Description

Dust remover with coiled vortex pre-collection and fan blade cyclone air distribution

Technical Field

The utility model belongs to the technical field of dust collectors, and particularly relates to a dust collector with a coiled vortex pre-collection function and a fan blade vortex air distribution function.

Background

The pulse dust remover adopts a pulse blowing dust removal mode; the dust-removing device has the advantages of good dust-removing effect, high purification efficiency, large air quantity, long service life of the filter bag, small maintenance workload and safe and reliable operation, and is widely used for dust removal and purification of industrial dust in various industries such as metallurgy, building materials, machinery, chemical industry, mine and the like.

The load and efficiency of the filter bag are directly influenced by the dust content; the filter bag load in a local area is easily too high due to uneven air flow distribution, and the filter bag breakage rate is high due to air scouring; therefore, the dust content in the gas at the front end of the filter bag is reduced, the air flow is well distributed uniformly, and the dust removing device has a key effect on reducing the load of the cloth bag, improving the dust removing efficiency, preventing the filter bag from being damaged and prolonging the service life of the filter bag.

The common air intake mode of the pulse dust collector comprises a lower air intake mode and a side air intake mode. The lower air inlet mode has relatively simple structure and lower cost, and is a mode frequently adopted. However, during ash removal, the dust settling direction is opposite to the direction of the air inlet flow, which not only hinders the settling of the smoke dust, but also easily generates vortex and generates 'secondary dust raising'.

Based on the defects of the dust remover, the pre-collection and air-equalizing of the dust remover are realized by researching and utilizing the principles of the scroll vortex and the wind blade vortex, so that the resistance loss can be reduced, the load of a cloth bag is reduced, the dust removal efficiency is improved, the damage of the filter bag is prevented, the service life of the filter bag is prolonged, the energy consumption of a dust removal system can be reduced, and the operating cost is reduced.
