Refrigerator purification treatment is an important technology, which involves multiple links such as refrigerant recovery, purification, and reuse. The following is the general technical process of refrigerant purification treatment:
1. Refrigerant recovery
Refrigerant recovery is the first step in refrigerant purification treatment. After the refrigeration equipment stops running, special recovery equipment is needed to extract and collect the refrigerant from the system. This process needs to ensure that the refrigerant does not leak into the environment, and it is also necessary to prevent air and other pollutants from entering the refrigerant. The recovered refrigerant is usually stored in a special container waiting for subsequent purification treatment.
2. Refrigerant purification
After the refrigerant is recovered, it needs to be purified to remove impurities and pollutants. The purification process usually includes the following steps:
a. Filtration
Filtration is the basic step to remove solid impurities in refrigerant. By using filters with different pore sizes, solid particles such as metal fragments and dust in the refrigerant can be effectively removed.
b. Adsorption
Adsorption is mainly used to remove moisture and other volatile organic compounds from refrigerants. Commonly used adsorption materials include activated carbon, molecular sieves, etc. These materials have a large specific surface area and can effectively adsorb moisture and impurities in the refrigerant.
c. Distillation
Distillation is a method of heating the refrigerant to vaporize it and then condense it for separation. This method can effectively separate the different components in the refrigerant and remove impurities and pollutants.
3. Refrigerant reuse
If the quality of the purified refrigerant meets the relevant standards, it can be recharged into the refrigeration equipment for use. Before charging, the refrigeration equipment needs to be fully inspected and maintained to ensure that the equipment is in good sealing and operating condition. In addition, the quality of the refrigerant needs to be retested to ensure that it meets the requirements for use.
4. Safety operating procedures
During the recovery, purification and reuse of refrigerants, safety operating procedures must be strictly followed to ensure the personal safety of operators and the safety of equipment. This includes wearing personal protective equipment, regularly checking the status of the equipment, and properly disposing of waste.
The above is the general technical process of refrigerant purification. It should be noted that the specific purification method may vary depending on different types of refrigerants and different application scenarios. In actual operation, appropriate purification treatment technology and methods should be selected according to specific circumstances.
