Description
Technical Field
The invention 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 an iron-making process flow, contains 22-30% of CO and a small amount of hydrocarbon, and the balance is non-combustible components. At present, blast furnace gas of a steel mill is mainly used for hot blast furnaces, sintering, pelletizing, heating furnaces and subsequent boiler power generation after being subjected to dust removal and purification. However, sulfur compounds in blast furnace gas can generate a large amount of sulfur dioxide during combustion power generation and heat generation, which violates increasingly stringent environmental protection requirements. The related detection results show that the concentration of total sulfide in the blast furnace gas is generally 50-300 mg/m3. The types of sulfides can be divided into two main types, one is inorganic sulfur comprising sulfur dioxide and hydrogen sulfide, the other is organic sulfur comprising carbonyl sulfide, carbon disulfide, methyl mercaptan, methyl sulfide and the like, and the sulfides in the blast furnace gas mainly comprise the hydrogen sulfide and the carbonyl sulfide. The prior technology for removing hydrogen sulfide is very goodThe difficulty of the mature and desulfurization technology mainly lies in the removal of carbonyl sulfide.
The current methods for removing organic sulfur can be divided into a wet method and a 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 the organic sulfur with high concentration and/or large amount of gas at the inlet, has high investment and operation cost, large power consumption and complex operation, is mainly used for removing the organic sulfur in chemical feed gas of natural gas, liquefied petroleum gas industry, hydrocarbon and the like, and can not meet the fine desulfurization requirement due to poor activity of the organic sulfur. The dry method mainly includes a hydroconversion method, an oxidation method, an adsorption method, a hydrolysis method and the like. Hydroconversion processes require conversion of organic sulfur to H at higher operating temperatures2S is removed by high-temperature ZnO, which is easy to bring cold and heat diseases on the process and has certain side reactions. The oxidation process needs to be operated at high temperature, although the desulfurization efficiency is high, the price of the oxidant is high, the investment cost is increased, and the oxidation process can oxidize CO in the yellow phosphorus tail gas. The adsorption method is mainly used for high-precision H2The removal of S has the contradiction between precision and sulfur capacity when organic sulfur is removed, the use temperature is higher, generally 300-400 ℃, and when CO and CO exist in raw material gas2And hydrocarbon components, a methanation side reaction often occurs. The hydrolysis method is a main method for removing organic sulfur at present, and the reaction agent of the hydrolysis method has no suitable experimental device at present, so that the conversion efficiency of the fine desulfurization reaction agent under the working condition cannot be detected.
