Abstract
The water for dust removal has the disadvantages of unideal effect and high cost which can be known by heavy smoke in America power plants, starch paste liquid used for starch paste liquid for is not reported, smoke dust sticking and capturing capability is hundred times stronger than that of water, the starch paste liquid is 0.04 yuan / kg. By use of the method and device using the starch paste liquid for 100% elimination of boiler smoke dust to save water for dust removal, the smoke dust enters in from the bottom of a double overflow bubble tower, and is discharged from the top of the tower, the starch paste liquid enters in from the top of the tower, and is discharged from the bottom of the tower. When the smoke dust rises, the starch paste liquid is blown into liquid bubbles, the starch paste liquid rolls in the bubbles to impact the bubbles for sticking and removing. In the tower, 1000000 to 8000000 / M<3> starch paste liquid bubbles are produced and broken simultaneously, waste gas is packaged and released, the smoke dust impacts the bubbles for millions and millions times to ensure 100% sticking and capturing of the smoke dust entering into the tower, a large tower can load over thousand tons of the starch paste liquid to remove smoke dust in a large power plant; starch paste liquid filtration water is sent back to the tower, and filter residue is used as a fuel, so that water for dust removal and waste water treating cost can be saved completely, a manufacturer almost spend no money, and the elimination of the smoke dust removal can be performed without resistance.
Description
At present, boiler waste gas takes trickle dedusting, but effect is unsatisfactory, looks at that the cigarette dragon in power plant of U.S. overhead is just clear; Using water dedusting, except consuming a large amount of water rate, also wanting substantial contribution to dispose of sewage, so dedusting resistance is large.
Gelatinized corn starch liquid glues strong hundred times, the energy force rate water of catching flue dust; Starch per jin can obtain hundred jin of gelatinized corn starch liquid, its close prices zero.
At present, the report eliminating boiler smoke with gelatinized corn starch liquid is had no.What this technology proposed eliminates with gelatinized corn starch liquid 100% method and the device thereof that boiler smoke saves water for dust removal, is called for short this method and device thereof, can helps to solve the problem.
Eliminate with gelatinized corn starch liquid 100% method and the device thereof that boiler smoke saves water for dust removal, its beneficial effect is: save water for dust removal and pollution treatment water rate use completely, make producer significantly reduce costs.
Eliminate boiler smoke with gelatinized corn starch liquid 100% and save the method for water for dust removal and device thereof, the technical scheme that its technical solution problem adopts is, catches flue dust with gelatinized corn starch liquid is sticky, use again after filtering containing flue dust gelatinized corn starch liquid, and filter residue makes fuel; Boiler waste gas (1) is sent into the compound overflow foaming tower (3) that gelatinized corn starch liquid is housed by it with blower fan (2), with pump (4) by compound overflow foaming tower containing flue dust gelatinized corn starch liquid, send filtering tank (5) to filter, gelatinized corn starch liquid is sent to compound overflow foaming tower with pump (6), filter residue is used as fuel, thus the method using gelatinized corn starch liquid 100% to eliminate boiler smoke saving water for dust removal is able to normal operation.As Fig. 1
Dust-removing waste gas is sent into and is equipped with in the compound overflow foaming tower of gelatinized corn starch liquid by blower fan again, when waste gas passes the porous plate of compound overflow foaming tower, gelatinized corn starch liquid on porous plate is blown out froth bed, and the flue dust of waste gas clashes into gelatinized corn starch vacuole foam, is glued catch by gelatinized corn starch liquid foam film.In compound overflow foaming tower, every cubic metre has 100 ten thousand to 800 ten thousand foams to be wrapped up by waste gas, and makes waste gas roll in paste vacuole, is caught when making flue dust clash into gelatinized corn starch liquid foam film by sticky.The large manyfold of viscosity ratio water of gelatinized corn starch liquid, so gelatinized corn starch liquid catches effect to the sticky of flue dust, manyfold larger than water.Filter residue is used as fuel, without water, saves pollution treatment water rate and uses; Starch per jin can obtain hundred jin of gelatinized corn starch liquid, therefore, with the smoke abatement and dust control of this technology, substantially need not change money.
Be described further by the following examples.
Compound overflow foaming tower is the device that execution gelatinized corn starch liquid 100% eliminates that boiler smoke saves the method for water for dust removal.
Compound overflow foaming tower, its beneficial effect is: flue dust all can be removed, and saves pollution treatment water rate use, makes smoke abatement and dust control that resistance can not had to carry out.
Compound overflow foaming tower, the technical scheme that its technical solution problem adopts is, by bassoon (7), the porous plate (8) of uniform aperture, overflow pipe (9), turnover gas-liquid pipe (10) composition; Its installation is, close bassoon one end, a segment distance of being respectively separated by by polylith porous plate, is arranged in bassoon; Install many overflow pipes in bassoon, every bar overflow pipe is through polylith porous plate; Every bar overflow pipe upper end is near the most much higher orifice plate, and overflow pipe lower end, near minimum porous plate, is closed the bassoon other end, is installed into out gas-liquid pipe, becomes compound overflow foaming tower (11) at closed bassoon upper and lower side; Thus make compound overflow foaming tower be able to normal operation.As Fig. 1
Existing combination principle is introduced compound overflow foaming tower and is run:
Exhaust gas and smoke enters at the bottom of tower, discharges from tower top; Gelatinized corn starch liquid enters from tower top, discharges at the bottom of tower.The waste gas that gelatinized corn starch liquid is through porous plate blows out gelatinized corn starch vacuole, when gelatinized corn starch vacuole floor height crosses overflow pipe, gelatinized corn starch vacuole flows into the porous plate of lower floor from the overflow mouth of pipe, becoming gelatinized corn starch liquid stays on this porous plate, the waste gas being through again this porous plate blows out gelatinized corn starch vacuole layer, gelatinized corn starch vacuole flows into the porous plate of a lower floor from the overflow mouth of pipe again, and gelatinized corn starch liquid repeatedly successively flows down, until gone out by tower bottom flow from multiple.Control gelatinized corn starch flow quantity, make a small amount of gelatinized corn starch vacuole from the porous plate of one deck the inflow of the overflow mouth of pipe; Control gas flow, the gelatinized corn starch vacuole layer of three plate porous plates under tower top is kept, and gelatinized corn starch liquid is former enters concentration, so when the preceding three beats porous plate close to tower top, the flue dust in waste gas is all by gelatinized corn starch liquid sticky removing.
In compound overflow foaming tower every cubic metre, waste gas wraps up by 100 ten thousand to 800 ten thousand the gelatinized corn starch vacuole foams that can produce simultaneously and break, and makes flue dust roll in gelatinized corn starch liquid vacuole.1,100 blocks of porous plates can be had in compound overflow foaming tower, gelatinized corn starch liquid can be filled and surpass kiloton, all removing high-power station flue dust; Overflow pipe makes the most foams of every layer of foam touring tens times of this layer of froth bed, makes the flue dust thousands of times of every layer clash into gelatinized corn starch liquid; In tower, flue dust clashes into the gelatinized corn starch liquid of strong hundred times, viscosity ratio water for ten million time, ensures that the flue dust entered in tower is glued by 100% and catches.
