Description

Technical Field

[0001] The utility model relates to the technical field of centralized condensation recovery, in particular to a reaction condensation recovery device for a normal pressure reactor. Background Art

[0002] The three normal pressure reactors can be fed with materials for reaction independently. Each reactor has an independent reflux condenser, which is connected to the atmosphere after passing through the condenser, i.e., the first-level condensation. The reflux condenser is connected to the circulating cooling water. During the reaction process, there will be a mixed gas of water vapor and carbon dioxide carrying part of the fennel oil. Most of the mixed gas will be condensed and refluxed into the reactor after passing through the first-level condenser, but it still needs to be further condensed and recovered.

[0003] For the substance to be recovered by internal condensation, that is, the mixed gas, when it flows in the pipeline, it is not conducive to synchronously conducting the heat and cooperating with the cooling mechanism to quickly cool it down. The cooling rate is low, which reduces the efficiency of its condensation recovery.

[0004] Therefore, we proposed a normal pressure reactor reaction condensation recovery device to solve the above-mentioned problems. Utility Model Content

The outer side of the driving gear is meshed with a driven gear, and the driven gear key is connected to the outer side of the left end of the cooling pipe, and the cooling pipe is rotatably connected to the mounting plate.

[0009] Preferably, the centralized drain pipe and the connecting pipe are both stainless steel pipes, and the centralized drain pipe and the connecting pipe are both φ89mm. This design can be used for centralized condensation recovery.

[0010] Preferably, the highest point of the external drain port is higher than the lowest point of the connecting pipe, and the length of the connecting pipe is 35m. This design can prevent the condensed oil and water from flowing out by raising the external drain port.

[0011] Preferably, the heat sink is evenly distributed on the outside of the centralized exhaust pipe, and an arc-shaped groove is opened at the rear end of the heat sink. The arc-shaped groove of the heat sink fits with the cooling pipe. This design can utilize the heat sink to conduct heat in the centralized exhaust pipe, concentrate the heat to the cooling pipe, and use the cooling pipe to perform rapid cooling and condensation.

[0012] Preferably, the ends of the water inlet pipe and the drain pipe extending into the cooling pipe are both side "T" shaped structures, and the cooling pipe, the water inlet pipe and the drain pipe all form a rotating structure. This design can ensure that the cold water flows smoothly in the cooling pipe while ensuring the smooth rotation of the cooling pipe.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) The atmospheric pressure reactor reaction condensation recovery device has a centralized emptying pipe that connects the emptying ports of the three reactors in series, and a connecting pipe connects them to the external emptying port outside the workshop. This section of the pipe not only plays the role of centralized emptying, but also plays the role of secondary condensation. By raising the external emptying port, the condensed oil and water can be prevented from flowing out, and the oil and water can be separated and collected in a centralized collection tank;

In addition, the driving gear and the driven gear are driven in meshing to control the rotation of the cooling pipe and exchange the contact surface of the cooling pipe and the heat sink, which can avoid damage caused by continuous single-sided heating of the cooling pipe, and can also increase the heat dissipation rate of the heat sink, further improving the condensation recovery efficiency.
