Description
Technical field
The present invention relates to a kind of oxygenerator multicomputer associating variable load operation device and method.
Background technology
In recent years, financial crisis made every profession and trade production capacity occur superfluous phenomenon ubiquity.Maximize more and more while universalness at oxygenerator, how adapt to the change of user's oxygen, nitrogen product demand fast, realize not only quick adjustment load but also run with stabilizing the economy become gas generation enterprise whether can the key factor of sustainable development under severe economic situation.
Content of the present invention
In order to play the overall operating performance of oxygen making unit, reduce energy consumption, for subsequent use, raising system reliability each other, the invention provides a kind of oxygenerator multicomputer associating variable load operation device and method.
To achieve these goals, the present invention adopts following technical scheme:
A kind of oxygenerator multicomputer associating variable load operation device, comprises air compressor machine, purification and distillation system, ice chest, oxygen compressor, nitrogen compressor; The supporting air compressor machine of two or more each oxygenerators is increased series valve in exit; Two or more oxygenerator oxygen, nitrogen output channel are accessed respective pipe network respectively, realize being connected into any oxygen compressor of pipe network or nitrogen compressor and all can extract gas in respective pipe network, and each oxygenerator exit all sets out ice chest hand-operated valve, to guarantee that stoppage in transit oxygenerator excises out pipe network system.
Described purification and distillation system are by air precooling system, and molecular sieve, decompressor, main heat exchanger, subcooler, main distillation column, argon column forms.
Described oxygenerator compressed air serial pipe and series valve are arranged between each air compressor machine outlet valve and air cooling tower inlet valve.
The Size estimation of described two or more oxygenerator can be different.
A kind of oxygenerator multicomputer associating variable load operation method, in oxygenerator running, when vibrating the faults such as excessive or motor power failure and having to shut down appears in air compressor machine on the one hand, can the air compressor machine of another oxygenerator for subsequent use of emergency start, this oxygenerator can return to normal operating conditions at short notice and produce qualified oxygen, nitrogen product; On the other hand all oxygen making unit oxygen, nitrogen output channel are accessed pipe network respectively, when the oxygen compressor run or nitrogen compressor break down and stop, oxygen compressor for subsequent use or nitrogen machine can be started immediately, avoid and the impact brought is produced on subsequent user, ensure that safety and stability supply.
Described air compressor machine raw air is sent in rectifying column by compression the power-equipment participating in rectifying.
Described nitrogen compressor and oxygen compressor make it reach the equipment of the pressure needed for user by compression the low oxygen of oxygenerator output and nitrogen.
The operation principle of oxygenerator all adopts cryogenic refrigeration method: raw air, after air compressor machine compression, enters air precooling system and is cooled to temperature≤18 DEG C, then enters molecular sieve purifier absorption and falls carbon dioxide in air and residual steam; Divide two-way afterwards, a road major part air reaches at main heat exchanger and the gas converting heat that backflows and to enter tower under rectifying column after close to air liquefaction temperature, and another road enters on rectifying column after booster expansion turbine pressuring expansion; After rectifying, product oxygen is drawn from upper tower bottom, and after re-heat, cooling box enters oxygen compressor and carries out compressing and being sent to user; Product nitrogen gas is drawn from upper top of tower, and after re-heat, cooling box enters nitrogen compressor and carries out compressing and being sent to user.Each for two or more oxygenerator supporting air compressor machine is increased series valve in exit, realizes raw air and switch online, for subsequent use each other, power generating ratio number of times; Two or more oxygenerator oxygen, nitrogen output channel are converged access and form respective gas products pipe network, realize output channel networking, reach any oxygen compressor of being connected into pipe network or nitrogen compressor and all can extract medium in pipe network, for subsequent use each other, improve the object of compressibility reliability.
Beneficial effect of the present invention:
1. when in an oxygenerator running, vibrating the faults such as excessive or motor power failure and having to shut down appears in air compressor machine; can the air compressor machine of another oxygenerator for subsequent use of emergency start; this oxygenerator can return to normal operating conditions at short notice and produce qualified oxygen, nitrogen product; if and employing starts the way of another whole oxygenerator for subsequent use; from startup air compressor machine to heating, hydrops finally adjusts pure; to the time relatively grown be needed, the production of subsequent user certainly will be affected.
2. all oxygen making unit oxygen, nitrogen output channel are accessed pipe network respectively, when the oxygen compressor run or nitrogen compressor break down and stop, oxygen compressor for subsequent use or nitrogen machine can be started immediately, avoid and the impact brought is produced on subsequent user, ensure that safety and stability supply;
3. with a 15000Nm
3/ h oxygenerator and a 20000Nm
3/ h oxygenerator is example, on the one hand, and 20000Nm
3/ h oxygenerator heat before driving compressed air consumption in process less time, can 15000Nm be used
3the supporting air compressor machine of/h oxygenerator provides compressed air to heat, and this saves a part of power consumption; On the other hand, when subsequent user oxygen is by 20000Nm
3/ h oxygenerator runs consumption when can reach the equilibrium of supply and demand and drops to 15000Nm suddenly
3/ h and following scale, at this moment by the online switching of the supporting air compressor machine of two or more oxygenerator, make 20000Nm
3/ h oxygenerator, 75% and following load operation, had both avoided and had started 15000Nm
3product-free energy consumption in/h oxygenerator start-up course, again need not because of 20000Nm
3/ h oxygenerator overlaps load when air compressor machine provides compressed air first wife to be reduced and limitedly causes that supply exceed demand, a large amount of Oxygen venting causes waste, realize the regulatory function that oxygenerator separate unit surpasses design underload, unit minimum load can be reduced to 40%, achieves energy-saving and cost-reducing object.
