Microalgae biodiesel production device

Abstract

The invention discloses a microalgae biodiesel production device. The device comprises an oil extraction tank (1), a rectification tank A (2), an esterification tank (5) and a separator (6), wherein an ultrasonic generator (13) is arranged above the oil extraction tank (1), the lower side of the ultrasonic generator (13) is connected with an ultrasonic oscillation rod (14), the bottom end of the oil extraction tank (1) is connected with the middle-lower section of the rectification tank A (2), the top of the rectification tank A (2) is connected with a condenser A (3), the lower end of the condenser A (3) is connected with a solvent recovery tank (4), the bottom of the rectification tank A (2) is connected with the esterification tank (5) through a liquid pump B (16), the bottom of the esterification tank (5) is connected with the separator (6), the bottom end of the separator (6) is connected with a glycerin collector (10) and a feeding port of a rectification tank B (8), and the bottom end of the rectification tank B (8) is connected with a biodiesel collection tank (11). The device has the advantages that energy consumption is low, the structure is simple, reaction time is short, the microalgae oil extraction rate is high, the biodiesel yield is high, the purity is high, and the like.

Description

technical field [0001] The invention relates to the technical field of biodiesel, in particular to a microalgae biodiesel production device. Background technique [0002] Biodiesel refers to oil crops such as soybeans, rapeseed, cotton, palm and other wild oil plants and aquatic vegetable oils such as microalgae, as well as animal oils and catering waste oils, etc., which are made by transesterification or thermochemical processes. Regenerative diesel fuel from petrodiesel. With the increasing depletion of fossil fuels and the sharp rise in oil prices, the search for renewable energy has become a solution to human survival and to maintain the sustainable development of the world economy. As a new alternative energy, biodiesel is developing rapidly in countries all over the world. However, the existing biodiesel production process generally has the following problems: long reaction time, high energy consumption, corrosion of equipment, complex process, high cost, low yield o...
