[0001] The invention belongs to the technical field of macroporous resin adsorption, and specifically refers to separation equipment for macroporous resin adsorption. Background Art

[0002] Macroporous resin adsorption separation equipment plays an important role in waste gas treatment, especially in the adsorption and separation of volatile organic compounds (VOCs). Macroporous adsorption resin is a type of polymer adsorption resin that does not contain exchange groups and has a macroporous structure. It has a good macroporous network structure and a large specific surface area.

[0003] The existing separation equipment for macroporous resin adsorption has the following problems: Existing separation equipment for macroporous resin adsorption does not have the ability to regulate the temperature of the macroporous resin adsorption operation environment. Whether the temperature is too high or too low, it will have an adverse effect on the gas passage rate, thereby reducing the adsorption and separation efficiency of the macroporous resin for volatile organic compounds (VOCs) in the exhaust gas. In addition, traditional separation equipment for macroporous resin adsorption does not have the ability to monitor the adsorption efficiency of the macroporous resin during the adsorption operation in real time. Therefore, it cannot meet the existing use requirements for separation equipment for macroporous resin adsorption. Summary of the invention

The thermoelectric refrigeration sheet group is penetrated at one end of the support frame away from the base, and multiple groups of the thermoelectric refrigeration sheet group are penetrated and arranged on the side of the water-cooled ring tube away from the adsorption tube. The cooling end of the thermoelectric refrigeration sheet group is arranged inside the water-cooled ring tube. The diverter box is symmetrically arranged at both ends of the adsorption tube. The water supply pump is arranged on the bottom wall of the support frame. The water supply pump pumping end penetrates the support frame and is connected with the bottom wall of the water-cooled ring tube. The water supply pipe is connected between the diverter box at one end of the adsorption tube away from the water-cooled ring tube and the drainage end of the water supply pump. Multiple groups of the water-cooled copper tubes penetrate the adsorption tube and are connected between the diverter boxes. The circulation pipe is connected between the diverter box at one end of the adsorption tube close to the water supply pump and the water-cooled The heat-insulating coating is arranged on the side of the water-cooled copper tube away from the adsorption tube between the upper walls of the annular cylinder; the filtering mechanism comprises a sliding frame, a filter tube, a macroporous resin layer and a telescopic tube, the sliding frame is slidably arranged on the inner wall of the adsorption tube, the filter tube is arranged on the inner wall of the sliding frame, the filter tube is through-arranged, the macroporous resin layer is arranged on the inner wall of the filter tube, and multiple groups of telescopic tubes are connected and arranged between the side of the filter tube away from the exhaust gas pump and the side of the adsorption tube away from the water-cooled annular cylinder; the temperature control mechanism comprises a temperature measuring copper frame, a temperature sensor, a temperature measuring spring, an annular distance adjustment electromagnet, an annular sliding magnet and a distance adjustment spring, the temperature measuring The copper frame penetrates the inner wall of the filter cartridge, the temperature measuring copper frame is slidably arranged on the inner wall of the filter cartridge, the temperature sensor is arranged on the side of the temperature measuring copper frame away from the filter cartridge, the detection end of the temperature sensor is in contact with the temperature measuring copper frame, the temperature measuring spring is arranged between the filter cartridge and the temperature measuring copper frame, the annular distance changing electromagnet is arranged on the inner wall of the adsorption cartridge away from the water-cooling ring cartridge, the annular sliding magnet is arranged on the side of the filter cartridge away from the temperature sensor, the annular distance changing electromagnet and the annular sliding magnet are arranged opposite to each other, and the distance adjusting spring is arranged between the inner wall of the adsorption cartridge on the inner wall of the annular distance changing electromagnet and the side wall of the filter cartridge on the inner side of the annular sliding magnet.

