Problems solved by technology

[0005] The present invention aims at the problems existing in the above-mentioned prior art. After many years of practice, it has been continuously improved. Based on the theory of reaction kinetics and chemical equilibrium, it follows the principle that the smaller the particle size of the desulfurizer is, the more uniform the distribution is and the higher the reaction conversion rate is. Provides an industrial heavy fuel emulsification combustion desulfurization process, which solves the problems of large desulfurization investment and high operating costs in the prior art

Abstract

The invention relates to an emulsification, combustion and desulphurization process of an industrial heavy fuel, comprising the following steps of: preparing a sulfur-removing assistant, preparing emulsified oil, and removing sulfur. The invention has the advantages of low equipment investment, high sulfur-removing efficiency, low running cost, rapid and thorough reactive transformation and high utilization rate of a desulfurizing agent; the addition amount of the desulfurizing agent can be adjusted along the sulfur content of the fuel so that the invention achieves balanced energy efficiency; reactive products are beneficial and innocuous for the qualities of sintering and fusing products, in particular for molten glass, and the dosages of a fusing assistant and a clarifying agent can be reduced.

Description

technical field [0001] The invention relates to a heavy fuel desulfurization process, in particular to an industrial heavy fuel emulsification combustion desulfurization process. Background technique [0002] At present, most of the desulfurization technologies used in my country's industrial production are limited to flue gas desulfurization. Flue gas desulfurization is to install a desulfurization device in the smoke exhaust part of the combustion equipment. It adopts desulfurization processes such as swirl plate, bubble atomization, packed tower, electrostatic and electron beam, and absorbs, absorbs, oxidizes, neutralizes and other physical and chemical The process achieves the removal of SO 2 The purpose of acidic substances (HF, HCl). The treatment process is divided into dry method, wet method and semi-dry method in the industry. Each has its own strengths, and the effect is still good. [0003] However, no matter which method, there is a large investment, and the ...
