Hydrogen chloride gas circulation absorption water saving device

Abstract

The utility model provides a kind of hydrogen chloride gas circulation absorption water-saving device, it is related to chemical production technical field, the current mode production vinyl chloride, most is through pipeline conveying hydrogen chloride gas, then again access water pipe on conveying pipeline, so that hydrogen chloride gas and water are mixed in pipeline, then the mixed solution is conveyed to specified position to carry out subsequent reaction operation, but the mixing mode can make hydrogen chloride gas and water mixed unevenly;The utility model is mixed by setting component, reaction solution is conveyed to hydrochloric acid vertical tank by feed pipe and then reacts, then the gas generated is conveyed to water tank and solution by conveying pipe and aeration piece and mixes, after motor drives transmission rod, it is driven mixing blade by transmission rod to speed up mixing efficiency, after the mixed solution is conveyed to circulation absorption tower and works, simultaneously under the joint action of circulation pipe and water pump B, realize the recycling of solution and save part cost.
