Abstract
The invention relates to a fixed spray flue gas purifying device, particularly to a device for purifying flue gas generated by a domestic waste combustion furnace, and belongs to the technical field of environmental protection equipment. The fixed spray flue gas purifying device mainly comprises a water tank, a deacidification raw material tank, a semi-dry reaction tower, a fixed spray gun, a first fly ash conveyor, an ash storage bunker, an intermediate flue duct, an active carbon storage bunker, a first conveying blower, a Ca (OH)2 dry powder storage bunker, a second convey blower, a second fly ash conveyor, a bag type dust remover, an induced draft fan, a chimney, a tail end flue duct, a third pipeline, a fourth pipeline and an active carbon measuring and feeding device. The device is simple, compact and reasonable in structure, the size of a spray nozzle of the fix spray gun is small, the mounting and maintenance is convenient, and the cost is lower; the reaction tower not only has high degree of finish but also has higher corrosion resistance and wearing resistance, so that the service life is prolonged; standby deacidification equipment is provided to prevent that emission of acid exceeds the standard; and the adsorption efficiency of Dioxin, heavy metal and other harmful pollutants is improved.
Description
technical field [0001] The invention relates to a fixed spray flue gas purification device, in particular to purify the flue gas produced by domestic garbage incinerators, and belongs to the technical field of environmental protection equipment. Background technique [0002] In the prior art, the tail gas produced by the domestic waste incinerator must enter the flue gas purification device for flue gas purification. The flue gas purification can only remove acidic substances and dust, and there is no backup deacidification means. The activated carbon powder cannot be accurately measured or fully mixed by using an ordinary feeder to supply the activated carbon powder. The reaction tower atomization device in the flue gas purification device adopts a high-rotating sprayer, which mainly injects lime slurry and industrial water to form a rotating liquid mist, which strongly mixes and reacts with the spirally moving flue gas. The high-rotation sprayer consists of a sprayer whee...
