Abstract
The utility model discloses a kind of backflow proof to help and revolve transformation exhaust gas flue, it helps arranging device to form by flue gas exhaust pipeline and the built-in air-flow of each floor of flue gas exhaust pipeline, its air-flow helps arranging device to be helped by air-flow to revolve the gentle conductance of variable-pressure plate and revolve the auxiliary road of transformation form to helping, air-flow guiding helps revolves the rectangular triangle in bottom surface, transformation auxiliary road, two right-angle sides of rectangular triangle are connected on the flue gas exhaust pipeline wall below oil smoke air inlet port, formation air-flow guiding upwards of closing another side employing shrouding helps revolves the auxiliary road of transformation, air-flow helps and revolves in flue gas exhaust pipeline interior walls that variable-pressure plate is connected to below opposite.The utility model structure is simple, cost-saving; Induced-draft fan its air inlet port place static pressure when not opening is very little, forms draft in negative pressure state, overcomes the eddy current of sky cartridge type flue air inlet port, air curtain retardance and flue gas and pours in down a chimney phenomenon.
Description
Technical field:
The utility model relates to a kind of house kitchen central exhaust air flue, particularly relates to a kind of backflow proof and helps and revolve transformation exhaust gas flue.
Background technology:
High level or multi-storey building kitchen, washroom is by the oil smoke in flue gas exhaust pipeline drain chamber, dirty gas, the dwelling environment that peculiar smell etc. improve people is architectural design general at present, current exhaust gas flue basic framework is the square tube made by cement mortar, in order to prevent the smog due to a large number of users pour in smoke discharging pipe easily formed upper and lower floor letter family between flue gas pour in down a chimney and taint of odour, simultaneously, when air inlet port flue gas enters in flue, the flue gas that meeting and lower floor up arrange meets, two strands of air-flows are met and get along well mutually and are formed eddy current and air curtain, this eddy current and air curtain can produce to lower floor's flue gas is up the problem hindered, many designers are provided with smoke evacuation guide pipe and air-flow component for variable-pressure in exhaust gas flue, although this structure can alleviate stream swirl phenomenon, but, because pipeline Inner guide and component for variable-pressure too much take up space greatly, be easy to cause air-flow in smoke exhaust pipe to block up, do not reach smoke discharging effect.
Summary of the invention:
In order to solve above-mentioned house kitchen central exhaust air flue Problems existing, it is simple that the purpose of this utility model is to provide a kind of structure, not only improved discharge flue space, but also prevented the smoke blowing of reverse flowing of air flows levels, the backflow proof improving smoke discharging effect helps and revolves transformation exhaust gas flue.
The technical solution of the utility model realizes in the following manner:
A kind of backflow proof helps and revolves transformation exhaust gas flue, it helps arranging device to form by flue gas exhaust pipeline and the built-in air-flow of each floor of flue gas exhaust pipeline, its air-flow helps arranging device to be helped by air-flow to revolve the gentle conductance of variable-pressure plate and revolve the auxiliary road of transformation form to helping, air-flow guiding helps revolves the rectangular triangle in bottom surface, transformation auxiliary road, two right-angle sides of rectangular triangle are connected on the flue gas exhaust pipeline wall below oil smoke air inlet port, another side adopts shrouding to close formation air-flow guiding upwards and helps and revolves the auxiliary road of transformation, and air-flow helps and revolves in flue gas exhaust pipeline interior walls that variable-pressure plate is connected to below opposite.
Air-flow help revolve variable-pressure plate with connect angle between the walls: a≤40 °.
Described help that to revolve variable-pressure plate be triangle.
Described help that to revolve variable-pressure plate be inequilateral right-angled triangle.
Described air-flow guiding helps revolves that transformation auxiliary road upper port is minimum is positioned at oil smoke air inlet port top edge.
Good effect of the present utility model is: structure is simple, cost-saving; Built-in the helping of flue gas exhaust pipeline is revolved variable-pressure plate set-up mode and is made the oil smoke air-flow of discharging through exhaust fan present spiral escalation, the flowing velocity of gas is made to increase like this, dynamic pressure in pipeline is raised, static pressure reduces, induced-draft fan its air inlet port place static pressure when not opening is very little, form draft in negative pressure state, overcome the eddy current of sky cartridge type flue air inlet port, air curtain retardance and flue gas and pour in down a chimney phenomenon.
Accompanying drawing illustrates:
Fig. 1 is structural principle schematic diagram of the present utility model;
Fig. 2 is the plan structure schematic diagram of Fig. 1.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
By Fig. 1, Fig. 2 can find out: this backflow proof helps and revolves transformation exhaust gas flue, it helps arranging device to form by flue gas exhaust pipeline 1 and the built-in air-flow of each floor of flue gas exhaust pipeline 1, its air-flow helps arranging device to be helped by air-flow to revolve the gentle conductance of variable-pressure plate 2 and revolve the auxiliary road 3 of transformation form to helping, air-flow guiding helps revolves the rectangular triangle in bottom surface, transformation auxiliary road 3, two right-angle sides of rectangular triangle are connected on flue gas exhaust pipeline 1 wall below oil smoke air inlet port 4, formation air-flow guiding upwards of closing another side employing shrouding helps revolves the auxiliary road 3 of transformation, air-flow helps and revolves in flue gas exhaust pipeline interior walls that variable-pressure plate 2 is connected to below opposite.
Be it can also be seen that by Fig. 1, Fig. 2: air-flow help revolve variable-pressure plate 2 with connect angle between the walls: a≤40 °.
Described helping revolves variable-pressure plate 2 for triangle.
Described helping revolves variable-pressure plate 2 for inequilateral right-angled triangle.
Described air-flow guiding helps revolves that transformation auxiliary road 3 upper port is minimum is positioned at oil smoke air inlet port 4 top edge.
