Background
Refrigeration equipment such as refrigerators and air conditioners generally need to use a refrigerant in the use process. These products are produced by first adding a quantity of compressor oil to the compressor and then mixing the refrigerant with the compressor oil after charging the product. If the product needs to be maintained, the product is generally directly discharged, and the method directly discharged is not only wasteful but also environmentally friendly; however, recycling can present a problem: because the refrigerant is mixed with the compressor oil, the recovered refrigerant can not be directly used, and the oil separation treatment needs to be carried out on the mixed liquid, so that the recovered refrigerant can reach the standard of direct use. In view of this, the present invention is directed to a device capable of recycling refrigerant.

Detailed Description
Example 1
As shown in fig. 1, the rectifying device for separating refrigerant oil of the present embodiment includes a rectifying tank 1, and an oil storage tank 2 is hermetically sleeved outside the rectifying tank 1; the rectifying tank 1 is provided with a liquid level sensor 3; the oil storage tank 2 is provided with a liquid level meter 4; a snake-shaped stainless steel coil pipe 5 is arranged in the rectifying tank 1; the top of the rectifying tank 1 is provided with a first outlet 6 and a second outlet 7; the first outlet 6 is connected with an inlet of the snake-shaped stainless steel coil 5 through a pipeline, and a manual valve 11 and a compressor 8 are installed on the pipeline; the outlet of the snakelike stainless steel coil 5 is connected with a liquefaction condenser 13 through a pipeline; the second outlet 7 is connected with a safety valve 9 through a pipeline, and a pressure sensor 10 and a manual valve 11 are arranged on the pipeline; a refrigerant inlet 12 is formed in the bottom of the side face of the rectifying tank, and a pipeline with a manual valve 11 is installed on the refrigerant inlet 12; a third outlet 14 is formed at the bottom of the rectifying tank, and a pipeline with a manual valve 11 is mounted on the third outlet 14; an oil inlet 16 and an air outlet 17 are formed in the top of the oil storage tank 2; the oil inlet 16 and the air outlet 17 are respectively provided with a pipeline with a manual valve 11; an oil outlet 18 is formed in the bottom of the oil storage tank 2, and a pipeline with a manual valve 11 is mounted on the oil outlet 18; the bottom in the oil storage tank 2 is also provided with a heating rod 15.
The method comprises the following steps of firstly starting a compressor 8 before refrigerant and compressor oil mixed liquid recovered by a recovery machine enters a rectifying device to enable a rectifying tank 1 to gradually generate negative pressure, improving recovery efficiency, generating gaseous attraction force to enable the refrigerant and compressor oil mixed liquid to rapidly enter the rectifying tank 1 through a refrigerant inlet 12, enabling liquid level to rise, enabling the refrigerant and compressor oil mixed liquid with relatively cold temperature in the rectifying tank 1 to enter an oil storage tank 2 heated by 2 heating rods 15 to exchange heat; the refrigerant is heated and gasified in the rectifying tank 1, enters the snake-shaped stainless steel coil 5 through the first outlet 6, is liquefied through the liquefaction condenser 13 and is recovered; the refrigerant passing through the serpentine stainless steel coil 5 can be cooled by using a mixed liquid of the cooler refrigerant and the compressor oil in the rectifying tank 1 until the refrigerant flows out of the rectifying tank 1 to the liquefaction condenser 13; the liquid level sensor 3 is used for detecting the liquid level of the adding amount of the mixed liquid of the refrigerant and the compressor oil in the rectifying tank 1; the rectifying tank 1 of the embodiment may further be provided with a temperature probe, and the temperature probe is used to determine whether there is refrigerant in the rectifying tank 1 when the temperature and the pressure detected by the pressure sensor 10 are satisfied, and as an oil discharge condition, when only compressor oil is left after the mixed liquid of the refrigerant and the compressor oil in the rectifying tank 1 is gasified, the third outlet 14 is opened to discharge oil; certainly, when the liquid refrigerant with higher concentration is recovered, the liquid refrigerant can be directly recovered from the third outlet 14 without a rectification link, so that the recovery efficiency is improved.
The rectifying device of this embodiment is simple to use, utilizes the mixed liquid of retrieving machine recovery to get into directly can separating refrigerant and compressor oil behind the rectification jar, has safe high-efficient, and recovery rate is fast, and the refrigerant after retrieving can directly use.
