The blowing system of the aluminum air shower room is the core of ensuring the purification effect. Its design needs to comprehensively consider multiple aspects such as airflow organization, wind speed control, and filtration configuration. Through the synergistic effect of various elements, the dust particles attached to the surface of people or objects can be effectively removed. A scientific and reasonable blowing system design can ensure the efficient operation of the air shower room and build a reliable barrier for the clean space. The following is an analysis of its principles and mechanisms to ensure the purification effect from different dimensions.
The airflow organization form of the blowing system determines the removal efficiency of dust particles. Reasonable airflow organization must ensure that the airflow can fully cover the surface of people or objects and form an orderly flow path. Common designs will adopt multi-angle and multi-directional nozzle layouts to allow airflow to spray out from the side, top, or even bottom to avoid airflow dead corners. When people or objects enter the air shower room, the strong airflow is like an invisible "cleaning hand", wrapping and flushing the surface in all directions, so that dust particles are separated from the attached surface under the impact of the airflow and discharged from the air shower room with the airflow. This surrounding airflow organization allows every surface to be fully swept, thereby effectively improving the purification effect.
Precise control of wind speed is the key to ensure the purification effect of the blowing system. The appropriate wind speed can generate enough impact force to detach dust particles without causing harm to people or objects. If the wind speed is too low, the airflow cannot effectively blow off the dust; if the wind speed is too high, it may cause discomfort or even damage some sensitive items. The blowing system will maintain the wind speed in the ideal range through professional fan selection and air duct design. At the same time, it will also be equipped with a wind speed monitoring and adjustment device to monitor the wind speed changes in real time. When the wind speed is abnormal due to factors such as equipment aging and air duct blockage, it can be adjusted in time to ensure that the blowing force is always stable and effective during the air shower process, and the purification effect is continuously exerted.
The configuration of the filtration system is directly related to the cleanliness of the blown airflow. The blowing system does not simply blow out the indoor air, but ensures that the blown airflow is clean and free of impurities. Therefore, a multi-stage filtration device is set at the outlet of the fan, usually including a primary filter, a medium efficiency filter and a high efficiency filter. The primary filter can intercept larger dust particles and reduce the burden of subsequent filtration; the medium-efficiency filter further filters smaller particles; the high-efficiency filter can intercept micron-level or even nano-level fine particles to ensure that the airflow meets the purification standards required by the clean room. Only the clean airflow that has been filtered layer by layer can avoid secondary pollution to people or objects during the blowing process and truly achieve the purpose of purification.
The operation time control of the blowing system also has an important impact on the purification effect. If the air shower time is too short, the dust particles will not be completely removed in time; if the air shower time is too long, the use efficiency will be reduced. The blowing system will preset a reasonable air shower time based on the use scenario of the air shower room, the degree of pollution of people or objects, and other factors. At the same time, some air shower rooms also have intelligent sensing functions, which can automatically identify the objects entering the air shower room and adjust the air shower time according to the actual situation. For example, for people who carry more items, the air shower time is appropriately extended to ensure that the surface of the items is also fully blown. Through precise time control, the blowing system can ensure the purification effect while taking into account the convenience and efficiency of use.
The design and optimization of the air duct is an important part of improving the performance of the blowing system. The shape, size and smoothness of the inner wall of the air duct will affect the flow resistance and uniformity of the airflow. Reasonable air duct design will minimize structures such as bends and diameter changes, reduce the energy loss of the airflow in the air duct, and enable the airflow to be smoothly transmitted to each nozzle. At the same time, the inner wall of the air duct will be smoothed to avoid eddy currents caused by rough surfaces, resulting in uneven airflow distribution. In addition, the insulation design of the air duct should not be ignored to prevent condensation water from being generated due to temperature changes, which will affect the quality of airflow and the service life of the equipment. By optimizing the air duct design, it can ensure that the airflow is blown out from the nozzle stably and evenly, enhance the blowing effect, and ensure the purification quality.
The coordination between the blowing system and the overall structure of the air shower room is also crucial. The structure of the aluminum air shower room needs to provide stable support and reasonable space layout for the blowing system. The air shower room box should have good sealing to prevent airflow leakage and ensure the formation of an effective blowing space inside; the installation position of the nozzle should be consistent with the box structure to ensure that the airflow injection angle is accurate. At the same time, the door control system of the air shower room should be linked with the blowing system. The blowing system will only start when the door is completely closed to avoid air leakage affecting the purification effect. The door can only be opened after the air shower is over to ensure that people or objects enter the clean area after being fully purified, thus ensuring the purification efficiency of the air shower room as a whole.
The maintenance mechanism is the basis for ensuring the long-term and stable purification effect of the blowing system. With the increase of usage time, the filter of the blowing system will gradually become clogged, the fan performance may decline, and dust may accumulate in the air duct. Therefore, it is necessary to establish a complete maintenance plan, regularly replace the filter, clean the air duct, and check the operating status of the fan. Through timely maintenance, ensure that the filter always maintains good filtering performance, the fan provides stable air volume and air pressure, and the air duct is unobstructed, so that the blowing system can continue to maintain efficient purification capabilities during long-term use, and escort the stable operation of the clean environment.
