Description

Technical Field

[0001] The invention relates to an R123 refrigerant purification device and a use method thereof. Background Art

[0002] R123 refrigerant (also known as trifluoroethylene dichloroethane) is a Freon refrigerant widely used in various refrigeration equipment, including refrigerators, air conditioners, and more. However, R123 refrigerant easily decomposes into chloride ions in the air, causing damage to the ozone layer. Ozone layer depletion can negatively impact the Earth's ecological environment, such as increased ultraviolet radiation and decreased biodiversity.

[0003] Therefore, when such refrigeration equipment is no longer in use, the R123 refrigerant needs to be recycled and reused to reduce environmental pollution, conserve resources, and lower maintenance costs. However, recycled R123 refrigerant often contains a large amount of impurities, such as refrigeration oil and metal powder, and needs to be purified before it can be reused. Summary of the Invention

[0004] The main purpose of the present invention is to provide an R123 refrigerant purification device and a method of using the same to solve the problems raised in the above background.

[0005] The purpose of the present invention can be achieved by adopting the following technical solutions:

[0006] An R123 refrigerant purification device comprises a separation barrel, a liquid inlet pipe and a steam outlet pipe are arranged above the separation barrel at intervals, a heating pipe is arranged inside the separation barrel, and a cooling device is connected to the steam outlet pipe;

[0007] The heating pipe heats the R123 refrigerant to be purified in the separation barrel, causing the R123 therein to be vaporized and escape from the steam outlet pipe to the cooling device, and the cooling device cools the high-temperature gaseous R123 into pure R123 liquid;

[0008] A vibrator is provided at the center of the bottom of the separation barrel, and a plurality of springs are provided around the bottom of the separation barrel, and the bottoms of the springs and the vibrator are both connected to the base;

[0009] The vibrator vibrates to remove R123 bubbles attached to the heating tube and accelerates the escape of gaseous R123.

[0010] Preferably, the cooling device includes an evaporator, the evaporator is connected to a compressor, the compressor is connected to a condenser, the condenser is back-connected to the evaporator, and the steam outlet pipe is connected to the evaporator.

[0011] Preferably, a liquid outlet pipe is provided on the evaporator, and an expansion valve is provided between the condenser and the evaporator.

[0012] Preferably, the heating pipe is arranged at the inner bottom of the separation barrel.

[0013] Preferably, the two ends of the spring are respectively sleeved with an upper sleeve and a lower sleeve, the top of the upper sleeve is connected to the separation barrel, the bottom of the lower sleeve is connected to the base, the upper sleeve is sleeved on the outside of the lower sleeve, and the separation barrel is vibrated by the vibrator, so that the upper sleeve compresses the spring and slides up and down on the outside of the lower sleeve.

[0014] Preferably, six springs are provided, and the six springs are evenly distributed between the separation barrel and the base and along the circumference of the base.

[0015] Preferably, an exhaust pipe is provided above the separation barrel, and an exhaust valve is provided on the exhaust pipe.

[0016] Preferably, a liquid level tube is provided on the side of the separation barrel, and a temperature measuring hole is provided below the liquid level tube.

[0017] Preferably, a sewage pipe is provided at the lower side of the separation barrel, and a sewage valve is provided on the sewage pipe.

[0018] Preferably, a steam outlet valve is provided on the steam outlet pipe.

[0019] A method for using an R123 refrigerant purification device comprises the following steps:

[0020] In the initial state, all valves are closed;

[0021] Step 1: Open the exhaust valve and add the R123 refrigerant to be purified into the separation barrel through the liquid inlet pipe. During the addition process, observe the liquid level through the liquid level tube. Stop adding when it reaches the appropriate liquid level, close the exhaust valve, and open the steam outlet valve and expansion valve;

[0022] Step 2: The heating tube starts heating, insert the temperature probe into the temperature measuring hole to adjust the appropriate heating temperature. After the temperature adjustment is completed, turn on the vibrator;

[0023] Step 3: Under the action of the heating tube, R123 is heated and vaporized. At this time, the pressure in the separation barrel is greater than the pressure in the evaporator, causing most of the gaseous R123 to escape from the steam outlet pipe into the evaporator. A small part of the gaseous R123 forms bubbles and adheres to the heating tube. After being vibrated by the vibrator, this part of the gaseous R123 will break away from the surface of the heating tube and enter the evaporator. At the same time, the vibration accelerates the escape speed of all the gaseous R123.

