How to optimize the structure of equipment support in the cold box of air separation plant

The tower support of the air separation unit is mainly used to support the tower body in the cold box, and the common tower form is mainly composed of ring plate, rib plate, riser and connecting straight pipe.

Through the finite element analysis of the traditional solid model, and through the correct loading and boundary conditions, considering the low height of the tower support, and without considering the impact of wind load, seismic load, ice and snow load, the load mainly includes the dead weight of the support and the weight of the tower and its accessories. Therefore, only symmetric constraints are added to the symmetric plane to constrain its displacement degrees of freedom along the normal direction of the symmetric plane, and full constraints are added to the bottom to constrain the degrees of freedom in three directions. The specific optimization scheme is as follows: considering that the rib plate hardly plays a supporting role, the rib plates between the two annular plates are all canceled; Cancel one straight pipe connecting the risers and replace it with two inclined pipes. Support the annular plate diagonally to reduce the included angle between it and the two risers. Through strength check, the bearing capacity of the optimized structure is 3 times higher than that of the original, and the structure is simpler, the processing is more convenient, and the production cost is reduced.

Through the use of finite element analysis software, DEAR Air Separation Plant carries out model analysis and optimization for the commonly used empirical tower of air separation equipment, so as to improve the bearing capacity of the support, reduce the processing difficulty and save the material cost.

Small air separation unit is the unit that separates air into oxygen and other gases by first compressing and cooling the air into a liquid state and then using the characteristic that oxygen has a different boiling point to other gases in the air to obtain oxygen and liquid oxygen by evaporation and separation, as well as other rare gases as required.Liquid oxygen is produced using the cryogenic separation of air. The basic principle is to u...

The pressure relief of molecular sieve in the purification system is generally rapid in the early stage, not complete and running overtime in the later stage. The pressure relief degree is adjusted by the manual stop valve in front of the pressure relief valve. Through practical adjustment, no matter how it is adjusted, the pressure relief in front is fast, or the pressure can not be exhausted. It is suggested that the valve positioner should be added to the automatic pressure relief valve, and the pressure linear adjustment should be programmed, so that the impact on molecular sieve will be much smaller.
