Description

Technical Field

[0001] The utility model relates to the technical field of alumina production, and particularly relates to an energy-saving device for a water supply pump of a decomposition cooling plate heat exchanger. Background Technique

[0002] The decomposition cooling plate is a special heat treatment tool, which has a wide range of applications in industrial production, especially in the fields of steel heat treatment and alumina production. This plate is usually made of high-temperature resistant materials, and its design allows the cooling medium to flow through it, thereby effectively reducing the temperature of the material.

[0003] In the prior art, the task of the decomposition workshop in the alumina production industry is to add seeds to the refined sodium aluminate solution after cooling it through a plate heat exchanger and then enter the first decomposition tank. Under the induction of the seeds, AL(OH)3 begins to precipitate. Since the temperature further decreases during the decomposition process, and the solution can only maintain a certain degree of supersaturation, AL(OH)3 continuously precipitates, new crystal nuclei are continuously generated, and the crystal nuclei grow and agglomerate. After a cycle, the product AL(OH)3 is obtained at the end tank discharge. This process requires strict control of the decomposition temperature. If the appropriate initial temperature cannot be obtained after heat exchange with the mother liquor, the previous regulation method is to turn on the water supply pump of the plate heat exchanger and the fan of the plate heat exchanger cooling tower to cool down with water. A large amount of electric energy is consumed during the operation of the water supply pump of the plate heat exchanger and the fan of the plate heat exchanger cooling tower. Therefore, the utility model proposes an energy-saving device for a water supply pump of a decomposition cooling plate heat exchanger to solve the above problems. Content of the Utility Model

[0024] The coolant in the coolant tank 2 is pumped into the suction pipe 9 by starting the plate heat exchanger water supply pump 3 in advance, and then enters the inside of the liquid storage connecting pipe 4 through the connection of the connecting pipe 10, so that the coolant is first stored in the inside of the liquid storage connecting pipe 4, which is convenient for subsequent supply of cooling water by the intermediate water supply pump 5.

[0025] One end of the liquid storage connecting pipe 4 is provided with an intermediate water supply pump 5. One side of the intermediate water supply pump 5 is equipped with an output pipe 6.
