Description

Technical Field

[0001] The present invention relates to the technical field of chlorinated paraffin production, and in particular to a high-efficiency chlorinated paraffin production device and method with waste heat utilization function. Background Art

[0002] During the production of chlorinated paraffins, a large amount of reaction heat is generated. In order to maintain a suitable reaction temperature and ensure production safety, it is usually necessary to remove this waste heat.

[0003] Traditional waste heat recovery devices mostly use heat exchange coils for heat exchange. The heat exchange coils are usually designed as single-layer spiral coils or parallel straight tubes. When the coils are in contact with the heat source, gaps inevitably exist between adjacent tubes. The heat source in these gaps cannot directly contact the cooling medium, resulting in uneven temperature distribution on the heat source surface. Some heat cannot be effectively absorbed, resulting in heat energy waste and limiting the overall waste heat recovery efficiency.

[0004] When cooling water continuously flows through the entire heat exchange coil, the phenomenon of "high efficiency at the front end and low efficiency at the back end" will occur, making the average heat exchange efficiency of the system far lower than the theoretical maximum, making it difficult to achieve deep recovery and utilization of waste heat;

[0005] In addition, a simple control strategy of continuous water flow or roughly starting and stopping the water pump based on a single temperature point is often adopted. This method lacks fine-grained regulation of the heat exchange process. Summary of the Invention

[0017] A method for using a chlorinated paraffin high-efficiency production device with waste heat utilization function comprises the following steps:

[0018] S1: Chlorine gas and chlorinated paraffin are introduced into the interior of the reaction cylinder, and the stirring assembly stirs and reacts them. Heat is generated during the reaction, and cooling water enters the interior of the second annular water tank through the water injection pipe and the metal hose. The heat inside the reaction cylinder increases the temperature of the thermal magnetic ring. As the temperature of the thermal magnetic ring gradually increases, it generates magnetism that attracts the permanent magnetic ring. Therefore, under the action of the magnetic attraction between the thermal magnetic ring and the permanent magnetic ring, the thermal magnetic ring is attracted to move toward the carrier ring and compresses the spring. Since the thermal magnetic ring is separated from the interior of the second annular water tank, it will release its obstruction to the second water spray hole on the second annular water tank. Therefore, the cooling water inside the second annular water tank will be sprayed out and sprayed onto the outer wall surface of the reaction cylinder;

[0019] S2: The water sprayed from the second annular water tank not only cools the reaction tube, but also cools the thermal magnetic ring. After the thermal magnetic ring cools down, its own magnetic force disappears. Under the elastic return action of the spring, the thermal magnetic ring returns to the inside of the second annular water tank to block the second water spray hole.

[0020] S3: When the thermal magnetic ring is descending, the linkage moves downward with the spur rack. Under the meshing transmission action of the spur rack and the driving gear, the spur rack descends to drive the main shaft to rotate. Under the longitudinal transmission action of the bevel gear transmission member, the driven shaft rotates with the main shaft, and finally the driven gear rotates. Under the meshing transmission action of the driven gear and the arc-shaped rack, the second annular water tank is driven to rotate. The rotation of the second annular water tank will change the injection angle of the second water spray hole thereon, which is used to make up for the gap and spray blind angle between the two adjacent second water spray holes, thereby improving the comprehensiveness and uniformity of the heat exchange of the reaction cylinder. When the thermal magnetic ring resets upward, it will also drive the second annular water tank to rotate and reset under the transmission action;

[0021] S4: When the cooling water is sprayed out from the first annular water tank, it will directly spray onto the curved surface at the bottom of the reaction tube. Due to the restriction of the cooling water by the deflector, the cooling water does not fall vertically. Instead, it is guided by the inner wall of the deflector and slides along the curved surface at the bottom of the reaction tube. The lowermost heat exchange component will also drive the water blocking ring to release the obstruction of the first water spray hole in the first annular water tank, and the first annular water tank is driven to rotate in conjunction with it.

[0022] S5: Finally, the heated cooling water is discharged to the outside through the return pipe.

[0023] In summary, the present invention has at least one of the following beneficial effects:

[0024] 1. In the present invention, high temperature causes the magnetism of the thermal magnetic ring to attract and decrease the magnetism of the permanent magnetic ring, and removes the obstruction to the second water spray hole on the second annular water tank. The cooling water is sprayed for cooling. After the temperature drops, the magnetism disappears and the second water spray hole is blocked again. The absence of electric drive is not only more stable, but also reduces costs.

