Description

Technical Field

[0001] The present invention relates to the field of welding technology, in particular to an industrial product separation system based on the pyrolysis and vaporization principle. Background Art

[0002] In existing industrial production processes, such as chemical production or sewage treatment processes, especially chemical production, in addition to generating sludge pollution sources, some extremely dangerous chemical solvent pollutants or mixtures of the two are also generated. In the field of environmental protection, environmentally friendly and effective treatment of chemical pollutants is a major issue. Most of the existing sludge pollutants exist in the form of solid-liquid mixtures. How to effectively separate the solid-liquid mixed sludge pollutants is one of the technical problems that need to be solved urgently.

[0003] Since the composition of solid-liquid mixed sludge pollutants is complex, there are some difficulties in its treatment. For example, in addition to free liquid, flocculent solid sludge pollutants also contain interstitial solution, surface adsorption solution and chemical binding solution. The current process equipment cannot effectively remove the interstitial solution, surface adsorption solution and chemical binding solution. The current treatment process for sludge pollutants usually adopts the anaerobic digestion treatment method of sludge. This method mainly uses facultative bacteria and anaerobic bacteria to decompose organic matter in the sludge into carbon dioxide, methane or water, etc., so that the sludge is stabilized. Although this method can effectively treat sludge, it has the following problems: (1) It is suitable for large sludge treatment plants, but not for some small sludge treatment plants. (1) The cost of using the treatment unit is high and the area occupied is large; (2) It needs to be combined with other processes to give full play to its advantages, that is, the process of use is complicated; (3) It requires the additional production of anaerobic bacteria and facultative bacteria, which increases the cost of use. At the same time, the current chemical solvent pollutants such as benzene, alcohols, ethers and other chemical solvents, some of their liquids or solvents have toxic, harmful, flammable and explosive properties. After completing various production tasks and mixing, their tails become harmful sources of danger. If they are not handled properly, they will cause great harm to the human body, the environment and production safety. Based on the analysis of the above problems, this application designs an industrial product separation system based on the principle of pyrolysis and vaporization to achieve effective separation and recovery of products from existing chemical production processes.

[0017] Compared with the prior art, the advantages of the industrial product separation system based on the pyrolysis vaporization principle in this application are:

[0018] (1) The pear-shaped drum reactor 1 is used as a reaction vessel. By rotating and heating the pear-shaped drum reactor 1, not only can the processing efficiency of the product placed inside the pear-shaped drum reactor 1 be improved, but also the floor space occupied can be reduced. That is, the separation system in the present application has a simple process and low operating cost, and can be applied to various large and small industrial product processing units (for large industrial product processing units, multiple groups of pear-shaped drum reactors 1 can be used);

[0019] (2) The diameter of the material inlet and outlet of the pear-shaped drum reactor 1 can be controlled to be small, which is convenient for docking with the sealing mechanism to form an integrated follow-up sealed chamber. At the same time, the vacuum pipeline is sealed and connected to the pear-shaped drum reactor 1. In this way, not only can the separation efficiency of solid-liquid or liquid-liquid products be accelerated, but also the sealed recovery of high-risk harmful substances can be achieved, avoiding the leakage of harmful products that pose a great threat to the environment, human body and production;

[0020] (3) The reactor is set to be pear-shaped and the pear-shaped drum reactor 1 is tilted (the product is not easy to overflow from the opening 3 after the tilting). In this way, not only the product storage space is increased, but also the product heating uniformity is improved. At the same time, because the bottom of the reactor is conical, the phenomenon of material piling and top material at the bottom of the reactor caused by unidirectional rolling can be avoided, which effectively improves the material drop difference and avoids the problem of caking.

[0021] (4) The products are separated and liquefied for recovery using the principle of pyrolysis and vaporization. Compared with the existing anaerobic digestion treatment method (microbial decomposition), the original recovery and recycling of the products are achieved. This not only improves the utilization efficiency of the recycled materials, but also reduces the processing costs.

[0022] (5) High-risk industrial products are vaporized and recovered in liquefied form, which reduces the pollution and threat of high-risk products to the environment and production, and improves the safety of high-risk product treatment.

