Abstract

The invention discloses a method for cracking vegetable oil in an oil-gas mixing way based on a high-pressure pulse device. In the traditional way, oil is directly cracked in a pulse electrolysis unit, but oil molecules can not be completely cracked, thus the purpose of great improvement on the combustion efficiency of the oil can not be achieved. The method of the invention makes oil and gas completely mix by a mixing device, gas molecules and the oil molecules are mixed to increase the ionization area of the oil molecules, the chains of oil are easier to break, the electrical conductivity of the gas also facilitates the crack capability of a pulse electric field on the chains of carbon, and the chains of oil are continuously cracked, and finally the cracked micro-molecular oil with highcombustion efficiency is separated. The invention greatly improves the cracking degree of vegetable oil molecules in the oil-gas mixing way so as to improve the combustion efficiency of the oil and make the oil combust more completely.

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 liquid of vegetable oil and gas 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 acti...
