Description

Technical Field

[0001] The present invention relates to the technical field of waste gas filtration, and specifically to an exhaust gas cleaning device based on a chemical hazardous waste incineration kiln. Background Technique

[0002] During the industrial production process, especially during the operation of equipment such as rotary kiln incinerators, a large amount of tail gas is generated, which contains harmful substances such as large particulate impurities, dust, acidic or alkaline gases, and heavy metals. If these tail gases are directly discharged into the atmosphere, it will cause serious environmental pollution and pose a threat to human health. Traditional tail gas treatment uses filter plates for filtration. However, during the use of filter plates, the filtration effect gradually decreases. When the filtered waste gas volume is lower than the waste gas inlet volume, the filter plates need to be replaced, resulting in an increase in maintenance costs.

[0022] The filter plate 15 is installed on the blocking plate 14, and the position of the slider 26 in the chute is changed by using the air pressure between the filter plate 15 and the partition plate 16, so that the blocked area of the filter plate 15 is changed, and the filterable area of the filter plate 15 can be increased as the filtration efficiency decreases.

[0023] An installation cylinder 28 is installed in the exhaust passage 4. A push rod 34 is inserted into the installation cylinder 28. One end of the push rod 34 away from the installation cylinder 28 is hinged to the filter plate 15. A moving plate 31 is slidably connected in the installation cylinder 28. A second elastic member 29 is installed at one end of the moving plate 31 away from the push rod 34. The second elastic member 29 is a spring and is in a normal state. One end of the second elastic member 29 away from the moving plate 31 is installed in the installation cylinder 28. An L-shaped rod 35 is installed on the side of the moving plate 31 facing the push rod 34. One end of the L-shaped rod 35 away from the moving plate 31 is hinged to an inclined block 30. A plurality of inclined grooves 33 are formed on the side of the push rod 34 facing the L-shaped rod 35. The inclined block 30 is inserted into the inclined grooves 33. A third elastic member 32 is installed on the side of the inclined block 30 away from the moving plate 31. The third elastic member 32 is a spring and is in a normal state. One end of the third elastic member 32 away from the inclined block 30 is connected to the L-shaped rod 35.

[0024] The pulling structure composed of the installation cylinder 28, the push rod 34, the moving plate 31, the second elastic member 29, the L-shaped rod 35, the inclined block 30 and the third elastic member 32 is utilized, and the movement of the filter plate 15 is restricted by the pulling structure, so as to ensure that the filter plate 15 always meets the filtering requirements of the waste gas in the exhaust tower 1.

[0025] A rotating ring 23 is installed on one side of the exhaust passage 4 close to the exhaust tower 1. A rotating rod 11 is installed in the rotating ring 23. A plurality of rotating plates 10 are installed on the circumferential surface of the rotating rod 11. A first hinge rod 24 is installed on the circumferential surface of the rotating rod 11. One end of the first hinge rod 24 away from the rotating rod 11 is hinged to a second hinge rod 25. One end of the second hinge rod 25 away from the first hinge rod 24 is hinged to a reciprocating rod 7.

[0026] A through groove is formed on the outer surface of the exhaust passage 4. Two support rods 27 are installed on the side of the slider 26 away from the filter plate 15. The two support rods 27 pass through the through groove and extend to the outside of the exhaust passage 4, and a swing cylinder 6 is installed at one end outside the exhaust passage 4. A swing rod 5 is rotatably connected in the swing cylinder 6. The swing rod 5 is in contact with the reciprocating rod 7. A knocking rod 13 is installed on the circumferential surface of the swing rod 5. One end of the knocking rod 13 away from the swing rod 5 is inserted into the exhaust passage 4 and a knocking block 12 is installed, and the knocking block 12 is in contact with the filter plate 15.