[0007] When in use, the external exhaust pipe is connected to the exhaust pipe, and the exhaust pump draws the exhaust gas containing volatile organic compounds into the adsorption cylinder through the exhaust pipe. In the initial state, the temperature measuring spring is extended, and a certain distance is maintained between the temperature measuring copper frame and the filter cylinder. The sliding frame drives the macroporous resin layer to be located in the middle part of the adsorption cylinder. The position of the filter cylinder inside the adsorption cylinder is adjusted according to the temperature of the exhaust gas. After the exhaust gas enters the adsorption cylinder, it first contacts the temperature measuring copper frame. The temperature sensor uses the detection end to monitor the temperature of the temperature measuring copper frame. When the exhaust temperature is too high, the pore structure of the macroporous resin layer will change, and the pores will shrink or deform, resulting in The resistance of gas molecules passing through the pores increases, thereby reducing the passage of gas. The decrease in temperature will slow down the movement of gas molecules, increase the resistance of gas molecules passing through the pores of the macroporous resin, and reduce the gas passage rate. At this time, the thermoelectric refrigeration plate group cools the water inside the water-cooled ring cylinder through the cooling end, and the water supply pump discharges the cooled water inside the water-cooled ring cylinder through the water supply pipe into the diverter box at the end of the support frame away from the exhaust gas pump. The cooling water inside the diverter box passes through the water-cooled copper pipe and flows into the diverter box at the end of the adsorption cylinder near the water supply pump. The water-cooled copper pipe cools the exhaust gas inside the adsorption cylinder, and the temperature of the water-cooled copper pipe changes with The cooling water gradually rises in the flow direction, and the temperature of the end of the water-cooled copper tube farthest from the circulation tube is the lowest. After the exhaust gas enters the adsorption tube, as the flow distance of the exhaust gas inside the adsorption tube increases, the contact time between the exhaust gas and the water-cooled copper tube increases, and the temperature of the exhaust gas gradually decreases. The annular pitch-changing electromagnet is energized to generate magnetism. The annular pitch-changing electromagnet and the annular sliding magnet are set with opposite poles. The annular pitch-changing electromagnet is fixed on the inner wall of the adsorption tube and absorbs the annular sliding magnet by magnetic force. The annular sliding magnet uses the deformation of the pitch-adjusting spring to drive the filter tube to move. The filter tube slides along the inner wall of the adsorption tube through the sliding frame away from the exhaust pump, and the cooling space of the exhaust gas is Increase, when the temperature sensor detects that the temperature of the temperature measuring copper frame reaches the user's requirement, the current passed into the annular pitch-changing electromagnet remains unchanged, and the sliding frame stops sliding along the inner wall of the adsorption tube, so that the exhaust gas can be cooled according to its temperature. After the exhaust gas is cooled to the temperature required by the user, the adsorption efficiency of the macroporous resin layer on it can be improved, and the impact of excessively high or low temperature on the macroporous resin layer can be reduced. On the one hand, the pass rate of the exhaust gas can be guaranteed, and on the other hand, the adsorption efficiency of the macroporous resin layer on volatile organic compounds in the exhaust gas can be improved. The exhaust gas adsorbed by the macroporous resin layer is discharged from the interior of the adsorption tube through the telescopic tube.

[0009] When in use, the purified gas inside the adsorption cylinder is discharged into the induced draft tube through the telescopic tube, and the gas flow blows the fan blades, and the fan blades drive the induced draft tube to rotate under the action of the airflow. In the initial state, the induced draft tube is rotated, and the induced draft tube drives the sensing block to be set relative to the proximity switch, and the proximity switch senses the sensing block. When the fan blades drive the induced draft tube to rotate, the induced draft tube drives the sensing block away from the proximity switch, and the timer starts timing. When the induced draft tube drives the sensing block to rotate relative to the proximity switch, the proximity switch senses the sensing block, and the timer stops timing and records the time of one rotation of the induced draft tube. The faster the rotation speed of the induced draft tube, the shorter the timing time of the timer, and the faster the airflow velocity discharged from the telescopic tube, thereby reflecting the gas passage rate of the macroporous resin layer, and then the adsorption efficiency of the macroporous resin layer can be monitored in real time.

[0010] Specifically, a controller is provided on the side wall of the support frame on one side of the timer.

[0011] Wherein, the controller is electrically connected to the exhaust gas pump, the thermoelectric cooling sheet group, the temperature sensor, the annular distance changing electromagnet, the proximity switch and the timer respectively.

[0012] Preferably, the model of the temperature sensor is LM-420.

[0013] Furthermore, the model of the controller is SYC89C52RC-401.

