INSTALLATION FOR INVESTIGATING PROCESS OF INTERACTION OF EXPLOSIVE AND/OR TOXIC AND/OR CHEMICALLY AGGRESSIVE GASES WITH METALS, ALLOYS AND MATERIALS Russian patent published in 2024 - IPC G01N25/00 

FIELD: measurement.

SUBSTANCE: invention relates to experimental study of physical and chemical properties of metals, alloys and materials, specifically to the technique of determining the rate of interaction of explosive, and/or toxic, and/or chemically aggressive gases with metals, alloys and materials in a wide range of temperatures and can be used in materials science, chemical, oil and gas, nuclear, aerospace and machine building industries. Installation for investigating the process of interaction of explosive, and/or toxic, and/or chemically aggressive gases with metals, alloys and materials contains a system for measuring weight of the sample, which includes an analytical balance for continuous weighing of the sample, a movable furnace for heating the sample, which is installed with possibility of being pulled onto the reactor, inside which there is a vertical holder with a cuvette for the analysed sample, a system for supplying and dosing gases, and a temperature measurement sensor. Additionally, the gas supply and dosing system includes a buffer tank for the analysed gases, having a pressure equal to the gas pressure in the reactor, sample weight measurement system includes a device which allows to periodically remove the load from the balance to compensate for the zero drift of the analytical balance, wherein additionally introduced is a system for removing gas from the reaction zone, which includes an explosive gas concentration sensor, fan forcing air into the gas-air mixture discharge vent channel to reduce gas concentration below its explosive limit in air, as well as a toxic gas neutraliser.

EFFECT: expansion of the possibility of safe and accurate determination of the rate of interaction of explosive, and/or toxic, and/or chemically aggressive gases, their mixtures with metals, alloys and materials in a wide range of temperatures, increased accuracy of weight measurements, as well as elimination of reduction of pressure of reaction gas, which occurs during interaction of gas with sample with sharp increase in rate of absorption of sample of analysed gas in reactor.
