Machine system.
Background technique
In modern industrial production, compressed air many times can be all used, and has harsh requirement to the quality of gas source,
And wherein common is exactly to water content of compressed air, technical term is known as the requirement of dew point, to get a desired effect, can adopt
It is adsorbed by drying to be conveyed to again on production line after machine equipment is dried with one kind and be used.
Adsorption compressed air dryer is a kind of compressed air cleaning equipment for making compressed air obtain cleaning.It is used
Activated alumina similar in aperture and hydrone diameter is adsorbent, when compressed air flows through, the pressure of moisture in air
Greater than the pressure of hydrone in adsorbent, hydrone, which enters absorbent interior, dries compressed air；Saturation is closed in absorption
It is the regeneration that agent is dried；Upon regeneration, the hydrone in adsorbent is taken away after being purged by dry air, it is vivid
Say to be exactly the process dried up.
And most commonly seen adsorptive drier is heatless regeneration or low-grade fever regeneration dryer, this kind of dryer group is by 2 works
To make tower/tank to constitute, solid alumina desiccant, 2 cone pulley streams are devoted oneself to work, when compressed air flows through first A tower,
While gas is dried, adsorbent is also saturated in gradually water suction, compressed air of another B tower by reference portion after dry,
Account for about the 15% of dry air total amount, carrying out purging keeps adsorbent reactivation dry, for next time using preparing；When first tower
A is adsorbed onto will switch over after a certain period of time: compressed air flows through second B tower and is dried, and blows first A tower
Regeneration is swept, is so constantly recycled.
The switching of two towers, usually using the time control, as soon as such as every progress time rotation in 2 hours, in other words
It is during the work time, always to there is a tower working, another tower is regenerated by purging, on drying effect, professional standard
Usually -40 DEG C of dew points and -80 DEG C of two kinds of dew point designs.
But this traditional adsorptive drier product, it is really needed due to either adsorption process or regenerative process
Time is not fixed, but with condition of production variation, therefore there are apparent energy wastes.

Embodiment one: a kind of adsorptive drier system with dew point control device, as depicted in figs. 1 and 2, including drying
Machine 1, dew point transducer 2 and the control cabinet 3 for controlling drying machine 1 and dew point transducer 2；Dew point transducer 2 is connected to dry
Dry machine 1 exports side；Control module is equipped in control cabinet 3, control module control process includes pressure reduction, regenerative process, liter
Press through journey and adsorption process；Sleep procedure is equipped between boost process and adsorption process.
In above-mentioned implementation process, when drying machine 1 works, the working condition of A tower and B tower is on the contrary, when A tower is in absorption
When process, B tower is in regenerative process, and the time of absorption is related with load, that is, the gas flow/volume and unit bodies pneumatosis flowed through
The water content of body, and actually use in flow through drying machine compressed air require be by produce and use end determines, while and singly
The humidity of position volumes of gas is related, and the gas humidity flowed through is bigger, and the adsorbent in drying machine 1 is easier to be saturated.
Compressed air enters regenerative process after the absorption of drying machine 1 and dries up, the load of the time and absorption that need to dry up
Proportional, the water of absorption is more, and the time that regenerative process needs to purge is also longer, for purging when drying machine 1 regenerates
Dry gas flow is constant.
Increase sleep procedure in regenerative process, i.e., when dew point transducer 2 detects the output gas water content of drying machine 1
When lower than a certain value, the adsorption process of control module control A tower works on, and postpones to execute and change tower movement, and B tower is complete
At regenerative process, be now in sleep procedure, can be no longer consumed compressed air carry out regeneration purge, until dew point transducer
2 detect the output gas dew point of drying machine 1 reach setting dew-point temperature when, just enter change tower movement, suction can be improved in this way
