Explosion-resisting method and device for electro-galvanizing zinc dissolving station

Abstract

The present invention reveals explosion preventing method and apparatus for electroplated zinc dissolving station. The explosion preventing apparatus connected to the zinc dissolving tank and zinc dissolving pump in electroplated zinc dissolving station includes one zinc grain position detector to send out one warning signal in case of zinc grain position lower than certain set position; and one controller connected to the zinc grain position detector to change the operation rate of the zinc dissolving pump to one safe value when the zinc grain position detector sends out warning signal. The present invention can prevent accident caused by hydrogen overflow actively.

Description

technical field [0001] The invention relates to the safety protection technology of electro-galvanizing equipment, more specifically, relates to an explosion-proof method and device of an electro-galvanizing and dissolving station. Background technique [0002] In the current continuous electrogalvanizing unit using the gravity electroplating process, the supplement of zinc ions in the electroplating process is realized by continuously dissolving zinc particles through the zinc dissolving station system. During the process of dissolving zinc in the zinc dissolving station, a large amount of hydrogen gas will be generated. Although the exhaust gas exhaust device continuously pumps the hydrogen-containing waste gas into the atmosphere for release, the hydrogen gas in the zinc dissolving tank will still maintain a certain pressure. Once the zinc particles are dissolved and are not added in time, hydrogen gas will overflow from the mouth of the zinc feeding pipe. When the concen...
