Filtration accuracy
The maximum diameter of the impurity particles that are allowed to pass. Affect the filtering accuracy of the key is the filter, according to the needs of the back of the components to choose a different filter, so that it reaches the appropriate filtering accuracy.
Flow characteristics
Refers to the pressure at a certain inlet pressure through the filter and the filter at both ends of the pressure drop between the curve, the actual use, the best pressure loss in the range of less than 0.03MPa optional. In the air filter, affecting the flow characteristics of the main body and filter.
Water diversion efficiency
Refers to the separation of water and air inlet air contained in the ratio of water generally require air filter water diversion efficiency of not less than 80% of the main water diversion efficiency.
Air filters with different concentrations of different filtration efficiency.
(1) Weight efficiency Dust concentration is expressed as mass concentration (g / m³)
(2) counting efficiency Dust concentration to count the concentration (pc / L) to represent
(3) sodium flame efficiency to sodium chloride solid particles as a dust source. Sodium chloride particle concentration was measured by photoelectric flame photometer. Sodium flame efficiency and counting efficiency.
Filter resistance
The resistance of the new filter at rated air flow is called the initial resistance; at rated air flow, the capacity of the filter to achieve a large enough dust and the need to clean or replace the filter resistance is called the final resistance.
Dust holding capacity of the filter
In the rated air flow, the resistance of the filter to reach the final resistance, the total mass of dust contained in the filter is called the dust-tolerant.
Choose the principle
According to the specific circumstances of a reasonable choice of air filters, the selection principle is as follows:
1. Determine the efficiency of the last-stage air filter according to the cleanliness and purification standards required by the interior, and properly select the combination of air filters and the efficiency at all levels. If the indoor requirements of general purification, you can use the early effect of the filter; such as the indoor requirements of medium-sized purification, should be used in the first and second-level filter; if the indoor requirements of ultra-clean, it should be used in the first effect, efficiency and efficiency Level purification filter, and should reasonably properly match the efficiency of the filter at all levels, if the two adjacent filter efficiency difference is too large, the filter on the former level will not be able to play a protective effect on the filter after the level.
Correct determination of outdoor air dust content and dust characteristics. Because the filter is to filter outdoor air into the room after the filter, so the outdoor air dust content is a very important data. Especially in the multi-stage purification filter processing, select the pre-filter to use the environment, spare parts costs, operating energy consumption, maintenance and delivery and other factors considered after the decision.
3. Correct filter characteristics. The main characteristics of the filter efficiency filtration, resistance, penetration, dust holding capacity, filtration speed and air flow and so on. Where conditions allow, should be used as far as possible, high efficiency, low resistance, large dust holding capacity, medium filtration speed, air volume handling, manufacture and installation of convenient, low price filters. This is an economic analysis that takes into account both the one-time investment and the second-time investment and the energy efficiency ratio when choosing the air filter.
4. Analysis of the nature of dusty gas. The nature of the dusty gas associated with the selection of an air filter is primarily the temperature, humidity, amount of acid and alkali and organic solvents. Because some filters allow the use of high temperature, and some filters can only work under normal temperature and humidity, and dust-containing gas containing acid and organic solvents on the air filter performance and efficiency have an impact.
