Description

Technical Field

[0001] The utility model specifically relates to a waste heat recovery device for a regeneration tower. Background Art

[0002] The regeneration tower is a device used to analyze the absorbed or adsorbed substances to restore the performance of the solvent or adsorbent. It is commonly used in gas treatment, chemical and environmental protection processes. When the regeneration tower is in use, acid gas will carry heat out of the exhaust at the top of the tower. In order to reuse this heat, it is necessary to absorb the heat through a heat-conducting liquid, and then transfer the heat to the outside or to the bottom of the tower to heat the amine liquid at the bottom of the regeneration tower, reducing the need for external heat.

[0003] However, when transferring heat to recycle the waste heat of acid gas, the heat exchange pipes need to be arranged with liquid inlet and outlet heat exchange pipes to realize the circulation of heat transfer liquid. The inlet and outlet pipes need to be arranged, which is troublesome. In addition, multiple heat exchange pipes cannot be quickly assembled according to the height of the exhaust gas. It is also troublesome to maintain the inlet and outlet pipes separately in the later stage. For this reason, we propose a waste heat recovery device for the regeneration tower.

[0028] In this embodiment, preferably, the heat exchange tube 3 is vortex-shaped, so as to improve the contact effect with the flue gas and improve the recovery rate of the waste heat.

[0029] In this embodiment, preferably, the connecting mechanism 6 includes a connecting box 61, a first liquid discharge pipe 62 and a liquid inlet pipe 63. The connecting box 61 is fixed to the other end of the heat exchange tube 3, and the lower surface of the connecting box 61 is provided with a liquid inlet pipe 63 connected to the interior of the first heat exchange channel. The first liquid discharge pipe 62 is fixed on the connecting box 61, and the first liquid discharge pipe 62 is connected to the interior of the second heat exchange channel, so as to facilitate the connection of the two heat exchange tubes 3 and assemble different numbers of heat exchange tubes 3 according to the length of the exhaust port 2.

[0030] In this embodiment, preferably, the connecting mechanism 6 also includes a second drain pipe 64, which is arranged on the front surface of the connecting box 61, and the second drain pipe 64 is connected to the inside of the first drain pipe 62 to facilitate the discharge of the heat-conducting liquid in different directions.
