Description

Technical Field

[0001] The invention relates to the technical field of industrial waste gas dust removal, and in particular to an industrial waste gas dust removal device and method. Background Art

[0002] With the acceleration of industrialization, the problem of industrial waste gas emissions has become increasingly serious and has become one of the main sources of environmental pollution. Industrial waste gas often contains a large amount of solid particles and harmful substances. If these substances are directly discharged into the atmosphere without effective treatment, they will cause serious pollution to the environment and affect the ecological balance and human health. Therefore, efficient dust removal of industrial waste gas has become an important issue that needs to be solved in the field of environmental protection.

[0003] In the existing industrial waste gas dust removal technology, filter dust removal is a common and widely used method. This method intercepts solid particles in the exhaust gas through the filter to achieve the purpose of dust removal. However, in actual use, there are some significant problems with the filter dust removal device. First, as the running time increases, a large amount of dust will accumulate on the filter, affecting the dust removal efficiency. In order to keep the filter clean and the dust removal effect, the filter needs to be cleaned regularly. Some technologies try to use dust suction to clean the filter. This method uses the principle of negative pressure dust suction to suck the dust on the filter into the dust collection device. However, in actual applications, the dust suction method also faces some challenges. Since the dust in industrial waste gas often has a certain degree of adhesion, it is difficult to effectively remove the dust on the filter through the dust suction device, resulting in poor cleaning effect.

The air blowing hood is provided with an air blowing port on the side away from the horizontal pipe, and an air inlet is provided on the top of the air blowing hood. A dust shield is fixedly connected to the edge of the side of the air blowing hood away from the horizontal pipe, and the dust shield is arranged above the air inlet. Opening and closing parts are provided in the air blowing port and the air inlet. When blowing, the opening and closing part in the air blowing port is opened, and the opening and closing part in the air inlet is closed. When inhaling, the opening and closing part in the air inlet is opened, and the opening and closing part in the air blowing port is closed.

[0021] As a preferred solution of the industrial waste gas dust removal device of the present invention, wherein: the opening and closing member includes a fixed ring fixedly connected to the inner wall of the air blowing port and the air inlet and a plurality of movable leaves rotatably connected to one side of the fixed ring, the plurality of movable leaves are fixedly connected to the air blowing port and the air inlet by springs, and in a natural state, the plurality of movable leaves can form a closed state under the elastic force of the spring, the movable leaves in the air blowing port are arranged in the direction of the fixed ring toward the outer end of the blowing port, and the movable leaves in the air inlet are arranged in the direction of the fixed ring toward the inner end of the air inlet;

[0023] The dust removal method using the above industrial waste gas dust removal device comprises the following steps:

[0024] Step 1: When in use, the industrial waste gas is introduced into the dust removal box through the air inlet pipe, and the industrial waste gas is filtered through the filter mesh tube to remove the dust in the industrial waste gas and then discharged through the air outlet pipe;

[0025] Step 2: When it is necessary to clean the dust on the outer surface of the filter mesh tube, first, start the dual-axis motor and the suction pump. When the suction pump is running, negative pressure can be formed at the suction end of the suction pump, so that gas can be drawn into the dust suction pipe through the hose, and then the dust on the filter mesh tube can be sucked away through the dust suction cover. When the dual-axis motor is running, it can drive the driving gear and the sliding sleeve to rotate, and the sliding sleeve drives the filter mesh tube to rotate through the lower cover, so that the surrounding side of the filter mesh tube can be cleaned;

[0026] Step 3: When the driven gear rotates, the lead screw rotates accordingly, and the lifting plate can move downward along the lead screw under the guidance and limiting action of the guide slide bar, and the lifting plate drives the dust suction pipe to move downward, and the dust suction pipe drives the dust suction cover to move downward, so that the filter plate can be moved and cleaned;

