Problems solved by technology

[0004] But the above-mentioned device also has the following problems. First, when the gas is supervised, a large amount of dust will be produced due to gasification, and the existing gas extracted when the gas is supervised will contain a large amount of dust or impurities, which will affect the extraction. The accuracy of gas monitoring, secondly, when gas is detected, the gas can only be monitored at a single position, which will cause inaccurate monitoring and affect the subsequent gasification of coal

Abstract

The invention discloses a coal underground gasification monitoring device, and belongs to the technical field of coal gasification, the coal underground gasification monitoring device comprises a mounting rack, a position displacement monitoring component, a dust cleaning monitoring component and a gas gasification monitoring component, the position displacement monitoring component is located on the mounting rack, and the dust cleaning monitoring component is located at the telescopic end of the position displacement monitoring component; the dust cleaning monitoring component comprises a mounting cylinder, a gas swing assembly and a dust blocking assembly, the mounting cylinder is connected with the telescopic end of the dust cleaning monitoring component, the gas swing assembly is located at the bottom of the mounting cylinder, and the dust blocking assembly is located in the mounting cylinder and is in sliding fit with the mounting cylinder; and the gas gasification monitoring component is located in the position displacement monitoring component and communicates with the mounting cylinder. According to the invention, gas in supervision gas is filtered through the gas swing assembly and the dust blocking assembly, so that accurate supervision data can be obtained.

Description

technical field [0001] The invention relates to the technical field of coal gasification, in particular to an underground coal gasification monitoring device. Background technique [0002] Underground Coal Gasification (Underground Coal Gasification) is a process in which underground coal is burned in a controlled manner and combustible gas is generated through thermal and chemical effects on coal. During the implementation of underground coal gasification, gasification agent and water or water vapor need to be injected, and the water or water vapor is used to react with hot coal seam to generate hydrogen and carbon monoxide. [0003] For example, the publication number CN107339092A patent relates to an underground coal gasification monitoring system. The system includes: a first measurement and control device and a second measurement and control device; wherein, the first measurement and control device is arranged between the gasification agent storage tank and the air int...
