Description
Technical Field
The application relates to the technical field of blast furnace gas desulfurization devices, in particular to a gas fine desulfurization reactant detection experimental device.
Background
Blast furnace gas is a main byproduct generated in the iron-making process flow, contains 22% -30% of CO and a small amount of hydrocarbon, and the balance is nonflammable components. At present, the blast furnace gas of the steel mill is mainly used for hot blast stoves, sintering, pellets, heating furnaces and subsequent boiler power generation after dust removal and purification. However, sulfur compounds in blast furnace gas can generate a large amount of sulfur dioxide during combustion power generation and heating, and the environmental protection requirement is against the stricter and stricter day by day. The related detection result shows that the concentration of the total sulfide in the blast furnace gas is generally 50-300 mg/m 3 . The types of sulfides can be divided into two main types, namely inorganic sulfur including sulfur dioxide and hydrogen sulfide, and organic sulfur including carbonyl sulfide, carbon disulfide, methyl mercaptan, methyl sulfide and the like, and the sulfides in blast furnace gas mainly include hydrogen sulfide and carbonyl sulfide. The prior hydrogen sulfide removal technology is very mature, and the difficulty of the desulfurization technology mainly lies in removal of carbonyl sulfide.
The current methods for removing organic sulfur can be divided into wet method and dry method. The wet method mainly comprises an organic amine solvent absorption method and a liquid catalytic hydrolysis conversion method. The wet method is suitable for removing organic sulfur with high inlet concentration and/or occasions with high gas quantity, has high investment and operation cost, large power consumption and complex operation, is mainly used for removing the organic sulfur in chemical raw material gases such as natural gas, liquefied petroleum gas industry, hydrocarbon and the like, and can not meet the requirement of fine desulfurization due to poor activity of the organic sulfur. The dry method mainly comprises a hydroconversion method, an oxidation method, an adsorption method, a hydrolysis method and the like. Hydroconversion processes, because of their need to convert organic sulfur to H at higher operating temperatures 2 S, the ZnO is removed at high temperature, so that cold and hot diseases in the process are easily caused, and certain side reactions exist. The oxidation process requires operation at high temperatures, and although desulfurization efficiency is high, the oxidant price is high,the investment cost is increased, and the oxidation method can oxidize CO in yellow phosphorus tail gas. The adsorption method is mainly used for high-precision H 2 S is removed, when organic sulfur is removed, the contradiction between the precision and the sulfur capacity exists, the use temperature is higher, generally 300-400 ℃, and when the raw material gas contains CO and CO 2 And hydrocarbon components, methanation side reactions often occur. The hydrolysis method is a main method for removing organic sulfur at present, and the reactant of the hydrolysis method at present has no suitable experimental device, so that the conversion efficiency of the refined desulfurization reactant under the working condition can not be detected.
