[0023] The following is combined with Figure 1-4, the technical solution of the utility model is further explained:

[0024] Example 1: Figure 1 and Figure 2As shown, a pressure relief pipe for cooling a reactor comprises a reactor body 1, a connecting pipe 2 is installed on the top of the reactor body 1, one side of the connecting pipe 2 is connected to an automatic pressure relief pipe 3, the inner wall of the automatic pressure relief pipe 3 is slidingly provided with a lifting slider 9, a pressure relief hole 11 is opened through the outer wall of one side of the automatic pressure relief pipe 3, and the pressure relief hole 11 is located above the lifting slider 9, an automatic pressure relief component is provided inside the automatic pressure relief pipe 3, and the automatic pressure relief component is used to control the position of the lifting slider 9 so that the pressure relief hole 11 is connected to the outside, the outer wall of one side of the automatic pressure relief pipe 3 is connected to a one-way valve 12 through a pipeline, and the connecting pipeline is connected to the pressure relief hole 11, and one end of the one-way valve 12 is connected to The air release pipe 13, one end of the air release pipe 13 is connected to a purification component, which is used to purify the gas discharged from the reactor due to pressure relief. The purification component includes a purification pipe 14, a separation filter 15 and an activated carbon layer 16. One end of the air release pipe 13 is connected to the purification pipe 14 through a flange. The separation filter 15 is installed at the top and bottom of the inner wall of the purification pipe 14. The activated carbon layer 16 is installed inside the purification pipe 14, and the activated carbon layer 16 is located on the inner side of the two groups of separation filters 15. The air release pipe 13 is curved, and the outlet of the air release pipe 13 is vertically downward. A sealing sleeve 10 is installed on the outside of the lifting slider 9, and the sealing sleeve 10 is in contact with the inner wall of the automatic pressure relief pipe 3. The kettle body 1 provides an installation position for the connecting pipe 2. The connecting pipe 2 allows the gas inside the reactor to enter the automatic pressure relief pipe 3 and complete the automatic pressure relief process inside the automatic pressure relief pipe 3. The automatic pressure relief pipe 3 provides an installation space for the automatic pressure relief component and the lifting slider 9, and provides an opening position for the pressure relief hole 11. The one-way valve 12 connects the pressure relief hole 11 and the air release pipe 13, and only allows the air inside the reactor to leak to the outside, and does not allow external gas to pass through the one-way valve 12. The air release pipe 13 provides a connection position for the purification component; the purification pipe 14 provides an installation position and installation space for the separation filter 15 and the activated carbon layer 16. The separation filter 15 fixes the activated carbon layer 16 inside the purification pipe 14 and can filter the particulate matter present in the gas during the reactor degassing process. The activated carbon layer 16 is used to adsorb the gas leaked from the reactor. Harmful substances in the released gas, the opening of the vent pipe 13 is set downward to avoid the discharged gas from spraying randomly; when the gas is released from the pressure relief hole 11 of the automatic pressure relief pipe 3 due to excessive pressure in the reactor, the released gas passes through the one-way valve 12, the vent pipe 13 and the purification pipe 14 in sequence, and is finally discharged to the external environment. During the circulation of the released gas inside the purification pipe 14, the separation filter 15 at the top of the purification pipe 14 intercepts the large particles of impurities in the pressure relief gas, and the activated carbon layer 16 on the inside of the separation filter 15 relies on its porous structure to absorb organic matter and odor in the pressure relief gas. The purification of the pressure relief gas by the purification pipe 14 prevents the harmful pressure relief gas in the reactor from directly entering the external environment and affecting the external environment. At the same time, the installation of the purification component through the flange facilitates the replacement of the purification component.

[0025] Example 2: Figure 1and Figure 3 As shown in the figure, the top of the automatic pressure relief pipe 3 is provided with a top cover 4 through threaded installation, the automatic pressure relief assembly includes a guide rod 5, a spring 7, a T-shaped block 8, the guide rod 5 is installed through the center of the top of the top cover 4, the spring 7 is connected to the inner wall of the top of the top cover 4, and the spring 7 is located outside the guide rod 5, the bottom end of the guide rod 5 is connected with the T-shaped block 8, and the T-shaped block 8 is composed of a disc and a round rod at the bottom center, the disc top end of the T-shaped block 8 is connected with the spring 7, and the round rod bottom end of the T-shaped block 8 is connected with the lifting block 9. The automatic pressure relief pipe 3 provides an installation position for the top cover 4, the top cover 4 provides an installation position for the guide rod 5 and the spring 7, the guide rod 5 provides an installation position for the T-shaped block 8, the spring 7 connects the inner wall of the top of the top cover 4 and the disc top of the T-shaped block 8, and the T-shaped block 8 connects the lifting block 9 and the guide rod 5, so that the guide rod 5 can provide a guiding action for the movement of the lifting block 9, and the lifting block 9 provides an installation position for the sealing sleeve 10, and the sealing sleeve 10 is in contact with the inner wall of the automatic pressure relief pipe 3 to ensure the sealing state in the pipeline before pressure relief; when the pressure inside the reaction kettle is too high, the pressure enters the automatic pressure relief pipe 3 through the communication pipe 2, the pressure pushes the lifting block 9 upwards, the lifting block 9 moves upwards under the guiding action of the guide rod 5, and in the process of rising, the spring 7 is extruded, until the height of the lifting block 9 is higher than the pressure relief hole 11, so that the high-pressure gas can enter the pressure relief passage through the pressure relief hole 11, through the automatic pressure relief assembly, the reaction kettle can automatically open the pressure relief passage due to the movement of the lifting block 9 pushed by the pressure during the cooling process, thereby realizing automatic pressure relief, and because of the existence of the spring 7, the lifting block 9 will not make a sudden jump action due to sudden change of pressure, thereby ensuring the stability of the sliding of the lifting block 9.

