Description

Multistage cyclone dust collector device

Technical Field

The utility model belongs to the technical field of the environmental protection, a treatment facility after rubbish burning is related to, in particular to multistage cyclone device.

Background

The garbage incinerator has the advantages that due to the fact that feeding types are complex, impurities are many, the heat value is low, the temperature of the incinerator is low, part of combustible objects are not combusted in a hearth, but are combusted at the tail part, or combustible objects and large particles reach the tail part of the garbage incinerator, the dust removal pressure of other fine dust removal equipment at the tail part is large, and the damage condition and the dust removal effect of other equipment are not obvious. The cyclone dust collector separates dust particles from the airflow by means of centrifugal force and collects the dust particles on the wall of the cyclone dust collector, and the dust particles fall into the dust chamber by means of gravity. The dust remover is mainly used for pre-removing dust or removing large-particle dust generally, and has lower dust removing efficiency on small-particle dust; the cyclone afterbody cooperates other dust collecting equipment to handle the tiny particle after the cooling again, finally reaches emission after the qualified standard, because rubbish impurity is many, and the kind is numerous and diverse, the barrel diameter and the central section of thick bamboo diameter of calculating cyclone often select inaccurately, when the barrel diameter undersize, the wall is too close with the blast pipe, the particle escapes again easily, the barrel diameter is too big, take up an area of big not arranging, the velocity of flow reduces centrifugal force and reduces, dust collection efficiency hangs down, the particle major diameter part discharges the afterbody.
