Description

Technical Field

[0001] The invention relates to the technical field of activated carbon waste gas adsorption, in particular to an environmental protection treatment device for waste gas pollution used in coal tar processing. Background Art

[0002] Coal tar is a by-product of the coking process and is composed of various aromatic hydrocarbons. A large amount of waste gas is generated during the processing. These waste gases mainly come from tar distillation, phenol salt decomposition and other processes. Activated carbon deodorization in coal tar plants is also an effective treatment method. Activated carbon has the advantages of environmental protection and safety. The disadvantages of activated carbon in actual application are high loss and high cost of use. The current environmental protection treatment equipment for waste gas pollution used in coal tar processing is not convenient for continuous activated carbon regeneration, and the cost of frequent replacement of activated carbon is high. The traditional activated carbon regeneration heating method requires the disassembly of activated carbon, and the regeneration of activated carbon is prone to uneven heating. It is also not convenient to automatically detect whether the activated carbon meets the regeneration standard. The adsorption effect of activated carbon after excessive loss is poor, which reduces the economy and easily causes waste gas to fail to meet the standards. It is also not convenient to regularly switch the activated carbon adsorption surface, affecting the exhaust efficiency and waste gas adsorption effect.

At the same time, the end face closing piece 3 can be used to seal the stop net 202 where the activated carbon undergoing heating regeneration is located, which can prevent leakage and improve the sealing effect.

[0034] Among them, the regeneration heating element 5 includes a heating connection tube 501 and a push-down switch 502. There are two heating connection tubes 501, and the structures on the two heating connection tubes 501 are the same; the two heating connection tubes 501 are respectively threadedly connected to the connecting and mounting tube 101; the inner sides of the two heating connection tubes 501 are respectively fixedly installed with push-down switches 502; the two heating connection tubes 501 are respectively located on the sides of the two propulsion isolation plates 402; the push-down switch 502 is electrically connected to the lamp bead on the indicator light 103; the regeneration heating element 5 also includes: a retraction spring 503, a conical heating block 504, a conducting hole 5041 and a guide tube 505.

The two regenerative heating elements 5 can realize ventilation and accelerate the discharge of impurities. At the same time, the regenerative heating element 5 used can detect the activated carbon waste residue and detect the broken activated carbon residue when the activated carbon is broken. When there is a lot of slag and it blocks the regeneration heating element 5, the activated carbon can be replaced in time to ensure the adsorption effect. At the same time, the structure uses the conical structure of the conical heating block 504 to facilitate the insertion of activated carbon for comprehensive heating. The activated carbon between the two stop nets 202 below can be continuously heated and carbonized by the conical heating block 504, and cooperates with two guide pipes 505, which are respectively connected to an external air pump and an exhaust pipe, one for air intake and the other for exhaust. At this time, the air can accelerate the combustion of the activated carbon, and the impurity powder on the activated carbon can be discharged from the conducting hole 5041 on the exhaust side. As the use cycle of the activated carbon increases, when the activated carbon is broken more, it will block the conducting hole 5041 on the exhaust side. At this time, under the action of air pressure, the conical heating block 504 will be pressed down, squeezing the down-press switch 502, and the control indicator light 103 will light up to alarm.

[0035] The activated carbon extrusion member 4 comprises: an extrusion slide shaft 401, a magnet ring 4011 and a push isolation plate 402. Two extrusion slide shafts 401 are provided, and the two extrusion slide shafts 401 are respectively slidably mounted on the stopper net 202; a magnet ring 4011 is fixedly sleeved on the front extrusion slide shaft 401; the end of the extrusion slide shaft 401 is an inclined structure, and the inclined surface of the end of the extrusion slide shaft 401 is provided with a conductor coating; the inner sides of the two extrusion slide shafts 401 are respectively fixedly installed with push isolation plates 402, and through grooves are provided on the push isolation plates 402; the inner sides of the push isolation plates 402 are attached to the rotating switching frame 201; the push isolation plates 402 are used to extrude the activated carbon particles inside the rotating switching frame 201; the activated carbon extrusion member 4 also The invention comprises: an extrusion tension spring 403, two extrusion slide shafts 401 are respectively sleeved with an extrusion tension spring 403, and the ends of the two extrusion tension springs 403 are respectively connected to the inner side of the stop net 202 on the same side, and the other ends of the two extrusion tension springs 403 are respectively fixedly installed on the side of the push isolation plate 402; the extrusion release block 302 corresponds to the extrusion slide shaft 401; the use of the activated carbon extrusion piece 4 can automatically control the activated carbon located above to fully fit the stop net 202, maintain the comprehensiveness of exhaust gas adsorption, avoid the exhaust gas being discharged without being absorbed due to the exposed space, maintain the exhaust gas treatment quality of the structure, improve the comprehensiveness of exhaust gas treatment, and increase the utilization rate of activated carbon. At the same time, it can automatically control the activated carbon located between the two stop nets 202 at the bottom. The activated carbon is released from extrusion, so that the activated carbon can be spread on the conical heating block 504 for heating and regeneration, which improves the heating effect and facilitates the circulation of air pressure, ensuring the regeneration quality of the structure. The structure is more reasonable and can be automatically controlled in conjunction with the end face sealing member 3. The structure uses the activated carbon extrusion member 4 to release the extrusion of the activated carbon one by one, so that it can be extruded and fitted to the stopper net 202 after being spread, so as to avoid local activated carbon particles being in the stopper net 202 for a long time, resulting in a large adsorption amount, and long-term use is likely to cause uneven adsorption of activated carbon. The structure can improve the uniformity of the use of activated carbon. The four extrusion slide shafts 401 located above the rotating switching frame 201 are not squeezed and limited by the sealing block 301. When the extrusion tension spring 403 is pulled When the rotating switching frame 201 rotates, the extrusion slide shaft 401 is also driven to rotate. As the extrusion slide shaft 401 rotates and moves, it can be squeezed by the extrusion release block 302 and retracted inward until the extrusion slide shaft 401 completely slides to the bottom and the end is attached to the closing block 301. At this time, the activated carbon particles located below are no longer squeezed by the pushing isolation plate 402 and can collapse naturally, which is convenient for the subsequent conical heating block 504 to be fully heated. When the rotating switching frame 201 rotates, the conical heating block 504 with a conical structure can elastically move downward and collapse when squeezed by the rotating switching frame 201, and will not cause jamming.

