Method and system for environmental governance of closed stock yard

Abstract

The invention relates to a method and system for environment governance of a closed stock yard. The method comprises the steps: collecting and purifying flying dust generated during the operation of a stacker-reclaimer in real time through a mobile dust removal station; conducting spray dust suppression on a material pile through a movable spray dust suppression system, and humidifying and settling dust particles suspended in the air; and performing partitioned forced ventilation and dust removal on the closed raw stock yard through a partitioned dust removal system, reducing the concentration of suspended dust, collecting dust in air to a dust removal header pipe, and discharging purified gas to the air. According to the method and system, the problems of dust diffusion, pollution and the like in the stock yard in the prior art are solved, the technical means of spray dust suppression, local dust removal, comprehensive ventilation and the like are fully utilized, the synergistic effect is formed, comprehensive environment governance of the closed stock yard is achieved, the environment quality is improved, and safe production is guaranteed.

Description

technical field [0001] The invention relates to the technical field of environmental treatment of iron and steel raw material yards, in particular to a method and system for environmental treatment of closed raw material yards. Background technique [0002] The raw material yard of a large iron and steel enterprise is a place for receiving, storing, sizing, mixing and transporting raw materials and fuels. The raw material field has a large amount of material to handle and covers a large area. The early raw material field was mostly open-air, and the bulk materials stored in the wind and sun would not only cause material loss, but also pollute the environment. With the enhancement of people's awareness of environmental protection , the requirements of environmental protection policies are becoming increasingly stringent. At present, most iron and steel enterprises have closed their raw material yards. [0003] After the open-air material yard is closed, the ventilation condi...
