[0023] The waste solution purification process for regenerating isopropyl alcohol provided by the embodiment of the application is described in detail below. The use method includes the following steps: Step one, filtering treatment: connect the connecting pipe 117 with the existing waste solution storage equipment, and simultaneously inject high-temperature solution into the liquid storage frame 110 through the liquid injection pipe and the liquid discharge pipe. The high-temperature gas is continuously transported into the temperature guide frame 202 through the gas transportation pipe 205. Then, the pretreated waste solution is transported into the material transportation pipe 116 through the connecting pipe 117. The waste solution is transported to the top of the filter frame 104 through the material transportation pipe 116. At this time, the driving motor 210 is controlled to start, and the driving motor 210 drives the rotating pipe 212 through the driving gear and the rotating gear 213. The rotating pipe 212 drives the connecting gear 119 to move in the circumferential direction through the adjusting gear 214 under the position limitation of the gear ring 112. The connecting gear 119 drives the bottom plate 115 through the rotating rod 114, and the rotating bottom plate 115 drives the material transportation pipe 116 to rotate. The waste solution is continuously sprayed to different positions on the top of the filter frame 104. The solid impurities in the waste solution are blocked on the top of the filter frame 104 under the action of the filter frame 104. The filtered waste solution flows into the liquid discharge frame 103, and the equipment can quickly filter the waste solution. Step 2, Evaporation Treatment: Using the existing booster pump and pipelines, the filtered waste solution inside the drain frame 103 is injected into the infusion pipe 209. The filtered waste solution is then sprayed through the spray frame 215 onto the top of the rotating plate 217. Simultaneously, driven by the rotating pipe 212, the rotating plate 217 rotates synchronously. The rotating plate 217, in conjunction with the liquid guide strip 218, uses centrifugal force to scatter the filtered waste solution in all directions. Guided by the baffle ring 216, the filtered waste solution is dispersed onto the inner wall of the temperature-conducting frame 202. The filtered waste solution then flows down the inner wall of the temperature-conducting frame 202 and collects between the temperature-conducting frame 202, the insulation ring 201, and the baffle ring 216. The collected filtered waste solution slowly flows through the injection port to the rotating plate 217. The solution then disperses back onto the inner wall of the temperature-conducting frame 202. Under the action of the temperature-conducting plate 203, the temperature of the high-temperature solution is transferred to the temperature-conducting frame 202, allowing the heated frame to evaporate and separate the isopropanol solution from the filtered waste solution. The evaporated isopropanol solution is then rapidly injected into the separation frame 206 under the transport of high-temperature gas. When the isopropanol vapor comes into contact with the lower-temperature inner wall of the separation frame 206, it condenses into droplets. These droplets are then transported to an existing pervaporation membrane separation device for excess water removal, thus completing the purification of the isopropanol solution. This allows the equipment to rapidly process different amounts of waste solution, reducing the amount of equipment used in actual production and lowering actual production costs, enabling the equipment to efficiently perform its intended functions. Step 3, Adjustment and Processing: The intake pipe 118 is connected to the existing cryogenic air delivery equipment, allowing the intake pipe 118, in conjunction with the exhaust strip 120, to deliver cryogenic air to the area below the filter frame 104. Then, with the obstruction of the scraper strip 121, the cryogenic air impacts and is delivered from both sides of the scraper strip 121 to the top of the filter frame 104. During this process, the cryogenic air can expel solid foreign objects blocking the filter frame 104. Simultaneously, the exhaust strip 120 and the scraper strip 121 rotate synchronously with the base plate 115, allowing the solid foreign objects to slide down the surface of the filter frame 104 to the area between the base frame 102 and the outer wall of the drain frame 103. Then, under the pushing force of the pusher strip 105, the filtered solid foreign objects are further... The solution is transported through the collection pipe 106 to the collection frame 107 for centralized processing, ensuring that the solution flowing into the drain frame 103 is free of solid impurities. At the same time, the injected low-temperature air is injected into the exhaust frame 108 under the obstruction of the bottom frame 102, the insulation ring 201 and the rotating plate 217. Then, it is transported through the exhaust pipe 109 through the separation frame 206 and discharged to the outer surface of the separation frame 206. Then, under the separation of the heat dissipation plate 207, the discharged low-temperature air can quickly flow through the outer surface of the separation frame 206, thereby accelerating the temperature transfer of the separation frame 206 and reducing the temperature of the separation frame 206. This ensures that the isopropanol vapor can be efficiently liquefied into droplets, enabling the equipment to perform its intended functions efficiently.

