Description
Technical field
The present invention relates to a kind of environmental protection equipment, is a kind of high-efficiency flue gas desulfurization dedusting and purifying device.
Background technology
The flue gas desulfurization and dedusting purifier has many kinds, but how to turn to wet scrubber by dry collector in recent years, is because the wet scrubber volume is little, less investment, and operating cost is lower, and purification efficiency is than higher.But topmostly still carry out flue gas desulfurization simultaneously owing to can utilize water in the hydrofilter to add some alkaline matters.Mainly be to utilize water film dedusting, Venturi scrubbing etc., the method that adds spray is carried out dedusting and desulfurization.These methods mainly contain following defective:
1) air water mixes, and needs a large amount of absorption liquids, and this is a no small operating cost;
2) owing to adopt spraying method, cause the gas water content that is discharged to increase, and will contain sweetening substance in the gas of discharging;
3) time along with the equipment operation increases, and the mixing mud quantity of dust and absorption liquid increases, and can cause the increase of place area occupied like this;
4) use wet desulphurization, absorption liquid can not in time reclaim.
Summary of the invention
Zhen Yu has dust-removal and desulfurizing equipment defective technically now, the invention provides a kind of high-efficiency flue gas desulfurization dedusting and purifying device.This flue gas desulfurization and dedusting purifier is simple in structure, easy to use, purification efficiency is high.Can eliminate the generation of secondary pollution, be a kind of green environmental protection technique.
The present invention realizes that the technical scheme of above-mentioned purpose is: a kind of high-efficiency flue gas desulfurization dedusting and purifying device, wherein deduster and desulfurization passage link together, the deduster inlet joins with the impact water bath passage, the upper spacer and the lower clapboard that are separated into 2 spray chambers in the deduster casing are formed a S shape passage, outlet is connected and the steam trap that is installed in deduster casing top is with deduster, the machine of scratching in the ashes that is installed in the deduster bottom communicates with liquid in the deduster, and an end of the desulfurization passage of built-in swirler closely is installed in the deduster outlet.The desulfurization passage is the swirler that the chemical desulfurization agent is housed in flue body.At first, be to purify dust in flue gas, then sulfur-containing smoke gas is carried out desulfurization and handle.
Enter the impact water bath passage of this device when flue gas after, utilize the flow velocity of flue gas, at first impact liquid in the casing, cause liquid splash in the casing, in casing, cause certain density water smoke phenomenon, at this moment, most of dust sink in impact in the casing in the liquid, and tiny grit collides in water smoke in the flue gas, also crash in succession after soaking in the interior liquid of casing, meanwhile, the remaining flue gas that has not purified is forced to pass through from S shape passage, and S shape passage is to be made of upper spacer and lower clapboard, simultaneously, upper spacer and lower clapboard are divided into two spray chambers with the deduster casing.Flue gas is on suffering, during the interception of lower clapboard, liquid in the casing is produced impact, self-excitation phenomena takes place again, the water smoke phenomenon is denseer in the casing, another part grit sinks in the interior liquid of casing, because the percussion of flue gas, this moment, S shape passage formed cascade one, and sub-fraction dust remaining in the flue gas is blocked by cascade the time, crashed in the interior liquid of casing, when after flue gas is by S shape passage, entering spray chamber, this moment, dust in flue gas had only the particulate of minute quantity, and they with hydrone in the spray chamber fierce collision take place, and form the dust-laden droplet and crash in the interior liquid of casing, the same with other dust, sink to the bottom in the liquid in the casing, the machine of scratching in the ashes that is installed in lower box is scavenged into external, fully utilizes, and in the gas cleaning process, the loss of liquid is then replenished by water supply tank in the casing.By the catharsis to exhaust gas dust, the dusty gas in the flue gas reduces to about 0.1%, and they are blocked, adsorb a part again with the droplet state by steam trap the time, and this moment, the flue gas by steam trap entered the desulfurization passage through the outlet connecting pipe road.In fact, for making sulfurous gas obtain the best purification condition, when flue gas passes through steam trap in the dust removal process neutralization, its temperature has obtained cooling and has handled, flue gas is after passing through steam trap, its temperature is near normal temperature, these are near the sulfurous gas of normal temperature, enter the desulfurization passage after, suffer that swirler stops continuously, make sulfurous gas produce eddy current, cause gas molecule to collide continuously, the free path of sulfurous gas molecule is increased, like this, to being installed in interior self-control chemical desulfurization agent of swirler and sulfurous gas molecule, make sulfurous gas striven fully to satisfy the affine time.
This installs mentioned desulfurizing and purifying passage is one whole section flue, also can be the assembly of multistage flue, decide according to sulfur content in the gas; This installs mentioned swirler, is that several also can be dozens ofs, and they are by the sheet material that has hole, crack, also can be to be made by a plurality of tubing, bar; The mentioned self-control chemical desulfurization agent of this device can be changed at any time.So far, the gas cleaning process is all over, and the flue gas through purifying has become the gas of white clouds shape cleaning to enter atmosphere.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is the deduster cutaway view of a kind of embodiment.
Fig. 2 is the desulfurization passage cutaway view of this embodiment.
The specific embodiment
Referring to accompanying drawing, the casing 13 of the deduster 1 in the high-efficiency flue gas desulfurization dedusting and purifying device provided by the invention is a cuboid, it also can be cylinder, the impact water bath passage 3 that is connected with smoke inlet is rectangular ducts, it also can be columniform pipeline, its end is open shape, be convenient to the diffusion of air-flow, impact water bath passage and S shape passage 8 are divided into two spray chambers 7 by upper spacer 5 and lower clapboard 10 with the deduster casing, the flue gas that comes out from the impact water bath passage will impact liquid 9 in the casing and and in the casing liquid mix, stir the back by S shape passage, bump water fender 62 flows into desulfurization passages 14 through steam trap 4 from the outlet connecting pipe road, under being captured, dust in flue gas crashes into liquid bottom in the casing in deduster, it is external that the machine 11 of scratching in the ashes is removed deduster with it, and the moisture content that is consumed in purification process is then replenished by water supply tank 12; Desulfurization passage provided by the invention is one section rectangular duct, also can be to combine by several segment pipes, containing sulphur concentration in the desulfurization vias inner walls according to gas, several are installed also can be tens swirlers 15, these swirlers be regularly, symmetrically, staggered and install equably, swirler is to be made by the sheet material in crack with holes, also can be the combination by a plurality of tubing, bar, the self-control chemical desulfurization agent 16 that is placed in the swirler can be changed easily.
The position symmetry of the swirler in the described desulfurization passage and staggered, all be as the criterion with the axle center of desulfurization passage and the center of desulfurization channel cross-section, described desulfurization channel cross-section shape can be that toroidal also can be rectangular-shaped, and the upper spacer and the lower clapboard of S shape passage are rectangular plate shape in the described composition deduster casing.