[0027] Step 4: When the dust suction pipe moves downward, the connecting rod can be driven to move downward through the fixed rod, the connecting rod drives the horizontal pipe to move downward, and the horizontal pipe drives the air blowing head to move downward, so as to ensure that the air blowing head and the dust hood always correspond to each other. In addition, when the horizontal pipe moves downward, it can also drive the vertical pipe to move downward along the piston rod. Through the squeezing effect of the piston rod, the air pressure inside the vertical pipe and the horizontal pipe increases, so as to open the movable leaf in the air blowing port. The gas is blown to the filter mesh tube through the movable leaf, and the dust on the filter mesh tube can be blown to the dust hood, so as to assist the dust hood in absorbing dust.

[0028] Step 5: After the cleaning is completed, when the lifting plate needs to be moved upward to reset, turn off the suction pump, and then use the dual-axis motor to drive the driving gear to rotate in the opposite direction to the previous direction, so that the lifting plate can move upward along the screw rod, and the lifting plate drives the dust hood and the fixed rod to move upward through the dust suction pipe. The fixed rod drives the horizontal pipe, the blowing head and the vertical pipe upward through the connecting rod. When the vertical pipe moves upward along the piston rod, the air pressure inside the vertical pipe and the horizontal pipe becomes smaller. Therefore, the gas in the filter mesh pipe rushes open the movable leaf in the air inlet and enters the horizontal pipe and the vertical pipe. In addition, by setting a dust cover, the dust on the filter mesh pipe can be prevented from being sucked into the inside of the horizontal pipe.

[0029] Beneficial effects of the present invention:

[0030] 1. The present invention drives the filter mesh tube and the driving gear to rotate at the same time through a dual-axis motor. The driving gear drives the screw rod to rotate through the driven gear, so that the lifting plate can move downward. The lifting plate drives the dust cover to move downward through the dust suction pipe, so that the filter mesh tube can be cleaned in all directions, with a wide cleaning range and good cleaning effect.

[0031] 2. The present invention can ensure that the air blowing head always corresponds to the dust hood through the coordinated use of a fixing rod, a connecting rod, etc. In addition, through the coordinated use of a vertical pipe, a piston rod, etc., the air blowing head can generate a blowing force, which can blow the dust on the filter mesh tube toward the dust hood, thereby helping the dust hood to absorb the dust, preventing the dust from adhering to the filter mesh tube, making it difficult for the dust hood to be sucked away, and thus improving the cleaning effect of the filter mesh tube.

[0032] 3. In the present invention, by arranging opening and closing parts in the air blowing port and the air inlet, the air inlet and outlet of the air blowing head are not in the same direction, and when used in conjunction with the dust cover, when the vertical pipe moves upward to generate suction, dust can be prevented from entering the horizontal pipe through the air inlet.

The top of the sliding sleeve 307 is fixedly connected to the center of the bottom of the lower cover 203 by bolts. The inner bottom wall of the sliding sleeve 307 is fixedly connected with a piston rod 308. The top of the screw rod 304 is rotatably inserted into the top of the dust removal flocculus box 100 and is rotatably connected with the inner top wall of the dust removal flocculus box 100. The guide slide bar 305 and the screw rod 304 are respectively arranged on the left and right sides of the filter mesh tube 201.

[0060] Specifically, Figure 5-6 The dust collection unit 400 includes a bracket 401 fixedly connected to the top of the dust removal flocculant box 100, an air suction pump 402 and a dust collection box 403 fixedly connected to the top of the bracket 401 by bolts, a three-way joint fixedly connected to the air suction end of the air suction pump 402, two connecting hoses 404 fixedly connected to the three-way joint, a pair of dust collection pipes 405 fixedly connected to one end of the two connecting hoses 404 away from the three-way joint, and a dust collection cover 406 fixedly connected to one end of the pair of dust collection pipes 405 away from the connecting hose 404;

[0061] The air outlet end of the suction pump 402 is fixedly connected to the dust collecting box 403, and an air outlet groove is provided on one side of the dust collecting box 403.

