生物脱硫处理工程
Biological desulfurization treatment project
沼气生物脱硫
Biogas desulfurization
1、.工程简介
I. Introduction of works
安全:安全将体现在咱们具体规划与施工中的每一个细微的环节。
Safety: safety will be reflected in every detail of our specific planning and construction.
环保:依据江苏三蝶化工有限公司,每天有近21600kgCOD转化为混合沼气,每天的混合沼气产量应为9750m?,经咱们规划的生物脱硫工序后,咱们主张用于沼气发电,是出资小,经济效益最高的挑选。清洁的沼气用一台小型的发电机每天能够发电16500kwh。也能够用以锅炉燃烧等等,主旨是将转化有机污染物成为动力为企业所用。咱们规划的生物脱硫是彻底没有二次污染,将污染的硫化合物转化为单质硫,重新进入自然界的硫循环。
Environmental Protection: According to Jiangsu Santiandi Chemical Co., Ltd., nearly 21600 kg COD is converted into mixed methane every day, and the daily output of mixed methane should be 9750m?. After the bio-desulfurization process we have planned, we advocate that it should be used for biogas power generation, which is the choice with small investment and the highest economic benefit. Clean biogas can be generated by 16500kwh with a small generator every day. It can also be used for boiler combustion and so on. The purpose is to transform organic pollutants into power for enterprises. Our planned biological desulfurization is completely free of secondary pollution, converting the polluted sulfur compounds into elemental sulfur and re-entering the natural sulfur cycle.
人文关心:咱们的规划牢靠.自动化程度高,减低劳动强度,做关闭与无异臭的规划,有利职工的健康。
Humanistic concern: our planning is reliable, highly automated, reduce labor intensity, do the closure and odor-free planning, is conducive to the health of workers.

3、沼气生物脱硫工艺简介
Three. Brief introduction of biogas desulfurization process
本规划按废水处理才能规划;每天去除COD总量21600kg,为每天处理9750m?沼气。处理前沼气的含硫化氢浓度(理论估计值)15000ppm;处理后的沼气含硫化氢浓度不大于100ppm。
This plan can be planned according to the waste water treatment. The total amount of COD removed every day is 21600kg, which is to treat 9750m biogas every day. The concentration of hydrogen sulfide in biogas before treatment (theoretical estimate) was 15 000 ppm, and the concentration of hydrogen sulfide in biogas after treatment was not more than 100 ppm.
本沼气生物脱硫工艺分三个单元:脱硫洗刷 -- 洗刷液生物再生(循环运用) -- 单质硫别离。如下图示:
The biogas desulfurization process is divided into three units: desulfurization scrubbing - biological regeneration of scrubbing solution (recycling) - elemental sulfur separation. The following illustration shows:
碱性的生物H2S吸收液在完结吸收使命后搜集与洗刷塔塔底,进入洗刷液生物净化反应器,反应器中的微生物将液体中吸收的硫化物转化成单质硫,一起使洗刷液再生并坚持碱度。单质硫在硫别离器中别离出体系,单质硫脱水后能够进一步利用,或可直接作为化肥出售,再生的上清液循环回洗刷塔,去脱除气体中的硫化氢。
After completing the absorption mission, the alkaline biological H2S absorbent was collected and scrubbed at the bottom of the scrubbing tower, and then entered the scrubbing liquid bio-purification reactor. The microorganisms in the reactor converted the sulfide absorbed in the liquid into elemental sulfur, which together regenerated the scrubbing liquid and maintained its basicity. The elemental sulfur is separated from the system in the sulfur separator, which can be further utilized after dehydration or sold as fertilizer. The regenerated supernatant can be recycled to the scrubber to remove hydrogen sulfide from the gas.
4、工艺特色:
Four. Process features:
1.脱除效率高;
1. high removal efficiency.
2.收回碱.运转本钱低—与传统的碱洗刷法.化学氧化法(干法)脱硫节约运转本钱几倍乃至几十倍;
2. Recovery of alkali. Low operating cost - and traditional alkali washing method. Chemical oxidation (dry) desulfurization saves operating cost several times or even dozens of times;
3.抗负荷冲击强
3. strong resistance to load.
4.发动很容易
4., it's easy to start.
5.体系的自动化程度能够做得非常好。
5. the automation level of the system can be very good.
