Connecting structure of reboiler heat exchanger of rectifying tower

Abstract

The invention belongs to the technical field of rectifying towers, and particularly relates to a connecting structure of reboiler heat exchanger of rectifying tower, which comprises a rectifying tower, wherein the rectifying tower comprises a tower kettle and a tower body, the tower body is installed at the top of the tower kettle, and the tower kettle and the tower body are connected through a reboiler heat exchanger; a reboiler heat exchanger, which comprises a heat exchanger body, a lower sealing head and a connecting pipe, the heat exchanger body is installed at the bottom of an inner cavity of the tower body, the lower sealing head is arranged at the bottom of the heat exchanger body, the connecting pipe is arranged in the center of the heat exchanger body, and the bottom of the connecting pipe penetrates through the lower sealing head, the tower body and an upper sealing head of the tower kettle, and the bottom of the connecting pipe extends to the inner cavity of the tower kettle, and the top of the connecting pipe extends to the inner cavity of the tower body, so that the structure is reasonable, after the design is improved, the design calculation of equipment is simplified, the welding of the reboiler heat exchanger connecting plate and the barrel body is not adopted any more, the welding process is simple, purchasing and manufacturing are convenient to realize, and meanwhile, the design and production cost is also reduced.

Description

technical field [0001] The invention relates to the technical field of rectification towers, in particular to a connection structure for a reboiler heat exchanger of a rectification tower. Background technique [0002] In the equipment that adopts the cryogenic separation method, the rectification tower equipment is very important. The design technology of the rectification tower directly affects the performance and output of the whole process. As a part of the rectification, the reboiler heat exchanger also plays an important role. Key role. In order to meet the current technological requirements, the original rectification column reboiler heat exchanger structure is technically improved to make it more reasonable and convenient for design and manufacture. The general structure of the original rectification tower reboiler heat exchanger is that the heat exchanger is placed in a container and directly welded to the rectification tower cylinder. The design calculation needs ...

AI Technical Summary

Problems solved by technology

The general structure of the original rectification tower reboiler heat exchanger is that the heat exchanger is placed in a container and directly welded to the rectification tower cylinder. The design calculation needs to be calculated by the method of analysis and design. Because the analysis method is relatively seldom used, the design sometimes difficult

In addition, as the size of the tower body increases, the connecting plate of the reboiler heat exchanger will become thicker and thicker, making it difficult to purchase materials and increase the difficulty of welding
