A dehydration device before the preparation of biodiesel

Abstract

The invention discloses a dehydration plant before preparation of biomass diesel oil, which comprises a tray, and a preheating tank and a high-temperature dehydrating tank; the preheating tank and the high-temperature dehydrating tank are installed on the top part of the tray; bottom parts of the preheating tank and the high-temperature dehydrating tank are connected through a connecting pipe, and the middle part of the connecting pipe is equipped with an oil pump; a high thermal conductive ceramic layer is arranged at the inner wall of the bottom part of the preheating tank, and the inner part of the high thermal conductive ceramic layer is aligned with first electric heating pipe in a spiral form; the outer part of the left side of the preheating tank is equipped with a first electric heating controller, and an electric output end of the first electric heating controller is connected to an electric connector end of the first heating pipe. Through arranging the preheating tank and the high-temperature dehydrating tank, the dehydration plant integrates the oil grease preheating and grease high-temperature distillation and dehydration, and can effectively shorten the time length for the grease heating, distillation and dehydration, and greatly improve the grease distilling and dehydration efficiency.

Description

technical field [0001] The invention relates to the technical field of biomass diesel production and processing equipment, in particular to a dehydration device before the preparation of biomass diesel. Background technique [0002] At present, in the process of biodiesel production, when the bio-refined oil enters the biomass diesel production system, the oil needs to be dehydrated first. However, at present, most of the equipment used for oil dehydration uses a tank to dehydrate the oil. Distillation dehydration, low working efficiency, and the existing grease dehydration equipment, the tank body heated by the grease is usually heated by the edge of the tank body. After a long time of use, a layer of grease is easily formed on the inner wall of the tank, which affects the inner wall of the tank. The heat conduction effect prolongs the heating time of oil and reduces the efficiency of oil distillation and dehydration processing. Contents of the invention [0003] The pur...
