Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, specifically a pressure reaction vessel used in chemical production. Background Technology

[0002] In chemical production processes, pressure reactors are one of the commonly used pieces of equipment, and they need to maintain a certain pressure inside to ensure the normal progress of chemical reactions.

[0003] However, since excessive gas or pressure fluctuations may be generated during the reaction process, if the pressure is not adjusted in a timely and effective manner, it may lead to excessive pressure inside the reactor, thereby causing safety accidents such as explosions, which seriously threaten the lives of production personnel and the normal operation of production equipment.

[0004] However, existing pressure reactors have shortcomings in pressure relief and regulation, failing to adequately meet the safety and stability requirements of chemical production. This is especially true for reactors that rely primarily on rupture discs for pressure relief. Rupture discs are disposable devices, resulting in excessive costs. Furthermore, the gas flow generated during rupture can cause the entire reactor to shake, disrupting the internal chemical reactions and potentially leading to more serious safety accidents. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model discloses a pressure reactor for chemical production, which solves the problems mentioned in the background art. This pressure reactor can effectively withstand pressure and release the pressure in stages, thereby avoiding malfunctions of the pressure reactor.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pressure reactor for chemical production, comprising a reactor body, a pressurization pipeline at the bottom of the reactor body, and a pressure relief module at the top of the reactor body;

[0007] The pressure relief module includes a cylindrical outer shell, the lower end of which is connected to the interior of the reactor body. The upper half of the cylindrical outer shell has an elongated protrusion, and several vent holes are symmetrically arranged on both sides of the protrusion, evenly distributed along the long side of the protrusion. The pressure relief module has an internal sealing ring. When the sealing ring moves beyond a preset height under pressure, the vent holes will gradually open in stages, allowing the high-pressure gas inside the reactor body to be discharged through the vent holes, thus achieving controllable pressure relief.

[0008] Preferably, the pressure relief module has a guide post inside, and along the direction of the guide post, from top to bottom, there are an electromagnet, a trigger switch, a spring, and a sealing ring; the spring and the sealing ring are sequentially sleeved on the guide post, the electromagnet is located at the upper end of the columnar shell, the trigger switch is located at the lower end of the electromagnet, the electromagnet is in a normally closed state, the upper end of the sealing ring contacts the trigger switch, after the trigger switch receives a signal, the electromagnet opens, the spring is located between the bottom end face of the electromagnet and the top end face of the upper sealing ring, and the spring is made of a magnetic material.

[0009] Preferably, the bottom of the guide post is provided with a snap ring, the outer diameter of which is larger than the inner diameter of the lower sealing ring.

[0010] Preferably, the sealing ring includes an upper sealing ring, a guide sleeve, and a lower sealing ring. The guide sleeve is located between the upper sealing ring and the lower sealing ring. The top of the upper sealing ring is embedded with a magnetic layer. The end face of the lower sealing ring is provided with an air passage. As the lower sealing ring moves upward, the number of exhaust holes gradually increases.

[0011] Preferably, the guide sleeve and the guide post are fitted together by a sliding fit.

[0012] Preferably, the bottom of the pressure reactor body is equipped with a main motor and an auxiliary motor, and gas is input into the interior of the reactor body through the operation of the main motor and the auxiliary motor.

[0013] Preferably, a pressure regulating valve is provided on the pressurization pipeline.

[0014] Preferably, a dust filter is provided inside the exhaust port to prevent external impurities from entering the reactor body when the gas is discharged or enters the reactor body.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. In this utility model, the design of the pressure relief module enables the sealing ring to move beyond the preset height under pressure when the pressure inside the reactor is too high, allowing high-pressure gas to be discharged through the exhaust port. Moreover, as the lower sealing ring gradually moves upward, the number of exhaust ports gradually increases. Through the coordinated operation of multiple components such as the guide column, sealing ring, spring, and electromagnet within the pressure relief module, graded pressure relief can be achieved according to the pressure level, effectively avoiding the danger caused by sudden pressure release.

[0017] 2. This utility model can precisely adjust the pressure, ensure safety through graded pressure relief, has a stable structure, and has both dustproof and heat preservation functions. It effectively solves the shortcomings of existing equipment in pressure control and safety protection, and meets the safety and stability requirements of chemical production.

[0018] 3. This utility model has a strong adaptability.

[0027] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0028] Example: Figures 1-5 As shown, a pressure reactor for chemical production includes a reactor body 2. A pressurization pipeline is provided at the bottom of the reactor body 2. A main motor 201 and an auxiliary motor 202 are provided at the bottom of the pressure reactor body 2. Gas is input into the interior of the reactor body 2 through the operation of the main motor 201 and the auxiliary motor 202. A pressure regulating valve is provided on the pressurization pipeline.

