The working principle of Dongguan clean room purification
The working principle of Dongguan cleanroom can be divided into the working principle of turbulent clean room and the principle of one-way clean room.
The main feature of a turbulent clean room is that the cross-section of the air flow from the flow to the outflow (from the air supply port to the air return port) is changed. The cross section of the clean room is much larger than the cross section of the air supply. The cross section of the working area of the whole room forms a uniform airflow. Therefore, the flow lines after the air outlet have a large or increasing angle with each other and a small radius of curvature. It is impossible for the airflow to flow in a single direction in the room, they will collide with each other, and vortices will be generated. This determines that the flow pattern of the turbulent clean room is: sudden flow; non-uniform flow.
This is more precise and comprehensive than turbulent flow to describe a turbulent clean room. Turbulence is mainly determined by the Reynolds number, that is, it is mainly affected by the flow rate. However, if a form of air supply with a high-efficiency filter is used, even if the flow rate is extremely low, the above-mentioned results will be produced. This is because it is a Sudden and non-uniform flows. Therefore, in this case, not only mixing due to turbulent flow between the stratospheres, but also mixing due to large reflux and vortices in the entire chamber.
So, in a nutshell, the working principle of the turbulent clean room is: when a clean air flow is sent from the air inlet into the room, it quickly diffuses and mixes around, and at the same time exhausts almost the same amount of air from the return air outlet. The clean air flow dilutes the polluted indoor air, dilutes the original indoor air with a high dust concentration, and reaches equilibrium. So the faster and more uniform the airflow spreads, the better the dilution technique will be.
