Description

Technical Field

[0001] This utility model relates to the field of explosion-proof technology for reaction vessels, and in particular to an explosion-proof structure and reaction vessel. Background Technology

[0002] In the chemical and related fields, reaction vessels are crucial equipment for various chemical reactions. They face the risk of explosion during operation, therefore, explosion-proof structures are necessary to ensure safety. Traditional explosion-proof structures for reaction vessels typically consist of metal valves, rupture discs, and other devices, as illustrated in the Chinese utility model patent "A Safety Production Explosion-proof Device" published under authorization announcement number CN215917356U. However, metal valves and rupture discs have the following drawbacks: 1. They are heavy, costly, and complex to install and maintain; 2. In certain chemical reaction environments, metal may react with reactants, hindering the original reaction or even causing new safety problems. Furthermore, metal is easily corroded, affecting the normal operation of the explosion-proof device; 3. For complex projects, the technical requirements and costs are higher, potentially increasing the equipment failure rate; 4. When the pressure inside the reaction vessel rises sharply, the activation of the metal explosion-proof device is often sudden, potentially generating a large impact force that can damage the equipment and the surrounding environment. Therefore, it is necessary to design a simpler and more effective explosion-proof structure to improve the safety of the reactor and reduce the probability of explosion accidents. Utility Model Content

[0003] In view of this, this utility model proposes an explosion-proof structure and a reaction vessel to solve the technical problems of existing explosion-proof devices for reaction vessels, such as high cost, complex installation and maintenance, easy corrosion failure, and low safety performance.

[0004] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0006] The mounting carrier has a mounting surface that matches the opening at the top of the reactor, and at least one explosion-proof hole is formed on the mounting surface;

[0007] At least one layer of explosion-proof film made of plastic is provided on the mounting surface to seal the explosion-proof hole.

[0008] In some embodiments, the mounting carrier includes a connecting cylinder and a cover plate, the connecting cylinder being adapted to the opening, the lower surface of the cover plate being fixedly connected to the connecting cylinder, and the upper surface of the cover plate forming the mounting surface.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] To address the technical problems of existing explosion-proof devices made of metal materials, such as high cost, complex installation and maintenance, susceptibility to corrosion and failure, and low safety performance, this utility model provides a novel explosion-proof structure and reactor. It is a simpler and more effective explosion-proof structure that improves the safety of the reactor and reduces the probability of explosion accidents.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model relates to an explosion-proof structure 100, which is disposed on the top of a reaction vessel 200. The explosion-proof structure 100 includes a mounting carrier 110 and at least one layer of explosion-proof membrane 120. The mounting carrier 110 has a mounting surface that matches the opening 201 at the top of the reaction vessel 200. At least one explosion-proof hole 101 is formed on the mounting surface. Multiple layers of the explosion-proof membrane 120 are sequentially disposed on the mounting surface to seal the explosion-proof hole 101.

[0028] It should be noted that the explosion-proof membrane 120 described in this utility model is made of plastic. The explosion-proof membrane 120 made of plastic has advantages such as light weight, low cost, and good flexibility. Under specific conditions, the explosion-proof membrane 120 made of plastic can withstand a certain pressure, and when the pressure exceeds its limit, it will rupture in a relatively gentle manner, releasing the pressure and thus achieving an explosion-proof function. Furthermore, the explosion-proof membrane 120 of this utility model can be customized according to the specific shape and size of the reaction vessel 200, making it easy to install and highly adaptable; it can also be used in combination with other materials to further improve its explosion-proof performance.

[0029] Therefore, the explosion-proof structure 100 described in this utility model applied to the reactor 200 has the advantages of lower cost and lighter weight compared with traditional metal explosion-proof devices. It does not place too much burden on the overall structure of the reactor 200, and the structure is simple, making it easy to install and maintain. At the same time, since the explosion-proof membrane of this utility model is made of plastic, it can prevent the components from being corroded and will not react chemically with the reactants, thus avoiding safety accidents due to failure. In addition, this utility model has a sensitive reaction. When the pressure exceeds the safety threshold, the plastic explosion-proof membrane can rupture quickly to release the pressure, resulting in a fast reaction speed and effectively improving the safety of the reactor.

