Problems solved by technology

[0002] Biodiesel is a kind of green energy with low sulfur content. The product obtained by conventional production process can reach the National IV standard. In recent years, with the increase of diesel consumption and the upgrading of vehicle diesel, the production of high-quality and high-brand biodiesel Diesel has become inevitable, and most petrochemical diesel manufacturers have upgraded their standards to National V, while the existing biodiesel production process can no longer meet the requirements of National V standards, and the existing desulfurization technologies are all developed for petrochemical diesel, which cannot be used for biodiesel. Diesel desulfurization

Embodiment 1

[0050] Waste oil (sulfur content is 350mg / Kg) 10 tons, pumped into the aeration reaction tank 3, the oil-water ratio is 1:1, the concentration of salt water is 0.5%, the aeration plate 4 is opened, the air-water ratio is 5:1, the waste oil Stay in the aeration reaction tank 3 for 20 minutes, centrifuge after the aeration reaction, remove a large amount of sulfur-containing impurities, proteins, colloids, etc. in the waste oil, the centrifuge discharge directly enters the ultrasonic tank 9, and open the clear water feed pump 8 at the same time, The oil-water ratio is 1:1, and the ultrasonic frequency is turned on to 10MHz. The oil-water mixture generates free radicals and annihilates bubbles under the action of ultrasonic cavitation. Remove it into the waste water, stand still and separate the water to obtain the secondary desulfurization raw material oil, the raw material oil pump 12 continuously pumps the secondary desulfurization raw material oil into the atmospheric distilla...

Embodiment 2

[0052] 10 tons of swill oil (sulfur content is 300mg / Kg), pumped into the aeration reaction tank 3, the oil-water ratio is 1:2, the concentration of salt water is 0.3%, the aeration plate 4 is opened, the air-water ratio is 3:1, and the swill oil Stay in the aeration reaction tank 3 for 40 minutes, centrifuge after the aeration reaction, remove a large amount of sulfur-containing impurities, proteins, colloids, etc. in the waste oil, and the centrifuge discharge directly enters the ultrasonic tank 9, and simultaneously turns on the clear water feed pump 8, The oil-water ratio is 2:1, and the ultrasonic frequency is turned on to 6MHz. Under the action of ultrasonic cavitation, the oil-water mixture generates free radicals and annihilates bubbles. Remove it into the waste water, stand still and separate the water to obtain the secondary desulfurization raw material oil, the raw material oil pump 12 continuously pumps the secondary desulfurization raw material oil into the atmosph...
