Operationally, three adsorption towers are operated in respectively adsorbed state, thermal regeneration state, cold blowing to the dryer of the present invention
Reproduced state simultaneously switches successively, and by three switch operating states a circulation can be completed, and switches first three with regard to three times below
The operation principle of adsorption tower is made one and is specifically described：
Switch the working condition of first three adsorption tower for the first time：First adsorption tower is operated in adsorbed state, the second adsorption tower
Thermal regeneration state is operated in, and the 3rd adsorption tower is then operated in cold blowing reproduced state.Now the 3rd electrodynamic valve is opened, air inlet pipe
Compressed air entered in the first adsorption tower from the air inlet of the first adsorption tower by the 3rd electrodynamic valve, the moisture of compressed air
Absorbed by the adsorbent in the first adsorption tower, then, dry compressed air flows out from the gas outlet of the first adsorption tower, and passes through
First check-valve is exported from escape pipe, so as to form an independent absorption gas circuit；At the same time, aerator by gas from air-out
Mouth is sent, and compressor now is in running status is opened, and the gas that aerator is sent is partly into heating main, cold in Jing
Thermal regeneration gas is formed after condenser heating；Another part then enters cooling house steward, and cold blowing is being formed again Jing after vaporizer cooling
Angry body.Thermal regeneration gas in heating main is in charge of by the 9th electrodynamic valve opened into the first heating, and by the
Four check-valves are entered in the second adsorption tower from the gas outlet of the second adsorption tower, so as to carry out to the adsorbent in the second adsorption tower
Thermal regeneration.Then, the thermal regeneration gas that temperature is reduced flows out from the air inlet of the second adsorption tower, and by the second of unlatching
Electrodynamic valve flow back into the air inlet of aerator, so as to form the thermal regeneration gas circuit of a closure；In addition, cold in cooling house steward
Blow regeneration gas to be in charge of into the 3rd cooling by the 14th electrodynamic valve opened, and by the 9th check-valves from the 3rd adsorption tower
Gas outlet enter in the 3rd adsorption tower, so as to carry out cold blowing regeneration to the adsorbent in the 3rd adsorption tower.Then, temperature liter
High cold blowing regeneration gas flows out from the air inlet of the 3rd adsorption tower, and flow back into aerator by the 16th electrodynamic valve opened
Air inlet, so as to formed one closure cold blowing regeneration gas circuit.
It is understood that now first, the four, the ten, the 11st, the 12nd, the 13rd, the 15th electrodynamic valve should
It is closed.Further, since the pressure of the compressed air in absorption gas circuit will be far above thermal regeneration gas circuit and cold blowing again
The gas pressure conveyed by aerator in angry road, that is to say, that near the gas outlet side of the first adsorption tower on the 3rd check-valves
Absorption gas circuit gas pressure will be far above near first heating be in charge of side thermal regeneration gas circuit gas pressure, because
This, interior thermal regeneration gas is in charge of in the first heating will not be passed through in the 3rd check-valves stream to the first adsorption tower, and the first absorption
The compressed gas that tower flows out then cannot be entered in the second adsorption tower by the blocking of the 3rd check-valves by the 4th check-valves.With this
In the same manner, the gas pressure of the absorption gas circuit on the 8th check-valves near the gas outlet side of the first adsorption tower will be far above close the
The gas pressure that the cold blowing of side regenerates gas circuit is in charge of in three coolings, therefore, interior cold blowing regeneration gas is in charge of in the 3rd cooling will not
By in the 8th check-valves stream to the first adsorption tower, and the compressed gas that the first adsorption tower flows out then are hindered by the 8th check-valves
It is disconnected to be entered in the 3rd adsorption tower by the 9th check-valves.So, you can absorption, thermal regeneration, cold is formed in dryer
Blow three separate gas circuits of regeneration.
It should be noted that because the gas pressure of the air inlet side of aerator will be less than the gas pressure of air outlet side
Power, that is to say, that in the gas pressure of thermal regeneration and the gas outlet side of second, third adsorption tower of cold blowing reproduced state
The gas pressure of air inlet side is higher than, therefore, the thermal regeneration gas flowed out from the air inlet of the second adsorption tower will not be from
The air inlet of the 3rd adsorption tower is redirected back into in the 3rd adsorption tower, in the same manner, from the cold blowing that the air inlet of the 3rd adsorption tower flows out
Regeneration gas also will not be redirected back into in the second adsorption tower from the air inlet of the second adsorption tower.Thermal regeneration gas and cold blowing are again
Angry body is returned to original temperature after merging, and is then again introduced into the air inlet of aerator to form circulation.
When dryer work certain hour after, need to carry out thermal regeneration to the adsorbent in the first adsorption tower, now I
Should open the three, the four, the nine, the ten, the 12nd, the 14th, the 16th electrodynamic valve, correspondingly close first, second, the
11, the 13rd, the 15th electrodynamic valve, so as to complete for the first time switching, the work that three adsorption towers are entered before switching for second
State.
