Problems solved by technology

[0003] In the existing vegetable oil desulfurization equipment, after long-term use, liquid sulfide will inevitably adhere to the inner wall of the desulfurization equipment. If it is not removed from the inner wall of the desulfurization equipment, it will not only affect the subsequent use of the desulfurization equipment
Moreover, the attached liquid sulfide will cause corrosion to a certain extent on the inner wall of the desulfurization equipment, thereby shortening its service life

Abstract

The invention relates to the technical field of desulfurization agent preparation, and concretely relates to a desulfurization agent for an vegetable oil desulfurization device, and a preparation method thereof. The desulfurization agent is prepared from a sodium hydroxide solution, a potassium permanganate solution, diglycolamine, sodium alkyl succinate sulfonate, sodium 1,4-dihydroxy-2-naphthalenesulfonate, aminotrimethylene phosphonic acid, sodium secondary alkyl sulfate, sodium benzotriazole, dodecyldimethylbenzylammonium chloride, isothiazolinone, a surfactant, a defoaming agent and distilled water. The desulfurization agent can remove the stubborn sulfide layer on the inner wall of the desulfurization device; and the aminotrimethylene phosphonic acid and sodium benzotriazole cooperate with each other to effectively reduce the adherence phenomenon of the sulfides, so the cleanliness of the inner wall of the desulfurization device is ensured to a certain extent, and the corrosion rate of the desulfurization device is reduced, thereby the service life of the device is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of desulfurization agent preparation, in particular to a desulfurizer for vegetable oil desulfurization equipment and a preparation method thereof. Background technique [0002] Vegetable oil is a compound composed of unsaturated fatty acid and glycerol. 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. The main components of vegetable oil 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, and ricinoleic acid. [0003] In the existing vegetable oil desulfurization equipment, after long-term use, liquid sulfide will inevitably adhere to the inner wall of the desulfurization equipment. If it is not removed from the inner wall of...
