Description

Technical Field

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

[0002] Coal tar is a by-product in the coking process, composed of various aromatic hydrocarbons. A large amount of waste gas is generated during the processing. These waste gases mainly come from multiple processes such as tar distillation and phenolate decomposition. The use of activated carbon to remove odors in coal tar plants is also an effective treatment method. Activated carbon has the advantages of environmental protection and safety. However, the disadvantages of activated carbon in actual applications are relatively high loss and high usage cost. The current environmental protection treatment equipment for waste gas pollution in coal tar processing is not convenient for continuous activated carbon regeneration. The usage cost of frequently replacing activated carbon is relatively high. The traditional heating method for activated carbon regeneration requires the disassembly of activated carbon, and the activated carbon regeneration is prone to uneven heating. It is also not convenient to automatically detect whether the activated carbon meets the regeneration standard. The adsorption effect after the over-loss regeneration of activated carbon is not good, reducing the economy. It is also easy to cause unqualified waste gas, and it is not convenient to regularly switch the activated carbon adsorption surface, affecting the exhaust efficiency and waste gas adsorption effect.

When there are many broken residues in the activated carbon and the regeneration heating element 5 is blocked, the activated carbon can be replaced in time to ensure the adsorption effect. At the same time, this structure uses the conical structure of the conical heating block 504 to facilitate the insertion of the activated carbon for comprehensive heating. The activated carbon between the two stop meshes 202 below can be continuously heated and carbonized by the conical heating block 504. Cooperating with the two diversion pipes 505, which are respectively externally connected to an air pump and an exhaust pipe, one for intake and one 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 guide through holes 5041 on the exhaust side. As the use cycle of the activated carbon increases and there are more broken pieces in the activated carbon, the guide through holes 5041 on the exhaust side will be blocked. At this time, under the action of air pressure, the conical heating block 504 will press down, squeeze the downward pressure switch 502, and control the indicator light 103 to light up and alarm.

[0035] Among them, the activated carbon extrusion member 4 includes: extrusion sliding shafts 401, magnet rings 4011, and propulsion isolation plates 402. There are two extrusion sliding shafts 401, and the two extrusion sliding shafts 401 are respectively slidably mounted on the stop net 202; a magnet ring 4011 is fixedly sleeved on the front extrusion sliding shaft 401; the end of the extrusion sliding shaft 401 is of an inclined surface structure, and a wire coating is provided on the inclined surface at the end of the extrusion sliding shaft 401; propulsion isolation plates 402 are respectively fixedly installed on the inner sides of the two extrusion sliding shafts 401, and through grooves are provided on the propulsion isolation plates 402; the inner side of the propulsion isolation plate 402 is attached to the rotary switching frame 201; the propulsion isolation plate 402 is used to extrude the activated carbon particles inside the rotary switching frame 201; the activated carbon extrusion member 4 further includes: extrusion tension springs 403. The two extrusion sliding shafts 401 are respectively sleeved with extrusion tension springs 403, and the ends of the two extrusion tension springs 403 are respectively connected to the inner sides of the stop nets 202 on the same side, and the other ends of the two extrusion tension springs 403 are respectively fixedly installed on the sides of the propulsion isolation plate 402; the extrusion release block 302 corresponds to the extrusion sliding shaft 401; by using the activated carbon extrusion member 4, the activated carbon located above can be automatically controlled to fully adhere to the stop net 202, maintaining the comprehensiveness of waste gas adsorption, avoiding the exposed space causing the waste gas to be discharged without being absorbed, maintaining the waste gas treatment quality of this structure, improving the comprehensiveness of waste gas treatment, having a higher utilization rate of activated carbon, and at the same time, it can automatically relieve the extrusion of the activated carbon between the two stop nets 202 at the bottom, facilitating the activated carbon to be scattered on the conical heating block 504 for heating regeneration, improving the heating effect, and also facilitating the air pressure circulation, ensuring the regeneration quality of this structure, making the structure more reasonable. At the same time, in cooperation with the end face sealing member 3, it can be automatically controlled. This structure uses the activated carbon extrusion member 4 to relieve the extrusion of the activated carbon one by one, making it spread and then extruded and adhered to the stop net 202, avoiding the problem that some activated carbon particles are located at the stop net 202 for a long time and have a large adsorption amount, which is likely to cause uneven adsorption amount of the activated carbon after long-term use. This structure can improve the uniformity of the use of activated carbon. The four extrusion sliding shafts 401 above the rotary switching frame 201 are not squeezed and limited by the closing block 301. Under the pulling of the extrusion tension spring 403, the propulsion isolation plate 402 can elastically squeeze and fit the activated carbon particles, promoting the particles to cover the stop net 202. When the rotary switching frame 201 rotates, it also drives the extrusion sliding shaft 401 to rotate. As the extrusion sliding shaft 401 rotates and displaces, it can be squeezed by the extrusion release block 302 and retract inward until the extrusion sliding shaft 401 completely slides to the bottom and the end is attached to the closing block 301. At this time, the activated carbon particles below are no longer squeezed by the propulsion isolation plate 402 and can naturally collapse, facilitating the subsequent comprehensive heating of the conical heating block 504. When the rotary switching frame 201 rotates, the conical heating block 504 with a conical structure can elastically move downward and collapse when being squeezed by the rotary switching frame 201, without causing jamming.