[0025] 2. In the present invention, when cooling water is sprayed out from the inside of the first annular water tank, it will be sprayed directly onto the curved surface at the bottom of the reaction tube. Due to the restriction of the cooling water by the deflector, the cooling water is prevented from falling vertically. Instead, it is guided by the inner wall of the deflector and slides along the curved surface at the bottom of the reaction tube, thereby extending and expanding the contact time and contact area between the cooling water and the curved surface at the bottom of the reaction tube, more effectively carrying the heat at the end of the bottom curved surface, and improving the effect of waste heat recovery.

[0026] 3. In the present invention, when the thermal magnetic ring descends, it drives the annular water bin to rotate. The rotation of the annular water bin will change the spray angle of the second water spray hole thereon, which is used to make up for the gap and spray dead angle between two adjacent second water spray holes, thereby improving the comprehensiveness and uniformity of heat exchange of the reaction tube. In addition, the rotation of the second annular water bin is driven by a purely mechanical structure without any electrical equipment, thus avoiding the unsafe conditions in high temperature and humid environments and further reducing the cost of use.

[0027] 4. In the present invention, multiple heat exchange components and a first annular water tank that fits the arc end of the bottom of the reaction tube for cooling are installed on the outer wall of the reaction tube. The segmented cooling and heat exchange design effectively solves the gap problem between adjacent pipes of the traditional single coil, can cover the heat source surface more tightly and comprehensively, maximize the thermal contact area, reduce the ineffective heat dissipation area, ensure that the heat is more fully absorbed, and significantly increase the effective average temperature difference of each section of the heat exchange surface. It overcomes the disadvantages of the traditional method of reduced temperature difference and low efficiency caused by the heating of the cooling water in the latter section, thereby greatly improving the average heat exchange efficiency of the entire system and the total amount of waste heat recovery. In addition, the thermomagnetic magnetic control determines whether to remove the obstruction of the water spray hole, and dynamically adjusts the cooling water cooling and heat exchange according to the real-time temperature, avoiding the energy waste caused by continuous large-flow water supply in the traditional design.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] The embodiment of the present invention discloses a high-efficiency chlorinated paraffin production device and method with waste heat utilization function.

[0039] Example 1

[0040] Reference Figure 1-6 , which is the first embodiment of the present invention, provides a high-efficiency chlorinated paraffin production device and method with waste heat utilization function. This high-efficiency chlorinated paraffin production device with waste heat utilization function includes a heat-insulating sleeve 1 and a support leg 3 welded to the bottom of the heat-insulating sleeve 1. A reaction cylinder 2 is fixed inside the heat-insulating sleeve 1, and the discharge end of the reaction cylinder 2 passes through the interior of the heat-insulating sleeve 1. The feed end of the reaction cylinder 2 is located above the heat-insulating sleeve 1. A cylinder cover 4 is installed on the top of the reaction cylinder 2. Injection pipes 6 are welded to the feed ports on both sides of the top of the cylinder cover 4. A stirring assembly 7 is installed at the center of the circle on the top of the cylinder cover 4, and the stirring end of the stirring assembly 7 is located inside the reaction cylinder 2. A plurality of heat exchange assemblies 8 for exchanging heat with the reaction cylinder 2 are installed vertically and evenly spaced inside the thermal insulation sleeve 1, and the reaction cylinder 2 passes through the inner hole of the heat exchange assembly 8. A rotation drive assembly 9 for driving the heat exchange assembly 8 to rotate is installed on one side of the interior of the thermal insulation sleeve 1 and at a position facing each heat exchange assembly 8. A drainage hole is opened on one side of the bottom of the thermal insulation sleeve 1, and a return pipe 5 is welded to the thermal insulation sleeve 1 facing the drainage hole.

[0041] A first bearing 11 is welded to the bottom of the inner part of the thermal insulation sleeve 1 through a bracket, and a first annular water tank 12 is rotatably installed in the inner hole of the first bearing 11. A circle of first water spray holes 18 is provided on the inner wall surface of the first annular water tank 12, and a water blocking ring 15 is provided in the inner hole of the first annular water tank 12, and the reaction cylinder 2 passes through the inner hole of the water blocking ring 15. A lifting connecting frame 10 is welded between the lifting end of the heat exchange component 8 near the first bearing 11 side and the peripheral surface of the water blocking ring 15, and a rotating connecting frame 14 is welded between the rotating end of the heat exchange component 8 near the first bearing 11 side and the peripheral surface of the first annular water tank 12.