[0023] (6) Since the boiling point of each substance is different, the pyrolysis and vaporization of different components can be achieved by adjusting the temperature of the heat transfer medium, and then the liquefaction and recovery of different components can be achieved, which can also realize the classified recovery of multiple types of liquid substances.

Figure 1 The system comprises a product separation device and a vacuum line, wherein the product separation device comprises a pear-shaped drum reactor 1 and a heat preservation cover 2, see Figure 2-3The pear-shaped drum reactor 1 is tilted and has an opening 3 (product inlet and outlet) at one relatively high end. A connecting seat 5 for connecting a drive motor 7 is provided at the other end opposite to the opening 3. In order to facilitate the positioning and guidance of the product discharged from the opening 3, a guide component 44 is preferably provided at the lower end of the opening 3. The guide component 44 includes a funnel and a guide groove. The funnel is arranged at the edge of the lower end of the opening 3, and the guide groove is arranged at the discharge end of the funnel. In this embodiment, the cylinder of the pear-shaped drum reactor 1 is formed by a multi-segment splicing method and a squirrel cage assembly process. The diameter of the cylinder of the pear-shaped drum is larger in the middle, and the tapered parts at both ends are shorter. The opening 3 is set At the cone position at one end, the connecting seat 5 is arranged at the cone position at the other end, and the shape of the cone close to one end of the connecting seat 5 is best close to a spherical shape, which not only increases the space for holding the product, but also increases the uniformity of heating the product; the heat preservation cover 2 is arranged on the periphery of the pear-shaped drum reactor 1, and there is a gap between the inner wall of the heat preservation cover 2 and the outer wall of the pear-shaped drum reactor 1 and constitutes a heating chamber, and the pear-shaped drum reactor 1 can rotate in the heating chamber under the drive of the driving motor 7. In this embodiment, the specific structure of the heat preservation cover 2 arranged on the periphery of the pear-shaped drum reactor 1 includes: the heat preservation cover 2 is arranged on the periphery of the pear-shaped drum reactor 1 The outside, that is, the heat preservation cover 2 wraps all parts of the pear-shaped roller reactor 1 except the opening 3 and the drive motor 7. Two groups of support seats 37 are provided in the heat preservation cover 2. The outer surfaces of the two groups of support seats 37 are provided with raceways. The two groups of support seats 37 are respectively arranged on the side of the pear-shaped roller reactor 1 close to the opening 3 and the side close to the connecting seat 5 or at the connecting seat 5. The height of the support seat 37 on the side of the opening 3 is greater than that of the other group (to achieve the inclined setting of the pear-shaped roller), and the pear-shaped roller reactor 1 can rotate relative to the raceway on the support seat 37; in this embodiment, the advantage of setting the height of the support seat 37 on the side of the opening 3 to the highest The invention is that: with the opening 3 as the reference front end, a high front and low back installation method is adopted to maximize the loading space in the pear-shaped drum reactor 1 (the opening 3 end is set higher and the product is not easy to leak out), and at the same time, combined with the pear-shaped structure of the pear-shaped drum reactor 1 itself (the middle diameter is larger and the cones at both ends are shorter) and the installation structure, the maximum area of the product in the drum can be evenly heated, so as to achieve the best solid-liquid and liquid-liquid separation effect; in this embodiment, the connecting seat 5 is a conical structure, and the top of the cone of the connecting seat 5 is preferably arranged on the connection side with the drive motor 7. The connecting seat 5 with the conical structure can reduce or reduce the backward thrust given to the drive motor 7 by the pear-shaped drum reactor 1.

