Description

Technical Field

[0001] This utility model relates to the field of reaction vessels, and more specifically, to a heat dissipation reaction vessel. Background Technology

[0002] In industries such as chemical, pharmaceutical and food processing, reaction vessels are indispensable core equipment. Chemical reactions often take place inside them under extreme conditions such as high temperature, high pressure and strong corrosion. They are mainly used to complete processes such as sulfidation, nitration, hydrogenation, hydrocarbonation, polymerization and condensation, and are important containers for realizing physical or chemical reactions.

[0003] In the room where the reactor is stored, there may be volatile raw materials in the ingredients or finished products, and substances in the air that are easily soluble in water or react with water. When the reactor is undergoing an exothermic reaction, a large amount of heat will be generated on its surface. For the purpose of protecting the reactor, an outer shell is usually installed on its surface to resist external impacts. However, in actual use, the outer shell often develops holes due to its resistance to external impacts. When materials are added to the reactor, some materials may accidentally fall into the area between the reactor and the outer shell through these holes. In addition, ambient humidity and moisture can also easily fall into the area through these holes. Furthermore, for economic reasons, only the internal surface is usually treated to prevent reaction (surface treatment, coating, etc.), resulting in weak corrosion resistance of the outer surface of the reactor. The heat generated by the reactor is transferred through the reactor wall to the area between the outer shell and the reactor, where heat accumulates. These corrosive media and water mix and are heated, which in turn corrodes the surface of the reactor wall and affects the service life of the reactor.

[0004] Therefore, a new technical solution is needed to address the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a heat dissipation reactor.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: it includes a reaction vessel inner liner, an outer shell is installed on the outer liner, a vessel lid is installed on the top of the outer shell, there is a gap between the inner wall of the outer shell and the reaction vessel inner liner, a base is provided at the bottom of the outer shell, a bottom support is fixedly connected to the top surface of the base, the top surface of the bottom support abuts against the top surface of the reaction vessel inner liner, and a through groove is opened on the top surface of the base near the outer shell, the through groove connecting the inner cavity of the outer shell with the outside.

[0007] By adopting the above technical solution, this device installs an outer shell on the outer wall of the reactor inner liner. The outer shell protects the reactor inner liner and can insulate it. When an exothermic reaction occurs inside the reactor inner liner, external water vapor will adhere to the surface. Without the installation of the outer shell, the water vapor in the air would directly adhere to the outer wall of the reactor inner liner. The gap between the outer shell and the reactor inner liner can provide appropriate insulation. When an endothermic reaction occurs inside the reactor, the low-temperature gas density is relatively high, thus flowing towards the bottom channel.

[0008] The present invention is further configured such that: a plurality of protrusions are fixedly connected to the inner wall of the outer shell, the protrusions are spaced at the same distance, and a heat-insulating material is placed between two of the protrusions.

[0009] By adopting the above technical solution, several protruding strips are fixedly connected inside the shell, and heat insulation cotton can be installed between the protruding strips to further improve the heat insulation effect of the reactor.

[0010] The present invention is further configured such that the upper opening and the lower opening of the through groove are set at an angle.

[0011] By adopting the above technical solution, the inverted trapezoidal groove can provide better structural stability. Due to its wider top and narrower bottom, this design can effectively resist external pressure and deformation.

[0012] The present invention is further configured such that there is a gap between the convex strip and the inner liner of the reactor.

[0013] By adopting the above technical solution, a gap is left between the convex strip and the outer wall of the reactor inner liner, which can reduce the heat transfer effect of the reactor to the shell.

[0014] The present invention is further configured such that: a handle is installed at the top of the lid, and a hinge is rotatably connected to the lid and the outer shell.

[0015] By adopting the above technical solution, the lid is connected to the outer shell and the connection point by a hinge, and the lid can be pulled by a handle.

