Basic Principle of High Efficiency Filter
Basic Principle of High Efficiency FilterHigh-efficiency air filter manufacturers briefly describe the basic principle of high-efficiency filters, the basic principle of high-efficiency filters is the use of partition and no partition in two ways, according to the direction of the movement of dust-containing airflow is divided into the side of the eye into the air, under the air intake of two kinds. It is usually composed of a clean air chamber, middle box, ash hopper, frame, and pulse-blowing installation. When the dusty airflow enters the high-efficiency filter from the lower part of the box, due to the sudden expansion of the cross sectional area of the airflow, the flow rate is reduced, a part of the large particles in the airflow, dust and cohesive dust particles of large density under the action of centripetal force and gravity along the wall of the cylinder spinning down the ash hopper; the fine particle size, density of small particles of dust suspended in the gas through the airflow dispersal installation, and then enter into the filter room in the average dispersion of the filter bags in the gap, through the high-efficiency filter. The inertial collision of the exterior, sieve filter, and other roles pile up in the exterior of the high-efficiency filter. High-efficiency air filter manufacturersHigh-efficiency air filter manufacturers of high-efficiency filter cleaning and maintenance requirements: with the dust attached to the surface of the high-efficiency air filter from time to time, the dust layer thickens from time to time, and the resistance value of the high-efficiency filter increases; when the resistance value of the high-efficiency filter arrives at a certain value, the pulse dust controller issues a directive to control the opening of the pulse valve, and the high pressure air in the gas bag flows through the pulse valve to the small holes on the blowtorch and radiates a high-speed high-pressure venturi to the small holes on the venturi. The venturi radiates a high-speed and high-pressure induced airflow, constituting an induced airflow equivalent to several times the volume of the induced airflow, and the dust outside the high-efficiency filter falls from the outside of the bag under the action of mechanical force and falls into the ash hopper, arriving at the purpose of clearing the dust; when the high-efficiency filter resistance falls to the lower limit, the clearing mechanism suspends the work and maintains the continuity of work of the dust collector. High-efficiency air filter manufacturers How to reduce impurities in the air: as the key issue of high-efficiency filters - high-efficiency filter material quality, there are breakthroughs today, the use of life expectancy is generally more than 1 year, and in practice, there have been up to 2-to 3 years of performance. Cleaning of high-efficiency filters. Cleaning: High-frequency vibration is used to clean the larger dust particles that enter the exterior of the filter bag as much as possible, without affecting the fastness of fiber entanglement, and insisting on the good peeling resistance of the filter bag. In dry and semi-dry desulphurization systems, there is a further reduction of air impurities. |
