The present invention is used for from the compressed air containing a large amount of vaporous waters for drying compressor output, finally again by once mistake
Filter, so as to ensure to provide cleaning dry compressed air for Vehicular system.The compression to match with the double-tower dryer of the present invention
Machine discharge capacity can be selected in 1000L/min or so, air drag ＜ 50KPa.
The operation principle of the present invention：The both ends of first drying 1 are respectively arranged with the first input port 20 and the first delivery outlet 22,
The both ends of second drying 2 are respectively arranged with the second input port 21 and the second delivery outlet 23, and user can be according to being actually needed freedom
Selection uses the first input port 20, the first delivery outlet 22, the second input port 21 and the second delivery outlet 23, both can be simultaneously using described
Input port and delivery outlet, it is possible to use the part input port and delivery outlet, while by without using the input port and output
Mouth is sealed by plug.
For convenience of description, it is now assumed that only connecting the second input port 21 and the second delivery outlet 23, the first input port 20 and first
Delivery outlet 22 is sealed by plug.
When the air inlet of the second input port 21, by the second air intake valve 6, usual second air intake valve 6 is opening, air-flow
Output is to the second drying 2, and for the second drying 2 built with the metal tube and molecular sieve of flow-disturbing, air-flow is in first uniform shape through flow-disturbing
State, secondly it is dried through the molecular sieve, is filtered again through filter paper, then passes through middle gas tube and reach second check-valve
Door 8, when air pressure reaches certain value, second check-valve door 8 is opened, and air-flow reaches the second delivery outlet 23, and it is defeated so far to complete air-flow
Go out.
A part of air-flow in the air-flow that above-mentioned completion is dried passes through the pipeline shunt of the second delivery outlet 23 to pre-control valve 18
Lower end, the outer end of pre-control valve 18 are provided with small-sized filter element, and when 18 times end pressures of pre-control valve reach certain value, valve is beaten
Open, now air-flow just reaches the lower end of second solenoid valve 16, is opened if second solenoid valve 16 is powered, and air-flow reaches the second intake valve
The unlatching chamber for closing chamber and the piston of second exhaust valve 12 of 6 pistons of door, now the second air intake valve 6 close, second row air valve
Door 12 is opened, regeneration air stream discharge.
The air-flow dried by the second drying 2, before second check-valve door 8 is reached, a portion airflow diversion
To the first drying 1, after the splitting streams from bottom to top move to top by the intermediate conduit of the first drying 1, then by
Molecular sieve upper end in first drying 1 reaches first to its lower end motion after the water adsorbed in the molecular sieve is blown out
Drain tap 11, and discharged by first row gas port 24, the regeneration gas consumption that the splitting streams can reach different by changing latus rectum
The design requirement of amount.
Controller 17 can control the energization and power-off of the first magnetic valve 15 and second solenoid valve 16, when second solenoid valve 16
During the opening that is powered, the second air intake valve 6 of the second drying 2 is closed, and second exhaust port 25 is opened, now the second drying
2 are in regenerating molecular sieve state without drying.Otherwise function is as the same when the first magnetic valve 15, which is powered, to be opened.Controller 17
Mode of operation can optimize design for circuit and being actually needed for Functional Design according to different user.
When the temperature that temperature sensor 19 monitors reaches the start-up temperature value of setting, controller 17 instructs secondary heater
10 start to start, and when reaching the stopping temperature value of setting, controller 17 instructs secondary heater 10 to be stopped.
First pressure sensor 13 and second pressure sensor 14 are used to monitor the first magnetic valve 15 and second solenoid valve 16
Mode of operation it is whether normal, that is, be used to judge switching working mode between the first drying 1 and the second drying 2 whether just
Often.
When secondary heater 10 is in normal operating conditions, if first pressure sensor 13 or second pressure sensor
The situations such as 14 mode of operations exception, the switching working mode exception of the first magnetic valve 15 and second solenoid valve 16, current anomaly go out
Now, controller 17 can send related different abnormal signal in time to the external world, to take correlation technique measure to give in time
Effectively to exclude.
The controller 17 of the present invention has store-memory function, when in real work in the presence of needing to analyze, judging situations such as
When, can read the net cycle time of this double-tower dryer by controller 17, the first magnetic valve 15 and second solenoid valve 16 it
Between the total degree that switches, and its content such as job information details in longer one section of work period.
When air pressure be present in the drying, the push rod of the pressure indicator can eject；Do not have when in the drying
When having air pressure, the push rod of the pressure indicator can retract automatically, be generally used for identifying the first drying 1 and the second drying 2
Working condition, it can also be used to when carrying out the dismounting and change work of the first drying 1 and the second drying 2, it is ensured that dismounting is more
The safety to change jobs.
