Fatty acid and steam separation and recovery device for grease production

Abstract

The invention discloses a fatty acid and steam separation and recovery device for grease production. The device comprises: a condensation tank, wherein a thermal insulation layer is arranged at the inner side of the condensation tank, the upper part of the condensation tank is provided with a condensate water input port, and the lower part of the condensation tank is provided with a condensate water output port; a condensation bin arranged at the inner side of the thermal insulation layer, a partition plate is arranged in the middle of the condensation bin, and a circulation opening is formedin one side of the partition plate; a condensation parallel pipeline arranged in the middle of the partition plate; a temporary storage tank arranged below the condensation tank; a separation tank arranged at one side of the condensation tank; and a separation bin. Fatty acid and steam mixed gas separated from grease is discharged into the condensation tank, and are liquefied through the condensation parallel pipeline to form a mixed liquid, then the mixed liquid is discharged into the separation bin of the separation tank, and standing separation is conducted through using a density difference and a multistage separation structure to make fatty acid and water separated and collected, so the fatty acid and water are not directly discharged into the atmosphere, environmental friendliness isachieved, fatty acid byproducts can be obtained, and production economic benefits are increased.

Description

technical field [0001] The invention relates to oil production equipment, in particular to a fatty acid steam separation and recovery device for oil production. Background technique [0002] Oil production is generally divided into vegetable oil production and animal oil production. For animal oil, it is first necessary to heat the raw fat to separate the oil. This process is generally heated by steam, and then the separated The oil is subjected to impurity removal and dehydration treatment, which will produce more waste water, and then the fatty acid in the oil is removed and the oil is decolorized, and the production is basically completed. The applicant found that when producing oil, it is necessary to separate the fatty acid in the oil. After the oil is heated, because the boiling point of the fatty acid is low, it will first turn into a gas and then be separated by vacuum pumping. After separation, the fatty acid gas is generally mixed with steam Together, and then dir...

Problems solved by technology

The applicant found that when producing oil, it is necessary to separate the fatty acid in the oil. After the oil is heated, because the boiling point of the fatty acid is low, it will first turn into a gas and then be separated by vacuum pumping. After separation, the fatty acid gas is generally mixed with steam Together, and then directly discharged into the atmosphere together, the air pollution is more serious, and the separated fatty acids are also wasted
