Description

Technical Field

[0001] This utility model relates to the field of resin adsorption and desorption technology, specifically to a condensation and recovery device for resin adsorption and desorption. Background Technology

[0002] In waste gas treatment, resin materials are often used to adsorb and recover organic components from the waste gas. Resins exist in granular or fibrous form and have a large surface area and adsorption capacity. When waste gas passes through a resin bed, the molecules of organic components are adsorbed by the resin. After the resin becomes saturated, it needs to be heated with low-pressure steam for desorption. At the same time, the desorbed organic components are condensed, liquefied, and automatically separated into layers with water for recovery.

[0003] As disclosed in CN220824489U, a condensation and recovery device for resin adsorption and desorption includes a housing, a column, an air inlet, a connecting plate, a lifting rod, a driver, a condenser pipe, and a liquid outlet. The inner wall of the housing is equipped with a column, the column having a telescopic blind hole at its center, and the top of the housing has an air inlet. The beneficial effects of this invention are: condensation treatment of waste gas is achieved through the condenser pipe, and the driver moves the condenser pipe up and down within the housing, facilitating control of the internal temperature.

[0004] Although the aforementioned patent allows for the height adjustment of the condenser components, the desorbed gas is not pure organic vapor. It often carries resin debris, sticky oligomers produced by polymer degradation, scale, and other particulate impurities. These substances directly enter the housing and adhere to the complex structure of the condenser tubes and insulation sheets. Over time, they form a serious layer of dirt, greatly reducing heat exchange efficiency. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-4 As shown, this utility model provides a technical solution:

[0025] A condensation and recovery device for resin adsorption and desorption includes a recovery tank 1, with a plurality of hollow cooling plates 2 evenly spaced at the top of the tank. A condensation mechanism is provided between the hollow cooling plates 2 and the recovery tank 1. The condensation mechanism includes cold water pipes 4 that pass horizontally through the hollow cooling plates 2 from top to bottom, and heat-insulating shells 5 symmetrically fixed to the outside of both sides of the recovery tank 1. A diversion pipe 6 is vertically arranged inside the heat-insulating shell 5. The two ends of the cold water pipes 4 are fixedly connected to the two diversion pipes 6 on both sides. A pipe joint 7 is fixedly connected to the outer side of the middle of each diversion pipe 6. The hollow cooling plates 2 are filled with cooling liquid. A sealing ring is provided at the connection between the cold water pipes 4 and the hollow cooling plates 2. An exhaust gas inlet pipe 18 is fixedly connected to the top left side of the recovery tank 1. The output end of the exhaust gas inlet pipe 18 extends to the upper part of the recovery tank 1 and is fixedly connected to a horizontal jet pipe 16. A heat exchange channel 17 is formed between the hollow cooling plates 2, and the output end of the jet pipe 16 faces the heat exchange channel 17. High-pressure water... Pump 3 is fixedly connected to the outer side of the bottom middle of the recycling box 1. A spraying mechanism is provided between the high-pressure water pump 3 and the upper part of the recycling box 1. The spraying mechanism includes a return water pipe 8 fixedly connected to the outer right side of the recycling box 1, and a spray pipe 9 horizontally arranged inside the recycling box 1 and above the jet pipe 16. The input end of the spray pipe 9 is connected to the output end of the high-pressure water pump 3 through the return water pipe 8. The output end of the spray pipe 9 faces the heat exchange channel 17. Support bars 10 are fixedly connected to both sides of the inner wall of the middle of the recycling box 1. The upper ends of the two support bars 10 are detachably connected to the filter plate 11 by bolts. Box doors 12 are hinged to both ends of the middle front of the recycling box 1. Sealing strips are provided at the connection between the box door 12 and the recycling box 1. A liquid level sensor 13 is fixedly connected to the lower left side of the recycling box 1. A water supply pipe 14 is fixedly connected to the upper side of the recycling box 1 near the liquid level sensor 13. A drain pipe 15 is fixedly connected to the bottom left side of the recycling box 1. A controller is provided between the liquid level sensor 13 and the high-pressure water pump 3.

