Description

Technical Field

[0001] This utility model belongs to the field of high-pressure reactor technology, specifically relating to a lightweight, high-pressure resistant reactor for explosive reactions. Background Technology

[0002] High-pressure reactors are key equipment for conducting high-temperature and high-pressure reactions in fields such as chemical engineering, pharmaceuticals, and materials synthesis. In some rapid polymerization, decomposition, or catalytic reactions, the reaction releases a large amount of gas and heat instantaneously, forming an "explosive reaction" that causes a sharp increase in pressure inside the reactor.

[0003] Existing high-pressure reactors are mostly constructed from heavy metals such as stainless steel and alloy steel to ensure their pressure resistance. However, this structure results in heavy equipment, inconvenient movement, high thermal inertia, and high manufacturing costs. For explosive reactions, although the traditional heavy reactor body can withstand high pressure, it lacks rapid pressure relief and active safety protection mechanisms, and there is still a risk of explosion in the event of overpressure. In addition, the thick reactor walls are not conducive to the rapid removal of reaction heat, making it difficult to control the temperature rise caused by explosive reactions.

[0004] Therefore, this invention proposes a lightweight, high-pressure resistant reactor for explosive reactions. Utility Model Content

[0005] The purpose of this invention is to provide a lightweight, high-pressure resistant reactor for explosive reactions, which combines lightweight and high pressure resistance and can effectively cope with explosive reactions.

[0006] The specific technical solution adopted by this utility model is as follows: A lightweight, high-pressure resistant reactor for explosive reactions includes a lid and a body. The lid is provided with a feed inlet, a pressure relief port, and temperature and pressure measuring ports. The body includes an inner liner made of lightweight metal material and a composite material reinforcement layer tightly wrapped around the outer wall of the inner liner by a fiber winding process. The lid and the body are connected by a bolted quick-opening structure.

[0007] Preferably, the lightweight metal material is a titanium alloy or a high-strength aluminum alloy. These materials have extremely high specific strength, and as an inner liner, they can both bear pressure and significantly reduce weight. The lid of the vessel is provided with a sealing strip, which is in close contact with the upper end face of the vessel body.

[0008] Preferably, the composite material reinforcement layer is a carbon fiber composite material layer or an aramid fiber composite material layer. The fiber composite material has extremely high tensile strength and fatigue resistance. By winding it together with the metal inner liner, a synergistic reinforcement effect of "pressure bearing-constraint" is formed, which together withstands extremely high internal pressure and is the core of achieving lightweight and high pressure resistance.

[0009] Preferably, the pressure relief port is connected to a rupture disc device. As a non-self-closing safety relief device, the rupture disc can rupture rapidly when the pressure instantly exceeds the set limit value, thereby achieving instantaneous overpressure relief. It is particularly suitable for protecting equipment safety under explosive reactions.

[0010] Preferably, the inner wall of the vessel body and the inner surface of the vessel lid are coated with a corrosion-resistant coating, which can protect the metal liner from corrosion by the reactants and extend the service life of the equipment.

[0011] Preferably, a lightweight cooling coil is integrated on the outer bottom of the vessel body. When an explosive reaction occurs, the heat of reaction can be quickly removed by rapidly introducing a cooling medium into the coil, thus suppressing further increases in pressure and temperature.

[0012] Preferably, the vessel body is fitted with a protective shell, and the space between the protective shell and the vessel body is filled with energy-absorbing buffer material. This structure can effectively absorb impact energy in the event of rupture fragment release or extreme situations, protecting external personnel and equipment and providing secondary safety protection.

[0013] The technical effects achieved by this utility model are as follows: This utility model is lightweight and high-strength: it adopts a composite structure with a metal inner liner and a composite material reinforcement layer, which makes full use of the extremely high specific strength and designability of composite materials. While ensuring pressure resistance far exceeding that of traditional steel kettles, it significantly reduces the weight of the equipment, making it easy to move and install.

[0014] This invention boasts high safety: Addressing the rapid pressure surge characteristic of explosive reactions, a rupture disc is incorporated as an active pressure relief device, offering rapid response and high reliability. The external protective shell and energy-absorbing buffer layer provide secondary protection, forming a multi-layered safety assurance system.

[0015] This invention offers highly efficient temperature control: the lightweight composite structure of the vessel has a small heat capacity, and combined with the lightweight cooling coil integrated at the bottom of the vessel, it can achieve rapid cooling of the reaction system, effectively control the temperature rise caused by the explosive reaction, and avoid runaway reaction.

[0016] This invention features excellent corrosion resistance: the choice of a corrosion-resistant coating on the inner wall and a titanium alloy / high-strength aluminum alloy inner liner enables the equipment to adapt to a wider range of corrosive reaction media. Attached Figure Description

The external protective shell and energy-absorbing buffer layer provide secondary protection, forming a multi-layered safety assurance system.

[0029] like Figures 1-4 As shown, this utility model has high temperature control efficiency: the lightweight composite structure of the vessel body has a small heat capacity, and with the lightweight cooling coil integrated at the bottom of the vessel, it can achieve rapid cooling of the reaction system, effectively control the temperature rise caused by the explosive reaction, and avoid the reaction from getting out of control.

[0030] like Figures 1-4 As shown, this utility model has good corrosion resistance: the choice of corrosion-resistant coating on the inner wall and titanium alloy / high-strength aluminum alloy inner liner enables the equipment to adapt to a wider range of corrosive reaction media.
