Problems solved by technology

The evaporating device mostly uses a single evaporating retort, so that the material can only be distilled once, resulting in too low concentration of the distilled product, which is not suitable for industrial production; at the same time, water vapor is generally used as the heat transfer medium, which makes the energy loss in the whole process of distillation relatively small. Large, high cost, and the safety factor of the heating device is low, the service life is short, and the depreciation rate of the equipment is high; in addition, the steam generated in the distillation process is not used and discharged, resulting in waste of resources

Embodiment 1

[0009] 1. Evaporation device for making sugarcane juice into syrup.

[0010] Working process: The material liquid enters the bottom of the evaporating retort through the material input pipe under the action of the high-pressure pump, and passes through the through pipe of the heating chamber in the evaporating retort body from bottom to top, and heat is generated between the through pipe and the heat transfer medium in the heating chamber outside the pipe. Exchange, the generated steam moves upward together with the material, and then the material enters the next evaporating retort through the material output pipe, and at the same time, the steam enters the next evaporating retort through the steam output pipe.

[0011] The thermal conductivity of the evaporating retort is preferably a liquid with a high boiling point, low volatility, and not easy to dissipate heat, especially waste lubricating oil; the heat transfer medium of all subsequent evaporating retorts is the steam gen...

Abstract

An evaporating system with multiple distillations is composed of an evaporator, a heater for said evaporator, more than 4 additional evaporators connected sequentially, and a condenser connected to the outlet of heat transfer medium for said additional evaporators. It has high heat utilization rate and uses lubricating oil as heat transfer medium.

Description

[technical field] [0001] The invention relates to a distillation device, in particular to an evaporation device for multiple distillations. [Background technique] [0002] The distillation device is widely used in the purification process after the extraction of liquid substances. The traditional distillation device includes an evaporating retort. The evaporating retort has a closed heating chamber in the retort. The tube and the heating device form a loop connection. There are multiple through pipes sealed with the inside of the heating chamber between the upper and lower sides of the heating chamber. The evaporating retort is respectively provided with a material inlet and a material outlet below and above the heating chamber, and high-temperature steam is injected into the heating chamber. , to heat the through-pipe, thereby heating the material flowing through the through-pipe. The evaporating device mostly uses a single evaporating retort, so that the material can only...
