Description

technical field [0001] The invention relates to the technical field of biodiesel production equipment, in particular to a tower-type ultrafine contact reaction device for biodiesel. Background technique [0002] At present, domestic biodiesel production mostly uses waste oil as raw material. The reaction principle is that the free fatty acids and glycerides contained in the hydrophobic phase raw materials contained in the waste oil and the hydrophilic phase alcohols are carried out under the action of catalysts such as acid and alkali. Heterogeneous esterification, transesterification, and finally generate fatty acid methyl ester (commonly known as biodiesel). Most of the production process uses a conventional stirring reaction device. This type of device has high cost, high energy consumption, and low efficiency. During the reaction process of materials, the contact area between molecules of heterogeneous substances is small, the time is short, and the reaction speed is slo...
