一、制氮機工作原理
制氮(dan)(dan)(dan)(dan)機的(de)(de)(de)(de)原(yuan)理(li)主(zhu)(zhu)要有三種(zhong):1、PSA變(bian)壓吸(xi)附制氮(dan)(dan)(dan)(dan)原(yuan)理(li):用(yong)(yong)碳(tan)分子篩作為(wei)吸(xi)附劑,設計科(ke)學的(de)(de)(de)(de)工藝(yi)流程,利(li)用(yong)(yong)變(bian)壓吸(xi)附的(de)(de)(de)(de)原(yuan)理(li)制取氮(dan)(dan)(dan)(dan)氣(qi)(qi)(qi):基于(yu)碳(tan)分子篩對(dui)(dui)(dui)氧和(he)(he)(he)氮(dan)(dan)(dan)(dan)的(de)(de)(de)(de)吸(xi)附速(su)率不同,碳(tan)分子篩優先吸(xi)附氧氣(qi)(qi)(qi),碳(tan)分子篩本身具有加(jia)壓時對(dui)(dui)(dui)氧氣(qi)(qi)(qi)的(de)(de)(de)(de)吸(xi)附容量(liang)增加(jia),減壓時對(dui)(dui)(dui)氧的(de)(de)(de)(de)吸(xi)附量(liang)減少的(de)(de)(de)(de)特(te)性,利(li)用(yong)(yong)這種(zhong)特(te)性實現氧氣(qi)(qi)(qi)和(he)(he)(he)氮(dan)(dan)(dan)(dan)氣(qi)(qi)(qi)的(de)(de)(de)(de)分離,得到我們所需要的(de)(de)(de)(de)氮(dan)(dan)(dan)(dan)氣(qi)(qi)(qi)。2、深冷空(kong)(kong)(kong)分制氮(dan)(dan)(dan)(dan)原(yuan)理(li):深冷空(kong)(kong)(kong)分制氮(dan)(dan)(dan)(dan)是(shi)(shi)一種(zhong)傳統的(de)(de)(de)(de)制氮(dan)(dan)(dan)(dan)方法,它是(shi)(shi)以空(kong)(kong)(kong)氣(qi)(qi)(qi)為(wei)原(yuan)料(liao),經過壓縮(suo)、凈化,再利(li)用(yong)(yong)熱交換使空(kong)(kong)(kong)氣(qi)(qi)(qi)液化成為(wei)液態,液態空(kong)(kong)(kong)氣(qi)(qi)(qi)主(zhu)(zhu)要是(shi)(shi)液氧和(he)(he)(he)液氮(dan)(dan)(dan)(dan)的(de)(de)(de)(de)混合物,利(li)用(yong)(yong)液氧和(he)(he)(he)液氮(dan)(dan)(dan)(dan)的(de)(de)(de)(de)沸點不同(在1大(da)氣(qi)(qi)(qi)壓下,前者的(de)(de)(de)(de)沸點為(wei)-183℃,后者的(de)(de)(de)(de)為(wei)-196℃),通(tong)過精(jing)餾(liu),使它們分離來獲得氮(dan)(dan)(dan)(dan)氣(qi)(qi)(qi)。3、膜(mo)空(kong)(kong)(kong)分制氮(dan)(dan)(dan)(dan)原(yuan)理(li):膜(mo)空(kong)(kong)(kong)分制氮(dan)(dan)(dan)(dan)是(shi)(shi)利(li)用(yong)(yong)高分子中空(kong)(kong)(kong)纖維膜(mo)對(dui)(dui)(dui)空(kong)(kong)(kong)氣(qi)(qi)(qi)中氮(dan)(dan)(dan)(dan)和(he)(he)(he)氧等(deng)氣(qi)(qi)(qi)體(ti)分子具有不同的(de)(de)(de)(de)滲(shen)透速(su)率,將氮(dan)(dan)(dan)(dan)跟氧等(deng)氣(qi)(qi)(qi)體(ti)進行分離而制取高純度氮(dan)(dan)(dan)(dan)氣(qi)(qi)(qi)。

三、制氮機多少錢一臺
制(zhi)氮(dan)(dan)機的價(jia)(jia)格(ge)一般受(shou)到(dao)型(xing)號規格(ge)、處(chu)理(li)能力、生產(chan)氮(dan)(dan)氣(qi)的純度、配置(zhi)功(gong)能、生產(chan)廠家等因素影響,小型(xing)制(zhi)氮(dan)(dan)機價(jia)(jia)格(ge)在(zai)(zai)幾千(qian)元一臺(tai)到(dao)上萬(wan)(wan)元甚至(zhi)幾萬(wan)(wan)元一臺(tai)左右,一些高端的小型(xing)氮(dan)(dan)氣(qi)機具(ju)有高精(jing)度、高純度、低噪音等特(te)性,價(jia)(jia)格(ge)也會相應更高。中型(xing)制(zhi)氮(dan)(dan)機(處(chu)理(li)能力在(zai)(zai)10-100 Nm3/h)的價(jia)(jia)格(ge)大約為數(shu)(shu)萬(wan)(wan)至(zhi)十多萬(wan)(wan)元;而大型(xing)制(zhi)氮(dan)(dan)機(處(chu)理(li)能力超(chao)過100 Nm3/h)的價(jia)(jia)格(ge)可能達(da)到(dao)數(shu)(shu)十萬(wan)(wan)元甚至(zhi)更高。
四、制氮機廠家怎么選
在選購制氮機時,應綜合考慮生產的氮氣純度需求、產氮量需求、露點需求、環境條件、設備投資與運行成本,選擇適合的產品,除此之外還要注意制氮機廠家的選擇:1、了解廠家實力:選擇制氮機廠家時,首先要了解廠家的實力。查看廠家的資質、技術水平、生產能力等方面,確保廠家具備生產高質量制氮機的能力。同時,了解廠家的規模和經營狀況,確保廠家具備穩定的生產和供貨能力。2、比較產品性能:選擇制氮機廠家時,要對其產品進行比較。了解不同廠家的制氮機性能參數、技術特點和使用效果等方面的信息,以便更好地選擇適合自己需求的制氮機。同時,要注意選擇技術成熟、品質可靠的制氮機產品。3、考察服務質量:除了產品本身的質量,廠家的服務質量也是選擇廠家時需要考慮的重要因素。了解廠家的售后服務體系、維修保養能力等方面的情況,確保在使用過程中能夠得到及時的技術支持和維修保養服務。4、參考用戶口碑:用戶口碑是選擇制氮機廠家時的重要參考依據。通過搜索網絡、行業論壇等渠道了解用戶對不同廠家的評價和口碑,以便更好地選擇合適的廠家。同時,要注意甄別虛假評價和廣告宣傳,確保獲取的信息真實可靠。如果您不太了解,可以先來看看制氮機十大品牌。
