Diffusion Cyclone has a small cone large, the bottom reflective screen, high dust removal efficiency, simple structure and moderate pressure loss and so on. Suitable for trapping dry, non-fibrous particles of dust. First, the structural characteristics: diffusion Cyclone biggest difference with the general cyclone there are two; 1, having an inverted cone shape; 2, at the bottom of the cone is equipped with reflective screen, inverted cone has gradually increased distance from the center of the large cone, reduce dust and gas from the center of the cone to the role of short-circuiting the exhaust pipe possibilities. Reflective screen allows the dust has been separated along the ring between cone and reflective screen fall into the hopper seam and prevent the rise of a purge gas to the fine dust rolled away, thereby improving collection efficiency. Another feature of this device is to have a large hopper, due to the small amount of gas entrained dust from the bottom of the cone rotating into the ash bucket, ash bucket cylinder diameter generally take 1.65 times the diameter of the cylinder, the height of the ash surface portion of space Take cylinder diameter of 1 times. Second, the principle: Diffusion-type cyclone dust gas works through a rectangular inlet duct tangentially into the filter cartridge, dust in the role of trying to separate from the wall, and rotated downward move with the flow, large part of the flow of love reflection, rotation rise through the exhaust pipe, a small part of the air with dust through the annulus between the reflective screen and the cone into the hopper, the hopper into the gas velocity is lowered, due to inertia, the dust falls within the hopper discharge from the cinder valve, the gas is increased by the reflective screen vents to exhaust pipe. Third, the collection efficiency; (1) gas inlet gas dust concentration and removal efficiency of the relationship; talc as a sample, respectively, in volume of 300m3 / h, pressure loss 350-370Pa and gas to 600m3 / h, pressure Under the conditions of loss of 1500Pa air inlet dust concentration in the 1.7-200g / m3 range, pressure loss at 350Pa or more, stable collection efficiency. (2) the relationship between the intake inlet velocity and dust removal efficiency; with imported gas velocity increases collection efficiency increased slightly, while imports of gas velocity after Canada, dust dynamic pressure loss increases greatly, therefore, with the increase of imported gas velocity to improve the collection efficiency of the approach is not desirable. Fourth, the proliferation Cyclone collection efficiency rating grade collection efficiency% (by mass percent) dust particle size <5um 90% removal efficiency classification (in percentage by mass) of dust size 40-60um 99 dust particle dust size 5-10um 94 Path> 60um 100 dust particle dust size 10-20um 95 20-40um 98% of the total collection efficiency of 96.4 Order Tel; 15133729888 Website; http; // www.hbbtcc.com
