Then, the exhaust gas intake pipe diverts low-concentration and high-flow exhaust gas into the elastic treatment tube. After being adsorbed by the activated carbon, it is discharged through the treatment exhaust pipe. During the activated carbon adsorption, the elastic activation component works intermittently, and the upper vibration plate and the lower vibration plate are elastically supported by the spring body. Then, the vibration motor is activated to drive the upper vibration plate and the lower vibration plate to move closer and farther from each other, thereby driving the elastic treatment tube to perform elastic movement, causing displacement between the activated carbon inside the elastic treatment tube, which can make the unsaturated surface of the activated carbon Enter the exhaust gas through the gap; improve the exhaust gas treatment effect; when a certain elastic treatment tube works for the first threshold time, close the elastic treatment tube, the first thermal activation component is activated, the hot air furnace generates high-temperature hot air, and the high-temperature hot air is injected from the top of the elastic treatment tube, and the activated carbon is impacted and desorbed, and the enriched exhaust gas is injected into the enriched exhaust gas treatment unit with high-pressure hot air to complete the primary thermal desorption of the activated carbon; and re-invest in the exhaust gas treatment, when a certain elastic treatment tube works for the second threshold time, close the elastic treatment tube, the second thermal activation component is activated, the upper electric rotary valve and the lower electric rotary valve are activated. The valves act synchronously, so that new activated carbon is filled into the elastic treatment tube while the saturated activated carbon is rotated out of the elastic treatment tube to achieve activated carbon replacement inside the elastic treatment tube; the upper electric rotary valve and the lower electric rotary valve can ensure that the elastic treatment tube is in a closed state in real time; the hot gas from the primary thermal desorption blows the enriched exhaust gas from the top to the bottom of the elastic treatment tube and leaves the elastic treatment tube, and the activated carbon from the secondary thermal desorption is filled from the top to the bottom of the elastic treatment tube.

Carbon or fully activated activated carbon can ensure the treatment effect and avoid the re-pollution of the discharged treated waste gas; the saturated activated carbon discharged by the lower electric rotary valve is sent to the distribution tunnel, and then the metal mesh conveyor belt reciprocates to spread the saturated activated carbon to the top surface of the metal mesh conveyor belt through the spreading plate, and the heater is turned on to fully desorb the activated carbon with high temperature heat, and the desorbed enriched waste gas is sent to the enriched waste gas treatment unit, and the enriched waste gas is treated by the enriched waste gas treatment unit; finally, the hydraulic lifting door is opened to send the desorbed activated carbon to the low-level hopper through the metal mesh conveyor belt.

[0011] Furthermore, the elastic management tube includes an upper management chamber and a lower management chamber which are movably engaged with each other, and a plurality of sealing rings are arranged between the upper management chamber and the lower management chamber; the upper part of the upper management chamber and the lower part of the lower management chamber are provided with mounting ears fixed to the upper vibration plate and the lower vibration plate; the upper management chamber and the lower management chamber are externally sleeved with a spring tube, the upper part of the spring tube is fixed to the outside of the upper management chamber, and the lower part of the spring tube is fixed to the outside of the lower management chamber; connecting flanges are arranged on the top of the upper management chamber and the bottom of the lower management chamber, and when working, the elastic activation component drives the upper vibration plate and the lower vibration plate to approach and move away from each other, thereby driving the upper management chamber and the lower management chamber to approach and move away from each other, and when in action, they are always sealed by the sealing ring, so as to realize vibration activation of the activated carbon on the top of the upper management chamber and inside the lower management chamber.

[0012] Furthermore, the heater is a combustion heater or a heat exchange heater, and the heat exchange heater includes an S-shaped heat exchange tube, both ends of which are connected to a steam heater or a thermal oil heater; when the heater treats the saturated activated carbon, it can be activated directly through flame contact through the combustion heater, or the saturated activated carbon can be heated by heat exchange through the heat exchange heater, thereby desorbing the enriched exhaust gas and sending the enriched exhaust gas to the enriched exhaust gas treatment unit.

