Operation instruction is carried out to the system of non heated regeneration dryer of the present embodiment below：
After compressed air first passes around cooler cooling, then it is in satiety to remove 99% or more through gas-liquid separator and oil expeller
With the liquid grease of state, enter drier in the compressed air of saturation state.Water vapour molecule pressure in compressed air compared with
Height, when the adsorbent very low with surface water vapour molecule pressure contacts, the water vapour molecule in compressed air is just to adsorbent
Surface is shifted, and the water vapour molecule pressure of adsorbent surface is gradually increased, and the water vapour molecule pressure in compressed air is gradual
It reduces, and tends to balance, that is to say, that the water vapour molecule in compressed air enters inside adsorbent, to make compressed air
Drying is obtained, this is the adsorption drying process under normal pressure.About 12% drying finished product gas is used as regeneration (under 0.8MPa operating modes)
Gas, after the decompressional expansion that throttles, the water vapour molecule pressure of regeneration gas further decreases, and is encountering former moisture absorption in regenerator
, the adsorbent that steam partial pressure is relatively high when, the steam partial pressure of regeneration gas gradually rises, and adsorbent surface
Steam partial pressure continuously decreases, and the hydrone of adsorbent surface is gradually released until balance, i.e., the water in adsorbent steam
It is attached that vapour molecule is reproduced aspiration, and air is discharged in company with regeneration gas in hydrone, and to make adsorbent obtain dry regeneration, here it is normal
Depress adsorbent desorption and regeneration process.Above-mentioned adsorption drying process and adsorbent desorption and regeneration process are circular flow.
In the present embodiment, first by 10 the first valves 61 of unlatching of program controller, the compressed air of temperature≤40 DEG C is passed through
Compressed air inlet pipe 8, the first valve 61 enter in the first drying tower 1 carries out adsorption drying process first, and will be after drying
Finished product compressed air successively through in finished product gas circuit first check-valve 31 and finished product gas delivery pipe 5 be discharged, and it is real by program controller 10
When the flow of finished product compressed air that is discharged through first check-valve 31 of monitoring, when the finished product compressed air of discharge account for always generate at
Product compressed air 88% when, controlled by program controller 10 and close first check-valve 31, while opening regeneration gas regulating valve 4, will remained
The finished product compressed air of remaining 12% is discharged into through regenerating gas circuit in the second drying tower 2 as regeneration gas, in the second drying tower 2
Moisture absorption, adsorbent that steam partial pressure is relatively high carry out adsorbent desorption and regeneration；Regeneration gas in second drying tower 2
Steam partial pressure gradually rises, and adsorbent surface steam partial pressure continuously decreases, and the hydrone of adsorbent surface is gradual
It is released until balance, it is attached that the stream molecule in adsorbent is reproduced aspiration, and adsorbent is made to obtain dry regeneration, hydrone
In company with regeneration gas air is discharged into through the 4th valve 72, regeneration gas delivery pipe, exhaust silencer 9 successively.Equipment continues to run with, and passes through
The second valves 62 of unlatching of program controller 10, by the compressed air intake duct 8 of the compressed air of temperature≤40 DEG C, the second valve 62 into
Enter and carry out adsorption drying process in the second drying tower 2, and by the finished product compressed air after drying successively through the in finished product gas circuit
Two check-valves 32 and finished product gas delivery pipe 5 are discharged, and monitor the finished product pressure being discharged through second check-valve 32 in real time by program controller 10
The flow of contracting air is controlled when the finished product compressed air of discharge accounts for the 88% of the finished product compressed air always generated by program controller 10
System closes second check-valve 32, while opening regeneration gas regulating valve 4, using remaining 12% finished product compressed air as regeneration gas
Through regenerate gas circuit be discharged into the first drying tower 1, to the moisture absorption in the first drying tower 1, steam partial pressure it is relatively high
Adsorbent carries out adsorbent desorption and regeneration；The steam partial pressure of regeneration gas gradually rises in second drying tower 1, and adsorbent table
Face steam partial pressure continuously decreases, and the hydrone of adsorbent surface is gradually released until balancing, and the water in adsorbent steams
It is attached that vapour molecule is reproduced aspiration, so that adsorbent is obtained dry regeneration, hydrone is in company with regeneration gas successively through third valve 71, regeneration
Gas delivery pipe, exhaust silencer 9 are discharged into air.It is taken turns to operate by the first drying tower 1 and the second drying tower 2, alternate cycles are dry
Dry absorption and regeneration two processes of desorption are improving compressed air drying degree simultaneously so that the adsorbent in drying tower obtains
100% regeneration.
After adsorbent uses 1~2 year, it need to all release and be screened, the adsorbent of drying tower lower part about 1/3 is discharged
Should not, because these adsorbents are broken and pollute more serious, screening reuse only is carried out to 2/3 adsorbent on drying tower top.Sieve
When selecting, feeding port 11 and discharge port 12 are unscrewed, adsorbent flows out automatically from discharge port 12, after all drawing off, spins discharging lid,
The adsorbent drawn off is poured into through feeding port 11 with funnel, the adsorbent after screening is as lower layer, then again through feeding port 11
New adsorbent is injected in upper layer until being full of, and spins filler lid.After drier starts operation 2~3 hours, adsorbent
It can be sunk, need to be supplemented loading, the replacement cycle is depending on the specifically used operating mode of equipment and using effect.
It can be seen that the system of non heated regeneration dryer of the present embodiment is simple in structure, easy for installation, pass through the first drying tower and
Two drying towers take turns to operate, alternate cycles drying absorption and regeneration two processes of desorption so that the adsorbent in drying tower obtains
100% regeneration can reduce regeneration gas consumption while improving regeneration gas aridity, reduce the row of energy waste and exhaust gas
Go out, improves the drying efficiency of compressed gas；Meanwhile system of non heated regeneration dryer automatically controls the keying of each valve by program controller,
The automation cyclic process for realizing dry absorption and regeneration desorption, improves work efficiency.
