In the technique scheme; Preferably; The downstream of described first gas outlet are provided with first filter, and and then the downstream of described second gas outlet are provided with the downstream dust separation unit or second filter, and the filtration grade of described first filter is higher than the filtration grade of second filter.
Further preferred, described second gas outlet is looped around the outside oral area in described first gas outlet by several along circumferencial direction and constitutes.
Further preferred, described first filter and second filter are arranged side by side about being, or further preferred, and described first filter and second filter are to superpose up and down to be provided with.
In the technique scheme, preferably, the elevation of water at place, described first gas outlet is lower than the elevation of water at place, described second gas outlet.
Through implementing above-mentioned technical scheme; The utility model obtains following beneficial effect: through two gas outlets are set; Make air-flow after rotation, to discharge from different gas outlets according to the particle diameter difference; Promptly realize out the classification of entraining air stream, can be convenient to like this air-flow after the classification is done adaptive processes, thereby improved the comprehensive separative efficiency of cyclone separator.
Description of drawings
Accompanying drawing 1 is the structural representation of the cyclone separator of the utility model;
Wherein: 1, first order cyclonic separation unit; 11, cylindrical shell; 12, first order cyclonic separation chamber; 13, filter mantle; 2, second level cyclonic separation unit; 21, inner core; 22, second level cyclonic separation chamber; 23, air inlet; 24, mesh filter member; 25, core tube; 26, first gas outlet; 27, second gas outlet; 28, first filter; 29, second filter.
The specific embodiment
Below in conjunction with embodiment shown in the drawings the technical conceive of the utility model is further set forth:
As shown in Figure 1, this cyclone separator has two stage cyclone formula separative element, is specially first order cyclonic separation unit 1 and cyclonic separation unit, the second level 2, and cyclonic separation unit, the second level 2 is positioned at the inside of first order cyclonic separation unit 1.
First order cyclonic separation unit 1 comprises the cylindrical shell 11 of a hollow, and cyclonic separation unit, the second level 2 comprises the inner core 21 of a hollow, and inner core 21 is positioned at cylindrical shell 11 inside and both central lines.Space between the outside wall surface of the internal face of cylindrical shell 11 and inner core 21 forms first order cyclonic separation chamber 12, and the inside of inner core 21 forms cyclonic separation chamber, the second level 22.Cylindrical shell 11 is provided with an air intake (not shown) that is used for dust-contained airflow is imported to 12 inside, first order cyclonic separation chamber; The top in first order cyclonic separation chamber 11 is equipped with a filter mantle 13 that has some through holes; These through holes on the filter mantle 13 constitute the portion of giving vent to anger of first order cyclonic separation unit 1, and the air-flow of process first order cyclonic separation chamber 11 preliminary cyclonic separation flows out from these through holes.Offer air inlet 23 on the inner core 21, air inlet 23 places are provided with mesh filter member 24, cross in the cyclonic separation chamber, the air inlet 23 inflow second level 22 through the air communication of the first cyclonic separation unit, 1 initial gross separation and separate once more.As shown in the figure, the top in cyclonic separation chamber, the second level 22 is provided with the portion of giving vent to anger of the cyclonic separation unit, the second level 2 that comprises one first gas outlet 26 and one second gas outlet 27.First gas outlet 26 is positioned at the bottom of the core tube 25 of hollow, and second gas outlet 27 is between the inwall of the outer wall of core tube 25 and inner core 21.The elevation of water at 26 places, first gas outlet is lower than the elevation of water at 27 places, second gas outlet, and second gas outlet 27 is positioned at the periphery of first gas outlet 26.(in fact, second gas outlet 27 also can be made up of along the oral areas that circumferencial direction be looped around 26 outsides, first gas outlet several.) and then the downstream that and then are provided with first filter, 28, the second gas outlets 27, the downstream of first gas outlet 26 be provided with second filter 29.Air-flow rotates in the second cyclonic separation chamber 22 when separating; Because the bulky grain dust is positioned at the periphery of cyclonic chamber; The particle size of the dust-contained airflow that flows out from second gas outlet 27 is greater than the particle size of the dust-contained airflow that flows out from first gas outlet 26; Therefore in order to make the particle size of the dust-contained airflow that flow out each filter and corresponding gas outlet be complementary, the filtration grade of first filter 28 is higher than the filtration grade of second filter 29.
In the present embodiment, on the relation of position, first filter 28 is positioned at the top of second filter 29; Both are superimposed up and down; And according to the flow direction of air-flow, first order filter 28 is positioned at the downstream of second level filter 29, by the air-flow of second gas outlet, 27 outflows; Behind second filter, 29 streams, upwards discharge again through first filter, 29 backs.After avoiding large and small particle dust all to flow out like this from a gas outlet, the generation of bulky grain dust blocking highly effective filter.
In addition, first filter and second filter also can according to about side by side mode be provided with.Like this; When the pairing filter in downstream, a gas outlet in first gas outlet or second gas outlet takes place to stop up; Air-flow can flow out from another gas outlet, makes two filters to be utilized fully like this, has reduced airflow obstruction; Simultaneously can clear up or clean some filters individually, prolong the service time of cyclone separator.
Set forth the course of work of this cyclone separator below:
The first order cyclonic separation chamber 11 of dusty gas in air inlet flows into cylindrical shell 11; Dust-contained airflow rotates separation in first order cyclonic separation chamber 11; Dust falls into the dust storage chamber of bottom; Air-flow through initial gross separation flows out first order cyclonic separation chamber 11 from filter mantle 13, and through separating once more in the cyclonic separation chamber, the mesh filter member 24 inflow second level 21, air-flow rotates in cyclonic separation chamber, the second level 21 subsequently; Be positioned at inner comparatively clean air-flow and flow out, then discharge through first filter 28 from first gas outlet 26; Be positioned at the peripheral air-flow that contains greater particle size and flow out, filter through second filter 29 again, flow out from first filter 28 more at last from second gas outlet 27.
The downstream of the second above-mentioned gas outlet if necessary; Also can and then establish a downstream dust separation unit; Through will get rid of by second gas outlet, contain oarse-grained dust and separate once more; Make the dustiness in the air-flow reduce, then filter the back and discharge at filter through the independent filter or the first order.
The foregoing description only is the technical conceive and the characteristics of explanation the utility model, and its purpose is to let the personage who is familiar with this technology can understand content of the utility model and enforcement according to this, can not limit the protection domain of the utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection domain of the utility model.
