Specific embodiment
For realizing above-mentioned technical purpose, big flow adjustable steady and continuous compressed air gas source system of present invention design
Including helical-lobe compressor, compressor distribution system, refrigerant type dryer, filter, air accumulator, pipe-line system, cooling circulating water
The part such as pump, blower fan system, valve system, temperature and pressure transmitter, central control system is constituted.
Described screw compressor supplies 17, and single compressor maximum stream flow is 84.7Nm3/ min, maximum exhaust pressure
Power 0.75MPa, compressor rated voltage 6kv, rated power 500kw.Although screw compressor flow is little, with centrifugal pressure
Contracting machine is compared, and screw compressor aerofluxuss are uniform and stable continuous it is adaptable to this project trial zone requires relatively to compressed air quality
High situation.
Described compressor distribution system is located at high-tension distribution chamber of converting, and predominantly compressor provides reliable and stable power supply, protects simultaneously
Card safety, high tension distribution system includes middle high-voltage switch gear switch board, air compressor machine soft-start cabinet, air compressor machine compensating cabinet.
Described blower fan system mainly considers that number of compressors is excessive, and Factory Building normal circulation is not enough to provide so big uses gas
Amount.Using opening rolling screen door and start the method that combines of blower fan and to meet maximum gas consumption.
The compressed air that compressor is discharged mainly is filtered, is dried, simultaneously by totally 7 groups of described refrigerant type dryer, filter
Every group of cooling driers also play certain cushioning effect to the compressed air of the compressor generation of this group.
Described air accumulator mainly trial zone valve do not open or gas consumption very little in the case of, by air pipe line
Compressed air introduces air accumulator storage and plays certain cushioning effect.
Described pipe-line system includes compressed air line, inlet pipeline, water return pipeline.
Totally 3, cooling water circulation water pump, every maximum stream flow of design is 400Nm3/min.Compressor, cooling driers equipment are
Water-cooling type, takes away, using recirculated water, the heat producing when equipment runs.It is cold that water circulating pump and inlet pipeline, water return pipeline are constituted
But water circulation system ensure that normal cooling and the use of equipment.
Valve system is including electric butterfly valve, handss valve.Valve is predominantly located on pipeline, and every group of inlet pipeline is arranged
One electric butterfly valve facilitates remote activation, and on every group of water return pipeline, one handss valve of setting is convenient overhauls；Every group of air branch line
One electric butterfly valve of local setting being connected with air maim to adjust compressed air require and pressure；Every compressor and cold
In the water inlet of dry machine and water return pipeline, handss valve is set, convenient maintenance；Additionally, air accumulator and trial zone entrance setting electric butterfly valve are each
One.
Temperature and pressure transmitter is arranged on compressed air gas source system needs the key area of monitoring, such as every group of air arm
Road compressed air pressure, trial zone compressed air pressure, air accumulator compressed air pressure, cooling water supervisor's inflow temperature, cooling
Water supervisor's return water temperature, cooling water supervisor's air pressure, cooling water supervisor's air pressure etc..
Central control system is located between observing and controlling, and main inclusion operates software interface and video monitor.Operation software interface base
In LabVIEW software development, to be controlled and supervision equipment for core using the S7-300 series of PLC in Factory Building；Video is supervised
Control by 8 high-definition tripod photographic head in Factory Building come real-time monitoring Factory Building state, and monitoring information in 30 days can be inquired about.
The operation principle of this patent is such：The normal air providing with blower fan in Factory Building is absorbed by compressor, passes through
Compression within compressor, oil-water separation etc. enter air bye-pass, and the compressed air of air bye-pass is thick through prefilter
After filtration, enter cooling driers dry decontamination process after, through fine filter filter after enter air maim import air accumulator or
Person is directly entered trial zone；Meanwhile, recirculated water is incited somebody to action through water circulating pump and inlet pipeline entrance compressor, cooling driers equipment
Heat takes away it is ensured that equipment normal work, and cooling water enters water circulating pump circulation after water return pipeline and cooling tower cooler and makes
With.Central control system is controlled and supervision equipment for core by S7-300 series of PLC simultaneously, real with operation software communication
The existing function such as remote operation, monitoring, storage, record, warning.
17 compressors are divided into 7 groups, and every group configures 1 cooling driers and some compressors, wherein configures 1 compressor
1 group (numbering group 1) of 1 cooling driers, 2 groups (numbering group 2, groups 3) of configuration 21 cooling driers of compressor, 3 compressions of configuration
4 groups (numbering group 4, group 5, group 6, groups 7) of 1 cooling driers of machine.Every compressor maximum extraction flow is 84.7Nm3/ min,
Big pressure at expulsion 0.75MPa.
Under normal operating condition, only need to input 1400 in host computer operation interface, system can calculate automatically, in all screw rods
Formula compressor be all turned on after can when maximum stream flow can be provided to reach 1400Nm3The compressed air of/min, then system prompt behaviour
After work person confirms, start air compressor machine, cooling driers, finally realize flow and reach 1400Nm3The compressed air of/min uses for trial zone.
So it is achieved that the maximum gas supply flow 1400Nm of compressed air gas source3/min.
Compressed air gas source system is controlled using packet, arranges in pairs or groups to adjust flow by opening different groups, only need to be
The gas supply flow that operation interface input needs, system automatically selects corresponding group, opens after confirming, finally realizes
Gas supply flow is adjustable.Through calculating, in air supply system each group, group 1 gas supply flow is 84.7Nm3/ min, group 2, group 3 gas supply flows
For 170Nm3/ min, group 4, group 5, group 6, group 7 gas supply flows are 254Nm3/min.For example input 1000Nm in operation interface3/
Min, system calculates automatically, group 4, group 5, group 6, group 7 simultaneously open or group 4, group 5, group 6, group 7 any open three groups add group
1st, group 2 (also or group 1, group 3) meets the requirements, and after operator confirms to open machine group, starts associated compressors, cold dry
Machine, compression within compressor, oil-water separation etc. enter air bye-pass, and the compressed air of air bye-pass is through prefilter
After coarse filtration, after entering the process of cooling driers dry decontamination, enter air maim after fine filter filters and import air accumulator
Or it is directly entered trial zone, finally realize flow and reach 1000Nm3The compressed air of/min uses for trial zone.Thus permissible
That realizes compressed air gas source flow automatically adjusts characteristic.
