<p>PURPOSE: A recovery system of drug gas is adapted to recycle gas in a more recyclable form by using water before neutralizing the gas in a scrubber by using a neutralizing agent, so that the amount of the neutralizing agent consumed in the gas scrubber can decrease. CONSTITUTION: A recovery system of drug gas includes a reservoir for storing liquid drug, a gas treatment means coupled to the reservoir by a first supply tube for treating the gas in the reservoir supplied by the first supply tube, and a retreatment means boned to the gas treatment means by a second supplying tube for retreating the gas remained unprocessed by the gas treatment means. The gas treatment means comprises a micro spray, a heat exchanger, a demister, a filter section, a collection tank, and a first fan. The retreatment means has a second fan and a wastewater sludge tank. A bypass tube disposed between the reservoir and a micro spray in the first tube and the first and the second fans of the second supply tube is indirectly connected to the gas treatment means. The bypass tube is indirectly connected to the outside of the gas treatment means.</p> |
