Abstract
The present invention relates to a wet type dedusting and fume-purifying device which uses purifying agents for generating a foam layer. The wet type dedusting and fume-purifying device is provided with a foam purifier, wherein an atomizer, an upper web plate and a lower web plate are arranged in a cylinder body of the foam purifier, a foam chamber is formed between the two web plates, a fume inlet and a fume outlet of the foam purifier are respectively arranged at the upper part and the lower part of the cylinder body, a dust outlet is arranged at the bottom of the cylinder body, the dust outlet is connected with a dust collector, a rotating shaft is arranged in the cylinder body and is connected with a main shaft of a motor which is arranged on the top of the cylinder body, and a position of the rotating shaft, which is in the foam chamber, is connected with blades which generate downward wind; a circulating water tank and a purifying agent tank are arranged beside the cylinder body of the foam purifier. When atomized water with the purifying agents passes through the upper web plate, air bubbles are generated, the foam chamber is filled with large and small air bubbles, the foam layer is relatively stable and even, dust in the fumes collides with inner surfaces and outer surfaces of the air bubbles and are captured by the surfaces of the air bubbles, gaseous pollutants in the fumes are absorbed by absorbents in the purifying agents, and the dust lowers to the dust collector following liquid drops formed by the broken foam.
Description
Technical field
The present invention relates to smoke eliminator.
Background technology
At present, the way of administering flue dust is a lot, respectively has different characteristics, wherein wet dust removal is a kind of more common administration way, and wet dust removal is to wash dusty gas with water, and liquid film, drop or the bubble that utilization forms caught the grit in the gas, grit is discharged with water, and gas is purified.Liquid film, drop or bubble be mainly by inertial collision, the diffusion of tiny grit, liquid film, drop make behind the grit humidification cohesion and to the adhesive attraction of grit, reach the purpose of catching grit in the waste gas.Bathing formula deduster in the wet scrubber comprises various ways such as wet dust collector, bubble dust collector, disintegrating scrubber, their operation principle is basic identical, all be to make dusty gas powerful by certain water layer, water has been dashed spray (or being foam), dusty gas is fully contacted with water, dust is drained with sewage after being absorbed (cohesion) by water.Disclosed deduster all is to belong to bubble dust collector to China Patent No. in disclosed deduster and China Patent No. in the utility model patent specification of " impacts-foam mechanical and hydraulic combined dust device " be called " sieve plate bubble dust collector " for " 902081594 " the utility model patent specification for " 882201441 " name is called.The advantage that though bubble dust collector has is simple in structure, cost is low, the froth bed instability has certain requirement to wind speed, do not reach requirement as wind speed, then be difficult for setting up froth bed, fall end purification efficiency, certainly wind speed can not be too big, otherwise can produce serious water phenomenon.
In addition because the structure of wet scrubber is inequality, so the effect difference that different dust sizes are handled.
Summary of the invention

Cleanser in the above-mentioned cleanser case is mainly mixed by surfactant, foam stabilizer, absorbent.
Roller end in the above-mentioned purifying tube is connected with bearing, bearing be installed in purify the bearing spider that cylindrical shell is connected in.
The position of the pipeline connection port of above-mentioned cyclic water tank is not less than the position of the pipeline connection port of disposal box.
Web plate in the middle of being provided with between two web plates in the above-mentioned purification cylindrical shell, web plate is separated into a chamber purifying inner barrel, middle two Room, is the foam chamber, respectively is provided with fan blade in the foam chamber.
Above-mentioned outlet flue is provided with inwardly downward-sloping web plate.
For realizing further purpose of the present invention, this smoke eliminator also has the spray centrifugal scrubber, advancing of scrubber, outlet flue is separately positioned on the following of cylindrical shell, top, slag notch is arranged on the bottom of cylindrical shell, slag notch connects slag trapping box, be provided with sprayer and rotating shaft in the dedusting cylindrical shell, rotating shaft is connected with the main shaft of the motor that is in the cylindrical shell outside, connect the fan blade of the wind-force of generation to some extent in the rotating shaft towards Way out, the side of cleaning dust cylindrical shell is provided with the washing water tank, the connecting pipe of washing water tank and sprayer is provided with water pump, the top of slag-storing box is connected by pipeline between the water tank with washing, and the outlet flue of scrubber is connected with the mouth that advances of foam purifying device.
Roller end in the above-mentioned scrubber cylindrical shell is connected with bearing, and bearing is installed in the bearing spider that is connected with the dedusting tube.
The position of the pipeline connection port of above-mentioned washing water tank is not less than the position of the pipeline connection port of slag trapping box.
This smoke eliminator also takes the outlet flue of scrubber to be connected by cooler with advancing between the mouth of foam purifying device, be provided with two dividing plates in the condenser chamber, it is that the smoke chamber centre is water cavity three parts that the inner chamber of cooler is separated into two ends, be provided with smoke pipe in the middle water cavity, smoke pipe is connected between two dividing plates and connects with the smoke chamber of both sides, the cooler side is provided with cooling water tank, and the water cavity two ends of cooler respectively are provided with the inlet tube and outlet tube that is connected with cooling water tank, are provided with water pump in water inlet pipe.
The present invention is a kind of purifier that uses cleanser that is applicable to, form foam device by sprayer, web plate, cyclic water tank and cleanser case, the atomized water that has a cleanser produces foam during by web plate, foam is full of the foam chamber, foam constantly breaks and constantly generates, froth bed is metastable, can not require to make froth bed to set up not because of wind speed reaches in this process.Smoke exhaust is when the foam chamber, because the particle in the smoke exhaust and the collision of foam caught by foam, the stirring of fan blade can promote the particle in the smoke exhaust and the collision of foam, accelerates to catch.There is the part smoke exhaust to be cut apart encirclement by foam, because the stirring of fan blade changes the foam movement velocity, make particle and foam interior surface in the smoke exhaust collide and be caught by foam interior surface, surrounded simultaneously and smoke exhaust still at large is separated with foam and broken up, promote smoke exhaust and foam to recombinate by foam.The stirring of fan blade promotes foam and travels forward, and reduces the resistance of motion, and under action of centrifugal force, foam shifts to the barrel direction, and the drop that the back of breaking forms is along dropping down to disposal box under the barrel.The stirring of fan blade can also make the gaseous contaminant in the smoke exhaust fully contact with absorbent when passing froth bed.The setting of fan can prevent to cause flue gas to pass through to influence purification from empty tube because of the foam skewness forms empty tube.So the foam purifying utensil has good clean-up effect.
The present invention is realizing that the technical scheme that further purpose is taked is to set up the spray centrifugal scrubber as first order dedusting, flue gas is after first order dedusting, removed bigger grit effectively, removed the part gaseous contaminant simultaneously, flue-gas temperature obtains cooling, behind subcooler, flue-gas temperature is further cooled off, help the foam existence of foam purifying device and alleviated the purification load of foam purifying device greatly, flue gas can reach very desirable clean-up effect through the purification of second level foam purifying device.
