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和燃煤鍋爐煤中的硫燃燒后主要是以二氧化硫的形態存在，這種呈氣態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助劑來實現脫硫、脫有害氣體的。二氧化硫、及有害氣體和熟石灰在反應助劑的輔助下充分發生化學反應，形成固態硫酸鈣(CaSO₄)和其它附著物，附著在粉塵上或凝聚成細微顆粒，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，根據煙氣中二氧化硫和有害氣體的含量多少而定，過程中設有多組分氣體自動測定裝置，以確保干粉和反應助劑用量的經濟性。熟石灰干粉和反應助劑分別存放在各自的儲罐內，投放量由自動調節裝置控制。

    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.

本產品的特點主要體現在：技術創新、結構創新和工藝創新等。

技術創新：本項目采用干法工藝技術，通過向袋式除塵系統噴射添加特殊助劑活性石灰，除去垃圾焚燒尾氣和燃煤鍋爐尾氣中的二氧化硫(SO₂)及其它有毒、有害成分。該工藝技術實現了袋式除塵器兼固一氣分離和氣一氣分離的功能。為國內處理垃圾焚燒爐尾氣和燃煤鍋爐尾氣提供具有水平的處置設備。

結構創新：設計理念是在不改變袋式除塵器基本原理和除塵效率的前提下，通過結構創新，設計出的袋式除 塵器，將干法脫硫過程融入其中，實現除塵脫硫一體化。

工藝技術創新：本項目為克服目前采用濕法除塵脫硫工藝可能造成水的二次污染和系統結垢堵塞的缺陷，而采用干法除塵脫硫及其它有害氣體的工藝技術。

   Characters of the product are mainly: technical innovation,structural innovation, process innovation and so on.

Technical innovation:This project adopts dry processing technology to eliminate noxious ingredients contained in the tail gas of the incinerator and coal boiler through ejecting active lime into the bag filter.This processing technology realized the function of bag dust remover which consider the needs of both solid-gas and gas-gas separation,meanwhile, it also provides the national tail gas treatment of incinerator and coal boiler with international advanced professional disposal equipment.

Structural innovation: The design concept is to product new type bag filter through structural innovation at the basis of notchanging the filter’s original priniple and dust removal efficiency.

Processing technology innovation:The current semi-drying process could cause secondary water pollution and system scale plugging, while the drying method we are adopting now can overcome such defects.
