Abstract
A pressure-variable air exhausting duct for building is composed of air exhausting pipeline, exhaustion guide pipe and airflow pressure changing unit. The position of air outlet for exhausting guide pipe is higher than that of the top of said pressure changing unit. Its advantages are no eddy and high exhaust effect.
Description
The present invention relates to the shared exhaust duct of a kind of building, the structure of pressure-varying air-exhausting duct of particularly a kind of each not smoke blowing of floor gap, not taint of odour.
China utility model patent CN2180711Y discloses a kind of pressure variable exhausting channel, it is by the guide pipe on the trunk line and the wall that sets within it, component for variable-pressure is formed, the exhaust passage of guide pipe is connected with air inlet port on the trunk line, the upper head plate present position of above-mentioned component for variable-pressure is higher than the residing position, gas outlet of described guide pipe, said structure with regard to make from down and on flue gas or gas stream when the space of flowing through between guide pipe and the component for variable-pressure, flow velocity is accelerated, play transformer action, can make place, guide pipe gas outlet be negative pressure or zero-pressure, but because the guide pipe gas outlet is lower than the upper head plate of component for variable-pressure, therefore flue gas stream or other gas of upwards flowing fast fail to be convened for lack of a quorum because of the unexpected broadening of top, guide pipe gas outlet exhaust duct, and in guide pipe exit generation stream swirl phenomenon, thereby influence flue gas or other gas purging effect.
The objective of the invention is to, a kind of structure of pressure-varying air-exhausting duct that can not produce the air whirl phenomenon in exhaust guide pipe exhaust ports is provided.
In order to achieve the above object, the solution that the present invention takes is, it is by the exhaust guide pipe on the gas emission pipe and the wall that sets within it, the air-flow component for variable-pressure is formed, described exhaust guide pipe is arranged on the inwall that described gas emission pipe is positioned at said flow component for variable-pressure opposite or side, and and described air-flow component for variable-pressure between remain with the gas communication space, the exhaust passage of described exhaust guide pipe is connected with air inlet port on the described gas emission pipe wall, be characterized in, the residing position of the exhaust opening of described exhaust guide pipe is higher than residing position, described air-flow component for variable-pressure top.After the exhaust opening present position of described exhaust guide pipe is higher than present position, described air-flow component for variable-pressure top, after can making mobile flue gas stream or gas flow to the air-flow component for variable-pressure top that reaches, jumps over from bottom to top, can in flowing, the gas emission pipe inwall direction to broad spread, make the air communication of the flow velocity that obviously do not slow down as yet cross above-mentioned exhaust guide pipe exhaust ports, so both guaranteed that this exhaust ports was negative pressure or zero-pressure, simultaneously can not make air-flow form eddy current herein yet, thereby improve the gas emission effect.Above-mentioned exhaust opening exceeds the height at air-flow component for variable-pressure top is advisable slightly to exceed, but the height that exceeds also belongs to protection scope of the present invention when big.
In order to save material, the said flow component for variable-pressure is to be made of a panel at least.When it constituted integrative-structure by front plate and bottom deflector, this two boards can be surface plate, also can have at least one to be cambered plate, and both connecting portions can be the shapes with bending rib (wedge angle), also can be arc surfaceds.When above-mentioned front plate, bottom deflector and both connecting portions are arc surfaced, just become the tabular air-flow component for variable-pressure of a monoblock cambered surface, also belong to protection scope of the present invention this moment.Certainly, the said flow component for variable-pressure can be provided with two side panels, can also set up top panel on this basis, and this top panel can be level board, clinoplain plate, cambered plate etc.Above-mentioned two side panels also can be cambered plate.
Make for convenience and the parts installation, preferably make between the inwall of the described gas emission pipe of at least one side and a corresponding side in the said flow component for variable-pressure both sides and remain with the gap, an i.e. determining deviation, this spacing generally can not blocked by inwall with it, stretches out one's hand easy for installation being advisable.
Above-mentioned exhaust guide pipe can be elbow shape guide pipe; By front tube wall, diapire and two guide pipes (being dustpan-shaped guide pipe) that sidewall constitutes; Or has cambered surface pipe of bottom lock plate etc.The transverse shape of described gas emission pipe can be rectangle, square, circle, ellipse or Long Circle etc.
Because the present invention has adopted said structure, the exhaust opening position of exhaust guide pipe is higher than the present position, top of described air-flow component for variable-pressure, can make that the exhaust ports of exhaust guide pipe is negative pressure or zero-pressure, can not make flue gas or gas form eddy current herein again, the eliminating of exhaust ports stream swirl phenomenon can eliminate the disturbance that air-flow from bottom to top discharges flue gas or gas to exhaust ports, so its advantage is, exhaust efficiency is able to obvious raising, and flue gas, gas emission effect are better.
