Abstract
The utility model provides a high-rise building exhaust system and belongs to the technical field of buildings. The high-rise building exhaust system comprises a main exhaust duct. The high-rise building exhaust system is characterized in that the main exhaust duct is communicated with exhaust outlets in each floor, an upward exhaust duct formed by guide plates is fixedly arranged in the main exhaust at the lower end of the exhaust outlet, and a cross-sectional area of each floor is correspondingly increased along with heightening of building floors. Due to the fact that the upward exhaust duct formed by the guide plates is arranged at the lower portion of the exhaust outlets and the cross-sectional area of each floor is correspondingly increased along with the heightening of the building floors, air exhaust is smooth, the problems such as flowing backward of waste gas and tainting by other odor are effectively prevented, fresh air ventilation is achieved and exhaust effect is good.
Description
Technical field
The utility model belongs to technical field of buildings, is specially a kind of skyscraper exhaust system.
Background technology
Along with the raising of people's living standard, also more and more higher to the requirement of environment, to the also constantly lifting of requirement of architecture indoor air quality.In order to make the people living area that a pure and fresh environment be arranged, people are moving very large brains aspect the house building toxic emission, and the air exhaust passage of skyscraper also improves.The air exhaust passage that uses now, when waste gas is discharged, waste gas directly impinges upon on the main exhausting duct tube wall, then waste gas is towards up and down both direction motion, the air-flow that moves upward is owing to just making progress after impinging upon on the main exhausting duct tube wall, move upward flue gas speed and motion dynamics reduce, and exhaust effect does not reach optimum state; The waste gas that moves downward can pour in down a chimney back indoor, affects IAQ.
The utility model content
For the above-mentioned problems in the prior art, the purpose of this utility model is to design the technical scheme that a kind of simple in structure, skyscraper exhaust system that air draft is effective is provided, and can prevent the problems such as the pouring in down a chimney of waste gas in the air exhaust passage, taint of odour, and exhaust is smooth and easy.
Described a kind of skyscraper exhaust system, comprise main exhausting duct, it is characterized in that main exhausting duct is communicated with the exhaust outlet of each floor, be fixedly installed guide plate upwards on the main exhausting duct of exhaust outlet lower end and consist of air exhaust passage, the corresponding increasing along with increasing of architecture storey of the area of section of each floor master exhausting duct.
Described a kind of skyscraper exhaust system is characterized in that described guide plate is curved thin plate upwards.
Described a kind of skyscraper exhaust system is characterized in that described main exhausting duct is hermetically-sealed construction, and its top arranges main exhaust outlet.
Above-mentioned a kind of skyscraper exhaust system, by being set, guide plate upwards consists of air exhaust passage under exhaust outlet, and the area of section of each floor master exhausting duct corresponding increasing along with increasing of architecture storey, so that air draft is smooth and easy, the problems such as the pouring in down a chimney of waste gas, taint of odour have effectively been prevented, realized the fresh-air ventilation of each floor, good exhaust effect.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model cross-sectional structure schematic diagram;
Among the figure: 1-master's exhausting duct, 2-guide plate, 3-exhaust outlet, 4-air exhaust passage, 5-master's exhaust outlet.
The specific embodiment
The utility model is described in further detail below in conjunction with Figure of description.
As shown in the figure, this skyscraper exhaust system comprises main exhausting duct 1, main exhausting duct 1 is communicated with the exhaust outlet 3 of each floor, be fixedly installed guide plate upwards 2 on the main exhausting duct 1 of exhaust outlet 3 lower ends and consist of air exhaust passage 4, the corresponding increasing along with increasing of architecture storey of the area of section of each floor master exhausting duct 1.The staged that increases to of the area of section of each floor master exhausting duct 1 increases.Described guide plate 2 is curved thin plate upwards.Described main exhausting duct 1 is hermetically-sealed construction, and its top arranges main exhaust outlet 5, exhaust blower can also be set in the exit to promote air draft.
Operation principle is as follows: when some hugs the exhaust fan start of layer, waste gas enters in the main exhausting duct 1 by exhaust outlet 3, air exhaust passage 4, because guide plate 2 upwards being set in exhaust outlet 3 lower ends, when waste gas is discharged, nature will move upward fully along guide plate 2, and can allow the waste gas that moves upward keep higher movement velocity; And circulation area has been dwindled in the setting of guide plate 2 in varying degrees, air-flow is maximum at the flow velocity at eel-like figure loudspeaker place, according to aerodynamic principle, static air pressure at this place reduces suddenly, thereby the static pressure that makes this exhaust outlet 3 is lower than the indoor static pressure that each floor is not started shooting, and can be to indoor refluence waste gas; In order successfully to discharge with hugging that layer increases and the exhaust gas volumn that increases, the corresponding increasing along with increasing of architecture storey of the area of section of each floor master exhausting duct 1 is flowed equably to reach air-flow, accelerates waste gas is upwards discharged rapidly, reaches best exhaust effect.
Claims (3)
1. skyscraper exhaust system, comprise main exhausting duct (1), it is characterized in that main exhausting duct (1) is communicated with the exhaust outlet (3) of each floor, be fixedly installed guide plate (2) upwards on the main exhausting duct (1) of exhaust outlet (3) lower end and consist of air exhaust passage (4), the corresponding increasing along with increasing of architecture storey of the area of section of each floor master exhausting duct (1).
2. a kind of skyscraper exhaust system as claimed in claim 1 is characterized in that described guide plate (2) is curved thin plate upwards.
