Description
Technical field
The utility model relates to a kind of desulfurating dust removing device for flue gas, is specifically related to a kind of self-excitation bathing desulfurizing dust-collector dried, wet dust catcher that integrates.
Background technology
Deduster is a kind of discharged flue gas such as boiler, metallurgical furnace kiln to be made the equipment of desulfurization, dust removal process, according to the difference of dedusting technology, can be divided into two big classes: dry type and wet type.So-called dry type, include a cyclone dust removal chamber, flue gas is fed in the cyclone dust removal chamber, utilize whirlwind to carry out centrifugation, because the assorted slag of dust and so on is heavier, fall to the collection ashpit of bottom, and purified gas is just discharged by the outlet pipe at top, and this type of occupation area of equipment is little, and operating cost is low, but the effect that does not have desulfurization does not reach people to environmental protection requirement; The desulfurizer of another kind of wet type, it includes the medical liquid spraying head, by to flue gas injection alkalescence soup, sulphur-containing substance reaction with in the flue gas realizes desulfurization, and the gas after the desulfurization is discharged by air-introduced machine, the cigarette air channel at top, though this wet desulfurizer can be realized desulfurization, but because volume is bigger, water consumption is big, the operating cost height, and, its dust removing effects is not good, need dispose the deduster collaborative work separately usually, causes the increase of cost.
For realizing dedusting preferably and desulfurized effect, people consider with two kinds of textural associations together.China utility model patent CN2288353Y discloses a kind of dry-wet integratedization flue gas desulfurization and dedusting equipment, it is made up of the molecular cyclone chamber of whirlwind, dust collection chamber, doctor solution shower nozzle, smoke tube and the doctor solution circulatory system, flue gas at first adopts the dedusting of cyclone centrifugal separation mode in cyclone chamber, enter the gas liquid reaction chamber again, contact with smoke convection is reverse by shower nozzle ejection doctor solution, absorb sulfide, and the doctor solution that sprays uses by the recovery of the doctor solution circulatory system, regeneration cycle.This fit cleaner of doing, wet can be realized dedusting and desulfurization simultaneously, and can save floor space and maintenance cost; But owing to adopt the injection realization desulfurization of shower nozzle to flue gas, it is very big to leave in the gas of gas liquid reaction chamber water content, in air-introduced machine, cigarette air channel discharge process, remaining sulfide can form acid vaporific atmosphere, air-introduced machine and cigarette air channel contact with sour gas for a long time, very easily corroded, reduced the service life of equipment.
Summary of the invention
The utility model purpose provides a kind of dried, wet dust catcher advantage that has concurrently, and long service life is discharged The Emissivity of Gas lingemann grade number at 0～1 grade, water-saving self-excitation bathing desulfurizing dust-collector.
For achieving the above object, the technical solution adopted in the utility model is: a kind of high-efficiency water-saving desulfurizing dust-collector, it by housing, be located at housing one side smoke inlet, be located at case top exhanst gas outlet, be positioned at the collection ashpit of housing below and add the alkali pond and form, described housing inner route clapboard is divided into dried dedusting area, desulfurization zone and drying zone, be provided with cyclone dust collectors in the described dried dedusting area, the bottom of cyclone dust collectors is communicated with the collection ashpit, and the top is communicated with through exhaust gases passes with desulfurization zone; The outlet of desulfurization zone is communicated with drying zone; Described drying zone is connected with exhanst gas outlet, be provided with an air-introduced machine between described exhaust gases passes and the desulfurization zone, the inlet of air-introduced machine is positioned at the exit of exhaust gases passes, and outlet is positioned at the porch of desulfurization zone, and become 30 °～80 ° angle between the gas channel direction in the desulfurization zone and the horizontal plane that adds the alkali pond, described drying zone is positioned at the top of desulfurization zone.
In the technique scheme, described desulfurization zone is the interconnection of a connection blower fan and drying zone, the roof of passage is provided with a baffle plate, one end of baffle plate is fixed on the roof, the other end and add between the horizontal plane in alkali pond and constitute Striker, angle between described baffle plate and roof downbeam is between 30 °～90 °, and the height of described Striker is not more than 20cm.
Another kind of technical scheme is, the exit flow passage of described air-introduced machine is in tilted layout, and becomes 30 °～80 ° angle between exit flow passage and the horizontal plane that adds the alkali pond.
In the technique scheme, be provided with at least 2 dewatering plates in the described drying zone, an end left and right sides of described each dewatering plate is arranged in a crossed manner on the tube wall of drying zone both sides, and the other end is unsettled, and unsettled place and tube wall constitute the dehydration passage.
In the technique scheme, described air-introduced machine and adding on the lateral wall of the housing between the alkali pond is provided with one and adds the alkali mouth, describedly adds the alkali mouth and adds the alkali pond and be communicated with.When the alkaline concentration in adding the alkali pond drops to certain value, can directly add alkali from adding the alkali mouth, it is convenient to add alkali.
In the technique scheme, the bottom outside of described housing adds the outside in alkali pond, is provided with an ash hole.Ash hole constitutes automatically and artificial two kinds of ash discharge modes with the collection ashpit, makes things convenient for ash discharge.
The utility model operation principle is: feed in the cyclone dust collectors of doing dedusting area by smoke inlet at flue gas, under the whirlwind mouth effect of tilting, make the flue gas that enters form spirality, heavier dirt slag falls into the dust pond in action of centrifugal force, and the flue gas that removes the dust removal slag is through exhaust gases passes, under the effect of air-introduced machine, acceleration enters the desulfurization passage, and flue gas is subjected to blocking of baffle plate, or, rush at the horizontal plane that adds the alkali pond to become 30 °～80 ° inclination angle with horizontal plane by the restriction of air-introduced machine Way out, evoke a large amount of water droplets and foam, with the flue gas hybrid reaction, reach dealkalize, flue gas after being purified rises and enters drying zone, impinges upon on the dewatering plate, because the flue-gas temperature of this moment is higher, run into the bigger dewatering plate of its temperature difference after, aqueous vapor unnecessary in the flue gas is liquefied as water, drips back to add in the alkali pond, and through the dehydration of at least 2 dewatering plates, drying, desulfurization, the gas of dedusting is discharged from exhanst gas outlet.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1. owing to include in the utility model and do dedusting area and desulfurization zone, doing in the past, wet dust catcher are merged into a single whole, had both both advantages, and replaced the injecting type desulfurization with auto-excitation type, desulphurization reaction is more thorough, need not to establish in addition sedimentation basin, has avoided secondary pollution.
2. because air-introduced machine is located between dried dedusting area, the desulfurization zone, the flue gas that enters air-introduced machine is not with water, has avoided acid vaporific atmosphere or aqueous vapor to the corrosion of air-introduced machine, has prolonged service life.
3. the utility model utilizes cyclone dust collectors to remove dirt slag in the flue gas earlier, accelerate to enter the flow velocity of desulfurization zone flue gas again by air-introduced machine, make it fully answer desulfurization with auto-excitation type and alkali lye, remove excessive moisture by dewatering plate at last, therefore the dedusting desulfurization of discharging is thorough, blackness woods lattice Manda to 0～1 grade.
