Description

Technical Field

[0001] This invention belongs to the field of macroporous resin adsorption technology, specifically referring to a separation device for macroporous resin adsorption. Background Technology

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

[0003] The existing separation equipment for macroporous resin adsorption has the following problems:

[0004] Existing macroporous resin adsorption separation equipment lacks the ability to regulate the ambient temperature of the macroporous resin adsorption operation. Whether the temperature is too high or too low, it will adversely affect the gas throughput, thereby reducing the adsorption and separation efficiency of macroporous resin for volatile organic compounds (VOCs) in waste gas. Furthermore, traditional macroporous resin adsorption separation equipment also lacks the ability to monitor the adsorption efficiency of macroporous resin in real time during the adsorption operation. Therefore, it cannot meet the current usage requirements for macroporous resin adsorption separation equipment. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, this solution provides a separation device for macroporous resin adsorption that can regulate the ambient temperature of the adsorption operation of macroporous resin and ensure that the macroporous resin is always at the optimal adsorption temperature.

[0006] The technical solution adopted in this solution is as follows: This solution proposes a separation device for macroporous resin adsorption, including a base, a support frame, a thermally controlled adsorption mechanism, and a speed-detecting flow measurement mechanism. The support frame is symmetrically arranged on the upper wall of the base. The thermally controlled adsorption mechanism is located at the end of the support frame away from the base. The speed-detecting flow measurement mechanism is located outside the thermally controlled adsorption mechanism. The thermally controlled adsorption mechanism includes a gas supply mechanism, a water cooling mechanism, a filtration mechanism, and a temperature control mechanism. The gas supply mechanism is located on the side wall of the support frame away from the base. The water cooling mechanism is located at the end of the support frame close to the gas supply mechanism. The filtration mechanism is located inside the gas supply mechanism. The temperature control mechanism is located on the side wall of the filtration mechanism. The speed-detecting flow measurement mechanism includes a wind guide mechanism and a spacing mechanism. The wind guide mechanism is located outside the gas supply mechanism, and the spacing mechanism is located on the side wall of the wind guide mechanism.

[0007] As a further preferred embodiment of the proposed solution, the gas delivery mechanism includes a positioning column, an adsorption cylinder, an exhaust gas pipe, and an exhaust gas pump. The positioning column is located on the side wall of the support frame at one end of the base, on the side of the support frame away from the base. The adsorption cylinder is located on the side of the positioning column away from the support frame. The exhaust gas pump is located on the side of the adsorption cylinder away from the positioning column, with the exhaust end of the exhaust gas pump penetrating inside the adsorption cylinder. The exhaust gas pipe is located at the intake end of the exhaust gas pump. The water cooling mechanism includes a water-cooled annular cylinder, a thermoelectric cooling fin assembly, a distribution box, a water supply pump, a water supply pipe, a water-cooled copper pipe, a circulation pipe, and a heat insulation coating. The water-cooled annular cylinder... Multiple sets of thermoelectric cooling fins are installed at the end of the support frame away from the base, and are located on the side of the water-cooled annulus away from the adsorption cylinder. The cooling end of the thermoelectric cooling fins is located inside the water-cooled annulus. The distribution boxes are symmetrically arranged at both ends of the adsorption cylinder. The water supply pump is located on the bottom wall of the support frame, and the pump's pumping end is connected to the bottom wall of the water-cooled annulus through the support frame. The water supply pipe is connected between the distribution box at the end of the adsorption cylinder away from the water-cooled annulus and the water supply pump's drain end. Multiple sets of water-cooled copper pipes are connected between the distribution boxes through the adsorption cylinder. The circulation pipe is connected between the distribution box at the end of the adsorption cylinder near the water supply pump and the water-cooled annulus. Between the upper walls of the annular cylinder, the heat insulation coating is applied to the side of the water-cooled copper tube away from the adsorption cylinder; the filtration mechanism includes a sliding frame, a filter cylinder, a macroporous resin layer, and telescopic tubes. The sliding frame is slidably disposed on the inner wall of the adsorption cylinder, and the filter cylinder is disposed on the inner wall of the sliding frame. The filter cylinder is a through-type structure. The macroporous resin layer is disposed on the inner wall of the filter cylinder. Multiple sets of telescopic tubes are connected and disposed between the side of the filter cylinder away from the exhaust gas pump and the side of the adsorption cylinder away from the water-cooled annular cylinder; the temperature control mechanism includes a temperature measuring copper frame, a temperature sensor, a temperature measuring spring, an annular adjustable magnet, an annular sliding magnet, and an adjusting spring. A copper frame is installed through the inner wall of the filter cylinder, and a temperature-sensing copper frame is slidably installed on the inner wall of the filter cylinder. The temperature sensor is located on the side of the temperature-sensing copper frame away from the filter cylinder, and the sensing end of the temperature sensor is in contact with the temperature-sensing copper frame. The temperature-sensing spring is located between the filter cylinder and the temperature-sensing copper frame. The annular distance-adjusting electromagnet is located on the inner wall of the adsorption cylinder away from the water-cooled annular cylinder. The annular sliding magnet is located on the side of the filter cylinder away from the temperature sensor. The annular distance-adjusting electromagnet and the annular sliding magnet are arranged opposite to each other. The distance-adjusting spring is located between the inner wall of the adsorption cylinder on the inner wall of the annular distance-adjusting electromagnet and the side wall of the filter cylinder inside the annular sliding magnet.

