物脫硫裝置的主要設備有H2S吸收塔、生物反應器、硫黃沉降槽、熔硫釜等。
The main equipment of the desulfurization device includes H2S absorption tower, bioreactor, sulfur settling tank, sulfur melting kettle, etc.
H2S吸收塔內裝填鮑爾環和必要的內件，以確保吸收液從塔頂部均勻地噴灑到填料塔內，氣體在塔內與吸收液逆向接觸，使酸性氣中的H2S和部分CO2從氣相轉移至液相。為了防止吸收液發泡，塔頂設有噴淋裝置。
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.
生物反應器是脫硫工藝最關鍵的設備。空氣從底部通入，使HS-轉化為硫。為了提高HS-轉化率，在生物反應器內配置特殊的內件，保證了系統的氣液完全混合。同時頂部安裝噴嘴，以防止生物反應器內的溶液發泡。
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.
硫黃沉降槽是底部為錐形的容器，內部設有溢流堰，塔頂設有噴嘴等，使貧液與硫黃顆粒通過靜態沉降的方式予以分離。
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.
熔硫釜內溫度按上低下高的梯度分布，硫漿進入釜內后被逐漸加熱，硫泡沫破裂，細小的硫顆粒聚集變大沉降至釜底高溫區熔融，硫水分離后的清液上浮從熔硫釜上端旁側連續排出。
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.
