Problems solved by technology

[0004] It can be seen from the above that the waste gas discharged from the viscose fiber manufacturing process contains high concentrations of carbon disulfide, and in the viscose production process, due to the influence of conventional factory layout, investment and operational safety, there is no suitable waste gas receiving point and disposal method , so that the exhaust gas is directly discharged into the atmosphere, which will not only cause the emission loss of carbon disulfide, but also cause environmental pollution
