Abstract
The utility model relates to a venturi pipe. The venturi pipe comprises a shrinkage section and an expanding section, wherein the lower end of the shrinkage section is connected with a first throat part, the lower end of the first throat part is connected with a gas storage tank, the lower end of the gas storage tank is connected with a second throat part, the peripheral side surfaces of the second throat part are respectively provided with shutters, and the lower end of the second throat part is connected to the top end of the expanding section. The venturi pipe has the beneficial effects that after a filter bag is in a filter state, airflow still can be discharged after entering the filter bag through the shutters, and thus the effective area of the filter bag can be increased while the filter bag is protected.
Description
Technical field
The utility model relates to a kind of Venturi tube.
Background technology
Venturi tube is the critical component of pulse jet sack cleaner, and vertical hanging is installed on bag cage of filter bag mouth place in pulse jet sack cleaner upper box, overlaps with the spot welding of bag cage.Venturi tube mainly plays a part to carry out gas flow guiding for compressed air and flue gas in pulse jet sack cleaner, by the air-flow correct guidance filter bag of injection pipe of deduster ejection, avoids air-flow inclination damage cloth bag sidewall and improves the impact depth of gas.In addition, it to also have an effect be promote the air-flow of ejection and fully mixed and carry out energy exchange by the secondary gas flow of its induction.
Utility model content
Goal of the invention of the present utility model is: the problem existing for prior art, provide a kind of with throat in the Venturi tube of air accumulator.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of Venturi tube, comprise contraction section and expansion segment, described contraction section lower end is connected with the first throat, described the first throat lower end is connected with air accumulator, air accumulator lower end is connected with the second throat, described second throat's surrounding side is provided with shutter, and described the second throat lower end connects in expansion segment top.
As preferred version of the present utility model, described the first throat and the second throat are highly 400mm.
As preferred version of the present utility model, described air accumulator is circular.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are: at filter bag, enter after filtration condition, air-flow emits after still can entering filter bag inside by shutter, have increased the effective area of filter bag in protection filter bag.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mark in figure: 1-contraction section, 2-expansion segment, 3-air accumulator, 4-the second throat, 5-shutter, 6-expansion segment.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
embodiment 1:
A kind of Venturi tube, comprise contraction section 1 and expansion segment 6, described contraction section 1 lower end is connected with the first throat 2, described the first throat 2 lower ends are connected with air accumulator 3, for systems stabilisation pressure, air accumulator 3 lower ends are connected with the second throat 4, and described the second throat 4 surrounding sides are provided with shutter 5, increase the effective area of filter bag, described the second throat 4 lower ends connect in expansion segment 6 tops.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
