Description
Technical field:
The utility model relates to the loading and unloading of chemical tanker, relates in particular to a kind of making nitrogen by pressure swing adsorption device.
Background technology:
According to the current market requirement, increasing products tanker, chemical tanker begin installing and rely on power-actuated cargo pump or hydraulically powered cargo pump, load more kinds of goods and pursue and load and unload goods efficient faster.The impurity that contains in common boiler smoke or the inert gas generator is a lot, and kinds of goods are had suitable pollution and after unloading, washing of tanks chronic.And nitrogen gas purity is high, does not contain impurity, and kinds of goods and washing of tanks are had no influence.
Nitrogen gas generator divides two kinds of transformation absorption and membrane sepn, and transformation absorption (being called for short PSA) is to utilize the molecular sieve that is full of small crystal grain that gas molecule is carried out the sky branch technology that selectivity absorbs.Separation principle is that oxygen, the nitrogen adsorption rate on carbonaceous molecular sieve is different, and oxygen is by preferentially adsorbed, and nitrogen obtains from non-absorption mutually.Process step mainly is made up of pressurization absorption, depressurization desorption.Membrane sepn (be called for short Mem) is a difference of utilizing the absorption of all gases in hollow-fibre membrane, diffusion, infiltration rate; Virgin gas gets into the film group of being made up of the up to a million silky tubular fibres of picture human hair; Under the effect of film group external and internal pressure difference; By side direction low pressure outside infiltration in the high pressure, the gas that infiltration rate is big is " fast gas " (oxygen, water) to gas through film, and the gas that infiltration rate is little is " gas slowly " (nitrogen, argon gas).
Transformation absorption early investment cost is high, but maintenance cost is low, when producing higher degree nitrogen, preponderates, and power consumption is low, and shelf life is long; Membrane sepn is not high with respect to transformation absorption early investment cost, needs the periodic replacement gac, electric heater etc.; So maintenance cost is high; When producing than low-purity nitrogen gas, preponderate, power consumption is high, and film is because its organic polymer material has creep; Tunica fibrosa density can increase along with the time gradually, causes that the gas communication resistance strengthens.In operational process, it produces nitrogen amount every year with 5% decrease of speed.
Summary of the invention:
The purpose of the utility model provides a kind of easy to maintenance, and power consumption is low, and long service life makes nitrogen gas purity up to 99.99% making nitrogen by pressure swing adsorption device.
The utility model is to realize like this; A kind of making nitrogen by pressure swing adsorption device comprises air, strainer, oil eliminator, it is characterized in that: described air links to each other with surge tank; The surge tank opposite side links to each other with the freeze drier import; Be provided with strainer between surge tank and the freeze drier import, the freeze drier outlet links to each other with the oil eliminator import, is disposed with fine filter, ultra fine filter between freeze drier outlet and the oil eliminator import; The oil eliminator outlet links to each other with the import of buffering storage tank; The outlet of buffering storage tank links to each other with the import of the transformation adsorption separation system that adsorption tower A, adsorption tower B form, and the outlet of transformation adsorption separation system links to each other with the import of nitrogen buffering storage tank, and the outlet of nitrogen buffering storage tank is provided with dust filter unit.
The utility model is easy to maintenance, and power consumption is low, and long service life makes nitrogen gas purity up to 99.99%.

Embodiment:
Below in conjunction with specific embodiment the utility model is further described:
With reference to accompanying drawing; A kind of making nitrogen by pressure swing adsorption device comprises air 1, strainer 3, oil eliminator 7, it is characterized in that: described air 1 links to each other with surge tank 2; Surge tank 2 opposite sides link to each other with freeze drier 4 imports; Be provided with strainer 3 between surge tank 2 and freeze drier 4 imports, freeze drier 4 outlets link to each other with oil eliminator 7 imports, are disposed with fine filter 5, ultra fine filter 6 between freeze drier 4 outlets and oil eliminator 7 imports; Oil eliminator 7 outlets link to each other with 8 imports of buffering storage tank; 8 outlets of buffering storage tank link to each other with the import of the transformation adsorption separation system that adsorption tower A9, adsorption tower B10 form, and the outlet of transformation adsorption separation system links to each other with 11 imports of nitrogen buffering storage tank, and 11 outlets of nitrogen buffering storage tank are provided with dust filter unit 12.During practical implementation, air to 0.75MPa, is cooled to normal temperature through surge tank through compressor compresses; Separate through strainer fluid again and get into freezing type drier; Flow through fine filter, ultra fine filter and efficient degreasing device except that deoiling and liquid water arrival buffering storage tank, get into the transformation adsorption separation system that the carbonaceous molecular sieve adsorption tower is formed again, after pressurized air gets into from container bottom; Oxygen, carbonic acid gas and moisture are adsorbed agent and select absorption in the air; All the other components (being mainly nitrogen) then flow out from exit end, get into dust filter unit through nitrogen buffer tank, export as product nitrogen gas through filtering nitrogen.Afterwards, processes such as normal pressure are all pressed, are decompressed to the adsorption tower warp, removes adsorbed impurity component, accomplishes the regeneration of carbonaceous molecular sieve.Air is sent in the operation of two adsorption tower cycle alternations continuously, continuously output nitrogen.Nitrogen gets into the nitrogen delivery manifold through metering and nitrogen analyser purity assay back up to standard and supplies use.Said process is controlled by the PLC system automatically.Nitrogen gas purity can be up to 99.99%.Its principle of transformation absorption is to utilize molecular sieve that the difference of gas with various molecule " absorption " performance is separated gaseous mixture; It is to be raw material with the air, utilizes a kind of high-effect, high solid adsorbent of selecting that the performance of the selective adsorption of nitrogen and oxygen is separated airborne nitrogen and oxygen.
