Abstract
The utility model discloses a dissolving tank is used in aluminium hydroxide preparation belongs to aluminium hydroxide preparation areas of expertise, including cell body and steam coil pipe, its characterized in that: cell body inner wall and outer wall enclose into a cavity, the steam coil pipe in the cavity and encircle on cell body inner wall lateral surface, the steam coil pipe include two coil pipes, have steam inlet and steam outlet on two coil pipes respectively. Compared with the prior art it hangs down, puies forward the fast characteristics of thermal velocity to have the power consumption.
Description
Technical field
The utility model relates to a kind of dissolver, particularly a kind of aluminium hydroxide preparation dissolving tank.
Background technology
Bayer process aluminium hydroxide is through stirring and dissolving after Steam Heating, make the supersaturated sodium aluminate solution that floating material is higher, the supersaturated sodium aluminate solution injection HTHP dissolving tank that the floating material obtained is higher, after airtight, pass into steam, the supersaturated sodium aluminate solution making floating material higher under uniform temperature and pressure condition, heat-insulation pressure keeping certain hour, obtain the sodium aluminate solution that floating material is very low, be thick liquid; The mode heated up to dissolving tank is at present mainly in dissolving tank has Steam Heating layer, has steam pipe coil, by passing into the object that steam reaches intensification in steam pipe coil in Steam Heating layer.
The steam pipe coil generally used at present is integral type, and programming rate is very slow, simultaneously because coil pipe development distance is very large, needs to maintain force value remain on 8kg/cm through measuring and calculating
2could maintain the normal operation of firing equipment, when entering into holding stage, owing to not needing too many heat, need vapour pressure force value to reduce, to save energy resource consumption, but once force value is lower than 8kg/cm
2, firing equipment just can not normal operation, affect the normal progress of work.
Utility model content
Technical assignment of the present utility model is for above the deficiencies in the prior art, provides a kind of aluminium hydroxide preparation dissolving tank.
The technical scheme in the invention for solving the technical problem is: a kind of aluminium hydroxide preparation dissolving tank, comprise cell body and steam pipe coil, it is characterized in that: described cell body inner and outer wall surrounds a cavity, described steam pipe coil is in cavity and be looped around on cell body inner wall outside face, described steam pipe coil comprises two coil pipes, and two coil pipes have steam inlet and steam (vapor) outlet respectively.
Two above-mentioned coil pipes are upper coil pipe and lower coil pipe.
Two above-mentioned coil pipes are the first coil pipe and the second coil pipe, and the first above-mentioned coil pipe and the second coil pipe are spaced, and the first above-mentioned coil pipe or the second coil pipe intert the levels gap at the second coil pipe or the first coil pipe.
Fluted on above-mentioned cell body inner wall outside face, steam pipe coil is in groove.
Compared with prior art, the utility model has following outstanding beneficial effect:
1, original overall steam pipe coil is divided into two, carries out heat supply respectively, reduce heat supply force value, and it is fast to put forward thermal velocity.
2, at holding stage, owing to not needing too many heat, only needing unlatching one road steam to carry out heat supply can satisfy the demand, and namely holding stage maintains force value 4kg/cm
2, reduce energy resource consumption, and ensure that normal heat supply.
3, utilize cyclic steam to provide heat for dissolving tank, original overall steam pipe coil is divided into two, the steam of different amount is provided for different phase, reduces cost, be convenient to promote and use.
Accompanying drawing explanation
Fig. 1 is the utility model cell body and steam pipe coil position relationship structural representation.
Fig. 2 is the structural representation of two coil pipes in the utility model embodiment 1.
Fig. 3 is the structural representation of two coil pipes in the utility model embodiment 2.
Detailed description of the invention
Below in conjunction with specification drawings and specific embodiments, the utility model is further illustrated.
As shown in Figure 1, the utility model comprises cell body and steam pipe coil 3, and described cell body inwall 1 and outer wall 2 surround a cavity.Described steam pipe coil 3 is in cavity and be looped around on cell body inwall 1 lateral surface.In prioritization scheme, fluted on described cell body inwall 1 lateral surface, steam pipe coil 3, in groove, makes most of area of steam pipe coil 3 be close to outside cell body inwall 1, heat conduction distance is reduced, and strengthens heat transfer rate.Described steam pipe coil 3 comprises two coil pipes, and two coil pipes have steam inlet and steam (vapor) outlet respectively, and namely two coil pipes independently.
As shown in Figure 2, in embodiment 1, two described coil pipes are upper coil pipe 4 and lower coil pipe 5.When needs heat, simultaneously up logical steam in coil pipe 4 and lower coil pipe 5, original overall steam pipe coil 3 is divided into two sections, reduce heat supply force value, and it is fast to put forward thermal velocity, at holding stage, owing to not needing too many heat, only need make a logical steam in coil pipe 4 or lower coil pipe 5, namely holding stage maintains force value 4kg/cm
2, reduce energy resource consumption, ensure that normal heat supply.
As shown in Figure 3, in example 2, in order to ensure heat insulation effect, two described coil pipes are the first coil pipe 6 and the second coil pipe 7, the first described coil pipe 6 and the second coil pipe 7 are spaced, the first described coil pipe 6 or the second coil pipe 7 intert the levels gap at the second coil pipe 7 or the first coil pipe 6, and the first coil pipe 6 and the second coil pipe 7 are independently.When original coil pipe length of run is constant, coil pipe is divided into spaced two sections, during heating, simultaneously toward logical steam in the first coil pipe 6 and the second coil pipe 7, put forward thermal velocity fast, because the first coil pipe 6 and the second coil pipe 7 are evenly distributed on dissolving tank, when separately steam being led to the first coil pipe 6 or the second coil pipe 7, heat radiation is even, high insulating effect.
The steam inlet of steam pipe coil 3 is connected steam boiler with steam (vapor) outlet, provides steam by steam boiler.
During concrete use, utilize cyclic steam to provide heat for dissolving tank, original overall steam pipe coil 3 is divided into two, the steam of different amount is provided for different phase, under the prerequisite reducing energy resource consumption, ensure that normal heat supply is incubated, reduce cost, be convenient to promote and use.
It should be noted that; particular of the present utility model has been described in detail the utility model; for a person skilled in the art, the various apparent change carried out it when not deviating from spirit and scope of the present utility model is all within protection domain of the present utility model.
