Description
Technical field
The present invention relates to a kind of exhaust gas fume trap covers, in particular to the cover mouth structure of exhaust gas fume trap cover.
Background technique
Exhaust gas fume trap cover is the product being commonly used in waste gas pollution control and treatment, the cover with flared, the big mouth of cover
Towards exhaust gas to be trapped, osculum end is communicated with exhaust pipe at end, the negative pressure being connected to by exhaust pipe, make exhaust gas collected by cover and
Subsequent purification processing is carried out, avoids exhaust gas from endangering environment or influences human health.
However, often there is the presence of interference air-flow during trapping, trapping exhaust gas can not completely, up to not
To ideal trapping effect.
Summary of the invention
The present invention provides a kind of air-flow seal bootr mouth, and the purpose is to the interference for interfering air-flow of forgoing, and reaches optimal trapping
Effect.
To achieve the above object, the technical solution adopted by the present invention is that:
A kind of air-flow seal bootr mouth has the cover body in flared, and the osculum end of cover body is communicated with the exhaust of negative pressure
Pipe, for the big opening end of the cover body towards Target exhaust, the cover body has the central axes by big opening end and osculum end,
It is characterized in that:
Cover body big opening end outside be equipped with auxiliary cover wall, it is described auxiliary cover wall and the cover body big opening end it
Between form jet strip seam, jet strip seam is communicated with high pressure clean gas source, enable the jet strip slit at air screen wrap
Enclose or be isolated target gas source.
The air-flow seal bootr mouth, in which: the jet strip seam is connected with air-flow blower, the gas by admission line
Flow fan is communicated to outdoor or indoor pure air by fresh inlet.
The air-flow seal bootr mouth, in which: the injection direction of the jet strip seam is parallel to the central axes.
The air-flow seal bootr mouth, in which: form -30 between the injection direction and the central axes of the jet strip seam
Angle between -30 degree of degree.
The air-flow seal bootr mouth, in which: the air-flow blower is centrifugal high pressure fan.
The air-flow seal bootr mouth, in which: the shape of the auxiliary cover wall is similar to the big opening end of the cover body
Shape.
The air-flow seal bootr mouth, in which: the big opening end of the cover body is rounded or rectangular.
The air-flow seal bootr mouth, in which: the jet strip seam constitutes 360 degree of closed shapes.
The air-flow seal bootr mouth, in which: the part for the big opening end that the jet strip seam only surrounds the cover body is long
Degree.
The air-flow seal bootr mouth, in which: the big opening end of the cover body is arranged downward, setting upward, towards level side
To being arranged or be obliquely installed.
Compared with prior art, the invention has the advantages that: the jet strip slit at air screen can wrap
Target gas source is enclosed or be isolated, distribute target gas source can not, to all be collected by cover body, reaches near ideal
Trap effect.

Specific embodiment
Hereinafter reference will be made to the drawings is described in detail by way of example and not limitation some specific embodiments of the present invention.
Identical appended drawing reference denotes same or similar part or part in attached drawing.It should be appreciated by those skilled in the art that these
Attached drawing is not necessarily to be depicted true to scale.
As shown in Figure 1 and Figure 2, the present invention provides a kind of air-flow seal bootr mouth, has the cover body 1 in flared, cover body
1 osculum end is communicated with the exhaust pipe 2 of negative pressure, and towards exhaust gas, the cover body 1 has to be passed through the big opening end of the cover body 1
The central axes 3 of big opening end and osculum end, main improvements of the invention are:
A circle, which is equipped with, in the outside of the big opening end of cover body 1 assists cover wall 4, the auxiliary cover wall 4 and the cover body 1
The jet strip seam 5 of annular is formed between big opening end, the injection direction of the jet strip seam 5 is parallel to described 3 (such as Fig. 3 of central axes
It is shown), or -30 angles (as shown in Figure 4, Figure 5 respectively) spent between -30 degree are formed between the central axes 3；
The jet strip seam 5 is connected with air-flow blower 7 by admission line 6, and the air-flow blower 7 passes through fresh inlet 8
It is communicated to outdoor or indoor pure air.
When the present invention uses, as shown in figure 3, figure 4 and figure 5, air-flow blower 7 introduces pure air by fresh inlet 8,
Again by admission line 6 be sent into jet strip seam 5, jet strip seam 5 spray air-flow formed air screens, by exhaust gas source 9 be enclosed in or
Person keeps apart with interference wind, and the exhaust gas for distributing exhaust gas source 9 is substantially all to be collected by cover body 1, reaches intimate reason
The trapping effect thought.
Wherein, the air-flow blower 7 can be used centrifugal high pressure fan, pressure can 2000pa and it is following freely adjust, root
According to the intensity size of interference air-flow, its power can also be increased.
The shape of the auxiliary cover wall 4 is preferably similar to the shape of the big opening end of the cover body 1, if cover body 1 is big
The shape at mouth end is circle or rectangular, then the shape of cover wall 4 is assisted also mutually to should be round or rectangular.
(as shown in Figure 1) can be arranged in the big opening end of the cover body downward, can also be arranged upward or in the horizontal direction
It is arranged or is obliquely installed, air-flow seal bootr mouth structure of the invention can be used.
Moreover, the jet strip seam 5 can be close-shaped (as shown in Figure 2) for 360 degree, can not also close, but only
The partial-length of the big opening end of the cover body 1 is surrounded, the air screen being thusly-formed does not reconstruct 360 degree of end to end annulars,
And the portion perimeter of exhaust gas source 9 is only surrounded, and it can play the role of being locally isolated, it is in certain conditions of use and feasible
Embodiment.
Described above to be merely exemplary for the purpose of the present invention, and not restrictive, those of ordinary skill in the art understand,
Without departing from the spirit and scope defined by the claims, many modifications, variation or equivalent can be made, but will all be fallen
Enter within protection scope of the present invention.
