生物脱硫工艺的装置作用介绍

物脱硫装置的主要设备有H2S吸收塔、生物反应器、硫黄沉降槽、熔硫釜等。

The main equipment of the desulfurization device includes H2S absorption tower, bioreactor, sulfur settling tank, sulfur melting kettle, etc.

H2S吸收塔内装填鲍尔环和必要的内件,以确保吸收液从塔顶部均匀地喷洒到填料塔内,气体在塔内与吸收液逆向接触,使酸性气中的H2S和部分CO2从气相转移液相。为了防止吸收液发泡,塔顶设有喷淋装置。

The H2S absorption tower is filled with a Bauer ring and necessary internal components to ensure that the absorption liquid is evenly sprayed into the packing tower from the top of the tower. The gas in the tower contacts the absorption liquid in reverse, causing H2S and some CO2 in the acidic gas to transfer from the gas phase to the liquid phase. In order to prevent the absorption liquid from foaming, a spray device is installed at the top of the tower.

生物反应器是脱硫工艺关键的设备。空气从底部通入,使HS-转化为硫。为了提高HS-转化率,在生物反应器内配置特殊的内件,保证了系统的气液完全混合。同时顶部安装喷嘴,以防止生物反应器内的溶液发泡。

Bioreactors are the most critical equipment in desulfurization processes. Air enters from the bottom, converting HS - into sulfur. In order to improve the HS conversion rate, special internal components are installed in the bioreactor to ensure complete gas-liquid mixing in the system. Install a nozzle at the top to prevent foaming of the solution inside the bioreactor.

硫黄沉降槽是底部为锥形的容器,内部设有溢流堰,塔顶设有喷嘴等,使贫液与硫黄颗粒通过静态沉降的方式予以分离。

The sulfur settling tank is a container with a conical bottom, an overflow weir inside, and a nozzle at the top of the tower to separate the lean liquid and sulfur particles through static settling.

熔硫釜内温度按上低下高的梯度分布,硫浆进入釜内后被逐渐加热,硫泡沫破裂,细小的硫颗粒聚集变大沉降釜底高温区熔融,硫水分离后的清液上浮从熔硫釜上端旁侧连续排出。

The temperature in the sulfur melting kettle is distributed according to the gradient of upper, lower and higher. The sulfur slurry is gradually heated after entering the kettle. The sulfur foam breaks, and the small sulfur particles gather and settle to the high temperature area at the bottom of the kettle for melting. The clear liquid after sulfur water separation floats up and is discharged continuously from the side of the upper end of the sulfur melting kettle.