[0029] The reactor body 2 is equipped with a pressure relief module at its top. The pressure relief module includes a cylindrical outer shell 1, the lower end of which is connected to the interior of the reactor body 2. The upper half of the cylindrical outer shell 1 has an elongated protrusion, and several vent holes 104 are symmetrically arranged on both sides of the elongated protrusion, evenly distributed along the long side of the protrusion. The pressure relief module contains a sealing ring and a guide post 108. From top to bottom, the column 108 is provided with an electromagnet 109, a trigger switch 106, a spring 105, and a sealing ring. A retaining ring 110 is provided at the bottom of the guide post 108. The outer diameter of the retaining ring 110 is larger than the inner diameter of the lower sealing ring 101, effectively preventing the lower sealing ring 101 from falling off and entering the reactor. The spring 105 and the sealing ring are sequentially fitted onto the guide post 108. The electromagnet 109 is located at the upper end of the columnar outer shell 1. The sealing ring includes an upper sealing ring 102, a guide sleeve 107, and a lower sealing ring. Ring 101, the guide sleeve 107 is located between the upper sealing ring 102 and the lower sealing ring 101, the guide sleeve 107 and the guide post 108 are in a sliding fit, the top of the upper sealing ring 102 is embedded with a magnetic layer, the end face of the lower sealing ring 101 is provided with an air passage 103, when the lower sealing ring 101 moves upward step by step, the number of exhaust holes 104 that are open gradually increases, the trigger switch 106 is located at the bottom lower end of the electromagnet 109, and the spring 105 is located at the bottom of the electromagnet. Between the bottom end face of the magnet 109 and the top end face of the sealing ring, the spring 105 is made of a magnetically conductive material; the electromagnet 109 is in a normally closed state, and the upper end of the upper sealing ring 102 contacts the trigger switch 106. After the trigger switch 106 receives a signal, the electromagnet 109 opens. When the sealing ring moves under pressure beyond a preset height, the exhaust port 104 will be gradually opened in stages, and the high-pressure gas inside the reactor body 2 will be discharged through the exhaust port 104, thereby achieving controllable pressure relief.

[0030] The dust filter installed inside the exhaust port 104 prevents external dust and other impurities from entering the reactor body 2 during gas discharge or entry, thus avoiding interference with the chemical reaction and ensuring the purity and quality of the reaction. Meanwhile, the retaining ring 110 at the bottom of the guide column 108 prevents the lower sealing ring 101 from detaching from the bottom of the guide column 108 during movement, ensuring the structural stability and reliability of the pressure relief module.

[0031] In practical use, at the start of chemical production, the main motor 201 and auxiliary motor 202 are started, and through their operation, gas is introduced into the interior of the reactor body 2 through the pressurized pipeline. At the same time, the operator can adjust the pressure regulating valve on the pressurized pipeline according to the specific requirements of the chemical reaction to achieve precise control of the input gas pressure and ensure that the pressure inside the reactor body 2 meets the reaction conditions.

[0032] During normal operation of the reactor body 2, the electromagnet 109 of the pressure relief module is normally closed, the spring 105 is in its normal state, the upper sealing ring 102 and the lower sealing ring 101 are in their respective positions, and the vent 104 is closed, thus maintaining a stable pressure inside the reactor body 2. The heat insulation layer on the outer wall of the reactor body 2 effectively reduces heat loss and maintains a stable temperature inside the reactor body 2, which is beneficial for the chemical reaction.

[0033] When the pressure inside the reactor body 2 is too high, the upper sealing ring 102 contacts the trigger switch 106. Upon receiving the signal, the trigger switch 106 opens the electromagnet 109. At this time, the high-pressure gas inside the reactor body 2 pushes the lower sealing ring 101 upwards along the guide column 108. Since the end face of the lower sealing ring 101 has a gas passage 103, the gas can be transmitted upwards through the gas passage 103. As the lower sealing ring 101 rises, the upper sealing ring 102 also moves upwards under the influence of gas pressure and the magnetic force of the magnetic layer and the electromagnet 109, compressing the spring 105. When the lower sealing ring 101 moves upwards beyond a preset height, the high-pressure gas inside the reactor body 2 begins to be discharged through the exhaust port 104. Furthermore, as the lower sealing ring 101 continues to move upward, the number of vent holes 104 that are open gradually increases, achieving staged pressure relief, thereby effectively reducing the pressure inside the reactor and ensuring the safety of the reactor. As the vent holes 104 are open and pressure is relieved, the pressure inside the reactor gradually decreases, and the compression spring 105 will push the sealing ring downward to reset, and the sealing ring will re-close the vent hole 104 channel, restoring the sealed state. Moreover, this application allows for adjustment of the rated pressure relief pressure by replacing springs 105 with different elastic coefficients without disassembling the module, thus improving the flexibility of equipment pressure regulation.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
