Abstract
The utility model discloses a flue gas demisting device for a desulfurization tower. The desulfurization tower comprises a tower body, an air inlet, a circulating pump, a spray pipe and a demisting device, wherein the air inlet is formed in the middle section of the tower body; the circulating pump is arranged at the lower section of the tower body; the circulating pump pumps slurry at the tower bottom to the spray pipe; the demisting device is horizontally arranged at the upper end of the tower body; the demisting device consists of multiple groups of fixed brackets, a block piece and a movable bracket capable of moving along the tower body; the two ends of the fixed bracket are fixed on the tower body; the upper end of the block piece is fastened on the fixed bracket; the block piece can rotate along the fixed bracket; and the lower end of the block piece is rotatably fastened on the movable bracket. By adopting the scheme, when the demisting device needs flushing, by moving the movable block piece to different positions, a flushing device can thoroughly flush the block piece to eliminate dirt attachment for sure; and meanwhile, by adjusting the angle of the block piece, the airflow and flue gas demisting rate also can be controlled.
Description
Technical field
The utility model relates to the environment protection desulphurization technical field, and desulfurizing tower technology especially is specifically related to be used for the flue gas demister of desulfurizing tower.
Background technology
Lime stone---gypsum method sulfur removal technology is most widely used in the world a kind of desulfurization skill wet desulfurizing process flow chart art, and the flue gas desulfur device about 90% that adopt in the thermal power plant of Japan, Germany, the U.S. adopts this technology.Its operation principle is: agstone is added water make slurries and pump into the absorption tower as absorbent and fully contact mixing with flue gas, calcium carbonate in sulfur in smoke and the slurries and the air that blasts from the tower bottom carry out oxidation reaction and generate calcium sulfate, after calcium sulfate reached certain saturation degree, crystallization formed dihydrate gypsum.The gypsum slurries of discharging through the absorption tower through concentrate, dehydration, make its water content less than 10%, deliver to the gypsum bunker with conveyer then and stack, the flue gas after the desulfurization is removed droplet through demister, pass through the heat exchanger heat temperature raising again after, enter atmosphere by chimney.
The catch of existing flue gas demister mostly is fixed structure, when big drop is assembled in the catch inboard sedimentation meeting taking place produces dirt, though most equipment also are equipped with the fountain flusher, be difficult to clean to the dirt of ground floor inboard, for the easy cleaning not especially of the catch on the flue gas demister of the second layer.
The utility model content
At the problems referred to above, the utility model aims to provide the mobilizable flue gas demister of being convenient to clean that is used for desulfurizing tower of a kind of catch.
For realizing this technical purpose, scheme of the present utility model is: a kind of flue gas demister that is used for desulfurizing tower, described desulfurizing tower comprises tower body, air inlet, circulating pump, shower, demister, air inlet is arranged on the stage casing of tower body, the tower body hypomere is provided with circulating pump, circulating pump is evacuated to the suction shower with tower prime cement liquid, demister is horizontally set on the tower body upper end, described demister is by the plural groups fixed support, catch, can form along the travel(l)ing rest of tower body activity, the fixed support two ends are fixed on the tower body, the catch upper end is buckled on the fixed support, and catch can rotate along fixed support; The catch lower end is rotating to be buckled on the travel(l)ing rest.
As further improvement, the demister that is provided with in the described tower body is two-layer, and the catch direction of every layer of demister is opposite.
As further improvement, described tower body upper strata also is provided with cleaning hose, and cleaning hose also is connected with water tank.
The beneficial effects of the utility model are: when demister need wash, just can guarantee that by catch to the diverse location with activity flusher can be clean with the catch cleaning down, eliminate dirt and adhere to; By regulating the catch angle, also can control the demist rate of air-flow and flue gas simultaneously.
Description of drawings
Fig. 1 is the structural representation of demister of the present utility model;
Fig. 2 is the structural representation of the related desulfurizing tower of the utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
As Fig. 1, shown in 2, a kind of flue gas demister that is used for desulfurizing tower of the present utility model, described desulfurizing tower comprises tower body 1, air inlet 2, circulating pump 3, shower 4, demister 5, air inlet 2 is arranged on tower body 1 stage casing, tower body 1 left side is provided with circulating pump 3, circulating pump 3 is pumped to shower 4 with tower prime cement liquid, demister 5 is horizontally set on tower body 1 epimere, described demister 5 is by many groups fixed support 8, catch 9, travel(l)ing rest 10 is formed, fixed support 8 two ends are fixed on the tower body 1, catch 9 upper ends are buckled on the fixed support 8, and catch 9 can rotate along fixed support 8; Travel(l)ing rest 10 can be movable up and down along tower body 1, and catch 9 lower ends are buckled on the travel(l)ing rest 10, and catch 9 can rotate along travel(l)ing rest 10.Demister generally adopts anti-flaming polypropylene material to make, and it is minimum that demister can make water droplet content be reduced to, and avoids discharging gas as much as possible and bring dust into.Variation by travel(l)ing rest simultaneously, catch can be in 0 ° of-180 ° of angle any movable adjusting angle.
In order to make the demist better effects if, demister 5 is set for two-layer in the described tower body 1, two-layer demister 5 catch 9 directions separately are opposite.Being crisscross arranged to make air-flow contact with catch more fully, promotes that droplet slowly is condensed into bigger drop, is slipped to the slurries pond along the bottom of catch then.
For ease of flushing operation, described tower body upper strata also is provided with cleaning hose 6, and cleaning hose 6 also is connected with water tank 7.Because flue gas can be taken away water in a part of absorption tower with steam, gypsum crystallization also can consume a part of water, can influence the carrying out of reaction like this; This part water just in time can replenish by the flushing demister; Also can give cooling in the tower in this way simultaneously, avoid the interior temperature of tower too high.
The above; it only is preferred embodiment of the present utility model; not in order to restriction the utility model, every foundation technical spirit of the present utility model to any trickle modification that above embodiment did, be equal to and replace and improve, all should be included within the protection domain of technical solutions of the utility model.
