Abstract

The invention discloses a cleaning and drying method and device through steam and superheated water. No chemical cleaning solvent is used, and workpieces are cleaned through super-strong dirt removing capacity of the steam and the superheated water, so that safety and no toxicity are achieved, and the cleaning speed is high; differential-pressure jet and differential-pressure liquid drainage are used, power required by cleaning and liquid drainage is provided, energy consumption and the device failure rate are reduced, and the cleaning duration is shortened; centrifuge dripping and vacuum drying technologies are combined, and recycling of heat is achieved; gas exhausted by a vacuum pump preheats a water supplement pipe, and heat and moisture in the gas are recovered. Oil and water can be separated easily, cleaning water can be recycled, and the loss of water is quite low during cleaning. Heat and substances in a cleaning system are recycled, the cleaning process is performed in the sealed system, and accordingly secondary pollution is avoided.

Description

technical field [0001] The invention relates to the field of workpiece cleaning, in particular to a steam and superheated water cleaning and drying method and equipment. Background technique [0002] At present, in the cleaning industry, organic solvents or water-based cleaning agents are mostly used to clean the oil and particle impurities on the workpiece. Although these two commonly used cleaning agents have good decontamination effects, they have serious shortcomings. [0003] Although organic solvents have good decontamination effects, strong cleaning ability, and can be recycled, they are harmful to the human body and the environment, and there are certain safety hazards. For example, flammable non-ODS hydrocarbon cleaning agents are non-toxic and easy to dry, but flash Low point, flammable and explosive; non-flammable non-ODS cleaning agent halogenated hydrocarbons, non-flammable, fast volatilization, but very poisonous to the human body. Although water-based cleani...
