Abstract
The utility model discloses a be used for protecting cylinder closing device of adsorbent in adsorption tower, including adsorption tower body, cylinder, blind flange and clamp plate, adsorption tower body top is equipped with the cylinder, the cylinder includes air inlet and gas vent for pneumatic means, the cylinder bottom is equipped with a cylinder axle, the tip and the clamp plate fixed connection of cylinder axle, the clamp plate lies in and adsorbs tata mouth inner chamber, the clamp plate below is equipped with the coconut palm pad, the cylinder off -axial still overlaps and is equipped with the blind flange, blind flange and cylinder bottom fixed connection, the bolt fastening is adsorbing the tata mouth for the blind flange. Set up cylinder closing device on the blind flange, just can drive the clamp plate through the cylinder bearing with the clamp plate and compress tightly the adsorbent in the adsorption tower, avoid the adsorbent to produce the clearance in the adsorption tower, prevent that the adsorbent is because of the broken pulverization of collision each other to reach and keep the adsorbent to compress tightly the mesh that the dense state was used.
Description
Technical field
The utility model relates to a kind of air separation plant, especially a kind of for the air-cylinder compressing device for the protection of adsorbent in the adsorption tower of PSA nitrogen, oxygen generating plant.
Background technology
Adsorbent is filled with in nitrogen oxygen adsorption tower processed, on the one hand, adsorbent collides mutually because of the effect being subject to gas shock, causes adsorbent fragmentation efflorescence even gradually, thus make that the volume of adsorbent reduces gradually, service life shortens, gap will be produced strengthen gradually in adsorption tower; On the other hand, once there be gap in adsorption tower, adsorbent more can aggravate mutual collision, thus absorbent atomizing phenomenon is increased the weight of more, reduction of service life; If instant mode of shutting down supplementary adsorbent eliminates the gap of adsorbent, will affect user and normally produce, or, increase a stand-by equipment, the input of large equipment must be added, increase financial burden to user.
Visible, how to eliminate the gap that adsorbent is present in adsorption tower inside, making adsorbent keep normal and use, is the problem that air separation unit technique field must solve.
Utility model content
Problem to be solved in the utility model improves the problem of the easy efflorescence of adsorbent in existing adsorption tower in background technology.
The purpose of this utility model is to provide the air-cylinder compressing device for the protection of adsorbent in a kind of adsorption tower, comprise adsorption tower body, cylinder, blind flange and pressing plate, described adsorption tower bodies top is provided with cylinder, described cylinder is that pneumatic means comprises air inlet and exhaust outlet, described cylinder bottom is provided with a cylinder axis, the end of described cylinder axis is fixedly connected with pressing plate, described pressing plate is positioned at adsorption tower tower mouth inner chamber, coconut palm pad is provided with below described pressing plate, described cylinder axis is also arranged with blind flange outward, described blind flange is fixedly connected with cylinder bottom, described blind flange is fixed by bolts to adsorption tower tower mouth.
Sealing ring is provided with in described blind flange.
Energy-saving nonloss air regenerative dryer of the present utility model is provided with air-cylinder compressing device on the blind flange of adsorption tower, just can with pressing plate by the adsorbent in bearing cylinder band dynamic pressure plate compression adsorption tower, avoiding adsorbent in adsorption tower, produce gap, preventing adsorbent because mutually colliding and breaking and Dusting, thus reach the object keeping adsorbent to press closely state use; Pressing plate is compressed adsorbent degree clearly for being no more than the normal ability to bear of adsorbent, pressing plate just can be avoided adsorbent pressure tightly still not to be there will be to gap or pressure excessive and crush adsorbent; Distance bearing plate being extended minimum adsorbent height is clearly the maximum clamping stroke of air-cylinder compressing device, just can supplement adsorbent in time, prevents adsorbent from affecting equipment operation because quantity reduces sinking.This technical scheme, structure is simple, effect is obvious, also easily implements, and is to eliminate the ideal hold down gag of adsorption tower internal clearance.
Accompanying drawing explanation
Fig. 1 is the schematic diagram for the protection of the air-cylinder compressing device of adsorbent in a kind of adsorption tower of the present utility model.
1, adsorption tower body; 2, cylinder; 21, air inlet; 22, exhaust outlet; 23, cylinder axis; 3, blind flange; 4, pressing plate; 41, coconut palm pad.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described, as shown in Figure 1, for the protection of the air-cylinder compressing device of adsorbent in the adsorption tower of the present embodiment, comprise adsorption tower body 1, cylinder 2, blind flange 3 and pressing plate 4, adsorption tower body 1 top is provided with cylinder 2, cylinder 2 comprises air inlet 21 and exhaust outlet 22 for pneumatic means, a cylinder axis 23 is provided with bottom cylinder 2, the end of cylinder axis 23 is fixedly connected with pressing plate 4, pressing plate 4 is positioned at adsorption tower tower mouth inner chamber, coconut palm pad 41 is provided with below pressing plate 4, cushioning effect can be played to air-flow, prevent adsorbent because being subject to the percussion of air-flow and impaired, cylinder axis 23 is outer is also arranged with blind flange 3, blind flange 3 is fixedly connected with bottom cylinder 2, blind flange 3 is fixed by bolts to adsorption tower tower mouth.Blind flange is set and can prevents Leakage Gas.
In this enforcement, when hold down gag does compression operation, the air inlet of cylinder passes into air-flow, and the pressure in intensifying cylinder makes cylinder axis do downward motion, and cylinder axis band dynamic pressure plate presses down and compressed by the adsorbent in adsorption tower.Coconut palm pad is set under pressing plate simultaneously, prevents pressing plate from damaging adsorbent.Pressing plate compress adsorbent degree clearly for being no more than the normal ability to bear of adsorbent, pressing plate just can be avoided adsorbent pressure tightly still not to be there will be to gap or pressure excessive and crush adsorbent; When doing feeding operation, be communicated with the exhaust outlet of cylinder, make cylinder step-down, cylinder axis band dynamic pressure plate moves, adsorbent is fed in raw material from adsorption tower charge door.Distance bearing plate being extended minimum adsorbent height is clearly the maximum clamping stroke of air-cylinder compressing device, just can supplement adsorbent in time, prevents adsorbent from affecting equipment operation because quantity reduces sinking.
In this enforcement, in blind flange 3, be provided with sealing ring.Sealing ring is set, prevents compressed air from revealing further, improve the seal of adsorption tower.Simple for the protection of the air-cylinder compressing device structure of adsorbent in the adsorption tower of the present embodiment, easily implement, solve the problem of the easy efflorescence of adsorbent, substantially prolongs the service life of adsorbent.
The utility model is not limited to above embodiment and conversion.
