The specific embodiment
Below, with reference to accompanying drawing, the present invention is more fully illustrated, shown in the drawings of exemplary embodiment of the present invention.But the present invention can be presented as multiple multi-form, and should not be construed as the exemplary embodiment that is confined to narrate here.But, these embodiment are provided, thereby make the present invention comprehensively with complete, and scope of the present invention is fully conveyed to those of ordinary skill in the art.
For ease of explanation, here can use such as " on ", the space relative terms such as D score " left side " " right side ", the relation for element shown in key diagram or feature with respect to another element or feature.It should be understood that except the orientation shown in figure, spatial terminology is intended to comprise the different azimuth of device in using or operating.For example, if the device in figure is squeezed, be stated as the element that is positioned at other elements or feature D score will be positioned at other elements or feature " on ".Therefore, exemplary term D score can comprise upper and lower orientation both.Device can otherwise be located (90-degree rotation or be positioned at other orientation), and the relative explanation in space used here can correspondingly be explained.
As shown in Figure 1 and Figure 2, the pneumatic capturing device that the present invention administers for catering trade flue gas PM2.5, comprises venturi scrubber 1, water bath 2, centrifugal moisture trap 14 and clean flue gas delivery line 17.
Wherein, venturi scrubber 1 is arranged on water bath 2, the top of venturi scrubber 1 is provided with water inlet 5 for injection, injection is with being provided with the nozzle 8 that produces storing injection power by supercharging on water inlet 5, in the upper portion side wall of venturi scrubber 1, be provided with several former smoke inlets 4, the outlet top of venturi scrubber 1 is provided with cyclone 7, the outlet of venturi scrubber 1 is provided with trumpet type outlet 9, and the outlet of venturi scrubber 1 is arranged at the set height position of the liquid level top of absorption liquid 3, and its spacing is 0.1～0.5 meter.
In water bath 2, be filled with a certain amount of absorption liquid 3, the bottom of water bath 2 is connected with water inlet 5 with injection by pipeline 10, and on pipeline 10, be provided with circulating pump 11, circulating pump 11 is transported to injection water inlet 5 by the absorption liquid in water bath 23 and recycles.On pipeline between circulating pump 11 and water bath 2, be provided with supplementing water entrance 12, the bottom of water bath 2 is also provided with outer drain outlet 13.
The top of water bath 2 is provided with clean flue gas delivery line 17, and centrifugal moisture trap 14 is installed on it.The air inlet place that clean flue gas delivery line 17 is positioned at water bath 2 is provided with trumpet type air inlet 18, and clean flue gas delivery line 17 is positioned at bottom that end outside water bath 2 is provided with half ramp structure 19, half ramp structures 19 and is provided with the gas outlet 20 of gap type.On centrifugal moisture trap 14, be provided with and the unit, inclined-plane 15 of discharging clean Gas phase Smoke shock, the outlet 16 of centrifugal moisture trap 14 is arranged on the opposite side of unit, inclined-plane 15.Wherein, half ramp structure 19 is identical with 15 angles of inclination, unit, inclined-plane, and the clean flue gas of discharging from gas outlet 20 directly clashes into unit, inclined-plane 15.
In the present invention, venturi scrubber 1 air inlet and water inlet position are different from the rotine positioning of current China for the venturi scrubber 1 of smoke gas treatment.Flue gas is from the venturi front side of venturi scrubber 1 to entering (and conventional mode is for axially entering), and introducing mode is: flue gas is divided into some roads (conventionally adopting 1～4 tunnel), that is: by several former smoke inlet 4 injections, enters in venturi scrubber 1.Several former smoke inlets 4 circumferentially evenly arrange along venturi scrubber 1, and the cigarette direction of entering of former smoke inlet 4 is the tangential of venturi scrubber 1 tube wall.Simultaneously, absorption liquid is from axially the entering of venturi scrubber 1 (and conventional mode is for entering in venturi venturi side direction), and setting has higher pressure and special nozzle 8, the glassware for drinking water that nozzle 8 sprays has speed and tighter spreadability faster, produce stronger injection power, flue gas in flue gas cross over pipe before venturi can be attracted in Venturi tube, at a high speed, high spreadability spray stream the flue gas of introducing is pushed through to venturi, the resistance that makes venturi scrubber 1 be-300～-100Pa(and the resistance of conventional venturi scrubber is 150～500Pa).Because venturi scrubber 1 is installed vertically downward, fume side enters, under go out, absorption liquid is enterprising, under go out, PM2.5 ultrafine dust will be condensed into larger particle in Venturi tube.
By the outlet top at venturi scrubber 1, be provided with cyclone 7, cyclone 7 is for being arranged on the combining structure of several blades on tube wall, and it forms certain resistance in exit, and the air pressure that guarantees venturi scrubber 1 is uniform state.Cyclone 7 can guarantee that the flue gas exporting from venturi scrubber 1, for evenly discharging, is uniform state by the air pressure that guarantees venturi scrubber 1, and in the time of can preventing gas discharge, local pressure is large, and causes the phenomenon that occurs liquid splash on liquid level 6.By be provided with trumpet type outlet 9 in the outlet of venturi scrubber 1, it is the delivery flow of even flue gas further, simultaneously, while discharging flue gas from outlet, can form at tube wall position negative pressure, the outer of the outside expenditure of trumpet type outlet 9 can prevent that the liquid of being blown by flue gas is back in pipe along tube wall.
Flue gas after water-bath impacting type dust removal process is upwards discharged and is entered centrifugal moisture trap 14 by water bath 2.Centrifugal moisture trap 14 is the gas unhurried current pipelines that clean flue gas delivery line 17 diameters of ratio are larger, flue runs in top, below is flue, flue gas flows downward through cyclone, and flue gas and liquid, under the effect of cyclone, form swirling eddy, the drop of larger particles is thrown toward the wall of unit, inclined-plane 15, because amount of liquid is larger, form downward continuous hollow cone liquid film, be conducive to dedusting; Liquid by wall interception and sedimentation flow back into water bath under Action of Gravity Field, and clean flue gas is by upper discharge.
