| description | The invention provides a method and a device for reducing secondary salt in a coal gas desulfurization liquid, the method for reducing secondary salt in the coal gas desulfurization liquid comprises the following steps: mixing nitrogen and air, and inputting the mixed gas into a regeneration tower to react with the desulfurization liquid, and the volume ratio of the nitrogen to the air is 0.01-0.99. Nitrogen and air are mixed to reduce the amount of oxygen reacting with the desulfurization liquid, and by controlling the proportion of the nitrogen and the air, the regeneration of the desulfurization liquid is met, meanwhile, the generation amount of secondary salt in the desulfurization liquid is effectively controlled, and energy consumption is reduced.
本发明提供了一种降低煤气脱硫液副盐的方法及装置，所述降低煤气脱硫液副盐的方法包括：将氮气和空气混合，将混合气体输入再生塔与脱硫液反应，其中，氮气与空气的体积比为0.01～0.99。本发明通过将氮气与空气混合降低与脱硫液反应的氧气量，并通过控制氮气与空气的比例，满足脱硫液再生的同时，有效控制脱硫液中副盐生成量，减少了能源消耗。 |