[0024] Step 4: After the gaseous R123 enters the evaporator, the compressor and condenser start working, forming a refrigeration cycle with the evaporator, so that the gaseous R123 is cooled in the evaporator into pure liquid R123, which flows out from the liquid outlet pipe and is collected;

[0025] Step 5: After the purification is completed, close the steam outlet valve and the expansion valve, open the drain valve, and discharge the impurities remaining in the separation barrel through the drain pipe. After the drainage is completed, close the drain valve.

[0026] Compared with the prior art, the beneficial technical effects of the present invention are:

[0027] 1. Based on the characteristics of R123 refrigerant having a very low boiling point, being easily vaporized when heated and easily condensed when cooled, the present invention heats the R123 refrigerant containing impurities through a separation barrel with a heating pipe inside, so that the R123 therein is vaporized and escapes into the evaporator, thereby achieving separation of R123 from other impurities; by vibrating the separation barrel with a vibrator, R123 bubbles attached to the heating pipe during the vaporization process are vibrated off, so that this part of the gaseous R123 also enters the evaporator, thereby ensuring the heating efficiency of the heating pipe and improving the purification rate of R123. By purifying and recycling the R123 refrigerant, the demand for new refrigerant is reduced, thereby reducing pollution to the environment.

[0028] 2. The present invention heats the R123 refrigerant in the separation barrel via a heating tube, creating a large amount of hot R123 gas inside the separation barrel. This creates a pressure differential between the separation barrel and the evaporator, creating a natural mass transfer driving force. This allows the gaseous R123 to move naturally from the separation barrel to the evaporator without relying on additional conveying devices. This simplifies equipment operation, reduces the use of additional equipment and energy consumption, and makes the entire purification process more environmentally friendly.

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] See also Figures 1 to 7 The present invention provides an embodiment of an R123 refrigerant purification device, comprising a separation barrel 1, a liquid inlet pipe 2 and a steam outlet pipe 3 are spaced apart above the separation barrel 1, a heating pipe 4 is provided inside the separation barrel 1, and a cooling device 5 is connected to the steam outlet pipe 3;

[0039] The heating tube 4 heats the R123 refrigerant to be purified in the separation barrel 1, gasifying the R123 therein and escaping from the steam outlet pipe 3 to the cooling device 5. The cooling device 5 cools the high-temperature gaseous R123 into pure R123 liquid, which can effectively recover and purify the R123 refrigerant, avoiding the pollution of the R123 refrigerant to the environment. The heating tube 4 is set at;

[0040] A vibrator 6 is provided at the bottom center of the separation barrel 1, and a plurality of springs 7 are provided around the bottom of the separation barrel 1. The bottoms of the springs 7 and the vibrator 6 are both connected to a base 8.

[0041] The vibrator 6 vibrates to remove R123 bubbles attached to the heating tube 4 during the heating process and accelerates the escape of gaseous R123. When the heating tube 4 is heated, the vibrator 6 is started at the same time, so that the R123 refrigerant in the separation barrel 1 undergoes heating and vibration at the same time. Once R123 bubbles appear on the heating tube 4, they will quickly break away from the heating tube 4 under the action of the vibrator 6, and then enter the cooling device 5 from the steam outlet pipe 3. The combined action of the vibrator 6 and the heating tube 4 greatly improves the purification efficiency of the purification device.

[0042] Furthermore, the cooling device 5 includes an evaporator 501, the evaporator 501 is connected to a compressor 502, the compressor 502 is connected to a condenser 503, the condenser 503 is back-connected to the evaporator 501, and the steam outlet pipe 3 is connected to the evaporator 501. The evaporator 501, the compressor 502 and the condenser 503 constitute a refrigeration cycle, which cools the gaseous R123 entering the evaporator 501 into liquid.

[0043] Furthermore, a liquid outlet pipe 9 is provided on the evaporator 501, so that the R123 cooled into liquid flows out of the evaporator 501, is collected and reused, and an expansion valve 504 is provided between the condenser 503 and the evaporator 501 for controlling the refrigerant flow between the condenser 503 and the evaporator 501.

