Those are the factors that affect the use of purification equipmentI. Resistance of purification equipmentThe general analysis of the resistance of purification equipment mainly has two theories: one is the channel theory, and the other is the resistance theory. After some research, the resistance of air filtration equipment is mainly related to the speed of airflow, the area of filtration, the structure of the equipment, the viscosity of the gas, the radius of the fibers, the density of the filling, etc. The theory that we can draw from a large amount of experimental data is that the experimental value and the theoretical calculation value are certain errors, mainly because the model established by the theory and the actual use of the This is mainly because the theoretical model does not exactly match the actual flow field, and that the assumptions made in the tests are also ideal, which is not the practice case. For the same type of filtration equipment, the size of the total resistance is different at the same rated air volume and structural resistance, because the total resistance is different due to the different resistance of the filter media. And different structure of air filter in the same air volume resistance is also not equal, which shows that the resistance will also be affected by the performance of the filter media. II. Efficiency of purification equipment The main factors affecting the efficiency of filtration equipment generally include the diameter of the particles in the airflow, the thickness of the filter media, structure and the speed of the airflow, temperature and humidity and dust content, etc. To sum up, the efficiency depends on the performance of the filter media, the nature of the airflow, and the speed of the airflow. According to the relevant research, we can learn that the structure of the air filter has a small impact on the filtration efficiency, mainly related to the performance of the filter media, while the change in airflow speed can also seriously affect the filtration efficiency. Therefore, in the same air volume using different models of filters, there will be some differences in the filtration efficiency, for example, in the rated air volume in the airflow filtration speed is reduced, but the filtration efficiency will not be reduced, then it proves that the filter does not have the problem of leakage. For the same type of filter, when the air volume, filter area, and the performance of the filter media are the same, the efficiency of filtration will not change much. In summary, we can learn that the performance of the air filter and the speed of airflow are important factors affecting its use, while the same structure, different filter media, filter efficiency, and resistance test results are different; the same model of the filter because of the different airflow speed, the efficiency, resistance test results are also different. |
