How to increase the filtration efficiency of stainless steel filter element? Now our daily life and industrial production in the use of filter equipment is a lot of variety, for their performance we can not fully understand, so one one to see it! Today we take the stainless steel filter as an example, and we explain their basic knowledge! 1. Filtration efficiency the ratio of the amount of dust effectively captured by a filter to the amount of dust that is not filtered out is called“Filtration efficiency”. Generally, particles smaller than 0.1 mm are mainly in the movement of diffusion, the smaller the particle, the more efficient the filter; larger than 0.5 mm particles are mainly inertial motion, the larger the particle, the more efficient the filter. Second, running resistance when the air through the equipment will produce a small resistance, the sum of countless resistance is the resistance of the filter, resistance will increase with the increase of air flow and constantly increase, we can increase the filter material filter material area to reduce the relative wind speed through the filter material, reduce the operation of resistance. Third, the dynamic performance of captured dust will have a certain amount of additional resistance to the airflow, so in the process of using the filter resistance will continue to increase, and the captured dust will form new obstacles, reduce some of the filtration resistance.
Fourth, the service life of equipment filter material when more and more dust when its resistance is greater, when the resistance value exceeds the preset range, the life of the filter is over. If the filter material used by the equipment has static electricity or static electricity in the dust, it will have a more obvious effect on the improvement of the filtering effect, static electricity can make the dust change the trajectory of movement and hit the obstacles, accelerate the speed of adsorption. Six, dust capacity under specific test conditions, the filter can hold the weight of dust called dust capacity, and here said“Specific” refers to: 1, the standard test wind tunnel and its measurement equipment; 2. “Road dust” larger than the actual atmospheric dust particles; 3. Test method and calculation method specified in the test standard; 4. Conditions for termination of the test specified in the test standard. These are the basic knowledge we introduce about stainless steel filter, the article is from http://www.huanagl. com/, reproduced please indicate the source.
