Cyclone filtering integrated purifier

Technical Field

The utility model relates to an air purification field that industrial dedusting, more specifically say, relate to a whirlwind filters integral type clarifier.

Background

Cyclone dust collectors are a type of dust removing device. The dust removing mechanism is that the dust-containing airflow makes a rotary motion, the dust particles are separated from the airflow by means of centrifugal force and collected on the wall of the device, and then the dust particles fall into the dust hopper by means of gravity. Each part of the cyclone dust collector has a certain size proportion, and the change of each proportion relation can influence the efficiency and the pressure loss of the cyclone dust collector, wherein the diameter of the dust collector, the size of an air inlet and the diameter of an exhaust pipe are main influencing factors. In use, it should be noted that when a certain limit is exceeded, the favorable factors can also translate into unfavorable factors. Further, some factors are advantageous for improving the dust removal efficiency, but increase the pressure loss, and thus adjustment of each factor must be compatible.

Cyclone dust collectors have a simple structure, are easy to manufacture, install and maintain, have low equipment investment and operation cost, and are widely used for separating solid and liquid particles from gas flow or separating solid particles from liquid. Under normal operating conditions, the centrifugal forces acting on the particles are 5 to 2500 times greater than gravity, so the efficiency of the cyclone is significantly higher than that of a gravity settling chamber. Among the mechanical dust collectors, a cyclone dust collector is the most efficient one. It is suitable for removing non-viscous and non-fibrous dust, and is mostly used for removing particles with the particle size of more than 5 micrometers, and the parallel multi-pipe cyclone dust collector device also has the dust removal efficiency of 80-85% for the particles with the particle size of 3 micrometers. The pressure loss control range of the cyclone dust collector is generally 500-2000 Pa from the aspects of technology and economy. Therefore, it belongs to a medium-efficiency dust remover.
