Turn into dry finished product gas after son sieve absorption, exported, realized by output channel after being filtered after valve B2 by outlet filter
It is compressed after functions/drying into compressor secondary inlet.Regenerate flow (regenerative circuit)：
While the second tower is dried, under the control of valve body, by heater 5, recycle compressor compressor 6, gas
Liquid/gas separator 7, cooler 8, the first tower 3-1 form enclosed regenerative circuit.Regeneration gas takes gas from regenerative circuit, i.e. upper one
The regeneration gas come out in regeneration cycle from the second tower enters cooler 8 by valve B3, subsequently into gas-liquid separator 7, then by
The pressurization of recycle compressor 6, which is agitated, flow to electric heater 5, enters the first tower, in the presence of electric heater, temperature by valve A1
Rapid rise, takes heat to first tower, the molecular sieve temperature in tower is raised to a certain extent, separates out adsorbed water
Point, taken away by valve A3 by the high-temperature dry air flowed to cooler 8, temperature is rapidly reduced to 40 DEG C or so, therein
Condensation of moisture Cheng Shui, separated by gas-liquid separator 7, discharged from blowoff valve 10, regeneration gas returns to the (circulation of drying system main entrance
Suction port of compressor).So move in circles certain time, the molecular sieve of saturation water suction is activated regenerating, and possesses adsorption moisture again
Ability.
During regeneration when temperature rise causes to regenerate gas circuit pressure rise, relief valve V1 automatically opens up pressure release according to pressure,
When pressure releasing does not cause safety valve jumping up to relief valve V1, guarantee regenerative system is closed after setting pressure because of superpressure.When again
When angry road is reduced to setting pressure because temperature reduces pressure, pressure charging valve V2 is opened, and is dehydrated gas in main line and is into regeneration
System, ensure that regeneration tolerance is sufficient, when pressure exceedes setting pressure, pressure charging valve is closed.
Natural gas at different levels return inlet buffer during due to compressor shutdown, cause interstage pressure to reduce, to avoid again
Raw system pressure reduces, and regeneration flow need to use closed cycle flow, while set pressure release pressure charging valve, ensure regenerative system between level
Safety and steady operation.
Drier is using double adsorption tower parallel operation modes.When a tower works --- when sloughing the moisture in gas, separately
One tower activating and regenerating, ensures continuous supply, and air supply system occurs without pressure oscillation.All parts of dehydration device are installed concentratedly
On same prying body, unified with pipeline, valve, cable etc., convenience in transport, installation and operation, control.
Referring to Fig. 2, described absorption tower structure includes cylinder 106, and upper cover 105 is provided with the top of the cylinder, should
The top of end socket is provided with molecular sieve charging aperture 101 and air inlet (the gas phase mouth of pipe) 102, and the flange of filter core 103 and air inlet 102 is consolidated
It is scheduled on together, equipped with filter core protection cylinder 104 outside filter core, can prevents molecular sieve from being contacted with filter core.Set in the bottom of the cylinder
Low head 107 is equipped with, the lower section of the end socket is provided with molecular sieve discharge port 111 and bottom gas outlet 110, and bottom filter core 109 is with
The flange of portion gas outlet (the gas phase mouth of pipe) 110 is fixed together, and equipped with filter core protection cylinder 108 outside filter core, can prevent molecule
Sieve contacts with filter core, is conveniently replaceable filter core.During work, gas enters from air inlet 102, by filter core 103 filtering after and gas
Fall moisture into adsorption tower molecular sieve adsorption after uniform, gas dew point is reached less than -60 DEG C, enter by filter core protection cylinder 108
Enter bottom filter core 109 and filter out and tower is gone out by bottom gas outlet 110 after molecular sieve big dust particle.
