Description
Technical Field
[0001] This utility model relates to the field of difluorochloroethane production technology, specifically to a difluorochloroethane dehydration phase separation device. Background Technology
[0002] Dichlorofluoroethane is a colorless liquid with a slightly pungent odor. It is stable at room temperature, insoluble in water, but soluble in organic solvents such as alcohols and ethers. Due to its moderate boiling point and good refrigeration properties, dichlorofluoroethane is widely used as a refrigerant, especially in air conditioning and refrigeration equipment. In the chemical industry, it is also commonly used as a solvent, particularly in cleaning and degreasing processes. Furthermore, it can be used as a solvent in polymer manufacturing. Besides its refrigeration and solvent applications, dichlorofluoroethane can also be used to produce other chemicals, such as fluorinated pesticides and pharmaceutical intermediates. However, water reacts with dichlorofluoroethane through hydrolysis, producing acidic substances that corrode equipment and pipelines. To improve the production efficiency of dichlorofluoroethane, a phase separation device is needed. However, existing phase separation devices still have the following shortcomings:
[0003] When existing phase separation devices are used, most of them lack a filtration structure before removing water from the dichlorofluoroethane mixture. In addition to water, the dichlorofluoroethane mixture usually contains solid impurities such as rust and mechanical impurities introduced during production or storage. As a result, particulate matter easily accumulates at the drain port at the bottom of the equipment during water removal, causing blockage and preventing the separated water from being discharged smoothly. At the same time, solid particles can wear down components such as ball valves or drain valves, causing them to jam or malfunction. This leads to a decrease in the practicality and efficiency of the phase separation device. Utility Model Content
[0004] The purpose of this invention is to provide a difluorochloroethane aqueous phase separation device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a difluorochloroethane aqueous phase separation device, comprising a main tank and a filter assembly. A mounting frame is installed at the lower end of the main tank, and a receiving base is provided at the bottom of the mounting frame. A filter assembly is provided on the left side of the main tank exterior. The filter assembly includes an inlet valve, a mounting docking block, a limiting mounting groove, a rubber sealing ring, a mounting slide groove, a mounting slider, a threaded mounting block, a mounting sleeve, and a filter cylinder. An mounting docking block is provided at the outer end of the inlet valve, and a limiting mounting groove is formed at the outer end of the mounting docking block. A rubber sealing ring is connected inside the limiting mounting groove. An mounting slide groove is formed inside the mounting docking block, and a mounting slider is connected inside the mounting slide groove. A threaded mounting block is provided outside the mounting slider, and a mounting sleeve is connected outside the threaded mounting block. A filter cylinder is provided at the outer end of the threaded mounting block. A flow guiding assembly is provided inside the main tank.
[0006] Furthermore, the internal dimensions of the limiting mounting groove are adapted to the external dimensions of the rubber sealing ring, and the rubber sealing ring is embeddedly connected to the mounting docking block through the limiting mounting groove.
[0007] Furthermore, the internal dimensions of the mounting groove are adapted to the external dimensions of the mounting slider, and the mounting slider is slidably connected to the mounting docking block through the mounting groove.
[0008] Furthermore, the external dimensions of the threaded mounting block are adapted to the internal dimensions of the mounting sleeve, and the mounting sleeve is rotatably connected to the threaded mounting block.
[0009] Furthermore, the flow guiding assembly includes a receiving frame, an auxiliary baffle, a wave-prevention tilting plate, and an overflow baffle. An auxiliary baffle is installed at the lower end of the receiving frame, and a wave-prevention tilting plate is connected to the middle of the receiving frame. An overflow baffle is provided on the right side of the main tank.
[0010] Furthermore, the flow guiding assembly also includes a liquid guiding strip, a liquid guiding pipe, and a drain pipe, and a liquid guiding strip is installed on the upper end of the overflow baffle, a liquid guiding pipe is provided on the right side of the outside of the main tank, and a drain pipe is provided at the lower right end of the main tank.

[0013] This invention provides a device for separating the aqueous phase of difluorochloroethane, which has the following advantages:
[0014] 1. This utility model, through the setting of the filter component, enables the threaded mounting block and the mounting docking block to be connected and installed in the difluorochloroethane dehydration phase separation device by means of the installation slide groove and the installation slider. The installation is sealed by the rubber sealing ring and the installation docking block and the threaded mounting block are fixed by the installation sleeve, so that the filter cylinder and the liquid inlet valve are fixedly installed.