[0044] Furthermore, the heating tube 4 is arranged at the inner bottom of the separation barrel 1 and has a lower center of gravity, so that the heating tube 4 can maintain a stable state when the vibrator 6 vibrates.

[0045] Furthermore, the two ends of the spring 7 are respectively sleeved with an upper sleeve 10 and a lower sleeve 11. The top of the upper sleeve 10 is connected to the separation barrel 1, and the bottom of the lower sleeve 11 is connected to the base 8. The upper sleeve 10 is sleeved on the outside of the lower sleeve 11. The separation barrel 1 is vibrated by the vibrator 6, so that the upper sleeve 10 compresses the spring 7 and slides up and down on the outside of the lower sleeve 11. There are six springs 7, and the six springs 7 are between the separation barrel 1 and the base 8 and are evenly distributed along the circumference of the base 8, which can stably support the separation barrel 1. Even when the vibrator 6 is working, the stability of the separation barrel 1 can be guaranteed to avoid damage to the device or decreased working efficiency due to excessive vibration. The design of the upper sleeve 10 and the lower sleeve 11 makes the spring 7 more evenly stressed, reduces the wear of the spring 7, and thus extends the service life of the spring 7 and the entire device.

[0046] Furthermore, an exhaust pipe 12 is provided above the separation barrel 1, and an exhaust valve 13 is provided on the exhaust pipe 12. When the R123 refrigerant to be purified is added, the exhaust valve 13 is opened to connect the separation barrel 1 with the outside world, so that the internal and external pressures are consistent, thereby preventing damage to the separation barrel 1 and improving the liquid injection efficiency.

[0047] Furthermore, a liquid level tube 14 is provided on the side of the separation barrel 1, and a temperature measuring hole 15 is provided below the liquid level tube 14 for monitoring the liquid level and temperature of the R123 refrigerant in the separation barrel 1 to ensure smooth purification process.

[0048] Furthermore, a drain pipe 16 is provided at the lower side of the separation barrel 1 , and a drain valve 17 is provided on the drain pipe 16 for discharging impurities such as refrigeration oil, metal debris, etc. remaining after the R123 is gasified and separated.

[0049] Furthermore, a steam outlet valve 18 is provided on the steam outlet pipe 3 for controlling the gas flow of the steam outlet pipe 3 .

[0050] A method for using an R123 refrigerant purification device comprises the following steps:

[0051] In the initial state, all valves are closed;

[0052] Step 1: Open the exhaust valve 13 and add the R123 refrigerant to be purified into the separation barrel 1 through the liquid inlet pipe 2. During the addition process, observe the liquid level through the liquid level tube 14. When the liquid level reaches the appropriate level, stop adding, close the exhaust valve 13, and open the steam outlet valve 18 and the expansion valve 504.

[0053] Step 2: The heating tube 4 starts heating, and a temperature probe is inserted into the temperature measuring hole 15 to adjust the appropriate heating temperature. After the temperature adjustment is completed, the vibrator 6 is turned on;

[0054] Step 3: Under the action of the heating tube 4, the R123 is heated and vaporized. At this time, the pressure in the separation barrel 1 is greater than the pressure in the evaporator 501, causing most of the gaseous R123 to escape from the steam outlet pipe 3 into the evaporator 501. A small part of the gaseous R123 forms bubbles and adheres to the heating tube 4. After being vibrated by the vibrator 6, this part of the gaseous R123 will break away from the surface of the heating tube 4 and enter the evaporator 501. At the same time, the vibration accelerates the escape speed of all the gaseous R123.

[0055] Step 4: After the gaseous R123 enters the evaporator 501, the compressor 502 and the condenser 503 start working, forming a refrigeration cycle with the evaporator 501, so that the gaseous R123 is cooled in the evaporator 501 into pure liquid R123, which flows out from the liquid outlet pipe 9 and is collected;

[0056] Step 5: After the purification is completed, close the steam outlet valve 18 and the expansion valve 504, open the drain valve 17, and discharge the impurities remaining in the separation barrel 1 through the drain pipe 16. After the drainage is completed, close the drain valve 17.
