Description
Technical Field
[0001] The invention relates to the technical field of pulse dust collectors, in particular to a dust collector with an anti-condensation function. Background Art
[0002] As a highly efficient dry-type filtration and dust removal equipment widely used in the field of industrial dust control, the working principle of bag dust collector is based on a specific physical mechanism. After the dust-laden gas flows into the dust collector from the air inlet, the dust particles are adsorbed on the outer surface of the filter bag due to inertial collision, interception and diffusion in the process of passing through the filter bag. The filter bag is generally made of fiber material through a weaving process. The gaps between the fibers form a complex filtration channel. This structure provides a key condition for the retention of dust.
[0003] As the filtering process continues, the dust layer on the surface of the filter bag continues to accumulate and thicken, causing the dust collector's operating resistance to gradually increase. When the resistance climbs to a certain threshold, it is necessary to carry out dust cleaning operations. Pulse jet cleaning technology plays a key role here. Compressed air is sprayed into the filter bag at an instantaneous high speed through the small holes on the spray pipe, causing the filter bag to expand rapidly. The shock wave generated by this expansion causes the dust layer on the surface of the filter bag to fall off and then fall into the ash hopper. In the actual operation of the bag filter, condensation is an important issue that cannot be ignored. Once condensation occurs, it is very likely to cause a series of negative effects, such as dust agglomeration, filter bag clogging, and equipment corrosion. These problems will seriously affect the dust removal efficiency of the bag filter, the service life of the filter bag, and the overall stability and reliability of the equipment. Summary of the invention
[0004] The object of the present invention is to provide a dust collector with an anti-condensation function to solve the problems in the prior art.

[0006] The present invention discloses a dry-type filtering dust removal equipment applied to industrial production. When the vacuum pump is started, the dust-containing gas is sucked into the box body through the air inlet pipe. The dust-containing gas first passes through the dehumidification mechanism to discharge the water in the gas and then passes into the filtering mechanism to prevent the water-containing dust from condensing and adhering to the fiber filter bag. When the dust passes through the fiber filter bag, it is adsorbed on the outer surface of the fiber filter bag due to inertial collision, interception, diffusion and the like. The clean gas passes through the fiber filter bag and is sucked out by the vacuum pump through the air outlet. As the filtering process continues, the dust layer on the surface of the fiber filter bag continues to thicken, resulting in a gradual increase in the resistance of the dust collector. The pulse mechanism sprays compressed air through the air distribution pipe at a high speed into the interior of the fiber filter bag instantly, causing it to expand rapidly. The shock wave generated causes the dust layer on the surface of the fiber filter bag to fall off and fall into the lower hopper. The dehumidification mechanism sprays the recovered water on the inner wall of the lower hopper to cause the falling dust to agglomerate, thereby improving the filtering effect for internal self-cleaning.
[0007] Furthermore, the dehumidification mechanism also includes a centrifugal mechanism, an annular shell, a reciprocating mechanism and a filtrate ring. The centrifugal mechanism includes a chassis and an outer arc shell. The annular shell includes a shell and a second one-way valve. The reciprocating mechanism includes a right-angle rod and a concave ring. The chassis and the outer arc shell are fixedly connected to the assembly rod, the shell is fixedly connected to the outer arc shell, the filtrate ring is fixedly connected to the chassis, a liquid collecting slope and a sliding hole are provided on the shell, the right-angle rod is slidably connected to the sliding hole, the concave ring is slidably connected to the shell, a liquid leakage groove and a ejector pin are provided on the concave ring, the liquid collecting slope is in contact with the liquid leakage groove, and the second one-way valve is in contact with the ejector pin.
[0008] The vacuum pump is started to draw the dust-containing gas into the box through the air inlet pipe. The dust-containing gas is drawn to the bottom of the chassis. Under the action of the centrifugal mechanism, the gas is thrown to the filtrate ring, and the dry dust-containing gas passes upward. The moisture in the gas is collected by the filtrate ring and leaks into the reciprocating mechanism through the leakage groove and the liquid collecting slope. The reciprocating mechanism continuously pumps air into the ring shell through the second one-way valve, and finally sprays the collected moisture onto the inner wall of the lower hopper.
[0009] Furthermore, the centrifugal mechanism also includes a drive motor, an impeller and an upper arc cover. The drive motor and the upper arc cover are fixedly connected to the chassis, the output end of the drive motor is fixedly connected to the impeller, the upper arc cover and the outer arc shell form an air outlet, and the reciprocating mechanism also includes a threaded rod, which is fixedly connected to the impeller.