[0054] The heat preservation cover 2 is provided with a sealing door mechanism that is sealed and docked with the opening 3 on the pear-shaped drum reactor 1. The sealing door mechanism can be sealed and connected with the opening 3 of the pear-shaped drum reactor 1 and connect the pear-shaped drum reactor 1 with the vacuum pipeline. In this embodiment, the sealing door mechanism includes a sealing door 8, a sealing door telescopic assembly 10 and a sealing door support assembly 16. Figure 5-6, a pipe 9 is connected to the sealing door 8 and passes through it, and the sealing door 8 is fixed to one end of the sealing door telescopic assembly 10, which includes an outer bracket 11, an inner bracket 13 and a telescopic push rod A15. In this embodiment, the inner and outer brackets 11 are a prism structure or a frame structure with openings 3 at both ends. When it is a frame structure, in order to enhance the stability and firmness of the inner and outer brackets 11, it is preferred to add cross-type reinforcing ribs on at least two sides of the frame. The inner bracket 13 is arranged inside the outer bracket 11 and can be telescopically moved relative to the outer bracket 11 under the push of the telescopic push rod A15 to achieve a tight covering of the sealing door 8 and the opening 3 of the pear-shaped drum reactor 1. In this embodiment, it is preferred that slide grooves 12 are provided on the opposite sides of the outer bracket 11, and slide rails 14 corresponding to the slide grooves 12 are provided on the opposite sides of the inner bracket 13. The inner and outer brackets 11 move relative to each other through the slide grooves 12 and the slide rails 14. Figure 7-8 In this embodiment, the telescopic push rod A15 can be a hydraulic cylinder, an electric push rod or a pneumatic push rod. In this embodiment, a hydraulic cylinder is preferably used. In order to prevent the pear-shaped drum reactor 1 from affecting the vacuum pipeline during rotation, a rotating sleeve assembly 23 is fixed in the inner bracket 13 in this embodiment. The rotating sleeve assembly 23 includes an outer sleeve 24 and an inner sleeve 25. The inner sleeve 25 is sleeved in the outer sleeve 24 and can rotate relative to the outer sleeve 24. The outer sleeve 24 is fixed on the inner bracket 13. The pipe 9 on the sealing door 8 is connected to the inner sleeve 25 and is arranged opposite to the air inlet end of the vacuum pipeline (in order to avoid friction, it is preferred that the pipe 9 port and the air inlet port are non-contact relative to each other). The air inlet end of the vacuum pipeline is connected to the outer sleeve 24. The sleeve 24 is fixedly connected. In this embodiment, the specific structure of the outer sleeve 24 and the inner sleeve 25 includes: the outer sleeve 24 is a cylindrical structure composed of two semicircular hoop plates (the hoop plates are connected by bolts), and a pin 243 (multiple or multiple rows or multiple columns) is provided inside one end of the cylindrical structure, that is, a pin 243 is provided on the inner surface of one end of the hoop plate. In this embodiment, the inner surfaces of the two ends of the hoop plate are preferably provided with convex fasteners, that is, the hoop plate is a semicircular structure that is thick at both ends and thin in the middle. The hoop plate with this structure is convenient for sealing connection with the pipe 9 and the vacuum pipeline. The inner sleeve 25 is an annular structure composed of multiple groups of tooth rollers 251. The teeth 35 on the multiple groups of tooth rollers 251 are meshed with each other. Figure 9-12, the outer tube wall of the end of the pipe 9 on the sealing door 8 is provided with teeth 35 meshing with the tooth roller 251, and the vacuum pipeline is directly connected to the outer sleeve 24 or indirectly connected. In this embodiment, when directly connected and the tooth roller 251 is long (the length of the tooth roller 251 is greater than or equal to two-thirds of the inner cavity length of the outer sleeve 24), the outer tube wall of the air inlet pipe of the vacuum pipeline is provided with teeth 35 meshing with the tooth roller 251 and a pin hole 36 connected to the outer sleeve 24. When indirectly connected and the tooth roller 251 is long, the outer sleeve 24 and the vacuum pipeline are connected through a transfer pipe 3. 