A comprehensive system for blast furnace slag collection and delivery and slag pool toxic water vapor pollution control

Abstract

The invention discloses a comprehensive system for taking and delivering blast furnace slag and controlling toxic water vapor pollution in a slag pond, which includes a slag flushing unit, a slag and water separation unit, a slag conveying unit and a water storage unit; the slag flushing unit includes a slag flushing ditch, slag, water The separation unit includes a slag and water separation unit, the slag conveying unit includes a slag delivery unit, and the water storage unit includes a clean water storage unit; the slag flushing ditch is connected to the slag and water separation unit, and the slag and water separation unit is respectively connected to the slag delivery unit and the clean water storage unit, The slag and water separation part transfers the separated slag to the slag conveying part, and the slag and water separation part transfers the separated water to the clean water storage part through the underground ditch; the clean water storage part is connected to the slag flushing ditch through the trench; the clean water storage part is equipped with barriers unit, the barrier unit limits the evaporation of toxic water vapor from the fresh water storage unit to the atmosphere. The invention is novel, practicable, feasible, efficient and energy-saving, and greatly reduces one-time investment and operation cost; it is applicable to both the existing advection process and the bottom filter process.

Description

technical field [0001] The invention relates to a comprehensive system for taking and delivering blast furnace slag and controlling toxic water vapor pollution in a slag pond, belonging to the technical field of environmental treatment. Background technique [0002] At present, blast furnace slag removal in steel mills is generally carried out in the slag removal pool by a driving slag removal machine, and the slag removal work is completed by a manually operated slag removal machine. From late autumn to early spring, steam is rising above the slag removal pond, and visibility is extremely low, making it very difficult for workers to operate and posing great safety hazards. Coupled with the toxicity and high temperature of water vapor, the operating environment for operators is very harsh. In addition, the slag obtained from the advection slag tank is often wet slag, which will spill a lot of poisonous water on the way to the cement plant, causing great pollution to the roa...

Problems solved by technology

[0014] Aiming at the deficiencies in the prior art, the present invention provides a comprehensive system for taking and delivering blast furnace slag and toxic water vapor pollution in the slag pool, which creatively changes the slag extraction in the pool to the slag extraction outside the pool, which solves the problem of picking up dry slag and also It creates conditions for the comprehensive and thorough treatment of toxic water vapor pollution in slag ponds. It is novel, practical, feasible, efficient, energy-saving, and greatly reduces one-time investment and operating costs; it is applicable to both the existing advection process and bottom filter process
