The invention provides a novel blast furnace gas desulfurization purification system and a purification process. The novel blast furnace gas desulfurization purification system comprises a primary organic sulfur conversion reactor, a secondary organic sulfur conversion reactor, a TRT / BPRT device, a desulfurization tower, a regeneration tank, a sulfur foam tank and a filter press, wherein the first-stage organic sulfur conversion reactor, the second-stage organic sulfur conversion reactor and the TRT / BPRT device are sequentially communicated through pipelines; the TRT / BPRT device is connected with the desulfurization tower through a pipeline; a rich liquid pump is used for feeding liquid at the bottom of the desulfurization tower into the regeneration tank, the middle of the regeneration tank is communicated with the sulfur foam tank through a pipeline after treatment of the regeneration tank, and the filter press is arranged below an elevated tank and fed into a sulfur melting kettle after treatment of the filter press to complete the blast furnace gas desulfurization and purification process. According to the organic sulfur conversion process, organic sulfur components in the blast furnace gas can be efficiently converted, most organic sulfur components in the blast furnace gas are converted into inorganic sulfur, the requirement for environment-friendly ultra-low emission ofcombustion flue gas SO2 of follow-up users of the blast furnace gas is met, and the process is economical and practical.
Description
technical field [0001] The invention belongs to the technical field of blast furnace gas purification technology, and in particular relates to a purification technology of a novel blast furnace gas desulfurization purification system. Background technique [0002] Most of the existing blast furnace gas desulfurization and purification technologies are simple purification processes such as adsorption and washing, and most of them are simple and intermittent experimental devices, and there is no relatively complete desulfurization and purification industrial device that has been successfully operated so far. The disadvantages of the adsorption and washing process are low desulfurization purification rate, unsatisfactory desulfurization effect, high operating costs, continuous, stable and efficient operation, and large-scale application to the blast furnace ironmaking desulfurization process with large-scale continuous operation.
