Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, the micro-thermal regeneration adsorption dryer includes a first drying tower a and a second drying tower B which are arranged in parallel, a pneumatic valve set connected in parallel is arranged at the upper end of each drying tower, and an exhaust pipeline 6 is arranged between the two pneumatic valve sets; the drying tower is characterized in that a regenerated gas pipeline 9 is further arranged at the upper part of the drying tower, a heater 5 is arranged on the regenerated gas pipeline, the heater is connected with a gas source 10 through a regenerated gas inlet pipe, and the drying tower further comprises a regenerated gas regulating valve 7 arranged on the regenerated gas inlet pipe; the lower ends of the two drying towers are provided with two paths of pneumatic valve groups which are connected in parallel, each pneumatic valve group is provided with two pneumatic valves 3 which are connected in series, the first path is connected with a silencer 4, the other path is connected with a wet air pipeline 1, and the wet air pipeline is provided with a main control valve 2.
The exhaust pipeline is connected with the regeneration air inlet pipe through an air return pipe, and the air return pipe is provided with a control valve 8. The main control valve, the pneumatic valve group, the regenerated gas regulating valve and the control valve are all connected with a main controller, and the main controller controls the opening and closing of each valve. A pressurizing device is arranged in the drying tower. An electric heating compensator is arranged in the drying tower.
The process flow is as follows:
and (3) drying: wet air enters the tank A through a lower pipe and an A1 valve, flows through the adsorbent bed from bottom to top, and dried air is discharged from an exhaust pipe.
Regeneration: the dry air from the air source or the exhaust pipe is decompressed through a regeneration regulating valve and then enters a heater for heating, the air enters a tank B, the adsorbent in the tank B is analyzed and regenerated, the drying capacity of the adsorbent is recovered, and the adsorbent is discharged into the atmosphere through a B1 valve and a silencer of a lower pipe system. After the adsorption regeneration is finished, the valve B1 is closed, the pressure in the tank B is gradually increased to the online working pressure, and the switching is accurate. The lower pipeline system B2 valve is opened, the A1 valve is closed, the A2 valve is opened, the A, B two drying tanks are switched, the tank B enters the adsorption, and the tank A is decompressed and regenerated.
The above description is only an example of the preferred embodiment of the present invention, and is not intended to limit the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
