我們通過多年的實踐經(jīng)驗，對噴射再生槽進(jìn)行了改進(jìn)，提高了氧化和再生的效率，使得再生槽內(nèi)浮選出的單質(zhì)硫呈泡沫懸浮于液面上，充分氧化后硫泡沫的濃度會大大提高，硫泡沫量減少，大大降低了熔硫時間和蒸汽耗量，同時也提高了貧液的品質(zhì)，降低了脫硫的運行成本。
Through years of practical experience, we have improved the jet regeneration tank, improved the efficiency of oxidation and regeneration, and made the flotation of the sulfur in the regeneration tank foam on the liquid surface. After the oxidation, the concentration of the sulfur foam will be greatly increased, the amount of sulfur foam will be reduced, the time of melting sulphur and the consumption of steam will be greatly reduced, and the quality of the poor liquid will also be improved. The operation cost of desulfurization is reduced.
采用獨特的雙塔串聯(lián)濕法脫硫工藝，徹 底解決了運行出現(xiàn)硫磺堵塔的難題。
The unique double tower series wet desulfurization process has completely solved the problem of sulfur blocking in operation.
濕法脫硫系統(tǒng)
Wet desulfurization system
1、氣體流程：
1. Gas flow:
自前工段來的煤氣進(jìn)入濕法脫硫塔底部，自下而動，與上部噴淋下的脫硫液逆流接觸，煤氣中的H2S被吸收，塔頂出來的煤氣進(jìn)入捕液裝置，捕除煤氣中的部分水份后凈化氣(H2S≤20mg)后去下工段。
The gas from the front section enters the bottom of the wet desulfurization tower, flows from bottom to top, contacts with the desulfurization liquid under the upper spray counter current, the H2S in the gas is absorbed, and the gas from the top of the tower enters the liquid catching device, after removing part of the water in the gas, the purified gas (H2S ≤ 20mg) goes to the lower section.
2、脫硫液流程：
2. Desulfurization liquid process:
由脫硫底部出來的脫硫液（俗稱富液），經(jīng)過一定的緩充熟化，經(jīng)再生泵加壓到0. 4Mpa送到再生器頂部噴射器，富液高速通過噴射器噴嘴時，噴射器吸氣室形成負(fù)壓自動吸入空氣，富液與空氣兩
The desulfurizing liquid (commonly known as rich liquid) from the bottom of the desulfurizer, after a certain slow charging and ripening, is pressurized to 0.4MPa by the regeneration pump and sent to the ejector at the top of the regenerator. When the rich liquid passes through the ejector nozzle at a high speed, the suction chamber of the ejector forms a negative pressure and automatically sucks in air
相并流經(jīng)噴射器喉管、擴(kuò)散管由尾管排出并由再生槽底部并流向動。此時，富液中的懸浮硫顆粒被空氣浮選形成泡沫漂浮在再生槽上部，溢流至硫泡沫槽內(nèi)。再生合格的脫硫液（俗稱貧液）
The phase parallel flows through the throat pipe of the ejector and the diffusion pipe, which is discharged from the tail pipe and flows upward from the bottom of the regeneration tank. At this time, the suspended sulfur particles in the rich liquid are floated by air to float on the upper part of the regeneration tank and overflow into the sulfur foam tank. Regeneration of qualified desulfurization liquid (commonly known as lean liquid)
經(jīng)液位調(diào)節(jié)閥從再生器中部出來去脫硫塔，貧液經(jīng)脫硫泵加壓后送入脫硫塔頂部循環(huán)使用。
Through the liquid level control valve, it comes out from the middle of regenerator to desulfurization tower, and the lean liquid is pressurized by desulfurization pump and then sent to the top of desulfurization tower for recycling.
硫泡沫經(jīng)泡沫泵加壓后去熔硫系統(tǒng)，經(jīng)蒸汽（蒸汽壓力0.4-0.6MPa）加熱，被加工成硫磺付產(chǎn)物出售，其中產(chǎn)生的清液經(jīng)降溫、活化、沉淀后返回溶液系統(tǒng)。
The sulfur foam is pressurized by foam pump to melt sulphur system, heated by steam (steam pressure 0.4-0.6MPa), and processed into sulfur product. The resulting liquid is returned to the solution system after cooling, activation and precipitation.
原始開車及補充軟水在收集槽中完成。脫硫劑補充由脫硫塔入口貧液管加入。
The original start-up and replenishment of soft water are completed in the collection tank. The desulfurizer supplement is added by the lean liquid pipe at the inlet of the desulfurizer tower.
