Carbon dioxide snowflake cleaning system for substrate spraying pretreatment

Abstract

The invention discloses a carbon dioxide snowflake cleaning system for substrate spraying pretreatment. The system comprises a liquid-state carbon dioxide storage tank with liquid-state carbon dioxideat the lower part and gas-phase carbon dioxide at the upper part; the upper part and the lower part of the liquid-state carbon dioxide storage tank are connected with an inlet of a carbon dioxide filter through a gas-phase carbon dioxide output pipe and a liquid-phase carbon dioxide output pipe with a gas-phase carbon dioxide stop valve and a liquid-phase carbon dioxide stop valve; an outlet of the carbon dioxide filter is connected with an inlet of a supercharger; an outlet of the supercharger is connected with an inlet of a heater; a main pipeline of the supercharger connected with the heater is connected with a voltage stabilizer through a branch pipeline; an outlet of the heater is connected with an inlet of a refrigerator; and an outlet of the refrigerator is connected with an inletof a nozzle connected with a compressed air introduction system by a carbon dioxide electromagnetic valve. The system uses no chemical reagent, is low in energy consumption, generates no waste water and waste liquid, and is excellent and stable in cleaning effect and high in efficiency.

Description

technical field [0001] The invention relates to the technical field of cleaning systems, in particular to a carbon dioxide snowflake cleaning system used for substrate spraying pre-treatment. Background technique [0002] The traditional pre-spray treatment process uses acidic or alkaline chemicals and water as the medium to clean the substrate through chemical reaction and rinsing, including degreasing, washing, drying, drying and cooling processes. The method has the disadvantages of generating waste water and using chemical agents, which is not environmentally friendly; the whole system has the disadvantages of high energy consumption. Contents of the invention [0003] The purpose of the present invention is to aim at the technical defects existing in the prior art, and to provide a carbon dioxide snowflake cleaning system with carbon dioxide snowflake-like crystals as the cleaning material, which is suitable for cleaning substrates of various materials and surface par...
