The flow process of this commercial car air dryer vibration regenerative drying chamber is as follows:
Gas to be dried from air compressor machine is flowed into by the one-level turbulent flow hole 2 of circumferentially arranging, and because one-level turbulent flow hole 2 is expanding round platform pore structures, realization to be dispersed the first time of air-flow and speed slows down.Gas to be dried is with turbulent condition by filtering material 4 afterwards, and through the secondary turbulent flow hole 6 on secondary turbulent flow block 5, the second time realizing gas to be dried is dispersed and the slowing down of speed; Because one-level turbulent flow hole 2 and secondary turbulent flow hole 6 are staggered at an ang, the direction of motion of air-flow will change, and the second time of gas to be dried when secondary turbulent block 5 is dispersed and slowed down effect with speed and will obviously strengthen.Gas to be dried enters Edge molecular sieve 7 afterwards, realizes fully contacting with the first time of desiccant material; After passing Edge molecular sieve 7, gas will flow out from edge pressure strip 9, arrive the bottom of drying chamber inner bag, and be passed by three grades of turbulent holes 11 on three grades of turbulent blocks 12, and the third time realizing gas to be dried disperses and the slowing down of speed; Gas enters middle element sieve 14 afterwards, realizes fully contacting with the second time of desiccant material.Gas fully contacts owing to sieving 7 with Edge molecular before, sieve 14 abundant contact dryings again with middle element after, through the drying again of filter membrane 15, will be discharged by exhaust structure 16, its drying effect has met use standard, will flow to regeneration air tank and other dynamical system respectively.
During desiccant material regeneration, the flow direction of gas is completely contrary with dry run.When purge gas inflow middle element sieves 14, gas flow rate is larger, the dividing plate spring damping device that three grades of turbulent blocks 12 and middle holddown spring 11 form can make middle element sieve 14 generation up-down vibration and produce dispersion, improves the regeneration effect of desiccant material.When purge gas inflow edge molecular sieve 7, the dividing plate spring damping device that secondary turbulent flow block 5 and edge holddown spring 3 form also can produce same effect.
Secondary turbulent flow block 5 and edge pressure strip 9 two ends arrange the version of edge holddown spring 3 and edge compressing structure 10 respectively, both can realize Edge molecular to sieve in 7 intake processes and keep inner tight to contact, to improve drying effect because of the effect of edge compressing structure 10; Can also realize producing dispersion because of the up-down vibration of edge holddown spring 3 in blowback process, to improve regeneration effect.Middle element sieves middle holddown spring 11 and exhaust structure 16 version of 14 two ends settings, also can realize above-mentioned same effect.
The position of secondary turbulent flow block 5 can according to required filtering material volume number adjust up and down, as shown in Figure 1, realize the change that filtering material removes mist of oil and impurity ability, to adapt to dissimilar vehicle and use occasion.One-level turbulent flow hole 2, secondary turbulent flow hole 6 and three grades of turbulent holes 11 are all expanding circular table apertures, the aperture of this structure type can make gas produce turbulent free jet phenomenon, realize gas to be dried dispersing after small holes to slow down with speed, to improve contact area and the time of contact of gas to be cleaned and desiccant material and filtering material; The one-level turbulent flow hole 2 offered, secondary turbulent flow hole 6 and three grades of turbulent holes 11 are all that circumferentially inner and outer rings is uniform, drying chamber is entered by different parts to realize gas to be dried, make more desiccant material participate in dry run simultaneously, improve the utilization rate of desiccant material; But the distance of alternating expression arrangement aperture can not be too near, to avoid Turbulent Mixing effect.
