Problems solved by technology

The existing fresh air system can discharge part of the suspended particles and impurities in the room through the fresh air circulation, but since the particles are suspended in the room, the fresh air system needs to run for a long time, and it is possible to achieve the purpose of dust removal only when all the air is changed in the room. This process takes a long time to remove dust and the effect of dust removal limited

Embodiment 1

[0041] Below, the present invention is applied to a conference room with an area of ​​25 square meters and a height of 3.5 m as an example to illustrate the specific working process of the present invention.

[0042] In order to adapt to the ventilation and dust removal of the conference room, the number of air intake units of the air intake device is 6. On the horizontal plane, the air outlet of each air outlet inclined pipe is distributed in one direction along the virtual circle and is at the position of the virtual circle with itself. The tangents on it form an included angle of 30°. The included angle between the air inlet unit pipe 3 and the air outlet inclined pipe 4 on the vertical plane is 130° through the angle adjuster, and the lower end of the exhaust pipe 7 is the suction port and extends to the indoor height of 2m. The cross-sectional area of ​​the air inlet of the exhaust device 2 is 3 times of the cross-sectional area of ​​the air outlet inclined pipe 4. In the...

Embodiment 2

[0049] Below the present invention is applied to the dance hall of area 60 square meters, high 4m as an example, to set forth the specific working process of the present invention.

[0050] In order to adapt to the ventilation and dust removal of the dance hall, the number of air intake units of the air intake device is 12. On the horizontal plane, the air outlet of each air outlet inclined pipe is distributed in one direction along the virtual circle and is at the position of the virtual circle with itself. The tangents on it form an included angle of 20°. The angle between the air inlet unit pipe 3 and the air outlet inclined pipe 4 on the vertical plane is 120° through the angle adjuster, and the lower end of the exhaust pipe 7 is the suction port and extends to the indoor height of 2.2m. The cross-sectional area of ​​the air inlet of the exhaust device 2 is 4 times of the cross-sectional area of ​​the air outlet inclined pipe 4. In the present embodiment, the cross-section...

Abstract

The technical problem to be solved by the present invention is to provide a method for indoor ventilation and dust removal. Through the fresh air ventilation process, the dust particles and impurities suspended in the room can be gathered and quickly discharged to the outdoor, and the dust removal and ventilation efficiency is high. It includes an air intake device, which includes a plurality of air intake units, and the plurality of air intake units can form a vortex-shaped airflow in the room; an air exhaust device, whose suction port is facing the center of the vortex airflow.

Description

technical field [0001] The invention relates to a fresh air system, in particular to a method for ventilating and removing dust indoors. Background technique [0002] With the development of the economy and the improvement of people's living standards, more and more people begin to pay attention to their health and quality of life. In particular, more attention is paid to the indoor environment of buildings. Therefore, it has become a trend to install fresh air systems indoors. The fresh air system is based on sending fresh air into the room with special equipment on one side of the closed room, and then exhausting it from the other side to the outside by special equipment. A "fresh air flow field" will be formed indoors to meet the needs of indoor fresh air ventilation. Its specific implementation plan is: adopt high wind pressure, large flow fan, rely on mechanical force to send air from one side to the room, and use a specially designed exhaust fan to discharge to the o...
