Description

Technical Field

[0001] The utility model relates to the technical field of reactor sample cooling, in particular to a high-temperature and high-pressure reactor sample rapid cooling device. Background Art

[0002] Reactors belong to the category of pressure vessels. They are special equipment that needs to be subject to safety supervision by government departments. They are industrial products developed with a combination of new materials, new technologies, and new processes. They are also catalysts for many new industries and are widely used. High-temperature and high-pressure reactors generally have thick walls and extremely harsh working conditions. Some commonly used materials are difficult to meet such requirements. Under ultra-high pressure and high temperature conditions, in addition to the ability of the material itself to withstand pressure, the water inside the reactor produces critical water under ultra-high pressure and high temperature conditions, which is extremely corrosive. Therefore, the material must have extremely strong stability. At the same time, due to high temperature and high pressure conditions, there are very high requirements for sealing. The high-temperature and high-pressure reactors currently used by people cannot meet the requirements of simulating the physical conditions 3,000 meters deep in the earth, which brings inconvenience to people's research.

[0003] The existing Chinese patent publication number is CN209476247U, which is an ultra-high pressure and high temperature reactor, comprising a reactor body, a sealing cone and a reactor body cap, a temperature measuring hole is arranged on the outside of the right side of the reactor body, a chemical reaction zone is arranged in the middle of the reactor body, a flange and a sealing bevel are arranged on the sealing cone, the sealing bevel is inserted into the chemical reaction zone of the reactor body, the reactor body cap is wrapped on the outside of the connection between the reactor body and the sealing cone, a buffer zone is arranged on the inside of the reactor body cap, and an observation hole is connected to one side of the buffer zone and the observation hole is connected to the outside. The product is reasonably designed. By using the cooperation of the reactor body, the sealing cone and the reactor body cap made of Hastelloy alloy, the buffer zone and the observation hole are added, and leakage can be easily observed; the sealing cone is provided with a flange, which can make the locking pressure of the thread of the reactor body cap pressed on the pressure surface of the flange to the maximum extent, and the pressure of the flange will basically not be transmitted to the sealing bevel, and no sealing medium is needed. It can withstand a pressure of 0-300MPa and a high temperature environment of 0-1200℃, meeting the use needs of scientific research.

[0004] However, the above components cannot effectively and fully ensure that the sample is not in contact with the outside world. In addition, because the high-temperature and high-pressure reactor has a high wall thickness ratio due to the high working pressure, the effects of methods such as low-temperature compressed air blowing and ice water soaking in the reactor are very low. Under methods such as high-temperature compressed air blowing and ice water soaking in the reactor, the pressure in the reactor changes with the cooling, which causes certain interference to the actual test, so it needs to be improved.
