Description

Technical Field

[0001] This invention relates to the field of energy-saving technology for reactors, specifically to an energy-saving reactor and its energy-saving method. Background Technology

[0002] A reaction vessel is a common tool in chemical production processes. It provides a reaction space for raw materials, allowing production personnel to pour the raw materials needed for product preparation into the reaction vessel and use catalysts, mechanical equipment, etc., to carry out reactions such as heating, catalysis, and cooling to obtain the desired production materials. However, reaction vessels vary depending on different production processes and operating conditions, resulting in different design structures and parameters. Therefore, reaction vessels are non-standard container equipment.

[0003] In existing production processes, the reactor is generally set up independently. During the reaction, the material is introduced into the reactor and heated or cooled. The material begins to react within the reactor under the action of mechanical structures such as stirring equipment, maintaining high reaction efficiency. This is accompanied by exothermic and endothermic reactions. Therefore, in order to accommodate these special reaction results, the reactor needs to undergo corresponding cooling and heating processes, thus requiring the provision of appropriate cooling and heating equipment.

[0004] However, in actual use, the above-mentioned equipment is usually used alone. After the corresponding production reaction, the reactor needs to be cleaned or discharged. During this process, the heat of the reactor itself is naturally dissipated, i.e., naturally cooled. However, it needs to be reheated when the reactor is used for production again, which not only wastes energy, but also greatly reduces the production utilization efficiency of the reactor. In view of this, we propose an energy-saving reactor and its energy-saving method. Summary of the Invention

[0005] The purpose of this invention is to provide an energy-saving reactor and its energy-saving method to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an energy-saving reactor, comprising a housing, wherein a reactor body is fixedly installed inside the housing, and a heat exchange assembly is disposed inside the housing, the heat exchange assembly comprising: A suction pump is fixedly installed on the inner wall of the housing, and the output end of the suction pump is fixedly connected to the end of a connecting pipe. A spiral heat exchange tube is provided, with the other end of the connecting tube fixedly connected to the end of the spiral heat exchange tube. A flow-blocking plug is provided on the inner wall of the spiral heat exchange tube, and an anti-blocking mesh is fixedly installed on the inner wall of the end of the connecting tube.

[0007] Preferably, the top inner wall of the outer casing has two mounting slots of a size that are adapted to the reactor body, and the reactor body is provided in two sets, with the two sets of reactor bodies arranged symmetrically about the central axis of the outer casing. The spiral heat exchange tubes are provided in two sets, and the two sets of spiral heat exchange tubes are respectively installed on the outer wall of the two sets of reactor bodies.

[0008] Preferably, the spiral heat exchange tube is arranged in a spiral shape, and the body of the spiral heat exchange tube is made of stainless steel. The outer wall of the spiral heat exchange tube near the reactor body is tightly attached to the arc-shaped outer wall of the reactor body to achieve the best heat exchange efficiency between the reactor body and the spiral heat exchange tube.

[0009] Preferably, the spiral heat exchange tube is hollow inside and filled with heat-conducting oil, so that a portion of the heat emitted during the reaction in the reactor body can be transferred to the heat-conducting oil through the spiral heat exchange tube.

[0010] Preferably, the ejection assembly includes a sleeve, through which the anti-blocking net passes and is fixedly connected to the anti-blocking net. A telescopic rod is fixedly connected to the inner wall of the sleeve near the suction pump, and an ejection slide rod is fixedly connected to the other end of the telescopic rod. A contact plate is fixedly connected to the other end of the ejection slide rod. A return spring is fixedly connected to the inner wall of the sleeve near the suction pump, and the other end of the return spring is fixedly connected to the end face of the ejection slide rod.

[0011] Preferably, the sleeve has a through hole at the center of the end away from the suction pump, with a diameter that matches the outer diameter of the ejector slide rod, and the ejector slide rod is slidably installed in the through hole so that the ejector slide rod can slide along the through hole.

[0012] Preferably, the sleeve is provided with an auxiliary abutment component, which includes a fixed slide rod. The fixed slide rod is fixedly connected to the inner surface of the through hole opened at the end of the sleeve away from the suction pump. The end of the fixed slide rod is hinged to the end of a hinged slide rod, and the other end of the hinged slide rod is fixedly connected to an abutment ball.

[0013] Preferably, the outer arc-shaped wall of the ejector slide rod is provided with a groove that matches the fixed slide rod, so that the ejector slide rod can be limited by the fixed slide rod when it slides along the inner wall of the sleeve.

