Air pumping system applied to building

Abstract

The invention discloses an air pumping system applied to a building and belongs to the technical field of building ventilation. The air pumping system comprises a ventilation pipe, a spraying device,a hollow rotating shaft, a bearing, a guiding structure, filter structures and a protecting branch pipe. The ventilation pipe stretches from the top of the building into a base layer, ventilation branch pipes communicating with the ventilation pipe are arranged inside the building, and end ports of the ventilation branch pipes are connected with the filter structures; the ventilation pipe communicates with the protecting branch pipe; the spraying device is provided with a vacuum cavity with the vacuum condition; one side face of the vacuum cavity communicates with an outlet pipe, and the outlet pipe corresponds to a thin end port of a contracting pipe; the hollow rotating shaft is fixed through the bearing fixed to the building, and the inner wall of the lower portion of the hollow rotating shaft is connected with the outer wall of the ventilation pipe in a clearance fit mode; and the upper portion of the hollow rotating shaft communicates with the vacuum cavity, and the top of the spraying device is fixedly connected with the guiding structure. According to the air pumping system, air in a unit space inside the building is pumped out to the top of the building through an air powersource on the top of the building, and the air exchange speed of the unit space and the exterior of the building is increased.

Description

【Technical field】 [0001] The invention relates to the technical field of building ventilation, in particular to an exhaust system applied to buildings. 【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 an exhaust system applied to building construction. [0004] The technical scheme that the present invention takes is: [0005] A ventilatio...

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.