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0021] like Figure 1 and Figure 2As shown, a dichlorofluoroethane aqueous phase separation device includes a main tank 1 and a filter assembly 4. A mounting bracket 2 is installed at the lower end of the main tank 1, and a receiving base 3 is provided at the bottom of the mounting bracket 2. The filter assembly 4 is located on the left side of the main tank 1. The filter assembly 4 includes an inlet valve 401, a mounting docking block 402, a limiting mounting groove 403, a rubber sealing ring 404, a mounting slide 405, a mounting slider 406, a threaded mounting block 407, a mounting sleeve 408, and a filter cylinder 409. The inlet valve 401 has an mounting docking block 402 at its outer end, and a limiting mounting groove 403 is formed at the outer end of the mounting docking block 402, limiting the mounting... A rubber sealing ring 404 is connected inside the groove 403. An installation slide groove 405 is provided inside the mounting block 402, and an installation slider 406 is connected inside the installation slide groove 405. A threaded mounting block 407 is provided outside the mounting slider 406, and an installation sleeve 408 is connected outside the threaded mounting block 407. A filter cartridge 409 is provided at the outer end of the threaded mounting block 407. The internal dimensions of the limiting mounting groove 403 are adapted to the external dimensions of the rubber sealing ring 404, and the rubber sealing ring 404 is embeddedly connected to the mounting block 402 through the limiting mounting groove 403. The internal dimensions of the installation slide groove 405 are adapted to the external dimensions of the mounting slider 406. The dimensions are compatible, and the mounting slider 406 is slidably connected to the mounting mating block 402 via the mounting groove 405. The external dimensions of the threaded mounting block 407 are compatible with the internal dimensions of the mounting sleeve 408, and the mounting sleeve 408 is rotatably connected to the threaded mounting block 407. The rubber sealing ring 404 is installed into the mounting mating block 402 via the limiting mounting groove 403 at the front end of the mounting mating block 402. The internal dimensions of the mounting groove 405 inside the mounting mating block 402 are compatible with the external dimensions of the mounting slider 406 on the outside of the threaded mounting block 407, thus the mounting groove 405 cooperates with the mounting slider 406. The threaded mounting block 407 is connected to the mounting docking block 402, and the installation is sealed by the rubber sealing ring 404. The mounting sleeve 408 is rotated and installed on the outside of the threaded mounting block 407. At the same time, after the mounting docking block 402 is connected to the threaded mounting block 407, the mounting sleeve 408 is screwed on. The mounting docking block 402 and the threaded mounting block 407 are fixed by the mounting sleeve 408, so that the filter cartridge 409 and the liquid inlet valve 401 are fixedly installed. The difluorochloroethane mixture is filtered by the filter cartridge 409 to prevent impurities from entering the main tank 1, thereby improving the overall practicality and efficiency of the phase separation device.
[0022] like Figure 1 and Figure 3As shown, a flow guiding assembly 5 is installed inside the main tank 1. The flow guiding assembly 5 includes a receiving frame 501, an auxiliary baffle 502, a wave-damping tilting plate 503, and an overflow baffle 504. The auxiliary baffle 502 is installed at the lower end of the receiving frame 501, and the wave-damping tilting plate 503 is connected to the middle of the receiving frame 501. An overflow baffle 504 is installed on the right side of the main tank 1. The flow guiding assembly 5 also includes a liquid guiding strip 505, a liquid guiding pipe 506, and a drain pipe 507. The overflow baffle 504 is located on... A liquid guide strip 505 is installed at one end, a liquid guide pipe 506 is provided on the right side of the main tank body 1, and a drain pipe 507 is provided at the lower right end of the main tank body 1. The external dimensions of the receiving frame 501 are adapted to the internal dimensions of the main tank body 1, and the receiving frame 501 is fixedly connected to the main tank body 1 by bolts. The anti-surge tilting plate 503 is embedded in the receiving frame 501, and the anti-surge tilting plate 503 is rotatably connected to the receiving frame 501 through a rotating shaft. The receiving frame 501 is fixedly installed on the main tank body 1 by fastening bolts. Inside the main tank 1, on the left side, an auxiliary baffle 502 is fixedly installed at the lower end of the receiving frame 501 with fastening bolts. The auxiliary baffle 502 blocks the dichlorofluoroethane mixture when it enters the bottom of the main tank 1. At the same time, it works with the anti-wave tilting plate 503 to prevent the subsequent addition of dichlorofluoroethane mixture from causing excessive fluctuations in the liquid inside the main tank 1, thus reducing the impact on separation. After the dichlorofluoroethane mixture enters the main tank 1, since dichlorofluoroethane is less dense than water, it separates from the water on its own and is above the water. The mixture is blocked by the overflow baffle 504. When the dichlorofluoroethane liquid is higher than the overflow baffle 504, it flows into the right side of the main tank 1 with the help of the liquid guide strip 505. The dichlorofluoroethane is then sent out by the liquid guide pipe 506. After the dichlorofluoroethane separation is completed, the wastewater inside the main tank 1 is discharged through the drain pipe 507, improving the overall practicality and efficiency of the phase separation device.
[0023] In summary, the dichlorofluoroethane aqueous phase separation device, during use, firstly, fixes the mounting bracket 2 to both sides of the upper end of the receiving base 3 with fastening bolts, and then fixes the main tank 1 to the upper end of the mounting bracket 2 with the fastening bolts. The mounting bracket 2 increases the stability of the main tank 1 during use. The opening of the inlet valve 401 allows the external dichlorofluoroethane mixture to enter the main tank 1. The threaded mounting block 407 and the mounting docking block 402 are connected and installed using the mounting groove 405 and the mounting slider 406, and the installation is sealed using the rubber sealing ring 404. The mounting sleeve 408 is rotated and installed outside the threaded mounting block 407, and the mounting docking block 402 and the threaded mounting block 407 are fixed using the mounting sleeve 408. This fixes the filter cartridge 409 and the inlet valve 401, and the dichlorofluoroethane mixture is filtered through the filter cartridge 409. To prevent impurities from entering the main tank 1, an auxiliary baffle 502 blocks the dichlorofluoroethane mixture from entering the bottom of the main tank 1. Simultaneously, a wave-prevention tilting baffle 503 prevents excessive fluctuations in the liquid inside the main tank 1 caused by subsequent additions of the dichlorofluoroethane mixture, reducing the impact on separation. After the dichlorofluoroethane mixture enters the main tank 1, because dichlorofluoroethane is less dense than water, it separates from the water and rises above it. An overflow baffle 504 blocks the mixture, and when the dichlorofluoroethane liquid is higher than the overflow baffle 504, it flows into the right side of the main tank 1 via a guide strip 505. The dichlorofluoroethane is then discharged through a guide pipe 506. After the dichlorofluoroethane separation is complete, wastewater from the main tank 1 is discharged through a drain pipe 507, improving the overall practicality and efficiency of the phase separation device.