The impeller rotates at high speed to throw the gas to the inner wall of the filtrate ring. The moisture in the gas is collected by the filtrate ring and leaks into the ring shell through the leakage groove and the liquid collecting slope. The dry dust-containing gas bypasses the filtrate ring and passes upward through the outlet duct between the upper arc cover and the outer arc shell.
[0011] Furthermore, the annular shell also includes a first one-way valve, a liquid return groove, an air return groove, a first through hole and a second through hole are provided on the shell, the first one-way valve, the second one-way valve, the first through hole and the second through hole are each provided with several groups, and the several groups of the first one-way valve, the second one-way valve, the first through hole and the second through hole are evenly distributed along the circumference of the shell, the liquid return groove and the first through hole are provided on the outer wall of the shell, the air return groove is provided on the inner wall of the shell, the air return groove is provided below the liquid return groove, the liquid collecting slope is provided above the liquid return groove, the first one-way valve is fixedly connected to the first through hole, and the second one-way valve is fixedly connected to the second through hole.
[0012] When the concave ring is located at the upper end of the shell, the moisture in the gas is collected by the filtrate ring and leaks into the concave ring through the leakage groove and the liquid collecting slope. The ejector pin contacts and pushes open the second one-way valve, allowing external air to enter the concave ring. The reciprocating mechanism drives the concave ring to move downward, and the collected moisture liquid first enters the shell through the return liquid groove, and then the gas in the concave ring enters the shell through the return gas groove. When the concave ring moves downward, it squeezes the space below the shell, and the moisture and gas in the space on the lower side of the shell are compressed together. The pressure increases and exceeds the elastic potential energy of the first one-way valve. The moisture is sprayed from the first one-way valve to the inner wall of the lower hopper, and then the concave ring moves upward and resets, completing a pump air water spraying project.
[0013] Furthermore, the reciprocating mechanism also includes an assembly seat, the right-angle rod is fixedly connected to the concave ring member and the assembly seat, a threaded hole is provided on the assembly seat, the threaded hole is connected to the threaded rod by a thread, and the concave ring member is also provided with a liquid outlet and an air outlet, the liquid outlet is arranged on the outer wall of the concave ring member, and the air outlet is arranged on the inner wall of the concave ring member, and several groups of liquid outlet holes and air outlet holes are evenly distributed along the circumference of the concave ring member.
[0014] The impeller rotates at high speed to transmit torque to the threaded rod. Through the threaded connection between the threaded rod and the threaded hole, the right-angle rod moves back and forth up and down in the sliding hole. The concave ring assembled with the right-angle rod moves back and forth up and down in the shell. The moisture in the gas is collected by the filtrate ring and leaks into the concave ring through the leakage groove and the liquid collecting slope. The ejector pin contacts and pushes open the second one-way valve to allow external air to enter the concave ring. The concave ring moves downward, and the leakage groove is blocked by the shell. The collected moisture liquid enters the shell through the liquid outlet hole and the liquid return groove first. The concave ring continues to move downward, and the liquid outlet hole is blocked by the shell. The gas in the concave ring enters the shell through the air outlet hole and the air return groove. The moisture and gas in the space below the shell are compressed together, and the pressure increase exceeds the elastic potential energy of the first one-way valve, and the moisture is sprayed from the first one-way valve to the inner wall of the lower hopper.
[0015] Furthermore, the pulse mechanism also includes a high-pressure gas tank and an electromagnetic pulse valve. The high-pressure gas tank is fixedly connected to the side frame. The electromagnetic pulse valve is provided in several groups. The several groups of electromagnetic pulse valves are linearly evenly distributed along the axis of the high-pressure gas tank. The electromagnetic pulse valve is connected to the high-pressure gas tank and the gas distribution pipe through pipelines.
[0016] As the filtering process continues, the dust layer on the surface of the fiber filter bag continues to thicken, causing the resistance of the dust collector to gradually increase. The electromagnetic pulse valve opens intermittently, and the compressed air in the high-pressure gas tank passes through the gas distribution pipe and instantly sprays into the fiber filter bag at high speed, causing it to expand rapidly.
[0017] Furthermore, the filtering mechanism also includes an air collecting hopper and a fiber filter bag. An exhaust port is provided on the partition.

[0018] The vacuum pump is started to draw the dust-containing gas into the box through the air inlet pipe. When the dust passes through the fiber filter bag, it is adsorbed on the outer surface of the fiber filter bag due to inertial collision, interception, diffusion, etc. The clean gas passes through the fiber filter bag and is pumped out of the air outlet by the vacuum pump. The compressed air passes through the air distribution pipe and is instantly sprayed into the fiber filter bag at high speed, causing it to expand rapidly. The generated shock wave causes the dust layer on the surface of the fiber filter bag to fall off and fall into the lower hopper.
[0019] Furthermore, the unloading mechanism also includes a base frame, a unloading motor and a unloading barrel. The base frame and the unloading motor are fixedly connected to the unloading hopper, and the output end of the unloading motor is fixedly connected to the unloading barrel.
[0020] The generated shock wave causes the dust layer on the surface of the fiber filter bag to fall off and fall into the lower hopper. The first one-way valve sprays the recovered water on the inner wall of the lower hopper to cause the falling dust to agglomerate. The agglomerated dust falls along the lower hopper into the lower barrel. The lowering motor outputs a fixed-axis torque to the lower barrel to cause the agglomerated dust to rotate out.

