The specific embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are described in further detail.
Embodiment 1, referring to Fig. 1, and 2, the bottom of the utility model cylindrical shell 1 offers sewage draining exit 4, and the top offers air outlet 5; Blower fan 2 is provided with air inlet 3, and the outlet of blower fan 2 is connected with cylindrical shell 1; Be provided with water inlet 6 in the porch of blower fan 2.The outlet of blower fan 2 is connected with cylindrical shell 1 tangent line.Blower fan 2 of the present utility model is provided with eight prismatic blade impellers, and the blade breadth length ratio is 1: 1.4-1: 1.1.
Operation principle:
First cleansing phase: flue gas enters from the air inlet 3 of blower fan 2, simultaneously being provided with nozzle in blower fan water inlet 6 sprays water to suction inlet, dusty gas is fully mixed in the spiral case of blower fan 2 with atomized water, under the effect of impeller of high-speed fan, water smoke and dust sharp impacts, cohesion, dust is pounced on by water caught, clean gas and mud tangentially enter cylindrical shell 1 from the outlet of blower fan 2.Tiny grit is pounced on the process of catching in the wet type blower fan, by following approach: 1, gas, liquid, the cohesion of grit turbulent mixture.2, grit collides on the rotation prismatic blade.3, because the power that the rotation of the high speed of impeller produces forces grit and the wet surperficial relative motion of casing.
Separation phase: purified gas and mud enter cylindrical shell 1 by tangent line, because centrifugal force and reduction ascending air speed make mud separated from the gas, mud is discharged cylindrical shells 1 from sewage draining exit 4.Discharge from the air outlet 5 of cylindrical shell 1 through purified gas.
When being used for desulfurization, the alkali lye that the water that will spray into from the water inlet 6 of blower fan 2 changes suitable concn into gets final product, because the strong agitation of draught fan impeller, acid-base neutralization reacting phase in the sweetening process is when abundant, therefore than traditional desulfurizing tower, this generator set desulfurization efficient greatly improves, and the desulfurizing agent use amount also significantly reduces.
Blower fan 2 of the present utility model: be provided with 8 prismatic blade impellers, wide type casing, reel is connected for expansion set with axle; Axle all is fixed on the frame with bearing and motor, and blower fan belt pulley, motor pulley are tapered sleeve and connect; The air inlet 3 of blower fan 2 is provided with spray nozzle; Blower fan 2 type of belt drive are that direct connection, belt pulley connect, shaft coupling connects; The air inlet 3 of blower fan 2 is single air intake.Blower fan 2 adopts 8 blades and rational breadth length ratio that the technical performance of blower fan 2 is guaranteed.The arbor wheel of blower fan 2 is connected for expansion set with axle; The belt pulley of blower fan 2 is that tapered sleeve is connected with motor pulley, makes dismounting impeller and belt pulley more convenient, more laborsaving.
The utility model can either be widely used in the dedusting of non-hydrophobicity dusty gas.Be specially adapted to high temperature, high humidity, big, the first dust content height of viscosity, place that dust granules is thin.As industries such as mine, metallurgy, chemical industry, generating, cement, papermaking, industry and civil boilers.Also can be widely used in dedusting, desulfurization, denitrogenation, defluorinate of industrial furnace flue gas etc.
The utility model adopts 8 prismatic blades, and this calculates the back to non newtonian law downstream motion analysis and determines.As being to impeller diameter
Blower fan, do not changing rotating speed, under power and the impeller shape situation, only the number of blade is changed into 8, its air quantity, blast have all improved, it is particularly evident that blast improves, computational analysis has shown the best of breed advantage of 8 blades and the defective of 6 blades.Computational analysis shows that reasonably breadth length ratio is particularly important to improving fan efficiency.The utility model is with former
Width of blade changes 260mm into by 220mm, and the number of blade is 8, and the blade breadth length ratio is 1: 1.1, is not changing under fan delivery, blast and the power of motor situation, and impeller diameter is reduced to
(blower fan 2 rotating speeds slightly improve) makes blower fan 2 volume usefulness improve 17.6%, blower fan 2 more compact structure, and material consumption reduces, and makes blower fan 2 total pressure efficiencies improve 5-8% than SXS simultaneously; SXS is provided with axle sleeve between reel and first bearing, in case in fact the impeller displacement does not have problems, but produce the another one defective, and promptly axle sleeve and bearing press closer, and cause bearing heating.After 20 minutes, bearing temperature promptly rises to 80 ℃, can not find reason for a long time in the empty wagons operation, and behind the cancellation axle sleeve, after 20 minutes, bearing temperature no longer raises about 30 ℃ in the empty wagons operation.