The enriched exhaust gas can determine whether it is a combustible gas. If it is a combustible gas (organic waste gas), it is burned through the combustion furnace, and the combustion tail gas is subjected to exhaust gas absorption or exhaust gas neutralization; if ethanolamine is used as the enriched exhaust gas absorption or the acid-base neutralization of sulfides, the front-end processor completes dust removal, coarse filtration and fine filtration to complete the front-end treatment of the exhaust gas.

[0014] Furthermore, the hopper bracket is fixed with a frame beam through a top frame, and two slide seats are slidably arranged on both sides of the frame beam, a distribution hopper is fixed between the slide seats, and an electric-controlled blanking valve is arranged at the bottom of the distribution hopper; roller seats are fixed at both ends of the frame beam, an electric transmission belt is arranged between the roller seats, the electric transmission belt is fixed to the distribution hopper, and a proximity switch is arranged on the frame beam. When the proximity switch detects the distribution hopper, the distribution hopper is opposite to the top of the buffer hopper; a high-level storage hopper is arranged on the upper part of one end of the frame beam, and a metering rotary valve is arranged at the bottom of the high-level storage hopper; a low-level hopper is arranged below one end of the metal mesh conveyor belt, and the low-level hopper is connected to the high-level storage hopper through a lifting hopper.

[0015] During operation, new activated carbon or activated carbon thermally activated by a heater is fed into a low-level hopper, and the activated carbon is fed into a high-level storage hopper through a lifting hopper. Then, a fixed amount of activated carbon is fed into a distribution hopper through a metering rotary valve, and the distribution hopper is driven to reciprocate linearly by an electric conveyor belt.

The buffer hoppers are bound to the proximity switches one by one. When a buffer hopper is replenished, the controller determines whether it is the selected buffer hopper based on the port to which the proximity switch is connected.

When one group of waste gas treatment units is working, the waste gas intake valve and the treatment exhaust valve of the group are opened, so that the waste gas intake pipe sends the waste gas into the group of waste gas treatment units, and the waste gas after treatment is discharged through the treatment exhaust main pipe; at the same time, the hot blast furnace and the enriched waste gas treatment unit provide activated hot air for the group of waste gas treatment units, and can centrally treat the activated enriched waste gas.

[0017] Furthermore, it also includes a multi-way switching valve and an external treatment module, the structure of the external treatment module is the same as that of the exhaust gas treatment unit; the two output ends of the multi-way switching valve are respectively connected to the exhaust gas intake valve input end through a one-way valve, the two input ends of the multi-way switching valve are connected to the treatment exhaust valve output end, the two input ends of the multi-way switching valve are respectively connected to the manifold through an external exhaust valve, the manifold is serially connected with a first terminal valve group, the input end of the first terminal valve group is connected to the input end of the external treatment module through a second terminal valve group; the output end of the external treatment module is connected to the output end of the first terminal valve group.

[0018] During operation, the two groups of exhaust gas treatment units are connected in series through a multi-way switching valve. After the exhaust gas treatment unit of the front group completes the exhaust gas treatment, it is sent to the exhaust gas inlet valve input end of the exhaust gas treatment unit of the rear group through the treatment exhaust valve, the multi-way switching valve and the one-way valve, and is treated again by the exhaust gas treatment unit of the rear group. After two adsorptions, the low-concentration and high-flow exhaust gas is directly discharged through another treatment exhaust valve, and the external exhaust valve and the first terminal valve group connected to the exhaust gas treatment unit of the rear group; when the first work reaches the set period, it is necessary to switch through the multi-way switching valve. When switching, the exhaust gas treatment unit of the front group is cut off, and the exhaust gas collection main pipe sends the exhaust gas to the exhaust gas treatment unit of the rear group. After completing one treatment, it is connected to the external treatment module through the treatment exhaust valve, the external exhaust valve and the second terminal valve group connected to the exhaust gas treatment unit of the rear group; through the external treatment module After the second group treatment, it is discharged directly; the saturated activated carbon adsorbed in the exhaust gas treatment unit of the front group is discharged, and thermally activated through the second thermal activation component; and the exhaust gas treatment unit of the front group is refilled with new activated carbon; waiting for treatment application again; when the second work reaches the set deadline, the multi-way switching valve is used for switching, and the exhaust gas treatment unit of the rear group is used as the primary exhaust gas treatment, and the exhaust gas treatment unit of the front group is used as the secondary treatment, the external treatment module is removed, and the saturated activated carbon is thermally activated and replaced with new activated carbon; when the third work reaches the set deadline, the multi-way switching valve is used for switching, and the opening and closing of the first terminal valve group and the second terminal valve group are switched, the exhaust gas treatment unit of the front group is subjected to primary exhaust gas treatment, the external treatment module is subjected to secondary exhaust gas treatment, the exhaust gas treatment unit of the rear group is removed, and the saturated activated carbon is thermally activated and replaced with new activated carbon.