1 connection, the outer tube wall of one end of the transfer tube 31 is provided with teeth 35 meshing with the tooth roller 251 and a pin hole 36 connected to the outer sleeve 24. In this embodiment, since the gas transmission pipeline 30 on the vacuum pipeline is mostly made of a flexible hose, it is preferred that the outer sleeve 24 and the vacuum pipeline be connected through the transfer tube 31 for ease of connection. When in use, the teeth 35 on the pipe 9 are meshed with the tooth roller 251, and the teeth 35 on the transfer tube 31 are meshed with the tooth roller 251. At the same time, the pin hole 36 on the transfer tube 31 is connected to the pin 243 on the outer sleeve 24. Figure 13-15 When the driving motor 7 drives the pear-shaped roller reactor 1 to rotate, since the sealing door 8 on the sealing door mechanism is sealed and fixedly connected to the pear-shaped roller reactor 1, the pipe 9 connected to the sealing door 8 will rotate relative to the toothed roller 251 (the toothed roller 251 will rotate relative to the outer sleeve 24 under the drive of the pipe 9). At the same time, since the outer sleeve 24 is fixed on the inner frame and the transfer pipe 31 is fixedly connected to the outer sleeve 24 through the pin 243 and the pin hole 36, the vacuum pipeline will be in a static state. In this embodiment, the toothed roller 251 can not only realize the non-contact docking of the pipe 9 and the transfer pipe 31, but also have a pulling effect on the pipe 9 and the transfer pipe 31 to prevent the vacuum pipeline connected to the transfer pipe 31 from falling off. At the same time, the toothed roller 251 and the pin 243 can realize the pipe 9 and the transfer pipe 31. The setting of two states, dynamic and static, avoids the influence of the rotation of the pipe 9 on the vacuum pipeline, or; in this embodiment, when directly connected and the length of the tooth roller 251 is short (the length of the tooth roller 251 is less than or equal to half of the inner cavity of the outer sleeve 24), the outer tube wall of the air inlet pipe of the vacuum pipeline is only provided with a pin hole 36 connected to the outer sleeve 24. When indirectly connected and the length of the tooth roller 251 is short, the outer sleeve 24 and the vacuum pipeline are connected through a transfer tube 31, and the outer tube wall of one end of the transfer tube 31 is only provided with a pin hole 36 connected to the outer sleeve 24. In this embodiment, the outer sleeve 24 and the vacuum pipeline are preferably connected through a transfer tube 31. When in use, the teeth 35 on the pipe 9 are engaged with the tooth roller 251, and the pin hole 36 on the transfer tube 31 is connected to the pin column 243 on the outer sleeve 24. See Figure 16-17When the driving motor 7 drives the pear-shaped roller reactor 1 to rotate, since the sealing door 8 on the sealing door mechanism is sealed and fixedly connected to the pear-shaped roller reactor 1, the pipe 9 connected to the sealing door 8 will rotate relative to the toothed roller 251 (the toothed roller 251 will rotate relative to the outer sleeve 24 under the drive of the pipe 9). At the same time, since the outer sleeve 24 is fixed on the inner frame and the transfer pipe 31 is fixedly connected to the outer sleeve 24 through the pin 243 and the pin hole 36, the vacuum pipeline will be in a static state. In this embodiment, the pipe 9 can be fixed by the toothed roller 251, and the transfer pipe 31 can be fixed by the pin 243 on the outer sleeve 24. Since the toothed roller 251 is arranged in the outer sleeve 24 and the outer sleeve 24 is fixed to the inner frame The outer sleeve 24 and the toothed roller 251 can be used to pull the pipe 9 and the transfer pipe 31 to prevent the vacuum line connected to the transfer pipe 31 from falling off. At the same time, the toothed roller 251 and the pin 243 can be used