Abstract
The utility model relates to an exhaust duct for buildings, in particular to a self-exhausting energy saving variable pressure exhaust duct. The technical proposal is as follows: the self-exhausting energy saving variable pressure exhaust duct comprises a main exhaust pipe (1) and an auxiliary exhaust pipe (2) which are in parallel; the top of the main exhaust pipe (1) is communicated with the air; the auxiliary exhaust pipe (2) is communicated with a room by an air inlet; the main exhaust pipe (1) and the auxiliary exhaust pipe (2) are communicated by a variable pressure injection draught (5); and the cross sectional area of the variable pressure injection draught is smaller than that of the air inlet. The exhaust duct is prepared with cement mortar without any mechanical structure, combustible material, metal, plastics and the like, does not consume electricity, saves energy and protects environment; because of the relative variable reduction of the variable pressure injection draught, variable pressure injection can be realized, so as to automatically pump the flue gas in the room out, exhaust the flue gas through a hood on the top without any power, and form the self-exhausting energy saving variable pressure exhaust duct. The exhaust duct is characterized by reasonable structure, automatic smoke exhausting, energy saving, environment protection and the like.
Description
Affiliated technical field:
The utility model relates to the energy-conservation variable-pressure exhaust passage of a kind of building exhaust duct, particularly self arrangement.
Background technology:
The effect of exhaust duct for building is the flue gas of getting rid of in the building, mostly adopts frame for movement at present, comprises exhaust fan, flap valve or the like, parts such as fire prevention is set, prevent that smoke blowing is poured in down a chimney in the exhaust duct, and the parts of exhaust duct mostly adopt metal or plastics to make; The problem that existing exhaust duct exists is: waste electric energy during exhaust fan work, and exist and pollute, use metal or plastics not only to raise the cost, and waste energy.
The utility model content:
The utility model purpose provides the energy-conservation variable-pressure exhaust passage of a kind of self arrangement, without frame for movement, and automatic smoke exhausting gas, energy-conserving and environment-protective solve the problems referred to above that exist in the background technology.
The technical solution of the utility model is: the energy-conservation variable-pressure exhaust passage of self arrangement comprises main exhaust pipeline and the secondary extract duct that is set up in parallel, the top of main exhaust pipeline is communicated with atmosphere, secondary extract duct is communicated with by in air intake and the room, is communicated with by transformation injection air port between main exhaust pipeline and the secondary extract duct.
Said transformation injection air port sectional area is less than the sectional area of air intake, and air intake is positioned at the centre.
Top, said transformation injection air port can be provided with wind protection screen, makes flowing of flue gas more meet the hydrodynamics rule, and is more unobstructed.The top in transformation injection air port also can not be provided with wind protection screen.
The cross sectional shape of main exhaust pipeline and secondary extract duct all is an arbitrary shape, and for example: circle, semicircle, square, rectangle or the like also can be the combinations of above-mentioned shape.Top at main exhaust and secondary exhaust duct is provided with air exhausting device, and air exhausting device comprises blast cap and air vent, and blast cap is arranged on the top, and air vent is arranged on the four sides of air exhausting device, and Open Side Down for air vent, and purpose is to improve exhaust efficiency.
The air intake quantity that secondary extract duct is communicated with the room is arbitrarily, can be one, also can be more than two, according to the room needs air intake quantity is set, for example: two air intakes can be set in the kitchen, and one is used to discharge the oil smoke that produces when cooking, and another is used for natural ventilation.If an air intake is set, said transformation injection air port sectional area is less than the sectional area of this air intake; If two above air intakes are set, said transformation injection air port sectional area is less than wherein maximum air intake sectional area.
According to the number of plies difference of building, said secondary extract duct is combined by the plurality of sections independent tubes, the room of the corresponding coupling of each segment pipe one deck building.Two groups of secondary exhaust ducts can be set in main exhaust.
The utility model can adopt cement mortar to make, and does not have frame for movement, does not have combustible material, does not also need to use metal, plastics or the like consume electric power not during use, energy-conserving and environment-protective; Because the relative reducing in transformation injection air port can reach the transformation ejector action, the flue gas in the room is extracted out automatically, discharge by the air exhausting device at top, without any need for power, form the energy-conservation variable-pressure exhaust passage of self arrangement.
The utlity model has characteristics such as rational in infrastructure, automatic smoke exhausting, energy-conserving and environment-protective.
Description of drawings:
Accompanying drawing is the Facad structure schematic diagram of the utility model embodiment.
Among the figure: main exhaust pipeline 1, secondary extract duct 2, air intake 3 and 4, transformation injection air port 5, wind protection screen 6, blast cap 7, air vent 8, air exhausting device 9.
The specific embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
In an embodiment, the energy-conservation variable-pressure exhaust passage of self arrangement comprises main exhaust pipeline 1 and the secondary extract duct 2 that is set up in parallel, the top of main exhaust pipeline 1 is communicated with atmosphere, secondary extract duct 2 by air intake 3 and 4 with the room in be communicated with, be communicated with by transformation injection air port 5 between main exhaust pipeline 1 and the secondary extract duct 2,5 tops, transformation injection air port are provided with wind protection screen 6, make flowing of flue gas more meet the hydrodynamics rule, and are more unobstructed.The cross sectional shape of main exhaust pipeline and secondary extract duct all is a square, at the top of exhaust duct air exhausting device 9 is set, air exhausting device comprises unpowered spiral blast cap 7 and air vent 8, and blast cap is arranged on the top, air vent is arranged on the four sides of air exhausting device, and Open Side Down for air vent.The air intake quantity that secondary extract duct 2 is communicated with the room is two, an oil smoke that is used to discharge generation when cooking, and another is used for natural ventilation, and said transformation injection air port sectional area is less than wherein maximum air intake sectional area.The utility model adopts cement mortar to make, and does not have frame for movement, does not have combustible material, does not also need to use metal, plastics or the like consume electric power not during use, energy-conserving and environment-protective; Because the relative reducing in transformation injection air port can reach the transformation ejector action, the flue gas in the room is extracted out automatically, discharge by the air exhausting device at top, without any need for power, form the energy-conservation variable-pressure exhaust passage of self arrangement.
