Description

Technical Field

[0001] This utility model relates to the technical field of end-of-life vehicle processing devices, specifically to an integrated device for green recovery and purification of Freon. Background Technology

[0002] With the continuous growth of car ownership, the number of scrapped cars is also increasing. The air conditioning systems in these scrapped cars typically contain refrigerants such as Freon. If Freon is released directly into the atmosphere without treatment, it will damage the ozone layer and exacerbate global warming. Furthermore, some Freon gases are toxic and can harm human health and the environment.

[0003] Currently, there are some shortcomings in the recycling and processing of Freon from scrapped vehicles. Traditional recycling methods often use simple extraction equipment to directly extract Freon into storage containers. This method cannot effectively separate and purify impurities, moisture, and other mixed gases in the Freon, resulting in low purity of the recycled Freon, making it difficult to achieve secondary utilization and causing resource waste.

[0004] Furthermore, existing recycling and purification equipment is mostly independent, with cumbersome operating procedures requiring multiple transfers of Freon, increasing the risk of leakage and labor costs. Therefore, we propose an integrated green Freon recycling and purification device. Utility Model Content

[0005] The purpose of this invention is to provide an integrated device for green recovery and purification of Freon, so as to solve the defects mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A green recycling and purification integrated device for Freon includes a recycling and purification chamber. An air inlet pipe is fixedly installed on the bottom of the chamber, and an air inlet connector is fixedly installed at the inlet end of the air inlet pipe. The recycling and purification chamber contains a filter screen and an activated carbon filter layer for filtering gaseous Freon. A condensation separation chamber for separating moisture and high-boiling-point impurities from the Freon gas is located on one side of the recycling and purification chamber. An adsorption tower for deep adsorption purification of gaseous Freon is located on one side of the condensation separation chamber. A drying chamber for moisture absorption of gaseous Freon is located on one side of the adsorption tower. The adsorption tower and the drying chamber are connected by a suction pump. A recycling pipe for discharging the treated Freon is fixedly installed on the top of the drying chamber, and the recycling pipe is connected to an external storage tank.

[0008] Preferably, a support ring is fixedly installed on the inner wall of the recycling and purification box, and the filter screen and the activated carbon filter layer are both located above the support ring, which is used to support the operation.

[0009] Preferably, the support ring is annular, and a sealing top cover is detachably installed on the top surface of the recycling and purification box, with a sealing ring provided between the sealing top cover and the recycling and purification box.

[0010] Preferably, a drain pipe is fixedly installed on the bottom of the recycling and purification box, and a first valve is fixedly installed on the drain pipe.

[0011] Preferably, a water inlet pipe is fixedly installed on the bottom of the condensation separation box, and a water outlet pipe is fixedly installed on the top of the condensation separation box. The top of the recovery and purification box is connected to the condensation separation box through a gas pipe. A serpentine tube is fixedly installed at the end of the gas pipe located inside the condensation separation box, and a liquid collection box is fixedly installed at the bottom of the serpentine tube. The top of the liquid collection box is connected to the adsorption tower through a gas outlet pipe.

[0012] This feature separates moisture and some high-boiling-point impurities from Freon gas and collects them in a collection box for easy subsequent discharge.

[0013] Preferably, a vertical pipe extending out of the condensation separation box is fixedly installed at the bottom of the liquid collection box, and a second valve is fixedly installed on the vertical pipe.

[0014] Preferably, an addition pipe is fixedly installed on the top of both the adsorption tower and the drying box, and a threaded cap is threadedly connected to the addition pipe. A discharge pipe is fixedly installed on the bottom of both the adsorption tower and the drying box, and a third valve is fixedly installed on the discharge pipe.

[0015] This setting facilitates the subsequent addition of desiccants and adsorbents.

[0016] Preferably, the air inlet of the suction pump is connected to the top chamber of the adsorption tower via a suction pipe, and the air outlet of the suction pump is connected to the bottom chamber of the drying chamber via a guide pipe. A blocking net is fixedly installed in the end pipe of the air outlet installed on the adsorption tower and in the end pipe of the guide pipe installed on the suction pipe.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model establishes a complete and orderly Freon treatment process by setting up a recycling and purification chamber, and sequentially arranging a filter screen, activated carbon filter layer, condensation separation chamber, adsorption tower, and drying chamber inside the chamber. The filter screen and activated carbon filter layer first perform preliminary filtration of gaseous Freon, removing large particulate impurities and some pollutants; the condensation separation chamber separates moisture and high-boiling-point impurities from the gas; the adsorption tower deeply adsorbs residual impurities; and the drying chamber further absorbs moisture, achieving efficient recovery and deep purification of Freon, improving the purity of Freon, creating conditions for its secondary utilization, and increasing the resource recycling rate.