[0026] Example three: as Figure 1 , Figure 3 and Figure 4A column 17 is installed on the top of the connecting pipe 2, and an electric pressure gauge 18 is installed on the top of the column 17. A pressure measuring tube 19 is connected to the top of the connecting pipe 2, and the output end of the pressure measuring tube 19 is connected to the input end of the electric pressure gauge 18. The pressure measuring tube 19 is spirally wound on the outer surface of the column 17. An audible and visual alarm 20 is installed on the top of the connecting pipe 2, and the audible and visual alarm 20 is activated by a built-in controller. A top plate 6 is installed on the top of the guide rod 5, and a micro electric push rod 21 is symmetrically installed on the top of the top cover 4, and the micro electric push rod 21 is located on the outside of the guide rod 5. A push block is installed on the output end of the micro electric push rod 21, and the push block is located below the top plate 6. The connecting pipe 2 provides an installation position for the column 17 and a connection position for the pressure measuring tube 19. The column 17 provides an installation position for the electric pressure gauge 18. The pressure measuring tube 19 connects the connecting pipe 2 to the electric pressure gauge 18 so that the electric pressure gauge 18 can measure the pressure in the pipeline. The winding of the pressure measuring tube 19 can play a buffering role to prevent the sudden high pressure from impacting the electric pressure gauge 18. The sound and light alarm 20 installed on the top of the connecting pipe 2 can emit an alarm light and sound when the pressure in the pipeline is too high. The guide rod 5 provides an installation position for the top plate 6, and the top cover 4 provides an installation position for the micro-electric push rod 21. The micro-electric push rod 21 can extend upward so that the push block pushes the top plate 6, so that the top plate 6 drives the guide rod 5, T-block 8 and lifting slider 9 to rise; when the reactor is cooling, if the lifting slider 9 inside the automatic pressure relief pipe 3 is stuck for some reason and cannot be raised and lowered with the pressure changes in the pipeline, the pipeline between the reactor and the automatic pressure relief pipe 3 cannot be relieved. The hole 11 is connected to the outside world. When the electric pressure gauge 18 detects that the pressure in the pipeline is too high, the electric pressure gauge 18 sends a signal. The controller in the sound and light alarm 20 receives the signal sent by the electric pressure gauge 18, causing the sound and light alarm 20 and the micro electric push rod 21 to perform corresponding operations. The light of the sound and light alarm 20 flashes and an alarm sounds to remind nearby staff. The micro electric push rod 21 is internally set with a corresponding program to extend upward. The output end of the micro electric push rod 21 extends upward, so that the push block pushes the top plate 6 upward, driving the guide rod 5 and the lifting slider 9 to rise, so that the pipeline can be connected to the outside world through the pressure relief hole 11. The pressure in the pipeline is detected by the electric pressure gauge 18, and when the pressure is detected to be too high, the sound and light alarm 20 is used to alarm to remind the staff, helping the staff to promptly understand the abnormal situation of the automatic pressure relief component, and through the pushing action of the micro electric push rod 21, the pipeline can be depressurized to avoid explosion caused by excessive pressure inside the pipeline.

[0027] Working principle: Before using the pressure relief pipe for cooling the reactor, you should first check whether there are any problems that affect the use of the pressure relief pipe for cooling the reactor. First, install the pressure relief pipe in a suitable position. When the pressure inside the reactor is too high, the pressure enters the automatic pressure relief pipe 3 through the connecting pipe 2. The pressure pushes the lifting slider 9 upward. The lifting slider 9 moves upward under the guidance of the guide rod 5 and squeezes the spring 7 during the rising process until the height of the lifting slider 9 is higher than the pressure relief hole 11, so that the high-pressure gas can enter the pressure relief channel through the pressure relief hole 11, thereby realizing automatic pressure relief. And because of the presence of the spring 7, the lifting slider 9 will not make an abrupt jump due to the sudden change in pressure, ensuring the sliding stability of the lifting slider 9; after the leaked gas is leaked from the pressure relief hole 11, it passes through the one-way valve 12, the air release pipe 13 and the purification pipe 14 in turn, and is finally discharged to the external environment. During the circulation of the leaked gas in the purification pipe 14, the partition filter at the top of the purification pipe 14 The net 15 intercepts large particles of impurities in the depressurized gas, and the activated carbon layer 16 on the inner side of the separation filter 15 relies on its porous structure to absorb organic matter and odor in the depressurized gas. The depressurized gas is purified by the purification pipe 14 to prevent harmful depressurized gas in the reactor from directly entering the external environment and affecting the external environment. At the same time, the installation of the purification component through the flange facilitates the replacement of the purification component. During the cooling process of the reactor, the electric pressure gauge 18 detects the internal pressure of the pipeline. If the lifting slider 9 inside the automatic pressure relief pipe 3 is stuck for some reason, the pipeline between the reactor and the automatic pressure relief pipe 3 cannot be depressurized through the pressure relief hole 11. The electric pressure gauge 18 will remind the staff through the sound and light alarm 20 when it detects that the pressure in the blade pipeline is too high, helping the staff to promptly understand the abnormal situation of the automatic pressure relief component, and through the pushing action of the micro electric push rod 21, the pipeline can be depressurized to avoid explosion caused by excessive pressure inside the pipeline.
