Description
Technical Field
The invention relates to the technical field of adsorption towers, in particular to an adsorption tower device.
Background
The adsorption tower is filled with molecular sieve packing such as molecular sieve, so that certain components in gas or liquid entering the tower are adsorbed by the porous structure of the adsorbent, thereby realizing the component separation.
In the prior art, in the working process of an adsorption tower, molecular sieve packing materials such as molecular sieves are scraped when receiving air inlet pressure from the lower part, and the mutual friction generated by scraping of the molecular sieves causes the pulverization problem;
in order to prevent the friction loss caused by the pressure difference of the molecular sieve filler such as the molecular sieve in the adsorption tower, a pressing device (porcelain beads, a cylinder, a spring and the like) is added at the upper part of the adsorption tower, so that the molecular sieve filler such as the molecular sieve filler cannot move when receiving the air inlet pressure from the lower part, and the pulverization problem caused by the mutual friction generated by the scraping of the molecular sieves is prevented.
However, the above-mentioned compressing method still has certain problems:
1) when the porcelain beads are adopted for compaction, the filling is too much or too little or not uniform under the influence of the technical level of designers and constructors. The excessive ceramic beads increase the bearing of the molecular sieve below and occupy the space of the adsorption tower to form the inner space of the ineffective adsorption tower; and too few ceramic beads can not meet the pressing requirement, and rolling wear still occurs.
2) When the air cylinder is adopted for compaction, one or more air cylinders are arranged above the adsorption tower, the air source of the air cylinder is the same as that of the adsorption tower, and the sectional area of the air cylinder is far smaller than that of the adsorption tower, so that the air cylinder cannot be balanced with the air below the adsorption tower, friction caused by the up-and-down movement of the molecular sieve still occurs, and the molecular sieve pulverization is further caused.
3) When the spring is adopted for pressing, the operation is difficult when the upper cover of the adsorption tower is installed, and the molecular sieve is gradually compacted and sunk along with the use of the molecular sieve, so that the pressing force of the spring is reduced, meanwhile, in the service cycle of not less than 10 years, the mechanical strength of the spring is reduced, the spring cannot be pressed, and finally, the pulverization problem still occurs.
In conclusion, the compressing technology cannot meet the requirement of the whole life cycle of the adsorption tower, and the failure of the compressing device can cause the pulverization failure of the molecular sieve, so that a compressing structure of the adsorption tower with long service life and high reliability is urgently needed.