to set the pipe 9 and the transfer pipe 31 in two states, one dynamic and one static, to avoid the influence of the rotation of the pipe 9 on the vacuum line. In this embodiment, two groups of door sealing support assemblies 16 are included. The door sealing support assembly 16 includes a bracket 17 and a telescopic push rod B21. The bracket 17 includes a fixed arm 18, a cantilever 19 and an extension arm 20. The fixed arm 18 and the extension arm 20 are connected by the cantilever 19, that is, the bracket 17 forms a "J"-shaped structure. The fixed arms 18 of the two groups of door sealing support assemblies 16 and the telescopic push rod B21 are connected. The free ends of 1 are respectively hinged on the two side surfaces of the heat preservation cover 2, and the telescopic end of the telescopic push rod B21 is hinged at the middle position of the fixed arm 18 or one end close to the cantilever 19. The outer frame in the door telescopic assembly 10 is fixed on the extension arm 20. The telescopic push rod B21 pushes the bracket 17 to move, which can drive the door 8 to make a pitching motion with an arc trajectory (the hinge point of the fixed arm 18 is the center of the circle) so that it can be aligned with or moved away from the opening 3 on the pear-shaped drum reactor 1. In this embodiment, when the door 8 is moved away from the opening 3 by using the bracket 17, an outward-retracting movement trajectory is executed, which will avoid collision or scratching of the sealing surface of the door 8 during the process of introducing industrial products. In this embodiment, in order to achieve precise alignment, it is preferably provided with The limiter includes a limit switch 22, one end of which is connected to the fixed arm 18 and the other end is fixed to the heat preservation cover 2. When the telescopic push rod B21 pushes the bracket 17 to move to a specific position (the position where the sealing door 8 is aligned with the opening 3), the limit switch 22 is closed and the telescopic push rod B21 is controlled to stop working through the limiter. The advantage of setting the bracket 17 to a "J"-shaped structure in this embodiment is that it is conducive to the downward shift of the overall center of gravity of the sealing door mechanism and improves the stability of the movement of the bracket 17. In order to improve the load-bearing capacity of the bracket 17, it is preferably made of high-strength steel. At the same time, a stress reinforcement block 45 is provided at the corner where the fixed arm 18, the cantilever 19 and the extension arm 20 are connected;In this embodiment, the telescopic push rod B21 can be a hydraulic cylinder, an electric push rod or a pneumatic push rod. In this embodiment, a hydraulic cylinder is preferred. When in use, the telescopic push rod B21 will rotate the push-pull bracket 17 about the hinge point of the fixed bracket 17 during the telescopic process, wherein the movement trajectory of the sealing door 8 and the sealing door telescopic assembly 10 will be arc-shaped, that is, when in use, the sealing door 8 and the sealing door telescopic assembly 10 will have a certain displacement relative to the horizontal position. In this embodiment, the gas pipeline 30 preferably connected to the transfer tube 31 is a flexible pipeline 9, and its length has a certain telescopic space, so that This prevents the movement of the sealing door 8 and the door-sealing telescopic assembly 10 from affecting the vacuum pumping line, particularly addressing the problem of prolonged tension between the pipe 9 or the transfer tube 31 and the rotating sleeve. In this embodiment, the center of gravity of the door-sealing mechanism is primarily on the sealing door 8 and the door-sealing telescopic assembly 10. Therefore, in addition to increasing the load-bearing capacity (material and thickness) of the bracket 17 itself, the bracket 17 in the door-sealing support assembly 16 can also be supported by multiple telescopic push rods B21 (not shown) as needed. This provides support and reinforcement for the bracket 17, preventing it from tilting or being damaged.

