Abstract
The utility model discloses a desulfurization system for boiler flue gas recovery system connects and to install on boiler flue gas recovery system, and boiler flue gas recovery system is equipped with the water back including coal fired boiler, water -cooled separator, dust remover and condensation energy -saving appliance that pipeline in proper order meets in the condensation energy -saving appliance, desulfurization system is including connecting on the absorption tower at condensation energy -saving appliance rear, and the absorption tower meets with limestone slurry preparation case, storage water tank pipeline, is equipped with on this pipeline to be arranged in preparing the lime stone thick liquid of case, the power pump that the absorption tower was squeezed into to water in the storage water tank with limestone slurry, and the exit end on absorption tower has connected gradually defroster, heat exchanger and chimney. The utility model discloses simple structure, convenient operation, processing system through equipment such as absorption tower, limestone slurry preparation case and storage water tank are constituteed can effectively carry out the desulfurization to waste gas after flue gas waste heat utilization accomplishes, have simple process, advantage that the handling capacity is big.
Description
Technical field
The utility model relates to a kind of boiler smoke recovery system, is specifically related to a kind of desulphurization system for boiler smoke recovery system.
Background technology
Nearly ten years, due to energy shortage, along with energy conservation is carried out further.The various energy-conservation advanced type of furnace is gradually improved, and adopt advanced burner to enhance burning, reduce imperfect combustion amount, air-fuel ratio is also tending towards reasonable.But, reduce the become estranged technology of Mist heat recovering of exhaust gas heat loss and be still in progress unhappy.In order to improve the thermal efficiency of kiln further, reach energy-saving and cost-reducing object, boiler Mist heat recovering is also an important energy saving way.In prior art, boiler Mist heat recovering system is varied, and wherein utilizing waste heat to add heat user water, is a kind of common Land use systems, but after heating completes, and but cannot ensure that the waste gas of discharging can desulfurization comprehensively, cause certain air pollution.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides one after fume afterheat has utilized, effectively can carry out the desulphurization system for boiler smoke recovery system of desulfurization to waste gas.
A kind of desulphurization system for boiler smoke recovery system, be mounted in boiler smoke recovery system, boiler smoke recovery system comprises coal-burning boiler, water-cooled separator, deduster and the condensation energy-saving device that pipeline successively connects, and is provided with water back in condensation energy-saving device; Described desulphurization system comprises the absorption tower being connected to condensation energy-saving device rear, absorption tower and lime stone slurry prepare case, storage tank pipeline connects, this pipeline is provided with for the kinetic pump limestone slurry in case being prepared by lime stone slurry, the water in storage tank squeezes into absorption tower, and the port of export on absorption tower is connected with demister, heat exchanger and chimney in turn.
Further describing as technique scheme:
Described absorption tower is connected with gypsum storage bin by conveyer.
The utility model structure is simple, easy to operate, is prepared the treatment system of the equipment such as case and storage tank composition, after fume afterheat has utilized, effectively can carry out desulfurization to waste gas, have the advantage that technique is simple, treating capacity is large by absorption tower, lime stone slurry.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
See Fig. 1, a kind of desulphurization system for boiler smoke recovery system that the utility model provides, be mounted in boiler smoke recovery system, boiler smoke recovery system comprises the coal-burning boiler 1 that pipeline successively connects, water-cooled separator 2, deduster 3 and condensation energy-saving device 4, water back (not shown) is provided with in condensation energy-saving device 4, described desulphurization system comprises the absorption tower 5 being connected to condensation energy-saving device 4 rear, absorption tower 5 and lime stone slurry prepare case 6, storage tank 7 pipeline connects, this pipeline is provided with the limestone slurry for being prepared by lime stone slurry in case 6, water in storage tank 7 squeezes into the kinetic pump 8 on absorption tower 5, the port of export on absorption tower 5 is connected with demister 9 in turn, heat exchanger 10 and chimney 11.
Its course of work is: after flue gas is discharged from coal-burning boiler 1, enter water-cooled separator 2, deduster 3 completes dedusting, enter condensation energy-saving device 4 again, for the water in water back heats, after having heated, waste gas enters absorption tower 5, agstone adds water and makes slurries and pump into absorption tower 5 as absorbent and fully contact mixing with waste gas, sulfur dioxide in waste gas and the calcium carbonate in slurries and the air blasted from tower bottom carry out oxidation reaction and generate calcium sulfate, after calcium sulfate reaches certain saturation degree, crystallization forms dihydrate gypsum.Flue gas after desulfurization removes droplet through demister 9, then after heat exchanger 10 heat temperature raising, enters air by chimney 11.Because absorption tower 5 inner absorbent slurries are by circulating pump iterative cycles and smoke contacts, absorbent utilization rate is very high, and calcium sulfur ratio is lower, and desulfuration efficiency can be greater than 95%.
In the present embodiment, absorption tower 5 is connected with gypsum storage bin by conveyer.Object is, the gypsum slurries of discharging through absorption tower, through concentrated, dehydration, makes its water content be less than 10%, then delivers to gypsum storage bin with conveyer and stacks, can utilize desulfurization product further, economize energy.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