[0019] Furthermore, the exhaust main pipe is connected to an activated carbon filter. After the exhaust gas is treated by adsorption by the activated carbon filler, it is then subjected to secondary adsorption by the activated carbon filter, thereby enabling the treated exhaust gas to be treated again.

[0020] Furthermore, a plurality of mesh plates are welded on the inner walls of the upper treatment chamber and the lower treatment chamber, and the aperture of the mesh plates is larger than the particle size of the activated carbon inside the elastic treatment tube. Through the isolation of the mesh plates, a multi-layer mesh structure can be formed inside the elastic treatment module, which can avoid excessive extrusion of the activated carbon and cause the gaps between the activated carbons to be too small.

[0021] Compared with the prior art, the low-concentration, large-flow, and efficient waste gas treatment complete set of equipment of the present invention can ensure that the activated carbon inside the elastic treatment module continues to maintain the purification effect through vibration activation and in-situ thermal activation, thereby extending the working time of the activated carbon; when the activated carbon reaches the purification cycle, the activated carbon is discharged through the bottom discharge, and at the same time, new activated carbon is filled downward from the upper inner side of the elastic treatment module, and the treated waste gas needs to be discharged from the upper part of the elastic treatment module; that is, it needs to pass through new activated carbon before it can be discharged, which can avoid secondary pollution of the treated waste gas when replacing the activated carbon. After the adsorption saturated activated carbon is discharged from the elastic treatment module, it is reactivated by the second thermal activation component and automatically sent to the elastic treatment module again, thereby realizing efficient and automatic waste gas treatment, and can deeply process the enriched pollutant components, and can realize high-efficiency treatment of low-concentration and large-flow waste gas.

After completing one treatment, it is connected to the external treatment module 41 through the treatment exhaust valve 38, the external exhaust valve 43 and the second terminal valve group 46 connected to the exhaust gas treatment unit of the rear group; After being treated by the external treatment module 41, it is directly discharged; the saturated activated carbon adsorbed in the waste gas treatment unit of the front group is discharged, and thermally activated by the second thermal activation component; and the waste gas treatment unit of the front group is refilled with new activated carbon; waiting for treatment application again; when the second work reaches the set deadline, the multi-way switching valve 40 is used for switching, and the waste gas treatment unit of the rear group is used as the primary waste gas treatment, and the waste gas treatment unit of the front group is used as the secondary treatment, the external treatment module 41 is removed, and the saturated activated carbon is thermally activated and replaced with new activated carbon; when the third work reaches the set deadline, the multi-way switching valve 40 is used for switching, and the first terminal valve group 45 and the second terminal valve group 46 are opened and closed for switching, the waste gas treatment unit of the front group is subjected to primary waste gas treatment, and the external treatment module 41 is subjected to secondary waste gas treatment, the waste gas treatment unit of the rear group is removed, and the saturated activated carbon is thermally activated and replaced with new activated carbon.

[0046] The exhaust gas main pipe 39 is connected to an activated carbon filter. After the exhaust gas is adsorbed and treated by the activated carbon filler, it is adsorbed again by the activated carbon filter, so that the exhaust gas can be treated again.

[0047] A plurality of mesh plates 47 are welded on the inner walls of the upper treatment chamber 24 and the lower treatment chamber 25. The aperture of the mesh plate 47 is larger than the particle size of the activated carbon inside the elastic treatment tube 1. Through the isolation of the mesh plate 47, a multi-layer mesh structure can be formed inside the elastic treatment module, which can avoid excessive extrusion of the activated carbon and cause the gaps between the activated carbons to be too small.
