Description
Technical field
The utility model relates to a kind of desulfurizer, especially can effectively remove the limestone-gypsum wet flue gas desulfurizer of toxic gas in the flue gas.
Background technology
At present, known desulfurizer generally can only once filter flue gas, and the time that flue gas contacts with filtered fluid is short, can not fully remove the toxic gas in the flue gas, filters incomplete flue gas and enters in the atmosphere, brings threat for people's health.
The utility model content
Can not effectively remove the problem of toxic gas in the flue gas in order to solve existing flue gas desulfur device, the utility model provides a kind of limestone-gypsum wet flue gas desulfurizer, this limestone-gypsum wet flue gas desulfurizer can carry out twice absorption and filtration to toxic gas, the time that filtered fluid contacts with flue gas is long, sufficient reacting, effectively remove to reduce the content of toxic gas in the flue gas, guaranteed people's health.
The technical scheme that its technical problem that solves the utility model adopts is: this limestone-gypsum wet flue gas desulfurizer is provided with the desulfurizing tower of tubular, bottom one lateral buckling of desulfurizing tower forms the first flue gas purifying area, the bottom of desulfurizing tower links to each other with the hydrops pond by connecting pipe, bottom, hydrops pond is connecting the pump I successively, the bottom of flowmeter I and recycle slurry liquid pool, recycle slurry liquid pool and fresh slurries pond are spaced from each other by dividing plate, dividing plate is provided with the open-work that clear liquid is seen through, be lime stone slurry in the fresh slurries pond, fresh slurries pond is communicated with a plurality of shower nozzles by pump II and flowmeter II, be provided with the spray net between each shower nozzle, shower nozzle also is connected with the slaking liquid pool, be provided with the pump III communicating pipe, in addition, the top of described desulfurizing tower is provided with demister; The inner tower wall of described desulfurizing tower bottom is provided with water yield control point, remind operating personnel with water surface control between two water yield control points, so that gas enters and the resistance when leaving liquid is not too large.During use, coal-fired flue-gas enters the primary purification district from the bottom of desulfurizing tower, reacting in primary purification district and lime stone slurry in the coal-fired flue-gas, enter desulfurizing tower top after filtering, open pump II and pump III, lime stone slurry in the fresh slurries pond and the slaking liquid in the slaking liquid pool mix with flue gas by shower nozzle, carrying out in the flue gas filtered for the second time, the cleaning flue gases that filtration is finished is discharged from desulfurizing tower top, enter atmosphere, the lime stone slurry that falls from shower nozzle enters the hydrops pond, open the pump I, the slurries in the hydrops pond enter in the recycle slurry liquid pool, and in the recycle slurry liquid pool precipitated and separated, the open-work that separated liquid supernatant sees through on the dividing plate enters fresh slurries pond, realizes the recycling of slurries.
The beneficial effects of the utility model are, this limestone-gypsum wet flue gas desulfurizer can carry out twice absorption and filtration to toxic gas, and the time that filtered fluid contacts with flue gas is long, sufficient reacting, effectively remove to reduce the content of toxic gas in the flue gas, guaranteed people's health.
