Embodiment Construction

[0060] Such as figure 1 Shown, the present invention provides a kind of degreasing oil recovery device, it comprises:

[0061] Degreasing equipment 1, used to degrease the heat exchanger;

[0062] The primary pre-cooling device 2 is in communication with the degreasing equipment 1 so that the oil and gas in the degreasing equipment 1 can be introduced into the primary pre-cooling device 2, and the primary pre-cooling device has a closed first internal cavity , and can reduce the temperature in the first internal cavity to separate oil and gas;

[0063] Air extraction system 3, capable of communicating with the primary pre-cooling device 2, so as to perform suction on the primary pre-cooling device 2, so as to reduce the pressure in the first internal cavity of the primary pre-cooling device 2 .

[0064] In the present invention, by setting the primary pre-cooling device connected to the degreasing equipment and the air pumping system capable of communicating with and pumpin...

Abstract

The invention provides a degreased oil recovery device and a control method. The degreased oil recovery device comprises degreasing equipment (1) for degreasing a heat exchanger, a primary precoolingdevice (2), and a gas extraction system (3), wherein the primary precooling device (2) is communicated with the degreasing equipment (1), can import oil gas into the primary precooling device (2) fromthe degreasing equipment (1), and is provided with an enclosed first internal cavity; a temperature in the first internal cavity can be reduced for oil gas separation; and the gas extraction system (3) can be communicated with the primary precooling device (2) to exert a gas extraction effect on the primary precooling device (2) to reduce pressure in the first internal cavity of the primary precooling device (2). According to the device, the oil gas can be cooled, so that the low boiling point gas is effectively separated; oil separation and recovery effects of the oil gas generated in the degreasing equipment are achieved; the waste of lubricating oil due to direct discharge of the oil is avoided; environmental pollution is reduced; and physical health of staff is ensured.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a degreasing oil recovery device and a control method. Background technique [0002] The heat exchanger is the key core heat exchange component of the air conditioner. The degreasing process of the heat exchanger is to remove the lubricating and cooling grease required for the previous processing. It is an important process that affects the quality of the air conditioner. The heat exchanger contains a large amount of copper tube oil and fin oil. During the degreasing process of the heat exchanger, a large amount of oil mist and exhaust gas (mainly containing triphenyl, styrene, total VOCs, non-methane total hydrocarbons, Nitrogen dioxide, nitrogen oxides, carbon monoxide, smoke blackness, particulate matter, etc.). At present, it is mainly necessary to equip another set of environmental protection equipment for waste gas treatment, which is used to treat the...