[0036] Embodiment 2, on the basis of embodiment 1, the alarm test piece 6 comprises: a test connection frame 601 and an electromagnet 602, the test connection frame 601, the test connection frame 601 is fixedly mounted on the inner side of the connection mounting tube 101 through a bracket; an electromagnet 602 is fixedly mounted on the inner side of the test connection frame 601; the electromagnet 602 is used to magnetically attract the four magnet rings 4011 above; the test connection frame 601 is an arc-shaped structure; the alarm test piece 6 also comprises: a power-connecting spring 603, four power-connecting springs 603 are fixedly mounted on the test connection frame 601, and the four power-connecting springs 603 are elastically attached to the inclined surfaces of the ends of the four extrusion slide shafts 401 above respectively; the power-connecting spring 603, the end of the extrusion slide shaft 401 and the lamp bead of the indicator light 103 are connected in series with a power supply, and the alarm test piece 6 can be used to detect the life of activated carbon, and when the activated carbon is saturated with adsorption and the surface is When the oil and gas pollution in the exhaust gas affects the smooth ventilation, an alarm can be issued to avoid the long-term excessive use of activated carbon particles and the subsequent inability to meet the regeneration needs, and to prevent excessive loss and saturation of activated carbon. The structure detection is direct, and the electromagnet 602 can be used to position the magnet ring 4011 to enhance the stability of the propulsion isolation plate 402 to prevent factors such as shaking from causing an increase in the gap between the activated carbon particles squeezed by the propulsion isolation plate 402 and leakage of exhaust gas. When it is necessary to test the airflow permeability of the activated carbon, the electromagnet 602 is powered off. At this time, if a large amount of impurities are attached to the surface of the activated carbon, affecting the airflow permeability, the air pressure pushes the propulsion isolation plate 402 under the action of air pressure, stretching the extrusion tension spring 403. At this time, the corresponding series-connected lamp beads on the indicator light 103 will go out to prompt the replacement of the activated carbon. This structure can ensure the life test of the activated carbon while preventing exhaust gas leakage.

[0037] The working principle of this embodiment is as follows: first, a flange is provided at the end of the connecting and mounting pipe 101, and the exhaust gas outlet pipe is connected with bolts. The incoming exhaust gas passes through the four grooves filled with activated carbon particles on the upper part of the rotating switching frame 201 for adsorption. The exhaust control pipe 102 is exhausted. When the activated carbon particles need to be regenerated, the driving motor 105 drives the rotating switching frame 201 to rotate for switching. As the rotating switching frame 201 rotates, the sealing block 301 is in real time attached to the stopper net 202 at the bottom for sealing to prevent pressure relief. When it is necessary to add activated carbon particles, the exhaust gas intake is first suspended, and the two sealing covers 104 are rotated to open. The activated carbon particles are added according to the demand. When the rotating switching frame 201 rotates, the extrusion slide shaft 401 is also driven to rotate. As the extrusion slide shaft 401 rotates and moves, it can be squeezed by the extrusion release block 302 and retract inward until the extrusion slide shaft 401 completely slides to the bottom and the end is attached to the closing block 301, driving the push isolation plate 402 to retract inward. At this time, the activated carbon particles located below are no longer squeezed by the push isolation plate 402 and can collapse naturally, which is convenient for the subsequent conical heating block 504 to fully heat. If the rotating switching frame 201 continues to rotate, the extrusion slide shaft 401 at the bottom is no longer squeezed by the closing block 301 and can be pulled by the extrusion tension spring 403. The activated carbon particles are clamped again. During this process, the electromagnet 602 can be used to magnetically position the magnet ring 4011 in real time to enhance the stability of the isolation plate 402. The activated carbon between the two stop nets 202 below can be continuously heated and carbonized by the conical heating block 504. Two guide tubes 505 are used to connect the air pump and the exhaust pipe respectively, one for air intake and the other for exhaust. At this time, the air can accelerate the combustion of the activated carbon, and the impurity powder on the activated carbon can be discharged from the conduction hole 5041 on the exhaust side. As the use cycle of the activated carbon increases, the activated carbon will be broken into pieces and will block the conduction hole 5041 on the exhaust side. At this time, Under the action of pressure, the conical heating block 504 will be pressed down, squeezing the down-pressing switch 502, and the control indicator light 103 will light up to alarm; when it is necessary to test the airflow permeability of the activated carbon, the electromagnet 602 will be powered off. At this time, if a large amount of impurities are attached to the surface of the activated carbon, the airflow permeability will deteriorate, affecting the airflow permeability. Under the action of air pressure, the air pressure pushes the isolation plate 402, lengthens the extrusion tension spring 403, and the extrusion slide shaft 401 also moves with it. When the displacement exceeds the standard, it exceeds the elastic adaptation range of the power-connected spring 603. At this time, the end of the extrusion slide shaft 401 will be separated from the power-connected spring 603, and the corresponding series-connected lamp bead on the indicator light 103 will go out, prompting the replacement of the activated carbon.
