A washing treatment system includes an odor and flue gas washing tower, a biological deodorization filtering tower, a multifunctional biomass combustion boiler, a liquid fermentation reactor, a solid fermentation reactor, circulating pumps, an exhaust fan and an induced draft fan. An exhaust port is formed in a top end cover of the odor and flue gas washing tower. A liquid inlet, an air inlet and a liquid drainage port are formed in a side wall of a tank body. A hanging basket is placed in the tank body. Organic fillers and/or inorganic fillers are placed in the hanging basket. An inner cavity of the washing tower is divided into a liquid inlet shunting cavity, a filler layer, an air cavity and a liquid accumulation cavity from top to bottom. An upper supernatant in the liquid fermentation reactor is connected with the liquid inlet for washing.

In a nozzle block, a fluid is uniformly sprayed over an entire housing inside through a spray nozzle with the rotation of a nozzle coupling part, thereby increasing a contact ratio of the fluid with contaminated gas and dramatically improving the purification efficiency. Additionally, a fluid for cleaning contaminated gas is allowed to flow opposite to a flow of contaminated gas, so that the contaminated gas and the fluid cancel out, and the contact ratio increases.

Enhanced acid gas removal within a gas processing system

A gas processing system is described herein. The gas processing system includes a number of co-current contacting systems configured to contact a sour feed gas stream including an acid gas with a solvent stream to produce a partially-sweetened gas stream and a rich solvent stream including an absorbed acid gas. At least one of the co-current contacting systems is configured to send the rich solvent stream to a regenerator. The regenerator is configured to remove the absorbed acid gas from the rich solvent stream to produce a lean solvent stream. The gas processing system also includes a solvent treater configured to treat at least a portion of the lean solvent stream to produce an enhanced solvent stream, and a final co-current contacting system configured to contact the partially-sweetened gas stream with the enhanced solvent stream to produce a partially-loaded solvent stream and a final gas stream.
