Description

Technical Field

[0001] The utility model relates to the technical field of reactors, in particular to a strong heating reactor device. Background Art

[0002] With the development of large-scale chemical industry, the main equipment reactor is also getting larger and larger. However, the heating time is too long, which seriously affects production efficiency. For example, the publication number CN117983158A discloses a steam-heated reactor, which includes a vertically arranged reactor body, a stirring shaft disposed at the center of the reactor body, a stirring blade disposed on the stirring shaft, and one or at least two circumferentially spaced mounting sleeves disposed on the side wall of the reactor body. The reactor also includes steam nozzles corresponding to the number of mounting sleeves, with the upper end of the steam nozzle being an air inlet end and the lower end being an air outlet end. The steam nozzles are positioned and inserted into the inner holes of the corresponding mounting sleeves. Although the patent connects the air inlet end of the steam nozzle to the steam pipe, so that the steam outlet end of the steam nozzle can pass high-temperature steam into the material in the reactor body to achieve direct heating of the material, the heating efficiency is still low when heating large reactors. Therefore, during long-term research and development testing, it was found that the heat exchange efficiency of large reactors in the prior art is low due to the long heating time.

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments. Example

[0019] like Figure 1 and Figure 2 As shown, a strong heating reactor device comprises: a body 11; a head 2 is fixedly installed at the bottom of the body 11 by bolts, a circulation inlet 1 communicating with the interior of the body 11 is fixedly installed at the middle part below the head 2 by bolts, a guide tube 3 is provided inside the body 11, and a tube sheet 4 is fixedly installed at the top and bottom of the guide tube 3 by bolts, a plurality of heat exchange tubes 6 are fixedly installed between two of the tube sheets 4 by bolts, and the plurality of heat exchange tubes 6 are distributed in a ring shape inside the body 11, a heat medium inlet 5 communicating with the heat exchange tube 6 is fixedly installed on one side of the outer periphery of the body 11 near the bottom end by bolts, a heat medium outlet 7 communicating with the heat exchange tube 6 is fixedly installed on one side of the outer periphery of the body 11 near the top end by bolts, a stirring system 8 is provided in the body 11, a circulation outlet 9 communicating with the interior of the body 11 is fixedly installed on the other side of the outer periphery of the body 11 by bolts, a discharge port 10 is provided on both sides of the middle part below the bottom of the head 2, and an expandable and contractible deformation component is provided inside the body 11.

[0020] Among them, a hollow tube-type heat exchange tube 6 is provided in the internal middle section of the main body 11, so that the heat medium input through the heat medium inlet 5 can enter the heat exchange tube 6 for heating, and then discharge the heat outward through the heat medium outlet 7 after transferring the heat to the main body 11, thereby circulating to supply heat to the main body 11. When heating the inside of the reactor, a propulsion stirring system 8 is adopted in the main body 11 to increase the axial flow of the airflow inside the reactor, so that the material inside the reactor can roll up and down and flow through the heat exchange tube 6, thereby effectively increasing the heat exchange efficiency. At the same time, by adding a circulation inlet 1 and a circulation outlet 9 at the bottom and side of the main body 11 respectively, the heat exchange effect can be further enhanced, thereby effectively shortening the problem of long heating time inside the large reactor.

[0021] like Figure 1 and Figure 2 As shown, the stirring system 8 includes: a support frame 12, which is fixedly installed at the top center of the main body 11 by bolts, a motor 13 is fixedly installed on the top of the support frame 12 by bolts, the power output end of the motor 13 passes through the support frame 12 and penetrates into the main body 11 and is fixedly installed with a guide rod 14 by bolts, and a stirring blade 15 is fixedly installed at the bottom end of the guide rod 14 by bolts, and the stirring blade 15 is located between adjacent sides of multiple heat exchange tubes 6, and the central axis of the stirring blade 15 is coaxially arranged with the virtual center line of the circulation inlet 1.

[0022] Among them, the guide rod 14 is driven by the motor 13 to drive the stirring blade 15 to rotate in the reactor, so that the gas inside the body 11 can form an axial airflow, thereby driving the material inside the reactor to flow, further increasing the flow efficiency of heat inside the reactor and improving the heating effect inside the reactor. Example

[0023] Further, such as Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the expandable and contractible deformation component includes: a positioning plate 16 fixedly installed on the periphery of the guide rod 14 near both ends by bolts, and a return spring 17 is fixedly installed on the adjacent sides of the two positioning plates 16 by bolts, and a sliding plate 18 is fixedly installed on the end of the return spring 17 away from the positioning plate 16 by bolts, and the sliding plate 18 is slidably sleeved on the periphery of the guide rod 14, and a plurality of brackets 19 distributed at the same intervals are hinged on the edges around the periphery of the sliding plate 18, and the adjacent ends of two adjacent brackets 19 in the vertical direction are fixedly installed with magnets 20 by bolts, and a heat-resistant bag is provided between the brackets 19.

[0024] Among them, the guide rod 14 driven by the motor 13 can drive the positioning disk 16 to rotate. As the speed of the guide rod 14 increases, the centrifugal force allows each bracket 19 to open away from one end of the sliding disk 18, so that the heat-resistant bag can be propped up, making the volume of the heat-resistant bag larger, thereby reducing the space size inside the reactor, allowing heat to be further quickly diffused into the entire cavity, further accelerating the heating efficiency inside the reactor, and making the heating speed inside the large reactor faster, thereby effectively improving the heating effect inside the reactor. When the rotation of the guide rod 14 is reduced, the vertically adjacent brackets 19 can be stored with the help of the magnetic adsorption effect of the magnet 20 between adjacent brackets 19, so as to realize the folding and storage of the heat-resistant bag.

[0025] like Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the heat-resistant bag includes: a first folding flap 21 fixedly installed between multiple brackets 19 located on the upper and lower sides of the guide rod 14 by bolts, a second folding flap 22 is sleeved on the middle part of the outer periphery of the guide rod 14, and the two side edges of the second folding flap 22 are respectively fixedly connected to the two first folding flaps 21 by bolts, and the outer periphery of the first folding flap 21 and the outer periphery of the second folding flap 22 are coated with a heat-resistant layer.

[0026] Among them, by cooperating with the first folding flap 21 and the second folding flap 22, the volume can be changed with the help of the support effect of the bracket 19, thereby achieving the effect of adjusting the volume of the internal cavity of the reactor. By occupying the middle space of the reactor, the heat can be quickly diffused to the surroundings, further accelerating the heating effect of the large reactor, saving heating time and improving processing efficiency.
