Description
Technical field
The present invention relates to nitrogen production by air separation field, be specifically related to the swing adsorption nitrogen producing apparatus (letter of a kind of alternative film nitrogen
Claim PSA nitrogen-making device).
Background technology
Film separation and nitrogen-making technology be utilize hollow fiber polymer membrane to the gas molecule such as nitrogen and oxygen in air in film molten
Xie Du is different with diffusion coefficient, thus has different infiltration rates, carries out separating by the gas such as nitrogen, oxygen and produces nitrogen or oxygen
The technology of gas.Its advantage: aerogenesis speed is fast, occupation of land space is little, easy to maintenance.Shortcoming: the 1. replacing of the film bucket of film separation and nitrogen-making
Cost is high, relative pressure-variable adsorption, and the requirement that the early stage of air is processed by film bucket is higher, under same gas production, and film separation and nitrogen-making ratio
The cost of PSA nitrogen-making device is high；2. the purity of film separation and nitrogen-making be only applicable to the relatively low occasion of nitrogen gas purity (≤
99.5%), compared to PSA nitrogen-making device, the pressure at expulsion of the air compressor machine of film separation and nitrogen-making prime wants height；3. film bucket service life
Short, general film separation and nitrogen-making device is about 2 years service life, and PSA system with molecular sieve for preparing nitrogen device is about 5-10 service life.
Making nitrogen by pressure swing adsorption technology is to utilize carbon molecular sieve fast in adsorbance, absorption to two or more gas
The difference of the aspects such as degree, absorption affinity, and the characteristic that the adsorption capacity of carbon molecular sieve changes with the change of pressure, adding press strip
Isolate nitrogen under part, be desorbed out tail gas during blood pressure lowering, thus realize gas and separate and the recycling of carbon molecular sieve.PSA system
Nitrogen advantage: technics comparing is ripe, can make the nitrogen of stable about 99.99%-99.999%, and 30 minutes aerogenesis time is left
The right side, service life is long, and maintenance cost is low.Shortcoming: floor space is big, aerogenesis speed is slow, and the method for filling process directly influences
The pulverization situation of molecular sieve, easily causes spray sieve phenomenon.
Summary of the invention
The present invention combines two kinds of nitrogen technical characterstics processed, has invented a kind of alternative film separation and nitrogen-making on the basis of PSA nitrogen
Swing adsorption nitrogen producing apparatus, on the one hand this swing adsorption nitrogen producing apparatus has the advantage of PSA, solves again its floor space big
Shortcoming, the advantage simultaneously having film separation and nitrogen-making concurrently, easy to maintenance.Conventional absorbtion tower is made easily changeable thin tubular, light-duty
Adsorption tower, uses high pressure carbon molecular sieve, screw thread and hose connection, assembles with reference to film bucket compound mode, and a people can complete
Replacing task.PSA nitrogen-making device in the present invention, is made up of absorption tower system, turnover air pipe and valve, ecp system,
Absorption tower system can be made up of Liang Ta, three towers, four towers even multitower.Device can fill difference according to user's requirement in adsorption tower
The molecular sieve of bearing capacity, the quantity adjusting absorption tower system and the quantity of each absorption tower system internal adsorption tower, device can be by
Several absorption tower system compositions, each adsorption tower has independent air inlet, gives vent to anger, drain tap and pipeline and total air inlet, gives vent to anger, arranges
Feed channel is connected, and each adsorption tower all can realize the repair and replacement of single adsorption tower, and the discharge duct of each adsorption tower can be distinguished
Joint noise reduction device, also can connect house steward's deafener, it is achieved modularization assembling, facilitate user to keep in repair replacing.
A feature of the present invention is, adsorption tower uses light metal, highstrenghtpiston or glass fibre equal strength high
Material, can alleviate tower body weight, can meet again the pressure swing adsorption technique under up to 1.6MPa pressure, and adsorption tower volume is less than
0.03m3Or interior diameter is less than 0.15m, according to " safe technology of pressure vessel Supervision Code " and " 2015 up-to-date country special equipments
Catalogue " regulation, the maximum working pressure gas more than or equal to 0.1MPa (gauge pressure), volume is less than 0.03m3And interior diameter
(noncircular cross section refers to cross section inner boundary biggest size of element) container less than 0.15m is vessels not under pressure.The absorption of the present invention
Tower can realize standardization, scale makes, and reduces design and manufacture cost, shortens the production cycle, realizes further in the present invention
The standardization of nitrogen-making device, mass production.This adsorption tower volume is little, and dead space is little, so the utilization rate of adsorbent is high, separately
On the one hand, this adsorption tower volume is little, lightweight, and internal adsorbent is easier to the fine and close consolidation filled, and therefore adsorption tower is permissible
Place vertically, traverse and stacking, reduce the overall volume of nitrogen-making device.
Another feature of the present invention is, the absorption tower system combined with adsorption tower, can by Liang Ta, three towers, four towers very
At most tower composition, improves unstripped gas utilization rate, energy-saving and cost-reducing.
A further feature of the present invention is, can require to fill the molecule that bearing capacity is different according to user in this adsorption tower
Sieve, the highest bearing capacity reaches 1.6MPa, the nitrogen of up to 1.5MPa thus realization is finally given vent to anger, has film separation and nitrogen-making dress completely
Put the advantage that outlet pressure is high.
Accompanying drawing explanation
Fig. 1 is one of two tower structure figures of the present invention.In figure, 1. absorption tower system I II III；The most manual air outlet valve；3. go out
Air pipe；4. product gas supply air line；The most automatically controlled part；6. total air inlet hand-operated valve；7. tower air intake valve about；8. exhaustor

Detailed description of the invention
Three groups of absorption tower system (in figure 1) longitudinal arrangements, each absorption tower system is provided with independent manual air outlet valve (in figure 2)
With independent manual intake valve (in figure 9), device for opening power supply (in figure 5) and total air inlet hand-operated valve (in figure 6), compressed air from
Left and right tower air intake valve (in figure 7) enters absorption tower system left tower absorption, and passing nitrogen is given vent to anger, finally from outlet pipe (figure 3)
Supplying downstream user, simultaneously absorption tower system right tower desorption and regeneration through product gas supply air line (in figure 4), stripping gas passes through exhaustor
Road (in figure 8) is discharged through deafener (in figure 10), and after a circulation, left and right tower switches, and left tower desorption and regeneration, right tower absorbs
Gas, so circulates.
