Abstract

The invention discloses a chromatographic analysis and index optimization determinator for a coal bed spontaneous combustion mark gas. The chromatographic analysis and index optimization determinator comprises a temperature control box, wherein a coal sample tank is arranged in the temperature control box; a gas inlet pipe is arranged at the bottom of the coal sample tank; the gas inlet pipe is connected with a gas intake system arranged outside the temperature control box; a gas delivery pipe of the gas intake system is connected with a preheating tube after entering the temperature control box; the preheating tube is connected with the gas inlet pipe; a gas outlet pipe is arranged at the upper part of the coal sample tank and connected with a gas chromatographic instrument; a temperature sensor I for detecting the temperature in the coal sample tank is mounted on the coal sample tank in an inserting manner; a temperature sensor II is arranged in the temperature control box; and the temperature sensor I and the temperature sensor II are connected with a controller; and the controller is used for controlling the temperature in the temperature control box according to the detected temperature, and simultaneously monitors and records temperature changes of the temperature control box and the coal sample tank.

Description

technical field [0001] The invention relates to a device for measuring coal seam spontaneous combustion marker gas, in particular to a measuring device for chromatographic analysis and index optimization of coal seam spontaneous combustion marker gas. Background technique [0002] Spontaneous combustion of coal seams is a natural disaster that seriously threatens the safety of coal mines. The flame and high temperature produced by spontaneous combustion of coal seams not only directly cause harm to people and equipment, but may also cause gas and coal dust explosions, further aggravate and expand the disaster, and cause serious damage to production equipment, production environment and coal resources. The spontaneous combustion of coal is a slow oxidation process. With the development of the oxidation process, a series of gases that reflect the spontaneous combustion characteristics of coal will be produced. As the temperature increases, the production of various gases chan...
