Dust treatment equipment

Abstract

The invention discloses dust treatment equipment. The equipment comprises a dust lead-in unit, a dust treatment unit, a gas emission unit and a control unit, wherein the dust lead-in unit and the dusttreatment unit are communicated with each other through an air inlet pipeline; the dust lead-in unit comprises an induced draft pipe, an induced draft fan, and a filtering screen arranged at the outlet of the induced draft fan; the dust treatment unit comprises a spraying unit performing spraying treatment on lead-in dust, and a retreatment unit performing retreatment on dust treated by the spraying unit; the gas emission unit comprises a dust concentration sensor for monitoring the concentration of dust in emitted gas, and an air outlet pipeline for emitting gas; the air outlet pipeline is communicated with the air inlet pipeline through a return pipe, so as to ensure that gas returns to the dust treatment unit. The dust treatment unit sequentially performs spraying treatment, dehumidification treatment and electrostatic dust collection treatment on gas containing dust, and is high in dust removal efficiency; the dust concentration sensors monitors the concentration of dust in the treated gas, and the dust emission load is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of environmental protection equipment, and in particular relates to a dust treatment equipment. Background technique [0002] Dust is one of the biggest hazards in ore mining operations. A large amount of dust can be generated during ore cutting, ore loading and unloading, and transportation. The harmfulness of dust is related to the degree of dispersion of dust and the composition of dust materials. , Respirable dust is the most harmful to people. The particle size of dust is measured by the diameter of the dust position, and the unit of micron is used. The particle size of mine dust is divided into three categories according to its visibility; visible dust particles can be seen by the inner eye when the light is bright; microscopic dust particles Visible under a normal microscope; ultra-microscopic dust particles can only be seen under a high-power or electron microscope. Mineral dust particle size is diff...

Problems solved by technology

[0003] At present, there is no good treatment device for dust pollutants. In places where dust gathers, workers wear masks to prevent dust from entering the mouth and other parts. This method is not conducive to the diffusion of dust in the environment, and masks are worn during work. , especially wearing a mask in summer is even more uncomfortable
