Abstract
The utility model relates to a venturi desulfurizing duster comprising a venturi duster which is composed of an air inlet, a collapsible tube, a throat tube, a divergent tube, a fume outlet and a shell body. The utility model is characterized in that a conical diffuser is arranged in the center of the divergent tube. Gas and liquid are fully mixed and moistened by high pressure water which is sprayed from a nozzle at the point of the collapsible tube through the throat tube. Then, the gas and the liquid uniformly and quickly impact the surface of water which is arranged in a dust hopper through the diffuser. Therefore, an impact type duster is formed between the dust hopper and the venturi divergent tube. The impacting water level is controlled by an overflow device which is connected with a circulating pump and a circulating water channel through a pipeline. Fume which is impacted and turned back is exhausted from the fume outlet through a gas and water separating chamber, a dehydrator and an exhausting chamber.
Description
The utility model relates to a kind of Venturi tube desulfurizing dust-collector, and this deduster is on venturi granite water dust scrubber architecture basics, the novel gas cleaning desulphurization plant that develops.
Existing hydrofilter kind is more, as gravitational precipitator, cyclone dust collectors, self-excitation aerosolater, bubble dust collector, venturi scrubber, mechanical induction deduster etc.With the venturi granite water dust scrubber is example, once is widely used in the gas cleaning of stove as far back as early eighties, and effect is apparent in view.But because the volume of this dust separation system is too huge, so it is also big to take effective land use area.And also there are many incomplete places in this deduster: [1] water consumption is too big, is several times or tens times of general wet scrubber, and not only the national conditions that lack with China water resource are incompatible, and is a kind of significant wastage to water resource.[2] do not have complete dewater unit,, add fume-dehydrating, dry undesirable again, therefore produce the fan belt water phenomenon, make flue and blower fan that serious acid corrosion take place, reduce service life of equipment greatly because aqueous vapor is excessive.[3] owing in the sedimentation basin a large amount of mud oars are arranged, sewage is assembled, and draws as machinery and digs device fails or during because of mismanagement, all can cause sewage pollution, and operating cost is very big, so this deduster is tending towards superseded substantially in recent years.
The purpose of this utility model is to provide a kind of Venturi tube desulfurizing dust-collector, and this deduster collection smoke elimination, dedusting, desulfurization are one, have higher utility.
The utility model above-mentioned purpose is finished like this.
A kind of Venturi tube desulfurizing dust-collector, this dirt device comprises the venturi scrubber of being made up of air inlet, collapsible tube, trunnion, increaser, exhanst gas outlet and housing thereof, is primarily characterized in that the outlet of increaser and corresponding section, dust hopper top are provided with a tapered air diffuser.Water under high pressure by the ejection of collapsible tube place nozzle, when trunnion with the flue gas behind fully mixing of gas-liquid two-phase, humidification, the coalescence, the water surface of evenly setting in dust hopper hastily through air diffuser impacts, thereby make between dust hopper and Wen's the increaser and constituted a very good impingement dust collector, impact water level and control, be connected with circulating water chennel with circulating pump by pipeline by overflow device.The flue gas that turns back after the impact by exhaust chamber, is emitted by exhanst gas outlet at last through air-water separation chamber and dehydrator.Above-mentioned housing can be designed to square or circular, and exhanst gas outlet can design at dust remover roof as required.
Venturi tube desulfurizing dust-collector provided by the utility model has that compact conformation, floor space are little, desulfurization and dedusting can finish simultaneously, advantage such as cost hangs down small investment, water saving is pollution-free, operating cost is low, simple to operate, easy to maintenance.Main feature is:
1. the elite part with the Venturi tube dedusting organically combines with the lector principle, makes ash-laden gas carry out double purification fully effectively, makes desulfurization and efficiency of dust collection obtain more significantly improving.
2. with the space of gas-water separation speed, reduce to the high best point of air water stripping, solved wet scrubber because of fan belt water, and made the difficult problem of blower fan and flue generation heavy corrosion, the service life of having improved equipment by effectively setting.
3. water consumption is controlled by overflow device, with the water that flows in the circulating water chennel, is recycled by the pipeline connection by water pump, has reached using water wisely, the purpose that cuts down the consumption of energy.
Because this deduster possesses above characteristics, it is hereby ensured this deduster, the special continuous efficient operation that constantly keeps in actual condition.Through testing the performance indications of this deduster, desulfuration efficiency＞75%; Efficiency of dust collection＞98%; The class area environmental requirement of GB13271-91 standard has been satisfied in lingemann blackness＜1 grade comprehensively.
Below in conjunction with accompanying drawing, introduce the utility model embodiment concrete structure and operation principle thereof in detail.
Fig. 1 is the utility model example structure schematic diagram.
In the present embodiment, increaser 13, air diffuser 2 and dust hopper 1 are assembled in up and down in the same housing 11, and venturi scrubber that interdependence constitutes and impingement dust collector are formed the secondary wet scrubber.Through collapsible tube 7, by trunnion 4, the water under high pressure that nozzle 6 sprays into (desulfurization alkali lye) is atomized fast, and gas-liquid two-phase is fully mixed at a high speed by air inlet 10 for above-mentioned Venturi tube desulfurizing dust-collector, flue gas.The center line of above-mentioned tapered air diffuser 2 is fixed on the increaser 13 exit center lines, when air-flow process increaser 13, is poured in dust hopper 1 water by air diffuser 2 even shuntings.The grit that is captured removes quarrel machine 3 by the bottom and discharges through post precipitation.Be provided with annular dehydrator 5 between trunnion 4 outsides and the housing 11, housing 11 inner chambers are divided into air-water separation chamber 14 and exhaust chamber 9.Flue gas through double purification rises slowly at air-water separation chamber 14, passes through dehydrator 5, exhaust chamber 9, enters atmosphere by gas outlet 8.
Water level in the dust hopper 1, by overflow device 15 controls, the desulfurization alkaline stream, recycles by connecting line 12 supply nozzles 6 again by water pump 16 through the precipitation clarification to circulating water chennel 17.
