Blast furnace slag taking and conveying and slag pool toxic water vapor pollution treatment comprehensive system

Abstract

The invention discloses a blast furnace slag taking and conveying and slag pool toxic water vapor pollution treatment comprehensive system which comprises a slag flushing unit, a slag and water separating unit, a slag conveying unit and a water storing unit, wherein the slag flushing unit comprises a slag flushing trench; the slag and water separating unit comprises a slag and water separating part; the slag conveying unit comprises a furnace slag conveying part; the water storing unit comprises a clear water storing part; the slag flushing trench is connected with the slag and water separating part; the slag and water separating part is connected with the furnace slag conveying part and the clear water storing part; the slag and water separating part transfers the separated furnace slag to the furnace slag conveying part and transfers the separated water flow to the clear water storing part via a blind ditch; the clear water storing part is connected with the slag flushing trench viathe trench; the clear water storing part is provided with an obstructing unit; and the obstructing unit prevents toxic water vapor in the clear water storing part from evaporating to the atmosphere environment. The system is novel, practical, feasible, efficient and energy-saving, greatly reduces the one-time investment and operating cost, and is applicable to the existing streaming type technology and the bottom filtering type technology.

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