[0019] 2. This utility model achieves convenient discharge of impurities and accumulated liquid generated during the treatment process, as well as convenient addition and replacement of adsorbent and desiccant, by installing a drain pipe in the recycling and purification box, a liquid collection box and corresponding valves in the condensation separation box, and adding and unloading pipes and corresponding valves in the adsorption tower and drying box. This not only ensures the cleanliness of the internal components and maintains stable equipment operation, but also allows for timely replenishment of consumables based on usage, ensuring consistently stable and efficient purification and reducing equipment maintenance difficulty.

[0020] 3. This utility model achieves smooth transmission of Freon gas between various processing stages by rationally setting up connecting pipes and suction pumps between various components, such as gas pipes, gas outlet pipes, suction pipes, and guide pipes, in conjunction with the setting of a barrier net. At the same time, it prevents materials from entering the pipes and affecting equipment operation. The entire device integrates recovery and purification functions, simplifies the operation process, reduces the risk of leakage caused by multiple Freon transfers, lowers labor costs, and has a compact structure, effectively reducing the equipment footprint and purchase cost.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0031] Please see Figures 1-4 This utility model provides a technical solution: an integrated device for green recycling and purification of Freon, including a recycling and purification box 1. An air inlet pipe 10 is fixedly installed on the bottom of the recycling and purification box 1. An air inlet connector 11 is fixedly installed at the air inlet end of the air inlet pipe 10, so that the air inlet pipe 10 is connected to the air conditioning system of the scrapped car. The air inlet connector 11 is convenient and quick to connect, so that the gaseous Freon in the scrapped car can smoothly enter the recycling and purification box 1, providing the prerequisite for subsequent filtration, purification and other operations, and ensuring the smooth progress of the Freon recycling process.

[0032] like Figure 2 As shown, the recovery and purification chamber 1 is equipped with a filter screen 121 and an activated carbon filter layer 122 for filtering gaseous Freon. This allows the gaseous Freon entering the chamber to undergo preliminary filtration. The filter screen 121 can intercept large particulate impurities, and the activated carbon filter layer 122 can adsorb odors and some organic pollutants, thus initially purifying the Freon gas, reducing the processing burden on subsequent equipment such as the condensation and separation chamber 2 and the adsorption tower 3, and improving the overall purification efficiency.

[0033] like Figure 2 As shown, a support ring 12 is fixedly installed on the inner wall of the recycling and purification box 1. The filter screen 121 and the activated carbon filter layer 122 are both located above the support ring 12. The support ring 12 is used for support operation. The support ring 12 is ring-shaped, which enables the support ring 12 to provide stable support for the filter screen 121 and the activated carbon filter layer 122, ensuring that the filter layer will not be displaced or damaged due to gas impact during the Freon gas filtration process, ensuring stable and continuous filtration operation, and extending the service life of the filter layer.

[0034] like Figure 2 As shown, a sealing top cover 13 is detachably installed on the top surface of the recycling and purification chamber 1 by multiple fastening bolts. A sealing ring is provided between the sealing top cover 13 and the recycling and purification chamber 1, so that the sealing top cover 13 can fit tightly with the recycling and purification chamber 1 when closed, effectively preventing Freon gas leakage and ensuring the safety of operators and the environment from pollution. At the same time, the detachable design makes it easy to open the chamber to inspect, clean and replace the internal filter screen 121, activated carbon filter layer 122, etc., which facilitates equipment maintenance.

[0035] like Figure 2 As shown, a drain pipe 14 is fixedly installed on the bottom of the recycling and purification box 1, and a first valve 141 is fixedly installed on the drain pipe 14 to facilitate the periodic cleaning of impurities inside the recycling and purification box 1.

[0036] like Figure 2 As shown, a condensation separation tank 2 for separating moisture and high-boiling-point impurities in Freon gas is installed on one side of the recovery and purification tank 1. A water inlet pipe 20 is fixedly installed on the bottom of the condensation separation tank 2, and a water outlet pipe 21 is fixedly installed on the top of the condensation separation tank 2. The top of the recovery and purification tank 1 is connected to the condensation separation tank 2 via a gas pipe 22. A serpentine pipe 23 is fixedly installed at the end of the gas pipe 22 located inside the condensation separation tank 2. A liquid collection box 24 is fixedly installed at the bottom of the serpentine pipe 23. The top of the liquid collection box 24 is connected to the adsorption tower 3 via an outlet pipe 26, allowing cooling water to flow from the inlet... Water pipe 20 flows into the condensation separation tank 2, carrying away the heat of the Freon gas in the serpentine tube 23 before flowing out from the outlet pipe 21, thus cooling the Freon gas. Gas pipe 22 introduces the pre-filtered Freon gas into the condensation separation tank 2, working in conjunction with the serpentine tube 23 and the liquid collection box 24 to effectively separate moisture and high-boiling-point impurities from the Freon gas, collecting them in the liquid collection box 24 for subsequent discharge. A vertical pipe 25 is fixedly installed at the bottom of the liquid collection box 24, extending out of the condensation separation tank 2. A second valve 251 is fixedly installed on the vertical pipe 25, allowing the moisture and impurities collected in the liquid collection box 24 to be discharged from the tank through the vertical pipe 25. The second valve 251 controls the discharge operation; it opens when it is necessary to discharge liquid and impurities and closes when not needed, preventing gas leakage, ensuring the safety and stability of the condensation separation process, and facilitating the cleaning of the liquid collection box 24.

