Exhausting system for building

Abstract

The invention discloses an exhausting system for a building and belongs to the technical field of ventilation of buildings. The exhausting system comprises a ventilating pipe, an injecting device, a hollow rotary shaft, a bearing and a guiding structure, wherein the ventilating pipe stretches into a base layer from the top of the building; the injecting device comprises a shrinking pipe, an outletpipe and a vacuum cavity; the shrinking pipe is transversely arranged in the vacuum cavity, and the large end port of the shrinking pipe is exposed out of the vacuum cavity; a side face of the vacuumcavity communicates to the outlet pipe, and the outlet pipe corresponds to a fine end port of the shrinking pipe; the hollow rotary shaft is fixed through a bearing fixed on the building, and the inner wall of the lower portion of the hollow rotary shaft is in clearance fit connection to the outer wall of the ventilating pipe; the upper portion of the hollow rotary shaft is fixedly connected to the injecting device, and the hollow rotary shaft communicates to the vacuum cavity; and the top of the injecting device is fixedly connected to the guiding structure. By using a wind power source on the top of the building, the exhausting system extracts air in a unit space in the building to the top of the building to accelerate air exchange speed between the unit space and the outer side of thebuilding, and the exhausting system is skillful in structure and has a very good economical benefit.

Description

【Technical field】 [0001] The invention relates to the technical field of building ventilation, in particular to a building ventilation system. 【Background technique】 [0002] In the field of architecture, the ventilation effect of buildings is a matter of great concern to residents, and it is also an issue that designers need to focus on. And for present urban area, because land resource is in short supply, therefore, usually be the situation of high-rise buildings everywhere, and between each high-rise building, often cause poor ventilation due to mutual shielding. In addition, the airflow on the roof of the huge building is fast and the wind is strong, but the ventilation of the internal housing units is extremely poor. 【Content of invention】 [0003] In view of the above existing problems, the present invention provides a building ventilation system. [0004] The technical scheme that the present invention takes is: [0005] A building ventilation system, including a...

AI Technical Summary

Problems solved by technology

For the current urban areas, due to the shortage of land resources, there are usually many tall buildings, and the high buildings often block each other, which often leads to poor ventilation.

In addition, the airflow on the roof of the huge building is fast and the wind is strong, but the ventilation of the internal housing units is extremely poor.
