Abstract
The present invention is a kind of compressed air drying system, including air compressor machine, freezing type drier, absorption drier and corresponding preposition, postposition and fine filter；Air compressor machine, which exports after compressed air first passes through surge tank and freezing type drier water removal, enters level-one air accumulator, and when ambient air temperature is higher, the exhaust of level-one air accumulator is directly connected to instrument and uses and technique compressed air main pipe；When ambient air temperature is lower, the exhaust of level-one air accumulator is followed by by fine filter and absorption drier to second level air accumulator, then is accessed instrument and used and technique compressed air main pipe.The present invention meets the pressure leak source demand when environment temperature is low of technique compressed air by way of automatically switching drying under the premise of energy-efficient.
Description
Technical field
The present invention relates to compressed air fields more particularly to compressed air to be dried.
Background technique
In industrial project, compressed air humidity requires most common to be -40 DEG C, -20 DEG C and+5 DEG C of pressure leak source respectively.Often
Technique is advised with compressed air pressure dew point by+5 DEG C of requirements, instrument compressed air generally compares work according to HG/T 20510-2014
Make environment or local year (season) extreme minimum temperature is 10 DEG C at least low in history, usually uses -20 DEG C or -40 DEG C.Therefore many
The compression of the method that the compressed air system of industrial project generally uses tertiary treatment to compressed air, i.e. air compressor machine discharge is empty
Gas carries out level-one, second level dehumidification treatments by surge tank and freezing type drier first, pressure leak source is down to 5 DEG C or so, so
Enter technique gas air accumulator afterwards, by picking out in air accumulator all the way to plant area's technique feed channel；It is another after technique gas air accumulator
It connects and is followed by all the way using absorption drier progress three-level dehumidification treatments to instrument gas air accumulator.
Using conventional compressed air system, when environment temperature is high, technique compressed air pipe does not condense, the operation of this system
Normally；When environment temperature is lower than freezing type drier pressure at expulsion dew point, can condense in technique compressed air pipe, though
So technique is influenced it is smaller, but since yard piping is longer, especially with the heavy caliber technique compressed air pipe of carbon steel pipe,
The liquid water of condensation will have an adverse effect to pipeline.
Summary of the invention
Present invention aims at: common compressed air system is adjusted and is optimized, technique compressed air is being reduced
Reduce operation energy consumption in pipeline while moisture condensation to the greatest extent.
The technical scheme is that a kind of compressed air drying system, including air compressor machine, freezing type drier, absorption
Formula drying machine and corresponding preposition, postposition and fine filter；Air compressor machine outlet compressed air first passes through surge tank and freezing type
Enter level-one air accumulator after drying machine water removal, when ambient air temperature is higher, the exhaust of level-one air accumulator is directly connected to instrument use and work
Skill compressed air main pipe；When ambient air temperature is lower, the exhaust of level-one air accumulator is followed by by fine filter and absorption drier
To second level air accumulator, then accesses instrument and use and technique compressed air main pipe.The present invention automatically switch it is dry by way of,
Meet the pressure leak source demand when environment temperature is low of technique compressed air under the premise of energy-efficient.
The medicine have the advantages that system is simple, design, implementation cost are low, reliable for operation, solve under the premise of energy-efficient
The problem of compressed air pipe moisture condensation.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is a kind of schematic diagram of compressed air drying system.
Specific embodiment
The compressed air system of optimization include air compressor machine, freezing type drier, absorption drier and it is corresponding it is preposition,
Postposition and fine filter.Air compressor machine outlet compressed air enters level-one gas storage after first passing through surge tank and freezing type drier water removal
Tank, when ambient air temperature is higher, the exhaust of level-one air accumulator is directly connected to instrument and uses and technique compressed air main pipe；Ambient air temperature
When lower, the exhaust of level-one air accumulator is followed by by fine filter and absorption drier to second level air accumulator, then accesses instrument use
With technique compressed air main pipe.
Compressed air drying process switching method is to automatically switch, and is cut by the motor-driven valve (pneumatic operated valve) on pipeline
It changes.When outdoor temperature is low, absorption drier and pipe valve are automatically turned on, bypass valve is simultaneously closed off；Work as outdoor temperature
When high (specific value is needed according to various regions meteorological condition), absorption drier and pipe valve is automatically closed, opens bypass valve,
It is detailed in Fig. 1.Opening and closing control temperature is determined according to practical local weather condition and freezing type drier exhaust actual pressure dew point.
It is recommended that temprature control method: when temperature on average is higher than 12 DEG C, opening absorption drier and bypass motor-driven valve, close absorbed type drying
Machine；When mean temperature is lower than 8 DEG C, closes absorption drier and bypass motor-driven valve, open absorption drier；Temperature on average between
When between 8~12 DEG C, the method for operation is determined according to minimum temperature, in order to avoid absorption drier frequent start-stop.
