Description

Technical Field

[0002] With the continuous growth of global energy demand and the increasing awareness of environmental protection, biodiesel, as a renewable and clean alternative energy source, has received widespread attention and research. Biodiesel is usually produced through the transesterification reaction of animal and vegetable oils with alcohols. However, in the process of preparing biodiesel, some substances with odor and harmful components are often produced, such as thiols, carboxylic acids, aldehydes, etc. These substances not only affect the quality and performance of biodiesel, but may also cause pollution to the environment. Therefore, it is necessary to carry out deodorization and purification treatment during the production of biodiesel. The common method is to introduce hot steam into the heated oil. The water vapor passes through the oil containing the odorous components, and the gas-liquid surface contacts. The water vapor is saturated with the volatilized odorous components and escapes according to the ratio of their partial pressures, thereby achieving the purpose of deodorization and purification.

[0049] Working principle: The prepared biodiesel is connected to the upper end of the top solenoid valve 120 through a pipeline, and the high-temperature and high-pressure steam is assembled with the inlet ends of the check valve 1 210 and the check valve 2 310 through a pipeline, and the steam outlet valve 160 is connected to the pipeline of the corresponding exhaust gas treatment and emission equipment; the top solenoid valve 120 is opened and the oil enters the first-stage bin 200 with the cooperation of the top oil inlet pipe 121, and is mixed and reacted with the steam entering through the check valve 1 210. After a period of mixing reaction, the exhaust gas is discharged through the steam outlet valve 160, and the solenoid valve 130 is opened to allow the preliminarily treated biodiesel to enter the second-stage bin 300 and to be mixed and reacted with the steam entering through the check valve 2 310 again, so as to remove the odor components again, and then the solenoid valve 2 140 is opened to enter the third-stage bin 400, and the steam is stirred to exhaust the water content of the steam through the residual heat. After cooling, the treated diesel is discharged by opening the lower solenoid valve 150;

[0050] During operation, the servo motor 510 is controlled to rotate by the distribution box 512 and the switch box 513, thereby driving the lower rotating shaft 420, the middle transfer rod 340 and the upper rotating rod 240 to rotate, thereby driving the scraping frame 410, the middle scraping frame 330 and the upper stirring frame 220 to rotate internally for stirring and scraping.
