A reboiler for high gravity rectification

Abstract

The invention relates to a reboiler for supergravity rectification, and belongs to the technical field of a chemical heating device. The device comprises the reboiler and a rectifying tower, wherein a material gas phase outlet in the reboiler is connected with one side of the rectifying tower; a natural return flow inlet in the reboiler is connected with the bottom part of the rectifying tower; a reboiler shell in the reboiler is connected with an end cover through a flange connector, a heat exchange component comprises an outlet collecting pipe, an inlet collecting pipe and a plurality of snakelike heat exchange pipes, rows of even number of snakelike heat exchange pipes are arranged on the outlet collecting pipe and the inlet collecting pipe from up to down and are respectively communicated with the outlet collecting pipe and the inlet collecting pipe, the snakelike heat exchange pipes are mounted at the inner part of the reboiler shell through heat exchange pipe support frames, the outlet collecting pipe and the inlet collecting pipe are respectively in airtight connection with a heating steam outflow pipe and a heating steam inflow pipe outlet of the end cover. The reboiler for supergravity rectification can improve reboiler heat exchange efficiency and fully use the heat energy and is easy in maintenance and replacement of a heat exchanger.

Description

technical field [0001] The invention relates to a reboiler for high-gravity rectification, belonging to the technical field of chemical heating devices. Background technique [0002] High-gravity rectification technology is a new type of separation technology, which is carried out on the basis of a high-gravity rectification tower. A huge interphase contact area is produced, which increases the gas-liquid contact area by several orders of magnitude, thereby achieving the purpose of greatly improving the gas-liquid mass transfer efficiency. Compared with the traditional distillation method, this method has the characteristics of finer, safer and more efficient, has remarkable energy-saving effect, and is more adaptable to the requirements of the environment and enterprises. [0003] The reboiler is a special heat exchanger capable of exchanging heat while having a space for vaporization. In industrial production, the main function of heat exchange equipment is to transfer h...

AI Technical Summary

Problems solved by technology

[0005] The reboiler mainly has the following two major disadvantages: first, the heat transfer area and heat transfer efficiency of the reboiler are low, and the heat energy cannot be fully utilized; Seriously restrict the normal operation of production

[0006] The utility model patent No. CN104096368A discloses a reboiler, which inserts one end of the heat exchanger tube into the reboiler shell and connects the other end to the end through the reboiler shell. The purpose of easy maintenance and replacement of the heat exchanger is achieved, but due to the small heat transfer area of ​​the heat exchange tube, there are disadvantages of low heat transfer efficiency and inability to fully utilize heat energy

[0007] The invention patent with the patent number of CN104059687A discloses a reboiler, which has guide chambers at both ends of the reboiler and a heating chamber in the middle, and adopts a multi-layer heat exchange method to improve the heat transfer efficiency of the reboiler. purpose, but because the heat exchange tube is completely fixed in the heating chamber, it is difficult to maintain and replace the heat exchange tube.
