block 401-1 to move upward. The fixed block 401-1 is then pulled upward by the lifting tube 308, and the fixed block 401-1 pulls the telescopic rod 401-6, the vertical rod 401-7, and the protrusion 401-8 upward. Under the action of the pulling force, the protrusion 401-8 squeezes the moving rod 402-2 and moves the moving rod 402-2 toward the inside of the fixed sleeve 402-1, so that the protrusion 401-8 can move upward through the moving rod 402-2 until the spray mechanism 501 is reset, the drive motor 302 is turned off, and the entire cleaning process is completed.