[0014] An energy-saving method for an energy-saving reactor includes the following steps: S1. After the reaction in the reactor body on the left side of the outer shell is completely finished, start the suction pump to exchange the heat transfer oil in the spiral heat exchange tubes on both sides of the outer shell. S2. After the heat exchange in the spiral heat exchange tubes on both sides of the outer casing has been completely exchanged, turn off the suction pump. S3. Wait 10 minutes to allow the reactor body on the right side of the outer casing to fully exchange heat with the heat transfer oil in the threaded heat exchange tube, so as to achieve full utilization of heat energy and energy saving.

[0015] Compared with the prior art, the present invention provides an energy-saving reactor and its energy-saving method, which has the following beneficial effects: 1. This energy-saving reactor and its energy-saving method, in order to improve thermal energy utilization and reduce energy consumption in chemical reactions, are equipped with heat exchange components. These components, along with threaded heat exchange tubes located on the outer sides of two reactor bodies and filled with heat transfer oil, are directionally drawn in with the assistance of a suction pump. This allows the heat-carrying oil to be transferred to the threaded heat exchange tubes on the outer sides of reactor bodies that have not yet begun reaction after the reaction in one reactor body has ended. Through the heat transfer oil and suction pump, combined with two sets of spiral heat exchange tubes located on the outer sides of the reactors, heat exchange between the two reactor bodies can be achieved without additional heat exchangers. Furthermore, the trapping plugs inside the spiral heat exchange tubes provide temporary storage space for the heat transfer oil, eliminating the need for additional containers to hold the materials after heat exchange. This allows operators to more conveniently and easily discharge and load materials from the reactor bodies.

[0016] 2. This energy-saving reactor and its energy-saving method, in order to prevent the throttling plug from completely sealing the anti-blocking net when the suction pump is started, is equipped with an ejector component. With the elasticity of the reset spring, the ejector slide rod can cooperate with the contact plate with a hemispherical surface on the right side to provide ejection protection for the throttling plug, preventing it from sliding out of the spiral heat exchange tube and blocking the connecting pipe, which would prevent the heat transfer oil from being efficiently suctioned and repositioned, thus affecting the normal use of the device.

[0017] 3. This energy-saving reactor and its energy-saving method, in order to avoid excessive suction generated during the operation of the suction pump causing the shut-off plug to excessively squeeze the contact plate, is equipped with an abutment component. This component, together with the fixed slide rod and the hinged slide rod, moves on the arc-shaped outer wall of the contact plate. This causes the abutment ball to move to the left relative to the contact plate and simultaneously move away from the center of the contact plate, thereby expanding the area enclosed by the contact plate and the abutment ball. This increases the force-bearing points of the shut-off plug, improves the shut-off protection effect of the shut-off plug, and prevents it from breaking, which would affect the subsequent protection effect on the spiral heat exchange tube.

[0020] like Figures 1-6 As shown, the present invention provides a technical solution: an energy-saving reactor and its energy-saving method, comprising a casing 1, a reactor body 2 fixedly installed inside the casing 1, a heat exchange assembly provided inside the casing 1, the heat exchange assembly including a suction pump 3, the suction pump 3 fixedly installed on the inner wall of the casing 1, the output end of the suction pump 3 fixedly connected to the end of a connecting pipe 4, the other end of the connecting pipe 4 fixedly connected to the end of a spiral heat exchange tube 5, the inner wall of the spiral heat exchange tube 5 being provided with a flow-blocking plug 6, and the inner wall of the end of the connecting pipe 4 being fixedly installed with an anti-blocking mesh 7.

[0021] In one embodiment of the present invention, two mounting slots of a size adapted to the reactor body 2 are provided on the top inner wall of the outer casing 1. Two sets of reactor bodies 2 are provided, symmetrically arranged about the central axis of the outer casing 1. A barrier device is provided between the two sets of reactor bodies 2 to prevent mutual interference during chemical production reactions, ensuring the safety of the chemical reaction inside the reactor bodies 2. Furthermore, the suction pump 3 is electrically connected to external AC power, using 220V AC power. A controller is installed inside the outer casing 1, controlling the start and stop of the suction pump 3 through its internal control program. Simultaneously, two sets of spiral heat exchange tubes 5 are provided, and the two sets of spiral heat exchange tubes... The tubes 5 are respectively installed on the outer walls of the two sets of reactor bodies 2. Specifically, the spiral heat exchange tubes 5 are spiral in shape, and the body of the spiral heat exchange tubes 5 is made of stainless steel. At the same time, the outer wall of the spiral heat exchange tubes 5 near the reactor body 2 is closely attached to the arc-shaped outer wall of the reactor body 2, so that the spiral heat exchange tubes 5 and the reactor body 2 maintain the maximum contact area and achieve the best heat exchange efficiency between the reactor body 2 and the spiral heat exchange tubes 5. Furthermore, the interior of the spiral heat exchange tubes 5 is hollow and filled with heat transfer oil. The heat transfer oil completely fills the internal cavity of the spiral heat exchange tubes 5, so that during the reaction in the reactor body 2, some of the heat dissipated can be transferred to the heat transfer oil through the spiral heat exchange tubes 5.

