Problems solved by technology

[0003] The way of comprehensive utilization of fly ash has been developed from road construction, dam construction, project backfill, mortar and soil transformation in the past to the present in cement raw materials, cement admixtures, large-scale water conservancy projects, large-volume concrete products, and advanced fillers. Advanced utilization and other fields, but generally speaking, it is still a problem of insufficient advanced applicable technology and low utilization rate of high added value

Embodiment Construction

[0027] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0028] Such as Figures 2 to 5 As shown, the device includes an air jet pipeline, a discharge pipe, a dust cover, a triangular storage chamber, a louvered channel, a stepped pipeline, and a suction pipe. The air jet pipeline is composed of spoiler pipe 2 and intake pipe 1. The elbow end of spoiler pipe 2 is welded on the channel reserved by the pipe body of suction pipe 21, and the pipe body of spoiler pipe 2 passes through suction pipe 21. Stretch into the stepped pipeline, and extend into the dustproof cover 12 along the center line of the stepped pipeline. The spoiler tube 2 is welded to the lower end of the suspension chamber 14 through a cross-shaped spoiler tube fixing frame 13 , and the disturbed air outlet is slightly higher than the bottom of the dust cover 12 .

[0029] One end of the inlet pipe 1 is connected to the air outlet pipe of the air comp...

Abstract

The invention discloses a coal ash collecting fractionation device which comprises an air flow spraying pipeline, a discharge pipe, a dust guard cover, a material storage chamber, a blind window, a multi-step type pipeline and a suction pipe. Firstly, the air flow enters the coal ash collecting fractionation device through the spraying pipeline to stir coal ash to be in a fluidization state. Then, the fluidified coal ash is sucked into the multi-step type pipeline, the flow speed in the pipeline is reduced progressively, and coal ash particles with large density or particle sizes suspend in a suspension chamber or subside near the pipeline wall inside a setting chamber. The set coal ash is collected in the material chamber through the blind window, and the set coal ash can be drawn out slowly. After the operation is carried out, the particles with different density or particle sizes in the coal ash are collected and separated.

Description

technical field [0001] The invention relates to the field of particle material collection, classification and separation in the fields of industry, environmental protection, etc., and more specifically relates to a fly ash collection, classification and separation device. Background technique [0002] The comprehensive utilization of bulk industrial waste is the fundamental solution to the environmental pollution and safety hazards caused by the accumulation of industrial solid waste. Fly ash is one of the bulk industrial wastes produced by thermal power generation. Its emissions are huge. In addition to dust pollution in the general sense, it also contains trace amounts of heavy metals and extremely small amounts of radioactive substances. It is harmful to water and soil. It also brings serious pollution and is prone to geological disasters. [0003] The way of comprehensive utilization of fly ash has been developed from road construction, dam construction, project backfil...