[0008] During use, an external exhaust gas pipeline is connected to the exhaust gas pipe. The exhaust gas pump draws exhaust gas containing volatile organic compounds into the adsorption cylinder through the exhaust gas pipe. Initially, the temperature sensing spring is extended, and a certain distance is maintained between the temperature sensing copper frame and the filter cylinder. The sliding frame moves the macroporous resin layer to the middle 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 sensing copper frame. The temperature sensor monitors the temperature of the temperature sensing copper frame using its detection end. When the exhaust gas temperature is too high, the porosity of the macroporous resin layer will change, causing the pores to shrink or deform, resulting in… Increased resistance to gas molecules passing through pores reduces gas flow. Lower temperatures slow the movement of gas molecules, further increasing resistance to their passage through the macroporous resin pores and reducing the gas throughput. At this point, the thermoelectric cooling unit cools the water inside the water-cooled annulus via its cooling end. The water pump, through its pumping end, discharges the cooled water from inside the annulus into a distribution box located away from the exhaust gas pump on the support frame. The cooled water in the distribution box flows through water-cooled copper pipes into the distribution box near the water pump on the adsorption cylinder. The water-cooled copper pipes cool the exhaust gas inside the adsorption cylinder, and their temperature increases accordingly. The cooling water flows upwards gradually, with the end of the water-cooled copper pipe furthest from the circulation pipe having the lowest temperature. After the exhaust gas enters the adsorption cylinder, as the distance the exhaust gas travels within the cylinder increases, the contact time between the exhaust gas and the water-cooled copper pipe increases, and the exhaust gas temperature gradually decreases. The annular adjusting electromagnet generates magnetism when energized. The annular adjusting electromagnet and the annular sliding magnet are arranged with opposite poles. The annular adjusting electromagnet is fixed to the inner wall of the adsorption cylinder and magnetically attracts the annular sliding magnet. The annular sliding magnet uses the deformation of the adjusting spring to drive the filter cylinder to move. The filter cylinder slides along the inner wall of the adsorption cylinder away from the exhaust gas pump via a sliding frame, creating a cooling space for the exhaust gas. When the temperature sensor detects that the temperature of the copper frame reaches the user's required temperature, the current flowing into the annular electromagnet remains constant, and the sliding frame stops sliding along the inner wall of the adsorption cylinder. This allows for cooling of the waste gas based on its temperature. Cooling the waste gas to the user's required temperature improves the adsorption efficiency of the macroporous resin layer and reduces the impact of excessively high or low temperatures on the macroporous resin layer. On the one hand, this ensures the waste gas throughput; on the other hand, it improves the adsorption efficiency of the macroporous resin layer for volatile organic compounds in the waste gas. The waste gas adsorbed by the macroporous resin layer is then discharged from the adsorption cylinder through the telescopic tube.

