Abstract

The invention discloses a device for rapidly and automatically detecting the CO2 content of a heated propellant in an air environment. The device comprises a tank body, a cap cover, a cooling pipe, a heating furnace, a gas production device and a gas chromatograph, wherein a propellant is filled into the tank body, the cap cover is screwed down, air exhaust detection can be directly carried out after heating at 90 DEG C for 3 hours, and the gas in the tank flows through the cooling pipe and is injected into the gas chromatograph by a gas sucking pump through a Swagelok quick joint, so that the content of CO2 in the gas can be detected. According to the device, the post-cooling time of sample heating is shortened, and the detection time is shortened; and manual operation errors are reduced through automatic sampling, and the accuracy of a detection result is improved.

Description

technical field [0001] The invention belongs to the field of gas quantitative detection, and mainly relates to a rapid and automatic detection device for the pyrolysis gas content of propellants, in particular to CO in the pyrolysis gas of single-base propellants. 2 Rapid and automatic detection of content. Background technique [0002] Propellant is one of the energy sources for the launch of gun projectiles, and it plays a certain role in gun weapons. [0003] The propellant has the characteristics of "long-term storage and one-time use", and must have good stability. The stability of propellant is mainly chemical stability, which refers to the ability to delay decomposition and prevent automatic chemical changes during the storage period. Propellants contain nitrate compounds such as nitrocellulose, which contain nitrate groups and can decompose slowly by themselves. The gaseous decomposition products (such as NO 2 , NO, water vapor and HNO 3 ) has a catalytic effect ...
