Description
Technical field
The utility model relates to Compressor Technology, improves instrument supply gas compressor dew point device particularly to one.
Background technology
The Automated condtrol production fields such as petrochemical industry, iron and steel, chemical industry, the coming into operation of various raw materials in production process, and middle
The quality control of process product, is required for automatic control device.Automated condtrol executing agency (control valve) be regulation and
The most frequently used equipment that control produces, in order to control the device of fluid flow, pressure and the flow direction.
Now many using instrument air as the control source of Automated condtrol executing agency and power source.Instrument air cleaning,
Environmental protection, safety, low cost, meanwhile because of the demand to control accuracy, have higher wanting to the dew point and cleannes of instrument supply gas
Ask.In the occasion under condensation temperature for the exposed tube of conveying air, dew point is particularly significant, and high dew point may result in pipeline to be freezed
And blocking.Compressed air is used for operating various equipment, if forming Water vapor condensation on inner body, then some of them equipment can
Fault can be there will be.Instrument air dew point≤-30 DEG C are typically required in technique.
Existing air outlet pressure after helical-lobe compressor reaches 670Kpa, sends into and be dried after tentatively filtering through filter
Device, is dried to the moisture in instrument supply gas in drier.Drier in drier need to be regenerated by blowback air, and determines
The replacing of phase.Dried instrument supply gas is sent in buffer and is stored, and delivers to each user.Manual sampling analysis, instrument at buffer
Whether the dew point of table gas is qualified.
More for south rainwater, with the change in season, the humidity difference of air is very big, and factory is located proximate to river
Limit, these factors can cause process units, and the particularly duty of drier has greatest differences.In drier absorption in rainy season
Moisture is more, the activating and regenerating to drier, and by the pressure regeneration of blowback air, the time of activation increases, and activation efficiency is not good yet,
Drying to instrument supply gas is just insufficient.At plum rain season, the underproof situation of instrument supply gas dew point is apparently higher than other seasons.
Utility model content
The purpose of this utility model is to design a kind of instrument supply gas compressor dew point device that improves, and solution is because of air humidity relatively
Greatly, Various Seasonal difference is obvious, and same technique is different to dew point after instrument supply gas process.And winter is due to outdoor environment temperature relatively
Low, in equipment pipe compressed air moisture condensation frozen block pipeline, causes gas circuit not smooth, causes entirely stand pneumatic instrument, pneumatic tune
The problems such as joint valve events is inaccurate.
For reaching above-mentioned purpose, the technical solution of the utility model is:
A kind of raising instrument supply gas compressor dew point device, comprising: buffer, its import connects compressor by pipeline and goes out
Mouth pipeline；Two driers, are arranged in parallel, and are arranged in parallel first, second connection pipeline, the firstth, between the entrance point of two driers
Respectively arranging two control valves on second connection pipeline, wherein, on the first connection pipeline, the pipeline between two control valves is connected to described
The export pipeline of buffer, the second connection pipeline arranges blow-down pipe on the pipeline between two control valves；The outlet of two driers
It is arranged in parallel third and fourth between end and connects pipeline, third and fourth connection pipeline respectively arranges two control valves, wherein, the 4th connecting tube
On road, the pipeline between two control valves is connected to instrument air house steward；On 3rd connection pipeline, two check-valves are set；Heater, its
Inlet ductwork connects two dryer export ends the 3rd and connects the pipeline between two check-valves on pipeline；The export pipeline of heater sets
Put a control valve.Online dew point hygrometer and some control valves are set on described instrument air house steward；Controller, described online dew point
Instrument, heater and second connection pipeline on two control valves, the 4th connection pipeline on two control valves and described heater outlet pipeline
On control valve be all electrically connected with this controller.
To instrument supply gas pressurization reflation pretreatment, (ability that air accommodates steam is inversely proportional to the utility model with pressure, rises
Air after pressure puffing again is to atmospheric pressure, and the change of this pressure makes expanded air become more to be dried).Instrument supply gas dew point is entered
Row monitoring in real time.Reheat to by the instrument supply gas after drier.Because different seasons changes the duty of heater.
Rely on the real-time monitor value to instrument supply gas dew point, adjust heater.
Air outlet pressure after helical-lobe compressor reaches 670KPa, through buffers store buffering, then through at the beginning of filter
Step sends into drier after filtering, and is dried the moisture in instrument supply gas in drier.Drier in drier need to pass through
Blowback air regenerates, and does and regularly change.Blowback air can be heated by heater, in conjunction with the activation of pressure type blowback drier.
Installing online dew point hygrometer sending gas port, on-line analysis detects, and delivers to each user after dew point is qualified.
Compared with prior art, the utility model has the advantage of:
1st, prior art is using buffer as storage device, and buffer of the present utility model can be used as buffer use,
Can also play buffering and reduce the effect of instrument supply gas temperature, air is after helical-lobe compressor compression, and instrument supply gas temperature raises, and can lead to
The cushioning effect crossing buffer reduces instrument supply gas temperature, makes moist part contained in instrument supply gas be condensate in bottom buffer, can
Got rid of by drain valve.
2nd, prior art carrys out activated desiccant by the pressure differential of blowback air, and the utility model increases online dew point hygrometer detection dew newly
Point situation, by increase heater, according to instrumentation gas dew point value control heater work, when dew point can meet require when,
Directly going out pneumatic transmission, when dew point deflects away from and arranges scope, blowback air is heated by heater, the blowback air activation effect after heating
Rate substantially increases, and drier recovers to be dried adsorption function.Instrument supply gas is again after drier, and dew point is qualified to be sent.
3rd, prior art armrest moves sample analysis instrument supply gas dew point, the uncontrollable and real-time prison of the drying effect of drier
Survey.The utility model installs online dew point detector, by real-time monitoring dryer export instrument supply gas dew point, control heater and
The work of drier, forms closed loop regulation, can ensure that and adjust according to different weathers, the duty of heater and drier,
The instrument supply gas dew point making output is qualified.