[0009] Preferably, the air guiding mechanism includes an air duct, fan blades, and a test plate. The test plate is located outside the positioning column, and the air duct is rotatably located on the side wall of the test plate outside the adsorption cylinder. The air duct is a through-type structure, and multiple sets of fan blades are located on the inner wall of the end of the air duct away from the test plate. The interval mechanism includes a proximity switch, a sensing block, and a timer. Multiple sets of proximity switches are located on the side wall of the test plate, multiple sets of sensing blocks are located on the side wall of the air duct, and the timer is located on the side wall of the support frame at the end of the base away from the water-cooled annulus cylinder.

[0010] In use, the purified gas inside the adsorption cylinder is discharged into the exhaust duct through the telescopic tube. The gas flow blows the fan blades, which in turn drive the exhaust duct to rotate. Initially, as the exhaust duct rotates, the exhaust duct drives the sensing block to be positioned opposite the proximity switch. The proximity switch detects the sensing block. When the fan blades drive the exhaust duct to rotate, the exhaust duct moves the sensing block away from the proximity switch, and the timer starts counting. When the exhaust duct drives the sensing block to rotate and is aligned with the proximity switch, the proximity switch detects the sensing block, the timer stops counting, and the time for one rotation of the exhaust duct is recorded. The faster the exhaust duct rotates, the shorter the timer's timing, and the faster the airflow velocity discharged through the telescopic tube. This reflects the gas throughput of the macroporous resin layer, thus enabling real-time monitoring of the adsorption efficiency of the macroporous resin layer.

[0011] Specifically, a controller is provided on the side wall of the support frame on one side of the timer.

[0012] The controller is electrically connected to the exhaust gas pump, thermoelectric cooling chip assembly, temperature sensor, annular distance-changing electromagnet, proximity switch and timer respectively.

[0013] Preferably, the temperature sensor is model LM-420.

[0014] Furthermore, the controller is model number SYC89C52RC-401.

[0015] The beneficial effects achieved by this solution using the above structure are as follows:

[0016] Compared with existing technologies, this solution combines a temperature control mechanism with a speed monitoring structure. Through the integrated use of a thermally controlled adsorption mechanism and a speed-detecting flow measurement mechanism, along with the coordinated operation of the gas delivery mechanism, water cooling mechanism, filtration mechanism, temperature control mechanism, air guiding mechanism, and interval mechanism, the adsorption temperature of the macroporous resin layer for waste gas is ensured. This guarantees the waste gas throughput and improves the adsorption efficiency of the macroporous resin layer for volatile organic compounds in the waste gas. Furthermore, the purified flowing gas drives the rotation of the induced draft fan, and the duration of the fan's circumferential rotation is used to monitor the gas flow in the macroporous resin layer. The throughput is monitored in real time, which improves the adsorption efficiency of the macroporous resin layer for volatile organic compounds in the waste gas to a certain extent. The waste gas pump draws the waste gas containing volatile organic compounds into the adsorption cylinder through the waste gas 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 moves 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 waste gas. After the waste gas enters the adsorption cylinder, it first contacts the temperature measuring copper frame. The temperature sensor monitors the temperature of the temperature measuring copper frame using the detection end. Attached Figure Description

[0033] like Figures 1-12 As shown, the separation device for macroporous resin adsorption proposed in this solution includes:

[0034] This solution proposes a separation device for macroporous resin adsorption, comprising a base 1, a support frame 2, a thermally controlled adsorption mechanism 3, and a speed-detecting flow-measuring mechanism 29.

[0035] The gas supply mechanism 4 includes a positioning column 5, an adsorption cylinder 6, an exhaust gas pipe 7, and an exhaust gas pump 39. The positioning column 5 is located on the side wall of the support frame 2 at one end of the base 1, on the side of the support frame 2 away from the base 1. The adsorption cylinder 6 is located on the side of the positioning column 5 away from the support frame 2.

The water-cooled ring cylinder 9 penetrates the support frame 2 away from the base 1. At one end, multiple sets of thermoelectric cooling element groups 10 are installed through the water-cooled annular cylinder 9 on the side away from the adsorption cylinder 6. The cooling end of the thermoelectric cooling element group 10 is located inside the water-cooled annular cylinder 9.

