沼气生物脱硫技术分为哪几个重要阶段?

含硫废气脱硫是从产生硫元素的气体中去除硫化氢的生物工艺。吸收硫元素的生物溶液是一种碳酸氢盐水溶液,系统中加入氢氧化钠以维持碱度和PH值,同时在系统中添加营养物质并补充水分。这种生物溶液中含有处理含硫的细菌,在初始启动的时候只需要加一次就可以了。

Sulfur containing waste gas desulfurization is a biological process that removes hydrogen sulfide from the gas that produces sulfur elements. The biological solution that absorbs sulfur elements is a bicarbonate saline solution. Sodium hydroxide is added to the system to maintain alkalinity and pH value, while nutrients are added to the system and water is replenished. This biological solution contains bacteria that can handle sulfur, and only needs to be added once during the initial start-up.

生物溶液从生物反应器中泵送到洗涤塔顶部,在接触器中它被均匀的喷洒在洗涤塔的填料填充床上,确保生物溶液与含硫气体之间适当的接触。通过洗涤塔内发生的物理化学反应,硫化氢以硫化物的形式溶解在生物溶液里,处理后的气体向动到洗涤塔顶部的出口。

The biological solution is pumped from the bioreactor to the top of the washing tower, and it is evenly sprayed on the packing bed of the washing tower in the contactor, ensuring appropriate contact between the biological solution and sulfur-containing gas. Through the physical and chemical reactions occurring inside the washing tower, hydrogen sulfide dissolves in the form of sulfides in the biological solution, and the treated gas flows upwards to the outlet at the top of the washing tower.

在洗涤塔阶段生物溶液中存在的硫细菌不参与反应,仅仅是将气体中的硫元素分离出来并聚集在洗涤塔的底部,然后再采用泵将底部富集硫化氢的液体输送到生物反应器里。红外侦探仪会探测生物反应器中硫化物的浓度,通过变频的方式驱动控制一台鼓风机为细菌输送合理的空气量。

The sulfur bacteria present in the biological solution during the washing tower stage do not participate in the reaction. They simply separate the sulfur elements from the gas and aggregate them at the bottom of the washing tower. Then, a pump is used to transport the liquid enriched with hydrogen sulfide at the bottom to the bioreactor. The infrared detector will detect the concentration of sulfides in the bioreactor and drive a blower to deliver a reasonable amount of air to the bacteria through frequency conversion.

所产生的单质硫是亲水性的不会引起系统堵塞。通过硫的释放洗涤液已经被再生,将再次被泵送到洗涤塔的顶部进行新的处理循环。

The generated elemental sulfur is hydrophilic and will not cause system blockage. The washing solution has been regenerated through the release of sulfur and will be pumped back to the top of the washing tower for a new treatment cycle.

第三个阶段也就是一个阶段,部分洗涤液被分离出来并泵送到重力沉降器中,生物硫被浓缩10%15%的单质硫。"硫淤渣的脱水将采用离心机或压滤机的形式进行渣水分离,沉降器溢流和分离后的滤液被重复使用。

In the third and final stage, a portion of the washing solution is separated and pumped into a gravity settler, where biological sulfur is concentrated at 10% to 15% elemental sulfur. The dehydration of sulfur sludge will be carried out in the form of a centrifuge or filter press for slag water separation, and the overflow of the settler and the separated filtrate will be reused.

生物硫以硫饼的形式产生,按重量计算硫的含量在55%到75%之间,因为有一小部分硫化物会被氧化成硫酸盐,部分溶液需要流出因此需要补充补给水和氢氧化钠,以确保电导率保持在一定范围内。生物过程中产生的生物硫构成了许多非常有效的液体悬浮液浓缩物,它可以作为硫基剂或肥料硫组分。

Biological sulfur is produced in the form of sulfur cakes, with sulfur content ranging from 55% to 75% by weight. This is because a small portion of sulfides are oxidized into sulfates, and some solutions need to flow out. Therefore, supplementary water and sodium hydroxide are needed to ensure that the conductivity remains within a certain range. The biological sulfur generated during biological processes constitutes many highly effective liquid suspension concentrates, which can be used as sulfur based fungicides or fertilizer sulfur components.
