Description
Technical field
The New-type Swirl Flow that the utility model relates to a kind of hot stove slag in ore deposit for the low iron-holder of shrend of the smelting industry pulp water pond of quenching.
Background technology
The molten state slag that the hot fire grate in ore deposit goes out generally is could use as material of construction through the slag granules that forms the normal temperature state after the shrend.Water quenching technology roughly can be divided into two classes, and a kind of is directly high temperature sludge to be poured in the stilling basin bubble pulp water to quench, and another kind is to use the shrend of high pressure water flushing cinder.
Dual mode relatively, the bubble pulp water mode of quenching has easy, safe advantage in operation, but need to adopt driving to grab slag, level of automation is low, big, the on-the-spot flue gas undiscipline of workman's labor capacity, objectionable impuritiess such as the phosphorus that contains in the flue gas, sulphur can cause detrimentally affect to environment, are the objects that will eliminate rectification from now on.
Under the flushing cinder shrend mode, be in specific water slag groove, to dash the melting slag liquid of quenching with high pressure water to form the grain slag mixture, flow into dewatering drum again and carry out the pulp water separation, can replace driving and grab slag realization automatization, and effective water vapor of slag generation of quenching of collecting, solved on-the-spot diffusing gas problem to a certain extent, workman's labor capacity is little.But also there is certain drawback, such as in the flushing cinder process, forming a large amount of glass fibre easily, handles for follow-up steam and bring very big detrimentally affect; The slag granules that flushing cinder forms is little, causes thin slag content height in the flushing cinder water, to the equipment pipe serious wear; The control process serious forgiveness is low, operates not easy; When power failure suddenly or water pump fault take place in the flushing cinder process of coming out of the stove, cause security incident easily.
Summary of the invention
The purpose of this utility model provides a kind of eddy flow Water Quenching Slag of utilizing, and takes into account the pulp water pond of quenching of the advantage of flushing cinder and bubble slag simultaneously.
The technical solution of the utility model is to realize like this, the eddy flow pulp water pond of quenching is cylindrical, eddy flow quench the sidewall setting in pulp water pond quench pulp water ingate, slag ingate, overflow weir, grain slag outlet opening, open the described pulp water ingate of quenching at described sidewall tangent line, two described, and the pulp water ingate of quenching becomes 180 angular distribution at described sidewall, and the slag ingate projects into 90 ° of angles with the pulp water ingate of quenching on same horizontal plane; The slag ingate is higher than overflow weir on described sidewall is vertical, and overflow weir is higher than the pulp water ingate of quenching, and the pulp water ingate of quenching is higher than the grain slag outlet opening; The grain slag outlet opening is provided with gate valve.
All right, the quench top in pulp water pond of eddy flow is provided with rupture disk.
All right, eddy flow is quenched and also is provided with the spilling water vapor outlet port hole of quenching on the sidewall in pulp water pond, is higher than overflow weir in the vertical up-quenching spilling water vapor outlet port hole of described sidewall.
All right, the eddy flow pulp water pond of quenching also comprises automatic control device, automatic control device can be controlled high pressure water and wash by water in the pulp water pond of quenching for eddy flow by the pulp water ingate of quenching, control slag feeding unit enters for the eddy flow pulp water pond of quenching by the slag ingate and advances slag, the unlatching of the gate valve of control grain slag outlet opening or close.
A kind of advantage that the utility model provides is, by adopting above-mentioned structure, high pressure water enters the eddy flow pulp water pond of quenching by the pulp water ingate of quenching from the tangential direction of sidewall, and in quenching the pulp water pond, eddy flow forms eddy flow, slag enters eddy flow by the slag ingate and quenches in the pulp water pond, carries out flushing cinder and bubble slag under the effect of eddy flow, and flows out the eddy flow pulp water pond of quenching by the grain slag outlet opening under the effect of eddy flow, quench pulp water pool inner water position when too high when eddy flow, and water can overflow from overflow weir.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Figure one the utility model structural representation.
Figure two the utility model top views.
Among the figure: sidewall 1, the pulp water ingate 2 of quenching, slag ingate 3, overflow weir 4, grain slag outlet opening 5, rupture disk 6, the spilling water vapor outlet port of quenching hole 7.
Embodiment
As shown in Figure 1 and Figure 2, the eddy flow pulp water pond of quenching is cylindrical, eddy flow quench sidewall 1 setting in pulp water pond quench pulp water ingate 2, slag ingate 3, overflow weir 4, grain slag outlet opening 5, the spilling water vapor outlet port of quenching hole 7, open the described pulp water ingate 2 of quenching at sidewall 1 tangent line, two described, and the pulp water ingate of quenching is angular distribution at 1 one-tenth of described sidewall 180, and slag ingate 3 projects into 90 ° of angles with the pulp water ingate 2 of quenching on same horizontal plane; Be higher than overflow weir 4 in sidewall 1 vertical up-quenching spilling water vapor outlet port hole 7, slag ingate 3 is higher than overflow weir 4, and overflow weir 4 is higher than the pulp water ingate 2 of quenching, and the pulp water ingate 2 of quenching is higher than grain slag outlet opening 5; Grain slag outlet opening 5 is provided with gate valve; The quench top in pulp water pond of eddy flow is provided with rupture disk 6, the eddy flow pulp water pond of quenching also comprises automatic control device 8, automatic control device 8 can be controlled high pressure water and wash by water in eddy flow is quenched the pulp water pond by the pulp water ingate 2 of quenching, control slag feeding unit enters eddy flow by slag ingate 3 and quenches and advance slag in the pulp water pond, the unlatching of the gate valve of control grain slag outlet opening 5 or close.