The dry dust-containing gas surrounds the filtrate ring and passes upward through the air outlet for filtration, thereby removing the moisture in the air and preventing the moisture-containing dust from condensing and adhering to the fiber filter bag; the present invention designs a ring shell and a reciprocating mechanism; the impeller rotates at a high speed to transmit the torque to the threaded rod, and through the threaded connection between the threaded rod and the threaded hole, the right-angle rod is equipped with a concave ring member that moves back and forth up and down in the shell, and the moisture in the gas is collected by the filtrate ring The collected water leaks into the concave ring through the leakage groove and the liquid collecting slope, and the ejector pin contacts and pushes open the second one-way valve, allowing external air to enter the concave ring.

The concave ring continues to move downward, and the gas in the concave ring enters the shell through the air outlet and the air return groove. The water and gas in the space below the shell are compressed together, and the water is sprayed from the first one-way valve to the inner wall of the lower hopper. The recovered water is used to clean the inner wall of the lower hopper, so that the fallen dust is discharged, and the internal self-cleaning improves the filtering effect. On the basis of pulse dust removal, the present invention adapts to the air environment with high humidity, avoids the condensation of dust and gas with high humidity adhering to the filter bag, which affects the dust removal efficiency, and at the same time performs water-impact self-cleaning on the box body to improve the filtering effect.

The first side hole 12 and the air distribution pipe 53 are each provided with a plurality of groups, and the plurality of groups of first side holes 12 are uniformly distributed along the horizontal linear distribution of the box body 1.

[0026] The present invention is a dry-type filtering dust removal equipment used in industrial production. The vacuum pump 2 is started to draw dust-containing gas from the air inlet pipe 3 into the box 1. The dust-containing gas first passes through the dehumidification mechanism 4 to discharge the moisture in the gas and then passes into the filtering mechanism 6 to prevent the moisture-containing dust from condensing and adhering to the fiber filter bag 63. When the dust passes through the fiber filter bag 63, it is adsorbed on the outer surface of the fiber filter bag 63 due to inertial collision, interception, diffusion, etc. The clean gas passes through the fiber filter bag 63 and the air outlet 11 and is exhausted. Pump 2 draws out, and as the filtering process continues, the dust layer on the surface of the fiber filter bag 63 continues to thicken, causing the resistance of the dust collector to gradually increase. The pulse mechanism 5 sprays compressed air through the air distribution pipe 53 into the fiber filter bag 63 at high speed in an instant, causing it to expand rapidly. The generated shock wave causes the dust layer on the surface of the fiber filter bag 63 to fall off and fall into the lower hopper 72. The dehumidification mechanism 4 sprays the recovered moisture on the inner wall of the lower hopper 72 to cause the falling dust to agglomerate, thereby improving the filtering effect by internal self-cleaning.

[0028] The vacuum pump 2 is started to draw the dust-containing gas into the box body 1 through the air inlet pipe 3. The dust-containing gas is drawn to the bottom of the chassis 421. Under the action of the centrifugal mechanism 42, the gas is thrown to the filtrate ring 45, and the dry dust-containing gas passes upward. The moisture in the gas is collected by the filtrate ring 45 and leaks into the reciprocating mechanism 44 through the leakage groove 4421 and the liquid collecting slope 4313. The reciprocating mechanism 44 continues to pump air into the annular shell 43 through the second one-way valve 433, and finally the collected moisture is sprayed onto the inner wall of the lower hopper 72.

The driving motor 422 and the upper arc cover 424 are both fixedly connected to the chassis 421. The output end of the driving motor 422 is fixedly connected to the impeller 423. The upper arc cover 424 and the outer arc shell 425 form an air outlet 426. The reciprocating mechanism 44 also includes a threaded rod 444, which is fixedly connected to the impeller 423.

The moisture in the gas is collected by the filtrate ring 45 and leaks into the ring shell 43 through the leakage groove 4421 and the liquid collecting slope 4313. The dry dust-containing gas goes around the filtrate ring 45 and passes upward through the outlet duct 426 between the upper arc cover 424 and the outer arc shell 425.

