Technical Field

[0001] The utility model relates to the field of cooling of a reaction kettle, in particular to a reaction kettle with a cooling mechanism. Background Art

[0002] Dyes refer to a class of organic compounds that can endow other substances with bright and firm colors. In the processing of dyes, a variety of raw materials or reactants need to be poured into a reaction kettle for mixing and reaction. Some reactions require a lower reaction temperature, but a large amount of heat will be released during the reaction process. In order to avoid the occurrence of runaway reactions or side reactions, it is necessary to cool the reaction kettle in time;

[0003] The cooling method that our company has been using is to make the reaction kettle into a double-layer structure, and flowing water is introduced into the cavity of the hollow layer;

[0004] The above method requires a continuous supply of cold water. However, the circulation time of cold water in the reaction kettle is short, and sufficient heat exchange cannot be carried out. At the same time, the reaction kettle is relatively large, and a large amount of cold water needs to be stored for circulation. At the same time, it is necessary to prepare large-volume and multiple cold water pools for the circulating water to be cooled;

[0005] It is not conducive to the utilization of water resources, and the structure is relatively cumbersome. Content of the Utility Model

[0006] The utility model provides a reaction kettle with a cooling mechanism. By setting the heat exchange chamber inside the reaction kettle body as a spiral chamber, the medium water walks along a spiral trajectory in the heat exchange chamber, effectively prolonging the contact time between the medium water and the reaction kettle body, enabling sufficient heat exchange, thereby effectively improving the heat exchange efficiency, reducing the usage amount of the medium water, reducing the number of water storage pools at the same time, effectively reducing the floor area, and saving more space and funds.

[0009] A flow rate reduction structure is arranged in the heat exchange chamber.

[0010] Further, the flow rate reduction structure includes spiral blades;

[0011] The inner side edge of the spiral blade is welded to the outer peripheral surface of the reaction kettle body;

[0012] The outer side edge of the spiral blade is welded to the inner peripheral surface of the shell;

[0013] The heat exchange chamber is a spiral heat exchange chamber, and the spiral heat exchange chamber is formed between the outer peripheral side of the reactor body, the spiral blades and the inner peripheral surface of the housing.

[0014] Furthermore, the reactor body is a semi-ellipsoidal shell;

[0015] Correspondingly, the housing is a semi-ellipsoidal shell.

[0016] Furthermore, the housing is a spiral housing, and the spiral housing is welded to the outer peripheral side of the reactor body along a spiral trajectory;

[0017] The spiral housing includes a spiral bottom plate, a spiral top plate and spiral side plates. The spiral bottom plate and the spiral top plate are respectively located at the upper and lower ends of the spiral side plates, and the inner sides of the spiral bottom plate and the spiral top plate are simultaneously welded to the outer peripheral side of the reactor body;

[0018] The spiral bottom plate or the spiral top plate forms the spiral blades.

[0019] Furthermore, heat conducting sheets are arranged on the outer peripheral side of the reactor body, and the heat conducting sheets extend into the heat exchange chamber.

[0020] Furthermore, a water inlet is arranged at the bottom of the heat exchange chamber, and a water outlet is arranged at the top of the heat exchange chamber.

[0021] In the utility model, by arranging the heat exchange chamber inside the reactor body as a spiral chamber, the medium water walks along a spiral trajectory in the heat exchange chamber, effectively prolonging the contact time between the medium water and the reactor body, enabling sufficient heat exchange, thereby effectively improving the heat exchange efficiency, reducing the usage amount of the medium water, reducing the number of water storage pools at the same time, effectively reducing the floor area, and saving more space and funds.

