Technical Field
[0001] The utility model belongs to the technical field of monosaccharide production, and in particular relates to a waste heat utilization device for monosaccharide production. Background Art
[0002] Sugar is a food source for human survival, a structural material for plants, and a major component of the shells of many animals. Sugar is divided into monosaccharides and polysaccharides. Monosaccharides are sugars that can no longer be hydrolyzed and are the basic units of molecules that make up various polysaccharides. Glucose, which everyone is familiar with, is a monosaccharide. Other common monosaccharides include fructose, galactose, ribose, deoxyribose, arabinose, and mannose. In the industrial production of monosaccharides, it is usually necessary to subject the material to a high-temperature and high-pressure reaction. After the reaction is completed, the material needs to be cooled, which consumes electricity. At the same time, during the dissolution of the material, the material needs to be heated, which consumes electricity or steam. In traditional monosaccharide production, each process is independent in heating and cooling, and there is no device for energy exchange between each process. Therefore, the utility model proposes a waste heat utilization device for monosaccharide production to solve the problems existing in the prior art. Utility Model Content

[0015] according to Figure 1As shown, this embodiment provides a waste heat utilization device for monosaccharide production, including a reactor 1, a plate heat exchanger 17, a production water storage tank 25 and a dissolving tank 33.

[0016] The jacket water inlet 7 is connected to the jacket water inlet pipeline 11 and the third valve 27, and is in communication with the circulating water outlet 20 of the plate heat exchanger 17. The pressure relief port 8 is connected to the pressure relief pipeline 12 and the first valve 13, and is in communication with the circulating water inlet 19 of the plate heat exchanger 17.

The pressure of the reactor 1 is discharged, and the fourth valve 29, the first valve 13, the second water pump 24, the fifth valve 30 and the second motor 35 are opened. At this time, the steam in the reactor 1 enters the plate heat exchanger 17 through the pressure discharge pipe 12, is cooled in the plate heat exchanger 17, forms condensed water, and is discharged through the pipe. At the same time, the production water enters the plate heat exchanger 17 from the production water storage tank 25, is heated in the plate heat exchanger 17, and then enters the dissolution tank 33.

At the same time, the production water enters the plate heat exchanger 17 from the production water storage tank 25, is heated in the plate heat exchanger 17, and then enters the dissolution tank 33. Observe and record the values displayed by the first pressure gauge 3, the second thermometer 5, the third thermometer 32, and the fourth thermometer 36. When the value displayed by the second thermometer 5 meets the process parameter requirements, close the valve, water pump and motor, and the cooling of the circulating water is completed.
