Abstract

The invention provides a biodiesel continuous esterification reaction tower. A methyl alcohol outflow tube, a top pressure meter and a demister are arranged on the top of a reaction tower shell, a feed tube and 8-15 tower sections communicated with the feed tube are arranged in the middle of the reaction tower shell, temperature monitors are arranged on the outer walls of the tower sections, and a liquid baffle, tower bottom heaters, a liquid level and a diesel outflow tube are arranged at the bottom of the reaction tower shell. The biodiesel continuous esterification reaction tower has the advantages of being reasonable in design, continuous in esterification reaction, high in esterification reaction efficiency and raw material utilization rate and the like, and can be used for preparing biodiesel.

Description

technical field [0001] The invention belongs to the technical field of gas-liquid reaction chemical equipment, and in particular relates to a biodiesel continuous esterification reaction tower. Background technique [0002] The Outline of the "Twelfth Five-Year Plan" pointed out that the dual control of energy consumption intensity and total amount should be implemented, and the cultivation and development of new energy sources should be accelerated. Actively carry out the development and utilization of non-fossil energy such as water energy, nuclear energy, wind energy, solar energy, and biomass energy. With the worldwide energy shortage and people's increasing emphasis on environmental protection, the task of developing and researching biodiesel, a green and environmentally friendly fuel, to replace the depleted petroleum has become an urgent technical problem to be solved. [0003] Most of the raw materials for domestic biodiesel production are waste oils (gutter oil, ho...