The water pump 12's pumping end is connected to the bottom wall of the water-cooled annular cylinder 9 through the support frame 2. The water supply pipe 13 is connected between the distribution box 11 at the end of the adsorption cylinder 6 away from the water-cooled annular cylinder 9 and the drain end of the water supply pump 12.

The filter cylinder 19 is a through-type structure. The macroporous resin layer 20 is disposed on the inner wall of the filter cylinder 19. Multiple sets of telescopic tubes 21 are connected and disposed between the side of the filter cylinder 19 away from the exhaust gas pump 39 and the side of the adsorption cylinder 6 away from the water-cooled annular cylinder 9; the temperature control mechanism 22 includes a temperature measuring copper frame 23, a temperature sensor 24, a temperature measuring spring 25, an annular adjustable magnet 26, an annular sliding magnet 27, and an adjustable spring 28. The temperature measuring copper frame 23 is a through-type structure. A temperature measuring copper frame 23 is slidably disposed on the inner wall of the filter cylinder 19. The temperature sensor 24 is disposed on the side of the temperature measuring copper frame 23 away from the filter cylinder 19, and the detection end of the temperature sensor 24 is in contact with the temperature measuring copper frame 23. The temperature measuring spring 25 is disposed between the filter cylinder 19 and the temperature measuring copper frame 23. The annular pitch-adjusting electromagnet 26 is disposed on the inner wall of the adsorption cylinder 6 away from the water-cooled annular cylinder 9. The annular sliding magnet 27 is disposed on the side of the filter cylinder 19 away from the temperature sensor 24. The annular pitch-adjusting electromagnet 26 and the annular sliding magnet 27 are arranged opposite to each other. The pitch-adjusting spring 28 is disposed between the inner wall of the adsorption cylinder 6 on the inner wall of the annular pitch-adjusting electromagnet 26 and the side wall of the filter cylinder 19 on the inner side of the annular sliding magnet 27.

[0036] The air guiding mechanism 30 includes an air duct 32, fan blades 33, and a test plate 31. The test plate 31 is located outside the positioning column 5. The air duct 32 is rotatably located on the side wall of the test plate 31 outside the adsorption cylinder 6. The air duct 32 is a through-type structure. Multiple sets of fan blades 33 are located on the inner wall of the end of the air duct 32 away from the test plate 31. The interval mechanism 34 includes a proximity switch 35, a sensing block 36, and a timer 37. Multiple sets of proximity switches 35 are located on the side wall of the test plate 31. Multiple sets of sensing blocks 36 are located on the side wall of the air duct 32. The timer 37 is located on the side wall of the support frame 2 at the end of the base 1 away from the water-cooled ring cylinder 9.

[0037] A controller 38 is provided on the side wall of the support frame 2 on one side of the timer 37.

[0038] The controller 38 is electrically connected to the exhaust gas pump 39, the thermoelectric cooling chip group 10, the temperature sensor 24, the annular distance-changing electromagnet 26, the proximity switch 35, and the timer 37.

[0039] The temperature sensor 24 is model LM-420.

[0040] The controller 38 is model number SYC89C52RC-401.

[0041] In actual 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, the temperature measuring copper frame 23 maintains a certain distance from 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.

[0042] 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 monitors the temperature of the temperature measuring copper frame 23 using the detection end. 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, which will increase the resistance of gas molecules to passing through the pores, thereby reducing the gas passage. The temperature decrease will cause the movement speed of gas molecules to slow down, which will increase the resistance of gas molecules to passing through the macroporous resin pores, thereby reducing the gas passage rate.

