[0002] Thermal storage combustion treatment of industrial waste gas has the characteristics of high purification efficiency, simple operation and low cost. However, industrial waste gas often contains sticky substances in a tar-like state. These tar-like sticky substances form deposits in the low-temperature area of ​​the thermal storage material of the thermal storage oxidation reactor, the common channel, the inlet and outlet air ducts, the sealing surface of the lifting valve and other places where the waste gas passes, and adhere to all surfaces where the waste gas passes; the thermal storage material of the thermal storage oxidation reactor is very easy to be blocked by tar-like sticky substances due to the narrow waste gas channel and the large specific surface area, which causes severe operation interruption. Moreover, once these deposited substances are ignited by high temperature, they will cause fire accidents. Therefore, it is necessary to conduct preliminary purification of industrial waste gas before thermal storage combustion treatment.

[0033] Working principle and advantages of the present invention: When the heat storage combustion purification device for industrial waste gas is used, the working process is as follows:

[0034] like Figure 1 and Figure 2As shown, starting the motor 32 causes the motor 32 to drive the main shaft 31 and the tooth column 30 thereon to rotate synchronously with the turntable 29, thereby causing the turntable 29 to drive the first protrusion 45 and the second protrusion 46 on both sides thereof to rotate synchronously. After the turntable 29 drives the second protrusion 46 to pass through the dial ear 33, the dial ear 33 is toggled to the left under the action of the second protrusion 46, so that the dial ear 33 drives the valve stem 4 to slide to the left in the valve cylinder 3 through the dial rod 34, thereby causing the valve hole 1 48 to be staggered and not connected with the through hole 1 49, and the valve hole 2 51 to be connected with the through hole 2 50. After the turntable 29 drives the first protrusion 45 to pass through the dial ear 33, the dial ear 33 is toggled to the right under the action of the first protrusion 45, so that the dial ear 33 drives the valve stem 4 to slide to the right in the valve cylinder 3 through the dial rod 34, thereby causing the valve hole 2 51 to be staggered and not connected with the through hole 2 50, and the valve hole 1 48 to be connected with the through hole 1 49.

[0035] As mentioned above, the industrial waste gas is delivered to the left end of the valve cylinder 3, such as Figure 5 As shown, when the valve hole 2 51 is connected with the through hole 2 50, the industrial waste gas enters the second filter box 24 through the channel 47, the valve hole 2 51, the through hole 2 50 and the pipeline 2 6. After the sticky substances are filtered out by the filter screen 22 in the second filter box 24, the purified industrial waste gas is output through the exhaust pipe 20 for heat storage combustion treatment. When the valve hole 1 48 is connected with the through hole 1 49, the industrial waste gas enters the first filter box 7 through the channel 47, the valve hole 1 48, the through hole 1 49 and the pipeline 1 5. After the sticky substances are filtered out by the filter screen 22 in the first filter box 7, the purified industrial waste gas is output through the exhaust pipe 8 for heat storage combustion treatment, and the two filter screens 22 are used to filter and purify the industrial waste gas, remove the sticky substances, thereby avoiding the deposition of sticky substances, maintaining the stable and efficient heat storage combustion treatment, reducing safety risks, and alternately replacing the industrial waste gas transmission path, so that the industrial waste gas alternately passes through the two filter screens 22, thereby maintaining the efficient filtering effect of the filter screen 22.

[0036] As described above, when the valve hole 2 51 is connected to the through hole 2 50, the valve hole 1 48 is staggered and not connected to the through hole 1 49. At this time, the industrial waste gas enters the second filter box 24, so that the pressure in the second filter box 24 increases, and the pressure in the first filter box 7 decreases. Under the action of the pressure difference, the slide plate 16 in the slide cylinder 2 17 moves to the left, and the corresponding connecting rod 15 pushes the sleeve 27 to move left, so that the sleeve 27 drives the shaft rod 11 to move left through the shaft frame 1 13, and the shaft rod 11 drives the gear 2 10 to mesh with the gear 1 9. At this time, the gear 3 18 is disengaged from the gear 4 19 and the rotation of the tooth column 30 drives the gear 5 44 to rotate, so that The gear five 44 drives the shaft three 42 to rotate through the bevel gear set three 28, and the shaft three 42 drives the shaft one 11 to rotate through the bevel gear set one 12, and then the shaft one 11 drives the gear one 9 to rotate through the gear two 10, and the gear one 9 drives the filter plate 22 to rotate through the shaft two 36, and at the same time drives the corresponding spiral blade shaft 38 to rotate through the core disk 37 and the bevel gear set two 23, so that the edge of the spiral blade shaft 38 scrapes the sticky material adhered to the bottom surface of the filter plate 22 and falls into the drain pipe 21 and is discharged into the conduit 39, and then gathers in the storage box 40. When the storage box 40 is full, it is unscrewed and replaced with an empty storage box 40.

[0037] When the valve hole 1 48 is connected to the through hole 1 49, the valve hole 2 51 is staggered and not connected to the through hole 2 50. At this time, the industrial waste gas enters the first filter box 7, so that the pressure in the first filter box 7 increases, and the pressure in the second filter box 24 decreases. Under the action of the pressure difference, the slide plate 16 in the slide cylinder 14 moves to the right, and the corresponding connecting rod 15 pushes the shaft sleeve 27 to move to the right, so that the shaft sleeve 27 drives the shaft rod 1 11 to move to the right through the shaft frame 1 13, and the shaft rod 1 11 drives the gear 3 18 to mesh with the gear 4 19. At this time, the gear 2 10 is disengaged from the gear 1 9, and the shaft rod 1 11 rotates through the gear 3 18 and the gear 4 19. , so that the gear four 19 drives the filter screen plate 22 to rotate through the corresponding shaft rod two 36, and at the same time drives the corresponding spiral blade shaft 38 to rotate through the core plate 37 and the bevel gear set two 23, so that the edge of the spiral blade shaft 38 scrapes the sticky material adhered to the bottom surface of the filter screen plate 22 in the second filter box 24 and falls into the drain pipe 21 and is discharged into the conduit 39, and then gathers in the storage box 40. In this way, one filter screen plate 22 filters and purifies the industrial waste gas while the other filter screen plate 22 is cleaned and decontaminated, thereby maintaining a high-efficiency filtering and purification effect on the industrial waste gas, and the filter screen plate 22 has an automatic cleaning function, saving time and effort.