The ejector pin 4424 contacts and pushes open the second one-way valve 433, allowing external air to enter the concave ring 442. The reciprocating mechanism 44 drives the concave ring 442 to move downward, and the collected moisture liquid first enters the shell 431 through the return liquid groove 4311, and then the gas in the concave ring 442 enters the shell 431 through the return gas groove 4312. When the concave ring 442 moves downward, it squeezes the space below the shell 431, and the moisture and gas in the space below the shell 431 are compressed together. The pressure increases and exceeds the elastic potential energy of the first one-way valve 432. The moisture is sprayed from the first one-way valve 432 to the inner wall of the lower hopper 72, and then the concave ring 442 moves upward and resets, completing a pump air water spraying project.

[0034] The impeller 423 rotates at a high speed to transmit torque to the threaded rod 444. Through the threaded connection between the threaded rod 444 and the threaded hole 4431, the right-angle rod 441 moves back and forth up and down in the sliding hole 4316. The right-angle rod 441 is equipped with a concave ring 442 and moves back and forth up and down in the housing 431. The moisture in the gas is collected by the filtrate ring 45 and leaks into the concave ring 442 through the leakage groove 4421 and the liquid collecting slope 4313.

The electromagnetic pulse valve 52 is connected to the high-pressure gas tank 51 and the gas distribution pipe 53 through pipelines.
[0036] As the filtering process continues, the dust layer on the surface of the fiber filter bag 63 continues to thicken, causing the resistance of the dust collector to gradually increase. The electromagnetic pulse valve 52 opens intermittently, and the compressed air in the high-pressure gas tank 51 passes through the gas distribution pipe 53 and is instantly sprayed into the fiber filter bag 63 at high speed, causing it to expand rapidly.

[0040] The generated shock wave causes the dust layer on the surface of the fiber filter bag 63 to fall off and fall into the lower hopper 72. The first one-way valve 432 sprays the recovered water on the inner wall of the lower hopper 72 to cause the falling dust to agglomerate. The agglomerated dust falls along the lower hopper 72 into the lower barrel 74. The lowering motor 73 outputs a fixed-axis torque to the lower barrel 74 to rotate the agglomerated dust out.
[0041] The working principle of the present invention is as follows: the vacuum pump 2 is started to draw dusty gas from the air inlet pipe 3 into the box body 1, the dusty gas is drawn to the bottom of the chassis 421, the driving motor 422 drives the impeller 423 to rotate at high speed to transmit torque to the threaded rod 444, the impeller 423 throws the gas to the inner wall of the filtrate ring 45, through the threaded connection between the threaded rod 444 and the threaded hole 4431, the right-angle rod 441 is equipped with a concave ring 442 to move back and forth up and down in the shell 431, and when the concave ring 442 is located at the upper end of the shell 431, the moisture in the gas is filtered out. Liquid ring 45 collects liquid through leakage groove 4421 and liquid collecting slope 4313 and leaks into concave ring 442. Ejector pin 4424 contacts and pushes open second one-way valve 433, allowing external air to enter concave ring 442. Concave ring 442 moves downward, leakage groove 4421 is blocked by shell 431, and the collected water first enters shell 431 through liquid outlet hole 4422 and liquid return groove 4311. Concave ring 442 continues to move downward, liquid outlet hole 4422 is blocked by shell 431, and gas in concave ring 442 passes through gas outlet hole 442. 3. The return air groove 4312 enters the shell 431, and the water and gas in the lower space of the shell 431 are compressed together. The pressure increases and exceeds the elastic potential energy of the first one-way valve 432. The water is sprayed from the first one-way valve 432 to the inner wall of the lower hopper 72. The dry dust-containing gas flows around the filter liquid ring 45 and passes upward through the outlet 426 between the upper arc cover 424 and the outer arc shell 425 to prevent the water-containing dust from condensing and adhering to the fiber filter bag 63. The dust is adsorbed on the outer surface of the fiber filter bag 63, and the clean gas passes through the outlet 11 The dust layer on the surface of the fiber filter bag 63 is sucked out by the vacuum pump 2. With continuous filtering, the dust layer on the surface of the fiber filter bag 63 continues to thicken, the dust removal resistance increases, the electromagnetic pulse valve 52 opens intermittently, and the compressed air in the high-pressure gas tank 51 passes through the air distribution pipe 53 and is instantly sprayed into the fiber filter bag 63 at high speed, causing it to expand rapidly. The shock wave generated causes the dust layer on the surface of the fiber filter bag 63 to fall off and fall into the lower hopper 72. The dehumidification mechanism 4 sprays the recovered moisture on the inner wall of the lower hopper 72, causing the fallen dust to agglomerate and fall for recovery, thereby improving the filtering effect for internal self-cleaning.