[0014] The beneficial effects achieved by adopting the above structure are as follows: Compared with the prior art, this solution adopts a combination of a temperature control mechanism and a speed monitoring structure. By setting up a heat-controlled adsorption mechanism and a speed-detecting flow-through mechanism, the adsorption temperature of the waste gas by the macroporous resin layer is guaranteed under the coordinated use of the gas transmission mechanism, the water cooling mechanism, the filtering mechanism, the temperature control mechanism, the air guide mechanism and the spacing mechanism. On the one hand, the passing rate of the waste gas can be guaranteed, and on the other hand, the adsorption efficiency of the macroporous resin layer on volatile organic compounds in the waste gas can be improved. The purified flowing gas is used to drive the induced draft tube to rotate, and the gas of the macroporous resin layer is regulated by the circumferential rotation time of the induced draft tube. The flow rate is monitored in real time, which improves the adsorption efficiency of the macroporous resin layer on volatile organic compounds in the exhaust gas to a certain extent. The exhaust pump draws the exhaust gas containing volatile organic compounds into the adsorption cylinder through the exhaust pipe. In the initial state, the temperature measuring spring is extended, and a certain distance is maintained between the temperature measuring copper frame and the filter cylinder. The sliding frame drives the macroporous resin layer to the middle part of the adsorption cylinder. The position of the filter cylinder inside the adsorption cylinder is adjusted according to the temperature of the exhaust gas. After the exhaust gas enters the adsorption cylinder, it first contacts the temperature measuring copper frame. The temperature sensor uses the detection end to monitor the temperature of the temperature measuring copper frame. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] A controller 38 is provided on the side wall of the support frame 2 on one side of the timer 37 .

[0025] The controller 38 is electrically connected to the exhaust pump 39 , the thermoelectric cooling sheet group 10 , the temperature sensor 24 , the annular distance changing electromagnet 26 , the proximity switch 35 and the timer 37 , respectively.

[0026] The model of the temperature sensor 24 is LM-420.

[0027] The model of the controller 38 is SYC89C52RC-401.

