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, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, all other embodiments that those of ordinary skill in the art are obtained on the premise of not making creative work, broadly fall into the scope of this utility model protection.
Embodiment one
Such as Fig. 1-Fig. 3, the spraying and blowing organ of depositing dust in this utility model embodiment a kind of flue 1 of offer, including multiple winding-up assemblies, multiple described winding-up assemblies are circular layout along walling of flue 1 circumference；Wherein, each winding-up assembly includes that nozzle 3 and nozzle carrier 2, described nozzle carrier 2 are arranged on walling of flue 1, and described nozzle 3 is installed in flue 1 by described nozzle carrier 2, and described nozzle carrier 2 has the flowing lumen of the described nozzle of connection 3 and outside winding-up liquid source；The spray region split of each described nozzle 3 forms the spray face that at least can cover described flue 1 cross section.By the circle nozzle 3 being circular layout, can reach the spray area that flue 1 cross section is completely covered, thus ensure spraying effect.
Wherein, for the flue 1 being relatively large in diameter, nozzle carrier 2 can partly stretch in flue 1 so that nozzle 3 close to flue 1 center, thus can ensure to cover the whole cross section of flue 1；Stretch near the nozzle carrier 2 in flue 1 owing to there is spray blind area (i.e. part between nozzle 3 and flue 1 inwall), adjacent nozzle 3 blowing direction can be set towards this region, can arrange further each nozzle carrier 2 wear direction and winding-up angle direction adjustable, adjust the relative angle between adjacent two nozzle carriers 2 and the angle of nozzle 3 winding-up as required, spray is completely covered with cross section in ensureing flue 1.In the present embodiment, as preferably, each nozzle 3 is all close to walling of flue 1 and arranges, to avoid spraying the existence of blind area, specifically: for the nozzle carrier 2 being radially arranged along flue 1, the end being used for installing nozzle 3 of each nozzle carrier 2 is all embedded in walling of flue 1, and each nozzle 3 is just exposed to outside walling of flue 1 and blowing direction is along flue 1 radial direction, this mode still suffers from certain spray blind area, and the spraying effect for the flue gas of walling of flue 1 operation that reclines is poor；Therefore, nozzle carrier 2 can be arranged be radially arranged along non-flue 1, the i.e. length direction of nozzle carrier 2 radially has an angle with flue 1, and the convenient blowing direction adjusting nozzle 3 radially has an angle with flue 1 so that the winding-up scope of nozzle 3 can cover neighbouring walling of flue 1.Such as Fig. 1 and Fig. 3, in the present embodiment, the blowing direction of each described nozzle 3 is set and all becomes 42 ° ~ 50 ° angles with flue 1 axis, preferably 45 °.Further, the blowing direction of each nozzle 3 is set all towards coming flue gas direction so that spray liquid and flue gas are counter current contact, improves spraying effect.
Continue the structure of above-mentioned spraying mechanism, and each winding-up assembly can be along walling of flue 1 circumference uniform intervals arrangement, and in Fig. 2, on walling of flue 1, uniform intervals arranges 4 groups of winding-up assemblies, and walling of flue 1 arc length between adjacent two winding-up assemblies is identical；Also can arrange by non-uniform spacing, can adjust according to flue 1 flow field.In the present embodiment, as preferably, the density of the described winding-up assembly being installed on walling of flue 1 top is more than the density of described nozzle 3 assembly being installed on flue 1 bottom, using said structure, may be formed at flue 1 internal upper part spraying intensity relatively big, bottom spraying intensity is relatively small, top spray liquid can flue gas with lower section meet during declining further, thus play effect further, improve treatment effect, and save spray liquid consumption.
Continue the structure of above-mentioned spraying mechanism, each nozzle carrier 2 can individually feed liquor, also following preferred structure can be taked: described spraying and blowing organ also includes nozzle ring connecting tube 4, described nozzle connecting pipe 4 is sheathed on outside flue 1, and connect with the flowing lumen of each described nozzle carrier 2, it is provided with at least one inlet 5 in described nozzle connecting pipe 4.Such as Fig. 1 and Fig. 2, this nozzle ring connecting tube 4 can be a complete cirque structure；Alternatively having the arc-shaped structure at both ends, its both ends connect two adjacent nozzle carriers 2 respectively, can realize each nozzle carrier 2 feed flow.Depending on quantity visual flue 1 diameter of inlet 5, when flue 1 be relatively large in diameter, nozzle 3 quantity more time, multiple inlet 5 can be set, normal to ensure the jetting pressure of each nozzle 3；When flue 1 diameter is less, an inlet 5 can be only set.
In the present embodiment, each described nozzle 3 is double fluid atomizer 3, and Ke Yilu enters liquid of reuniting, and compressed air is entered on a road.
Embodiment two
This utility model embodiment relates to a kind of circular flue 1, is disposed with the most a set of spraying and blowing organ along flue gas circulating direction in described flue 1, and this spraying and blowing organ uses the spraying and blowing organ provided in embodiment one, and here is omitted for concrete structure.The quantity of spray equipment is depending on kind class feature and the process requirement etc. that process flue gas, and adjacent two spraying and blowing organs intervals are arranged, and spacing determines with actual condition.
Embodiment three
This utility model embodiment relates to a kind of coal unit, and including the flue 1 of the flue gas transporting for being produced by unit to cleaner unit, described flue 1 uses the circular flue 1 that above-described embodiment two is provided, and described spraying and blowing organ connects reunion liquid source.
The miniature coal unit of the coal unit that the present embodiment relates to especially below 300MW, owing to flue 1 diameter of miniature coal unit is relatively small, the application effect of the most above-mentioned spraying and blowing organ is preferable, it is ensured that the cross section of flue 1 is completely covered.
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 modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
