Description
Technical field
The utility model relates to a kind of flue-gas dust-removing and desulfurization device, is specifically related to a kind of wet dust removal desulfurizer that is mainly used in Industrial Boiler.
Background technology
At present, the most general method of Industrial Boiler flue-gas dust-removing and desulfurization use is a wet dedusting desulfurization.The basic process of wet dedusting desulfurization is to use desulfurizing agent solution washing flue gas in desulfurization reaction tower, makes both that strong chemical reaction take place, and removes dust in flue gas and sulfide, reaches the purpose that purifies flue gas.
Existing Industrial Boiler wet dust removal desulfurizer can be divided into two big classes, a class split type wet dust removal desulfurizer that to be dedusting separate with desulfurization; Another kind of is the integral type wet dust removal desulfurizer that dedusting and desulfurization combine.
Split type wet dust removal desulfurizer has two kinds, and a kind of is that the whirlwind multi-tube dust cleaner increases spray expansion chamber doctor treatment, and another kind is that multi-tube dust cleaner increases the spray chamber doctor treatment.
The whirlwind multi-tube dust cleaner increases water-bath expansion chamber doctor treatment, boiler smoke at first enters multi-tube dust cleaner and carries out dry dust removal, send into the desulfurization of water-bath expansion chamber through the flue gas behind the one-time dedusting by air-introduced machine, flue gas enters chimney behind water bath desulfurization in the water-bath expansion chamber, its shortcoming is: floor space is big, need enough places to arrange expansion chamber, water level control simultaneously is difficult, resistance is too big when water level is high, cause the boiler operation under positive pressure, when water level is low, cause the invalid or desulfurized effect of desulfurization can not reach higher standard; Multi-tube dust cleaner increases the spray type desulphurization method and is meant, the flue gas of boiler is earlier through multi-tube dust cleaner, flue gas after the dedusting enters devulcanizer through flue, flue gas in devulcanizer desulfurization after air-introduced machine enters chimney, its shortcoming is that floor space is big, it is many that multi-tube dust cleaner adds desulfurizer rear pass elbow, the resistance of ducting is big, need to increase air-introduced machine power, to move towards consistent flue gas with water serious because of desulfurization water injector and flue gas, corrosion air-introduced machine and chimney, and the sticky particles in the flue gas is bonded in the hard attachment of formation on the draught fan impeller, cause the impeller disequilibrium, normally operation chronically continuously.
Existing integral type wet dust removal desulfurizer is, dedusting and desulfurization are carried out in same container, and desulfurization water and dirt are discharged from sewage draining exit simultaneously.The integral type wet dust removal desulfurizer can divide two big classes, one class is common gallet water curtain dust collector, this deduster floor space is bigger, installation period is long, after the deduster desulfurization, the flue gas moisture content is difficult to control, and overflow water causes secondary pollution easily, and the sedimentation basin floor space is big and need be equipped with the dirty equipment that drags for; Another kind of is the wet dust removal desulfurizer of steel, its shortcoming is that sulfide in the flue gas and desulfurizing agent react that a small amount of sulfuric acid of generating or the dust-laden particle in sulfurous acid and sulfate or sulphite and the flue gas are big to the corrosivity of steel, service time short, and the draining floor space is big.Desulfurization water once uses (the also reusable edible that has), and overflow water easily causes secondary pollution, and the pH value of desulfurization water is difficult to regulate, by the blowdown of artificial interruption, the operational effect fluctuations is big, can not stablize to reach desulfurized effect, and smoke discharging is moisture, can corrode air-introduced machine and flue.
Therefore, existing wet dust removal desulfurizer still exists, dust-removal and desulfurizing effect problem of unstable big to the burn into of deduster housing and air-introduced machine and floor space.
The utility model content
The purpose of this utility model is to provide a kind of wet dust removal desulfurizer, and it has solved in the background technology deduster housing seriously corroded, and floor space is big, water consumption big, dust-removal and desulfurizing effect problem of unstable.
Technical solution of the present utility model is:
A kind of wet dust removal desulfurizer, comprise dirt pocket 2 and air-water separation chamber 14, the top of described dirt pocket 2 is provided with smoke inlet 7 and spray equipment 1, the top of described air-water separation chamber 14 is provided with clean gas outlet 15, described dirt pocket 2 is communicated with air-water separation chamber (5) by the dirt pocket exhanst gas outlet 13 of bottom, the bottom of described dirt pocket 2 and air-water separation chamber 14 is provided with ash-pit 6
Its special character is:
Also be provided with eddy flow gas and water separator 4 in the described air-water separation chamber 14;
Described gas and water separator 4 comprises a blade bracing frame 9, and described blade bracing frame 9 comprises pillar 10 and blade 11, and described blade 11 is oblique plate;
Described oblique plate is connected with pillar 10 along same direction is oblique, constitutes the umbrella dentation.
Air-flow bounces oblique plate, and the umbrella dentalation can form eddy flow to air-flow again simultaneously, can get rid of most water simultaneously, reaches the purpose of gas-water separation.Gas and water separator 4 can be fixedly connected with being connected of air-water separation chamber 14 inwalls, can directly be welded on the inwall of air-water separation chamber 14; Also can flexibly connect, a movable adjusting screw(rod), the angle that can regulate gas and water separator 4 can be set in the junction of gas and water separator 4 and air-water separation chamber 14 inwalls.General spray equipment 1 should be arranged on the top of smoke inlet 7, because when being arranged on the below, and the space of spray equipment 1 top, because the flue gas admission velocity is fast, and the spray process is relatively slow, and the pressure of spray equipment 1 superjacent air space is increased, and spraying effect like this can be relatively poor; In addition, before flue gas was not handled, the dust-laden particle in the flue gas can cause damage to spray equipment 1.In order to make dust removing effects better, so below advancing mouth, nozzle, spray are set.
Above-mentioned dirt pocket exhanst gas outlet 13 places are provided with water fender 5, these water fender 5 downward oblique settings.For making the better effects if of dash dehydration, can be symmetrical set two water fenders 5 at dirt pocket exhanst gas outlet 13 places.
The bottom of above-mentioned dirt pocket 2 is provided with gap 3.
The inner surface of above-mentioned dirt pocket 2 and air-water separation chamber 14 is provided with corrosion-proof lining 12.
