Background
At present, cyclone dust removal technology is adopted in a plurality of pretreatment stages of a gas treatment process. Cyclone dust collectors are a type of dust collecting device, and the dust collecting mechanism is that a dust-containing airflow rotates, dust particles are separated from the airflow by means of centrifugal force and collected on the wall of the dust collector, and then the dust particles fall into an ash bucket by means of gravity.
However, the processing technology has the defects that:
the abrasion is serious, and particularly when high-concentration or high-abrasion dust is treated, the inlet and the cone part are easy to be worn out;
the dust removal efficiency is not high (the efficiency is low for collecting fine dust with the particle size less than 5um and dust with small dust particle density), and the requirement of the emission concentration of the dust-containing gas can not be met when the dust remover is used alone;
because the dust removal efficiency is reduced along with the increase of the diameter of the cylinder, the processing air volume of a single dust remover is limited to a certain extent.
