一、絡(luò)合鐵濕法脫硫工藝的基本原理。
1、 The basic principle of complex iron wet desulfurization process.
采用螯合鐵離子作為催化劑，堿性溶液作為吸收劑，達(dá)到脫硫化氫的目的。化學(xué)反應(yīng)原理分為兩個(gè)部分：脫硫吸收過(guò)程和再生過(guò)程。
Using chelated iron ions as catalysts and alkaline solutions as absorbers, the goal of hydrogen sulfide removal is achieved. The principle of chemical reaction is divided into two parts: desulfurization absorption process and regeneration process.
1、吸收氧化總反應(yīng)方程式：
1. The total reaction equation for absorption oxidation:
H2S(g)+2Fe3+(L)→2H+(L)+S↓+2Fe2+(L)
H2S(g)+2Fe3+(L)→2H+(L)+S↓+2Fe2+(L)
2、再生過(guò)程：為恢復(fù)溶液吸收硫化氫的能力，就必須對(duì)溶液進(jìn)行再生，再生過(guò)程主要發(fā)生氧化析硫反應(yīng)：
2. Regeneration process: In order to restore the solution's ability to absorb hydrogen sulfide, it is necessary to regenerate the solution. The regeneration process mainly involves oxidation and sulfur evolution reaction:
1/2O2(g)+H2O(L)+2Fe2+(L)→2OH-(L)+2Fe3+(L)
1/2O2(g)+H2O(L)+2Fe2+(L)→2OH-(L)+2Fe3+(L)
