Description

Energy-saving dust exhausting fan

Technical Field

The utility model relates to a dust removal technical field specifically is an energy-saving dust exhausting fan.

Background

In recent years, with rapid development of economy, metallurgical steelmaking electric furnaces and raw coal-fired boilers have increased, and the atmospheric pollutants discharged from these furnaces pose great harm to the surrounding environment, so that a technology for removing particulate matters from dust-containing gas to reduce the emission thereof to the atmosphere has become more and more important. The trapping mechanism can be classified into a mechanical dust collector, an electric dust collector, a filtering dust collector, a washing dust collector and the like. The mechanical dust remover removes dust particles from the airflow by means of mechanical force, and has the advantages of simple structure, low equipment cost and operation cost, but low dust removal efficiency. The electrostatic precipitator utilizes electrostatic force to separate dust particles from air flow, and is usually classified according to plate type and tube type, and is characterized by small air flow resistance, high dust removal efficiency up to more than 99%, but high investment. The occupied area is large. The filter dust collector enables dust-containing gas to flow through the filter material to separate and collect dust particles, and adopts two modes of internal filtering and surface filtering, so that the dust collection efficiency is generally 90-99%, and the filter dust collector is not suitable for dust-containing gas with high temperature. The washing dust remover washes dust-containing gas by liquid, so that dust particles collide with liquid drops or liquid films to be captured and are separated from gas flow, the dust removal efficiency is 80-95%, and the operation cost is high. In order to improve the efficiency of trapping particles, new dust collectors integrating several dust removal mechanisms, such as a charged bag filter, a charged droplet scrubber, and the like, are being developed.
