Abstract
The present invention discloses a steam exhausting method and a device for a high-pressure dissolving condenser. The method comprises the steps that when steam exhaust is carried out to the condenser, steam in the condenser is firstly exhausted to an expansion groove for pressure reduction, and then the steam which is depressurized is exhausted through the expansion groove. The device comprises the condenser, wherein an exhaust pipe is arranged on the condenser and is communicated with the expansion groove; the top of the expansion groove is provided with a gas outlet and a gas inlet, a gas outlet pipe for air exhaust is connected to the gas outlet, and the bottom of the expansion groove is provided with a liquid discharge hole; a liquid trap used for carrying out steam-liquid separation is arranged in the expansion groove. Compared with the prior art, the present invention has the advantage that liquid drops with alkali in the gas exhausted by the condenser is greatly reduced, and the present invention also has the advantage that environmental pollution is reduced.
Description
Technical field:
The present invention relates to a kind of exhausting method and device that is used for alumina producing mesohigh stripping condenser, belong to high-pressure dissolving condenser steam discharge technical field.
Technical background:
In alumina producing, the stripping of aluminum ore high temperature to be become ore pulp, in this process, can produce a large amount of steam, in the end the ore pulp of one-level ore pulp flash-pot enters the exhaust steam temperature of discharging behind the dilution trap about 100 ℃, in order to make full use of the heat of steam, usually steam is delivered to heating new water (or recirculated water) in the high-pressure dissolving condenser, then the water of heating is delivered to the hot water station, be used for other production processes.In the prior art, the direct emptying of gas that the steam in the condenser uses the back to produce.But also have small amount of drop in this gas, wherein contain alkali,, environment is polluted if directly the discharging meeting damages human body.
Summary of the invention:
The objective of the invention is to: provide a kind of condenser that can reduce to discharge high-pressure dissolving condenser exhausting method and the device that the band alkali lye in the gas drips,, thereby reach the purpose of protecting environment with of the pollution of minimizing drop to environment.
The present invention is achieved in that high-pressure dissolving condenser exhausting method of the present invention is: when carrying out the condenser steam discharge, the vapour in the condenser is discharged in the dilatation groove carries out step-down earlier, and then the vapour after this step-down is discharged by the dilatation groove.
High-pressure dissolving condenser steam exhaust device of the present invention is: it comprises condenser (1) and be provided with blast pipe (2) on condenser (1), on the blast pipe (2) of condenser (1), be connected with a dilatation groove (3), be provided with gas outlet (4) and air inlet (8) at the top of dilatation groove (3), on gas outlet (4), be connected with emptying escape pipe (5), be provided with outage (6) in the bottom of dilatation groove (3); The liquid trap (7) that is used to carry out vapor-liquid separation is housed in dilatation groove (3); Liquid trap (7) is by center drum (9), vortex chamber (11), the last vertex of a cone (14) and the following vertex of a cone (15) are formed, the centre of liquid trap (7) is center drum (9), center drum (9) top seal, be provided with 1～4 air admission hole (10) at its sidepiece, the outer correspondence of each air admission hole (10) is provided with a vortex chamber (11), each vortex chamber (11) is made up of two arc plates (12) and the cover plate in top (13) of both sides, be provided with the last vertex of a cone (14) of annular in the upper end of center drum (9), be fixed with the following vertex of a cone (15) of annular in the lower end of center drum (9), bottom at the following vertex of a cone (15) is provided with discharging tube (17), in the center of the last vertex of a cone (14) blast pipe (16) is installed.
Owing to adopted technique scheme, the present invention presses hot vapour to be discharged into earlier in the dilatation groove on the band in the high-pressure dissolving condenser to carry out step-down, and then the vapour after this step-down discharged by the dilatation groove, this can not only reduce effectively to discharge to be with in the vapour and contains alkali lye and drip, and can also reduce the temperature and pressure of discharging vapour, discharge the pollution of vapour thereby reduce greatly to environment.Therefore, the present invention compared with prior art, the present invention not only has and can significantly reduce condenser and discharge the advantage that the band alkali lye in the gas drips, but also has the advantage that can reduce environmental pollution.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present invention;
Accompanying drawing 2 is the structural representation of liquid trap of the present invention;
Accompanying drawing 3 is the A-A cutaway view in the accompanying drawing 2.
The specific embodiment:
Embodiments of the invention: make dilatation groove (3) with a cylindrical container, open a gas outlet (4) at the crown center of dilatation groove (3), open an air inlet (8) in the position of top-side, the blast pipe (2) of condenser (1) is connected with air inlet (8), (4) are gone up and are connected an emptying escape pipe (5) in the gas outlet, make an outage (6) in the bottom of dilatation groove (3), and the outlet of outage (6) is connected to recovery system with pipeline.
In order to make the better effects if of vapor-liquid separation, a liquid trap (7) can be installed in dilatation groove (3), liquid trap (7) can directly adopt the finished product in the existing market to install, but, because structure more complicated, the cost of the liquid trap of being sold in the market are also higher, so its liquid trap preferably adopts the structure of the liquid trap described in the present invention (7).The separating effect of vapour-liquid can be better like this.
Liquid trap of the present invention (7) is by center drum (9), vortex chamber (11), the last vertex of a cone (14) and the following vertex of a cone (15) are formed, in dilatation groove (3), weld the following vertex of a cone (15) that the center is with holes with steel plate and shaped steel during making, welding the center drum (9) that a side has the air admission hole (10) of 3 rectangles on the vertex of a cone (15) centre bore down then, then according to the position of air admission hole (10), reaching installation three vortex chamber (11) between center drum (9) on the vertex of a cone (15) face down: the two blocks of side plates (12) with vortex chamber (11) are welded on the center drum (9) earlier, again a vortex chamber are finished in cover plate (13) and biside plate (12) and center drum (9) welding.Finish all the other two vortex chamber according to said method, on the outer wall of the following vertex of a cone (15) and container inner wall, the discharging tube (17) that the drop after 6 confessions separate refluxes is installed then; The weldering of finishing the vertex of a cone (14) with steel plate and shaped steel is at last pressed, and in the last vertex of a cone (14) center a blast pipe (16) is installed.