[0042] The heat exchange component 8 includes a second bearing 81 welded to the inside of the thermal insulation sleeve 1 through a bracket, and a second annular water tank 82 is rotatably installed in the inner hole of the second bearing 81. A circle of second water spray holes is provided on the inner wall surface of the second annular water tank 82. The annularly designed second annular water tank 82 sprays water to the reaction cylinder 2 in an annular manner. The sprayed water will slide down along the outer wall of the reaction cylinder 2, and the contact area with the reaction cylinder 2 will be expanded during the sliding process, and heat will be exchanged and absorbed. A thermal magnetic ring 83 is lifted and arranged in the inner hole of the second annular water tank 82, and the reaction cylinder 2 passes through the inner hole of the thermal magnetic ring 83. The thermal magnetic ring 83 is made of nickel-cobalt-manganese-indium alloy. The heat exchange component 8 is made of gold. The heat exchange component 8 also includes a permanent magnetic ring 811 welded to the peripheral surface of the reaction tube 2, and the permanent magnetic ring 811 is arranged directly below the thermal magnetic ring 83. At the same time, the opposite surfaces of the thermal magnetic ring 83 and the permanent magnetic ring 811 are in a magnetic adsorption state. A circle of spring column 812 is installed on the opposite surfaces of the thermal magnetic ring 83 and the permanent magnetic ring 811, and a spring 813 is installed between the two corresponding spring columns 812. A circle of drainage cavity 810 is provided on the peripheral surface of the permanent magnetic ring 811 at equal intervals. The cooling water trapped by the permanent magnetic ring 811 is discharged through the drainage cavity 810 to prevent the cooling water from remaining in the inner hole of the permanent magnetic ring 811 for a long time and contacting the outer wall of the reaction tube 2.

[0043] The high temperature causes the thermal magnetic ring 83 to generate magnetism and the permanent magnetic ring 811 to attract and decrease, and remove the obstruction to the second water spray hole on the second annular water tank 82. The cooling water is sprayed for cooling. After the temperature drops, the magnetism disappears and the second water spray hole is blocked again. The absence of electric drive is not only more stable, but also reduces costs.

[0044] A metal hose 84 is installed at the water inlet of the second annular water tank 82 and the first annular water tank 12, and a water injection pipe 85 is installed at the water inlet of the metal hose 84. The water injection pipe 85 is inserted and installed on the insulation sleeve 1, and the water inlet of the water injection pipe 85 is located outside the insulation sleeve 1.

[0045] The inner wall surface of the thermal magnetic ring 83 is provided with a number of slideways 88 at equal intervals. The internal sliding of the thermal magnetic ring 83 is provided with a guide slide 86, and the guide slide 86 is fixed on the outer wall surface of the thermal insulation sleeve 1. The top of the guide slide 86 is welded with a block 87 for blocking the thermal magnetic ring 83. The thermal magnetic ring 83 is vertically slidably connected with the guide slide 86 through the slide 88 thereon. Under the guidance of the two, the thermal magnetic ring 83 can only be lifted and lowered vertically, ensuring the stability of the thermal magnetic ring 83, and the block 87 limits the maximum height of the thermal magnetic ring 83 to reset upward, ensuring that the thermal magnetic ring 83 effectively blocks the second water spray hole.

[0046] The outer wall of the reaction tube 2 is equipped with multiple heat exchange components 8 and a first annular water tank 12 that fits the arc end of the bottom of the reaction tube 2 for cooling. The segmented cooling and heat exchange design effectively solves the gap problem between adjacent pipes of the traditional single coil, and can cover the heat source surface more tightly and comprehensively, maximize the thermal contact area, reduce the ineffective heat dissipation area, ensure that the heat is more fully absorbed, and significantly increase the effective average temperature difference of each section of the heat exchange surface. It overcomes the disadvantages of the traditional method of reduced temperature difference and low efficiency caused by the heating of the cooling water in the latter section, thereby greatly improving the average heat exchange efficiency and the total amount of waste heat recovery of the entire system. In addition, the thermomagnetic magnetic control determines whether to remove the obstruction of the water spray hole, and dynamically adjusts the cooling water cooling and heat exchange according to the real-time temperature, avoiding the energy waste caused by continuous large-flow water supply in the traditional design.

[0047] The rotation drive assembly 9 includes an arc-shaped rack 91 installed on the outer wall of the second annular water tank 82 and a driven gear 92 meshing with the arc-shaped rack 91 . A linkage assembly for driving the driven gear 92 to rotate is installed at the bottom of the thermal magnetic ring 83 .

