Refrigerant recovery method capable of effectively avoiding volatilization of thermoelectric refrigerant

Abstract

The invention provides a refrigerant recovery method capable of effectively avoiding volatilization of a thermoelectric refrigerant. The refrigerant recovery method capable of effectively avoiding volatilization of the thermoelectric refrigerant comprises the following steps: S1, extracting and guiding: extracting and guiding a used refrigerant gas-liquid mixture; S2, carrying out filtering and impurity removal: filtering and drying impurities contained in the refrigerant, removing moisture in a gas-phase refrigerant, and enabling the liquid-phase refrigerant to enter a refrigerant recycling bottle; S3, carrying out oil removal: separating and collecting freezing lubricating oil contained in the used refrigerant; S4, cooling and separating: separating the refrigerant in a gas-liquid mixed state; and S5, recycling: recycling the clean refrigerant for reuse. The refrigerant recovery method capable of effectively avoiding the volatilization of the thermoelectric refrigerant provided by the invention has the advantages that the refrigerant can be effectively prevented from being volatilized into air in the refrigerant recovery process, and damage to the environment caused by part of the refrigerant is prevented.

Description

technical field [0001] The invention relates to the technical field of refrigerants, in particular to a refrigerant recovery method which can effectively avoid volatilization of thermoelectric refrigerants. Background technique [0002] Refrigerants, also known as refrigerants and snow species, are medium substances used to complete energy conversion in various heat engines. These substances usually use reversible phase transitions (such as gas-liquid phase transitions) to increase power, such as steam in steam engines. , the refrigerant in the refrigerant, etc., when the general steam engine is working, it releases the heat energy of the steam and converts it into mechanical energy to generate the driving force; the refrigerant of the refrigerant is used to transfer the heat from the low temperature to the high temperature. [0003] At present, in industrial production and life, refrigerants are often used. After the refrigerant is used, the refrigerant needs to be recovere...

AI Technical Summary

Problems solved by technology

[0003] At present, in industrial production and life, refrigerants are often used. After the refrigerant is used, the refrigerant needs to be recovered. However, during the recovery process of the refrigerant, the liquid phase refrigerant will volatilize and leak. At the same time, part of the gas-phase refrigerant is not fully recovered, causing it to leak in the air, causing various damages to the environment
