Waste heat recycling system of vegetable oil refining production line

Abstract

The invention discloses a waste heat recycling system of a vegetable oil refining production line, and relates to the field of vegetable oil refining. The waste heat recycling system comprises a wasteheat collecting module used for collecting heat energy generated by a heating module on the vegetable oil refining production line; a vegetable oil refining production line module used for accuratelyanalyzing a specific heat consumption link, a specific heating temperature and a specific medium on the production line; and a waste heat utilization module used for carrying out secondary utilization on collected waste heat. According to the invention, the waste heat collecting module is arranged; heat exchange can be carried out on a heating link on the vegetable oil refining production line module; the system comprises a deacidification module, an alkali refining module, a hydrogenation module, an esterification module and a deodorization module, the temperature of each heating link is accurately analyzed, then a heat exchange module performs heat exchange utilization according to the specific temperature of different heating links, waste heat on the production line is used for production and living, and heat energy waste is avoided.

Description

technical field [0001] The invention relates to the field of vegetable oil refining, in particular to a waste heat recycling system of a vegetable oil refining production line. Background technique [0002] Vegetable oil is a compound composed of unsaturated fatty acid and glycerin. It is widely distributed in nature. It is the oil obtained from the fruit, seed and germ of plants, such as peanut oil, soybean oil, linseed oil, castor oil, rapeseed oil, etc. Vegetable oil The main components of oleic acid are esters of straight-chain higher fatty acids and glycerol. In addition to palmitic acid, stearic acid and oleic acid, fatty acids also contain a variety of unsaturated acids, such as erucic acid, oleic acid, ricinoleic acid, etc. Vegetable oil mainly contains vitamin E, K, calcium, iron, phosphorus, potassium and other minerals, fatty acids, etc. Fatty acids in vegetable oils make the skin moisturized and shiny. [0003] In the existing vegetable oil refining production ...

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the problem that there are many refining links that need to be heated in the existing vegetable oil refining production line, and these heat energies are not collected in the later stage, resulting in waste of heat energy, and the heating links on the refining and chemical production line need to be heated every time. Both need to be reheated, resulting in the waste of electric energy. A waste heat recycling system for vegetable oil refining production lines is provided.
