Abstract

The invention discloses a waste gas recovery system for mucilage production with a good treatment effect. The recovery system comprises an alkali cleaning fan, an alkaline bath connected with the alkali cleaning fan, an Na2S and NaHS storage tank and a water scrubber which are connected with the alkaline bath, a draught fan connected with the water scrubber, an activated carbon adsorption tank connected with the draught fan, an evaporator connected with the activated carbon adsorption tank, a first condenser connected with the evaporator, a gas-liquid separator and a second condenser which are connected with the first condenser, a specific gravity separator and a safety can which are connected with the gas-liquid separator, and an after-cooler connected with the specific gravity separator, and a CS2 storage tank connected with the after-cooler. The second condenser is connected with the gas-liquid separator, and the safety can is connected with the specific gravity separator and the draught fan.

Description

technical field [0001] The invention relates to an industrial waste gas treatment device, in particular to a viscose production waste gas recovery system. Background technique [0002] During the production process of viscose fiber, a large amount of waste gas containing H2S and CS2 will be produced. These waste gases mainly overflow at the following process points, namely: the exhaust of the yellowing machine, the waste gas of the spinning machine, drafting and cutting machine, and the second bath tank after condensation Exhaust gas after condensation from the device, fluff forming exhaust gas, scouring machine-washing exhaust gas, acid station degassing and exhaust gas from each bath. Due to the characteristics of the viscose fiber production process, the composition of the exhaust gas at each overflow point is also different: the exhaust gas H2S and CS2 concentrations from the spinning machine are both high, and the exhaust gas degassed from the acid station has the highe...
