摘要/Abstract

摘要：

燃煤电厂脱硫工艺产生的脱硫废水具有高盐分、腐蚀性和结垢性等特点，是电厂废水处理中最难的一个环节。基于H型电解池对脱硫废水及其辅助煤电解的特性进行了研究，在脱硫废水资源化利用的同时吸纳燃煤电厂的过余电力。结果表明：脱硫废水经过酸化后电解性能明显高于水，可以降低电解制氢的电耗；仅脱硫废水不能促进煤的电氧化，仍需要添加部分铁离子作为催化剂，但未经酸化的脱硫废水可以促进铁离子的催化作用，从而进一步降低电解制氢的电耗。基于此，提出了酸化处理、直接利用和添加煤粉3种可能的电解脱硫废水制氢的工艺手段。

Abstract:

The desulfurization wastewater produced by the desulfurization process of coal-fired power plants has the characteristics of high salinity, corrosiveness and scaling, which is the most difficult part in the treatment of wastewater. The characteristics of desulfurization wastewater-assisted coal electrolysis were studied based on H-type electrolytic cell, so as to realize the simultaneous utilization of desulfurization wastewater and excess power from coal-fired power plants. The results show that the electrolytic performance of desulfurization wastewater after acidification is significantly higher than that of water, which can reduce the power consumption of hydrogen production by electrolysis. Desulfurization wastewater alone cannot promote the electrical oxidation of coal, so iron ions are still needed to be added as catalyst. Unacidified desulfurization wastewater can promote the catalytic effect of iron ions, thereby further reducing the power consumption of hydrogen production. Based on this, three possible processes of desulfurization wastewater electrolysis for hydrogen production, including acidification treatment, direct utilization and pulverized coal addition, were proposed.

Key words: coal-fired power plants, hydrogen production, desulfurization wastewater, coal electrolysis, energy storage, coal water slurry
