Accompanying drawing explanation
Fig. 1 is the schematic diagram of this Multi-stage dust removing device that improve efficiency of dust collection of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described.
The of the present utility model this Multi-stage dust removing device that improve efficiency of dust collection as shown in Figure 1, it includes gravitational dust collecting device 1 and water-bath type dust arrester 2.Gravitational dust collecting device 1 is to adopt reduce suddenly air-flow velocity and change the mode flowed to so that the dust of larger particles is under the effect of gravity and inertia force, separated from the gas, therefore can remove the dust of larger particles in flue gas.Water-bath type dust arrester 2 catchments and bathes and spray two ways in one, it is possible to be greatly improved efficiency of dust collection.Described gravitational dust collecting device 1 connects an air inlet pipe 10, described air inlet pipe 10 is provided with an air-introduced machine 100, this air-introduced machine 100 can attract the flue gas produced in combustion furnace, and makes the negative pressure that in combustion furnace, maintenance is certain, and can overcome the pressure loss in flue or gravitational dust collecting device 1.It is provided with a dedusting chamber 11 in described gravitational dust collecting device 1, in described dedusting chamber 11, is provided with dividing plate 110, after flue gas enters dedusting chamber 11, through the stop of dividing plate 110, slow down flow velocity so that dust is separated from air-flow, reach the purpose of dedusting.Described gravitational dust collecting device 1 is connected with a deashing device 12, and the dust overstock in dedusting chamber 11 can be discharged by this deashing device 12, to ensure that gravitational dust collecting device 1 can continuous operation.Described gravitational dust collecting device 1 connects described water-bath type dust arrester 2 by a connection pipeline assembly 20, and the flue gas after gravitational dust collecting device 1 processes enters further dedusting in water-bath type dust arrester 2 by connecting pipeline assembly 20.Being provided with a dirt pocket 30 in described water-bath type dust arrester 2, this dirt pocket 30 can hold a large amount of flue gas.Described connection pipeline assembly 20 includes connecting tube 201 and Venturi tube 202, and this Venturi tube 202 is by changing flue gas stream flow velocity so that the dust in flue gas is absorbed by better fog, thus reaching the purpose of dedusting.Described Venturi tube 202 is placed in described dirt pocket 30, and this Venturi tube 202 is placed on the centrage of dirt pocket 30.Described Venturi tube 202 is sequentially provided with inlet cylinders section 220, circular cone contraction section 221, cylinder trunnion section 222 and circular cone diffuser 223, inlet cylinders section 220, circular cone contraction section 221, cylinder trunnion section 222 and circular cone diffuser 223 set gradually from top to bottom, circular cone contraction section 221 diameter from top to bottom is gradually reduced, circular cone diffuser 223 diameter from top to bottom is gradually increased, the diameter of cylinder trunnion section 222 is constant, but minimum.Therefore, air-flow first accelerates in Venturi tube 202, more slowly slows down, and so makes fog and dust be sufficiently mixed, thus reaching the purpose of gas, dirt separation.Described dirt pocket 30 is connected with a pond 300, described circular cone diffuser 223 lower end is near described pond 300, flue gas after Venturi tube 202 is accelerated enters in pond 300, temperature can be reduced, water smoke after gasification can absorb again the dust in flue gas simultaneously, deepens contact further so that dust increases due to weight, thus being left in pond 300, purify flue gas.Being provided with one first drainage screen 310 in described dirt pocket 30, this first drainage screen 310 can stop that dust-laden drop rises so that droplets fall back is to pond 300.Being additionally provided with a circulation sprayer unit 60 on described water-bath type dust arrester 2, this circulation sprayer unit 60 can produce water smoke, and eruption is in Venturi tube 202, so that dust is fully absorbed.Described water-bath type dust arrester 2 is connected above an exhaustor 40, and this exhaustor 40 connects dirt pocket 30 so that the flue gas of rising discharges dirt pocket 30.Described exhaustor 40 end connects a decompression exhaust device 50, this decompression exhaust device 50 can reducing smoke air-flow velocity, and can dedusting further.Described decompression exhaust device 50 includes housing 501 and the second drainage screen 502, and housing 501 cross section can be square.Being evenly distributed with venthole 510 on described housing 501, this venthole 510 is distributed on housing 501, it is possible to speed exhaust velocity.The sectional area of described housing 501 is more than the sectional area of described exhaustor 40, and when flue gas enters in housing 501 from exhaustor 40, space becomes suddenly big, it is possible to the flow velocity of reducing smoke significantly.
Wherein, described connecting tube 201 is perpendicular to described Venturi tube 202, so changes the flow direction of flue gas, and is conducive to merging with spraying, increases contact area.
A sludge outlet 301 it is provided with bottom described pond 300, after water-bath type dust arrester 2 employs a period of time, a large amount of mud can be overstock in pond 300, at this moment just can pass through sludge outlet 301 and overstocked mud is discharged so that water-bath type dust arrester 2 can be reused.
Described first drainage screen 310 is socketed in the end of described circular cone diffuser 223, and the lower surface of the first drainage screen 310 is concordant with the end face of circular cone diffuser 223.
Described circulation sprayer unit 60 includes suction valve 601, water pump 602, water-supply-pipe 603 and aerosol apparatus 604, and this suction valve 601 can reduce the inflow of foreign material, reduces the probability of blocking, and water can be become high-pressure water mist ejection by aerosol apparatus 604.Described suction valve 601 is placed in described pond 300, described suction valve 601 connects described water pump 602, described water pump 602 connects described water-supply-pipe 603, and described water-supply-pipe 603 is provided with some described aerosol apparatus 604, and described aerosol apparatus 604 is placed in described inlet cylinders section 220.Water pump 602 draws the water in pond 300 by suction valve 601, then passes through aerosol apparatus 604 and becomes water smoke ejection, then landing is back in pond 300, thus can recycle.
The mesh aperture of described second drainage screen 502 is less than the mesh aperture of described first drainage screen 310, and the second drainage screen 502 can filter more tiny dust, it is possible to remove the dust in flue gas further.So far, the present utility model purpose is accomplished.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
