The scientific name of denitrification is SCR selective catalytic reduction technology.
With high denitration efficiency (70-90%), it is a mature denitration process and the most widely used denitration technology.
It means that nitrogen oxides in flue gas react selectively with reducing agent to generate nitrogen and water, and remove nitrogen oxides (NOx) in flue gas.
在SCR脫硝系統(tǒng)中，各種廢氣中含有的NOx和氨水、尿素或其他含有氨基的物質(zhì)進(jìn)行反應(yīng)，生成氮?dú)夂退?/div>
In SCR denitration system, NOx contained in various waste gases reacts with ammonia water, urea or other substances containing amino groups to generate nitrogen and water.
脫硝路線設(shè)計(jì)的考慮
Consideration of denitration route design
經(jīng)處理排出的NOx必須滿足國家和當(dāng)?shù)卣h(huán)保要求；
The NOx discharged after treatment must meet the national and local environmental protection requirements;
脫硝工藝要做到技術(shù)成熟、設(shè)備運(yùn)行可靠，并有較多成功的運(yùn)行業(yè)績；
The denitration process should be mature in technology, reliable in equipment operation and have more successful operation performance;
根據(jù)工程的具體情況選擇合適的方案，盡量減少成本費(fèi)用；
Select the appropriate scheme according to the specific situation of the project to minimize the cost;
催化劑具有良好的抗高溫老化性能力，良好的抗硫老化和再生性能。
The catalyst has good resistance to high-temperature aging, sulfur aging and regeneration.
脫硝系統(tǒng)管道布置合理，可實(shí)現(xiàn)煙氣脫硝系統(tǒng)和余熱裝置的串聯(lián)。
The pipeline layout of denitration system is reasonable, which can realize the series connection of flue gas denitration system and waste heat device.
脫硝設(shè)計(jì)方案要做到經(jīng)濟(jì)性和實(shí)用性并存，與客戶合作是雙贏的結(jié)果。
The denitration design scheme should be economical and practical, and cooperation with customers is a win-win result.