[0048] The linkage assembly includes a shaft block 95 and a shaft frame 94 installed on the inner wall of the thermal insulation sleeve 1. The shaft frame 94 is rotatably installed with a driven shaft 93 through a bearing installed thereon, and the driven gear 92 is fixed to the top of the driven shaft 93. The end of the shaft block 95 close to the thermal magnetic ring 83 is rotatably installed with a main shaft 97 through a bearing. A bevel gear transmission member 96 is installed between the driven shaft 93 and the main shaft 97. The bevel gear transmission member 96 consists of two meshing bevel gears. A driving gear 98 is installed on the end of the main shaft 97 away from the shaft block 95, and a straight rack 99 meshing with the driving gear 98 is installed at the bottom of the thermal magnetic ring 83.

[0049] When the thermal magnetic ring 83 is descending, the linkage moves the spur rack 99 downward. Under the meshing transmission action of the spur rack 99 and the driving gear 98, the spur rack 99 descends to drive the main shaft 97 to rotate. Under the longitudinal transmission action of the bevel gear transmission member 96, the driven shaft 93 rotates following the main shaft 97, and finally the driven gear 92 rotates. Under the meshing transmission action of the driven gear 92 and the arc-shaped rack 91, the second annular water tank 82 is driven to rotate.

[0050] When the thermal magnetic ring 83 is reset upward, it will also drive the second annular water tank 82 to rotate and reset under the action of transmission;

[0051] Since the rotation of the second annular water tank 82 will change the spray angle of the second water spray hole thereon, it is used to make up for the gap and spray dead angle between two adjacent second water spray holes, thereby improving the comprehensiveness and uniformity of heat exchange of the reaction tube 2. In addition, the rotation of the second annular water tank 82 is driven by a purely mechanical structure without any electrical equipment, avoiding unsafe conditions in high temperature and humid environments, and further reducing the cost of use.

[0052] Inside the thermal insulation sleeve 1 and below the first bearing 11, there is a flow guide 13 welded through a bracket to wrap the bottom of the reaction cylinder 2. A recovery hole 16 is provided in the middle of the bottom of the flow guide 13 for the discharge end of the reaction cylinder 2 to pass through. A circle of grooves 17 is provided at one end of the flow guide 13 near the first annular water tank 12. The lowest heat exchange component 8 will also simultaneously drive the water blocking ring 15 to release the obstruction of the first water spray hole 18 on the first annular water tank 12, and drive the first annular water tank 12 to rotate in conjunction.

[0053] The stirring assembly 7 includes a driving motor installed on the top of the barrel cover 4, and the driving end of the driving motor is located inside the barrel cover 4. The driving end of the driving motor is equipped with a stirring shaft, and the bottom end of the stirring shaft is located inside the reaction barrel 2. A stirring blade is installed at one end of the stirring shaft located inside the reaction barrel 2.

[0054] When the cooling water is sprayed out from the inside of the first annular water tank 12, it will be sprayed directly onto the curved surface at the bottom of the reaction tube 2. Due to the restriction of the cooling water by the deflector 13, the cooling water is prevented from falling vertically. Instead, it is guided by the inner wall of the deflector 13 and slides along the curved surface at the bottom of the reaction tube 2, extending and expanding the contact time and contact area between the cooling water and the curved surface at the bottom of the reaction tube 2, more effectively carrying the heat at the bottom curved surface end, and improving the effect of waste heat recovery.

[0055] A method for using a chlorinated paraffin high-efficiency production device with waste heat utilization function comprises the following steps:

[0056] S1: Chlorine gas and chlorinated paraffin are introduced into the interior of the reaction cylinder 2, and the stirring assembly 7 stirs and reacts them. Heat is generated during the reaction, and cooling water enters the interior of the second annular water tank 82 through the water injection pipe 85 and the metal hose 84. The heat inside the reaction cylinder 2 will increase the temperature of the thermal magnetic ring 83. When the temperature of the thermal magnetic ring 83 gradually increases, it will generate magnetism that attracts the permanent magnetic ring 811. Therefore, under the action of the magnetic attraction between the thermal magnetic ring 83 and the permanent magnetic ring 811, the thermal magnetic ring 83 is attracted to move toward the carrying ring 89 and compress the spring 813. Since the thermal magnetic ring 83 is separated from the interior of the second annular water tank 82, it will release its obstruction to the second water spray hole on the second annular water tank 82. Therefore, the cooling water inside the second annular water tank 82 will be sprayed out and sprayed onto the outer wall surface of the reaction cylinder 2;

[0057] S2: The water sprayed from the second annular water reservoir 82 not only cools the reaction tube 2, but also cools the thermal magnetic ring 83. After the thermal magnetic ring 83 cools down, its own magnetic force disappears. Under the elastic restoring action of the spring 813, the thermal magnetic ring 83 returns to the inside of the second annular water reservoir 82 to block the second water spray hole.

