Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of reactors, in particular to a separate cooling module for a thermal polymerization reactor. Background Art
[0002] A reactor, broadly defined as a container for physical or chemical reactions, achieves the heating, evaporation, cooling, and low-speed mixing required by the process through structural design and parameter configuration. Reactors are commonly used in the petroleum, chemical, rubber, pesticide, dye, pharmaceutical, and food industries as pressure vessels for processes such as vulcanization, nitration, hydrogenation, hydrocarbonization, polymerization, and condensation. However, during the reaction in a thermal polymerization reactor, the temperature must be maintained within a certain range—neither too high, which would affect the reaction, nor too low, which would inefficiently react. Most existing reactors lack a corresponding module. Utility Model Content
[0003] The purpose of the utility model is to provide a separate cooling module for a thermal polymerization reactor to solve the problems existing in the above-mentioned prior art.
[0004] The above technical objectives of the present invention are achieved through the following technical solutions:
[0005] A separate cooling module for a thermal polymerization reactor comprises a reactor body and a circulation system connected to the top of the reactor body, wherein the reactor body comprises a reaction part and a cooling part, wherein the cooling part is arranged on the top of the reaction part, and a plurality of micropores are evenly distributed on the side wall of the reaction part, a sealing plate is arranged between the reaction part and the cooling part, a circulating liquid outlet is arranged on one side of the cooling part, a circulating liquid inlet is arranged on the other side of the cooling part, a circulating liquid main pipe is arranged on the inner top end of the cooling part, one end of the circulating liquid main pipe is fixedly installed inside the circulating liquid outlet, and the other end of the circulating liquid main pipe is fixedly installed inside the circulating liquid inlet, and a plurality of evaporation tubes are evenly spaced at the bottom end of the circulating liquid main pipe.
[0006] By adopting the above technical solution, the reaction part and the cooling part are arranged separately, which can prevent the circulating liquid and other liquids in the cooling part from affecting the normal reaction of the chemical substances in the reaction part. The cooling part is sealed as a whole, and is filled with water. The thermal conductivity of water is excellent, and the heat can be transferred from the reaction part at the bottom of the partition to the evaporation tube in the cooling part. The evaporation tube and the circulating liquid main pipe are connected, and the interior of the evaporation tube and the circulating liquid main pipe is filled with low-boiling-point liquid. When the temperature of the reaction part as a whole rises to a certain bottom, the low-boiling-point liquid in the evaporation tube will boil and take away the heat from the water, so that the water can absorb more heat from the reaction part, and the boiling low-boiling-point liquid will move upward from the evaporation tube, and finally leave through the outlet end of the circulating liquid main pipe, and enter again from the inlet end of the circulating liquid main pipe after being cooled by the circulation system.
[0007] In a further embodiment, a water injection pipe and a water extraction pipe are bolted and fixed to the top of the cooling part, and the water injection pipe and the water extraction pipe are both arranged vertically downward. A first sealing device is fixedly installed on the top of the water injection pipe and the water extraction pipe, and the bottom end of the water injection pipe is higher than the bottom end of the water extraction pipe.
[0008] By adopting the above technical solution, the water injection pipe can quickly inject water into the interior of the cooling part, while the water extraction pipe can extract high-temperature water from the cooling part. The water injection pipe and the water extraction pipe are both connected to the water system, but the accuracy of direct water extraction and injection is too low. Therefore, the main cooling is still through the evaporation tube and the circulating liquid main pipe.
[0009] In a further embodiment, the water injection pipe includes a first pipe, a second pipe and a third pipe, the top of the first pipe is detachably installed with a first sealing device, the bottom end of the first pipe is connected to the top flange of the second pipe, the bottom end of the second pipe is connected to the top flange of the third pipe, the water extraction pipe includes a fourth pipe, a fifth pipe and a sixth pipe, the top of the fourth pipe is detachably installed with a first sealing device, the bottom end of the fourth pipe is connected to the top flange of the fifth pipe, and the bottom end of the fifth pipe is connected to the top flange of the sixth pipe.
[0010] By adopting the above technical solution, the water injection pipe is not formed in one piece, but is composed of multiple pipes, and the multiple pipes are connected by flanges. This connection method is easy to disassemble, has high strength and good sealing performance, and can adapt to different kettle sizes. It only needs to be freely installed according to needs.
[0011] In a further embodiment, a second sealing device is welded at the circulating liquid inlet, and the second sealing device includes an upper fixed plate and a lower fixed plate, a first accommodating groove is provided at the bottom of the upper fixed plate close to the kettle body, and a second accommodating groove is provided at the top of the lower fixed plate close to the kettle body, through holes are coaxially provided on the upper fixed plate and the lower fixed plate, the upper fixed plate and the lower fixed plate are connected by bolts, and a third sealing device is welded at the circulating liquid outlet, and the structures of the second sealing device and the third sealing device are consistent.
