Description
Technical Field
[0001] The utility model relates to a salt spray treatment device used in an artificial simulated salt spray environment, in particular to the structure of the salt spray treatment device. Background Art
[0002] Salt spray test is an environmental test that mainly uses the artificial simulated salt spray environment conditions created by the salt spray test chamber to test the corrosion resistance of products or metal materials. Salt spray test generally uses a salt spray test chamber. During the test, a large amount of salt spray will be generated in the salt spray test chamber. After the test is completed, the salt spray is discharged from the exhaust port of the salt spray test chamber.
[0003] Salt spray is a dispersion system composed of tiny salt droplets (hereinafter referred to as salt solution) in the gas. It is highly corrosive and can cause great damage to surrounding equipment and facilities. For example, salt spray corrosion can destroy the metal protective layer and reduce mechanical strength; it can corrode electronic components and electrical circuits, causing power line interruption; salt spray falls on the surface of the insulator, and after the insulator absorbs the salt solution, its volume resistance will be reduced by four orders of magnitude; the active parts of mechanical parts or moving parts increase friction due to the generation of corrosive products, causing the moving parts to be stuck.
[0004] In order to prevent salt spray vapor from corroding indoor items, the existing method usually connects an exhaust pipe to the exhaust port of the salt spray test box, and guides the salt spray to the outside through the exhaust pipe for natural discharge. Although this method reduces the corrosion of salt spray vapor to indoor items, it will cause corrosion and damage to outdoor equipment and facilities, walls, vegetation and other items, seriously affecting the environment.
[0005] In addition, during the salt spray test operation and salt spray discharge process, a small amount of salt spray will leak, which will also cause corrosion and damage to surrounding equipment.

The finally treated gas is discharged from the exhaust port 12, and the neutralizing liquid mixed and reacted with the salt liquid in the salt mist is discharged from the discharge port 13 at regular intervals. When the pH meter 45 detects the occurrence of salt mist leakage, the leaked salt mist is collected by the fume hood 42 and drawn into the processing chamber 11 by the induced draft fan 43 for processing.
