Problems solved by technology

[0002] Ethanol is an important chemical raw material. In the process of industrial production of ethanol, it is necessary to distill the ethanol mixed solution, so as to realize the separation by using the different boiling points of the components in the mixed solution. However, the existing distillation tower device for ethanol extraction mainly uses a single control The internal temperature and pressure of the distillation tower can be regul

Abstract

The invention relates to the technical field of chemical equipment, in particular to a safe distillation tower device for ethanol extraction. The device comprises a first supporting seat, wherein a distillation still is fixedly arranged above the first supporting seat through bolts, a butt joint seat is integrally formed above the distillation still, and a distillation tower main shell is fixedlyarranged above the butt joint seat through bolts. The safe distillation tower device of the invention has the beneficial effects that a designed safe distillation tower structure can be controlled bya first controller and a second controller together to respond to faults in time, so when the pressure in the distillation tower main shell is increased violently, the power supply of a heater can becut off in time, and ethanol steam in the distillation tower main shell and the distillation still can be cooled in time to realize rapid pressure reduction, the phenomenon that the distillation towermain shell is broken and serious chemical accidents are incurred due to sudden pressure change caused by out-of-control temperature adjustment of the heater under various reasons can be effectively avoided, and the property safety of a factory and the personal safety of workers are effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a safe distillation tower device for ethanol extraction. Background technique [0002] Ethanol is an important chemical raw material. In the process of industrial production of ethanol, it is necessary to distill the ethanol mixed solution, so as to realize the separation by using the different boiling points of the components in the mixed solution. However, the existing distillation tower device for ethanol extraction mainly uses a single control The internal temperature and pressure of the distillation tower can be adjusted by using a controller and a thermostat. When the control system fails, the internal pressure of the distillation tower can easily rise and cause the distillation tower to rupture. The existing treatment methods mainly use manual periodic inspection and monitoring to avoid further expansion of the danger, but the reliability of manual inspection an...
