Abstract
The invention discloses a granulating device for molten steel or iron slag. The granulating device comprises a combined spray pipe composed of a reducing pipe and an increasing pipe, wherein the throat part of the combined spray pipe is provided with a molten slag pipe vertical to the axis of the throat part of the combined spray pipe, and cooling air flow exists in an outside space of the combined spray pipe and the molten slag pipe. Due to the adoption of the technical scheme, when flowing out of the pipe, molten steel or iron slag is impacted and cooled by high-speed air flow at the throat part to form granulated slag, and the granulated slag sprayed through the spray pipe is mixed with the outside cooling air flow and further cooled so as to be rapidly solidified.
Description
Technical field
The present invention relates to a kind of liquid steel slag of iron and steel smelting generation or the granulating device of scum.
Background technology
The slag that domestic steel industry iron and steel smelting produces or ironmaking scum treatment process mainly contain: the vexed efflorescence technology of slag heat, drum process are processed liquid slag technology, the pure technology of slag wind, HK method slag particle system etc.
In actual industrial production, also there are a lot of problems in the granulation of slag or scum and waste heat recovery, and the amount of heat that causes slag and scum to carry is not fully used.Rafael nozzle, Venturi tube or other are simple in structure by the characteristics of the combination spray pipe that reducing pipe and increaser consist of; realize easily and be convenient to arranging, and utilize its throat's high velocity air that the method that slag or scum carry out granulation and cooling is not also related in the actual production technology.
Summary of the invention
The problem to be solved in the present invention is slag or the scum granulation problem that produces for traditional iron and steel smelting, provides a kind of simple in structure, is convenient to arrange and the liquid steel slag that uses or the granulating device of scum.
For achieving the above object, the present invention has adopted following technical scheme:
The granulating device of a kind of liquid steel slag or scum; comprise the combination spray pipe that is consisted of by reducing pipe and increaser; be furnished with the slag pipeline perpendicular to the laryngeal axes of combination spray pipe at the throat of combination spray pipe place, described combination spray pipe and slag pipeline external space have cooling draught.
When molten steel slag or scum flow out in the pipeline, through impact and the cooling of throat's high velocity air, form grain slag.
Below be the present invention to the further optimization of such scheme:
Combination spray pipe is made of reducing pipe and increaser Rafael nozzle or Venturi tube or other.
Further optimize: the decoration form of described slag pipeline on throat's perisporium of combination spray pipe is one or more.
Further optimize: when the slag pipeline was even number, many slag pipelines were symmetrical arranged with the medullary ray perpendicular to laryngeal axes; When the slag pipeline is odd number and during more than, wherein one is positioned at the central position and perpendicular to the laryngeal axes setting, other slag pipeline is symmetrical arranged centered by a slag pipeline that is positioned at the center perpendicular to laryngeal axes.
The present invention adopts such scheme, when molten steel slag or scum flow out in the pipeline, through impact and the cooling of throat's high velocity air, forms grain slag, mixes with the exterior cooling air-flow through the grain slag of jet pipe ejection, and further the cooling makes its rapid curing.
The present invention is simple in structure, be convenient to arrange and use, and the slag of gained or scum particle diameter is smaller and even.This method will provide a kind of new solution thinking for granulation and the waste heat recovery problem of slag or scum, be conducive to it and be utilized more fully in steel industry.Therefore, the method has preferably application prospect.
The invention will be further described below in conjunction with drawings and Examples.

Embodiment
Embodiment; as shown in Figure 1; the granulating device of a kind of liquid steel slag or scum; comprise the combination spray pipe 1 that is consisted of by reducing pipe and increaser; be furnished with the slag pipeline 2 perpendicular to the laryngeal axes of combination spray pipe 1 at the throat of combination spray pipe 1 place, described combination spray pipe 1 and slag pipeline 2 space outerpaces have cooling draught.
When molten steel slag or scum flow out in the pipeline, through impact and the cooling of throat's high velocity air, form grain slag, mixes with the exterior cooling air-flow through the grain slag of jet pipe ejection, the further cooling makes its rapid curing.
In above-described embodiment, as shown in Figure 2, combination spray pipe can also be made of Venturi tube 3.
In above-described embodiment, as shown in Figure 3, combination spray pipe can also be made of Rafael nozzle 4.
In above-described embodiment, the decoration form of described slag pipeline 2 on throat's perisporium of combination spray pipe 1 is to arrange one or more.
As shown in Figure 4, when slag pipeline 2 was one, slag pipeline 2 was perpendicular to the laryngeal axes setting, and the lower end of slag pipeline 2 is communicated with the throat of combination spray pipe 1, top is communicated with slag ladle 5.
As shown in Figure 5, when slag pipeline 2 during for many and when the slag pipeline was even number, many slag pipelines were symmetrical arranged with the medullary ray perpendicular to laryngeal axes;
When the slag pipeline is odd number and during more than, wherein one is positioned at the central position and perpendicular to the laryngeal axes setting, other slag pipeline is symmetrical arranged centered by a slag pipeline that is positioned at the center perpendicular to laryngeal axes.
The present invention adopts such scheme, and the present invention is simple in structure, be convenient to arrange and use, and the slag of gained or scum particle diameter is smaller and even.This method will provide a kind of new solution thinking for granulation and the waste heat recovery problem of slag or scum, be conducive to it and be utilized more fully in steel industry.Therefore, the method has preferably application prospect.
