What are the factors affecting the air flow rate in the purification workshop?
Release time:2019-09-29 source:
The determination of air velocity in purification workshop will be affected not only by the amount of dust generated in the project, but also by other factors such as filter efficiency at all levels. So what are the factors that affect the selection of air velocity in the purification workshop? Next, Ed's Purification Editor will lead you to have a look.
1. The pollution degree of pollution sources mainly includes the consideration of many pollution sources, such as workshop components, number of personnel, operation activities, process equipment, process materials, etc., which should be changed according to the specific conditions.
2. Airflow pattern and distribution, such as unidirectional flow and non-unidirectional flow, are quite different from each other. Therefore, airflow velocity must be changed accordingly.
3. The control requirement of self-purification time. After all, the self-purification time of the purifying workshop depends mainly on the airflow speed if it wants to recover to the original cleanliness under the circumstances that the pollutants are constantly rising due to various logistics and people flow.
4. The efficiency of the last stage filter, because they are mutually reinforcing, can be reduced if one of them takes the maximum value.
5. Economy, after all, excessive airflow speed will increase investment and operating costs, while too small will affect the effect, so reasonable and comprehensive selection should be made according to the above factors.
