Environment-friendly automatic fly ash storage and transportation and fine separation system

Abstract

A disclosed environment-friendly automatic fly ash storage, transportation and fine separation system comprises a bottom plate, a first pole plate, a second pole plate, a material disc and a second motor, negative charges are added to the first pole plate, positive charges are added to the second pole plate, and therefore a vertically-upward electrostatic field is formed between the first pole plate and the second pole plate; when a charging tray containing fly ash moves to a channel right facing a channel formed by the four baffles, the fly ash moves upwards under the action of an electrostatic field, fly ash particles are effectively prevented from scattering around by adding positive charges on the baffles, meanwhile, the fly ash particles are not attached to the baffles, a laser generator is further used for emitting transverse laser beams; when a laser beam irradiates on fly ash particles, light pressure in the horizontal direction can be generated, so that fly ash moves in the irradiation direction of the laser beam, the fly ash falls into the material collecting box, an operator further carries out static electricity elimination on the material disc for use in next sorting, and operation is easy.

Description

technical field [0001] The invention relates to a sorting device, in particular to an environment-friendly automatic fly ash storage and transportation and fine sorting system. Background technique [0002] Fly ash is a tiny ash particle discharged during fuel combustion, and its particle size is generally between 1 and 100 μm, also known as fly ash or soot. Fine solid particles in the flue gas ash produced by fuel combustion. Such as fine ash collected from flue gases in coal-fired power plants. Fly ash is formed when coal powder enters the furnace at 1300-1500°C, undergoes heat absorption by the hot surface under suspension combustion conditions, and then cools down. Due to the effect of surface tension, most of the fly ash is spherical, with smooth surface and small micropores. Part of them are cohered due to collision with each other in the molten state, and become honeycomb composite particles with rough surface and many corners. The chemical composition of fly ash ...

AI Technical Summary

Problems solved by technology

If a large amount of fly ash is not controlled or treated, it will cause air pollution, and if it enters the water, it will silt up the river, and some of the chemical substances will cause harm to organisms and humans.
