Problems solved by technology
Among them, the hot water pump 3 is used for drainage, that is, to discharge the hot water in the hot water seal tank 1. When the hot water pump 3 breaks down and needs to be repaired, because the water in the seal tank 1 cannot be discharged, the causticizing process of salt discharge must be forced Parking makes production passive, causing production bottlenecks and economic losses

Embodiment
[0022] see figure 1 and figure 2 . A hot water seal tank of a salt discharge causticization system is characterized in that it includes a ground tank wall 5 of the hot water seal tank and an overall heightened tank wall 6 connected to the ground tank wall. The side wall at the highest water level inside the tank is communicated with a drainpipe 2, and the outlet end of the drainpipe 2 is communicated with the circulating water return well. The highest water level is located at the heightened tank wall 6 or the top of the heightened tank wall 6, and the heightened tank wall may be more than 1 meter, preferably 1.5 meters.
[0023] The nominal diameter of the drain pipe 2 is 200mm-800mm, preferably 500mm. The length of the drainage pipe is 5-15 meters, depending on the distance from the circulating water return well. Drainage pipe 2 can be provided with one, also can be provided with two or more than two as required.
[0024] The preparation method of the above-mentioned h...

Abstract
The invention discloses a hot water sealing tank of a salt elimination causticization system and a preparation method thereof. The hot water sealing tank comprises a ground grooved wall of the hot water sealing tank and an integrally heightened grooved wall connected to the upper part of the ground grooved wall. A side wall at the highest water level position in the hot water sealing tank is communicated with a water drain pipe. An outlet of the water drain pipe is communicated with a circulating water return well. The hot water sealing tank breaks directed thinking of necessary use of a drainage pump in the hot water sealing tank, and thoroughly solves the bottleneck problem that the salt elimination causticization process is influenced by the hot water pump. The hot water pump of the lower water sealing tank can be stopped or has other uses in emergency so that an equipment maintenance cost is reduced, electric energy consumption is effectively reduced and a cost is saved.
Description
technical field [0001] The invention relates to equipment transformation of a salt-expelling causticization system, and belongs to the field of alumina production equipment, in particular to a hot water-sealed tank of a salt-expelling causticization system and a preparation method thereof. Background technique [0002] The main production task of the causticization process of salt discharge is to remove carbonate in the alumina production process, which is an important process of alumina production, and the hot water seal tank is one of the main equipment of the causticization process of salt discharge, which is directly related to the entire Can the causticizing system for salt discharge be in normal production? [0003] In the prior art, the hot water sealing tank of the causticizing system for salt discharge in the evaporation workshop of alumina production is as follows: figure 1 As shown, the heat sealing tank 1 includes an annular tank wall, a tank roof, a circulating...
