Technical Field

[0001] The utility model relates to the technical field of reactor cooling, in particular to a rapid cooling device for a catalyst reactor. Background Art

[0002] A reactor is broadly understood as a container for physical or chemical reactions. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process are achieved. During the use of the reactor, a rapid cooling device is often required.

[0003] The existing reactor cooling device usually places a cooling pipe in the outer wall interlayer of the reactor and uses the cooling pipe to cool the inside of the reactor. However, since the reactor is usually configured as a cylinder, the heat conduction efficiency on the side of the reactor away from the inner wall is insufficient. Although the internal material will move, the overall contact time with the inner wall of the reactor is short, resulting in a certain room for improvement in cooling efficiency. In view of this, we propose a rapid cooling device for a catalyst reactor. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art and to provide a rapid cooling device for a catalyst reactor, which can solve the problem that the internal material has a short contact time with the inner wall, resulting in low cooling efficiency of some materials.

[0006] Preferably, a spiral plate is fixedly connected to the inner wall of the annular cavity, the interior of the annular cavity is communicated with the interior of the storage ring, and a heat dissipation hole is opened on the upper surface of the storage ring, and the lower side of the heat dissipation hole extends into the interior of the storage ring.

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

[0014] (1) The rapid cooling device of the catalyst reactor, when cooling the reactor, uses a first water pump to transport the cooling water in the storage ring through a delivery pipe to the interior of the spiral cooling pipe. Since the spiral cooling pipe is placed inside the reactor and is generally in a threaded shape, the contact area with the outside is increased, thereby improving the overall cooling efficiency. The used cooling water is transported back to the interior of the storage ring through the lower end of the spiral cooling pipe. Through the above structure, when cooling the interior of the reactor, the contact area with the internal material can be increased through the spiral cooling pipe placed inside, and the interval of the material circulation contacting the inner wall is also compensated, thereby effectively improving the overall cooling efficiency.

[0015] (2) The rapid cooling device of the catalyst reactor conducts heat to the heat sink through the heat conduction plate, and increases the contact area with the outside air through the folds on the heat sink, thereby improving the heat dissipation of the cooling water. When stirring is required, the driving motor can be used in conjunction with the driving shaft to drive the stirring blade to rotate. Through the above structure, the cooling water can be recycled back to the interior of the storage ring and can be quickly cooled through the heat conduction plate, the heat sink and the heat dissipation holes, thereby avoiding the high cooling water temperature causing a decrease in the subsequent cooling rate of the reactor.

The upper end of the spiral cooling tube 5 is fixedly connected, and the lower end of the spiral cooling tube 5 passes through the interior of the storage ring 2. When the reactor 1 is cooled, the cooling water in the storage ring 2 is transported to the interior of the spiral cooling tube 5 through the transport pipe 8 by the first water pump 7. Since the spiral cooling tube 5 is placed inside the reactor 1 and is in a threaded shape as a whole, the contact area with the outside is increased, thereby improving the overall cooling efficiency. The used cooling water is transported back to the interior of the storage ring 2 through the lower end of the spiral cooling tube 5. Through the above structure, when the interior of the reactor 1 is cooled, the contact area with the internal material can be increased through the spiral cooling tube 5 placed inside, and the interval of the material circulation contacting the inner wall is also compensated, thereby effectively improving the overall cooling efficiency.

At the same time, after the cooling water enters the interior of the storage ring 2, it can not only use the heat dissipation holes 10 to interact with the outside air to dissipate the cooling water, but also conduct the heat to the heat dissipation plate 18 through the heat conduction plate 17, and increase the contact area with the outside air through the folds on the heat dissipation plate 18 to improve the heat dissipation of the cooling water, and when stirring is required, the driving motor 13 can be used to cooperate with the driving shaft 14 to drive the stirring blade 15 to rotate.

[0025] Working principle: When cooling the reactor 1, the cooling water in the storage ring 2 is transported to the inside of the spiral cooling tube 5 through the first water pump 7 through the delivery pipe 8. Since the spiral cooling tube 5 is placed inside the reactor 1 and is in a threaded shape as a whole, the contact area with the outside is increased, thereby improving the overall cooling efficiency. The used cooling water is transported back to the inside of the storage ring 2 through the lower end of the spiral cooling tube 5. The cooling water can also be transported to the inside of the annular cavity 4 through the second delivery pipe 12 with the help of the second water pump 11, and the cooling water is made to descend in a spiral shape with the help of the spiral plate 9, so that the cooling water contacts the inner wall again and absorbs the heat of the inner wall. At the same time, after the cooling water enters the storage ring 2, it can not only use the heat dissipation holes 10 to interact with the outside air to dissipate the heat of the cooling water, but also conduct the heat to the heat dissipation plate 18 through the heat conduction plate 17, and the contact area with the outside air is increased through the folds on the heat dissipation plate 18, thereby improving the heat dissipation of the cooling water. When stirring is required, the driving motor 13 can be used in conjunction with the driving shaft 14 to drive the stirring blade 15 to rotate.
