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 by a 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 pyrolysis oil, and specifically relates to a method for pyrolyzing a mixture of vegetable oil and water using a high-voltage pulse electric field device to obtain small molecular 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 chain can be shortened by cracking, and the oil molecules can be reduced to improve the oil’s Combustion efficiency. The current method of oil cracking is usually that the oil molecules undergo ionization and decomposition under the action of a certain frequency of high-pressure pulses, and they are cracked into many short-chain small molecules. The molecular weight becomes smaller and ionized, and they are rearranged and combined to increase the fuel molecules and oxygen. Combine it to improve oil combustion efficiency and reduce...
