[0002] Jacketed containers are widely used in the chemical industry to heat or cool the interior of the equipment. In order to ensure uniform heat transfer and rationally plan the flow of the heat exchange medium, a guide plate is often set between the jacket and the inner cylinder so that the heat exchange medium can flow through each area according to a certain pattern to improve the heat transfer efficiency.
[0003] See also Figure 1A , Figure 1B In the jacketed container known to the applicant, the jacketed container comprises an inner cylinder 11, a jacket 12 and a guide plate 13, and the guide plate 13 is spirally arranged between the inner cylinder 11 and the jacket 12. Figure 2 The heat exchange medium can move in a spiral in the track formed by the guide plate 13, and the black arrow indicates the flow direction of the heat exchange medium.
[0004] The guide plate 13 with a spiral structure is difficult to manufacture. Generally speaking, the guide plate 13 can serve as a reinforcing ring of the inner tube 11, increase the strength of the inner tube 11, and improve the allowable external pressure of the inner tube 11, so that the design thickness of the inner tube 11 can be reduced, saving costs. Figure 1A , Figure 1B , Figure 2 In the illustrated solution, the guide plate 13 is a spiral structure. On any cross section of the inner tube 11, the circular shape of the guide plate 13 is incomplete. The conventional reinforcement ring calculation formula cannot be applied to the guide plate 13. The analysis and calculation is time-consuming and laborious, and the reduction value of the inner tube thickness cannot be easily obtained. Summary of the invention

[0006] The jacketed container with guide plates comprises an inner tube, a jacket and a plurality of annular guide plates, wherein the guide plates are arranged between the inner tube and the jacket, and liquid can flow in a liquid channel formed by the outer surface of the inner tube, the inner surface of the jacket and the guide plates.
[0007] The guide plate comprises a first guide plate and a second guide plate which are arranged alternately and parallel to each other, the first guide plate is provided with an outer notch, the second guide plate is provided with an inner notch, and the liquid can flow across layers through the outer notch and the inner notch.
[0008] In at least one embodiment, the structure radially inside the outer notch of the first guide plate is a complete circular ring structure, and the structure radially outside the inner notch of the second guide plate is a complete circular ring structure.
[0009] In at least one embodiment, one of the first guide plates has and is only provided with one of the outer notches, and one of the second guide plates has and is only provided with one of the inner notches.
[0010] In at least one embodiment, on a plane where the guide plate is located, an orthographic projection of the outer notch and an orthographic projection of the inner notch are separated by an angle a in the circumferential direction of the guide plate, satisfying 90°≤a≤180°.

[0030] The exemplary embodiments of the present application are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the present application, and are not intended to exhaust all possible methods of the present application, nor to limit the scope of the present application.
[0031] The embodiment of the present application provides a jacketed container with a guide plate (hereinafter sometimes referred to as a "jacketed container"). Figure 3 , Figure 4 and Figure 5The jacketed container provided in the embodiment of the present application includes an inner cylinder 21, a jacket 22 and a guide plate 23. The guide plate 23 includes a plurality of annular plates disposed between the inner cylinder 21 and the jacket 22. The outer surface of the inner cylinder 21, the inner surface of the jacket 22 and the guide plate 23 can form a channel for the flow of liquid such as a heat exchange medium.
[0032] The guide plate 23 may include a first guide plate 231 and a second guide plate 232. The first guide plate 231 is provided with an outer notch 2311, which is provided at the radially outer side of the first guide plate 231, and the structure radially inside the outer notch 2311 of the first guide plate 231 is a complete circular ring structure. The second guide plate 232 is provided with an inner notch 2321, which is provided at the radially inner side of the second guide plate 232, and the structure radially outside the inner notch 2321 of the second guide plate 232 is a complete circular ring structure.
[0033] In one embodiment of the present application, the first guide plate 231 is parallel to the cross section of the inner tube 21, and the second guide plate 232 is parallel to the cross section of the inner tube 21, which is convenient for installation. The first guide plate 231 and the second guide plate 232 are arranged alternately, and there is only one outer notch 2311 on the first guide plate 231, and there is only one inner notch 2321 on the second guide plate 232, and on the plane where the guide plate 23 is located, the orthographic projection of the outer notch 2311 and the orthographic projection of the inner notch 2321 differ by 180° or other angles in the circumferential direction of the guide plate 23. See Figure 6 , Figure 7 , the heat exchange medium can travel in the liquid channel formed by the guide plate 13, Figure 7 The black arrow in the middle indicates the flow direction of the heat exchange medium. The heat exchange medium can flow across the layers through the outer notch 2311 and the inner notch 2321. It can be understood that Figure 3 The guide plate 23 in the figure uses a simple drawing method. The shape of the guide plate and the position of the notch on the guide plate can be referred to Figure 4 , Figure 5 , Figure 6 .
[0034] The jacketed container may further include a liquid inlet and a liquid outlet connected to the liquid channel formed by the inner cylinder 21, the guide plate 23 and the jacket 22, for inputting and outputting heat exchange medium, and the cross-sectional areas of the liquid inlet and the liquid outlet may be the same or differ by no more than 10% of the cross-sectional area of the smaller liquid inlet. The cross-sectional areas of the outer notch 2311 and the inner notch 2321 may be the same or differ by no more than 10% of the cross-sectional area of the smaller notch. In one embodiment, the cross-sectional area of the outer notch 2311 and / or the inner notch 2321 is 1.5 to 2 times or more the cross-sectional area of the liquid inlet and / or the liquid outlet.