[0058] S3: When the thermal magnetic ring 83 is descending, the linkage moves downward with the spur rack 99. Under the meshing transmission action of the spur rack 99 and the driving gear 98, the spur rack 99 descends to drive the main shaft 97 to rotate. Under the longitudinal transmission action of the bevel gear transmission member 96, the driven shaft 93 rotates following the main shaft 97, and finally the driven gear 92 rotates. Under the meshing transmission action of the driven gear 92 and the arc-shaped rack 91, the second annular water tank 82 is driven to rotate. The rotation of the second annular water tank 82 changes the spray angle of the second water spray holes thereon, which is used to make up for the gap and spray blind angle between the two adjacent second water spray holes, thereby improving the comprehensiveness and uniformity of the heat exchange of the reaction tube 2. When the thermal magnetic ring 83 resets upward, under the transmission action, the second annular water tank 82 is also driven to rotate and reset.

[0059] S4: When the cooling water is sprayed out from the first annular water reservoir 12, it will directly spray onto the curved surface at the bottom of the reaction tube 2. Due to the restriction of the cooling water by the deflector 13, the cooling water does not fall vertically. Instead, it is guided by the inner wall of the deflector 13 and slides along the curved surface at the bottom of the reaction tube 2. The lowermost heat exchange component 8 will also simultaneously drive the water blocking ring 15 to release the obstruction of the first water spray hole 18 on the first annular water reservoir 12, and the first annular water reservoir 12 is driven to rotate in conjunction with it.

[0060] S5: The cooled cooling water is finally discharged to the outside through the return pipe 5.

9. A method for using a high-efficiency chlorinated paraffin production device with waste heat utilization function, which is applied to the high-efficiency chlorinated paraffin production device with waste heat utilization function as claimed in claim 8, characterized in that: The following steps are involved: S1: Chlorine gas and chlorinated paraffin are introduced into the interior of the reaction tube (2), and the stirring assembly (7) stirs and reacts them. Heat is generated during the reaction, and cooling water enters the interior of the second annular water tank (82) through the water injection pipe (85) and the metal hose (84). The heat inside the reaction tube (2) increases the temperature of the thermal magnetic ring (83). When the temperature of the thermal magnetic ring (83) gradually increases, it will generate magnetism that attracts the permanent magnetic ring (811). Therefore, under the action of the magnetic attraction between the thermal magnetic ring (83) and the permanent magnetic ring (811), the thermal magnetic ring (83) is attracted to move toward the bearing ring (89) and the spring (813) is compressed. Since the thermal magnetic ring (83) is separated from the interior of the second annular water tank (82), it will release its obstruction to the second water spray hole on the second annular water tank (82). Therefore, the cooling water inside the second annular water tank (82) will be sprayed out and sprayed onto the outer wall surface of the reaction tube (2); S2: The water sprayed from the inside of the second annular water tank (82) not only cools the reaction tube (2), but also cools the thermal magnetic ring (83). After the thermal magnetic ring (83) cools down, its own magnetic force disappears. Under the elastic reset action of the spring (813), the thermal magnetic ring (83) returns to the inside of the second annular water tank (82) to block the second water spray hole. S3: When the thermal magnetic ring (83) is descending, the linkage brings the spur rack (99) downward. Under the meshing transmission action of the spur rack (99) and the driving gear (98), the spur rack (99) descends to drive the main shaft (97) to rotate. Under the longitudinal transmission action of the bevel gear transmission member (96), the driven shaft (93) rotates following the main shaft (97), and finally the driven gear (92) rotates. Under the meshing transmission action of the driven gear (92) and the arc-shaped rack (91), the second annular water tank (82) is driven to rotate. The rotation of the second annular water tank (82) changes the spray angle of the second water spray hole thereon, which is used to make up for the gap and spray dead angle between the two adjacent second water spray holes, thereby improving the comprehensiveness and uniformity of the heat exchange of the reaction cylinder (2). When the thermal magnetic ring (83) is reset upward, under the transmission action, the second annular water tank (82) is also driven to rotate and reset. S4: When the cooling water is sprayed out from the inside of the first annular water tank (12), it will directly spray onto the curved surface at the bottom of the reaction tube (2). Due to the restriction of the cooling water by the guide cover (13), the cooling water is prevented from falling vertically. Instead, it is guided by the inner wall of the guide cover (13) and slides along the curved surface at the bottom of the reaction tube (2). The lowermost heat exchange component (8) will also simultaneously drive the water blocking ring (15) to release the obstruction of the first water spray hole (18) on the first annular water tank (12), and drive the first annular water tank (12) to rotate in conjunction with it. S5: The cooled cooling water is finally discharged through the return pipe (5).