[0016] The present invention is further configured such that: a plurality of control devices are installed on the top of the vessel lid, the control devices including a refrigeration device, a heating device, a ventilation pipe and a pressurization device, and a pipe cap is threadedly connected to the top of the ventilation pipe.

[0017] By adopting the above technical solution, a control device is installed on the top of the reactor lid. The control device includes a cooling device, a heating device, a ventilation pipe, and a pressurizing device. The control device cools, heats, pressurizes, and ventilates the reactants in the reactor.

[0018] In summary, this utility model has the following beneficial effects: By installing an outer shell on the outer wall of the inner liner of the reactor, leaving a gap between the outer shell and the reactor, and opening a through groove at the bottom, the device can enhance the air circulation around the reactor, which helps to dissipate heat and reduce the temperature. High temperature is an important factor that accelerates corrosion. Therefore, improving heat dissipation conditions can indirectly slow down the corrosion rate. Especially in reactions containing corrosive media, reducing the temperature can reduce the occurrence of corrosion reactions. Attached Figure Description

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0024] A heat dissipation reactor, such as Figure 1 As shown, the reactor includes an inner liner and an outer shell 2 installed on the outside of the inner liner. The inner liner is located inside the cavity of the outer shell 2. A lid 1 is installed on the top of the outer shell 2. There is a gap between the inner wall of the outer shell 2 and the inner liner. A base 3 is provided at the bottom of the outer shell 2. A base support 31 is fixedly connected to the top surface of the base 3. The top surface of the base support 31 abuts against the top surface of the inner liner. A through groove 32 is provided on the top surface of the base 3 near the outer shell 2, which connects the inner cavity of the outer shell 2 to the outside. A handle 11 is installed on the top of the lid 1. A hinge 16 is rotatably connected to the lid 1 and the outer shell 2.

[0025] like Figure 2 As shown, the upper and lower openings of the through groove 32 are set at an angle.

[0026] like Figure 3 As shown, several protrusions 21 are fixedly connected to the inner wall of the outer shell 2. The distance between the protrusions 21 is the same. A heat insulation material is placed between two protrusions 21. There is a gap between the protrusions 21 and the inner liner of the reactor.

[0027] This device uses an outer shell 2 installed on the outer wall of the reactor inner liner. The outer shell 2 protects the reactor inner liner and provides insulation. When there are reactants requiring low temperatures inside the reactor inner liner, external water vapor will adhere to the surface. Without the outer shell 2, water vapor in the air would adhere to the outer wall of the reactor inner liner. The gap between the outer shell 2 and the reactor inner liner reduces heat transfer during reactor cooling, minimizing condensation of external water vapor on the outer shell 2 and reducing corrosion of both the reactor and the outer shell 2. A base 3 is installed at the bottom of the outer shell, and a bottom support 31 abuts against the bottom of the reactor inner liner at the top of the base 3. The bottom support 31 stabilizes the spherical reactor bottom. The angled design... The opening of the through groove 32 can be enlarged. When the air between the reactor and the reactor contains water vapor during the cooling reaction, the condensed water falling into the base 3 can flow into the through groove 32 at an angle, allowing the water to drain out more efficiently. When the reactor is heated, the through groove 32 at the bottom of the base 3 can ventilate the space between the shell and the reactor, reducing the problem of poor ventilation inside the reactor. Several protrusions 21 are fixedly connected inside the shell. Heat insulation cotton can be installed between the protrusions 21 to further insulate the reactor. The gap between the protrusions 21 and the outer wall of the reactor inner liner can reduce the heat transfer effect from the reactor to the shell.

[0028] A control device is installed at the top of the vessel lid 1. The control device includes a cooling device 12, a heating device 13, a ventilation pipe 14, and a pressurizing device 15. The control device cools, heats, pressurizes, and ventilates the reactants in the reactor. A handle 11 is installed at the top of the vessel lid 1 to make it easier to open the vessel lid 1 by rotating it through the hinge 16.

[0029] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
