本技術(shu)涉及一種基于(yu)嵌入式管道電解固氮裝置(zhi),屬于(yu)等離(li)子設(she)備(bei)。
背景技術:
1、波(bo)克蘭-艾德(de)(birkeland-eyde,b-e)法與(yu)哈伯-博施(haber-bosch,h-b)法是工業(ye)化(hua)大規模固(gu)氮(dan)的2種代(dai)(dai)表(biao)性(xing)方法。b-e法主要(yao)是在空氣(qi)中(zhong)通過電弧,即熱等(deng)離子體,將(jiang)氮(dan)氣(qi)與(yu)氧氣(qi)轉化(hua)為(wei)(wei)no與(yu)no2,再將(jiang)no2吸收進水(shui)中(zhong)產生hno3。該(gai)方法能量效(xiao)率與(yu)轉化(hua)率都很低,且對反應條件(jian)要(yao)求較(jiao)為(wei)(wei)嚴格,故在工業(ye)化(hua)生產中(zhong)逐(zhu)步被h-b法取代(dai)(dai)。
2、h-b法是由n2與h2在200個大(da)(da)(da)氣(qi)壓與400℃的(de)(de)(de)(de)條件下,采用鐵(tie)催化劑(ji)合成(cheng)(cheng)氨的(de)(de)(de)(de)工(gong)(gong)藝(yi),目(mu)前仍然(ran)是世界上最(zui)主要的(de)(de)(de)(de)合成(cheng)(cheng)氨工(gong)(gong)藝(yi),每年通過該方法生(sheng)(sheng)產的(de)(de)(de)(de)氨氣(qi)總量(liang)超過1.3億t。然(ran)而,h-b法需(xu)要在高溫高壓的(de)(de)(de)(de)苛刻反(fan)應條件下進(jin)行,能(neng)耗較高,每年通過h-b法生(sheng)(sheng)產氨消耗的(de)(de)(de)(de)能(neng)源占全(quan)球總能(neng)源消耗的(de)(de)(de)(de)1%~2%。其次(ci),該反(fan)應是可逆的(de)(de)(de)(de),反(fan)應過程(cheng)會(hui)釋放(fang)大(da)(da)(da)量(liang)熱能(neng),當生(sheng)(sheng)產規模足夠大(da)(da)(da)時工(gong)(gong)業生(sheng)(sheng)產才較為經(jing)濟。此外,傳(chuan)統h-b法會(hui)排放(fang)大(da)(da)(da)量(liang)的(de)(de)(de)(de)co2等溫室(shi)氣(qi)體(ti)(ti)以及其他有害氣(qi)體(ti)(ti),對全(quan)國(guo)乃至全(quan)球的(de)(de)(de)(de)大(da)(da)(da)氣(qi)環境造(zao)成(cheng)(cheng)嚴(yan)重的(de)(de)(de)(de)破(po)壞(huai)。
3、在20世紀,相關學(xue)者提出在兩(liang)電(dian)(dian)極間施(shi)加(jia)高電(dian)(dian)壓(ya),產生強(qiang)電(dian)(dian)磁場(chang)使(shi)氣(qi)體分子解離(li),產生大氣(qi)壓(ya)等(deng)(deng)離(li)子體,并利用該技術進行固(gu)氮(dan)。經過數十年的發(fa)展,大氣(qi)壓(ya)等(deng)(deng)離(li)子體固(gu)氮(dan)技術日(ri)趨成熟。根(gen)據(ju)反應裝置的不同,可以將等(deng)(deng)離(li)子體發(fa)生形式分為介質阻擋(dang)放(fang)電(dian)(dian)(dielectric?barrier?discharges,dbd)、微波放(fang)電(dian)(dian)、射流放(fang)電(dian)(dian)、火花放(fang)電(dian)(dian)與滑動弧放(fang)電(dian)(dian)等(deng)(deng)。
4、專利(li)cn115532198a提供一種管道嵌入式(shi)放(fang)(fang)(fang)電(dian)等離子體液相(xiang)固氮(dan)(dan)(dan)裝(zhuang)置及其固氮(dan)(dan)(dan)方法,采用(yong)(yong)(yong)管道嵌入式(shi)放(fang)(fang)(fang)電(dian)固氮(dan)(dan)(dan)。該技術存在(zai)以(yi)下的(de)技術問題(ti):1、本裝(zhuang)置使用(yong)(yong)(yong)的(de)火花(hua)(hua)放(fang)(fang)(fang)電(dian)產生(sheng)火花(hua)(hua)放(fang)(fang)(fang)熱因此能(neng)量未被充(chong)分利(li)用(yong)(yong)(yong);2、本裝(zhuang)置采用(yong)(yong)(yong)火花(hua)(hua)放(fang)(fang)(fang)電(dian)不(bu)能(neng)對(dui)通入氣(qi)(qi)(qi)體進行充(chong)分反應;3、經過處理后的(de)氣(qi)(qi)(qi)體往(wang)往(wang)以(yi)氮(dan)(dan)(dan)氧化(hua)物氣(qi)(qi)(qi)體形(xing)式(shi)通入水中,不(bu)能(neng)被充(chong)分吸收利(li)用(yong)(yong)(yong)。
