Anti-coking fine steaming reboiling device

Abstract

The invention relates to the technical field of distillation equipment, and discloses an anti-coking fine steaming reboiling device which comprises a square shell and a heat exchange pipe, wherein the top of the shell is fixedly connected with a first feeding pipe, the bottom of the shell is fixedly connected with a discharging pipe, one side of the shell is fixedly connected with a second feeding pipe, and the top of the shell is fixedly connected with an air outlet pipe; cavities are symmetrically formed in the shell, a heat exchange cavity is fixedly formed between the two cavities, a partition plate is fixedly connected between the cavities and the heat exchange cavity, the multiple heat exchange pipes are laid in the heat exchange cavity, baffles are fixedly connected to the cavities, the heat exchange pipes penetrate through the partition plate and communicate with the cavities, connecting ropes are arranged in the heat exchange pipes, two ends of the connecting rope are fixedly connected with winding devices, and the winding devices are fixedly arranged on the baffle plate. According to the device, the inner wall of the heat exchange pipe can be cleaned conveniently, and the heat exchange efficiency is high.

Description

technical field [0001] The invention relates to the technical field of distillation equipment, in particular to an anti-coking fine distillation reboiler. Background technique [0002] Reboiler (also known as reboiler), as its name implies, is to vaporize liquid again. Its structure is similar to that of condenser, but condenser is used to cool down, while reboiler is used to heat up and vaporize. Reboiler is mostly related to fractionation The reboiler is a special heat exchanger capable of exchanging heat and has a vaporization space. The material level in the reboiler is at the same height as the liquid level of the fractionation tower, and the liquid phase is supplied from the bottom line of the tower to the In the reboiler, usually 25-30% of the liquid phase is vaporized in the reboiler, and the vaporized two-phase flow is sent back to the fractionation column, and the gas phase components in the return column pass upward through the tray, while the liquid phase The ph...

Problems solved by technology

[0005] First, multiple heat exchange tubes are usually used inside the existing reboiler to exchange heat through the heat exchange tubes, but the position of the heat exchange tubes remains fixed, and the tubes cannot rotate and move during heat exchange, resulting in The heat exchange of materials inside the hot pipe is uneven and the efficiency is low;

[0006] Second, during the actual use of the heat exchange tube, the heat exchange tube needs to be cleaned regularly. When the inside of the heat exchange tube needs to be cleaned, the device needs to be disassembled, and then the heat exchange tube is removed for cleaning one by one. The cleaning is completed After that, the heat exchange tube needs to be reinstalled, the cleaning operation is complicated and the efficiency is low