[0022] In an embodiment of the present invention, two sets of flow-blocking plugs 6 are provided, and the two sets of flow-blocking plugs 6 are respectively located at the top and bottom of the spiral heat exchange tube 5. Specifically, the heat transfer oil is filled in the cavity of the spiral heat exchange tube 5 between the two sets of flow-blocking plugs 6, so that the two sets of flow-blocking plugs 6 can restrict the position of the heat transfer oil and prevent it from flowing freely in the spiral heat exchange tube 5, which would affect the subsequent heat transfer oil discharge effect. Furthermore, the inner diameter of the connecting pipe 4 is larger than the end cross-section of the flow-blocking plug 6, so that when the suction pump 3 is started to pump the heat transfer oil in the spiral heat exchange tube 5, the channel between the spiral heat exchange tube 5 and the connecting pipe 4 can be opened by changing the position of the flow-blocking plug 6, so that the heat transfer oil can flow out normally and be pumped out by the suction pump 3 to another set of spiral heat exchange tubes 5. In addition, by providing an anti-blocking net 7, it is prevented that the flow-blocking plug 6 slides into the interior of the connecting pipe 4, causing the suction pump 3 to be unable to carry out the suction activity normally, which would affect the normal heat exchange effect of the heat transfer oil.

[0023] In addition, to prevent the throttling plug 6 from completely sealing the anti-blocking net 7 when the suction pump 3 is started, an ejection assembly is provided inside the connecting pipe 4. The ejection assembly includes a sleeve pipe 8. The sleeve pipe 8 passes through the center of the anti-blocking net 7 and is fixedly connected to the anti-blocking net 7. The end of the telescopic rod 9 is fixedly connected to the inner wall of the sleeve pipe 8 near the suction pump 3. The other end of the telescopic rod 9 is fixedly connected to the end of the ejection slide rod 10. The other end of the ejection slide rod 10 is fixedly connected to the contact plate 12. The end of the return spring 11 is fixedly connected to the inner wall of the sleeve pipe 8 near the suction pump 3. The other end of the return spring 11 is fixedly connected to the end face of the ejection slide rod 10.

[0024] In an embodiment of the present invention, the sleeve 8 is hollow inside, and the ejector slide rod 10, the telescopic rod 9, and the return spring 11 are all disposed within the internal cavity of the sleeve 8. Simultaneously, a through hole with a diameter matching the outer diameter of the ejector slide rod 10 is provided at the center of the end of the sleeve 8 furthest from the suction pump 3, and the ejector slide rod 10 is slidably mounted within this through hole, allowing it to slide along the hole. Furthermore, the return spring 11 is sleeved on the outside of the telescopic rod 9, so that the telescopic rod 9 can guide and restrict the deformation direction of the return spring 11. Specifically, when the return spring 11 is compressed or stretched, the telescopic rod 9 restricts the return spring 11 so that it can only move within the water... The deformation occurs in the horizontal direction, and it cannot deflect in the vertical direction under its own weight or when squeezed. This ensures that the return spring 11 can always provide a stable transmission effect for the ejector slide rod 10. Furthermore, the outer surface of the contact plate 12 away from the sleeve pipe 8 is set as a hemispherical surface. This ensures that the contact plate 12 can abut against the throttling plug 6 without affecting the normal flow of the heat transfer oil. Moreover, the hemispherical setting prevents the contact plate 12 from causing excessive compression on the end of the throttling plug 6, which would lead to excessive deformation of the throttling plug 6 and prevent the throttling plug 6 from providing a good throttling and blocking effect for the spiral heat exchange tube 5.