[0026] In this embodiment, by setting a hollow cooling plate 2 filled with cooling liquid and using a cold water pipe 4 that runs through its interior, the temperature of the condensation surface becomes uniform and stable. At the same time, the exposed cold water pipe 4 directly participates in heat exchange, which greatly increases the effective heat exchange area and solves the problem in the prior art where the heat exchange efficiency drops sharply due to the complex structure of the condensation component and the easy adhesion of dirt.

[0027] Furthermore, by setting up a spray rinsing system consisting of a high-pressure water pump 3, a water spray pipe 9, and a filter plate 11, the surface of the hollow cooling plate 2 and the heat exchange channel 17 can be automatically rinsed periodically, effectively removing impurities such as resin debris and sticky oligomers adhering to the heat exchange surface, thus solving the maintenance problem of frequent shutdowns for manual cleaning of condensing components due to scaling and blockage in the prior art.

[0028] Working principle: Desorbed waste gas containing organic components enters the upper part of the recovery box 1 through the waste gas inlet pipe 18 and is sprayed downwards into the heat exchange channel 17 formed by several hollow cooling plates 2 arranged at intervals. At the same time, external refrigerant enters the distribution pipe 6 through the pipe joint 7 and is then distributed to each cold water pipe 4. The refrigerant flowing in the cold water pipe 4 exchanges heat with the hollow cooling plates 2 filled with cooling liquid through the pipe wall, which significantly reduces the surface temperature of the hollow cooling plates 2. At the same time, the part of the cold water pipe 4 exposed in the heat exchange channel 17 also directly contacts the waste gas and exchanges heat. When the waste gas comes into contact with the low temperature surface of the hollow cooling plates 2 and the outer wall of the exposed cold water pipe 4, the organic vapor in the waste gas condenses, changes from gaseous to liquid, and flows downwards along the surface. The condensed liquid organic matter and any condensate that may be contained within it are then absorbed into the liquid. Water drips downwards, and after being filtered by the filter plate 11 to remove solid impurities, it accumulates at the bottom of the recovery tank 1. The liquid level sensor 13 monitors the liquid level in the tank in real time. When the liquid level reaches the set value, the controller automatically starts the high-pressure water pump 3 to pump the liquid at the bottom of the recovery tank 1 into the spray pipe 9 through the return water pipe 8, and sprays it downwards from the spray pipe 9 to rinse the heat exchange channel 17, the surface of the hollow cold conduction plate 2, and the outer wall of the cold water pipe 4 to prevent adhesion and blockage. The rinsed liquid is filtered again by the filter plate 11 and falls back to the bottom of the tank. The recovery tank 1 is replenished with liquid lost due to evaporation or discharge through the water supply pipe 14, and the recovered organic liquid is periodically discharged through the drain pipe 15. Throughout the process, the heat insulation shell 5 effectively reduces the loss of cold energy, the sealing ring ensures the sealing of the connection between the cold water pipe 4 and the hollow cold conduction plate 2, and the door 12 facilitates the maintenance or replacement of the filter plate 11.

[0029] In the specific implementation of this technical solution, the controller can be configured with conventional automatic control units (such as PLC controllers, microcontrollers, or relay control circuits) found in the prior art. Although these control units are not described in detail in the technical solution, they are mature components that can be conventionally selected by those skilled in the art based on actual liquid level and pump control requirements. Their signal acquisition logic and program writing follow well-known technologies in this field and do not affect the implementation of the core innovation of this solution. In practical applications, the controller is mainly used to receive signals from the liquid level sensor and automatically start and stop the high-pressure water pump accordingly. However, its specific type and connection method with the sensor and water pump can be adjusted according to production requirements, all of which fall within the reasonable extension scope of this technical solution.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
