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. 1,3, the utility model comprises upper shell 3 and the lower shell 2 that is interconnected, the bottom of lower shell 2 offers sewage draining exit 4, be provided with dismounting disc type cyclone 5 in the lower shell 2, on disc type cyclone 5, offer air inlet 1 and tedge air outlet 14 on the sidewall of the lower shell 2 of following both sides respectively, on the upper shell 3, the lower end offers the outlet 8 of air outlet 15 and cone structure respectively, lower shell 2 is connected with tedge 6 through tedge air outlet 14, air inlet 1, tedge 6 is connected with lower shell 2 tangent lines respectively, and be provided with blower fan 7 in the upper end of tedge 6, be provided with nozzle 13 in the porch of blower fan 7, the outlet of blower fan 7 is connected with upper shell 3 tangent lines.Blower fan 7 of the present utility model is provided with eight prismatic blade impellers, and the casing air inlet is that taper and blade shape coincide, and the blade breadth length ratio is 1: 1.5-1: 1, and the blade quantity of detachable disc type eddy flow plate 5 is 12-32, blade angle 25-60 degree.
Operation principle:
First cleansing phase: dust laden air enters from air inlet 1 tangent line of lower shell 2, and mixes with the dirty mud of upper shell 3, and under centrifugal action, part is thrown to the barrel of lower shell 2 more greatly by the grit of humidification, follows slurry to be collected and from sewage draining exit 4 discharges.Dust-contained airflow continues to flow through disc type cyclone 5, because the guiding of blade rotates air-flow and the change direction, grit mixes with mud once more and pounced on and catches the back discharge.The disc type cyclone improves to pounce on and catches efficient because no central tube is effectively controlled the air-flow vertical lifting, reduces the pressure loss.
Main cleansing phase: the dust-contained airflow behind the humidification enters tedge 6 by lower shell 2, in blower fan 7 porch, is provided with nozzle 13 to the suction inlet water spray, and dusty gas is fully mixed with atomized water, pours blower fan in the lump into.Under the effect of impeller of high-speed fan, water smoke and dust sharp impacts, cohesion make dust be pounced on by water and catch, and clean gas and mud tangentially enter upper shell 3 from the blower fan outlet.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 upper shell 3 by tangent line, because centrifugal force and reduction ascending air speed make mud separated from the gas, mud drains into lower shell from the outlet 8 of cone structure.Only purified gas drains into atmosphere from the upper shell outlet.
When being used for desulfurization, select the structure of embodiment 2 for use.The oar liquid of discharging from upper shell enters by pipeline regurgitates membrane pump, again slurries is squeezed into lower shell, through nozzle slurries is sprayed onto the eddy flow plate.Because the utilization again of desulfurizing agent has improved desulfuration efficiency, reduce the consumption of desulfurizing agent.
Blower fan of the present utility model: be provided with 8 prismatic blade impellers, wide type casing, casing axle one side is taper, 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; Air inlet is provided with spray nozzle; The blower fan type of belt drive is that direct connection, belt pulley connect, shaft coupling connects; Air inlet is single air intake and two air intakes.Blower fan adopts 8 blades and rational breadth length ratio that the technical performance of blower fan is guaranteed.Be designed to taper at fan casing in axle one side, coincide, reduce the slit between blade and the casing, effectively reduce bias current, turn-up loss, improve the air efficient of blower fan with blade shape.The blower fan arbor wheel is connected for expansion set with axle; The blower fan belt pulley is that tapered sleeve is connected with motor pulley, makes dismounting impeller and belt pulley more convenient, more laborsaving.
Detachable disc type eddy flow plate: easy for installation, the efficiency of dust collection height, the pressure loss is little.
Electric diaphragm pump is applicable to various strong acid, highly basic, deep-etching liquid, can carry≤150 ℃ of liquid, and the oar body of particle below 10mm all can pass through smoothly.The tube inner nozzle is a block-resistant type, and system is normal with assurance
First kind of structure of the present utility model both embodiment 1 is 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.Second kind of structure of the present utility model both embodiment 2 is the formula of regurgitating, and is used for 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 SX
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
(rotation speed of fan slightly improves) makes blower fan volume usefulness improve 17.6%, and blower fan structure is compacter, and material consumption reduces, and makes the blower fan total pressure efficiency improve 5-8% than SX simultaneously; The improvement of casing geometry.SX casing biside plate is dull and stereotyped, and air inlet is a cylinder.Because blade is trapezoidal, in axle one side, casing and blade form big space, produce effluent, refluence, have reduced fan efficiency.The utility model changes the casing air inlet into taper and blade shape coincide, and reduces the slit to greatest extent, has reduced the blower fan internal losses, has improved efficient.Change cylinder into cone at air inlet, change the angle of attack, improved fan efficiency.SX 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.SX adopts conventional cyclone, central tube is arranged, fixed.The utility model adopts the disc type cyclone, does not have central tube, and blade and prototype dish directly weld, and demonstrates higher efficient in similarly dehydration, absorption, dedusting.And be designed to detachable type, be convenient to install, overhaul.Be used for sulfur removal technology, the utility model adopts membrane pump to regurgitate device.
