Abstract
The invention relates to a red mud stockyard endless tube, especially to a structure for protecting the red mud stockyard endless tube in Bayer process production under the condition that red mud is discharged by semi-dry process and conveying pressure is high. The structure comprises a red mud stockyard, a red mud endless tube arranged on a red mud dam of the red mud stockyard, and a red mud main tube connected with the red mud endless tube, wherein the red mud main tube is connected with one end of a red mud branch tube before the red mud main tube enters the red mud stockyard and the red mud endless tube; the other end of the red mud branch tube is arranged in the red mud stockyard and provided with explosion sheets. The present invention has the advantages that the red mud main tube is provided with the red mud branch tube and then guided to the red mud stockyard and the explosion sheets are provided on the red mud branch tube, thereby protecting the red mud endless tube and valves of relatively low pressure in the red mud stockyard.
Description
Technical field
The present invention relates to a kind of red mud dump endless tube, relate in particular to a kind of in Bayer method is produced, red mud adopt semidry method to efflux and the discharge pressure condition with higher under the structure of protection red mud dump endless tube.
Background technique
In the alumina factory that adopts Bayer method to produce, the big more options semidry method of red mud effluxes, and effluxes the red mud solid content and is about 45～50%, and this red mud that contains admittedly is the non-Newtonianism fluid, and in course of conveying, drag losses is big; And red mud dump generally is located at outside the alumina factory, and the distance between alumina factory and the red mud dump is generally far away.For above-mentioned reasons, the pressure of Bayer process red mud semidry method efflux pump is generally higher, according to the distance that effluxes distance, effluxes pressure and does not wait to tens of MPas from several MPas.And the endless tube pressure that is located at red mud dump be located at the pipeline pressure that red mud effluxes on the pipe network and compare much lower, because the discharge pressure of red mud decay gradually under the normal condition along with the prolongation of pipeline, to the red mud dump place, general pressure is lower, from saving the angle of investment, being located at the endless tube of red mud dump and valve pressure, generally to compare the pipeline pressure that effluxes on the pipe network low.But unusual when produce occurring, as causing the whole system pressure that effluxes when raising because of effluxing reasons such as line clogging or efflux pump operation irregularity, the endless tube and the valve that are located at red mud dump are low because of pressure, just damage easily, thereby production is impacted.
Summary of the invention
The present invention is exactly a kind of structure of protecting Bayer process red mud stockyard endless tube that provides in order to solve the problems of the technologies described above; purpose is to solve when the red mud semidry method effluxes; during the improper rising of heat-extraction system pressure outside, the destruction that the relatively low stockyard endless tube of pressure and valve are caused.
For reaching above-mentioned purpose, the present invention is achieved through the following technical solutions:
The structure of protection Bayer process red mud stockyard endless tube; comprise red mud dump; the red mud endless tube that on red mud dump red mud dam, is provided with; the red mud main line that is connected with the red mud endless tube; before entering red mud dump and red mud endless tube, be connected on the described red mud main line with an end of red mud arm; the other end of red mud arm is located in the red mud dump, is provided with rupture disk in the other end red mud dump of red mud arm.
Described rupture disk Initiation Pressure will be lower than the design pressure of red mud dump endless tube.
Be provided with valve between described red mud dump and the red mud endless tube.
Advantageous effect of the present invention: introduce red mud dump again by on the red mud main line, establishing the red mud arm, and on the red mud arm, establish rupture disk, thereby realize the endless tube that pressure on the protection red mud dump is relatively low and the purpose of valve.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: 1, red mud dump; 2, red mud endless tube; 3, valve; 4, red mud main line; 5, red mud arm; 6, rupture disk.
Embodiment
Below embodiments of the invention are described in detail in conjunction with the accompanying drawings, but protection scope of the present invention is not limit by embodiment.
As shown in Figure 1; the present invention protects the structure of Bayer process red mud stockyard endless tube; comprise red mud dump 1; the red mud endless tube 2 that on red mud dump 1 red mud dam, is provided with; the red mud main line 4 that is connected with red mud endless tube 2; before entering red mud dump 1 and red mud endless tube 2, be connected on the red mud main line 4 with an end of red mud arm 5; the other end of red mud arm 5 is located in the red mud dump 1; in the other end red mud dump 1 of red mud arm 5, be provided with rupture disk 6; rupture disk 6 Initiation Pressure will be lower than the design pressure of red mud endless tube 2; so long as that Initiation Pressure is lower than the design pressure of red mud endless tube 2 is just passable, be provided with valve 3 between red mud dump 1 and the red mud endless tube 2.
Working principle of the present invention: in the Bayer method alumina factory; red mud adopts semidry method to efflux and efflux pressure when higher; the pressure release of at first detonating of rupture disk on the red mud arm; material in the red mud main line 4 is discharged in the red mud dump 1 via red mud arm 5, thereby has protected relatively low red mud endless tube 2 of pressure and valve 3.
Claims (3)
1. protect the structure of Bayer process red mud stockyard endless tube; comprise red mud dump; the red mud endless tube that on red mud dump red mud dam, is provided with; the red mud main line that is connected with the red mud endless tube; it is characterized in that on the described red mud main line before entering red mud dump and red mud endless tube, being connected with an end of red mud arm; the other end of red mud arm is located in the red mud dump, is provided with rupture disk in the other end red mud dump of red mud arm.
2. the structure of protection Bayer process red mud according to claim 1 stockyard endless tube is characterized in that described rupture disk Initiation Pressure will be lower than the design pressure of red mud dump endless tube.
3. the structure of protection Bayer process red mud according to claim 1 stockyard endless tube is characterized in that being provided with valve between described red mud dump and the red mud endless tube.
