Abstract

The invention discloses a method for cracking vegetable oil through an oil-water mixing mode based on a high voltage pulse device. In the traditional method, oil is directly cracked in a pulse electrolysis device, but oil molecules cannot be fully cracked, so that the aim of greatly improving the combustion efficiency of the oil cannot be fulfilled. In the method, oil and water are fully mixed bya mixing agitator, and water molecules and oil molecules are mixed, so that ionization effect areas of the oil molecules are increased, oil chains are easier to break, and the conductivity of the water also can promote the cracking effect of a pulse electric field on carbon chains. The oil chains are continuously cracked, and the small molecular oil with high combustion efficiency obtained by cracking is separated out finally. By adopting the oil-water mixing mode, the cracking degree of the vegetable oil molecules is greatly improved, so that the combustion efficiency of the oil is improved and the oil is more fully combusted.

Description

technical field [0001] The invention belongs to the technical field of cracking oil, and in particular relates to a method for cracking a mixed solution of vegetable oil and water by using a high-voltage pulse electric field device to obtain small molecule oil. Background technique [0002] Vegetable oils (such as rapeseed oil, tung oil, palm oil, linseed oil, etc.) have relatively long carbon chains, large molecules, and low combustion efficiency. The carbon chains can be shortened by cracking, and the oil molecules will become smaller, thereby improving oil quality. combustion efficiency. The current oil cracking method is usually that the oil molecules are ionized and decomposed under the action of a certain frequency of high-voltage pulses, and cracked into many small molecules with short chains. Combined, it improves the combustion efficiency of oil and reduces the emission of harmful gases. However, how to crack the carbon chain of vegetable oil more fully under the ...
