Abstract
The utility model discloses a kind of injection pipe of bag-type dust remover, be made up of seamless steel pipe, described seamless steel pipe evenly arranges the injection hole of three sections of different pore sizes successively, described injection hole is the arcuate socket of band flange, direction vertically downward, connects a mozzle under each injection hole.In described injection hole, range pulse valve is nearer, and its aperture is comparatively large, otherwise less.Range pulse valve winding-up aperture far away is little, the winding-up aperture little 0.5-2.0mm nearer than range pulse valve.Described injection tube is thin-walled welding pipe, and the caliber of its diameter and external pulse valve escape pipe is suitable.The utility model, by the size-modify to the injection hole of injection tube diverse location, makes every bar filter bag bear relatively uniform jetting pressure and larger air supply, and winding-up effect is better.
Description
Technical field
The utility model relates to Environmental-protecting dust-removing technical equipment, particularly a kind of injection pipe of bag-type dust remover.
Background technology
Long bag low-pressure pulse bag filter capable spray soot cleaning system is the important ash-clearing structure of sack cleaner, directly has influence on the running resistance of deduster, the service life of cloth bag and result of use.
The injection hole diameter of injection tube is in the past same size, and the air pulse of deduster is after pulse valve blowing, along on the length direction of injection tube, its speed and static pressure distribution are uneven, and the winding-up aperture in injection tube is same size, therefore its jet amount is different, and cause poor effect of jetting like this, dedusting is unholiness.
Utility model content
The utility model proposes a kind of injection pipe of bag-type dust remover, original blowing pipe structure improves, when compressed air spraying filter bag, every bar filter bag can be made to bear relatively uniform jetting pressure and larger air supply, winding-up effect is better.
The technical solution of the utility model is achieved in that
Injection pipe of bag-type dust remover, is made up of seamless steel pipe, and described seamless steel pipe evenly arranges the injection hole of three sections of different pore sizes successively, and described injection hole is the arcuate socket of band flange, and direction vertically downward, connects a mozzle under each injection hole.
The effect of above-mentioned mozzle is that the air flow energy that can make to eject is concentrated vertically downward, it is arranged on filter pocket mouths top, compared with built-in Venturi tube, does not affect the effective filtration area of filter bag, add secondary drainage amount, high pressure draught directly washing away filter bag can also be reduced.
In described injection hole, range pulse valve is nearer, and its aperture is comparatively large, otherwise less, and range pulse valve winding-up aperture far away is little, the winding-up aperture little 0.5-2.0mm nearer than range pulse valve.
This design just can be avoided because air pulse is after pulse valve blowing, the jetting pressure produced along speed on the length direction of injection tube and static pressure skewness is poor, it is made to be balanced by the injection hole of design different pore size size, thus making every bar filter bag bear relatively uniform jetting pressure and larger air supply, winding-up effect is better.
Described injection tube is thin-walled welding pipe, and its diameter is suitable with the caliber of the pulse valve escape pipe that outside is connected.
The length of described injection tube depends on filter bag number, the diameter of filter bag and the centre-to-centre spacing of filter bag that pulse valve can be jetted, and the wall thickness of injection tube is less than or equal to 4mm.
The beneficial effects of the utility model are, improve pulsed jet cloth filter soot cleaning system effect, even if at the air pulse of deduster after pulse valve blowing, along on the length direction of injection tube, in its speed and static pressure situation pockety, this blowing pipe structure still can make every bar filter bag bear relatively uniform jetting pressure and larger air supply, and blast pass is evenly distributed, make that every bar cloth bag deashing is clean, deashing is thorough, ensure the operational effect of deduster and normal.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the utility model injection pipe of bag-type dust remover.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
With reference to Fig. 1, injection pipe of bag-type dust remover, is made up of seamless steel pipe 3,4, and one end of seamless steel pipe 3 is connected with steel plate 1, and the other end is provided with pipe joint 2, is connected with the pulse valve escape pipe of outside.
Seamless steel pipe 3 sets gradually the injection hole of three sections of different sizes, be 20mm with four injection hole 7 diameters that pipe joint 2 is nearer, one section four injection hole 6 diameters of adjacent centre are 18mm, four injection hole 5 diameters of opposite side are 16mm, this size design mode have followed that " aperture that in injection hole, range pulse valve is nearer is larger, otherwise less " principle, make at air pulse after pulse valve blowing, along under speed on the length direction of injection tube and static pressure skewness situation, every bar filter bag bears relatively uniform jetting pressure and larger air supply, winding-up effect is better.
Above-mentioned injection hole 4,5,6 is the arcuate socket of band flange, and direction vertically downward, can not tilt, and the perpendicularity of its axial line is less than or equal to 0.4mm, otherwise blast pass can wash away filter bag.
Described injection hole 4,5,6 is designed to the arcuate socket being with flange, can not only reduce system winding-up resistance, and compressed air stream can be made to converge at some ejection as far as possible, in case airflow diverges is unordered wash away filter bag, thus structurally reduces the possibility of airflow scouring filter bag.
Connect a mozzle under each injection hole in described injection tube, the air flow energy ejected can be made to concentrate vertically downward.The effect of above-mentioned mozzle is that the air flow energy that can make to eject is concentrated vertically downward, it is arranged on filter pocket mouths top, compared with built-in Venturi tube, does not affect the effective filtration area of filter bag, add secondary drainage amount, high pressure draught directly washing away filter bag can also be reduced.
The utility model by improving on original blowing pipe structure, by designing the injection hole of different size, make when compressed air spraying filter bag, every bar filter bag can be made to bear relatively uniform jetting pressure and larger air supply, winding-up effect is better.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