[0025] In addition, to prevent excessive suction generated during the operation of the suction pump 3 from causing the throttling plug 6 to excessively squeeze the contact plate 12 and thus causing the throttling plug 6 to break, an auxiliary abutment component is provided inside the sleeve pipe 8. The auxiliary abutment component includes a fixed slide rod 13. The fixed slide rod 13 is fixedly connected to the inner surface of the through hole opened at the end of the sleeve pipe 8 away from the suction pump 3. The end of the fixed slide rod 13 is hinged to the end of the hinged slide rod 14. The other end of the hinged slide rod 14 is fixedly connected to an abutment ball 15.

[0026] In this embodiment of the invention, four sets of abutting components are provided, and the four sets of abutting components are evenly distributed in a circular array around the center of the sleeve 8. This allows them to provide a good auxiliary abutting effect around the contact plate 12, improving the protective effect of the abutting components on the flow-stopping plug 6. Simultaneously, a groove adapted to the fixed slide rod 13 is provided on the arc-shaped outer wall of the ejector slide rod 10. This allows the fixed slide rod 13 to limit the ejector slide rod 10 as it slides along the inner wall of the sleeve 8, preventing deflection and ensuring the stable protection of the flow-stopping plug 6 by the contact plate 12. Furthermore, a width equal to the width of the hinged slide rod 14 is provided on the arc-shaped outer wall of the contact plate 12. The sliding groove is adapted to the degree of the sliding groove, and the inner surface of the sliding groove is provided with a vertically arranged limiting groove. Specifically, the side wall of the hinged sliding rod 14 is provided with a guide rod adapted to the limiting groove, so that when the hinged sliding rod 14 is relatively displaced with the contact plate 12, it can deflect around the hinge point between the hinged sliding rod 14 and the fixed sliding rod 13 as the axis of rotation, so that the abutting ball 15 moves to the left relative to the contact plate 12 and at the same time moves away from the center of the contact plate 12, thereby expanding the area enclosed by the contact plate 12 and the abutting ball 15, thereby increasing the force point of the throttling plug 6, improving the blocking protection effect of the throttling plug 6, and preventing it from being damaged, which would affect the subsequent protection effect of the spiral heat exchange tube 5.

[0027] In this invention, during use, after the reaction in the reactor body 2 on the left side of the outer casing 1 is completed, the suction pump 3 is activated. This allows the heat transfer oil in the spiral heat exchange tube 5 located on the outer side of the reactor body 2 on the left side of the outer casing 1 to be output through the connecting pipe 4 to the spiral heat exchange tube 5 located on the outer side of the reactor body 2 on the right side of the outer casing 1. At the same time, another suction pump 3 is used to extract the cooled heat transfer oil from the spiral heat exchange tube 5 located on the outer side of the reactor body 2 on the right side of the outer casing 1, thereby achieving the exchange of heat transfer oil between the left and right spiral heat exchange tubes 5 inside the outer casing 1. This allows the heat from the reactor body 2 after the reaction to be used to preheat the reactor body 2 before the operation, reducing energy consumption. This method allows for a faster and more effective transfer of heat from one reactor to another, achieving thermal energy conversion. Furthermore, this method can be achieved without the need for a separate heat exchanger, effectively preventing high-viscosity materials that may be used in the reactor from clogging the heat exchanger and hindering effective heat exchange. Specifically, to prevent the throttling plug 6 from completely sealing the anti-blocking mesh 7 when the suction pump 3 is started, an ejector assembly is provided. This assembly, in conjunction with the spring force of the return spring 11, allows the ejector slide rod 10 to engage with the hemispherical contact plate 12 on the right side to provide ejection protection for the throttling plug 6. This prevents it from sliding out of the spiral heat exchange tube 5 and blocking the connecting pipe 4, thus hindering efficient suction and repositioning of the heat transfer oil and affecting the normal operation of the device. Simultaneously, to prevent excessive suction generated during the operation of the suction pump 3... The force causes the throttling plug 6 to be squeezed by the contact plate 12. Through the abutment component, the fixed slide rod 13 and the hinge slide rod 14 move on the arc-shaped outer wall of the contact plate 12, so that the abutment ball 15 moves to the left relative to the contact plate 12 and at the same time moves away from the center of the contact plate 12, thereby expanding the area enclosed by the contact plate 12 and the abutment ball 15, thereby increasing the force points of the throttling plug 6, improving the blocking and protection effect of the throttling plug 6, and preventing it from being damaged, which would affect the subsequent protection effect of the spiral heat exchange tube 5.

[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
