物脫硫裝置的主要設(shè)備有H2S吸收塔、生物反應(yīng)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(nèi)裝填鮑爾環(huán)和必要的內(nèi)件，以確保吸收液從塔頂部均勻地噴灑到填料塔內(nèi)，氣體在塔內(nèi)與吸收液逆向接觸，使酸性氣中的H2S和部分CO2從氣相轉(zhuǎn)移至液相。為了防止吸收液發(fā)泡，塔頂設(shè)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(yīng)器是脫硫工藝最關(guān)鍵的設(shè)備?？諝鈴牡撞客ㄈ?，使HS-轉(zhuǎn)化為硫。為了提高HS-轉(zhuǎn)化率，在生物反應(yīng)器內(nèi)配置特殊的內(nèi)件，保證了系統(tǒng)的氣液完全混合。同時頂部安裝噴嘴，以防止生物反應(yīng)器內(nèi)的溶液發(fā)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(nèi)部設(shè)有溢流堰，塔頂設(shè)有噴嘴等，使貧液與硫黃顆粒通過靜態(tài)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(nèi)溫度按上低下高的梯度分布，硫漿進入釜內(nèi)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(qū)熔融，硫水分離后的清液上浮從熔硫釜上端旁側(cè)連續(xù)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.
