Description

Technical Field

[0001] This utility model relates to the technical field of gas cooling, and in particular to a phthalic anhydride gas cooling device. Background Technology

[0002] In the production of phthalic anhydride, the reaction process generates a large amount of heat, causing a significant increase in the temperature and pressure of the reaction gases. To maintain the stability and safety of the reaction process, the high-temperature, high-pressure reaction gases need to be cooled.

[0003] Currently, phthalic anhydride gas cooling mainly utilizes cooling water to lower the temperature of the phthalic anhydride gas inside the pipeline. However, after the cooling water is used up, its temperature rises, reducing the efficiency of subsequent phthalic anhydride gas cooling. Therefore, this invention proposes a phthalic anhydride gas cooling device that differs from existing technologies to solve the above-mentioned technical problems. Utility Model Content

[0004] To address the aforementioned problem of reduced efficiency in cooling phthalic anhydride gas after the cooling water temperature rises after use, this invention provides a phthalic anhydride gas cooling device.

[0005] This utility model provides a phthalic anhydride gas cooling device, which adopts the following technical solution:

[0006] A phthalic anhydride gas cooling device includes a cooling box, in which multiple sets of heat dissipation pipes are uniformly embedded in the inner cavity of the cooling box. Both ends of each set of heat dissipation pipes are connected to a gas mixing pipe, and gas inlet and outlet pipes are connected at the middle position of each set of gas mixing pipes. A cooling component is installed at the middle position of the bottom wall of the cooling box. A water intake conversion component extending into the inner cavity of the cooling box is installed on one outer wall of the cooling box, and a water agitation component is installed on one outer wall of the cooling box.

[0007] By adopting the above technical solution, the phthalic anhydride gas preparation pipeline is connected to two sets of gas inlet and outlet pipes respectively, so that the phthalic anhydride gas can be introduced into the inner cavity of multiple sets of heat dissipation pipes through the gas mixing pipes. This allows the cooling water to come into contact with the outer wall of multiple sets of heat dissipation pipes, thereby automatically reducing the temperature of the phthalic anhydride gas through heat transfer. The cooling components reduce the temperature of the cooling water, and the water intake conversion component and water agitation component enable the cooling water in the inner cavity of the cooling box to circulate, resulting in a uniform water temperature distribution.

[0008] Optionally, the cooling assembly includes heat-conducting fins, which are fixedly embedded in the bottom wall of the cooling box, and a semiconductor cooling chip is installed on the bottom wall of the heat-conducting fins.

[0009] Optionally, a waterproof water temperature sensor is installed on the bottom wall of one side of the cooling box, and a PLC controller is installed in the middle of the top wall of the cooling box. The PLC controller is electrically connected to the waterproof water temperature sensor and the semiconductor cooling chip.

[0010] By adopting the above technical solution, the cooling water temperature in the inner cavity of the cooling box is automatically monitored by a waterproof water temperature detection sensor. When the water temperature is too high, the PLC controller automatically controls the semiconductor cooling chip to generate cooling energy. Under the action of the heat-conducting fins, the cooling energy can be transferred to the cooling water in the inner cavity of the cooling box, thereby automatically reducing the water temperature of the cooling water.

[0011] Optionally, the water intake conversion assembly includes a first mounting frame, which is fixed to the bottom of the outer wall of the cooling box. A water pump is installed on the bottom wall of the inner cavity of the first mounting frame. A second water pipe extending to the lower end of the inner cavity of the cooling box is installed at the input end of the water pump, and a first water pipe extending to the upper end of the inner cavity of the cooling box is installed at the output end of the water pump.

[0012] Optionally, the water agitation assembly includes a second mounting frame, which is provided in two sets. The two sets of the second mounting frames are respectively installed at the upper and lower ends of the outer wall of one side of the cooling box. A cylinder is installed in the inner cavity of each set of the second mounting frames. An agitation vertical plate is installed at the end of the horizontal output shaft of each set of cylinders. The agitation vertical plate is movably sleeved on the outer wall of multiple sets of heat dissipation pipes.

[0013] By adopting the above technical solution, the water pump is started and the second water pipe automatically draws the cooling water from the lower end of the cooling box cavity and circulates it into the upper end of the cooling box cavity through the first water pipe. At the same time, multiple sets of cylinders are activated to extend and retract, which can drive the stirring vertical plate to move horizontally on the outer wall of multiple sets of heat dissipation pipes. This allows the cooling water to flow in the inner cavity of the cooling box, resulting in a uniform water temperature distribution.

