Description

Technical Field

[0001] The utility model relates to the technical field of cleaning devices, in particular to a carbon dioxide cleaning device. Background Art

[0002] The traditional ways of cleaning objects are mainly the following: physical cleaning (manual wiping or equipment cleaning, low-pressure or high-pressure water cleaning), chemical cleaning (acid cleaning, alkali cleaning or organic solvent cleaning). Due to the strong adhesion of stains, manual wiping or equipment cleaning has the disadvantages of incomplete cleaning, low efficiency and instability. Water cleaning or chemical cleaning has the disadvantages of generating a large amount of waste water and waste liquid, using chemicals and high energy consumption. Cleaning is more troublesome and increases people's burden. Carbon dioxide can be used for cleaning. The stored carbon dioxide is passed through a series of devices to spray out a liquid-gas mixture. Carbon dioxide is sprayed onto the dirt on the surface of the object, and the solid tiny particles of dry ice penetrate into the gaps of the dirt. The temperature of the dry ice particles is extremely low, which can freeze the dirt and cause micro-explosion in the gaps of the dirt, expanding the volume by hundreds of times, causing the dirt to crack and peel off. Compared with traditional cleaning, this method can more effectively clean the dirt on the surface of the object and save water resources. However, the existing carbon dioxide cleaning device mainly uses a single-head spray gun to clean the object manually, and the cleaning speed is slow. In addition, the liquid carbon dioxide after cleaning is directly discharged with the oil, resulting in a waste of carbon dioxide, which is not conducive to environmental protection.

[0003] Therefore, it is particularly important to design a carbon dioxide cleaning device that has a fast cleaning speed and reduces the waste of carbon dioxide. Utility Model Content