Switch the working condition of first three adsorption tower for the second time：Now, the 3rd adsorption tower for terminating cold blowing regeneration is switched to
Adsorbed state, the first adsorption tower then enters thermal regeneration state, and the second adsorption tower is then switched to cold blowing reproduced state.For this purpose,
We open the 15th electrodynamic valve, and the compressed air of air inlet pipe is entered by the 15th electrodynamic valve from the air inlet of the 3rd adsorption tower
Enter in the 3rd adsorption tower, the moisture of compressed air is absorbed by the adsorbent of regeneration in the 3rd adsorption tower, then, dry compression
Air flows out from the gas outlet of the 3rd adsorption tower, and is exported from escape pipe by the 5th check-valves, independent so as to form one
Absorption gas circuit；At the same time, the thermal regeneration gas in heating main is heated by the 11st electrodynamic valve opened into the 3rd
It is in charge of, and is entered in the first adsorption tower from the gas outlet of the first adsorption tower by the 8th check-valves, so as to the first adsorption tower
Interior adsorbent carries out thermal regeneration.Then, the thermal regeneration gas that temperature is reduced flows out from the air inlet of the first adsorption tower, and
The air inlet of aerator is flow back into by the first electrodynamic valve opened, so as to form the thermal regeneration gas circuit of a closure；In addition,
Cold blowing regeneration gas in cooling house steward is in charge of by the 13rd electrodynamic valve opened into the second cooling, and by the 6th non-return
Valve is entered in the second adsorption tower from the gas outlet of the second adsorption tower, so as to carry out cold blowing again to the adsorbent in the second adsorption tower
It is raw.Then, the elevated cold blowing regeneration gas of temperature flows out from the air inlet of the second adsorption tower, and the second electrodynamic valve by opening
The air inlet of aerator is flow back into, so as to form the cold blowing regeneration gas circuit of a closure.
Then, dryer needs to carry out thermal regeneration to the adsorbent in the 3rd adsorption tower, now we should open first,
Four, the ten, the 12nd, the 16th electrodynamic valve, correspondingly close second, third, the nine, the 11st, the 13rd, the 14th,
15th electrodynamic valve, so as to complete second switching, the working condition that three adsorption towers are entered before third time switches.
Switch the working condition of first three adsorption tower for the second time：Now, the second adsorption tower for terminating cold blowing regeneration is switched to
Adsorbed state, the 3rd adsorption tower then enters thermal regeneration state, and the first adsorption tower is then switched to cold blowing reproduced state.For this purpose,
We open the 4th electrodynamic valve, and the compressed air of air inlet pipe is entered into by the 4th electrodynamic valve from the air inlet of the second adsorption tower

Phase between the gas outlet of two adsorption towers, the gas outlet of second, third adsorption tower and between the gas outlet of the first, the 3rd adsorption tower
Mutually separate.When we are when switching for the first time is carried out, the 18th electrodynamic valve can be simultaneously opened, so that the first, the 3rd adsorption tower
Gas outlet between be interconnected, so, originally the first adsorption tower in adsorbed state be located in absorption gas circuit be dried it is high
Calm the anger to run through by body and adjust manually flow valve and the 18th electrodynamic valve is entered originally in the 3rd of cold blowing reproduced state the
In the cold blowing regeneration gas circuit that adsorption tower is located, making the gas pressure of the absorption gas circuit of script reduces rapidly, and then we close again
The 18th electrodynamic valve is closed to cut off the contact between absorption gas circuit and cold blowing regeneration gas circuit, so as to complete switching for the first time, you can
Restart to carry out compressed air adsorption dry, and originally the gas in the absorption gas circuit of adsorbed state then can be used as cutting
The regeneration gas in thermal regeneration gas circuit after changing.When we are when second switching is carried out, then the 17th can be simultaneously opened electric
Dynamic valve, so that being interconnected between the gas outlet of second, third adsorption tower, so, originally the 3rd in adsorbed state inhales
Being dried gases at high pressure and can run through in absorption gas circuit that attached tower is located adjust manually flow valve and the entrance of the 17th electrodynamic valve
Originally in the cold blowing regeneration gas circuit that the second adsorption tower in cold blowing reproduced state is located, the gas pressure of the absorption gas circuit of script is made

System, so as to complete second switching.When we are when third time switching is carried out, then the 8th electrodynamic valve can be simultaneously opened, so that
It is interconnected between the gas outlet of first, second adsorption tower, so, absorption that the second adsorption tower in adsorbed state is located originally
In gas circuit be dried gases at high pressure by run through adjust manually flow valve and the 8th electrodynamic valve enter originally in cold blowing again
In the cold blowing regeneration gas circuit that first adsorption tower of raw state is located, making the gas pressure of the absorption gas circuit of script reduces rapidly, so
Afterwards we are re-closing off the 8th electrodynamic valve to cut off the contact between absorption gas circuit and cold blowing regeneration gas circuit, so as to complete third time
Switching.The manual gas flow for adjusting connecting line when flow valve can control switching therein, so as to control three adsorption tower works
Make the switch speed of state.It is understood that adjust flow valve manually only need to be adjusted when dryer runs for the first time, when
Fixed manual adjusts flow valve by after adjusting in place so as to which circulation keeps constant.
In addition, we can also be sequentially connected the 5th electrodynamic valve 505 and air-breathing mistake in the air inlet of aerator by pipeline
Filter 11.So, when we open five electrodynamic valves, the air inlet of aerator is connected with outside air, and outside air can lead to
Cross after suction filter is filtered totally and entered in regeneration gas circuit by the air inlet of aerator, to fill in regeneration gas circuit again
Angry body.The 5th electrodynamic valve is then shut off, suction filter quits work, regeneration gas circuit now re-forms closure gas circuit,
