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.
The waste heat regeneration adsorption dryer shown in fig. 1 comprises a first drying tower a and a second drying tower B which are arranged in parallel, wherein three pneumatic valve groups connected in parallel are arranged at the upper ends of the two drying towers, two series-connected pneumatic valves 6 are arranged on each pneumatic valve group, an air discharge pipeline 7 is further connected between the two pneumatic valve groups, an exhaust valve 5 is arranged on the air discharge pipeline, and the other pneumatic valve group is connected with an exhaust pipeline 8 of a compressor through a main pipeline 4; the lower ends of the two drying towers are provided with three pneumatic valve groups which are connected in parallel, each pneumatic valve group is provided with two pneumatic valves which are connected in series, the first pneumatic valve group is connected with a silencer 9, the second pneumatic valve group is connected with an exhaust pipeline which is connected with a compressor through a main pipeline, the third pneumatic valve group is connected with a steam cooling and separating system, the steam cooling and separating system is connected with the main pipeline, and the main pipeline is provided with a main control valve 1.
The steam-cooling separation system comprises an after-cooler 2 and a steam separator 3 connected in series with each other. The main control valve, the pneumatic valve group and the exhaust valve are connected with the main controller, and the main controller controls the opening and closing of each valve. A pressure device is arranged in the drying tower. An electric heating compensator in the drying tower.
The process flow is as follows:
the first stage is as follows: hot air from a compressor firstly enters an adsorption tower from the tower top of the tower A for regeneration, then enters a tower B for adsorption after being cooled and separated by a rear cooler and a gas-liquid separator for condensate water, and dry air is discharged from the tower top of the tower B;
and a second stage: after the heating regeneration is finished, hot air from the compressor directly enters the tower B through the rear cooler and the gas-liquid separator for adsorption, and dry air is discharged from the top of the tower B; meanwhile, partial dry air is decompressed through a throttling regulating valve to blow cool the tower A.
And after the blowing cooling is finished, the tower A is pressurized by dry air, then the double towers are switched, the next half period is entered, and the tower AB circularly works under the program control. The exhaust temperature of the compressed air is less than 120 ℃, and an electric heating compensator is additionally arranged to prevent the air from deeply dehydrating the drying agent insufficiently.
The utility model discloses a waste heat regeneration dry adsorption dryer is a novel adsorption dryer, neither belongs to there is the heat regeneration formula, do not belong to heatless regeneration formula yet, and belong to the swing adsorption, it is the heat direct heating regeneration drier that utilizes air compressor machine high temperature exhaust, make the adsorbent obtain the regeneration, even use at 0.35 MPa's low pressure operating mode, as long as the load factor of compressor is not less than 70%, drying device just can work reliably, but consequently make full use of self energy, energy-conserving utility has.
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.
