Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] The method for cooling and quenching granulation of high-temperature carbide slag comprises the following steps:

[0028] Step 1: The carbide slag with a temperature of >1700°C is discharged from the carbonization furnace, and after passing through the slag ditch, the carbide slag can enter the water slag ditch in a parabolic form at a temperature point of >1650°C. The preferred implementation of the slag ditch is as follows: the length of the slag ditch is ≤1.5m and the slope is >20°. 50°C, its cross-sectional structure is as figure 2 shown. In the present invention, by designing a reasonable form of the slag ditch, the high-temperature slag can enter the punching point at a reasonable angle, timing and time, and can fully and quickly contact with the punching water to realize self-granulation.

[0029] Step 2: Transport the brewing water to...

Abstract

The invention relates to a method for cooling and quenching granulation of high-temperature carbide slag and a production device for cooling and quenching granulation of high-temperature carbide slag, belonging to the technical field of high-temperature furnace slag cooling and quenching granulation. The present invention carries out reasonable design on the aspects of slag groove type at carbonization furnace outlet, water slag groove type, water quenching ratio, water quenching pressure, water quenching flow control, water quenching control point, water quenching timing and water quenching time, etc. Realize rapid contact between carbide slag and cooling water, use the physical heat energy of carbide slag to realize self-granulation, and ensure the performance of high-temperature carbide slag after cooling, quenching and granulation to meet the subsequent low-temperature chlorination to produce TiCl 4 At the same time, safe and environmentally friendly production is realized, the performance of carbide slag changes little, and energy is saved.

Description

technical field [0001] The invention relates to a method for cooling and quenching granulation of high-temperature carbide slag and a production device for cooling and quenching granulation of high-temperature carbide slag, belonging to the technical field of high-temperature furnace slag cooling and quenching granulation. Background technique [0002] About 50% of the Ti resources in the vanadium-titanium magnetite in Panxi area entered the blast furnace slag. In order to improve the comprehensive utilization rate of titanium resources in the traditional blast furnace smelting vanadium-titanium magnetite process, Panzhihua Iron and Steel independently developed a new technology for extracting titanium from blast furnace slag. Technology, production of titanium dioxide chloride method. High-temperature carbide slag is a process product produced by smelting high-titanium-type blast furnace slag through a carbonization furnace. Efficient, environmentally friendly, and economic...
