一、制氮機工作原理
制(zhi)(zhi)(zhi)(zhi)氮(dan)(dan)機(ji)的(de)(de)(de)原(yuan)理(li)主(zhu)(zhu)要有三種(zhong):1、PSA變(bian)壓吸附制(zhi)(zhi)(zhi)(zhi)氮(dan)(dan)原(yuan)理(li):用(yong)碳分子篩作為(wei)(wei)吸附劑,設計(ji)科學(xue)的(de)(de)(de)工(gong)藝流(liu)程,利用(yong)變(bian)壓吸附的(de)(de)(de)原(yuan)理(li)制(zhi)(zhi)(zhi)(zhi)取(qu)氮(dan)(dan)氣(qi):基于碳分子篩對氧(yang)(yang)(yang)和(he)(he)氮(dan)(dan)的(de)(de)(de)吸附速率不同,碳分子篩優先吸附氧(yang)(yang)(yang)氣(qi),碳分子篩本身具有加壓時對氧(yang)(yang)(yang)氣(qi)的(de)(de)(de)吸附容量增(zeng)加,減(jian)(jian)壓時對氧(yang)(yang)(yang)的(de)(de)(de)吸附量減(jian)(jian)少的(de)(de)(de)特性,利用(yong)這種(zhong)特性實現氧(yang)(yang)(yang)氣(qi)和(he)(he)氮(dan)(dan)氣(qi)的(de)(de)(de)分離,得到我們(men)所需要的(de)(de)(de)氮(dan)(dan)氣(qi)。2、深冷(leng)空(kong)(kong)(kong)分制(zhi)(zhi)(zhi)(zhi)氮(dan)(dan)原(yuan)理(li):深冷(leng)空(kong)(kong)(kong)分制(zhi)(zhi)(zhi)(zhi)氮(dan)(dan)是一種(zhong)傳統的(de)(de)(de)制(zhi)(zhi)(zhi)(zhi)氮(dan)(dan)方法,它(ta)是以空(kong)(kong)(kong)氣(qi)為(wei)(wei)原(yuan)料,經過壓縮、凈(jing)化,再利用(yong)熱交換使(shi)空(kong)(kong)(kong)氣(qi)液(ye)(ye)(ye)化成為(wei)(wei)液(ye)(ye)(ye)態,液(ye)(ye)(ye)態空(kong)(kong)(kong)氣(qi)主(zhu)(zhu)要是液(ye)(ye)(ye)氧(yang)(yang)(yang)和(he)(he)液(ye)(ye)(ye)氮(dan)(dan)的(de)(de)(de)混(hun)合物(wu),利用(yong)液(ye)(ye)(ye)氧(yang)(yang)(yang)和(he)(he)液(ye)(ye)(ye)氮(dan)(dan)的(de)(de)(de)沸點(dian)不同(在1大(da)氣(qi)壓下,前者的(de)(de)(de)沸點(dian)為(wei)(wei)-183℃,后者的(de)(de)(de)為(wei)(wei)-196℃),通過精餾,使(shi)它(ta)們(men)分離來(lai)獲得氮(dan)(dan)氣(qi)。3、膜空(kong)(kong)(kong)分制(zhi)(zhi)(zhi)(zhi)氮(dan)(dan)原(yuan)理(li):膜空(kong)(kong)(kong)分制(zhi)(zhi)(zhi)(zhi)氮(dan)(dan)是利用(yong)高(gao)分子中空(kong)(kong)(kong)纖維膜對空(kong)(kong)(kong)氣(qi)中氮(dan)(dan)和(he)(he)氧(yang)(yang)(yang)等氣(qi)體分子具有不同的(de)(de)(de)滲透速率,將氮(dan)(dan)跟(gen)氧(yang)(yang)(yang)等氣(qi)體進行(xing)分離而制(zhi)(zhi)(zhi)(zhi)取(qu)高(gao)純度氮(dan)(dan)氣(qi)。

三、制氮機多少錢一臺
制氮機(ji)的價格一(yi)(yi)般受到型(xing)(xing)號規格、處理能力(li)、生產氮氣的純度(du)、配(pei)置功能、生產廠家等因素影(ying)響,小型(xing)(xing)制氮機(ji)價格在(zai)幾(ji)千元一(yi)(yi)臺到上萬(wan)元甚(shen)至幾(ji)萬(wan)元一(yi)(yi)臺左右,一(yi)(yi)些高端的小型(xing)(xing)氮氣機(ji)具有高精度(du)、高純度(du)、低噪音等特性,價格也(ye)會相應更(geng)高。中(zhong)型(xing)(xing)制氮機(ji)(處理能力(li)在(zai)10-100 Nm3/h)的價格大(da)約為數(shu)萬(wan)至十多(duo)萬(wan)元;而大(da)型(xing)(xing)制氮機(ji)(處理能力(li)超(chao)過100 Nm3/h)的價格可能達到數(shu)十萬(wan)元甚(shen)至更(geng)高。
