Abstract

The invention discloses a sulfuric acid tail gas treatment device, which comprises an insulating box and a sealing plate, wherein positive plates and negative plates are arranged in the insulating boxin a staggered mode and electrically communicated with a positive electrode and a negative electrode respectively; a plurality of discharging needles are arranged on one side, facing the positive plate, of the negative plate; airflow channels are formed in the end parts of the positive plate and the negative plate; absorbing liquid is conveyed through a spraying pipe and a spraying head which arearranged on the insulating box; a high-voltage electric field is formed by the positive plate and the negative plate to ionize a phase entering the insulation box; meanwhile, the structure that the positive plates and the negative plates are arranged in a staggered mode forms a W-shaped airflow loop in the insulating box body, so that the residence time of airflow in the insulating box is prolonged, the effective action time of an electric field on gas is guaranteed, and the treatment effect is improved. Compared with the prior art, the method has the advantages that no wastewater is generated, the recycled product can be reused, the treatment effect on sulfuric acid industrial tail gas is improved, and the environment-friendly emission pressure is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of sulfuric acid tail gas treatment, in particular to a sulfuric acid tail gas treatment device and a treatment process. Background technique [0002] Electrostatic demister is a gas-liquid separation wet process equipment with the least resistance to purifying fluid. It can be used for acid production from smelting flue gas, titanium dioxide calcination tail gas treatment, various acid mist treatment in chemical plants, and is mostly used in sulfuric acid and other industries. The working principle of the electrostatic demister is: through the electrostatic control device and the DC high-voltage generator, the alternating current is converted into direct current and sent to the demisting device to form The strong electric field ionizes the air molecules, and instantly produces a large number of electrons and positive and negative ions. These electrons and particles move directionally under the action of the...
