目前常用的氮气供应方法有:瓶装氮气运送,液态氮气运送,管道输送,深冷分离,PSA变压吸附分离,VPSA真空解析分离,膜分离。
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,确定流程,首先要知道,一般我们通常使用瓶装氮标准瓶容积约为40L,含有氮和氧含量的6nm3,和经常使用的用户只4.5-5nm3实际数额,其余的是没有打出去,原因是为了让用户供应厂家煤气灯,每次洗瓶,但也有一定的关系,你首先需要知道你整天与气缸内气体的数量,然后用光的多少小时,气缸内的气体,如果使用10瓶气,是光10小时,该你每小时约1瓶,一瓶的数量在5m3重量。因此,流量应选择5m3/小时。
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,测定其纯度,一般来说,气缸内的气体会对纯洁,你只需要看看自己的意志,如果没有概念,你有同伴,或设计院,制氮机制造商咨询具体的纯度,这要根据具体的使用氮的关系。
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,选型,目前几种氮方法有自己的优点,但PSA的市场份额高,其次是空气分离设备,然后真空变压吸附氮气,这要根据具体的量和纯度,如果量大,纯度高99.99%以上),比如1000立方以上,就可以选择深冷,若比这个小,纯度低90%以上,)建议选择PSA变压吸附式制氮机,若纯度较低,流量大,可选择VPSA真空解析,但膜分离,市场上基本上已经不用了。
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.