[0028] When in use, the external exhaust pipe 7 is connected to the exhaust pipe 7, and the exhaust pump 39 draws the exhaust gas containing volatile organic compounds into the adsorption cylinder 6 through the exhaust pipe 7. In the initial state, the temperature measuring spring 25 is extended, and a certain distance is maintained between the temperature measuring copper frame 23 and the filter cylinder 19, and the sliding frame 18 drives the macroporous resin layer 20 to be located in the middle part of the adsorption cylinder 6; The position of the filter cartridge 19 inside the adsorption cartridge 6 is adjusted according to the temperature of the exhaust gas. After the exhaust gas enters the adsorption cartridge 6, it first contacts the temperature measuring copper frame 23. The controller 38 controls the temperature sensor 24 to start. The temperature sensor 24 uses the detection end to monitor the temperature of the temperature measuring copper frame 23. When the exhaust gas temperature is too high, the pore structure of the macroporous resin layer 20 will change, the pores will shrink or deform, resulting in an increase in the resistance of gas molecules passing through the pores, thereby reducing the passage of gas. The temperature reduction will slow down the movement speed of gas molecules, increase the resistance of gas molecules passing through the pores of the macroporous resin, and thus reduce the gas passage rate. At this time, the controller 38 controls the thermoelectric refrigeration plate group 10 to start, and the thermoelectric refrigeration plate group 10 cools the water inside the water-cooled ring tube 9 through the refrigeration end. The controller 38 controls the water supply pump 12 to start, and the water supply pump 12 discharges the cooling water inside the water-cooled ring tube 9 through the water supply pipe 13 through the pumping end into the diverter box 11 at the end of the support frame 2 far away from the exhaust gas pump 39. The cooling water inside the diverter box 11 passes through the water-cooled copper tube 14 and flows into the diverter box 11 at the end of the adsorption tube 6 close to the water supply pump 12. The water-cooled copper tube 14 cools the exhaust gas inside the adsorption tube 6. The temperature of the water-cooled copper tube 14 gradually increases with the flow direction of the cooling water. The temperature of the water-cooled copper tube 14 is the lowest at the end far away from the circulation tube 15. After the exhaust gas enters the adsorption tube 6, as the flow distance of the exhaust gas inside the adsorption tube 6 increases, the contact time of the exhaust gas with the water-cooled copper tube 14 increases, and the temperature of the exhaust gas gradually decreases. The controller 38 controls the annular distance-changing electromagnet 26 to start, and the annular distance-changing electromagnet 26 generates magnetism when it is energized. The annular distance-changing electromagnet 26 and the annular sliding magnet 27 are arranged with opposite poles. The annular distance-changing electromagnet 26 is fixed on the inner wall of the adsorption cylinder 6 and adsorbs the annular sliding magnet 27 by magnetic force. The annular sliding magnet 27 drives the filter cylinder 19 to move by the deformation of the distance-adjusting spring 28. The filter cylinder 19 slides along the inner wall of the adsorption cylinder 6 away from the exhaust pump 39 through the sliding frame 18, and the cooling space of the exhaust gas is increased. When the temperature sensor 24 detects that the temperature of the temperature measuring copper frame 23 reaches the user's needs, the exhaust gas is introduced into the annular The current inside the distance-changing electromagnet 26 remains unchanged, and the sliding frame 18 stops sliding along the inner wall of the adsorption tube 6, so that the exhaust gas can be cooled according to its temperature. After the exhaust gas is cooled to the temperature required by the user, the adsorption efficiency of the macroporous resin layer 20 can be improved, and the influence of excessively high or too low temperature on the macroporous resin layer 20 can be reduced. On the one hand, the passing rate of the exhaust gas by the macroporous resin layer 20 can be guaranteed, and on the other hand, the adsorption efficiency of the volatile organic compounds in the exhaust gas by the macroporous resin layer 20 can be improved. The exhaust gas adsorbed by the macroporous resin layer 20 is discharged from the interior of the adsorption tube 6 through the telescopic tube 21; The purified gas inside the adsorption cylinder 6 is discharged into the induced draft cylinder 32 through the telescopic tube 21, and the gas flow blows the fan blades 33. The fan blades 33 drive the induced draft cylinder 32 to rotate under the action of the airflow. In the initial state, the induced draft cylinder 32 is rotated, and the induced draft cylinder 32 drives the sensing block 36 to be arranged opposite to the proximity switch 35. The controller 38 controls the proximity switch 35 to start, and the proximity switch 35 senses the sensing block 36. When the fan blades 33 drive the induced draft cylinder 32 to rotate, the induced draft cylinder 32 drives the sensing block 36 away from the proximity switch 35. The controller 38 controls the timer 37 to start timing. When the induced draft cylinder 32 drives the sensing block 36 to rotate When it is opposite to the proximity switch 35, the proximity switch 35 senses the sensing block 36, the timer 37 stops timing and records the time for the induced draft tube 32 to rotate one circle. The faster the rotation speed of the induced draft tube 32 is, the shorter the timing time of the timer 37 is, and the faster the flow rate of the airflow discharged from the telescopic tube 21 is, so that the gas passing rate of the macroporous resin layer 20 can be reflected, and then the gas passing efficiency of the macroporous resin layer 20 can be monitored in real time. When the fan blades 33 drive the induced draft tube 32 to rotate at a lower speed, the controller 38 controls the thermoelectric cooling sheet group 10 to adjust the cooling temperature of the water inside the water-cooling ring tube 9, and regulates the temperature inside the adsorption tube 6; During the process of adsorption of volatile organic compounds by the macroporous resin layer 20, the adsorption process will release heat and cause the temperature to rise. It is necessary to control the appropriate adsorption temperature to ensure that the macroporous resin layer 20 can maintain the best adsorption effect. When the macroporous resin layer 20 releases heat during the adsorption process, the macroporous resin layer 20 contacts the temperature measuring copper frame 23, and the temperature sensor 24 monitors the temperature of the temperature measuring copper frame 23 in real time. When the temperature of the temperature measuring copper frame 23 rises, the annular distance adjustment electromagnet 26 absorbs the annular sliding magnet 27 through magnetic force. The annular sliding magnet 27 uses the deformation and shortening of the distance adjustment spring 28 to drive the sliding frame 18 to slide along the inner wall of the adsorption tube 6, thereby reducing the temperature of the macroporous resin layer 20 and ensuring that it is always at the best adsorption temperature. Repeat the above operation when using it next time.
