Problems solved by technology

[0009] Although the above methods increase the particle size of sulfur particles, the particle size of sulfur particles is small, the suspension rate of sulfur is high, and the settling time is long. A large number of suspended sulfur particles seriously affect the filterability of sulfur when absorbing hydrogen sulfide, and the absorption process in situ The formed sulfur blocks the absorber, and is not conducive to the gas-liquid mass transfer in the absorption process, resulting in a decrease in the desulfurization rate and prone to tower blockage

Abstract

The invention discloses a sulfur particle flocculating agent applicable to iron-based desulfurizing solution. The sulfur particle flocculating agent is composed of a flocculation initiating agent, a flocculation coagulating agent and a flocculation settling agent. By addition of the sulfur particle flocculating agent into complex iron desulfurizing solution, sulfur particles generated in a desulfurizing process can be flocculated and settled in a settling tank spontaneously, and consequently the sulfur particles can be separated out to prevent tower blockage and realize reclaiming of by-product sulfur.

Description

technical field [0001] The invention belongs to the technical field of gas purification, and in particular relates to a sulfur particle flocculant suitable for iron-based desulfurization liquid and a use method thereof. Background technique [0002] In the traditional wet oxidation desulfurization process, due to the rapid mixing of a large amount of gas in the solution and the reaction solution, a gas-liquid-solid suspension is formed, resulting in extremely fine sulfur particles, which are attached to the small bubbles in the solution and float to the surface. The liquid surface forms a sulfur foam layer, which hinders the complete settlement and recovery of sulfur, making filtration difficult; at the same time, the equipment is prone to tower blockage. [0003] The prior art relevant to the present invention is as follows: [0004] 1) US3622273 and US3676356 describe adding alkenol, fatty alcohol, thiosulfate, phosphate and their derivatives to the desulfurization liquid...
