法脱硫技能流程是什么样的?

湿法脱硫技能简介

Introduction to wet desulfurization skills
湿法脱硫技能是使气体中的硫化氢在富含催化剂的液相中氧化成单质硫的一种脱硫技能。该技能的流程比照简略,能够直接得到元素硫。首要用于处理二氧化碳浓度高的气体进行脱硫,比方沼气。该技能的关键在于设备某些参数挑选是不是契合实际需要。
Wet desulfurization technology is a desulfurization technology to oxidize hydrogen sulfide in gas into elemental sulfur in liquid phase rich in catalyst. The process of this skill is relatively simple, and elemental sulfur can be obtained directly. It is mainly used to process gases with high carbon dioxide concentration for desulfurization, such as biogas. The key to this skill lies in whether the selection of some parameters of the equipment meets the actual needs.
2.1脱硫基本原理
2.1 basic principle of desulfurization
在有催化剂参加下的脱硫,可分为两个进程:吸收和再生。吸收进程首要发生在吸收硫化氢的脱硫塔内。首要反响如下
Desulfurization with catalyst can be divided into two processes: absorption and regeneration. The absorption process mainly occurs in the desulfurization tower that absorbs hydrogen sulfide. The primary response is as follows
2.2湿法脱硫技能流程
2.2 wet desulfurization skill process
脱硫液以碳酸钠作为碱源,总碱度为0.3~0.6N,NaHCO3:Na2CO3≥5且pH值为8.2~8.5;催化剂溶解后混入脱硫液。
The desulfurization solution uses sodium carbonate as the alkali source, the total alkalinity is 0.3 ~ 0.6N, nahco3:na2co3 ≥ 5 and the pH value is 8.2 ~ 8.5; The catalyst is dissolved and mixed with desulfurization solution.
工作时,含硫沼气从脱硫塔底部进入,与脱硫液逆向触摸,硫化氢被碱液吸收,净化后的沼气从塔顶排出。吸收硫化氢后的脱硫液成为富液,流经富液槽,再被泵打入再生槽,与空气混合进行再生,其间硫以单质形态浮于槽顶,溢流到硫膏槽。再生后的脱硫液成为贫液,恢复脱硫才能,经贫液槽,再被泵循环进入脱硫塔持续脱硫。
During operation, the sulfur-containing methane enters from the bottom of the desulfurization tower and touches the desulfurization solution in the opposite direction. Hydrogen sulfide is absorbed by the alkali solution, and the purified methane is discharged from the top of the tower. The desulfurized liquid after absorbing hydrogen sulfide becomes rich liquid, flows through the rich liquid tank, is pumped into the regeneration tank, and is mixed with air for regeneration. During this period, sulfur floats on the top of the tank in the form of simple substance and overflows to the sulfur paste tank. After regeneration, the desulfurized liquid becomes lean liquid, and the desulfurized liquid can be recovered. After passing through the lean liquid tank, it is pumped into the desulfurizing tower for continuous desulfurization.