[0055] In this embodiment, the vacuum pipeline includes at least one group of sealed storage tanks 26, negative pressure vacuum pumps 27, condensers 28 and control valves 29. The sealed storage tanks 26, negative pressure vacuum pumps 27, control valves 29 and condensers 28 are all connected through a gas pipeline 30. The vacuum pipeline can be used to vacuum the pear-shaped drum reactor 1 and liquefy and recover the vapor phase products in the pear-shaped drum reactor 1; in this embodiment, the negative pressure vacuum pump 27 is provided with an air pressure sensor 38, and the air pressure sensor 38 can be used to indirectly monitor the air pressure signal in the pear-shaped drum reactor 1.

[0056] Furthermore, in this embodiment, in order to achieve a sealed connection between the rotating sleeve assembly 23 and the pipeline 9 and the transfer tube 31, and to prevent gas leakage from the connection gap, it is preferred that a sealing gasket 244 is provided on the inner wall of both ends of the outer sleeve 24. The sealing gasket 244 can be in close contact with the outer wall of the pipeline 9 on the sealing door 8 and the outer wall of the transfer tube 31 to achieve a sealed connection between the pipeline 9 on the sealing door 8 and the vacuum pipeline.

[0057] Furthermore, in this embodiment, a connecting arm 241 is provided on the outer sleeve 24 of the rotating sleeve assembly 23. The connecting arm 241 is arranged on both sides of the outer sleeve 24 along its length direction. The two connecting arms 241 are connected by a connecting plate. The outer sleeve 24 is fixedly connected to the inner bracket 13 through the connecting arm 241 and the connecting plate. The connecting arm 241 is used to achieve a firm connection of the outer sleeve 24 in the inner bracket 13.

[0058] Furthermore, in this embodiment, the heating device for heating the pear-shaped drum reactor 1 includes an electric heating component or a medium circulation heating pipeline. Of course, under permitted and reasonable circumstances, open flame can also be used for heating (for safety reasons, it can be a heating method but it is not recommended). When it is an electric heating component, the electric heating component includes an electric heating pipe, which is arranged at the bottom of the inner cavity of the heat preservation cover 2, and the heat emitted by the electric heating pipe is used to realize the pyrolysis and vaporization of the product in the pear-shaped drum reactor 1; when it is a medium circulation heating pipeline, the circulation of the medium circulation heating pipeline is The annular medium is preferably water. Of course, it can also be gas or liquid such as heat transfer oil or steam that can circulate in the pipeline 9. In this embodiment, the preferred heating device is a medium circulation heating pipeline, which includes a medium circulation pipeline 39, a circulation pump 40, a reflux box 41 and a control valve 29. The medium circulation pipeline 39 includes a water inlet pipeline and a water outlet pipeline, wherein the water inlet of the water inlet pipeline is connected to the water outlet end of the circulation pump 40, the drain outlet of the water inlet pipeline is preferably set at the top of the insulation cover 2, and the water inlet of the water outlet pipeline is preferably set near the bottom of the insulation cover 2. The drain outlet is connected to the inlet of the return box 41, and the circulation pump 40 is arranged between the return box 41 and the water inlet pipeline. The control valve 29 is arranged on the medium circulation pipeline 39 as a switching element for the circulation of the heating medium. In this embodiment, the number of control valves 29 is not specifically limited, and it depends on the actual layout structure of the medium circulation pipeline 39; a temperature sensor 42 is provided in the return box 41, and the temperature sensor 42 can be used to monitor the water temperature in the return box 41 in real time. In this embodiment, the return box 41 has its own heating component, or a heater 43 is added to the medium circulation pipeline to return the water. Box 41 is only used as a water storage unit. In order to save energy, the medium can also be used to recycle waste water, waste gas and other heat sources generated by other heat sources. In this embodiment, when the medium is recovered waste heat, it is preferred to set a cooling pipeline in the medium circulation heating pipeline. The cooling pipeline can use air cooling or water cooling to achieve readjustment of the temperature of the heat transfer medium. In this embodiment, the cooling pipeline preferably includes a condenser 28, a cooling box 32 and a coolant circulation pipeline 33. The cooling liquid is stored in the cooling box 32, and the coolant flows in the coolant circulation pipeline 33 and passes through the condenser 28 to adjust the temperature of the heat transfer medium.

[0059] In this embodiment, the control valve 29 can be a solenoid valve, an electric valve, a pneumatic valve or a manual-automatic valve. In this embodiment, a pneumatic valve is preferred.

