Air purifying device for cleaning indoor air and keeping local ventilation

Abstract

The invention discloses an air purifying device for cleaning indoor air and keeping local ventilation. The air purifying device comprises a first air purification mechanism, a second air purificationmechanism and a third air purification mechanism which have the adjustable spatial positions in space, and the air flow direction at an air outlet can be conveniently adjusted through the adjustment of the spatial positions and angles of the first air purification mechanism, the second air purification mechanism and the third air purification mechanism. In this way, the airflow direction at the local position of the experiment can be adjusted according to the needs of the experiment. During adjustment, the spatial positions of the first air purification mechanism, the second air purification mechanism and the third air purification mechanism can be set through a wind direction detector. The air purifying device can also realize automatic ash removal of filter screens. Through the automaticash removal of the filter screens, the blocking phenomenon of the filter screens caused by untimely ash removal is avoided, the purification effect of the equipment is further improved, and the equipment is enabled to operate efficiently.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an air purification device for maintaining local ventilation in a clean room. Background technique [0002] For the clean room in some occasions, for example, when performing experiments and other operations, it is often necessary to perform local ventilation and air purification on the experimental site, and in the ventilation process, the flow direction of the airflow is very important, especially for the operator and the experimental process For the protection in the environment, the airflow direction during air purification plays an extremely important role in the experimental protection. If the airflow direction is unreasonable, it is easy to have adverse effects, and even biological experiment accidents, and it is difficult to meet the requirements of local ventilation and purification. However, the current ventilation equipment is generally only provided with vent...

[0002] For the clean room in some occasions, for example, when performing experiments and other operations, it is often necessary to perform local ventilation and air purification on the experimental site, and in the ventilation process, the flow direction of the airflow is very important, especially for the operator and the experimental process For the protection in the environment, the airflow direction during air purification plays an extremely important role in the experimental protection. If the airflow direction is unreasonable, it is easy to have adverse effects, and even biological experiment accidents, and it is difficult to meet the requirements of local ventilation and purification.

However, the current ventilation equipment is generally only provided with ventilation holes at the purification equipment, and the ventilation angle only depends on the fins or louvers to adjust the air flow angle at the air inlet or outlet. The angle of the wind outlet cannot be changed for the airflow outside the purification device, which is difficult to achieve effective results for local ventilation and purification requirements
