Abstract

The invention relates to a system for industrial waste gas treatment and salt regeneration, which comprises a waste gas treatment device, a neutralization deslagging device, a salt liquid concentration device, a main water supply pipe, an alkali liquid feeding tank and a hydrochloric acid storage tank, wherein the waste gas treatment device is provided with absorption towers No.1-No.5, a gas-liquid separator, a blender, an acid liquid clarifying tank and an alkali liquid transit tank; the neutralization deslagging device is provided with a neutralization mixing kettle, an impurity elimination tank, a filter press and a salt liquid transit tank; and the salt liquid concentration device is provided with a preheater, a heater, an evaporator, a crystallizer, a salt liquid mixing tank, a centrifuge, a condenser and a condensing water tank. The system can effectively treat industrial waste gas containing chlorine gas and hydrogen chloride gas. Since products are reclaimed from waste liquid, the added value of the system is improved, and simultaneously, problems on sewage discharge do not exist.

Description

technical field [0001] The invention relates to an industrial waste gas treatment and salt regeneration system. Background technique [0002] The industrial waste gas containing chlorine gas and hydrogen chloride gas produced in industrial production needs to be treated and discharged only after reaching the standard. The Chinese patent No. 200720005231.7 utility model patent specification discloses an exhaust gas treatment device, which has a first-stage scrubber, a second-stage turbulent tower, and a third-stage turbulent tower. The first-stage scrubber and the second and third-stage turbulent towers are equipped with No. 1, No. 2 and No. 3 heat exchangers. In addition, the system also has a lye main pipe, a water inlet pipe, a cooling water supply main pipe, a cooling return water main pipe, and a discharge main pipe. The exhaust gas is drawn by the fan into the first-stage scrubber, and in the turbulence pipe of the first-stage scrubber, it fully contacts with the water...
