Abstract

The invention discloses a viscose production waste gas adsorptive recovery system, which comprises an alkaline washing fan, an alkaline washing tank, a Na2S and NaHS storage tank, a washing tower, a fan, an active carbon adsorption tank, an evaporator, a condenser, a gas-liquid separator, a gravity separator, an after-cooler and a CS2 storage tank, wherein the alkaline washing tank is connected with the alkaline washing fan; the Na2S and NaHS storage tank and the washing tower are connected with the alkaline washing tank; the fan is connected with the washing tower; the active carbon adsorption tank is connected with the fan; the evaporator is connected with the active carbon adsorption tank; the condenser is connected with the evaporator; the gas-liquid separator is connected with the condenser; the gravity separator is connected with the gas-liquid separator; the after-cooler is connected with the gravity separator; and the CS2 storage tank is connected with the after-cooler. The viscose production waste gas adsorptive recovery system has the advantages of capabilities of effectively collecting waste gas containing H2S and CS2 to reach the national emission standard and preventing atmospheric and environmental pollution, good collection effect and lower cost input.

Description

technical field [0001] The invention relates to an industrial waste gas treatment device, in particular to an adsorption recovery system for viscose production waste gas. 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 stati...