[0027] By installing exhaust channels 4 on both sides of the exhaust tower 1 respectively, and indirectly contacting the reciprocating structure composed of a rotating ring 23, a rotating cylinder, a rotating plate 10, a first hinged rod 24, a second hinged rod 25 and a reciprocating rod 7 with the knocking structure composed of a support rod 27, a swinging cylinder 6, a swinging rod 5, a knocking rod 13 and a knocking block 12, when the exhaust channel 4 on one side exhausts, it drives the knocking structure in the exhaust channel 4 on the other side to contact the filter plate 15, and knocks and cleans the dust on the filter plate 15, thereby increasing the service life of the filter plate 15. And because the support rod 27 is connected to the slider 26, when the position of the slider 26 changes, it can also drive the position of the knocking structure to change, so that the knocking block 12 always knocks on the most severely blocked area of the filter plate 15.

[0028] Arc-shaped blocks 19 are installed on both sides inside the exhaust tower 1. Both ends of the swinging plate 17 are in sliding contact with the two arc-shaped blocks 19. A waste discharge hole 8 is opened on the side of the arc-shaped block 19 facing the outside of the exhaust tower 1. A collection box 2 is installed outside the waste discharge hole 8. An arc-shaped groove 18 is opened in the waste discharge hole 8. A sealing plate 9 is inserted into the arc-shaped groove 18. One end of the sealing plate 9 facing the waste discharge hole 8 is in contact with the swinging plate 17. A first elastic member 20 is installed at one end of the sealing plate 9. The first elastic member 20 is a spring, and the first elastic member is in a normal state. The end of the first elastic member 20 away from the sealing plate 9 is installed in the arc-shaped groove 18.

[0029] When the swinging plate 17 opens one side of the exhaust passage, the other side of the swinging plate 17 can contact the arc-shaped block 19 and open the waste discharge hole 8 communicating with the exhaust passage 4 on the other side to collect the knocked-off dust. And the inclined swinging plate 17 can serve as a platform for the dust to contact the waste discharge hole 8, so that the dust can enter the waste discharge hole 8 more accurately.

[0030] In summary, for this waste gas cleaning device based on a chemical waste incinerator, during use, first start the drive motor 3 to drive the swinging plate 17 to rotate, so that the swinging plate 17 tilts to one side and opens the exhaust passage 4 on this side. Subsequently, the waste gas in the exhaust tower 1 enters the exhaust passage 4 and contacts the filter plate 15, and the filter plate 15 is used to filter the waste gas. When the filtering efficiency of the filter plate 15 decreases due to long-term use, the gas discharged from the exhaust tower 1 causes the waste gas to accumulate between the filter plate 15 and the partition plate 16 and increases the air pressure in this area. Then, it pushes the filter plate 15 and the blocking plate 14 to deflect, so that the area of the filter plate 15 blocked by the blocking plate 14 after deflection decreases, and then a larger area of the filter plate 15 filters the waste gas, ensuring that the filter plate 15 always meets the filtering requirements of the waste gas in the exhaust tower 1.

[0031] When the exhaust gas enters the exhaust passage 4, it drives the rotary plate 10 to rotate. The rotation of the rotary plate 10 drives the rotating rod 11 to rotate. The rotation of the rotating rod 11 drives the reciprocating rod 7 to reciprocate by means of the first hinge rod 24 and the second hinge rod 25. When the reciprocating rod 7 reciprocates, it contacts the swing rod 5 and drives the knocking block 12 to separate from the filter plate 15. When the reciprocating rod 7 separates from the swing rod 5, the knocking block 12 returns to its original position under its own gravity and contacts the filter plate 15, separating the dust clogged on the filter plate 15, increasing the service life of the filter plate 15. Moreover, when the swing plate 17 opens one side of the exhaust passage, the other side of the swing plate 17 can contact the arc-shaped block 19 and open the impurity discharge hole 8 communicating with the exhaust passage 4 on the other side to collect the knocked-off dust.

[0032] After the filter plate 15 and the blocking plate 14 deflect, the position of the slider 26 in the chute changes. The change in the position of the slider 26 drives the change in the position of the support rod 27. The change in the position of the support rod 27 further drives the change in the position of the knocking rod 13 and the knocking block 12, so that the knocking block 12 always knocks on the most severely clogged area of the filter plate 15.

[0033] The embodiments of the present invention are given for the purposes of illustration and description, and are not exhaustive or limit the invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art.
