Embodiment：
With reference to each accompanying drawing, the utility model is described in detail.
The utility model discloses a kind of absorption drier (see accompanying drawing 1,2,3,4), including：At least one pair of absorption regeneration
Tower 1, it is used to adsorb air to prepare dry air or regeneration in turn；The absorption regeneration tower 1 is provided with negative pressure regeneration exhaust
Pipeline 3, the negative pressure regeneration exhaust pipeline 3 are provided with vavuum pump 4, and the negative pressure regeneration exhaust pipeline 3 connects absorption regeneration tower
1, for keeping air pressure relatively low in absorption regeneration tower 1.The utility model is arranged on absorption drier plus negative pressure regeneration gas
Air pipe, upper vavuum pump 4 is then connected, for taking out the gas in regenerator, to reach negative pressure regeneration；Reach and 1) reduced regeneration
Gas consumption amount 0.5-1.1%；2) pressure in the tower of regeneration is -0.02~-0.04mpa (subatmospheric power 0mpa) 3) regeneration
Effect is good, and adsorbent water-taking efficiency is higher, the more low technique effect of dew point.
The absorption drier also includes regeneration gas discharge duct 7, and the regeneration gas discharge duct 7 connects negative pressure again
Raw gas exhaust piping 3.The absorption drier also includes compressed air inlet pipe road 2, the both ends of compressed air inlet pipe road 2
Connection regeneration gas discharge duct 7 side by side.
The absorption drier also includes air releasing silencer 5, and the air releasing silencer 5 is arranged on regeneration gas discharge duct

Unqualified gas discharges into air；
Equipment starts, the regeneration of another absorption regeneration tower；When another absorption regeneration tower regenerates, regeneration gas passes through again
Raw pipeline enters another absorption regeneration tower, when another absorption regeneration tower switches to regeneration by adsorbing, due to another suction
Attached regenerator has residual 0.4mpa or so gas due to just completing adsorption process in another absorption regeneration tower, due to
Gases at high pressure can not be discharged into vavuum pump, therefore controller controls corresponding operated pneumatic valve, first allows gases at high pressure to pass through silencer
Moment is expelled in air (evacuation time is about 2-6S), when gas is 0mpa in another absorption regeneration tower, controller control
The air releasing silencer of system exhaust is closed, then the operating of controller control vavuum pump, and regeneration gas stream is by the emptying on vavuum pump
Silencer is discharged, and equipment carries out negative pressure regeneration.
