Description
The utility model relates to a kind of device for eliminating smoke and dust, particularly a kind of device for eliminating smoke and dust that blower fan and dust removal installation are united two into one.
In dust smoke and extraction system in the past, blower fan is as just the driver part of a dust, and smoke abatement and dust control is by other independence facility, finish as filter, spray column, therefore the windage of system is bigger, this must improve the blast and the supporting power of blower fan, increases power consumption and investment, and operating cost is also higher.In addition, its shared place is also more.
The purpose of this utility model provides that a kind of place that takies is less, power consumption and the lower device for eliminating smoke and dust of operation cost.
Realize that solution of the present utility model is: the device for eliminating smoke and dust that is provided has a vertical air duct, the lower port of air duct is the dust import, upper port is a floss hole, below this air duct, be provided with a blower fan, the inwall of air duct is provided with many group helicla flutes, enlarges gradually from top to bottom along diameter in the spiral fluted, constitutes the diffuser of blower fan, vertically be provided with many group pressure water nozzles at the center of blower fan diffuser, be provided with annular collecting tank and discharge opening in the lower end of air duct.Ash-laden gas is sucked by blower fan by the air duct lower port, discharges from upper port.Because the rotation of draught fan impeller, and the spiral fluted effect on the air duct inwall, the ash-laden gas spiral rises, and passes the water smoke district that diffuser is formed by nozzle.Grit in the flue gas in uphill process because action of centrifugal force, also can be to peripheric movement, the water droplet in water smoke district also can make progress, to peripheric movement, both are stirred at the volley, absorption mutually, and it is dirty along helicla flute, to collecting tank after discharge opening discharge, thereby reach the purpose of " cleaning " flue gas.
The helicla flute of above-mentioned blower fan diffuser also can be made of many groups spiral flow deflector.
Compared with prior art, have spiral groove and a plurality of structure of nozzle form in this diffuser of the present utility model, make long-pending increase of wetted surface in the diffuser, the multilayer water smoke district that forms because of a plurality of nozzles also, grit to flue gas has good capture ability and multistage cleaning action, makes fume emission reach environmental protection standard.This device for eliminating smoke and dust can solve the smoke abatement and dust control problem with less power consumption and investment, takes up an area of less, operation cost is low, for user's acceptance, helps popularizing of efforts at environmental protection easily.
Below in conjunction with accompanying drawing content of the present utility model is described in detail.
Fig. 1 is the structure diagram of an embodiment of the utility model.
Fig. 2 is the partial enlarged drawing of Fig. 1 blower fan part.
Fig. 3 is the structure chart of another embodiment of the utility model.
As shown in Figure 1 and Figure 2: vertically the lower port 11 of air duct 1 is the dust import, upper port 12 is a floss hole, bottom in this air duct is provided with an axial flow blower 2, the inwall of air duct is provided with many group helicla flutes 13, enlarge gradually from top to bottom along diameter 14 in the spiral fluted, constitute the diffuser of blower fan.Helicla flute 13 can be deep-slotted chip breaker, shown in Fig. 1 left-hand component; Also can be the spiral flow deflector 16 shown in Fig. 1 right-hand component constitutes.These spiral grooves are different from the stator of eliminating turbulent flow in traditional air feed system, and it and spiralling air-flow rotate layout in the same way, do not increase windage.The inside edge line of spiral grooves is equivalent to the diffusion angle of traditional diffuser.At the center of blower fan diffuser along hard Nogata to being provided with three groups of pressure water nozzles 15, be provided with ring-like collecting tank 3 and discharge opening 4 in the lower end of air duct.
The motor of above-mentioned axial flow blower places in the protection tube 20 of an isolation dust and water smoke; there is the breather pipe 21 that communicates with ambient atmosphere at the top sealing of this protection tube 20, awl tail place; the wheel rim 23 groove sockets of protection tube lower end and draught fan impeller 22, fair water cone 24 affixed on the wheel rim 23 is provided with exhaust outlet 25.This axial flow blower that waterproof and heat-insulating protection is arranged has matching effect preferably with the spraying and dedusting diffuser on its top, and compact conformation is distinguished and admirable smooth and easy, dedusting more completely under the situation of less increase windage.
The impeller 22 of above-mentioned axial flow blower 2 is made up of primary blades 26, wheel rim 23, fan blade type disc 27, wheel hub 28, ring baffle 29 and fair water cone 24; Wherein the affixed ring baffle 29 of the upper limb of fan blade type disc 27 forms the outer ebb interval 31 of crossing between the periphery of ring baffle 29 and wheel rim 23 inwalls, crosses ebb interval 32 in forming between the interior week of ring baffle and hub surface, and fair water cone is provided with exhaust outlet 25.During impeller 22 rotations, when primary blades 26 drives flue gas, the fan blade type disc 27 of wheel rim 23 also drives the air motion in breather pipe 21 enters the protection tube, under the effect of wall attachment effect and ring baffle 29, air-flow divides two-way to flow out downwards: the one road attaches motor fuselage and drive end bearing bracket, the interior ebb interval 32 of crossing between interior week of the ring baffle of flowing through and hub surface, cooling motor and the drive end bearing bracket that the heavier fore bearing of load is housed; Another road attaches protection tube 20 inwalls, and the outer overcurrent between the periphery of the ring baffle of flowing through and wheel rim inwall is taken away the heat that hot flue gas passes to the protection tube to crack 31.The two-way air-flow all exhaust outlet on fair water cone 24 flows out, and imports in the flue gas.Because protection tube upper end closed, lower ending opening utilizes the ambient atmosphere cooling, and motor is operated in the ecotopia.
During this device for eliminating smoke and dust work, inevitably some water is dirty along blower fan tube inwall.For this reason, be provided with an annular that is positioned at below primary blades 26 surfacess of revolution slit 34 that leaks on the blower fan tube 33, it is formed with the 36 groove sockets of blower fan tube lower end by the inwall 35 of annular collecting tank 3.Along the dirty water of blower fan tube inwall, flow into collecting tank 3 through this slit 34 that leaks.
This device for eliminating smoke and dust also can adopt centrifugal blower, as shown in Figure 3.Centrifugal blower 5 places air duct 1 bottom, blower fan discharge pipe 51 insert air ducts 1 and with the 54 groove sockets of diffuser lower end, form the annular slit 55 that leaks, can avoid water to flow into blower fan.
No matter be to adopt axial flow blower or centrifugal blower, be equipped with the annular slit that leaks in the utility model, the shower water blower fan that also can not bleed.After containing the shower water remittance collecting tank of grit, flow out, after precipitation, neutralization, also can be recycled from discharge opening.
