Description
Technical field
Gas injection technique field is the utility model is related to, is specially a kind of energy-conservation deashing gas injection apparatus.
Background technology
Gas injection apparatus is to form being applicable for the flowing of high volume low pressure gas by supplying a small amount of compressed gas
In a kind of device of deduster.Deduster is generally located on the Work places of a large amount of discharge dust, and then captures the powder in air
Dirt and be to the air after outside discharge purification, the process of deduster purifying contaminated gas：The gas of pollution is entered by gas injection port
Enter to the filter bag of enclosure interior and filtered, the clean gas after filtering is discharged by exhaust outlet to outside.Polluting
When gas is filtered, filter bag outer surface be attached with dust or pollutant, and then increase the internal drag of deduster, influence
The efficiency of dust collection of deduster, in order to prevent these dust or pollutant plug filter bag, then pass through and each Venturi tube phase
Corresponding gas nozzle sprays compressed gas downwards and dust or pollutant is dropped.The compressed gas sprayed downwards is passing through text
It is accelerated during venturi, so as to spray to inside filter bag at a high speed, filter bag is vibrated and made the powder for being attached to filter bag exterior surface
Dirt or pollutant are dropped, and the dust or pollutant for dropping and being packed together are discharged from the unloading valve of bottom, original gas note
Enter the gas injection port that do not have of device, or gas injection port is located at downside, can so influence the flow direction of air, the flow velocity of air and former material
The use of material, so as to reduce ash-removal effect, cost is improved, therefore, we have proposed one kind to save deashing gas injection apparatus.
Utility model content
The purpose of this utility model is to provide a kind of energy-conservation deashing gas injection apparatus, to solve in above-mentioned background technology
The original gas injection apparatus proposed does not have gas injection port, or gas injection port is located at downside, can so influence the stream of air
Use to, the flow velocity of air and raw material, so as to reduce ash-removal effect, the problem of improving cost.
To achieve the above object, the utility model provides following technical scheme：One kind energy-conservation deashing gas injection apparatus, bag
Air duct body is included, the inwall of the air duct body is evenly arranged with the flow-disturbing wing, and the top of the air duct body is connected with lower Supporting cover, described
It is provided with upper top cover on the upside of lower Supporting cover, with being connected at the external margin of lower Supporting cover at the external margin of the upper top cover,
Gas injection port, the lower Supporting cover and upper top cover composition ring gaseous storage are welded with left and right sides of the top of the upper top cover
Room, and gas-flow deflector has been arranged circumferentially on the inside of upper top cover.
Preferably, the air duct body, lower Supporting cover and upper top cover are integrated die cast.
Preferably, the air duct body, the junction of lower Supporting cover are cambered surface transition plate.
Preferably, the acute angle that the axis of the flow-disturbing wing and air duct body is formed is 30 °.
Compared with prior art, the beneficial effects of the utility model are：The energy-conservation deashing gas injection apparatus passes through air-flow
The setting of guide plate so that the air flow of injection is certain, increases the drive draught effect of the device, by being put on gas injection port
Formula is set, and passes through adjustment so that the gas injection port of all devices is located on the same line, and only need to provide an appendix
Road, so as to reduce the cost of appendix.
Brief description of the drawings
Fig. 1 is the utility model structure diagram；
Fig. 2 is the utility model Fig. 1 sectional view；
Fig. 3 is the connection figure that the utility model uses.
In figure：1 air duct body, the 2 flow-disturbing wings, 3 times Supporting covers, 4 upper top covers, 5 gas injection ports, 6 gas-flow deflectors.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1-2 is referred to, the utility model provides a kind of technical scheme：One kind energy-conservation deashing gas injection apparatus, including
Air duct body 1, the inwall of air duct body 1 are evenly arranged with the flow-disturbing wing 2, and the top of air duct body 1 is connected with lower Supporting cover 3, lower Supporting cover 3
Upside be provided with upper top cover 4, with being connected at the external margin of lower Supporting cover 3 at the external margin of upper top cover 4, upper top cover 4
It is welded with gas injection port 5 at left and right sides of top, lower Supporting cover 3 and upper top cover 4 form ring gaseous storage room, and upper top cover 4
Inner side has been arranged circumferentially gas-flow deflector 6.
Wherein, air duct body 1, lower Supporting cover 3 and upper top cover 4 are integrated die cast, the connection of air duct body 1, lower Supporting cover 3
Locate as cambered surface transition plate, the acute angle that the axis of the flow-disturbing wing 2 and air duct body 1 is formed is 30 °.
Operation principle：The lower end of air duct body 1 is connected with dust-removal cloth-bag, appendix, appendix will be placed above the equipment
Bottom uniformly connect gas injection port connector, and gas injection port connector connection corresponding with the gas injection port 5 on upper top cover 4, and even
Place's sealing (such as Fig. 3) is connect, appendix in the inner chamber that aweather cylinder 1 forms with lower Supporting cover 3 of gas injection port 5 by providing air-flow, gas
Stream is drained into the inner chamber of air duct body 1 by the downside of gas-flow deflector 6, and the flow direction of air-flow tilts down, in the flow-disturbing wing 2
The lower progress of effect is movement-oriented, and the angle of the flow-disturbing wing 2 is 30 degree, avoids angle excessive and causes the influence to air-flow velocity,
When air-flow is discharged at gas-flow deflector 6, the air-flow of high flow velocities causes the upside of upper top cover 4 to produce negative pressure, in the work of negative pressure
Under, the gas of the upside of upper top cover 4 flows downward from the inner chamber of air duct body 1, so as to be filtered by dust-removal cloth-bag, reaches filtering
Effect.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out with a variety of changes in the case where not departing from principle of the present utility model and spirit, repaiied
