Energy-saving and environment-friendly process technical equipment for efficient scrap steel hopper filling and close-range dust collection

Abstract

The invention discloses energy-saving and environment-friendly process technical equipment for efficient scrap steel hopper filling and regional dust collection, and relates to the energy-saving and environment-friendly field of steelmaking process technologies of metallurgical enterprises. The energy-saving and environment-friendly process technical equipment comprises a scrap steel discharging dust collecting and processing area and a scrap steel hopper filling dust collection area, and is equipped with dust removal equipment, wherein the scrap steel discharging dust collecting and processing area is provided with a scrap steel discharging groove, a sieve, an ash leakage opening, a horizontal conveyor belt, an inclined conveyor belt and a refuse hopper; two capture hoods and corresponding dust-absorbing pipes are mounted on two sides above the scrap steel discharging groove; the scrap steel hopper filling dust collection area is provided with a main body framework of which the three peripheral sides are sealed, hopper filling tanks of which the upper peripheral side surfaces are sealed are uniformly mounted on the main body framework, and each of the hopper filling tank adopts the structure that air guiding sloped tubes with a plurality of holes formed in the inclined planes and air ducts are arranged on two sides of the upper opening; a scrap steel hopper is placed below each of the hopper filling tanks, and the scrap steel hoppers are placed on a flat truck with positioning blocks; the dust removal equipment and the pipeline through which the capture hoods in the two areas are connected are all provided with electric valves. The electric valves can be opened or closed as required to achieve the energy-saving and efficient dust removal purposes.

Description

[0001] technical field [0002] The invention relates to the field of energy saving and environmental protection of steelmaking process technology in metallurgical enterprises, in particular to a process technology equipment that can avoid repeated lifting and effectively eliminate post dust in scrap steel areas. Background technique [0003] In the metallurgical industry, most steelmaking plants have a steel scrap area. As the main raw material supply area of ​​the steelmaking plant, the scrap area is responsible for the technological process of unloading, storing and supplying out purchased and recycled scrap steel. It is the core of the steelmaking production process. An important link is also a serious and difficult-to-governance area where post dust is generated, and it is an important link that affects the quality and purity of smelted steel and causes energy waste. [0004] Reasons why it is difficult to manage: It is mainly determined by the three-dimensional space a...