[0060] When the present embodiment is in use, the industrial product is first put into the opening 3 of the pear-shaped drum, and then the hydraulic cylinder B in the door sealing support assembly 16 drives the bracket 17 to move, thereby driving the door sealing 8 and the door sealing telescopic assembly 10 to do a pitching movement and, under the action of the limiter, the door sealing 8 is aligned with the opening 3 of the pear-shaped drum. Then, the hydraulic cylinder A in the door sealing telescopic assembly 10 pushes the inner bracket 13 to move toward the side of the opening 3 relative to the outer bracket 11 until the door sealing 8 and the opening 3 are sealed and docked, and the hydraulic cylinder A is locked to keep it in the current state (it has a backlog effect on the door sealing 8, realizing the sealed docking of the door sealing 8 and the opening 3). The above steps complete the addition of the product and the sealing operation of the pear-shaped drum reactor 1. Then, the negative pressure vacuum pump 27 in the vacuum line is started to vacuum the pear-shaped drum reactor 1. Finally, the circulation pump 40 in the medium circulation heating line is started to input hot water (the temperature is constant, specifically determined according to the boiling point of the substance to be recovered. For example, if the boiling point of water is 100°C, the hot water can be heated to 100°C. When the reactor is used for the first time, the hot water temperature can be slightly higher; if the boiling point of ethanol is 78°C, the hot water can be heated to 78°C) into the heating chamber formed by the heat preservation cover 2 and the pear-shaped drum reactor 1. In this embodiment, The amount of hot water in the heating chamber is preferably not more than the height of the connecting seat 5 of the pear-shaped drum reactor 1. At the same time, the driving motor 7 is started to drive the pear-shaped drum reactor 1 to rotate in the heating chamber. Since the hot water flows from the upper end to the lower end of the pear-shaped drum reactor 1, the shell of the pear-shaped drum reactor 1 will be preheated in this process, and then the position near the bottom of the pear-shaped drum reactor 1 will be immersed in the hot water accumulated in the heating chamber for directionally heating. During the rotation of the pear-shaped drum reactor 1, some components in the product will vaporize at this temperature. After a certain reaction time, the negative pressure vacuum in the vacuum pipeline will be started. The pump 27 extracts the gaseous product generated inside the pear-shaped drum reactor 1 and liquefies it through the condenser 28 and then stores it in the designated sealed storage tank 26. At this time, the recovery of one component in the industrial product is completed. If other components need to be recovered, the hot water in the heating chamber is returned to the reflux tank 41 through the outlet pipe and the hot water is heated or cooled as needed (preferably, for the convenience of operation, the boiling points of each substance or component can be determined from low to high, and finally the temperature of the hot water is gradually increased from low to high, so that each substance / component can be liquefied and recovered separately). Then, the above-mentioned pyrolysis, vaporization and liquefaction recovery operations are performed, see Figure 18 , which is a control principle diagram of the industrial product separation system provided in this embodiment; in this embodiment, after completing the pyrolysis, vaporization and liquefaction recovery operations of all components, the residue remaining inside the pear-shaped drum reactor 1 can be removed from the reactor cavity and cleaned by means of an external extraction pipe 9 or an excavation mechanism.

[0061] In this embodiment, multiple product separation devices can be connected in parallel as needed. These multiple product separation devices can be used to heat media at different temperatures to simultaneously recover different substances / components. Of course, multiple industrial product separation systems can also be selected as needed.

[0062] In summary, the product separation device in this embodiment has a simple process, low operating cost and a wide range of uses. The product separation device in this embodiment can not only accelerate the separation efficiency of solid-liquid or liquid-liquid products, but also realize the closed recovery of high-risk harmful substances, avoid the leakage of harmful products and cause great threats to the environment, human body and production, and improve the safety of high-risk product processing; at the same time, this embodiment sets the reactor into a pear shape and tilts the pear-shaped drum reactor 1 (after the tilt is set, the product is not easy to overflow from the opening 3). In this way, not only the product storage space is increased, but also the heating uniformity of the product is improved, and the pyrolysis and vaporization efficiency of each component in the product is increased. Since each substance has a different boiling point, the pyrolysis and vaporization of different components can be achieved by adjusting the temperature of the heat transfer medium, and then the liquefaction recovery of different substances can be achieved, which can also realize the classified recovery of multiple varieties of liquid phase substances. Compared with the existing ones, this embodiment separates and liquefies the products using the principle of pyrolysis and vaporization, realizing the original recovery and recycling of each component in the product. In this way, not only the utilization efficiency of the recyclables is improved, but also the processing cost is reduced.

[0063] In this embodiment, the separation system can also be applied to solid-liquid or liquid-liquid separation in other fields as needed.

