In industrial production, especially in the chemical, pharmaceutical, fertilizer, and refining industries, reaction vessels are used in large quantities as a pressure-bearing equipment due to process needs. In order to reduce the temperature of the working medium in the reaction vessel, the common practice in the prior art is to set a jacket cooling on the wall of the reaction vessel. However, we found in our daily work that the cooling effect of the jacket cooling after the equipment is running often does not meet the working condition requirements. What should we do? If the cost of remanufacturing a device is high and the manufacturing cycle is long, we are thinking about whether we can develop a cooling coil assembly, and then send them into the existing equipment from the manhole of the equipment, and then assemble them in the existing equipment, so as to improve the cooling effect of the working medium without remanufacturing the equipment.

[Specific implementation method]

[0022] The reaction vessel with a cooling coil assembly according to the present invention is further described in detail below through specific embodiments.

[0023] Ginseng Figures 1 to 6 As shown, a reaction vessel with a cooling coil assembly comprises: a reaction vessel 1 and a cooling coil assembly arranged in the reaction vessel 1. In this embodiment, the cooling medium in the cooling coil assembly is liquid ammonia. A manhole is provided on the reaction vessel, and the cooling coil assembly comprises: a cooling medium inlet pipe 2, a cooling medium descending pipe 3, a lower ring pipe 4, a plurality of groups of cooling medium ascending pipe assemblies 5, an upper ring pipe 6 and a cooling medium outlet pipe 7. In this embodiment, the diameter of the lower ring pipe 4 is greater than the diameter of the upper ring pipe 6. The upper ring pipe 6 is arranged above the agitator 8. Because the diameter of the lower ring pipe 4 is larger, it is arranged on the periphery of the agitator 8, and both avoid the agitator 8. A first pipe opening 10 matched with the cooling medium inlet pipe 2 and a second pipe opening 11 matched with the cooling medium outlet pipe 7 are provided above the cylinder of the reaction vessel 1. Both the upper ring pipe 6 and the lower ring pipe 4 are segmented welded structures, and the segmented structure can facilitate their entry and exit of the manhole. The cooling medium inlet pipe 2 is connected to the cooling medium descending pipe 3 through a first connecting pipe 20. In this embodiment, the cooling medium inlet pipe 2 and the first connecting pipe 20 are arranged at an angle of 135°. The bottom of the cooling medium descending pipe 3 is connected to the lower ring pipe 4, the bottoms of the several groups of cooling medium ascending pipe assemblies 5 are respectively connected to the lower ring pipe 4, and the tops of the several groups of cooling medium ascending pipe assemblies 5 are respectively connected to the upper ring pipe 6 through a second connecting pipe 50. In this embodiment, the second connecting pipe 50 is arranged at an angle of 135° to the upper ring pipe 6. The upper ring pipe 6 is connected to the cooling medium outlet pipe 7 through a third connecting pipe 60. In this embodiment, the third connecting pipe 60 is arranged in an S shape, so as to increase the heat exchange area and improve the cooling effect.

[0024] A jacket 30 is provided on the outside of the cooling medium descending pipe 3. The jacket 30 has a heat insulation effect to prevent the liquid ammonia from being vaporized in advance as soon as it enters the cooling medium descending pipe 3. Because our design requires the liquid ammonia to reach the lower ring pipe 4 before being vaporized, if the liquid ammonia is vaporized in advance as soon as it enters the cooling medium descending pipe 3, then the vaporized liquid ammonia is easy to run out from the cooling medium inlet pipe 2, thereby affecting the cooling effect. The jacket 30 is connected to the inner wall of the cylinder of the reaction vessel 1 through a plurality of groups of first connecting components 31. In this embodiment, the first connecting component 31 includes a first pad 310 welded to the inner wall of the cylinder of the reaction vessel 1 and a first connecting plate 311 welded between the first pad 310 and the jacket 30. Each group of cooling medium ascending pipe components 5 includes: an upper connecting pipe 51, a lower connecting pipe 52, an upper transverse pipe 53, a lower transverse pipe 54, and three vertical pipes 55 arranged between the upper transverse pipe 53 and the lower transverse pipe 54. The upper connecting pipe 51 is connected to the second connecting pipe 50, and the lower connecting pipe 52 is connected to the lower ring pipe 4. Each group of cooling medium ascending pipe assembly 5 is connected to the inner wall of the cylinder of the reaction vessel 1 through a plurality of second connecting assemblies 56. In this embodiment, the second connecting assembly 56 includes a sleeve 560 sleeved on the vertical pipe 55, a connecting rib plate 561 welded between each two adjacent sleeves 560, a second pad 562 welded to the inner wall of the cylinder of the reaction vessel 1, and a second connecting plate 563 welded between the connecting rib plate 561 and the second pad 562. A plurality of support members 9 welded to the inner wall of the reaction vessel 1 are provided below the lower ring tube 4. A lower ring plate 90 is welded to the top of the support member 9. The lower ring tube 4 is mounted on the lower ring plate 90 through a plurality of fixing members 40. In this embodiment, the support member 9 is an angle steel, and the fixing member 40 is a U-shaped bolt and nut.

[0025] The working principle of the cooling coil assembly in the present invention is as follows: liquid ammonia enters from the cooling medium inlet pipe 2, then passes through the first connecting pipe 20 to reach the cooling medium descending pipe 3, then the liquid ammonia continues to descend to the lower ring pipe 4 to exchange heat with the working medium in the reaction container 1 and vaporize, the vaporized liquid ammonia goes upward through several groups of cooling medium ascending pipe assemblies 5, and reaches the upper ring pipe 6 through the second connecting pipe 50, then passes through the third connecting pipe 60 to reach the cooling medium outlet pipe 7 and finally exits from the cooling medium outlet pipe 7.

[0026] In summary, the present invention adds a cooling coil assembly on the basis of the existing reaction vessel structure. The cooling coil assembly is composed of a plurality of connecting pipes, and the upper ring pipe and the lower ring pipe are both segmented welded structures. Therefore, when the cooling coil assembly is subsequently installed, each connecting pipe can be transported into the reaction vessel from the manhole of the reaction vessel respectively, without causing any damage to the original reaction vessel structure. In addition, the reason why the cooling coil assembly in the present invention adopts this structural arrangement is that an agitator is arranged in the center of the reaction vessel, so the arrangement of the cooling coil needs to avoid the agitator.

[0027] The above-mentioned embodiments are only illustrative of the principles and effects of the invention, as well as some embodiments of its application, and are not intended to limit the invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the invention, and all of these belong to the protection scope of the invention.
