Problems solved by technology

[0003] The main step in the production process of biodiesel is to carry out the esterification reaction and complete the transesterification. At present, acid and alkali two-step esterification or glycerol esterification are mostly used at home and abroad, and the acid-base two-step process will cause serious environmental problems. , while the yield of glycerol esterification method is low and can only reach 60%

Abstract

The invention discloses a technological method for producing biological diesel oil by utilizing an ultrasonic technology. The technological method comprises the following steps: collecting waste hogwash oil; carrying out dehydration, deodorization and impurity removal treatment on the waste hogwash oil to obtain raw oil; enabling the raw oil to pass through a flashing tower, introducing the raw oil into a synthetic tank filled with methanol; after finishing synthesis of the raw oil and the methanol, adding glycerol and mixing; after uniformly mixing, carrying out ester exchange reaction by utilizing an ultrasonic reaction kettle; after reacting, recycling the methanol; separating the raw oil, which is subjected to esterification reaction, by utilizing a rectifying tower so as to obtain light-component oil, middle-component oil and heavy-component oil respectively; introducing the light-component oil, the middle-component oil and the heavy-component oil into a finished-product synthetic tank, and synthesizing finished-product biological diesel oil according to national standards (GB / 100). Compared with a traditional technology, the technological method has the advantages of simplicity in operation, low cost, environment friendliness, high yield and the like; the yield can be improved to 90 percent and the production cost per ton is reduced by 10 percent to 20 percent; the technological method is suitable for industrial production and has wide application prospect.

Description

technical field [0001] The invention relates to the technical field of renewable energy, in particular to a process method for producing biodiesel by using ultrasonic technology. Background technique [0002] With the sounding of the energy crisis alarm bell, it has become a consensus of mankind to develop and utilize biomass energy to produce clean energy projects on the premise of intensive energy utilization. The development and utilization of new energy and renewable energy will become a new area of ​​concern for various companies around the world. Diesel is an important strategic material of the country and is widely used as diesel engine fuel for vehicles, ships, national defense, agricultural machinery, mechanical power and other equipment. At present, the annual domestic demand for diesel oil exceeds 200 million tons, and is increasing at an annual rate of 8%. For this reason, the country has to spend a large amount of foreign exchange to import diesel oil and crud...
