Device and method for preparing biologic diesel oil by using microalgae to adsorb carbon dioxide

Abstract

The invention discloses a device and method for preparing biologic diesel oil by using microalgae to adsorb carbon dioxide. The device comprises an equipment main body and a light source outer hood, wherein the light source outer hood consists of two semicircle stainless steel hoods; prismatic columns with LED lamp strips are arranged on arc-shaped plates of the stainless steel hoods; the equipment main body comprises a glass housing; the glass housing is provided with a two-layer housing wall; a clamping cavity is formed between two layers of the housing wall; a temperature sensor and electrical heating rods are arranged in the clamping cavity; a stirring mechanism, a gas uniform distributing plate and a PH meter are arranged in the glass housing; and a cooling box and an air transportingpump communicate with the glass housing. The method comprises the following steps of obtaining microalgae spices high in oil content, and performing small-scale culturing; enabling the cultured microalgae spices to massively adsorb the carbon dioxide in the device, and obtaining algae biomasses; performing centrifuging on the obtained algae biomasses, performing cleaning, and performing freeze drying; and performing ultrasonic crushing, and then extracting fat. Through the adoption of the device disclosed by the invention, a stable environment is provided for microalgae to adsorb carbon dioxide, so that the adsorption effect of the microalgae to the carbon dioxide is improved, and the biological fat transformation efficiency is improved.

Description

Technical field [0001] The invention relates to a device and method for preparing biodiesel, in particular to a device and method for preparing biodiesel by microalgae adsorbing carbon dioxide. Background technique [0002] At present, biodiesel is mainly produced with plant and animal fatty acids as raw materials, but biodiesel produced with plant and animal fatty acids such as oil crops as raw materials is far from meeting the vast demand for fuel in today’s society. At the same time, oil crops are used. There are still the following problems when plants such as biodiesel are produced: First, whether plants such as oil crops can stably achieve high yields; second, if large areas of oil crops are planted, it will lead to a shortage of land resources, which will induce crop prices to rise and affect people’s lives. Daily life. [0003] Facing the many problems of using oil crops as raw materials to produce biodiesel, the use of microalgae to produce biodiesel is gradually emerging...

Problems solved by technology

[0002] At present, biodiesel is mainly produced with vegetable and animal fatty acids as raw materials, but biodiesel produced with oil crops and other plant and animal fatty acids as raw materials is far from meeting the vast demand for fuel in today's society. At the same time, the use of oil crops There are still the following problems when plants such as biodiesel are produced: first, whether oil crops and other plants can achieve high yields stably; daily life

Nowadays, most of the devices used for microalgae to absorb carbon dioxide cannot provide a stable environment for the growth of microalgae, thereby affecting the reproduction of microalgae and affecting the bio-oil production of microalgae; moreover, the existing devices for microalgae to absorb carbon dioxide It is difficult to make microalgae fully contact with carbon dioxide, which reduces the effect of microalgae to absorb carbon dioxide to a certain extent, and then affects the effect and efficiency of microalgae to produce biodiesel

In addition, the existing process of producing biodiesel from microalgae still has defects such as low catalytic efficiency and high labor intensity, which greatly increases the production cost.
