The specific embodiment
Now lift following examples and by reference to the accompanying drawings structure of the present invention and effect be elaborated.
As Fig. 1～shown in Figure 3, a kind of wet wall type venturi scrubber 10 that the present invention's the first preferred embodiment provides, it includes a Venturi tube 20, two conduits 30, a storage tank 40, a sprayer 50 and two overflow launders 60.
Venturi tube 20 has a contraction section 22, an expansion segment 24 and a throat 26, throat 26 is connected between expansion segment 24 and contraction section 22, its tube wall extends to the inboard of contraction section 22, contraction section 22 is formed with an air flow inlet 221 at the end away from throat 26, and expansion segment 24 is formed with an air stream outlet 241 at the end away from throat 26.
The top 32 of two conduits 30 is connected with the bottom of Venturi tube 20 contraction sections 22, and 34 of the bottoms of two conduits 30 are connected with storage tank 40.
When Practical manufacturing, Venturi tube 20 and two conduits 30 are with an outer tube 201 and a mutual winding of inner tube 203 and form, the contraction section 22 of Venturi tube 20 and two conduits 30 are formed at outer tube 201, the throat 26 of Venturi tube 20 and expansion segment 24 are formed in inner tube 203, and outer tube 201 also has a perforation 205 and supplies the top of inner tube 203 to place.
Sprayer 50 is located at contraction section 22 inboards of Venturi tube 20, can spray water smoke.
Two overflow launders 60 are to form by two connectors 62 being fixed in contraction section 22 outsides, two overflow launders 60 each via an opening 64 internal communication with Venturi tube 20 contraction sections 22.
The cleaning solution that venturi scrubber 10 is used for removing the waste gas particulate is to enter among Venturi tube 20 with the form of water smoke by sprayer 50.As the user when the bleeding point 44 of storage tank 40 is bled, pending waste gas can enter contraction section 22 through the air flow inlet 221 of Venturi tube 20, subsequently, the tiny water smoke that sprayer 50 produces will mix with this waste gas also and together enter in throat 26, so with particulate by eccysis in this waste gas.Air after being cleaned can be sequentially be disposed to the external world through storage tank 40 inside and bleeding point 44, and the cleaning solution by Venturi tube 20 throats 26 and expansion segment 24 flows in storage tank 40.
In addition, washings in storage tank 40 are to be imported in two overflow launders 60 through a circulation line (not shown) and two tube wall cleaning fluid supply pipes 66, and enter the contraction section 22 of Venturi tube 20 in the mode of overflow, with wetting its interior sidewall surface, and then avoid adhering to and piling up of dust, these cleaning solutions will flow back to storage tank 40 again along conduit 30 subsequently.
Along the cleaning solution that contraction section 22 tube walls flow, be attached to the particulate of wall due to eccysis in real time, therefore can effectively avoid accumulation of particulates and throat's obstruction of causing.In addition, the cleaning solution that should be used for wetting contraction section 22 tube walls is directly to flow into storage tank 40 through conduit 30, in fact the water smoke shape cleaning solution that only sprays for sprayer 50 of the cleaning solution by throat 26, therefore can effectively avoid because excessive washings enter throat's choking phenomenon that throat 26 causes, and because blocking the abnormal crushing that causes.
In addition, Venturi tube 20 and conduit 30 are to be formed by an outer tube 201 and a mutual winding of inner tube 203, and with regard to shape, outer tube 201 and inner tube 203 will be easier to be more manufactured than known Venturi tube, make required time, manpower and cost thereby can effectively reduce.In addition, the tube wall of Venturi tube 20 throats 26 extends to the inboard of contraction section 22, helps and will really introduce in conduit 30 along the cleaning solution that contraction section 22 interior sidewall surface flow.
Based on spirit of the present invention, this Venturi tube structurally also can have multiple variation.As shown in Figure 4 to 7, be a kind of wet wall type venturi scrubber 70 that the present invention's the second preferred embodiment provides, the structure of itself and previous embodiment is roughly the same, has equally a Venturi tube 80, two conduits 90 and a storage tank 94.
Venturi tube 80 is to be formed by an outer tube 82, an inner tube 84, a bushing pipe 86, a tube wall cleaning fluid supply pipe 87 and a mutual winding of dust washing liquid supply pipe 88, outer tube 82 is cylindrical and form a contraction section 83, its top side is provided with one and connects hole 821 for 87 plants of tube wall cleaning fluid supply pipe, tube wall cleaning fluid supply pipe 87 extends along the tangential direction of contraction section 83, make the cleaning solution contraction section 83 of can spiral helicine mode flowing through, outer tube 82 bottoms are provided with equally a perforation 822 and place for inner tubes 84.Inner tube 84 is formed with a throat 841 and an expansion segment 843, and its outer perimeter wall have one the ring rib 845, throat 841 tops also are provided with a plurality of spray orifices 847.Bushing pipe 86 is sheathed on around inner tube 84 and is positioned at the inboard of outer tube 82, and and outer tube 84 between form a dust washing liquid flow channel 861, dust washing liquid flow channel 861 is in communication with the outside by dust washing liquid supply pipe 88, and through the internal communication of each spray orifice 847 with inner tube 84, also amplexiform with the ring rib 845 of inner tube 84 bushing pipe 86 bottom sides.
Two conduits 90 are connected with outer tube 82 by a connecting seat 92, and Connection Block 92 sets firmly thereon for inner tube 84 simultaneously.
Adopt said structure, cleaning solution 941 in storage tank 94 can enter by this circulation line and tube wall cleaning fluid supply pipe 87 contraction section 82 of Venturi tube 80 equally, so that wetting tube wall, subsequently, this cleaning solution will flow out passage 823 through the tube wall cleaning fluid between outer tube 82 and bushing pipe 86 and enter Connection Block 92 inside, then flow into storage tanks 94 by each conduit 90.In addition, the washings after purification also can pass through dust washing liquid supply pipe 88, dust washing liquid flow channel 861 and each spray orifice 84 and spray into throat 841, in order to remove the particulate in waste gas.
The above; be only detailed description and the diagram of preferred embodiment of the present invention; the embodiment of all creation spirit according to the invention and variation similar with it; be included in category of the present invention; anyly be familiar with this skill person in the field of the invention, can think easily and variation or modify all should be encompassed in the application's scope of patent protection.
