Description

Circulating spraying system for laser wet cleaning

Technical Field

The utility model relates to a spray set field especially relates to a circulation spraying system for wet washing of laser.

Background

During laser cleaning, due to the combined action of rapid thermal vibration, vaporization, melting, plasma stripping and the like generated by the direct irradiation of high-power-density laser on the surface of a cleaned object, surface pollutants are instantly vaporized, ablated or stripped, and especially pollutants of combustible gas can be generated after high-temperature vaporization. Such as: the colloid on the metal glue pressing valve is as thick as about 4mm, a plurality of pulses are needed for cyclic cleaning and removal, the colloid generates combustible gas and is directly combusted after being radiated by laser with high power density, the colloid and the combustible gas interact, the infrared thermal imager detects that the surface temperature rise exceeds 150 ℃, the melting and recondensing phenomenon occurs on the surface of the base material, and the thermal influence is generated on the surface of the material. The existing laser cleaning method mainly comprises the following steps: a. the laser dry cleaning method adopts pulse laser to directly radiate for decontamination; b. the laser and liquid film method, namely, a layer of liquid film is deposited on the surface of the substrate at first, and then the laser radiation is used for decontamination; c. the laser and inert gas method is characterized in that while laser is radiated, inert gas is blown to the surface of a substrate, and dirt is blown off the surface by the gas immediately after being stripped from the surface, so that the surface is prevented from being polluted and oxidized again; d. the laser + non-corrosive chemical method is to loosen dirt by using laser and then clean the dirt by using the non-corrosive chemical method. Laser dry cleaning methods are generally adopted, and the methods have difficulty in avoiding adverse effects of heating influences such as near-surface hardening and the like on the surface of a material for removing serious pollution which needs to be cleaned in a circulating way by multiple pulses. If the surface of the material is cleaned by adopting high-power-density laser, spraying water on the surface of the cleaned object; or the cleaned object is immersed in water, and the water is adopted to spray the surface of the cleaned object, so that the vaporization of water or other cooling and heat-dissipating liquid is utilized to absorb and dissipate heat of the laser radiation surface, the thermal influence of the laser on the material is eliminated, and the wet cleaning of the laser on the surface of the material is realized. A spray system is required in the process. The current spraying systems on the market do not have the function of recycling water or other cooling and heat dissipating liquids.
