Describe the embodiment of rotary gas absorption enrichment facility of the present invention below with reference to the accompanying drawings in detail.
Fig. 1 is the encapsulant of following rotary gas concentration unit of the present invention and the cutaway view of mounting portion thereof.Here 1 is encapsulant, and using integrated mica, this integrated mica is with stacked integrated the forming of the shred of mica by binding agent such as silicones.
In the bottom surface 2 of encapsulant 1, promptly with on the face of the end face sliding-contact of cellular rotor 3 be formed with groove 4.And form chamfering 5,6 in the bight of the bottom surface 2 of encapsulant 1 and side.These chamfering 5,6 moving directions (direction of arrow) with respect to cellular rotor 3, and be formed at upstream side.
The 7th, spring presses against encapsulant 1 on the cellular rotor 3 in view of the above.This pushing force can be regulated by nut 8.Nut 8 combines with bolt 9 screw threads.The head of bolt 9 is positioned at groove 4, through encapsulant 1.
So the of the present invention rotary gas absorption enrichment facility that constitutes when making cellular rotor 3 rotations, is input to processed air the treatment region of cellular rotor 3.Contained VOC is adsorbed in the adsorbent of cellular rotor 3 in the processed air.And carry about 180 ℃ desorption air to the desorption district, with the VOC desorption that is adsorbed in the adsorbent.
When the amount of this desorption air be processed air amount 1/10 the time, VOC concentration is concentrated into the concentration of processed air 10 times in the desorption air.The desorption air is by desorption district 14, can be from the desorption district 14 leaks because of encapsulant 1 contacts with the end face of cellular rotor 3.And the bottom surface of encapsulant 1 is formed with groove 4, further prevented leakage according to labyrinth (ラ PVC リ Application ス) effect.
Because the groove 4 of encapsulant 1 forms air trapping, pyroconductivity diminishes, so the heat in desorption district 14 is difficult to pass to other places.Therefore the heat in desorption district 14 seldom is transferred to processed air, thereby can not reduce absorption property.
Under the situation that the end face bending of cellular rotor 3 or rotating shaft tilt, encapsulant 1 moves up and down as shown in Figure 1.That is to say that encapsulant 1 can freely slide up and down with respect to bolt 9, the elastic force of antagonistic spring 7 and rising, perhaps the elastic force owing to spring 7 descends.The pushing force of this spring 7 can be regulated by the nut 8 that combines with bolt 9 screw threads.
