Description
Technical field
The utility model is related to the technical fields of drying machine more particularly to a kind of overstable low zero gas consumption air blast of dew point type to add
The technical field of hot absorption drier.
Background technology
The zero gas consumption sorption drying device for producing low dew point compressed air in the prior art is mainly zero gas consumption blast heating
Absorption drier, although compression heat regeneration absorption drier can also realize zero gas consumption, because it is only applicable to centrifugal sky
Press and oilless air compressor, compressed air drag losses are larger, and outlet pressure dew point is poor, therefore by certain in practical application
Limitation.And zero gas consumption blast heating absorption drier compressed air drag losses are smaller, outlet pressure dew point is preferable, but energy consumption
Slightly larger, especially outlet dew point fluctuation is larger.Zero common gas consumption blast heating absorption drier is that commonly having gas consumption drum
On the basis of wind heating reproduction adsorption type drying machine, increase special closed loop and blow what cold program was realized.It is mainly by two absorption
Tower, the adsorbent being arranged in adsorption tower, air blower, heater (electricity, steam or other heat sources), (water is other cold for cooler
Source), connecting pipe valve member, the compositions such as control unit and support construction.During work, a tower adsorption compression moisture in air, separately
One tower carries out the regeneration of internal adsorbent, adsorbent adsorption and desorption cycle operation, so as to constantly produce the compression of low dew point
Air.
The regenerative process of adsorbent can be divided into heating regeneration and blow two stages of cold renewal again.In heating regeneration stage, inhale
Attached dose is sucked by air blower and is heated and removed by the endlessly high temperature positive surrounding air after the heating such as electricity or steam
Moisture, the moisture of removing are finally discharged into regeneration air stream in surrounding air.The cold renewal stage is being blown, is being come out from adsorption tower
High-temperature gas is first cooled down through cooler, then is inhaled into air blower, and absorption of the adsorption tower to high temperature is entered back into after blower
Bed blows cold, blows SAPMAC method so as to form enclosed, regenerator is cooled down by continuously blowing SAPMAC method, is cooled down,
Make the adsorbent bed absorption work for gradually being reached the condition for meeting and being adsorbed by air cooling, being next step in regenerator
It is ready.It is entire regenerate and blow it is cold during, regeneration air source is only surrounding air, does not generate gas consumption, but can consume electricity
Energy and (or) thermal energy.
Due to reaching or close to the upper of normal operating range in low-temperature receiver (such as cooling water or surrounding air) temperature of cooler
When limiting (35 DEG C of 32 DEG C of cooling water temperature or ambient air temperature), cooler is after cooling blow cold air temperature about 40 DEG C (or
42 DEG C), then by blower after, temperature can increase about 15 DEG C, and adsorption bed is carried out into adsorption tower to blow cold gas
Temperature is up to 55 DEG C (57 DEG C), blow it is cold at the end of the temperature of adsorption bed will be at 60 DEG C or more.According to common adsorbent (active oxygen
Change aluminium or molecular sieve) physical characteristic, adsorbent is almost without adsorption capacity at 55 DEG C or more of temperature.In order to keep adsorbing
Formula drying machine outlet compressed air dew point is stablized relatively, it usually needs sets a parallel adsorption process at switching initial stage, i.e.,
Moist compressed air is simultaneously into double tower, and at this moment an adsorption tower adsorption capacity is close to saturation, and another tower is almost without absorption
Ability, as a result, parallel absorption phase, outlet compressed air dew point meeting fluctuation, are adsorbed until in the adsorption tower newly switched
After bed gradually cools down and restores adsorption capacity, outlet dew point can just tend towards stability.

It is shown in Figure 1, adsorption process：Second valve member 10, third valve member 11, the 5th valve member 13, the 8th valve member 16,
Nine valve members 17, the 11st valve member 19 are closed, and the first valve member 9, the 7th valve member 15 are opened, and untreated compressed air enters dry
Dry machine, via the 7th valve member 15 from bottom to top by the first adsorption tower 1, the moisture contained in compressed air is adsorbed by adsorbent,
And dry compressed air then enters gas outlet by the first valve member 9.
Regenerate flow (being carried out at the same time with adsorption process)：Meanwhile another adsorption tower must be ready for adsorbent moisture
The regeneration desorption flow of desorption discharge.This steady flow contains 6 programs：1) pressure release is discharged；2) heating regeneration；3) it blows cold
Regenerate leading portion；4) cold renewal back segment is blown；5) tower body pressure accumulation；6) flows such as preparation state.
1) pressure release discharge flow
During pressure release is discharged, 2 pressure of adsorption tower is via the 6th valve member 14 (the 6th valve member 14 is air bleeding valve) and second exhaust
Compressed air is discharged into air until pressure reaches identical with atmospheric pressure in the second adsorption tower 2 by muffler 8.
2) heating regeneration flow
It is shown in Figure 1, in blast heating regeneration stage, the second valve member 10, the 4th valve member 12, the 6th valve member 14,
Eight valve members 16, the 9th valve member 17, the 11st valve member 19, the 14th valve member 22, the 15th valve member 23, the 16th valve member the 24, the tenth