[0043] At this time, the controller 38 controls the thermoelectric cooling chip assembly 10 to start. The thermoelectric cooling chip assembly 10 cools the water inside the water-cooled ring cylinder 9 through the cooling end. The controller 38 controls the water supply pump 12 to start. The water supply pump 12 discharges the cooling water inside the water-cooled ring cylinder 9 through the water supply pipe 13 into the distribution box 11 at the end of the support frame 2 away from the exhaust gas pump 39. The cooling water inside the distribution box 11 flows through the water-cooled copper pipe 14 into the distribution box 11 at the end of the adsorption cylinder 6 near the water supply pump 12. The water-cooled copper pipe 14 cools the exhaust gas inside the adsorption cylinder 6. The temperature of the water-cooled copper pipe 14 gradually increases with the flow direction of the cooling water. The temperature of the water-cooled copper pipe 14 is the lowest at the end away from the circulation pipe 15. After the exhaust gas enters the adsorption cylinder 6, as the flow distance of the exhaust gas inside the adsorption cylinder 6 increases, the contact time between the exhaust gas and the water-cooled copper pipe 14 increases, and the temperature of the exhaust gas gradually decreases.

[0044] The controller 38 activates the annular repositioning electromagnet 26, which generates magnetism when energized. The annular repositioning electromagnet 26 and the annular sliding magnet 27 are set with opposite poles. The annular repositioning electromagnet 26 is fixed to the inner wall of the adsorption cylinder 6 and magnetically attracts the annular sliding magnet 27. The annular sliding magnet 27 uses the deformation of the adjusting spring 28 to move the filter cylinder 19. The filter cylinder 19 slides along the inner wall of the adsorption cylinder 6 away from the exhaust gas pump 39 via the sliding frame 18, increasing the cooling space for the exhaust gas. When the temperature sensor 24 detects that the temperature of the temperature measuring copper frame 23 reaches the user's requirement, the annular magnet 26 is activated. The current inside the electromagnet 26 remains constant, and the sliding frame 18 stops sliding along the inner wall of the adsorption cylinder 6, so that it can be cooled according to the temperature of the waste gas. After the waste gas is cooled to the temperature required by the user, the adsorption efficiency of the macroporous resin layer 20 can be improved, and the impact of excessively high or low temperatures on the macroporous resin layer 20 can be reduced. On the one hand, the throughput of the macroporous resin layer 20 for waste gas can be guaranteed, and on the other hand, the adsorption efficiency of the macroporous resin layer 20 for volatile organic compounds in the waste gas can be improved. The waste gas adsorbed by the macroporous resin layer 20 is discharged from the adsorption cylinder 6 through the telescopic pipe 21.

[0045] The purified gas inside the adsorption cylinder 6 is discharged into the exhaust duct 32 through the telescopic tube 21. The gas flow blows the fan blades 33, which in turn drive the exhaust duct 32 to rotate. Initially, when the exhaust duct 32 rotates, the exhaust duct 32 causes the sensing block 36 to be positioned opposite the proximity switch 35. The controller 38 activates the proximity switch 35, which senses the sensing block 36. When the fan blades 33 drive the exhaust duct 32 to rotate, the exhaust duct 32 moves the sensing block 36 away from the proximity switch 35. The controller 38 then starts the timer 37. When the exhaust duct 32 drives the sensing block 36 to rotate... When the proximity switch 35 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 it takes for the exhaust tube 32 to rotate one revolution. The faster the rotation speed of the exhaust tube 32, the shorter the timing time of the timer 37, and the faster the airflow velocity discharged from the telescopic tube 21. This can reflect the gas throughput of the macroporous resin layer 20, and thus monitor the gas throughput efficiency of the macroporous resin layer 20 in real time. When the fan blade 33 drives the exhaust tube 32 to rotate at a slower speed, the controller 38 controls the thermoelectric cooling plate group 10 to adjust the cooling temperature of the water inside the water-cooled ring cylinder 9, thereby regulating the temperature inside the adsorption cylinder 6.

[0046] During the adsorption of volatile organic compounds by the macroporous resin layer 20, the adsorption process releases heat and causes 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 adsorption, it comes into contact with the temperature measuring copper frame 23. 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 adjusting electromagnet 26 magnetically attracts the annular sliding magnet 27. The annular sliding magnet 27 uses the deformation and shortening of the adjusting spring 28 to drive the sliding frame 18 to slide along the inner wall of the adsorption cylinder 6, thereby reducing the temperature of the macroporous resin layer 20 and ensuring that it is always at the optimal adsorption temperature. The above operation can be repeated for the next use.
