The utility model discloses an efficient and stable organic
waste gas purification device which comprises a reactor main body, and the reactor main body is sequentially provided with a circulating
nutrient solution supply area, an inlet and outlet area and a
biodegradation area from bottom to top; a circulating
liquid storage tank is arranged at the bottom of the circulating
nutrient solution supply area, and a first feeding opening, a circulating
nutrient solution discharging opening and a second feeding opening are formed in the upper part of the circulating
liquid storage tank; a
sludge outlet is formed in the bottom of the circulating
liquid storage tank; a thermodetector, a second
pressure monitoring port and an air inlet are arranged on the side wall of the inlet-outlet area; a perforated air distribution
pipe is arranged at the upper part of the air inlet; the
biodegradation area is sequentially provided with a filler layer and a
sprayer from bottom to top, and a material changing opening is formed in the side wall of the filler layer; a gas outlet is formed in the top of the reactor main body, and a first
pressure monitoring port is formed in the side wall between the
demister and the first
sprayer. According to the utility model, the
pressure monitoring system is additionally arranged, so that real-
time pressure monitoring and QQ
enzyme feeding are realized, manual regular monitoring and tedious operation are reduced, and the
system is timely and accurate and has strong anti-interference capability.
