Abstract
The utility model discloses a PSA (pressure swing adsorption) nitrogen manufacturing system for ships, and is characterized in that the system comprises an air compressor, wherein, a C-class filter is arranged behind the air compressor, a cooling and drying machine is arranged behind the C-class filter, a T-class filter and an A-class filter are arranged in sequence behind the cooling and drying machine, an adsorption tower device is arranged behind the A-class filter, and the nitrogen retention side of the adsorption tower device is connected with a nitrogen storage tank. The utility model has the advantages of reasonable structure and good performance.
Description
Technical field:
The utility model relates to a kind of nitrogen gas generating system peculiar to vessel.
Background technology:
Existing nitrogen-making device peculiar to vessel, complex structure, service behaviour is undesirable, is difficult to satisfy the demand.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, the marine pressure varying adsorption nitrogen making system of favorable working performance.
Technical solution of the present utility model is:
A kind of marine pressure varying adsorption nitrogen making system, it is characterized in that: comprise air compressor, C level filter is set behind the air compressor, behind the C level filter cooling driers is set, set gradually T level filter, A level filter behind the cooling driers, behind the A level filter adsorption tower device is set, the nitrogen of adsorption tower device is detained side and is connected with the nitrogen storage gas tank.
Air compressor is a screw air compressor, and every power is 132KW.
The pressure-swing absorber device is combined by two adsorption towers.
The utility model is rational in infrastructure, favorable working performance, and major advantage:
1, cost is low: a kind of simple method for preparing nitrogen of transformation absorption advanced technologies, and start back a few minutes generation nitrogen, energy consumption is low.
2, dependable performance: microcomputerized control, full automatic working, need not the operating personnel of special training, only need press starting switch, just can turn round automatically, reach the function of continuous production nitrogen.
3, nitrogen gas purity is stable, and safety is shown by instruments monitor, guarantees required nitrogen gas purity.
4, adsorption tower is selected high-quality import carbon molecular sieve for use: have that adsorption capacity is big, compressive property is high, the unique advantage of long service life.
5, high-quality by-pass valve control: the special-purpose operated pneumatic valve of the import of high-quality can guarantee that the equipment of making nitrogen reliablely and stablely turns round.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the configuration diagram of an embodiment of the utility model.
The specific embodiment:
A kind of marine pressure varying adsorption nitrogen making system, comprise air compressor 1, C level filter 2 is set behind the air compressor, behind the C level filter cooling driers 3 is set, set gradually T level filter 4, A level filter 5 behind the cooling driers, behind the A level filter adsorption tower device is set, the nitrogen of adsorption tower device is detained side and is connected with nitrogen storage gas tank 9.The pressure-swing absorber device is combined by two adsorption towers 6,7.
Air compressor is a screw air compressor, and every power is 132KW.Also has air reservoir 8 among the figure.
Air compressor machine satisfies the traffic requirement of system for system provides system nitrogen required raw material.Purifier mainly is made up of filter and cooling driers, and filter C level purifies moisture bigger in the compressed air and contaminant filter earlier, and the compressed air that one-level is filtered by cooling driers cools off again, makes it meet the optimum temperature of transformation absorption; The compressed air that comes out from cooling driers further purifies micro particle filtering littler the compressed air through filter T level and filter A level again, meets the air inlet requirement of pressure-swing absorber; Compressed air up to standard passes through pressure-swing absorber again, is adsorbent with the carbon molecular sieve, adopts the transformation adsorption process, under normal temperature low pressure, utilizes airborne oxygen different with nitrogen diffusion rate in carbon molecular sieve, and oxygen is separated with nitrogen.The oxygen of enrichment is discharged in the atmosphere, and nitrogen is delivered to air accumulator, is sent in each cabin by the deck distribution system.