[0030] In one embodiment, the explosion-proof membrane 120 is made of high-strength, high-temperature resistant, and corrosion-resistant plastic material. This material should have good ductility and toughness, be able to withstand a certain pressure without breaking, but be able to break quickly and release pressure when the preset pressure is exceeded.

[0031] In one embodiment, the explosion-proof membrane 120 can be multi-layered to increase the reliability of explosion protection. When one layer of explosion-proof membrane 120 is broken, the other layers of explosion-proof membrane 120 can still play an explosion-proof role to a certain extent, giving operators time to take emergency measures.

[0032] In one embodiment, the mounting carrier 110 includes a connecting cylinder 111 and a cover plate 112. The connecting cylinder 111 is adapted to the opening 201 so that the connecting cylinder 111 can be placed in the opening 201 and sealed during installation. The lower surface of the cover plate 112 is fixedly connected to the connecting cylinder 111, and the upper surface of the cover plate 112 forms the mounting surface.

[0033] In one embodiment, an explosion-proof hole 101 is provided on the upper surface of the cover plate 112. The explosion-proof hole 101 is circular and its diameter is equal to the diameter of the connecting cylinder 111. An explosion-proof membrane 120 is disposed on the mounting surface to cover the explosion-proof hole 101.

[0034] In one embodiment, the upper surface of the cover plate 112 may also be provided with a plurality of explosion-proof holes 101. The shape of the plurality of explosion-proof holes 101 may be circular, triangular or rectangular, and they are evenly arranged on the upper surface of the cover plate 112.

[0035] In one embodiment, the diameter of the cover plate 112 is 3 to 6 cm larger than the diameter of the connecting cylinder 111, preferably 5 cm, so as to achieve better sealing.

[0036] In one embodiment, the height of the connecting cylinder 111 is 8 to 12 cm, preferably 10 cm.

[0037] In one embodiment, the inner wall of the connecting cylinder 111 and the lower surface of the cover plate 112 are coated with an anti-corrosion layer.

[0038] In one embodiment, a fastener is also included for securing the explosion-proof film 120 to the mounting carrier 110.

[0039] In one embodiment, the fastener is a hemp rope.

[0040] In one embodiment, a pressure sensor and a controller are also included. The pressure sensor is disposed inside the reactor 200 and is signal-connected to the controller. The pressure sensor is used to monitor the internal pressure of the reactor 200 in real time. When the pressure value approaches a safety threshold, the controller activates an alarm device to issue an alarm, alerting the operator to take appropriate action.

[0041] In one embodiment, a safety discharge valve is also included, which is signal-connected to the controller. When the monitored pressure value approaches a safety threshold, the controller controls the safety discharge valve to open and release gas to ensure the safety of the reactor 200.

[0042] On the other hand, the present invention provides a reaction vessel 200, including a vessel body 210 and an explosion-proof structure 100. An opening 201 is provided at the center of the top of the vessel body 210, and the explosion-proof structure 100 is disposed in the opening 201.

[0043] The working principle of the explosion-proof structure and reaction vessel provided by this utility model is as follows:

[0044] When the connecting cylinder 111 of the explosion-proof structure 100 is installed in the opening 201, the cover plate 112 completely covers the opening 201 and is larger than the opening 201. Then, the explosion-proof membrane 120 is fixed to the upper surface of the cover plate 112 with fasteners, ensuring that the entire mounting surface is covered. During normal operation of the reactor 200, the explosion-proof membrane 120 remains stable and does not affect the normal operation of the reactor 200. When the negative pressure in the reactor 200 is low, the explosion-proof membrane 120 will bulge and expand. The blower is adjusted in time according to the degree of bulging of the explosion-proof membrane 120 at the top of the reactor 200. The magnitude of the negative pressure inside the reactor 200 is directly proportional to the gas flow. When the internal pressure of the reactor 200 exceeds the safety threshold, the explosion-proof membrane 120 can rupture in time to release the pressure, thereby preventing the reactor 200 from exploding.

[0045] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
