The pressure drop: 0.03 MPa or less
Control system: SIEMENS PLC
Scope of application:
Must be with oil free (centrifugal, oil-free screw air compressor.
Gas consumption:
Work under the standard conditions (pressure 0.7 MPa, inlet temperature of 120 ℃, cooling water temperature 35 ℃)
When the PDP = - 20 ℃
Gas consumption is zero;
Performance characteristics:
1, which can realize the dew point pressure range is extensive; - 20 ℃ ~ 70 ℃
2, reliable performance and stable pressure dew point;
3, is the current blot machine inside the most energy-efficient products.
4, complicated structure, pneumatic valves require high temperature resistant level.
5, equipment investment cost is high.
Structure features:
1, adsorption bottom special "lotus layout" diversion structure, no dead corner area, to ensure uniform air distribution.
2, the bottom loading ceramic balls, make air flow distribution more uniform; Which can effectively prevent the lower adsorbent bubble water, agglomerate, prolong the service life of the adsorbent.
3, selects the high performance of pneumatic butterfly valve, 304 stainless steel to take over; Valve position indicator + signal feedback
4, choose efficient WS gas water separator: compact structure, reduced pressure, stable and reliable running, separation efficiency > 99%
5, choose the back of the cooler, high efficiency and reliable interpolation disturbing piece of strengthening heat transfer; Make the inlet and outlet of the cooling water temperature can reach 7 ℃, can effectively reduce energy consumption by 10%
6, advanced control system
LDCS load control loops:
By measuring the regeneration/cooling temperature, automatic control of heating/cooling blowing time; Load decreases, can shorten the time, reduce the regeneration gas consumption.
Dew point control loop DPOS:
On the basis of load control, through the dew-point meter control adsorption time. Load falls, according to the dew point to extend the time of adsorption performance, and reduce the average each cycle regeneration gas consumption.
With Siemens PLC:
With nearly/remote control; 4 ~ 20 mAh signal
By RS485, the I/O interface to upload to DCS, realize the centralized control
(Profibus and Modbus, Ethernet communications can be customized)
Has a fault alarm and protection function, can realize the unattended
Programs take power off memory function, maintain the current state of valve position
All valves, real-time monitoring state, when the valve is damaged or abnormal movements,
Automatic alarm, and enter standby mode
