目前常用的氮氣供應方法有:瓶裝氮氣運送,液態(tài)氮氣運送,管道輸送,深冷分離,PSA變壓吸附分離,VPSA真空解析分離,膜分離。
At present, the commonly used nitrogen supply methods include bottled nitrogen transportation, liquid nitrogen transportation, pipeline transportation, cryogenic separation, PSA pressure swing adsorption separation, VPSA vacuum analytical separation and membrane separation.
一,確定流程,首先要知道,一般我們通常使用瓶裝氮標準瓶容積約為40L,含有氮和氧含量的6nm3,和經(jīng)常使用的用戶只4.5-5nm3實際數(shù)額,其余的是沒有打出去,原因是為了讓用戶供應廠家煤氣燈,每次洗瓶,但也有一定的關(guān)系,你首先需要知道你整天與氣缸內(nèi)氣體的數(shù)量,然后用光的多少小時,氣缸內(nèi)的氣體,如果使用10瓶氣,是光10小時,該你每小時約1瓶,一瓶的數(shù)量在5m3重量。因此,流量應選擇5m3/小時。
1、 To determine the process, first of all, we need to know that generally, we usually use bottled nitrogen. The standard bottle has a volume of about 40L and contains 6nm3 of nitrogen and oxygen content. The actual amount is only 4.5-5nm3 for users who often use it. The rest is not called out because they want users to supply the manufacturer's gas lamp and wash the bottle every time, but it also has a certain relationship, You first need to know the amount of gas in the cylinder all day, and then how many hours you use up. If you use 10 bottles of gas, it is light for 10 hours. You should have about 1 bottle per hour, and the amount of one bottle is 5M3. Therefore, the flow shall be 5M3 / hour.
二,測定其純度,一般來說,氣缸內(nèi)的氣體會對純潔,你只需要看看自己的意志,如果沒有概念,你有同伴,或設(shè)計院,制氮機制造商咨詢具體的純度,這要根據(jù)具體的使用氮的關(guān)系。
2、 To determine its purity, generally speaking, the gas in the cylinder will be pure. You only need to look at your own will. If there is no concept, you have a companion, or a design institute, or a manufacturer of nitrogen making mechanism to consult the specific purity, which should be based on the specific relationship between the use of nitrogen.
三,選型,目前幾種氮方法有自己的優(yōu)點,但PSA的市場份額高,其次是空氣分離設(shè)備,然后真空變壓吸附氮氣,這要根據(jù)具體的量和純度,如果量大,純度高99.99%以上),比如1000立方以上,就可以選擇深冷,若比這個小,純度低90%以上,)建議選擇PSA變壓吸附式制氮機,若純度較低,流量大,可選擇VPSA真空解析,但膜分離,市場上基本上已經(jīng)不用了。
3、 At present, several nitrogen methods have their own advantages, but PSA has a high market share, followed by air separation equipment, and then vacuum pressure swing adsorption of nitrogen, which depends on the specific amount and purity. If the amount is large and the purity is more than 99.99%), for example, more than 1000 cubic meters, you can choose cryogenic. If it is smaller than this, the purity is more than 90%, )It is recommended to select PSA pressure swing adsorption nitrogen generator. If the purity is low and the flow is large, VPSA vacuum analysis can be selected, but membrane separation is basically not used in the market.