The dust suction hood 405 is correspondingly arranged with the filter mesh tube 201, and the dust blowing unit 500 is fixedly connected to the dust suction pipe 404.

[0062] When in use, start the suction pump 402. When the suction pump 402 is running, negative pressure can be formed at the suction end of the suction pump 402, so that gas can be drawn into the dust suction pipe 405 through the hose 404, and then the dust on the filter mesh tube 201 can be sucked away through the dust suction hood 406, thereby achieving a cleaning effect.

[0064] The top end of the connecting rod 504 movably passes through the air outlet pipe 102 and is fixedly connected to a fixing rod 505. The two ends of the fixing rod 505 are respectively fixedly connected to a pair of dust suction pipes 405.

[0066] Example 2

[0067] Reference Figure 9-10, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the air blowing head 502 includes a pair of air blowing hoods 502-1 respectively fixedly connected to the two ends of the transverse tube 501, and the pair of air blowing hoods 502-1 are respectively arranged corresponding to a pair of dust suction hoods 406. The air blowing hood 502-1 is provided with an air blowing port 502-2 on the side away from the transverse tube 501, and an air inlet 502-3 is provided on the top of the air blowing hood 502-1. A dust shield 502-5 is fixedly connected to the edge of the side of the air blowing hood 502-1 away from the transverse tube 501, and the dust shield 502-5 is provided on the air inlet 502-3. Above, the advantage of such a configuration is that it can block the gas close to the inner wall of the filter mesh tube 201 from being sucked into the air inlet 502-3, thereby preventing the dust on the filter mesh tube 201 from being sucked into the air inlet 502-3. The air blowing port 502-2 and the air inlet 502-3 are both provided with an opening and closing member 502-4. When blowing, the opening and closing member 502-4 in the air blowing port 502-2 is opened, while the opening and closing member 502-4 in the air inlet 502-3 is closed. When inletting, the opening and closing member 502-4 in the air inlet 502-3 is opened, while the opening and closing member 502-4 in the air blowing port 502-2 is closed.

[0068] The opening and closing member 502-4 includes a fixed ring 502-41 fixedly connected to the inner walls of the blowing port 502-2 and the air inlet 502-3, and a plurality of movable leaves 502-42 rotatably connected to one side of the fixed ring 502-41. The plurality of movable leaves 502-42 are fixedly connected to the blowing port 502-2 and the air inlet 502-3 by springs 502-43, and in a natural state, the plurality of movable leaves 502-42 can form a closed state under the elastic force of the springs 502-43. The movable leaves 502-42 in the blowing port 502-2 are arranged in the direction of the fixed ring 502-41 toward the outer end of the blowing port 502-2, and the movable leaves 502-42 in the air inlet 502-3 are arranged in the direction of the fixed ring 502-41 toward the inner end of the air inlet 502-3;

[0069] When blowing, several movable leaves 502-42 in the blowing port 502-2 open under stress, while several movable leaves 502-41 in the air inlet 502-3 continue to remain closed under stress; when inhaling, several movable leaves 502-41 in the air inlet 502-3 open under stress, while several movable leaves 502-42 in the blowing port 502-2 continue to remain closed under stress.

[0070] The remaining structures are the same as those of Example 1.

[0071] During use, when cleaning is completed and the lifting plate 306 needs to be moved upward and reset, the suction pump 402 is turned off, and then the dual-axis motor 301 drives the driving gear 302 to rotate in the opposite direction to the previous direction, so that the lifting plate 306 can move upward along the screw rod 304, and the lifting plate 306 drives the dust cover 406 and the fixed rod 505 to move upward through the dust suction pipe 405, and the fixed rod 505 drives the horizontal pipe 501, the blowing head 502 and the vertical pipe 503 to move upward through the connecting rod 504. When the vertical pipe 503 moves upward along the piston rod 308, the air pressure inside the vertical pipe 503 and the horizontal pipe 501 becomes smaller. Therefore, the gas in the filter mesh tube 201 rushes through the movable leaf 502-42 in the air inlet 502-3 and enters the horizontal pipe 501 and the vertical pipe 503. In addition, by setting the dust cover 502-5, it is possible to prevent the dust on the filter mesh tube 201 from being sucked into the horizontal pipe 501.

