Embodiment

[0027] see figure 1 , 2 , the first position of the belt conveyor 1 is sealed with a sealed chamber 2, followed by a dust removal chamber 5, a dust-gas separation chamber 8 and a circulating dust reduction chamber 9 after the station of the drop pipe 3, and the upper part of each chamber is provided with an inclined folding plate 7, and the angle between the folding plate 7 and the horizontal direction is 15°-45°, and the chambers are connected into one body through the connector 10. First of all, for the rising dust gas falling into the dust removal chamber 5 from the discharge pipe 3, it is redirected by the inclined folding plate 7 on the top, causing turbulent flow and causing the large particles to settle; while the fine dust is transported by the belt conveyor 1 at the discharge port. And the movement of the material generates a slight negative pressure, so that the fine dust flows back to the lower end of the discharge pipe 3 through the return pipe 4, and finally most...

Abstract

The invention relates to a method of dust removal for a coke transportation system, belonging to the technical field of environment-friendly dry dust removal. The method of the invention comprises the following steps: sealing a conveying device for materials to pass through, and sequentially arranging a dust-removal chamber, a dust-gas separating chamber and a cyclic dust-settling chamber after the blanking station of a conveyor; generating turbulent flow to the uplifting dust-containing gas in the dust-removal chamber by an overhead tilted deflecting plate, so that large particles can be settled, and generating negative pressure to fine dust therein at the blanking opening, so that the fine dust can flow back to the lower end in a blanking tube; continuing to change the movement direction and movement velocity of the dust-containing gas flow by an overhead tilted deflecting plate in the dust-gas separating chamber, so that the fine dust can be separated from the gas flow; further reducing the kinetic energy of the dust by the overhead tilted deflecting plate and vertically suspended rubber strips in the cyclic dust-settling chamber, and generating static electricity on the rubber strips so that the remaining dust can be settled. The method of the invention has the advantages of small investment, no area coverage, high dust arrestment rate, low processing cost, long service life of dust removers and short construction period; and the outlet gas of the dust removers is lower than the national emission standards.

Description

technical field [0001] The invention relates to a dust removal method for a coke conveying system of an ironmaking enterprise, and belongs to the technical field of environmental protection dry dust removal. Background technique [0002] Most of the dust removal systems in my country's coke transportation process use negative pressure suction bag dust removal technology for dust removal. The bag dust removal process includes dust collection hoods, conveying pipes, bag filters, induced draft fans and chimneys, etc. [0003] Advantages: high dust removal efficiency. [0004] Disadvantages: large investment; low dust collection rate; horizontal pipes are easy to block, which affects the collection rate; large air volume and high operating costs; dust collectors, induced draft fans and chimneys occupy a large area; full-time operation and maintenance personnel are required. Dust transport equipment. Contents of the invention [0005] The technical problem to be solved by th...