[0012] By adopting the above technical solution, a one-way valve is provided on the second sealing device, and the low-boiling-point circulating liquid can only enter from the one-way valve but cannot exit from the one-way valve. The low-boiling-point circulating liquid is not connected to the external circulation system at all times, which will cause the temperature of the reaction part to be too low. When the temperature approaches the preset threshold, the boiling low-boiling-point circulating liquid will leave from the outlet and be cooled through the circulation system, and finally enter the evaporation tube again through the one-way valve, taking away the heat of the water inside the cooling part.
[0013] In a further embodiment, a pressure relief valve is provided at one end of the circulating liquid main pipe close to the circulating liquid outlet.
[0014] By adopting the above technical solution, the pressure relief valve can ensure that when the low-boiling-point circulating liquid is not boiling, the pressure in the evaporator tube and the circulating liquid main pipe is insufficient, causing the liquid to flow out from the outlet, thereby achieving the effect of automatic cooling by taking advantage of the physical properties of the low-boiling-point circulating liquid.
[0015] In a further embodiment, fixing frames are welded to both sides of the kettle body.
[0016] By adopting the above technical solution, the fixing frame can be bolted to the supporting column, so that the kettle body can be firmly fixed in mid-air, which is convenient for raw material transportation and maintenance.
[0017] In summary, the present invention has the following beneficial effects:
[0018] 1. The reaction part and the cooling part are set separately, which can prevent the circulating liquid and other liquids in the cooling part from affecting the normal reaction of the chemical substances in the reaction part. The cooling part is sealed as a whole and is filled with water. Water has excellent thermal conductivity and can conduct heat from the reaction part at the bottom of the partition to the evaporation tube in the cooling part.
[0019] 2. The arrangement of the circulating liquid main pipe and the evaporation pipe enables the evaporation pipe and the circulating liquid main pipe to be connected. The interior of the evaporation pipe and the circulating liquid main pipe is filled with a low-boiling-point liquid. When the overall temperature of the reaction part rises to a certain bottom, the low-boiling-point liquid in the evaporation pipe will boil and take away heat from the water, so that the water can absorb more heat from the reaction part. The boiling low-boiling-point liquid will move upward from the evaporation pipe and eventually leave through the outlet end of the circulating liquid main pipe. After cooling through the circulation system, it will re-enter the inlet end of the circulating liquid main pipe.
[0020] 3. The setting of the pressure relief valve can ensure that when the low-boiling-point circulating fluid is not boiling, the pressure in the evaporator tube and the circulating fluid main pipe is insufficient, causing the liquid to flow out from the outlet, thereby achieving the effect of automatic cooling by taking advantage of the physical properties of the low-boiling-point circulating fluid.

A pressure relief valve 9 is provided at one end of the circulating liquid main pipe 2 near the circulating liquid outlet. A plurality of evaporation tubes 3 are evenly spaced at the bottom of the circulating liquid main pipe 2. Fixed frames 10 are welded on both sides of the kettle body 1. Through the setting of the cooling part 12 and the reaction part 11, the two are separated by a sealing plate 13. The cooling part 12 is filled with water. At the same time, a circulating liquid main pipe 2 and a plurality of evaporation tubes 3 arranged at the bottom of the circulating liquid main pipe 2 are filled with low-boiling-point circulating liquid. When the water temperature exceeds a certain temperature, the low-boiling-point circulating liquid will boil, and the pressure relief valve 9 provided on one side of the circulating liquid main pipe 2 will be activated to input the high-temperature and boiling circulating liquid into the circulation system. After being cooled by the circulation system, it enters from the one-way valve on the other side of the circulating liquid main pipe 2, thereby achieving temperature control of the reaction part 11 within a certain range to ensure the normal reaction of the chemical raw materials inside it.
[0028] like Figure 1-Figure 2As shown, the top of the cooling part 12 is bolted with a water injection pipe 4 and a water extraction pipe 5, and the water injection pipe 4 and the water extraction pipe 5 are both arranged vertically downward. The tops of the water injection pipe 4 and the water extraction pipe 5 are fixedly installed with a first sealing device 6. The bottom end of the water injection pipe 4 is higher than the bottom end of the water extraction pipe 5. The water injection pipe 4 includes a first pipe, a second pipe and a third pipe.

When the reactor starts working, the circulation system also operates normally. The heat of the reaction part 11 is transferred along the partition to the water body inside the cooling part 12. The water body temperature rises and transfers heat to the evaporation tube 3. The low-boiling point liquid in the evaporation tube 3 boils after absorbing heat, and the pressure in the circulating liquid main pipe 2 increases. The pressure relief valve 9 on one side is opened, and the low-boiling point circulating liquid flows out of the pressure relief valve 9 and re-enters the circulation system. After the temperature drops in the circulation system, it enters the one-way valve again to continue the cooling cycle. In this process, the temperature of the reactor will be maintained at a roughly constant state.
