Description

TECHNICAL FIELD

[0002] With the rise of new energy technology, etching equipment is emerging more and more, and many chemicals are needed in the production process. And the chemicals used for etching are dangerous goods, which are highly corrosive and toxic. If leakage occurs, it will cause safety accidents. Therefore, a good exhaust system must be provided in the production process. Strong base NaOH is used in etching. Under normal circumstances, it will not burn, but NaOH and related reaction products form salt crystals in the exhaust duct through exhaust. The crystals cause the exhaust to be not smooth, and the duct is easy to condense H2 flammable substances and O2 combustion-supporting gas. Because there are mixtures such as NAOH and Na2SiO3 in the exhaust duct, the crystals and liquid droplets in the suspended air will generate and accumulate static electricity during the flow process, and as the temperature in the duct increases, the static electricity ignites the explosive mixture when it reaches a certain value.

[0003] The prior art generally uses manual opening of the exhaust duct for cleaning. Because the crystals contain strong alkali, the diluted solution is highly corrosive and can cause irreversible harm to the human body. Therefore, manual cleaning has the disadvantages of incomplete inspection, incomplete cleaning, low efficiency and high risk. There are also some automatic cleaning devices, but the significant disadvantages are poor controllability, more residues and incomplete cleaning. SUMMARY