[0036] Embodiment 2. On the basis of Embodiment 1, the alarm test piece 6 includes: a test connection frame 601 and an electromagnet 602. The test connection frame 601 is fixedly installed inside the connection and installation pipe 101 through a bracket; an electromagnet 602 is fixedly installed inside 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 further includes: a power connection elastic sheet 603. Four power connection elastic sheets 603 are fixedly installed on the test connection frame 601, and the four power connection elastic sheets 603 are respectively elastically attached to the inclined surfaces at the ends of the four extrusion sliding shafts 401 above; the power connection elastic sheet 603, the end of the extrusion sliding shaft 401, and the lamp beads of the indicator light 103 are connected in series to the power supply. The alarm test piece 6 can be used to detect the service life of the activated carbon. When the activated carbon is adsorbed saturated and the surface is polluted by the oil and gas in the waste gas, affecting the smooth ventilation, an alarm prompt can be given, which can avoid the problem that the activated carbon particles are overused for a long time and cannot meet the regeneration requirements subsequently, prevent the activated carbon from being over-consumed and saturated, the structure detection is direct, the electromagnet 602 can be used to position the magnet ring 4011, enhance the stability of the propulsion partition plate 402, and prevent the gap of the activated carbon particles extruded by the propulsion partition plate 402 from increasing due to factors such as shaking and leaking waste gas. When it is necessary to test the air flow throughability of the activated carbon, the electromagnet 602 is powered off. At this time, if a large amount of impurities adhere to the surface of the activated carbon, affecting the air flow throughability, under the action of air pressure, the air pressure pushes the propulsion partition plate 402 and stretches the extrusion tension spring 403. At this time, the lamp beads corresponding to the series connection on the indicator light 103 will turn off to prompt to replace the activated carbon. This structure can ensure the service life test of the activated carbon while preventing waste gas leakage.

[0037] Working principle of this embodiment: First, a flange is provided at the end of the connecting installation pipe 101, and bolts are used to connect the exhaust gas outlet pipe. The incoming exhaust gas passes through the four grooves filled with activated carbon particles located above on the rotary switching frame 201 for adsorption work, and the exhaust control pipe 102 exhausts. When the activated carbon particles need to be regenerated, the drive motor 105 drives the rotary switching frame 201 to rotate for switching work. As the rotary switching frame 201 rotates, the closing block 301 fits against the lower stop net 202 in real time for closing to prevent pressure relief. When it is necessary to supplement and add activated carbon particles, first suspend the intake of exhaust gas, rotate and open the two closing covers 104, and then activated carbon particles can be put in according to requirements. When the rotary switching frame 201 rotates, it also drives the extrusion sliding shaft 401 to rotate. As the extrusion sliding shaft 401 rotates and displaces, it can be squeezed by the extrusion release block 302 and retracts inward until the extrusion sliding shaft 401 completely slides to the bottom and its end abuts against the closing block 301, driving the propulsion isolation plate 402 to contract inward. At this time, the activated carbon particles located below are no longer squeezed by the propulsion isolation plate 402 and can naturally collapse, facilitating the subsequent comprehensive heating by the conical heating block 504. If the rotary switching frame 201 continues to rotate, the extrusion sliding shaft 401 located below is no longer blocked by the closing block 301 and can be pulled by the extrusion spring 403 to fit and clamp the activated carbon particles again. During this process, the electromagnet 602 can magnetically attract and position the magnet ring 4011 in real time to enhance the stability of the propulsion isolation plate 402. The activated carbon between the two lower stop nets 202 can be continuously heated and carbonized by the conical heating block 504. Cooperating with the two guide pipes 505, one is externally connected to an air pump and the other to an exhaust pipe, one for 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 through hole 5041 on the exhaust side. As the usage cycle of the activated carbon increases and the activated carbon breaks more, it will block the through hole 5041 on the exhaust side. At this time, under the action of air pressure, the conical heating block 504 will press down, squeeze the pressure switch 502, and control the indicator light 103 to light up for alarm. When it is necessary to test the air flow throughability of the activated carbon, the electromagnet 602 is powered off. At this time, if a large amount of impurities adhere to the surface of the activated carbon and the air flow throughability deteriorates, under the action of air pressure, the air pressure pushes the propulsion isolation plate 402, stretches the extrusion spring 403, and the extrusion sliding shaft 401 also moves accordingly. When the displacement exceeds the elastic adaptation range of the power-on elastic piece 603, the end of the extrusion sliding shaft 401 will separate from the power-on elastic piece 603, and the corresponding light-emitting diodes on the indicator light 103 will go out, indicating to replace the activated carbon.
