Steel slag ball production equipment and granulating system thereof

Abstract

The invention discloses steel slag ball production equipment and a granulating system thereof. The steel slag ball production equipment comprises the granulating system for spraying and cooling steel slag flowing out from a flowing groove by using high-pressure air water flow, wherein the granulating system comprises an air spraying mechanism and a cooling liquid spraying mechanism which are distributed up and down; the air spraying mechanism comprises an air compressor or a fan for supplying a high-pressure air source, and an air box for guiding air flow to be sprayed along a certain direction; the air box is provided with an air inlet and an air outlet; an air outlet of the air compressor or the fan is communicated with the air inlet of the air box through a pipeline; spraying panels are arranged at the front end of the air box; the spraying panels are provided with nozzles which are communicated with the air outlet of the air box; and more than two layers of spraying panels are arranged from top to bottom and each layer of spraying panel is horizontally provided with a plurality of nozzles in parallel. The granulating system of the steel slag ball production equipment adopts air and cooling liquid to commonly act on steel slag and the acting time in the air is long; the oxidization reaction is sufficient; the configuration of an organization is stable; and the granulating system can be used for grinding materials, building materials, water treatment, desulfurization agents and the like.

Description

technical field [0001] The invention relates to equipment for processing waste steel slag or high-temperature liquid steel slag into steel slag balls for industrial application. Background technique [0002] A large amount of steel slag will be produced in the metallurgical production process of converter or smelting furnace. For example, in the process of refining steel in converter, steel slag with high non-metal content will be produced. These steel slags must be gradually discharged from the furnace during smelting. According to the latest statistics, the amount of steel slag in my country was about 80 million tons in 2010, and the utilization rate of steel slag was only about 10%, which is still far from the goal of "zero" discharge of solid waste by Chinese enterprises. The discharge of a large amount of waste steel slag not only occupies a large amount of arable land, but also pollutes the environment. Therefore, the recycling of steel slag has become a social hot spo...

AI Technical Summary

Problems solved by technology

In this type of steel slag processing equipment in the prior art, the liquid steel slag flowing out of the launder lacks matching with the injection of high-speed water and air flow. In addition, the fluidity of the steel slag is poor and the distribution of the steel slag flow is uneven, resulting in incomplete granulation of the steel slag balls, spherical shape not good

In addition, the pools in the prior art can only take out the steel slag balls by digging after draining, which has low work efficiency, high labor intensity and serious waste of water resources, and the steel slag balls are easily eroded by harmful substances in the water during the accumulation process in the pool And reduce the quality of steel slag ball
