Description

Technical Field

[0001] This utility model relates to the field of tower reactor technology, specifically an energy-saving tower reactor. Background Technology

[0002] In chemical production, it is often necessary to achieve mixing and reactions between multiple phases such as gas and liquid, and liquid and liquid. For example, in the fields of petrochemicals and fine chemicals, many chemical reactions involve substances in different phases, such as the reaction between gas and liquid, and the extraction between liquids. A tower reactor is a vertical cylindrical device with a height much greater than its diameter, and its core structural design revolves around the efficient contact between gas and liquid (or liquid-liquid, gas-solid-liquid) two phases.

[0003] Existing patent document CN221310679U provides a tower reactor including a tower body and a reaction liquid-gas mixing mechanism. A liquid inlet is installed at the top left side of the tower body, and an air inlet is installed at the bottom right side of the tower body. A liquid stagnation plate is fixedly connected to the inside of the tower body, and a liquid stagnation ring is fixedly connected to the top of the liquid stagnation plate. An air inlet is opened at the top of the liquid stagnation plate, and a convex plate located outside the air inlet is fixedly connected to the top of the liquid stagnation plate. A gas mixing ring is fixedly connected to the surface of the convex plate. By setting up the reaction liquid-gas mixing mechanism, after the liquid enters the tower body through the liquid inlet, the liquid is retained, which promotes the contact and mixing of the gas entering through the air inlet with the liquid. This increases the contact reaction time and contact mixing effect between the liquid and the gas, avoids the situation where the liquid and gas cannot fully contact and react during the reaction process, and thus improves the mixing reaction effect of the tower body.

[0004] However, in the operation of existing tower reactors, due to the lack of efficient heat exchange systems or heat recovery devices, the high-grade heat energy that could have been used to preheat the feed is directly discharged or cooled, resulting in energy waste. Because it is difficult to recover and utilize the energy, the waste heat of the tail gas at the top of the tower or the product at the bottom of the tower cannot be used to heat the feed, which requires additional heating energy consumption, resulting in poor energy saving effect of tower reactors. To address this issue, we propose an energy-saving tower reactor. Utility Model Content

[0024] Furthermore, a second return pipe 15 is integrally formed at one end of the heat exchange tube 16. The second return pipe 15 is threadedly connected to the first return pipe 9, and the heat exchange medium can flow back into the heat exchange box 10 through the second return pipe 15 and the first return pipe 9.

[0025] Furthermore, a liquid inlet pipe 11 and a liquid outlet pipe 12 are threadedly connected to one side of the heat exchange box 10. Both the liquid inlet pipe 11 and the liquid outlet pipe 12 are hollow structures. The heat exchange medium can be added through the liquid inlet pipe 11 and discharged through the liquid outlet pipe 12.

[0026] Furthermore, the heat exchange tube 16 has a spiral structure and is located on the inner wall of the tower body 1. The spiral structure of the heat exchange tube 16 allows for a larger contact area with the heat source for heat exchange.

[0027] Furthermore, a spray ring 19 is fixedly connected to the other end of the conveying pipe 3. A spray head 20 is threadedly connected to the bottom of the spray ring 19.

When using the tower reactor, gas enters the tower body 1 through the inlet pipe 5. The gas moves upward along the partition 17 and the filling layer 18 and is discharged from the exhaust pipe 6. At this time, the liquid pump 4 draws liquid and delivers it to the spray ring 19 through the delivery pipe 3, and sprays it into the tower body 1 through the spray head 20.
