Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment:
With reference to Fig. 1-2, this specific embodiment is by the following technical solutions: it is by base plate 1, centrifugal blower 2, first airduct 3, drainpipe 4, Venturi tube 5, cyclone separator 6, the cyclic water tank device 7 and second airduct 8 are formed, base plate 1 is provided with centrifugal blower 2, centrifugal blower 2 links to each other with first airduct 3, first airduct 3 links to each other with Venturi tube 5, Venturi tube 5 links to each other with second airduct 8, second airduct 8 links to each other with cyclone separator 6, cyclic water tank device 7 links to each other with the bottom of cyclone separator 6, first airduct 3 links to each other with cyclic water tank device 7 by drainpipe 4, and the water injector in the Venturi tube 5 links to each other with cyclic water tank device 7 with valve by pipe.
Described first airduct 3 comprises the first access hole 3-1 and water fender 3-2, and the first access hole 3-1 is arranged on the afterbody top of first airduct 3, and water fender 3-2 is arranged on the afterbody below inwall of first airduct 3.
Described Venturi tube 5 comprises collapsible tube 5-1, trunnion 5-2 and convergent divergent channel 5-3, and the end of collapsible tube 5-1 links to each other with first airduct 3, and the other end links to each other with trunnion 5-2, and trunnion 5-2 links to each other with convergent divergent channel 5-3, and convergent divergent channel 5-3 links to each other with second airduct 8.
Described cyclone separator 6 comprises central tube 6-1, bypass pipe 6-2 and detects hole 6-3, the arranged outside of cyclone separator 6 has bypass pipe 6-2, central tube 6-1 vertically is vertically set on cyclone separator 6 inside center positions, and central tube 6-1 is provided with and detects hole 6-3.
Described cyclic water tank device 7 comprises fixed support 7-1, water circulating pump 7-2 and rainhat 7-3, fixed support 7-1 is provided with water circulating pump 7-2, water circulating pump 7-2 is provided with rainhat 7-3, and water circulating pump 7-2 links to each other with cyclic water tank device 7 and Venturi tube 5 with valve by pipe.
Described second airduct 8 is provided with the second access hole 8-1, and the water injector in second airduct 8 links to each other with cyclic water tank device 7 with valve by pipe.
Venturi tube 5 in this specific embodiment is to allow between the gas of entrained solids particle and the wash liquid a bigger speed difference be arranged, and allows the particle energy improve, and overcomes hydrophobicity, can throw in the liquid; The latter rotates gas in the moistening cylindrical cavity of periphery, secondary flow many times makes the gas-liquid contact-making surface upgrade with high speed, catches the solid particle that does not enter in the water, and gas-liquid separation under strong centrifugal action, gas rises from central tube at last, outside pipeline is discharged tower; Dusty gas enters first airduct 3 under the strong promotion of centrifugal blower 2, gas speed increases suddenly to more than the 50m/s when collapsible tube 5-3, and this strand high velocity air impacts from the recirculated water of water injector (nozzle) ejection and makes it atomizing, and this promptly is the foam process.Speed was the highest when air-flow reached trunnion 5-4, when high velocity air and drip group clamp-on trunnion 5-4, gas-liquid two-phase fully collides contact, harmful substance in the drop cohesion waste gas, this promptly is a coacervation process, at this, again because gas-liquid has a speed difference, this speed difference is smashed drop and is torn, and has strengthened gas-liquid contact area and flocculating result widely, and this powerful active force makes that the hydrophobicity of harmful components is overcome fully in the waste gas.The pollutant that can be dissolved in liquid also enters among the drop.At convergent divergent channel 5-1, air-flow gradually falls, and static pressure obtains certain recovery, and when incision second airduct 8, speed is reduced to the required speed that enters cyclone separator 6.
Owing to carry a large amount of liquid secretly in the gas, inner surface at cyclone separator 6 forms the complete liquid film of one deck, tangent line and the gas-liquid of going into are descended along spiral inner wall, liquid is then owing to the severe relation is got rid of on inwall, each particle of air-flow is near inwall during helical flow, be not that curve flows, but refraction is flowed many times, be infinite a plurality of " secondary flow " this just make each particle in the gas that the chance that contacts repeatedly with the inwall liquid film is all arranged, be that each solid particle and DDGS all are unable to escape the result who " is caught " by liquid, like this, remove efficient also just inevitable more than 99.8%, separated gas that must be cleaner, the atmosphere that enters up to standard from central tube 6-1 at last.
The advantage of this specific embodiment is: its can improve exhaust-gas treatment economical, stable, efficiently, reduces significantly than conventional process plant area area and weight of equipment and size; Prevent the obstruction of solid particulate matter in the waste gas (comprising the organic class particle that freezes) effectively, thereby reduce the operation cost of factory significantly packing layer or filtration (cloth) layer; The design optimization of central tube gas flow, more help the rotation of gas-liquid-solid three-phase mixture, thereby improve separative efficiency.
