Description

Technical Field

[0001] The utility model relates to the technical field of reactors, and more specifically to an automatic pressure relief protection device for a reactor. Background Art

[0002] Traditional reactors usually rely on the operator's experience and judgment to manually control the pressure, or set up pressure gauges and safety valves to perform basic pressure monitoring and manual pressure relief. However, this method has obvious limitations, such as rapid pressure changes during the reaction process, the operator may not be able to respond in time, or there are problems with the accuracy of the pressure gauge and the reliability of the safety valve. Therefore, in view of this, the existing structure and deficiencies are studied and improved, and an automatic pressure relief protection device for the reactor is provided, in order to achieve a more practical purpose. Utility Model Content

[0003] In order to overcome the above defects of the prior art, the utility model provides an automatic pressure relief protection device for a reactor to solve the problems existing in the above background technology.

[0004] The utility model provides the following technical solution: an automatic pressure relief protection device for a reactor, comprising a device main body, the device main body comprising a reactor body, a pressure relief mechanism being arranged on the reactor body, the pressure relief mechanism comprising a pressure relief pipe, a control panel and a pressure sensor, the pressure relief pipe being communicated with the interior of the reactor body, the control panel being mounted on the top end of the reactor body, the pressure sensor being mounted on the inner wall surface of the reactor body, a hydraulic cylinder being mounted inside the pressure relief pipe, a sealing plug being connected to the bottom end of the hydraulic cylinder, and a pressure relief port being mounted on one side of the pressure relief pipe.

[0005] During use, the pressure threshold is set through the control panel. The pressure sensor can detect the pressure changes inside the kettle in real time and feed back the data to the control panel. When the pressure sensor detects abnormal pressure, the control panel will send a signal to start the hydraulic cylinder. When the hydraulic cylinder starts, the sealing plug will open, allowing the pressure in the kettle to be discharged through the pressure relief port. Compared with traditional reactors, this application can realize real-time monitoring and automatic adjustment of pressure, avoiding safety accidents caused by the operator's inability to respond in time, and providing strong guarantee for the safe and efficient operation of chemical production.

[0006] Furthermore, a dust-proof gauze is installed inside the pressure relief port to prevent dust, impurities or other particles in the external environment from entering the reactor.

[0007] Furthermore, there are two pressure sensors. When one sensor fails or has an error, the other sensor can still work normally and provide valid pressure data. This redundant design can greatly reduce the safety risk caused by the failure of a single sensor.

[0008] Furthermore, an end cover is installed at the top end of the pressure relief pipe in a detachable manner, and the end cover is fixedly connected to the hydraulic cylinder, which is more convenient when maintaining or replacing parts.

[0009] Furthermore, a sealing rubber ring is provided at the connection between the sealing plug and the inner wall of the pressure relief pipe to ensure the sealing performance.

[0010] Furthermore, the pressure sensor, control panel and hydraulic cylinder are electrically connected.

[0011] Technical effects and advantages of the utility model:

[0012] 1. The utility model is provided with a pressure relief mechanism. When this design is adopted, the pressure threshold is set through the control panel during use. The pressure sensor can detect the pressure change inside the kettle in real time and feed back the data to the control panel. When the pressure sensor detects abnormal pressure, the control panel will send a signal to start the hydraulic cylinder. When the hydraulic cylinder is started, the sealing plug will open, allowing the pressure in the kettle to be discharged through the pressure relief port. Compared with the traditional reactor, this application can realize real-time monitoring and automatic adjustment of pressure, avoid safety accidents caused by the operator's inability to respond in time, and provide strong guarantee for the safe and efficient operation of chemical production.
