Description
Technical Field
The utility model relates to a heating device, in particular to a settling tank circulating heating device for producing energy-saving aluminum oxide.
Background
The existing aluminum oxide production settling tank for industrial production is fed from the top of the settling tank, and dissolved slurry has heat loss in the conveying process through a feeding pipeline, so that the dissolved slurry needs to be heated when entering the settling tank, the hydrolysis loss of the slurry is reduced, and the yield of aluminum oxide is increased. In the production operation process, steam is conveyed from the upper part of the precipitation tank, the slurry in the settling tank for producing the aluminum oxide is heated at a low speed, the waste of steam energy is caused, a large amount of steam is discharged to the atmosphere through the exhaust funnel, and when the slurry in the settling tank is heated, the upper part is at a high temperature, the lower part is low, the hydrolysis loss of the slurry is large, the yield of the aluminum oxide is reduced, the normal operation of production is influenced, and the production is greatly influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide an energy-saving sedimentation tank circulation heating device for aluminum oxide production, which has simple structure, convenient operation and energy saving.
In order to achieve the above purpose, the utility model adopts the technical scheme that: the utility model discloses an energy-saving subsider circulation heating device for alumina production, including the cell body, be provided with inlet pipe, discharging pipe, admission line and the pipeline of giving vent to anger on the cell body, the discharging pipe sets up in the cell body bottom, still includes heater and steam coil, and steam coil sets up and is close to the bottom in the cell body, evenly is provided with the venthole on the steam coil, the air inlet of heater is connected with the intake pipe, intake pipe one end and cell body upper portion intercommunication, and the gas outlet of heater is connected with the circulating line, circulating line and steam coil intercommunication, be provided with separator and fluid-discharge tube on the discharging pipe, the feed inlet and the terminal intercommunication of discharging.
Preferably, the discharge port of the separator is provided with a valve.
Preferably, the liquid discharge pipe is arranged perpendicular to the discharge pipe.
Compared with the prior art, the utility model has the advantages of: the utility model has simple structure and convenient operation, and is provided with the heater which can circularly heat the gas in the settling tank, thereby saving energy; set up the steam coil who evenly takes out the gas pocket in the lower part of subsider for the thick liquids heating is abundant in the subsider, and it is fast to heat up, reduces steam and arranges to atmospheric loss, practices thrift the steam quantity, practices thrift heat energy, reduces the alumina hydrolysis loss, increases alumina output, sets up separator and fluid-discharge tube on the discharging pipe, is convenient for separate alumina, does benefit to the implementation.
