Description
Technical field
The utility model relates to a kind of spray fume desulfurizing tower.The utility model can be applicable to industry, technical field such as civilian, can be applicable to produce in the production processes such as power plant, chemical plant and steel mill places such as the industrial enterprise of a large amount of flue gases and central heating boiler room especially.
Background technology
Fume desulfurizing tower is to be used for removing the sulfur in smoke that fired coal combustion produces.Sulfur dioxide reduces discharging and be listed in a very important major issue in environmental protection, and the discharge capacity of China's sulfur dioxide in 2006 has occupied the first in the world.The sulfur dioxide of a large amount of dischargings use solid fuel from each industry of the whole world and civilian users and the flue gas that produces.A large amount of sulfur dioxide is discharged in the atmosphere can form acid rain, destroys earth ecology, and environmental protection is brought totally unfavorable influence.And that existing wet flue gas desulfurization tower has is following several: the spray desulfurizing tower that 1) adopts rotarytype injector, it comprises: housing, atomising device and demister, housing inner chamber bottom is a liquid storage cylinder, housing inner chamber middle part is the desulfurization chamber, housing inner chamber top is the demist chamber, demister is located in the demist chamber, liquid storage cylinder has discharging opening, bottom, desulfurization chamber has gas approach, and case top has exhanst gas outlet, and atomising device is by the liquid pressue device, liquid line and rotarytype injector are formed, rotarytype injector is positioned at the desulfurization top of chamber, spout is provided with down, and the liquid pressue device is located at outside the housing, and rotarytype injector is connected with the liquid pressue device by liquid line.The spray desulfurizing tower that adopts rotarytype injector in use, sweetening liq such as lime stone solution by the pressurization of liquid pressue device after liquid line by the rotarytype injector ejection that nebulizes, reacts the purpose that reaches desulfurization with sulfur in smoke again.This rotarytype injector mainly is by the centrifugal action of liquid is realized to the atomizing of sweetening liq.Adopt the advantage of the spray desulfurizing tower of rotarytype injector to be: rotarytype injector wherein is good to the atomizing effect of sweetening liq, the desulfuration efficiency height; Shortcoming is: rotarytype injector is very easily blocked and wear up to and loses atomizing, causes desulfuration efficiency to descend, and nozzle life is short, needs often to shut down to change, and influences production efficiency, and this kind nozzle mainly relies on import, and cost is higher.The reason that rotarytype injector stops up mainly is that the runner of liquid is narrower in the nozzle, and the desulfuration solution that is adopted---lime stone solution is emulsion and contains the tiny solid particle and can stop up runner, and contained alkaline matter can be due to the fouling of nozzle inner walls face in the liquid.The reason of rotarytype injector wearing and tearing is: for reaching atomizing effect preferably; the flow velocity of desulfuration solution in nozzle needs higher; the solid particle of desulfuration solution high speed motion can be done curvilinear motion in action of centrifugal force lower edge nozzle inner walls; bigger friction taking place so that serious wearing and tearing take place for it with nozzle inner walls, causes the nozzle breakage.2) spray column of the compound jet pipe atomizing of employing sweetening liq, it is compared with the spray desulfurizing tower that adopts rotarytype injector, and only atomising device is different, adopt the atomising device of the spray column of compound jet pipe atomizing sweetening liq to form by compound jet pipe, gas pressurized device and liquid pressue device, compound jet pipe is composited by interior pipe and outer tube coaxial, in the same way, the interior pipe of compound jet pipe is connected with the liquid pressue device, and the outer tube of compound jet pipe is connected with the gas pressurized device.The spray column that adopts compound jet pipe atomizing sweetening liq in use, the interior pipe inspection sweetening liq such as the lime stone solution of compound jet pipe wherein, and the outer tube injection air of compound jet pipe, utilize interaction between forced air and the sweetening liq to realize the atomizing of sweetening liq, sweetening liq after being atomized and sulfur in smoke are reacted to remove sulfur in smoke.Adopt the spray column advantage of compound jet pipe atomizing sweetening liq to be: compound jet pipe wherein is good to the sweetening liq atomizing effect, the desulfuration efficiency height; Shortcoming is compound jet pipe processing technology complexity, and nozzle wall very easily weares and teares, and is destroyed, and nozzle life is short, influence the atomization of liquid, and desulfuration efficiency descends, and sometimes even just needed replacing in several days, causes the instability of desulfurized effect, influences production efficiency.The reason of compound jet pipe cracky also is due to swiftly flowing solid particle and the nozzle wall generation strong friction.The runner of liquid is narrower in the compound jet pipe, and will have a certain degree with its axis usually, and sweetening liq is done curvilinear motion in jet pipe, and the strong friction that swiftly flowing solid particle and nozzle wall take place causes compound jet pipe breakage.3) the fluid column formula spray column of employing straight tube, it is compared with the spray desulfurizing tower that adopts rotarytype injector, and only atomising device is different, adopts the atomising device of the fluid column formula spray column of straight tube to be made up of straight tube and liquid pressue device.The fluid column formula spray column of employing straight tube in use, straight tube wherein mainly is by the straight tube injection desulfurization liquid that makes progress to the atomizing of sweetening liq such as lime stone solution, sweetening liq interacts with flue gas on every side when falling after rise by the gravity effect, realizes to the atomizing of sweetening liq and to the desulfurization of flue gas.The advantage that adopts the fluid column formula spray column of straight tube is that wherein straight tube is simple in structure, and it is little to wear and tear, long service life; Shortcoming is that the mutual friction force of sweetening liq and surrounding air is little, and atomization of liquid specific area is little, and atomizing effect is relatively poor, and desulfuration efficiency is not high.
