Description
The utility model relates to a kind of equipment that ash-laden gas is handled, and particularly relates to a kind of device that can carry out effectively dustproof, desulfurization, dehydration to boiler smoke etc.
In China, efforts at environmental protection have caused people's great attention.The ash-laden gas of generations such as coal-burning boiler has become the emphasis of improvement.At present, the treatment technology of exploitation is also many, wet method is arranged, do wet method etc., and its characteristics are respectively arranged.But majority influences its popularization because of complex structure, cost height or desulfurization and dedusting effect are undesirable.
The purpose of this utility model provides a kind of simple in structure, flue-gas dust-removing and desulfurization device that dust-removal and desulfurizing is satisfactory for result.
The utility model places between ash-laden gas pipeline and the chimney, it includes housing, air-introduced machine, open at the smoke inlet on housing top and be positioned at the high-pressure nozzle of housing internal upper part, in housing, be positioned at smoke inlet below directly be the separation chamber, be provided with water inlet pipe and several layers of moisture film groove in the separation chamber, the moisture film groove is the inclination angle of 6-12 degree and arranges, the moisture film groove of each layer is parallel to each other or is substantially parallel, on, lower floor's moisture film groove vertical plane is staggered, basically non-overlapping copies, on corresponding, link up by guiding gutter between lower floor's moisture film groove, be connected with feed pipe on the water inlet pipe, each feed pipe lower end is stretched in the corresponding moisture film groove in the superiors, has grey water out and exhanst gas outlet in lower housing portion.When using the utility model, open switch, water inlet pipe switch and the air-introduced machine switch of control high-pressure nozzle.After the water inlet pipe switch opens, each bar moisture film groove of the superiors all can obtain the water supply from feed pipe, water under the superiors' moisture film concentrated flow is guided to second layer moisture film groove by guiding gutter, successively is delivered to bottom water membrane groove more successively, and the grey water out of flowing through is again at last discharged; After the air-introduced machine work, ash-laden gas from boiler flue, smoke inlet on housing, enter from the top of housing inner chamber, the flue gas (about 8 meter per seconds of speed per hour) of going into behind the chamber promptly fully contacts with the vaporific calcium hydroxide alkali lye of high-pressure nozzle ejection, sulfur in smoke generates crystalloid aquation calcium sulfate (2H with after the calcium hydroxide molecule contacts
2O.CaSO
4Be gypsum crystallization), dust in flue gas and aquation crystal of calcium sulfate particulate are with recoil vertically downward moisture film tank systems in the separation chamber of air-flow, be subjected to the head-on interception of moisture film groove in the recoil process, be the direct collision moisture film groove water surface, dust and crystalloid aquation calcium sulfate are tackled by flowing water and heavy soluble in water taking away like this.Because supply water constantly in the groove, every moisture film groove is 6-12 degree angle in addition, current are more anxious, just can not produce obstruction in the groove.Again because the moisture film groove in the utility model Different Plane is the dislocation arrangement, gas then is the ripples shaped form and flows in passing through separation chamber's whole moisture film groove layer, all be subjected to gravity and centrifugal action when having the dirt powder of certain mass and aquation calcium sulfate particulate to turn at every turn, thereby change its flow trace (inconsistent) with airflow direction, increase or increase grit and particulate rushes at the speed of moisture film groove and the probability of crash onto water, thereby improved dedusting, remove a grain effect; This wave gas flow pattern is also quickened the calcium hydroxide in the air-flow and the contact probability of sulfur dioxide, improve desulfuration efficiency, the calcium hydroxide collision of participating in reaction is deposited in the moisture film groove and the sulfur trioxide neutralization reaction in the water, can solve the secondary pollution problem of wet dust removal.In above-mentioned dust-removal and desulfurizing process, the steam that forms in the gas can be partially absorbed by current because of collision on lower floor's moisture film groove.Ash-laden gas can reach good dust-removal and desulfurizing effect by behind the above-mentioned separation chamber, and dedusting can reach about 90%, and desulfurization reaches 50% approximately.
Another design feature of the utility model is, in housing, also be provided with another independently and the also identical separation chamber of internal structure with aforementioned separation chamber, this separation chamber is provided with water inlet pipe and moisture film tank systems in (i.e. second separation chamber) equally, is tandem with aforesaid separation chamber and is communicated with.The purpose that tandem also is provided with second separation chamber is to make by first separation chamber to handle the back flue gas, carries out dedusting again, removes grain, processed, further improves the disposal ability of equipment, makes its dedusting threshing dehydrating effect reach optimum state.Flue gas is after the said process of first separation chamber is handled, escape and enter two by the exhanst gas outlet of being located at the bottom and separate the exhaust gases passes ascent stage that forms between locular wall, in uphill process, dirt powder, gypsum crystallization particulate and steam residual in the gas progressively concentrate or gathering mutually because of gravitate, enter the separation chamber from second separation chamber's upper entrance then, this air-flow moisture film tank systems that recoils vertically downward again, atomized steam in the air-flow and remaining grit, crystal fine grain are collided by the moisture film groove repeatedly and are absorbed by current eventually.
The utility model design feature again is that second separation chamber's cross-sectional area is greater than the cross-sectional area of first separation chamber.Sectional area can reduce gas flow rate after increasing, and improves dedusting, threshing, dehydrating effect.Through the flue gas that second separation chamber bottom exhanst gas outlet is discharged, dust removing effects can reach more than 99% after tested, and desulfurization reaches about 55%, and moisture-free almost.
The utility model is compared with existing dust arrester has following advantage:
1. the efficiency of dust collection height can reach more than 99.5%, in 0.5 grade of the Lin Geman dark brown; Desulfurized effect reaches 55%.
2. the flue gas flow rate of the utility model structure and resistance are all smaller; Flue dust in the flue gas and sulfur dioxide corrective are all soluble in water, taken away by current, and the water after sinking clearly can recycle; Flue gas after treatment is moisture-free almost, and air-introduced machine can be with water running.
3. can dust stratification in the utility model body, can not result in blockage.
4. simple in structure, safeguard very conveniently, safeguard during annual maintenance boiler once to get final product.
5. adopt the granite processing and fabricating, reach service life more than 10 years.
6. cheap, investment is not as good as 1/2nd of electrostatic precipitator.
7. applied widely, all can use from civilian little cooking stove to 0.5T-130T industry, electric boiler.Be specially adapted to large, medium and small cities and towns and all boiler, stoves that the heat supply fire coal is arranged.