[0014] Optionally, a drain pipe is installed on the bottom wall of the other side of the cooling box, and a water supply pipe is installed on one side of the top wall of the cooling box.

[0015] By adopting the above technical solution, opening the control valve on the water supply pipe facilitates the injection of cooling water into the inner cavity of the cooling box, and opening the control valve on the drain pipe allows the cooling water in the inner cavity of the cooling box to be discharged through the drain pipe.

[0016] Optionally, the bottom wall of the cooling box is equipped with multiple sets of support legs, and each set of support legs is equipped with a caster wheel at its bottom.

[0017] By adopting the above technical solution, the position of the phthalic anhydride gas cooling device can be easily moved using multiple sets of casters.

[0018] Optionally, a transparent liquid level window is installed at the upper end of the front side wall of the cooling box.

[0019] By adopting the above technical solution, the transparent liquid level window allows staff to conveniently monitor the liquid level inside the cooling tank in real time.

[0020] In summary, this utility model has at least one of the following beneficial effects:

[0021] Phthalic anhydride gas is introduced into the inner cavity of multiple heat dissipation pipes through a gas mixing pipe, allowing the cooling water to come into contact with the outer wall of the heat dissipation pipes and thus automatically reduce the temperature of the phthalic anhydride gas through heat transfer.

[0022] The water pump is started and the water in the cooling box cavity is circulated by the second water pipe and the first water pipe. Multiple sets of cylinders are activated to extend and retract, which can drive the stirring vertical plate to move horizontally in sync. This allows the cooling water to flow in the cooling box cavity, resulting in a uniform water temperature distribution.

[0023] When the semiconductor cooling chip is energized, it generates cooling energy, which is then transferred to the cooling water inside the cooling chamber by the heat-conducting fins. This automatically lowers the temperature of the cooling water, ensuring the effective cooling of phthalic anhydride gas. Attached Figure Description

Gas inlet and outlet pipes 2 are connected at the middle position of the two sets of gas mixing pipes 3. The gas inlet and outlet pipes 2, gas mixing pipes 3 and heat dissipation pipes 16 are all copper pipes. A connecting flange is installed at the end of the gas inlet and outlet pipes 2.

[0029] Please refer to the attached diagram in the instruction manual. Figure 1 A cooling assembly is installed in the middle of the bottom wall of the cooling box 15. The cooling assembly includes heat-conducting fins 8, which are fixedly embedded in the middle of the bottom wall of the cooling box 15. Multiple sets of heat-conducting rods are evenly installed on the top wall of the heat-conducting fins 8. A semiconductor cooling chip 7 is installed on the bottom wall of the heat-conducting fins 8. A waterproof water temperature detection sensor 11 is installed on the bottom wall of one side of the cooling box 15. A PLC controller 17 is installed in the middle of the top wall of the cooling box 15. The PLC controller 17 is electrically connected to the waterproof water temperature detection sensor 11 and the semiconductor cooling chip 7.

[0030] The phthalic anhydride gas preparation pipeline is connected to two sets of gas inlet and outlet pipes 2, so that the phthalic anhydride gas can be introduced into the inner cavity of multiple sets of heat dissipation pipes 16 through the gas mixing pipe 3. This allows the cooling water to come into contact with the outer wall of the multiple sets of heat dissipation pipes 16, thereby automatically reducing the temperature of the phthalic anhydride gas through heat transfer. Under the action of the waterproof water temperature detection sensor 11, the cooling water temperature in the inner cavity of the cooling box 15 is automatically monitored. When the water temperature is too high, the PLC controller 17 automatically controls the semiconductor cooling chip 7 to be energized to generate cooling energy. Under the action of the heat-conducting fins 8, the cooling energy can be transferred to the cooling water in the inner cavity of the cooling box 15, thereby automatically reducing the water temperature of the cooling water and ensuring the cooling effect of the phthalic anhydride gas.

[0031] Please refer to the attached diagram in the instruction manual. Figure 1 A water intake conversion assembly is installed on one side of the outer wall of the cooling box 15. The water intake conversion assembly includes a first mounting frame 4, which is fixed to the bottom of the outer wall of the cooling box 15. A water pump 5 is installed on the bottom wall of the inner cavity of the first mounting frame 4. A second water pipe 6 extending to the lower end of the inner cavity of the cooling box 15 is installed at the input end of the water pump 5, and a first water pipe 1 extending to the upper end of the inner cavity of the cooling box 15 is installed at the output end of the water pump 5.