[0072] The dust removal method using the above industrial waste gas dust removal device comprises the following steps:

[0073] Step 1: When in use, the industrial waste gas is introduced into the dust removal box 100 through the air inlet pipe 101, and the industrial waste gas is filtered out through the filter mesh pipe 201 to remove the dust in the industrial waste gas and then discharged through the air outlet pipe 102;

[0074] Step 2: When it is necessary to clean the dust on the outer surface of the filter mesh tube 201, first, start the dual-axis motor 301 and the air suction pump 402. When the air suction pump 402 is running, negative pressure can be formed at the air suction end of the air suction pump 402, so that gas can be drawn into the dust suction pipe 405 through the hose 404, and then the dust on the filter mesh tube 201 can be sucked away through the dust suction cover 406. When the dual-axis motor 301 is running, it can drive the driving gear 302 and the sliding sleeve 307 to rotate, and the sliding sleeve 307 drives the filter mesh tube 201 to rotate through the lower cover 203, so that the surrounding side of the filter mesh tube 201 can be cleaned;

[0075] Step 3: When the driven gear 303 rotates, the screw rod 304 rotates accordingly, and the lifting plate 306 can move downward along the screw rod 304 under the guidance and limiting action of the guide slide bar 305, and the lifting plate 306 drives the dust suction pipe 405 to move downward, and the dust suction pipe 405 drives the dust suction cover 406 to move downward, so that the filter plate 201 can be moved and cleaned;

[0076] Step 4: When the dust suction pipe 405 moves downward, the fixing rod 505 can drive the connecting rod 504 to move downward, the connecting rod 504 drives the horizontal pipe 501 to move downward, and the horizontal pipe 501 drives the blowing head 502 to move downward, so as to ensure that the blowing head 502 and the dust hood 406 always correspond to each other. In addition, when the horizontal pipe 501 moves downward, it can also drive the vertical pipe 503 to move downward along the piston rod 308. Through the squeezing effect of the piston rod 308, the internal air pressure of the vertical pipe 503 and the horizontal pipe 501 increases, so as to open the movable leaf 502-42 in the blowing port 502-2, and the gas is blown toward the filter mesh tube 201 through the movable leaf 502-42, so as to blow the dust on the filter mesh tube 201 toward the dust hood 406, so as to assist the dust hood 406 in absorbing dust.

[0077] Step 5: After the cleaning is completed, when the lifting plate 306 needs to be moved upward to reset, the suction pump 402 is turned off, and then the dual-axis motor 301 drives the driving gear 302 to rotate in the opposite direction to the previous direction, so that the lifting plate 306 can move upward along the screw rod 304, and the lifting plate 306 drives the dust cover 406 and the fixed rod 505 to move upward through the dust suction pipe 405, and the fixed rod 505 drives the horizontal pipe 501, the blowing head 502 and the vertical pipe 503 to move upward through the connecting rod 504. When the vertical pipe 503 moves upward along the piston rod 308, the internal air pressure of the vertical pipe 503 and the horizontal pipe 501 becomes smaller. Therefore, the gas in the filter mesh tube 201 rushes open the movable leaf 502-42 in the air inlet 502-3 and enters the horizontal pipe 501 and the vertical pipe 503. In addition, by setting the dust cover 502-5, it can be avoided that the dust on the filter mesh tube 201 is sucked into the horizontal pipe 501.

[0078] It is worth noting that the entire device is controlled by a controller. Since the controller is a commonly used device and belongs to the existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.
