Embodiment one
Shown in Fig. 1-Fig. 3, present embodiments provide a kind of depositing dust case; The schematic diagram of the depositing dust case that Fig. 1 provides for the utility model embodiment; The structural representation of the depositing dust case that Fig. 2 provides for the utility model embodiment; The structural representation of the dividing plate that Fig. 3 provides for the utility model embodiment; Wherein, the direction of arrow shown in Fig. 1 is air-flow direction in casing.
Shown in Fig. 1-Fig. 3, the depositing dust case that the present embodiment provides, for reducing the dust in air, belongs to environment-friendly products; Described depositing dust case comprises casing 1; Casing 1 is provided with air inlet 101 and air outlet 102, flows along air inlet 101 towards the direction of air outlet 102 to make air; Air inlet 101 produces the operation field 4 of dust for being communicated with; This operation field 4 such as can remove the job site of pipeline for the spraying producing the dust such as quartz sand, iron rust and inside pipe wall deposit, also can be the operation field 4 that down-hole great Xiang, belt-conveying lane, belt feeder transfer point, return airway, coal-winning machine support etc. produce dust.
Be installed with dividing plate 2 and spray system 3 in casing 1, air flows through dividing plate 2 and spray system 3, flows in the direction towards air outlet 102.
Be provided with water tank 5 below spray system 3, water tank 5 is installed in casing 1.
The case of depositing dust described in the present embodiment, by in the air flue that flows at air, dividing plate 2 is set, change direction when flowing through dividing plate 2 to make air and reduce the speed of air flowing, thus part dust grain contained in air and dividing plate 2 are bumped against and sedimentation, especially after the dust grain that particle is larger and dividing plate 2 bump against, meeting sedimentation, achieves preliminary depositing dust; By in the air flue that flows at air, spray system 3 is set, when flowing through spray system 3 to make air, part dust grain contained in air is made to contact with the water that spray system 3 sprays, bump against and sedimentation, especially the dust grain that in air, remaining particle is less contacts with water, bump against after can sedimentation, achieve depositing dust again, thus substantially remove the dust flowed through in the air of depositing dust case; By water tank 5 to collect the water of spray, avoiding water to flow out depositing dust case affects environment, and affects the constructions such as job site, operation.To sum up, this depositing dust box structure is simple, with low cost, can effectively remove, the dust reduced in air, the especially dust of the bulky grain such as quartz sand, iron rust thing, avoids the air with a large amount of dust and flows in air.
In the possibility of the present embodiment, be also installed with deflector 6 in casing 1, deflector 6 is between air inlet 101 and dividing plate 2.By deflector 6 to change the direction of air and to reduce the speed of air flowing, the dust making partial particulate larger on the one hand drops because of the weight of self, thus the Dust Capacity in reduction air, also make dividing plate 2 obtain the relatively low air-flow of speed, be convenient to dividing plate 2 and reduce Dust Capacity in air; Decrease the noise that swiftly flowing air produces in casing 1 on the other hand.
In the possibility of the present embodiment, casing 1 comprises top board 103 and base plate 104, and multiple dividing plate 2 is alternately fixed on top board 103 and base plate 104, and the length of dividing plate 2 is not less than the distance of half between top board 103 and base plate 104.Dividing plate 2 with to be vertical setting by the air draught of dividing plate 2 or near normal is arranged; By the some vertical partition plates 2 of device in air air flue, the direction changed when flowing through dividing plate 2 to make air speed that is comparatively large and that reduce is comparatively large, thus makes to bump against with dividing plate 2 and the dust grain of sedimentation is more; By the dividing plate 2 of certain size is alternately fixed on top board 103 and base plate 104, to change the direction of air draught flowing further, thus reduces the speed of air flowing, to make air fully contact with spray system 3, make the dust in air substantially remove.Preferably, the length of dividing plate 2 equals or slightly larger than the distance of half between top board 103 and base plate 104.
Further, dividing plate 2 is evenly provided with multiple passage 201; To reduce the resistance of air by dividing plate 2, the air-flow of dispersion air, be separated into several more weak air draughts with the air draught making one stronger by multiple passage 201, thus it is more abundant that air is contacted with spray system 3, makes the dust in air remove cleaner.
Wherein, passage 201 can be multirow, multiple row distribution on dividing plate 2; The shape of passage 201 can be, but not limited to circle, rectangle, polygon, star, irregular figure etc.; Preferably, passage 201 is circular, so that the production and processing of dividing plate 2.
In the present embodiment, spray system 3 comprises multiple shower 301, and shower 301 is parallel to dividing plate 2, so that the water that spray system 3 sprays contacts more abundant with air; One or more dividing plate 2 is provided with between multiple shower 301; In spray system 3, arrange dividing plate 2, to weaken the air-flow of air further, and minimizing mixes the water of dust along with air-flow outflow depositing dust case.
Wherein, shower 301 can and dividing plate 2 interval arrange, also between adjacent separator 2, multiple shower 301 can be set; The quantity arranging shower 301 between concrete adjacent separator 2 can be determined according to factors such as the kinds of the dustiness in air, dust-laden.
In the present embodiment, deflector 6 is fixedly connected with top board 103, so that deflector 6 better plays guide functions; And the angular range between deflector 6 and top board 103 is 30 degree-60 spends, this angular range can make the guide functions of deflector 6 best, be easier to make air change its direction along deflector 6, the also larger speed reducing air flowing, thus the noise being more beneficial to the larger dust of partial particulate because of the weight of self and dropping and reduce that swiftly flowing air produces in casing 1.Preferably, the angular range between deflector 6 and top board 103 is 45 degree.
The direction that in the present embodiment, air inlet 101 is arranged and the direction that air outlet 102 is arranged can be arranged at an angle; Preferably, the direction that air inlet 101 is arranged is vertical with the direction that air outlet 102 is arranged, so that change the direction of air flowing, thus reduce further the speed of air flowing, the dust making partial particulate larger drops because of the weight of self, thus reduce further the Dust Capacity in air.
In the possibility of the present embodiment, casing 1 inner surface is fixedly connected with cushion course (not shown) in whole or in part; By cushion course so that the frictional force between the air of buffering flowing and casing 1, to reduce the noise of air flowing generation.The material of cushion course can be such as one or more in rubber, silica gel, foam, plastics, and preferably, the material of cushion course is rubber.
In the present embodiment, the length range of casing 1 is 2m-6m, and width range is 1.5m-3m, and altitude range is 1.2m-2m.
