Anti-corrosion acid mist treatment tower

Abstract

The invention discloses an anti-corrosion acid mist treatment tower, and relates to the technical field of environmental protection equipment, the anti-corrosion acid mist treatment tower comprises three acid mist treatment mechanisms, a ventilation pipeline is arranged between every two adjacent acid mist treatment mechanisms, an induced draft fan is arranged in the middle of one ventilation pipeline, and each acid mist treatment mechanism comprises a tower body; a partition plate, a collecting plate and a spraying assembly are arranged in the tower body, the partition plate and the collecting plate divide the inner space of the tower body into a dosing cavity, a precipitation cavity and an acid pickling cavity, a lower leakage opening is formed in the middle of the collecting plate, a cleaning assembly is inserted into the middle of the tower body, and an insertion opening is formed in the upper end of the tower body. Through continuous work of the multiple acid mist treatment mechanisms, harmful substances in waste gas can be absorbed and removed, energy conservation and environmental protection are achieved, through arrangement of the cleaning assembly, disassembly and assembly can be rapidly achieved, overhaul and maintenance are convenient, the bottom of the filling layer can be cleaned at regular time, the passing efficiency of the waste gas is guaranteed, and the treatment effect of the waste gas is improved.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to an anti-corrosion acid mist treatment tower. Background technique [0002] In the production process of stainless steel, the pickling tank is a commonly used facility. In addition to the generation of a large amount of steam, acid mist and harmful gas when the pickling tank is adding acid, the acid gas in the acid tank also continues to volatilize and has a pungent smell. The main pollutants in the pickling project are hydrofluoric acid and nitric acid mist. Hydrofluoric acid (HF) is an aqueous solution of hydrogen fluoride gas. It is colorless, has a pungent odor, and is highly corrosive. It is obtained by dissolving hydrogen fluoride in water. Concentrated nitric acid mist can release nitrogen pentoxide to form acid mist when it meets water vapor, which can be quickly decomposed into nitrogen dioxide, causing respiratory tract irritation symptoms aft...
