INCREASE OF AIR DEDUSTING EFFECTIVENESS IN FUNCTIONAL ZONES OF METAL- AND WOODWORKING PRODUCTIONS

Abstract

A new cyclone apparatus enable to control the part specifications depending on the dust environment properties and characteristics is designed. This leads to the increase of the processing off-gas collection efficiency. The experimental study is resulted, and the geometrics of the diversiform cyclonic devices is related to the dedusting effectiveness. It is shown that the dedusting efficiency is higher in the inverted-cone cyclones (ICC) than in the cylinder devices. The ICC optimal design factors (the immersion depth of an exhaust branch pipe, and the cyclone working part/bunker volume ratio) raising the dust cleaning degree are found. The ICC with controlled parameters and with the gravity-discharge bin is offered. The developed ICC allows the considerable efficiency increase of the preliminary air cleaning from the metal- and woodworking production dust.
