Cleaning shaft 3 on be arranged in parallel scrubbing tower 5 and bagroom 4, with use two kinds of water cooling and air cooling method (i.e. air cooling method)
Mode is handled a variety of hot splashing steel slags (such as desulfurization slag, vessel slag, electroslag and refining slag etc.), i.e.,：It can either pass through
Spraying water process free calcium oxide and the high slag of content of magnesia, the humid flue gas in processing procedure is handled by scrubbing tower 5,
To reach discharge standard；Also the reducing slag that can not be fetched water, refining slag can be handled, and coordinates loading machine 14 to turn over slag, both accelerates steel
Slag is cooled down, and the lime of efflorescence is stirred, and is collected by bagroom 4, is realized zero-emission, improves the recovery effect of metal in the dreg
Rate；The present invention is suitable to handle various slags, solves the problems, such as that flue gas and moisture contamination are big, energy-conserving and environment-protective, investment reduction, is applicable
Scope is wide, has the bigger performance of enterprises and social benefit compared with prior art.
2nd, the top of bold and vigorous slag chute 2 of the invention sets smoke collecting cover 24, and smoke collecting cover 24 is arranged into cone-shaped, together
When combine blower fan 6 exhausting carried out in slag chute 2 to sprinkling, it be subnormal ambient to make in smoke collecting cover 24, beneficial to collection dust, flue dust,
Waste gas etc., operating efficiency is high, high treating effect.
The 3rd, grid 28 is set on the top surface in bold and vigorous slag chute 2 of the invention, multiple sprinkler tips 29 are set on grid 28,
To realize spray water operation, the cooling effectiveness of hot splashing steel slag is improved, slag pulverization rate is improved, is advantageous to slag sluicing system；Meanwhile sprinkle
The inside front of the fire resisting door 23 of slag chute 2 sets a row to bore aerial fog nozzle 27 entirely, to carry out aerosol dust suppression, by boring aerosol to complete
The water and compressed air of certain pressure are passed through in nozzle 27, to form full cone water smoke, reaches powder when suppressing to turn over slag and slag tap
Dirt, water consumption is few, and quick-fried splash will not occur in warm sludge.
4th, bold and vigorous slag chute 2 of the invention can form enclosed environment by closing fire resisting door 23, can effectively suppress poisonous and harmful
The spilling of flue gas and waste gas, prevents dust and exhaust emission, realizes cleaner production, conservation of nature environment；Simultaneously by bold and vigorous slag
Groove 2 can also carry out turning over slag operation in factory building 1, both improved work effect by loading machine 14 to sprinkling the slag in slag chute 2
Rate, the discharge of dust is reduced again, reduce the harm to equipment such as dust, reduce equipment protection grade, be advantageous to save equipment
Investment, system failure rate is reduced, protects working environment.