Specific embodiments

[0027] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0028] In the specific embodiment of the present invention, see Figures 1-3 , a reactor with a cooling mechanism includes: a reactor body 1 and an outer shell 2, the outer shell 2 is sleeved on the outer peripheral side of the reactor body 1, and a heat exchange chamber 3 is formed between the reactor body 1 and the outer shell 2;

[0029] A flow rate reduction structure 4 is arranged in the heat exchange chamber 3;

[0030] Since water exchanges heat with the reactor body after entering the heat exchange chamber, in order to improve the heat exchange efficiency of the medium water, a flow rate reduction structure is arranged in the heat exchange chamber. The flow rate reduction structure can reduce the flow rate of the water flow, thereby prolonging the contact time between the medium water and the reactor body, making the heat exchange more thorough, making full use of the heat exchange properties of the medium water, thereby improving the heat exchange efficiency, ensuring that the temperature difference of the reactor body will not have too large a fluctuation, and thus ensuring the normal and orderly progress of the reaction.

[0031] In the specific embodiment of the present invention, see Figures 1-3 , the flow rate reduction structure 4 includes a spiral blade 41;

[0032] The inner side of the spiral blade 41 is welded to the outer peripheral surface of the reactor body 1;

[0033] The outer side of the spiral blade 41 is welded to the inner peripheral surface of the outer shell 2;

[0034] The heat exchange chamber 3 is a spiral heat exchange chamber, and the spiral heat exchange chamber is formed between the outer peripheral side of the reactor body 1, the spiral blade 41 and the inner peripheral surface of the outer shell 2;

[0035] The spiral heat exchange chamber is a spiral channel. The medium water passes through the spiral channel, and its traveling path is extended, thereby prolonging the contact time with the reactor body, and thus being able to make more full use of the heat exchange property of the medium water and ensuring higher heat exchange efficiency.

[0036] In a specific embodiment of the present utility model, see Figures 1-3 , in order to make the connection between the spiral blade and the reactor body smoother, the reactor body 1 is set as a semi-ellipsoidal shell;

[0037] Correspondingly, the outer shell is a semi-ellipsoidal shell.

[0038] In a specific embodiment of the present utility model, see Figures 1-3 , the outer shell 2 is a spiral outer shell 5, and the spiral outer shell 5 is welded to the outer peripheral side of the reactor body 1 according to a spiral trajectory;

[0039] The spiral outer shell 5 includes a spiral bottom plate 51, a spiral top plate 52 and spiral side plates 53. The spiral bottom plate 51 and the spiral top plate 52 are respectively located at the upper and lower ends of the spiral side plates. The inner sides of the spiral bottom plate 51 and the spiral top plate 52 are simultaneously welded to the outer peripheral side of the reactor body 2;

[0040] The spiral bottom plate 51 or the spiral top plate 52 forms the spiral blade 41;

[0041] That is, the semi-ellipsoidal shell 2 is formed by welding the spiral side plates 53.

[0042] In a specific embodiment of the present utility model, see Figures 1-3 , a heat conducting sheet 11 is arranged on the outer peripheral side of the reactor body 1. The heat conducting sheet 11 is welded to the outer peripheral side of the reactor body, and the heat conducting sheet 11 extends into the heat exchange chamber 3;

[0043] Multiple circles of heat conducting sheets are arranged, and multiple heat conducting sheets are arranged in each circle;

[0044] By arranging the heat conducting sheet, the heat of the reactor can be transferred to the heat conducting sheet faster, effectively expanding the heat conducting area and improving the heat exchange efficiency;

[0045] The heat conducting sheet is arranged obliquely with respect to the water flow direction, which can block the water flow to a certain extent and slow down the water flow velocity, thereby further improving the heat exchange efficiency.

[0046] In a specific embodiment of the present utility model, see Figures 1-3 , a water inlet 31 is arranged at the bottom of the heat exchange chamber 3, and a water outlet 32 is arranged at the top;

[0047] The medium water flows spirally from the bottom to the top, and during this process, it can fully take away the heat of the reactor body and sufficiently cool down the reactor body.

[0048] When actually welding the spiral outer shell to the reactor body, a welding gap is left between the adjacent lower top plate and the upper bottom plate to ensure the normal progress of welding.

[0049] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
