Problems solved by technology

[0002] Usually, in the refining process of biodiesel, the raw oil is transported to the preheater by the material pump for preheating, and the raw oil is preheated to 120°C in the preheater, and then enters the refining tower for refining. This process requires a lot of In the refining process, there is a large amount of residual heat in the gas phase that has not been utilized in the refining tower; at the same time, the refined biodiesel needs a large-area cooler on the upper part of the discharge tray to cool the vaporized biodiesel into The liquid phase is discharged to the discharge tray, which results in a lot of waste of heat energy and cooling water

Embodiment Construction

[0011] Below by example the present invention is further described:

[0012] The gist of the present invention is that it relates to a new rectification and energy-saving process in the biodiesel production process. This process contains at least one energy-saving refining device. The structure of the refining device is: a cooler (1), a discharge tray (2), a replacement Heater (3), asphalt storage (4), preheater (5), reboiler (6), raw oil pump (7), refining tower (8), buffer tank (9); it is characterized in that the first During pot refining, the raw oil enters the preheater (9) through the raw oil pump (7), preheats the raw oil to 120°C, enters the reboiler (6) for vaporization, and then connects to the refining tower for vaporization and refining; from the second At the beginning of the pot, the raw material oil can be directly transported to the heat exchanger (3) in the refining tower through the feed pump (7), and the raw material oil is preheated to 120°C by using the va...

Abstract

The invention discloses a rectification energy-saving new process in the biodiesel production process, and in particular relates to a rectification energy-saving new process which takes vegetable oil as raw material to produce the biodiesel; the rectification energy-saving new process is characterized in that: a heat exchanger is additionally arranged below a discharging plate of a refining tower, the raw material oil is directly conveyed to the heat exchanger in the refining tower by a material pump from a second pot, the raw material oil is pre-heated to 120 DEG C by utilizing the vapor phase waste heat, and then the oil is refined at the lower part of the refining tower, so as to save a great amount of heat energy; in addition, the raw material oil can be used for cooling the vapor-phase refined oil, and a great amount of cooling water can be saved; according to actual measurement in the production, the energy can be saved by 2 percent and water can be saved by 10 percent.

Description

Technical field [0001] The invention relates to a new technology of rectification and energy saving in the production process of biodiesel, in particular to a new technology of rectification and energy saving in the process of producing biodiesel with waste animal and vegetable oil as raw materials. Background technique [0002] Usually, in the refining process of biodiesel, the raw oil is transported to the preheater by the material pump for preheating, and the raw oil is preheated to 120°C in the preheater, and then enters the refining tower for refining. This process requires a lot of In the refining process, there is a large amount of residual heat in the gas phase that has not been utilized in the refining tower; at the same time, the refined biodiesel needs a large-area cooler on the upper part of the discharge tray to cool the vaporized biodiesel into The liquid phase is discharged to the discharge tray, which results in a lot of waste of heat energy and cooling water...