10. A process for purifying waste solution from regenerated isopropanol, characterized in that, The device for purifying and regenerating waste solution of regenerated isopropanol as described in claim 9 includes the following steps: S1. Filtration treatment: Connect to the existing waste solution storage equipment through the connecting pipe (117), and simultaneously circulate high-temperature solution into the storage frame (110) through the injection pipe and the drain pipe, and continuously transport high-temperature gas into the temperature-determining frame (202) through the gas supply pipe (205), and then transport the pretreated waste solution to the inside of the feed pipe (116) through the connecting pipe (117), and then transport the waste solution to the top of the filter frame (104) through the feed port at the bottom of the feed pipe (116). At this time, the drive motor (210) is started by controlling the start of the drive motor (210), so that the drive motor (210) works with the drive gear and the rotating gear (213) to drive the rotating pipe (212). The rotating tube (212) is rotated, and under the position restriction of the gear ring (112), the rotating tube (212) and the adjusting gear (214) can drive the connecting gear (119) to move in the circumferential direction. Then, the connecting gear (119) and the rotating rod (114) can drive the bottom plate (115) to rotate, and the rotating bottom plate (115) can drive the conveying pipe (116) to rotate. Then, the waste solution can be continuously sprayed to different positions on the top of the filter frame (104). Then, under the action of the filter frame (104), the solid foreign matter in the waste solution can be blocked at the top of the filter frame (104), and the filtered waste solution can be concentrated and flow into the drain frame (103). S2, Evaporation Treatment: The waste solution filtered inside the drain frame (103) can be injected into the infusion pipe (209) through the existing booster pump and existing pipeline. Then, the filtered waste solution can be sprayed onto the top of the rotating plate (217) through the spray frame (215). At the same time, driven by the rotating pipe (212), the rotating plate (217) can rotate synchronously. The rotating plate (217), together with the liquid guide strip (218), can scatter the filtered waste solution in all directions under the centrifugal force. Then, under the guidance of the baffle ring (216), the filtered waste solution can be scattered onto the inner wall of the temperature guide frame (202). Then, the filtered waste solution can flow down along the inner wall of the temperature guide frame (202) and collect in the temperature guide frame (202), the insulation ring (201) and Between the baffle rings (216), the collected filtered waste solution will slowly flow to the top of the rotating plate (217) through the injection port, and then re-spread to the inner wall of the temperature-conducting frame (202). At this time, under the action of the temperature-conducting plate (203), the temperature of the high-temperature solution can be transferred to the temperature-conducting frame (202), so that the heated temperature-conducting frame (202) can evaporate and separate the isopropanol solution in the filtered waste solution. The evaporated isopropanol solution can be quickly injected into the separation frame (206) under the transportation of high-temperature gas. When the isopropanol vapor comes into contact with the inner wall of the separation frame (206) with a lower temperature, it will condense into droplets. The collected droplets will be transported to the existing pervaporation membrane separation equipment for the removal of excess water, thereby completing the purification treatment of the isopropanol solution. S3. Adjustment Process: The air inlet pipe (118) is connected to the existing low-temperature air delivery equipment, so that the air inlet pipe (118) and the exhaust strip (120) can deliver low-temperature air to the bottom of the filter frame (104). Then, under the obstruction of the scraper (121), the low-temperature air can be impacted and delivered from both sides of the scraper (121) to the top of the filter frame (104). During this process, the low-temperature air can discharge the solid foreign objects blocking the filter frame (104). At the same time, the exhaust strip (120) and the scraper (121) rotate synchronously with the base plate (115), so that the solid foreign objects can slide down the surface of the filter frame (104) to the outer wall between the bottom frame (102) and the drain frame (103). Then, under the push of the pusher (105), the solid foreign objects are pushed down to the bottom frame (102) and the drain frame (103). The filtered solid foreign matter can be transported to the collection frame (107) through the collection pipe (106) for centralized treatment, ensuring that the solution flowing into the drain frame (103) is free from solid impurities. At the same time, the injected low-temperature air will be injected into the exhaust frame (108) under the obstruction of the bottom frame (102), the insulation ring (201) and the rotating plate (217), and then transported through the exhaust pipe (109) through the separation frame (206) and discharged to the outer surface of the separation frame (206). Then, under the separation of the heat dissipation plate (207), the discharged low-temperature air can flow quickly through the outer surface of the separation frame (206), thereby accelerating the temperature transfer of the separation frame (206) and reducing the temperature of the separation frame (206), ensuring that the isopropanol vapor can be efficiently liquefied into droplets.
