Technical Field

[0001] The invention relates to the technical field of chemical waste gas treatment, and in particular to a chemical reactor waste gas treatment device and a use method thereof. Background Art

[0002] The reactor is a comprehensive reaction vessel. The design of the reactor structure, function and accessories is based on the reaction conditions. From the initial feeding-reaction-discharging, the pre-set reaction steps can be completed with a high degree of automation. The structure design and parameter configuration of the container are carried out according to different process conditions. The design conditions, process, inspection, manufacturing and acceptance must be based on relevant technical standards to achieve the heating, evaporation, cooling and low-speed mixing reaction functions required by the process. The design requirements for the container are different with the pressure requirements in the reaction process. The production must be strictly processed, tested and tested in accordance with the corresponding standards. The exhaust gas generated during the operation of the reactor must be treated before it can flow into the air to reduce air pollution and make it more environmentally friendly.

[0003] The principle of the existing reactor waste gas treatment device is to first perform dry purification filtration and then wet filtration purification. The dry filtration method is to pass the waste gas through a filter plate containing filter material (activated carbon), and the wet filtration method is to spray the gas after dry filtration with a harmful substance adsorption liquid.

The filter plate is rotatably connected to the fan groove via the rotating shaft, and the rotating shaft passes through the filter plate and extends into the circular groove.

[0012] The outer ring of the ring sleeve is provided with an annular groove, and a transmission ring is rotatably connected in the annular groove, and a one-way bearing is arranged between the transmission ring and the annular groove.

[0013] One end of the rotating shaft close to the transmission ring is provided with ring teeth, and the surface of the transmission ring is provided with four arc teeth corresponding to the ring teeth respectively.

[0014] The outer surface of the filter cartridge is symmetrically provided with two flushing air pipes matched with the filter disc, and the flushing air pipes are located on the side of the filter disc opposite to the air inlet pipe.

[0015] The filter disc, the transmission ring and the filter cartridge are provided with automatic cleaning components.

[0016] Preferably, the automatic cleaning component includes embedded grooves opened along the inner side walls on both sides of the fan groove, and the embedded grooves are connected to the circular grooves. A brush rod corresponding to the embedded grooves is fixedly provided on the surface of the ring sleeve, and the brush rod is located in the embedded grooves.

[0017] The inside of the filter disc is provided with a collecting groove which is communicated with the embedding groove, and the collecting groove penetrates the outer ring of the filter disc, and the outer surface of the filter cartridge is provided with a suction nozzle which matches with the collecting groove.

[0018] Preferably, the filter cartridge is composed of two half-cylinders, and the two half-cylinders are connected by bolts.

[0020] Preferably, a slot cooperating with the bracket is provided on the inner side wall of the semi-cylinder.

[0021] Preferably, the filter plate is fixedly connected to the rotating shaft by screws.

[0022] A method for using a chemical reactor waste gas treatment device comprises the following steps:

[0023] S1. The waste gas in the reactor is fed into the filter cartridge along the air inlet pipe, and after the particles are filtered by the filter sheet on the filter disc, the waste gas is fed into the next treatment process along the air outlet pipe;

[0024] S2, control the exhaust gas to intermittently pass through the filter plate for filtration, the airflow pushes the filter plate to stretch the elastic rope and move it toward the inflation pipe. When the air is stopped, the elastic rope is used to pull the filter plate back and squeeze the exhaust gas filter on the intake pipe side toward the inflation pipe side. In this process, the force-bearing magnetic block is pulled by the magnetic force of the traction magnetic block, driving the filter plate to rotate along the magnetic track and causing the filter plates at different positions to exchange positions;

[0025] S3. During the process of the filter disc moving backward and rotating, the ring sleeve inside it is kept in the same position by the counterweight, that is, the ring sleeve rotates relatively along the filter disc, and the one-way bearing makes the transmission ring follow the ring sleeve to use the arc teeth along the ring teeth to push the shaft and the filter disc to rotate 180°. At this time, the flushing air pipes on both sides use the airflow to flush the particles on the flipped filter disc and take them out. When the filter disc moves forward and rotates, the one-way bearing disconnects the transmission ring from the ring sleeve.

[0026] S4. After the filter disc is flipped, the continuously rotating ring sleeve drives the brush rod to swing from the embedded groove to the fan groove, and sweeps the particles accumulated on the surface of the filter disc into the embedded groove until they are pushed into the collection groove. When the filter disc moves back to its position, the outer notch of the collection groove is aligned with the suction nozzle to extract the particles in the collection groove from the outside of the filter cartridge along the suction nozzle.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] In the present invention, the filter disc is pushed by airflow to stretch the elastic rope and move it toward the inflation tube. When the air is stopped, the elastic rope is used to pull back the filter disc and squeeze the exhaust gas filter on the intake pipe side toward the inflation tube. During this process, the force-bearing magnetic block is pulled by the magnetic force of the traction magnetic block, driving the filter disc to rotate along the magnetic track and causing the filter sheets at different positions to exchange positions. Compared with the existing spring slide structure, the filter disc is connected by an elastic rope, and then the traction magnetic block and the force-bearing magnetic block are used to cooperate for non-contact deflection control. On the one hand, it can prevent the physical connection structure from being stuck and disturbed by particulate matter in the exhaust gas, thereby affecting normal use. On the other hand, it can continuously exchange the positions of each filter sheet to prevent particulate matter in the exhaust gas from being filtered and accumulated on the lower filter sheet due to its own weight, thereby effectively ensuring the utilization rate of all filter sheets.

