Abstract
An alkaline washing tank, washing tower and adsorption tank system comprises a gas inlet and an exhaust outlet. Waste gas generated in viscose fiber production is sucked from the gas inlet of the alkaline washing tank by a fan unit and then is subjected to alkaline washing and spraying uniformly, and residual waste gas is sucked into the washing tower from the gas inlet and is sprayed by the aid of a water washing stage and an alkaline washing stage. The waste gas and liquid medium are in contact reaction, the waste gas contacts with washing liquid flowing on the surface of a filling material sufficiently so that acid or alkaline sewage in the waste gas can be adsorbed. The residual waste gas is sucked into the adsorption tank via the gas inlet arranged at the bottom of the adsorption tank and contacts with activated carbon sufficiently after being adsorbed by activated carbon packing, and after being processed, qualified gas is exhausted to the atmosphere from the exhaust outlet arranged at the top end of the adsorption tank directly. Since the system utilizes high-efficiency air blower, energy efficiency is better. Adsorption effect is fine due to large specific surface area of the filling material. In addition, acid or alkaline waste gas effectively can be treated effectively, and acid and alkaline removal rate can be over 90%.