[0064] Example 2: Compared with Example 1, the difference of this embodiment is that the inner and outer sleeves 24 in the rotating sleeve assembly 23 are both cylindrical structures and a ball 242 is provided between the inner and outer sleeves 24. Under the action of the ball 242, the inner and outer sleeves 24 can rotate relative to each other, that is, the rotating sleeve assembly 23 is a bearing structure, see Figure 19 The pipe 9 on the sealing door 8 and the inner sleeve 25 can be consolidated by welding or flanges, and the vacuum pipeline is directly or indirectly connected to the outer sleeve 24. However, when directly connected, the air inlet end of the vacuum pipeline is fixedly connected to the outer sleeve 24 by welding or flanges; when indirectly connected, the outer sleeve 24 and the vacuum pipeline are connected by a transfer tube 31, and one end of the transfer tube 31 is fixedly connected by welding or flanges; in this embodiment, the outer sleeve 24 and the vacuum pipeline are preferably connected by a transfer tube 31.

[0065] Example 3: Compared with Example 1 or 2, the difference of this embodiment is that the cross section of the sealing door 8 is a trumpet-shaped structure, or the cross section of the sealing door 8 is a "bow"-shaped structure, and a card slot 81 is provided on the sealing door 8. The opening 3 of the pear-shaped drum reactor 1 is provided with a protrusion 4 with a sealing gasket 41 that can be inserted into the card slot 81. Figure 20-22When in use, the sealing door 8 is brought into contact with the opening 3 under the push of the sealing door telescopic assembly 10 and the protrusion 4 is snapped into the card slot 81 to achieve efficient sealing;

[0066] Alternatively, the sealing door 8 is provided with a protrusion 4, the inner ring of which is embedded with a sealing gasket 41, which can contact the outer periphery of the sealing door 8, see Figure 23-25 When in use, the sealing door 8 is pushed toward the end of the opening 3 under the push of the sealing door telescopic assembly 10, and the outer periphery of the sealing door 8 is in close contact with the sealing gasket 41 on the inner circle of the protrusion 4 to achieve efficient sealing.

[0067] Example 4: Compared with Example 1, 2 or 3, the difference of this embodiment is that, in order to facilitate the removal of the residue after the reaction inside the pear-shaped drum reactor 1 from the inner cavity of the reactor, a spiral mechanism 34 is preferably fixed in the inner cavity of the pear-shaped drum reactor 1. The spiral mechanism 34 is in the shape of a logarithmic spiral curve or an Archimedean spiral line. In this embodiment, it is preferably in the shape of a logarithmic spiral curve, see Figure 26 When the driving motor 7 drives the pear-shaped drum reactor 1 in forward rotation, the spiral mechanism 34 rotates with the reactor and stirs the product in the reactor cavity. When the driving motor 7 drives the pear-shaped drum reactor 1 in reverse rotation, the spiral mechanism 34 rotates with the reactor and pushes the product out of the opening 3. In this embodiment, by setting and controlling the rotation direction of the spiral mechanism 34, not only can the product be stirred so that it is evenly heated to improve the pyrolysis and vaporization efficiency, but also the residue (residue) after the reaction can be removed from the reactor, thereby accelerating the treatment efficiency of the residue.

[0068] Example 5: Compared with Example 1, 2, 3 or 4, the difference of this embodiment is that, in order to avoid the problem of pressure increase in the heating chamber when the heat-conducting medium flows in the heating chamber, it is preferred to independently set a heating medium negative pressure recovery pipeline, see Figure 27 The heating medium negative pressure recovery pipeline preferably includes a medium recovery pipeline, a negative pressure vacuum pump 27, a sealed storage tank 26 and a condenser 28. During use, when the air pressure in the heating box reaches a certain value, the negative pressure vacuum pump 27 is started to recover the vaporized medium through the medium recovery pipeline and store it in the sealed storage tank 26 after liquefaction in the condenser 28. This embodiment uses the heating medium negative pressure recovery pipeline to improve the safety of the working environment. In this embodiment, when necessary, the sealed storage tank in the heating medium negative pressure recovery pipeline can be connected to the reflux box 41 in the medium circulation heating pipeline through the circulation pump 40, that is, the recovered medium is recycled.

[0069] In this embodiment, a control valve 29 is preferably provided on the medium recovery pipeline and the pipeline connected to the circulation pump 40. The control valve 29 can be a solenoid valve, an electric valve, a pneumatic valve or a manual-automatic valve. In this embodiment, a pneumatic valve is preferably used.
