Embodiment 1

[0036] Such as figure 1As shown, a multi-frequency ultrasonic radiation overflow tank continuous biodiesel production device includes a raw material oil tank 1, a methanol-catalyst storage tank 3, a pre-esterification reactor 5, a step-by-step overflow multi-frequency ultrasonic reactor 8, Glycerin separation tank 11, glycerin tank 12, product washing tank 13, waste water tank 14, crude methyl ester storage tank 15, hot water tank 16, fractionation device 17.

[0037] The raw material oil tank 1 and the methanol-catalyst storage tank 3 are respectively connected to the inlet of the pre-esterification reactor 5 through pipelines. The outlet of the pre-esterification reactor 5 is connected to the first stage of the step-by-step overflow multi-frequency ultrasonic reactor 8 through pipelines. Inlet connection for ultrasonic reaction tank. The outlet of the fourth-stage ultrasonic reaction tank of the stepwise overflow multi-frequency ultrasonic reactor 8 is connected to one end ...

Embodiment 2

[0048] This embodiment is the same as Embodiment 1 except for the subordinate features: this embodiment is mainly aimed at the production process of biodiesel from feedstock oil with moderate acid value.

[0049] For raw material oil with moderate acid value, it can be mixed with concentrated H 2 SO 4 The catalyst is used to catalyze the raw oil to carry out the pre-esterification reaction, and then the potassium hydroxide is used as the catalyst to catalyze the raw oil to carry out the transesterification reaction to prepare biodiesel.

[0050] Raw oil and methanol-concentrated H in raw oil tank 1 and methanol-catalyst tank 3 2 SO 4 The flow of the solution is controlled by the first rotor flow meter 2 and the second rotor flow rate 4 respectively, and flows into the pre-esterification reaction kettle according to a certain alcohol-oil ratio to carry out the pre-esterification reaction; after the acid value drops below 2mgKOH / g, add an appropriate amount of alkali Neutr...

Abstract

The invention discloses a multi-frequency ultrasonic overflow groove continuous biodiesel production device which is low in energy consumption and cost. Biodiesel can be produced by the device with the advantages of high efficiency, energy saving and low consumption. According to the invention, a multi-frequency reverberant ultrasonic field is additionally arranged based on a continuous biodiesel production device, thereby better strengthening mass transfer and heat transfer during ester exchange reaction. Thus, the device disclosed by the invention is a quick and efficient continuous biodiesel production device.

Description

technical field [0001] The invention relates to the technical field of biodiesel production devices, in particular to a multi-frequency ultrasonic overflow tank continuous biodiesel production device. Background technique [0002] Biodiesel is a new type of clean energy that can replace petrochemical diesel through the conversion of various natural animal and vegetable oils through various physical and chemical methods. Its main component is fatty acid methyl ester. Compared with traditional fuel oil, biodiesel has broad application prospects due to its low sulfur content, low cold filter point, good lubricity, high flash point, high cetane number, environmental friendliness and renewable properties. [0003] At present, the methods for preparing biodiesel are mainly divided into physical methods and chemical methods. Among them, the transesterification method in the chemical method is the most widely used because of its simple operation, mature process, excellent product p...