[0035] The notches in the embodiment of the present application are alternately arranged outer notches 2311 and inner notches 2321, and the heat exchange medium can be switched between near the inner tube 21 and near the jacket 22. In other words, especially at the notches, the heat exchange medium on the inner peripheral side (inner layer) can flow to the moving outer peripheral side (outer layer), and the heat exchange medium on the outer peripheral side (inner layer) can flow to the moving inner peripheral side (inner layer). The temperature of the heat exchange medium is more balanced and the heat exchange effect is excellent.
[0036] It can be understood that when the notches on the guide plate 23 are outer notches 2311 and inner notches 2321 as a whole, especially when the notches in different layers are located in a corresponding position, the heat exchange medium close to the inner cylinder 21 is always close to the inner cylinder 21, or the heat exchange medium close to the jacket 22 is always close to the jacket 22. The embodiment of the present application in which the inner and outer notches are alternately arranged has a better mixing effect of the heat exchange medium, a more uniform temperature, and thus a better heat exchange effect.
[0037] In the embodiment of the present application, each layer of the guide plate 23 can be provided with only one notch (inner notch 2321 or outer notch 2311), and the notches of the guide plates 23 of adjacent layers are separated by 180° or other angles. That is, on the plane where a guide plate 23 is located, the orthographic projections of the notches of the guide plates of adjacent layers, such as the orthographic projection of the outer notch 2311 and the orthographic projection of the inner notch 2321, can be separated by an angle a in the circumferential direction of the guide plate 23, which satisfies 90°≤a≤180°. Of course, when each layer of the guide plate 23 has multiple notches (not shown in the figure), the orthographic projection of the outer notch 2311 and the orthographic projection of the inner notch 2321 can also be separated by an angle a in the circumferential direction of the guide plate 23, which satisfies 90°≤a<180°. That is, the interval angle between the closest outer notch 2311 and inner notch 2321 on the two layers of guide plates 23 is not less than 90°.
[0038] The circumference of the notch may be 1 / 4 or less of the circumference of the guide plate, for example, 1 / 6, 1 / 8, 1 / 10, 1 / 12, 1 / 15, 1 / 20, etc. of the circumference of the guide plate.
[0039] It can be understood that due to the effect of pressure, the heat exchange medium will cross the layer from the nearest notch distance. There are multiple notches on the guide plate of each layer or a single-layer guide plate has a notch, but the notch positions of the upper and lower layers correspond, especially when the heat exchange medium moves from top to bottom in the jacket container (not shown in the figure), the heat exchange medium cannot go around for a week, and the heat exchange medium cannot fully contact the inner cylinder 21. However, in the embodiment of the present application, only one notch is set in each layer, and the notch interval is, for example, 180°, so that the heat exchange medium can go around the outer surface of the inner cylinder 21, the inner surface of the jacket 22, and the channel formed by the guide plate 23 before going to other layers. The heat exchange medium can fully contact the inner cylinder 21, and the heat exchange effect is better. When there are multiple notches in each layer, the notches of adjacent layers are separated by a large angle, which can also achieve the effect of making the heat exchange medium fully contact with the inner cylinder 21.
[0040] The outer surface of the inner cylinder 21 may have external structures such as a pipe, an ear seat, etc. The three-dimensional spiral guide plate needs to be manufactured and installed after the orientation and elevation of these external structures are determined. The guide plate 23 in the embodiment of the present application is a relatively regular annular shape, the shape of its notch is also relatively regular, and the guide plates 23 are arranged in parallel. In the face of inner cylinders 21 with different elevations, the manufacture and installation of the guide plate 23 in the embodiment of the present application are relatively simple, so that the production cycle of the jacketed container is relatively short.
[0041] See also Figure 4 The first guide plate 231 shown has a complete circular ring shape on the inner side of the first guide plate 231 that contacts the inner tube 23, so that the calculation formula of the reinforcement ring can be applied to the first guide plate 231. Compared with the spiral guide plate structure, the present application can easily calculate various values when the first guide plate 231 is used as a reinforcement ring, and then can easily calculate the reduced value of the thickness of the inner tube 21.
[0042] The first guide plate 231 and the inner tube 21 can be welded and fixed, for example, they can be welded continuously on both sides, and the first guide plate 231 can play the role of a reinforcement ring. The second guide plate 232 cannot be directly sleeved with a reinforcement ring due to the inner notch 2321, and it can be connected to the inner tube 21 by intermittent welding, and the second guide plate 232 can not be used as a reinforcement ring. In order to prevent leakage, sealing materials such as sealants can be provided between the guide plate 23 and the inner tube 21, and between the guide plate 23 and the jacket 22.
[0043] It can be understood that the inner cylinder 21 may include a cylindrical region and convex regions at both ends of the cylindrical region. Non-parallel guide plates 23 may be provided outside the convex region at the bottom of the inner cylinder 21. The first guide plate 231 and the second guide plate 232 provided in parallel may be provided correspondingly in the cylindrical region of the inner cylinder 21 and its vicinity.
[0044] Although the present application has been described with reference to exemplary embodiments, it should be understood that the present application is not limited to the disclosed exemplary embodiments. Those skilled in the art can make various modifications and changes to the above embodiments under the guidance of the present application without departing from the scope of the present application.
