Problems solved by technology
[0005] The technical problem to be solved by the present invention is to provide a research device for material corrosion behavior in a hydrothermal system and its reactor to solve the problem of poor test accuracy due to the fact that the current material test piece is easily affected by various metal materials in the reactor. As well as the inability of the existing corrosion research technology to characterize and describe the corrosion environment of materials in detail, the restriction relationship between the corrosion behavior of materials and the environment is not clear, and there are certain limitations in revealing the corrosion process and control mechanism of materials. Difficult technical issues

Embodiment Construction
[0060] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the connotation of the present invention, so the present invention is not limited by the specific implementations disclosed below.
[0061] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected ...

The invention discloses a reaction kettle for a hydrothermal system reaction. The reaction kettle comprises: a kettle body, which has a reaction chamber, wherein a material inlet is formed in the lower portion of the kettle body; a kettle cover, which is detachably fixed onto the kettle body and is provided with a material outlet; a hanging rod, wherein two ends of the hanging rod are respectivelyfixed in the reaction chamber by fixing units, and hanging material pieces to be studied are arranged on the hanging rod in a sleeving manner; and a spacer ring, which is arranged on the hanging rodin a sleeving manner and configured to fix and separate adjacent hanging material pieces. The reaction kettle of the invention can make the corrosion environment of material test pieces simpler, avoids possible influence on determination due to existence of excessive metal materials in a hydrothermal oxidation system, and allows study results to be more accurate. The invention also discloses an apparatus for studying the corrosion behavior of materials in a hydrothermal system.
Description
technical field [0001] The invention relates to a research device for material corrosion behavior in a hydrothermal system and a reaction kettle thereof, in particular to research on corrosion performance of materials under the condition of hydrothermal oxidation of pollutants at a certain temperature and pressure, and belongs to the field of environmental equipment. Background technique [0002] The use of hydrothermal oxidation technology to treat pollutants not only has obvious advantages such as fast reaction speed, complete degradation, and no secondary pollution, but also can be integrated with other technologies to improve the efficiency of pollutant resource utilization and the effect of advanced treatment. However, the hydrothermal oxidation system of pollutants is in a state of high temperature, high pressure and strong oxidation. Moreover, with the progress of the degradation reaction, the heteroatoms contained in the pollutants are transformed into the correspond...