[0037] like Figure 3As shown, an adsorption tower 3 for deep adsorption and purification of gaseous Freon is provided on one side of the condensation separation box 2. A drying box 30 for moisture absorption of gaseous Freon is provided on one side of the adsorption tower 3. The adsorption tower 3 and the drying box 30 are connected by a suction pump 4. A recovery pipe 31 for the discharge of treated Freon is fixedly installed on the top of the drying box 30. The recovery pipe 31 is connected to an external storage tank to realize the transportation of treated Freon gas to the external storage tank for storage.

[0038] like Figure 3 As shown, both the adsorption tower 3 and the drying chamber 30 are fixedly equipped with an addition pipe 32 at their tops, and a threaded cap 33 is threaded onto the addition pipe 32. Both the adsorption tower 3 and the drying chamber 30 are fixedly equipped with a discharge pipe 34 at their bottoms, and a third valve 35 is fixedly installed on the discharge pipe 34. After the adsorbent in the adsorption tower 3 or the desiccant in the drying chamber 30 has been used for a period of time, new adsorbent or desiccant can be added from the addition pipe 32 by opening the threaded cap 33. When it is necessary to replace the old adsorbent or desiccant, the third valve 35 is opened and the desiccant is discharged from the discharge pipe 34, which facilitates equipment maintenance and consumable replacement, and ensures the adsorption purification and drying effects.

[0039] like Figure 3 and Figure 4 As shown, the inlet of the suction pump 4 is connected to the top of the adsorption tower 3 via a suction pipe 40, and the outlet of the suction pump 4 is connected to the bottom of the drying chamber 30 via a guide pipe 41. Both the outlet pipe 26 installed on the adsorption tower 3 and the guide pipe 41 installed on the suction pipe 40 are fixedly equipped with a blocking net 42, so that the blocking net 42 can intercept the adsorbed particles in the drying chamber 30 and the adsorption tower 3 from entering the guide pipe 41 and the outlet pipe 26, thus avoiding blockage.

[0040] In this embodiment, the adsorption tower 3 is filled with molecular sieves and activated alumina adsorbent, which can be used to deeply adsorb and purify residual impurities and pollutants in Freon gas, thereby improving the purity of Freon; the drying box 30 is equipped with a desiccant, which can be silica gel desiccant. This setting can further remove trace amounts of moisture in Freon gas and ensure the dryness of Freon.

[0041] Finally, it should be noted that the suction pump 4, the corresponding control system, and the external power supply involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle in this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0042] When using the integrated green Freon recovery and purification device of this utility model, first connect the air inlet pipe 10 to the air conditioning system of the scrapped car through the air inlet connector 11 to ensure a tight connection without leakage; then turn on the device to form a negative pressure environment, and gaseous Freon enters the recovery and purification box 1 through the air inlet pipe 10.

[0043] Freon gas first passes through filter screen 121 and activated carbon filter layer 122, where large particulate impurities are intercepted and odors and some organic pollutants are adsorbed. Then, the gas enters condensation separation box 2 through gas pipe 22. In serpentine tube 23, cooling water flows in from water inlet pipe 20 and flows out from water outlet pipe 21, realizing the separation of Freon gas and liquid impurities. Liquid impurities flow into liquid collection box 24. Subsequently, opening the second valve 251 can discharge the impurities in liquid collection box 24.

[0044] After preliminary purification, the Freon gas enters the adsorption tower 3 through the outlet pipe 26, where it is further purified by molecular sieves and activated alumina adsorbent. Then, the suction pump 4 pumps the gas to the drying chamber 30 through the suction pipe 40, where silica gel desiccant removes trace amounts of moisture. Finally, the treated pure Freon gas is transported to an external storage tank through the recovery pipe 31. After a period of use, new adsorbent and desiccant can be added through the addition pipe 32, and old consumables can be discharged through the discharge pipe 34 to complete the maintenance operation.

[0045] 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.
