節(jié)能高壓制氮機（G型）

此款節(jié)能高壓型制氮機為一體機系統。即內置全無油壓縮機，經冷凍干燥機及三級過濾器除去油水、粉塵顆粒，經預處理后的無油干燥空氣進入二組制氮吸附器進行氧氮分離，一級吸附，一組脫附，連續(xù)生產出合格的氮氣送至氮氣緩沖罐，當氮氣緩沖罐壓力達到設定壓力時，停止制氮機組，切換至增壓系統開始增壓氮氣，氮氣緩沖罐壓力下降到設定值時停止增壓，又開始制氮運行，從而連續(xù)不斷的產出高壓氮氣。氮氣壓力可高達1 .5MPa-30Mpa,。

該機型的運行狀態(tài)為“全自動運行"（無需人為操作設備的啟停），空氣進品、氮氣出口設有過濾調壓部件，內置冷凍干燥機及C、T、A三級過濾器、自動排水器。PC控制系統選用西門子主機。氮氣純度由99.99 -99.999%氮氣分析儀在線檢測，氮氣純度不合格自動排空并報警，合格氮氣輸出后達到設定壓力白動停機。節(jié)省空壓機能耗達10%-30%不等。制氮吸附塔交替運行排空時，加裝有快速排空裝置，以達到制氮工藝快速脫附要求，延長了工藝電磁閥的使用壽命。

The energy-saving nitrogen making machine of high pressure uses an all-in-one system, that is, built-in oil-free compressor. Firstly, freezing and drying machine and three-stage filter are used to remove grease, dust particles. After preprocessed, the oil-free dry air is pushed into two groups of nitrogen adsorb machines to separate hydrogen and nitrogen. While one group adsorbing, the other group stripping, continuous qualified nitrogen is produced to nitrogen buffer tank. When nitrogen buffer tank's pressure reaches to set value, nitrogen generating unit stops and instead pressurization system starts charging nitrogen. When the nitrogen gas buffer tank pressure drops to the set point, it is supposed to stop charging and begin the operation of nitrogen making, thereby continuously outputting high pressure nitrogen whose pressure can be up to 1. 5 Mpa - 30 Mpa.

Running state of the machine is "automatic operation" (that is, without the need for operating the start-stop of the equipment). Air inlet and nitrogen outlet are equipped with pressure regulating components, the built-in refrigeration dryer and C, T, A three-stage filter and automatic drainage device. Siemens host is used in PC control system. Nitrogen purity is monitored by analyzer on-line, by 99.99-99.999% unit. Automatic emptying and alarm are set if the purity of nitrogen is unqualified, and the system will automatically stop when it reaches the set pressure after qualified nitrogen output, thus, saving the air compressor power consumption by up to 10-30% range. Altemately emptying system of nitrogen adsorption tower, with a rapid emptying device, in order to achieve rapid stripping requirements in nitrogen making process, prolongs the life of electromagnetic valve.