[0032] Please refer to the attached diagram in the instruction manual. Figure 1A water agitation assembly is installed on one side of the outer wall of the cooling box 15. The water agitation assembly includes a second mounting frame 14. Two sets of second mounting frames 14 are provided. The two sets of second mounting frames 14 are respectively installed at the upper and lower ends of one side of the outer wall of the cooling box 15. A cylinder 13 is installed in the inner cavity of each set of second mounting frames 14. An agitation vertical plate 12 is installed at the end of the horizontal output shaft of the two sets of cylinders 13. The agitation vertical plate 12 is movably sleeved on the outer wall of multiple sets of heat dissipation pipes 16.

[0033] The water pump 5 is started and the second water pipe 6 automatically draws the cooling water from the lower end of the inner cavity of the cooling box 15 and circulates it into the upper end of the inner cavity of the cooling box 15 through the first water pipe 1. At the same time, multiple sets of cylinders 13 are activated to extend and retract, which can drive the stirring vertical plate 12 to move horizontally on the outer wall of multiple sets of heat dissipation pipes 16, so that the cooling water can flow in the inner cavity of the cooling box 15, thereby making the water temperature distribution uniform.

[0034] Please refer to the attached diagram in the instruction manual. Figure 1 and 2 A drain pipe 19 is installed on the bottom wall of the other side of the cooling box 15, and a water supply pipe 18 is installed on one side of the top wall of the cooling box 15. Control valves are installed on the outside of both the water supply pipe 18 and the drain pipe 19. Opening the control valve on the water supply pipe 18 injects an appropriate amount of cooling water into the inner cavity of the cooling box 15. Opening the control valve on the drain pipe 19 allows the cooling water in the inner cavity of the cooling box 15 to be discharged through the drain pipe 19, thus reducing the amount of cooling water in the inner cavity of the cooling box 15 and consequently reducing the weight of the phthalic anhydride gas cooling device, facilitating its subsequent relocation.

[0035] Please refer to the attached diagram in the instruction manual. Figure 1 and 2 The bottom wall of the cooling box 15 is equipped with multiple sets of support legs 9, which are located on the outer side of the semiconductor cooling chip 7. Each set of support legs 9 has a caster wheel 10 at its bottom. The caster wheel 10 is a self-locking universal wheel. The position of the phthalic anhydride gas cooling device is moved by the caster wheel 10.

[0036] Please refer to the attached diagram in the instruction manual. Figure 1 and 2 A transparent liquid level window 20 is installed at the upper end of the front side wall of the cooling box 15. The transparent liquid level window 20 allows staff to easily monitor the liquid level inside the cooling box 15 in real time.

[0037] Working principle: When using the phthalic anhydride gas cooling device, the device is moved to an appropriate position by multiple sets of casters 10. The phthalic anhydride gas preparation pipe is connected to two sets of gas inlet and outlet pipes 2, so that the phthalic anhydride gas can flow into the inner cavity of multiple sets of heat dissipation pipes 16 through the gas mixing pipe 3. The control valve on the water supply pipe 18 is opened to inject an appropriate amount of cooling water into the inner cavity of the cooling box 15, so that the cooling water can contact the outer wall of the multiple sets of heat dissipation pipes 16, thereby automatically reducing the temperature of the phthalic anhydride gas through heat transfer.

[0038] The water pump 5 is started and the second water pipe 6 automatically draws cooling water from the lower end of the inner cavity of the cooling box 15 and circulates it into the upper end of the inner cavity of the cooling box 15 through the first water pipe 1. At the same time, multiple sets of cylinders 13 are activated to extend and retract, which can drive the stirring vertical plate 12 to move horizontally on the outer wall of multiple sets of heat dissipation pipes 16. This allows the cooling water to flow in the inner cavity of the cooling box 15, resulting in a uniform water temperature distribution. With the help of the transparent liquid level window 20, it is convenient for the staff to check the liquid level inside the cooling box 15 in real time.

[0039] The waterproof water temperature sensor 11 automatically monitors the cooling water temperature inside the cooling chamber 15. When the water temperature is too high, the PLC controller 17 automatically controls the semiconductor cooling chip 7 to generate cooling. Under the action of the heat-conducting fins 8, the cooling can be transferred to the cooling water inside the cooling chamber 15, thereby automatically reducing the water temperature and ensuring the cooling effect of phthalic anhydride gas. The control valve on the drain pipe 19 is opened so that the cooling water inside the cooling chamber 15 can be discharged through the drain pipe 19, which reduces the amount of cooling water inside the cooling chamber 15 and thus reduces the weight of the phthalic anhydride gas cooling device, making it easier to move it later.
