Problems solved by technology

The above-mentioned waste gas treatment device has treated the industrial waste gas containing chlorine gas and hydrogen chloride gas to make the discharged gas meet the standard. However, if the discharge liquid is not treated, there will still be pollution problems. At present, there is no product that can adapt to computer program control and can recycle products. waste gas treatment system

Abstract

The invention relates to a waste gas treatment system and a computer control method. The waste gas treatment system comprises a waste gas treatment device, a neutralizing device, a salt liquid condensing device and a control device. A spraying and absorbing tower I uses neutral water as an absorbing liquid; an absorbing tower II uses alkali liquor as an absorbing liquid; waste absorbing liquid drained by the spraying and absorbing tower I is acid; waste absorbing liquid drained by the spraying and absorbing tower II is alkali; and two kinds of waste liquids are mixed together to generate salts, thus industrial salt products can be recovered from the waste liquid generated in the waste gas treatment process. The product can be recovered from the waste liquid, thereby improving the added value of the system. By adopting the computer to control, the invention has the advantages of simple operation, accurate control and high automatic program.

Description

technical field [0001] The invention relates to an exhaust gas treatment system and a computer control method thereof. 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 th...
