Embodiment Construction
[0021] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0022] figure 1 A side view of the visible ignition and monitoring device for underground coal gasification of this embodiment is shown, figure 2 is its front view. Referring to the diagram, it can be seen that in order to judge the progress of the underground coal gasification ignition process more accurately and effectively, and even the progress of the gasification process, a video monitoring system 4 is added to the traditional ignition system 1 to realize the control of the ignition process. The real-time monitoring of the process and gasification process can not only improve the effective judgment of whether the ignition is successful, but also enable a more in-de...

The invention discloses an underground gasification visualized ignition and monitoring device of coal, comprising an ignition system arranged below a coal ground, a video monitoring system and a temperature measuring system which are located at one side of the ignition system, and a ground control system which is connected with the ignition system, the video monitoring system and the temperature measuring system; the video monitoring system can collect an ignition process image of the ignition system in real time; the temperature measuring system can detect a temperature of an ignition process; the collected image and temperature data are transmitted to the ground control system; and the ground control system controls the opening and the closing of the ignition system in real time, and the size of a fire behavior. The underground gasification visualized ignition and monitoring device of the coal can overcome the disadvantage that the traditional ignition device cannot monitor the ignition process on line and cannot directly display the ignition process; the deep understanding of the ignition process in a gasification process can be improved so that an ignition technology is further controlled and improved, so as to be adapted to the requirements of a specific coal layer; and meanwhile, the device can make right judgment on the ignition of the coal layer, the operation is simple and the method is safe and environment-friendly.
Description
technical field [0001] The invention relates to the related fields of underground coal gasification technology and comprehensive utilization of coal combustion, in particular to a visual ignition and monitoring device in the underground coal gasification process. Background technique [0002] Underground coal gasification technology is one of the fundamental ways to fundamentally solve a series of technical and environmental problems existing in traditional coal mining methods, and has been highly valued worldwide. It transforms the traditional physical coal mining method into a chemical coal mining method, which has the advantages of good safety, low investment, high efficiency, scientific and environmental protection, etc. Therefore, under the situation of energy crisis, the development of underground coal gasification technology, especially deep underground coal gasification technology, is of great significance for the efficient and comprehensive utilization of coal resou...
