Dry ice cleaning device and cleaning method thereof

Abstract

The invention provides a dry ice cleaning device and a cleaning method thereof. The device comprises an air compressed system and an injection system communicated with the air compressed system, wherein the air compressed system comprises an air compressor, a high-pressure gas pipeline and a low-pressure gas pipeline; the high-pressure gas pipeline and the low-pressure gas pipeline are respectively communicated with the air compressor and converge to the injection system through independently moving; a material division mechanism and a reducing valve are arranged on the low-pressure gas pipeline; the high-pressure gas pipeline adopts a venturi spray pipe; the air compressed system is communicated with a nozzle through the venturi spray pipe; and the outlet end of the material division mechanism is communicated with the tail end of the venturi spray pipe in the air compressed system and is connected with the injection system. According to the invention, water resources can be saved, the operating cost is reduced, and simultaneously, no cleaning agent residues exist; the exhaust gas of carbon dioxide is utilized, so that the emission of greenhouse gases is reduced; and the surface of a cleaned object cannot be damaged, and a low-temperature disinfection function is achieved. At the same time, in the invention, the dry ice cleaning device for industrial use is miniaturized so as to be applied to the field of family food sanitation.

Description

technical field [0001] The invention relates to the field of cleaning technology, in particular to a dry ice cleaning device using dry ice as a cleaning medium and a cleaning method thereof. The dry ice cleaning device and cleaning method thereof are particularly suitable for the field of food hygiene. Background technique [0002] Dry ice is solid carbon dioxide, CO 2 It is one of the main application products in social production, but people are concerned about CO 2 applications are very limited. At present, countries around the world are seeking effective methods and measures to reduce the harm to the human living environment, and people are also actively exploring how to use CO 2 The characteristics are applied in industrial and civil ways. [0003] At present, traditional physical and chemical cleaning methods are still mainly used in the cleaning industry in our country. Because traditional physical cleaning methods often damage the surface of the cleaned object, c...