[0029] In the present invention, the ring sleeve inside the filter disc is kept in position by a counterweight, that is, the ring sleeve rotates relatively along the filter disc, and the one-way bearing enables the transmission ring to follow the movement of the ring sleeve, so that the arc teeth are used along the ring teeth to push the rotating shaft and the filter plate to rotate 180°. At this time, the flushing air pipes on both sides use the airflow to flush and take out the particulate matter on the flipped filter plate. Compared with the existing fixed filter element, the above-mentioned ring sleeve can be relatively rotated by the counterweight, and the two sides of the filter plate are switched in opposite directions, and then flushed and cleaned by airflow. On the one hand, the back side of the filter plate can be fully utilized, avoiding the rapid loss of the filter plate due to single-sided use, and extending the service life of the filter element. On the other hand, the filter element can be quickly cleaned without shutting down the equipment for disassembly, reducing interference with the processing operation.

[0030] In the present invention, the rotating ring sleeve drives the brush rod to swing from the embedded groove to the fan groove, and sweeps the particles accumulated on the surface of the filter into the embedded groove until they are pushed into the collecting groove. When the filter disc is moved back into position, the outer notch of the collecting groove is aligned with the suction nozzle, so that the particles in the collecting groove can be extracted from the outside of the filter cartridge along the suction nozzle. Compared with large-scale air flow flushing, the brush rod can scrape and clean the flipped filter more accurately, and can temporarily store the cleared particles in the filter disc and automatically extract them later. There is no need for the operator to wait for the filter disc to be reversed and then start the flushing operation separately. BRIEF DESCRIPTION OF THE DRAWINGS

The airflow pushes the filter disc 4 to stretch the elastic rope 62 and displace it toward the inflation pipe. When the air is stopped, the elastic rope 62 is used to pull back the filter disc 4 and squeeze the exhaust gas on the side of the intake pipe 2 to the side of the inflation pipe. Two force-bearing magnetic blocks 63 are fixedly embedded in the outer ring of the filter disc 4, and the two force-bearing magnetic blocks 63 are horizontally symmetrically distributed along the filter disc 4. A plurality of traction magnetic blocks 64 are fixedly embedded on the inner wall of the filter cartridge 1, and the plurality of traction magnetic blocks 64 are equally divided into two groups to form a magnetic track that cooperates with the force-bearing magnetic blocks 63 on the same side.

[0045] The magnetic track formed by a single set of traction magnetic blocks 64 is set as a spiral structure. During the displacement of the filter disc 4 in the direction of the inflation tube, the force-bearing magnetic block 63 is pulled by the magnetic force of the traction magnetic block 64, driving the filter disc 4 to rotate along the magnetic track and causing the filter sheets 5 at different positions to exchange positions.

[0059] A method for using a chemical reactor waste gas treatment device comprises the following steps:

At this time, the flushing air pipes 6511 on both sides use the airflow to flush the particles on the flipped filter plate 5 and bring them out. When the filter disc 4 moves forward and rotates, the one-way bearing 658 disconnects the transmission ring 657 from the ring sleeve 652.

[0063] S4. After the filter plate 5 is flipped, the continuously rotating ring sleeve 652 drives the brush rod 65122 to swing from the embedded groove 65121 to the fan groove 654, and sweeps the particles accumulated on the surface of the filter plate 5 into the embedded groove 65121 until they are pushed into the collection groove 65123.

S3, during the process of the filter disc (4) moving backward and rotating, the ring sleeve (652) inside the filter disc (4) is kept in a constant position by means of the counterweight block (653), that is, the ring sleeve (652) rotates relatively along the filter disc (4), and the one-way bearing (658) causes the transmission ring (657) to move along the ring sleeve (652), so that the arc teeth (6510) are used to push the rotating shaft (655) and the filter disc (5) to rotate 180 degrees along the ring teeth (659), and at this time, the flushing air pipes (6511) on both sides use the airflow to flush the particles on the flipped filter disc (5) and bring them out, and when the filter disc (4) moves forward and rotates, the one-way bearing (658) disconnects the transmission ring (657) from the ring sleeve (652); S4. After the filter plate (5) is turned over, the continuously rotating ring sleeve (652) drives the brush rod (65122) to swing from the embedded groove (65121) to the fan groove (654), and sweeps the particles accumulated on the surface of the filter plate (5) into the embedded groove (65121) until they are pushed into the collection groove (65123). When the filter disc (4) moves back to its original position, the outer notch of the collection groove (65123) is aligned with the suction nozzle (65124), so that the particles in the collection groove (65123) are extracted from the outside of the filter cartridge (1) along the suction nozzle (65124).
