The invention discloses a method for removing acid gas in flue gas by utilization of a spray tower and adoption of red mud serum as an absorbent, which comprises the following steps: 1) allowing the flue gas to enter an absorption area of the spray tower through an air inlet, and purifying the flue gas in the tower by making the flue gas contact vaporific red mud serum sprayed from one or more of spraying layers and oxidized gas introduced from the bottom of the spray tower during the lifting of the flue gas; 2) allowing the flue gas purified in the tower to penetrate through a demister on the upper part of the spray tower so as to remove small vaporific liquid droplets carried by the flue gas and generate pure flue gas, and directly exhausting the pure flue gas to the atmosphere or exhausting the pure flue gas to the atmosphere through a chimney which is arranged outside the tower; and 3) sending the red mud serum purified in the tower from the bottom of a red mud serum tank to an exhaust system for exhausting or stacking, wherein the red mud serum is added or replenished through a red mud serum pipeline during purification treatment.

The invention provides a treatment system of smoke organic waste gas produced in circuit board disassembly. The treatment system of the smoke organic waste gas produced in the circuit board disassembly comprises a lime storage tank, a dry method lime spray tower, a pulsed bag-type dust remover, an activated carbon adsorption tower, a first fan and a second fan, wherein pulsed control ash removal equipment is installed on the upper portion of the pulsed bag-type dust remover; multiple nozzles communicated with an inner cavity of the dry method lime spray tower are arranged in the middle of an enclosure bulkhead of the dry method lime spray tower, the nozzles are connected with an exhaust opening of the first fan through pipelines, a discharge opening in the bottom of the lime storage tank is connected to the pipeline between the nozzles and the exhaust opening of the first fan through a gate valve and a pipeline, a waste gas inlet is formed in the lower portion of the enclosure bulkhead of the dry method lime spray tower, the bottom of the dry method lime spray tower is provided with an ash hopper for collecting waste materials, and the top of the dry method lime spray tower is provided with a spray tower gas outlet. By means of the treatment system of the smoke organic waste gas produced in the circuit board disassembly, the treatment efficiency of the smoke dust treatment system is effectively improved, and the treatment cost is reduced. Meanwhile, by means of the adsorption of activated carbon on volatile organic matter and off-flavors, the total purification efficiency of the organic waste gas treatment system is improved.

The invention provides an energy-saving device of a wet desulphurization spray tower. The device is arranged on the tower wall of the wet desulphurization spray tower between an inlet of the wet desulphurization spray tower and a lowermost spray layer. The energy-saving device comprises a reinforcing plate fixed on the inner side of the tower wall, a bottom plate connected with the reinforcing plate, a side plate installed on the inner side of the bottom plate, pull rods, a sealing plate, vent pipes and flow guide plates; at least two pull rods are arranged between the side plate and the bottom plate; two ends of each pull rod are respectively connected with the inner wall of the side plate and the upper wall of the bottom plate; the inclined sealing plate is welded between the lower bottom surface of the bottom plate and the tower wall; at least two vent pipes are arranged on the tower wall below the bottom plate; the flow guide plates are arranged at two ends of the bottom plate; oneend of each flow guide plate is connected with the reinforcing plate, and a liquid discharge outlet is formed between the other end of each flow guide plate and the side plate. With the device adopted, the problem of accumulation of solids at the inlet of the tower can be effectively solved, a waterfall phenomenon can be avoided, flue gas resistance can be reduced, and energy conservation can berealized.

The invention discloses an ethanol recovery system, which comprises a first spray absorption tower and a second spray absorption tower. The first spray absorption tower comprises a first tower body, a first gas inlet formed in the first tower body, a first gas outlet formed in one end of the first tower body, and a first spray head arranged in the first tower body and close to the first gas outlet. The first gas outlet is far away from the first gas inlet. The second spray absorption tower comprises a second tower body, a second gas inlet formed in the second tower body, a second gas outlet formed in one end of the second tower body and a spray group arranged in the second tower body and close to the second gas outlet. The spray group comprises a second spray head and a third spray head which are sequentially arranged in the gas flow direction in the second spray tower. The second gas outlet is far away from the second gas inlet. The first gas outlet is connected with the second gas inlet through a pipeline. By additionally arranging a spray head in the second spray absorption tower, the absorption frequency of ethanol in the tail gas is increased, and the ethanol absorption effect is improved.
