沼氣發(fā)電機(jī)組煙氣脫硝系統(tǒng)主要包括SCR反應(yīng)器系統(tǒng)、控制系統(tǒng)、尿素溶液計量噴射系統(tǒng)、傳感器和壓縮空氣輔助系統(tǒng)等。脫硝系統(tǒng)具有凈化效率高、可靠、背壓小（極大程度上減少了脫硝對內(nèi)燃發(fā)電機(jī)組的影響）、安裝位置合理，占地面積小且保養(yǎng)、維修方便等特點；同時對排煙管道和反應(yīng)器均進(jìn)行了合理布置和優(yōu)化設(shè)計，既能滿足使用要求，又可增加系統(tǒng)的脫硝效率和使用壽命，可謂一舉兩得。

The flue gas denitrification system of biogas generator unit mainly includes SCR reactor system, control system, urea solution metering and injection system, sensors, and compressed air auxiliary system. The denitrification system has the characteristics of high purification efficiency, safety and reliability, low back pressure (greatly reducing the impact of denitrification on internal combustion generator sets), reasonable installation position, small footprint, and convenient maintenance and repair; At the same time, reasonable arrangement and optimized design were carried out on the smoke exhaust pipes and reactors, which can not only meet the usage requirements but also increase the denitrification efficiency and service life of the system, which can be said to kill two birds with one stone.

此外，在催化劑、噴槍、泵閥以及自動控制系統(tǒng)的選用和設(shè)計上河北漢藍(lán)技術(shù)人員同樣進(jìn)行了充分的考慮，將的技術(shù)與項目本土化特點相結(jié)合研發(fā)出的自動控制系統(tǒng)具有體積小、組裝維護(hù)方便、可靠性高且抗干擾能力強(qiáng)等特點，同時大大減少了操作人員數(shù)量。

In addition, the technical personnel of Hebei Hanlan have also fully considered the selection and design of catalysts, spray guns, pump valves, and automatic control systems. The automatic control system developed by combining advanced technology with local characteristics of the project has the characteristics of small size, easy assembly and maintenance, high reliability, and strong anti-interference ability, while greatly reducing the number of operators.

在該項目中，漢藍(lán)嚴(yán)格按照項目要求在設(shè)備及配件的材質(zhì)、脫硝催化劑的選用、尿素溶液的計量、噴射與防堵，設(shè)備滿足不同溫度使用環(huán)境且延長使用壽命等經(jīng)濟(jì)和適用性方面均進(jìn)行了針對性設(shè)計，在滿足當(dāng)?shù)嘏欧旁诰€監(jiān)測標(biāo)準(zhǔn)的基礎(chǔ)上，盡可能降低運(yùn)行成本，通過多項低度電成本的優(yōu)化設(shè)計來大大降低業(yè)主經(jīng)濟(jì)負(fù)擔(dān)。

In this project, Hanlan strictly followed the project requirements and carried out targeted design in terms of equipment and accessory materials, selection of denitrification catalysts, metering of urea solution, injection and anti blocking, equipment meeting different temperature usage environments and extending service life. On the basis of meeting local emission online monitoring standards, Hanlan tried to reduce operating costs as much as possible and greatly reduced the economic burden of the owner through multiple low electricity cost optimization designs.
