在工業(yè)生產(chǎn)過程中產(chǎn)生的大量電石氣等工業(yè)尾氣比較穩(wěn)定，如果能將這些尾氣進(jìn)行有效利用，就能減少生產(chǎn)企業(yè)能源消耗或者高昂的工業(yè)用電成本，在當(dāng)前的環(huán)保大趨勢(shì)下也是個(gè)非常不錯(cuò)的選擇，其電能可以被用作本廠區(qū)的設(shè)備用電，也可以作為備用電能儲(chǔ)存起來或者辦公區(qū)域用電。目前在發(fā)電方面以小電量發(fā)電為主，但隨著企業(yè)規(guī)模的不斷發(fā)展，產(chǎn)生的馳放氣的量增加，同時(shí)在燃燒方面的改進(jìn)以及燃?xì)廨啓C(jī)發(fā)電效率的提高，將會(huì)使馳放氣在發(fā)電方面也會(huì)有著更廣泛的應(yīng)用。
The large amount of industrial exhaust gas, such as calcium carbide gas, generated in the industrial production process is relatively stable. If these exhaust gases can be effectively utilized, it can reduce energy consumption or high industrial electricity costs for production enterprises. In the current trend of environmental protection, it is also a very good choice. Its electricity can be used for equipment in the factory area, as well as for backup energy storage or office area electricity. At present, small electricity generation is the main focus in power generation. However, with the continuous development of enterprise scale, the amount of exhaust gas generated increases. At the same time, improvements in combustion and the improvement of gas turbine power generation efficiency will make exhaust gas more widely used in power generation.
由此可見，電石氣作為一種清潔能源用來發(fā)電，既能夠節(jié)省成本，又可以減少污染，對(duì)企業(yè)來說無疑是一大利好。但對(duì)于馳放氣發(fā)電后排放的尾氣還需要做進(jìn)一步的處理，才能達(dá)到環(huán)保標(biāo)準(zhǔn)。為此，陜西一家利用馳放氣發(fā)電的公司從我公司訂制了一套馳放氣發(fā)電機(jī)組煙氣脫硝系統(tǒng)來對(duì)機(jī)組尾氣中的NOX進(jìn)行處理，并實(shí)現(xiàn)了達(dá)標(biāo)排放。下面我們就來看下這套系統(tǒng)的基本原理和特點(diǎn)。
From this, it can be seen that calcium carbide gas, as a clean energy source used for power generation, can save costs and reduce pollution, which is undoubtedly a great benefit for enterprises. However, further treatment is needed to meet environmental standards for the exhaust emissions from the power generation of the exhaust gas. Therefore, a company in Shaanxi that utilizes exhaust gas to generate electricity has customized a set of exhaust gas denitrification system for exhaust gas generation units from our company to treat NOX in the unit's exhaust gas and achieve standard emissions. Let's take a look at the basic principles and characteristics of this system.
工業(yè)尾氣脫硝系統(tǒng)采用SCR（Selective Catalytic Reduction）技術(shù)路線對(duì)NOX進(jìn)行處理，其在一定溫度（一般為250℃-450℃）段，在催化劑的作用下可將氮氧化物（NOx）分解成無害的氮?dú)猓∟2）和水（H2O），目前由我司設(shè)計(jì)制作的系列SCR脫硝系統(tǒng)已在多個(gè)領(lǐng)域的眾多項(xiàng)目中成功應(yīng)用。
The industrial tail gas denitrification system adopts the SCR (Selective Catalyst Reduction) technology route to treat NOX. At a certain temperature range (usually 250 ℃ -450 ℃), under the action of a catalyst, nitrogen oxides (NOx) can be decomposed into harmless nitrogen (N2) and water (H2O). Currently, the series of SCR denitrification systems designed and manufactured by our company have been successfully applied in many projects in multiple fields.
工業(yè)尾氣脫硝系統(tǒng)具有體積小、結(jié)構(gòu)簡單、運(yùn)行方便可靠、系統(tǒng)運(yùn)行阻力小、自動(dòng)化程度和脫硝效率高、無二次污染且耐腐蝕性強(qiáng)，整體性能優(yōu)良，一次投資和運(yùn)行費(fèi)用相對(duì)較低等特點(diǎn)，一經(jīng)投入使用，便得到了客戶的充分肯定。
The industrial tail gas denitrification system has the characteristics of small size, simple structure, convenient and reliable operation, low system operation resistance, high automation and denitrification efficiency, no secondary pollution, strong corrosion resistance, excellent overall performance, relatively low primary investment and operating costs. Once put into use, it has been fully recognized by customers.
