除塵脫硫、脫有害氣體一體化是指把煙氣的除塵和脫硫、脫有害氣體在同一工藝過程中完成，本技術(shù)是通過對袋式除塵工藝的改進(jìn)和創(chuàng)新來實(shí)現(xiàn)這一過程的，因此我們稱之為除塵脫硫一體化袋式除塵技術(shù)。以此命名，可以使人們形象地理解為該技術(shù)是在袋式除塵器的基礎(chǔ)上增加了脫硫、脫有害氣體的功能，或理解為采用了具有脫硫、脫有害氣體功能的袋式除塵器。這種一體化袋式除塵技術(shù)在性能上保留了袋式除塵器的全部技術(shù)特征。鑒于袋式除塵器已廣泛地用于建材、化工、冶金、非金屬礦、糧食等行業(yè)；對其收塵方面的技術(shù)原理不再詳細(xì)介紹，只重點(diǎn)介紹相關(guān)的脫硫、脫有害氣體技術(shù)。

  As a high efficient process of removing the noxious gas containted in fume, the dry process system adopts the utilised scheme to simplify the system, cuts cost as well as decreases the error rate. By improving the dedusing technics can we realized the aforementioned process, that’s why we call it dry process system of hazardous gas. Given that the bag filter has been widely used in buliding material, chemical industry, metaluygy,non-metallic mineral and food industry,ect. We will put the emphas is on its noxious gas removal techniques instead of expanding on its technical principles.

 

垃圾焚燒爐尾氣中的有害物質(zhì)和燃煤鍋爐煤中的硫燃燒后主要是以二氧化硫的形態(tài)存在，這種呈氣態(tài)的二氧化硫和有害氣體是無法用任何其它種類除塵器收集和捕捉的。本技術(shù)是通過向含有粉塵、二氧化硫和有害氣體的煙氣中噴射熟石灰干粉和反應(yīng)助劑來實(shí)現(xiàn)脫硫、脫有害氣體的。二氧化硫、及有害氣體和熟石灰在反應(yīng)助劑的輔助下充分發(fā)生化學(xué)反應(yīng)，形成固態(tài)硫酸鈣(CaSO₄)和其它附著物，附著在粉塵上或凝聚成細(xì)微顆粒，隨粉塵一起被袋式除塵器收集下來。

    The noxious gas contained in the tail gas out of garbage incinerator and coal burning boiler is collected by bag filter with japanese techniques, This technology can achieve desulfuration and harmness gas through ejecting slaked lime dry power and reaction auxiliary agent to fult gas, sulfur dioxide and harmful gas.harmful gas and slake lime carry chemical reaction adequay,forming solidastate calcium sulfate and and other attachments, which will either adhere to stive or coacervate into nice granule and finally been absorbed.

 

     熟石灰干粉和助劑的投放量，根據(jù)煙氣中二氧化硫和有害氣體的含量多少而定，過程中設(shè)有多組分氣體自動測定裝置，以確保干粉和反應(yīng)助劑用量的經(jīng)濟(jì)性。熟石灰干粉和反應(yīng)助劑分別存放在各自的儲罐內(nèi)，投放量由自動調(diào)節(jié)裝置控制。

    Dos of slaked lime dry powder and reaction assistant is up to the quantity of noxious gas, there are groups of sub-gas automatic tester which ensures economic usage of dry powder and reaction auxiliary agents. Slaked lime dry powder and reaction auxiliary agents is desposited in stock tank respectively and the input amout is controlled by automatic tester.
