The utility model discloses a tube sheet to the decompression refining tower reboiler among the prior art improves, reforms original solid tube sheet into the backing plate that the net that is formed by the carbon steel supported and the stainless steel forms, and for original structure, the cost of material has not only been practiced thrift to hollow grid structure, has still strengthened the pressure-bearing of tube sheet.
Description
Technical Field
The utility model relates to a chemical industry equipment field, concretely relates to pressure reduction refining tower reboiling ware tube plate structure.
Background
In petrochemical production plants, rectification is a widely used chemical separation unit operation and is one of the most efficient methods for separating homogeneous liquid mixtures. Meanwhile, the rectification is a chemical unit operation with high energy consumption and large equipment investment. Therefore, the energy saving and equipment optimization of the rectification process have very important significance in the energy saving of the petrochemical industry. In order to reduce the energy consumption of the rectification operation and to utilize a heat source with lower grade and price, the stripping section of some rectification towers is provided with an intermediate reboiler. The reboiler of the decompression rectification tower has less tower plates, small pressure drop, high vacuum degree and large tower diameter. In order to increase the extraction depth as much as possible and avoid decomposition, the vacuum section of the vaporization section is required to be increased as much as possible by the reboiler of the vacuum distillation column under an economically reasonable condition. Therefore, it is desirable to enhance the pressure bearing of the tray bottoms.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a strengthen the reboiling tubular plate structure of decompression refining tower of bottom pressure-bearing.
The technical scheme of the utility model is that: the utility model provides a decompression refining tower reboiler tube sheet structure, is including being used for with reboiler barrel fixed connection's tube sheet body, setting at this internal supporting part of tube sheet, the supporting part includes the net skeleton that forms through metal sheet vertically and horizontally staggered connection, sets up the backing plate in net skeleton top, the external diameter of backing plate and the internal diameter phase-match of reboiler barrel, the backing plate passes through welded fastening connection net skeleton and tube sheet body.
Further technical scheme, the inner circle of tube sheet body is equipped with downwardly extending's step, forms the cell body that is used for holding the reboiler barrel between backing plate and the step, the width of cell body and the wall thickness phase-match of boiling ware barrel.
According to the further technical scheme, the metal plate is made of carbon steel, and the backing plate is made of stainless steel.
The utility model has the advantages that:
the utility model discloses a tube sheet to the decompression refining tower reboiler among the prior art improves, reforms original solid tube sheet into the backing plate that the net that is formed by the carbon steel supported and the stainless steel forms, and for original structure, the cost of material has not only been practiced thrift to hollow grid structure, has still strengthened the pressure-bearing of tube sheet.
