Example Embodiment

[0056] Example 1:

[0057] See Figure 1-4 Coal fire treatment based on carbon dioxide process and modular design, including a heat source system for providing a heat source, the heat source system connected to a mobile power generation system for power generation; the heat source system includes underground coal fire 1 Plumb 6; the mobile power generation system includes four portions of the moving expansion portion 8, the moving boost portion 9, the mobile liquid carbon dioxide storage tank 10, and the mobile electrical energy storage unit. By adopting the above-described system, the side reactance of the carbon dioxide medium is sufficiently taken into account in the temperature of less than 500 ° C, which combines underground coal fire, carbon dioxide capture, modular movable, coal fire waste heat utilization, etc. The stability of the underground coal fire treatment process.

[0058] Further, the inner portion of the coal seam 5 contains a coal seam crack 2, and the upper laye...

Example Embodiment

[0064] Example 2:

[0065] A coal fire treatment utilization system based on carbon dioxide process and modular design, with mainly carbon dioxide flow, thermal flow, and electric energy flow three-strand quality flow during governance process. Among them, the carbon dioxide fluid passes through the moving expansion portion 8, the mobile liquid carbon dioxide tank 10, the moving boost portion 9, high temperature resistant high pressure liquid carbon dioxide transmission pipe 6, coal fire core area 1, gaseous carbon dioxide collection well 7, mobile type The system is sequentially connected to the system to complete the thermodynamic cycle of carbon dioxide power generation.

[0066] Further, based on the carbon dioxide process and modular design of coal fire treatment utilization system operating method, the system began to transport, the underground space constituted by the underground coal fire core region 1 and the coal seam fracture 2 maintained positive pressure, carbon dioxi...

Abstract

The invention relates to a coal fire treatment and utilization system and method based on a carbon dioxide process and modular design, and the system comprises a heat source system for providing a heat source, and the heat source system is connected with a mobile power generation system for power generation; the heat source system comprises an underground coal fire core area, the underground coal fire core area is located in the coal seam, a gaseous carbon dioxide collecting well is arranged at the position, communicated with the underground coal fire core area, in the coal seam, and a carbon dioxide conveying and distributing pipe is arranged on the side edge of the gaseous carbon dioxide collecting well; the movable type power generation system comprises a movable type expansion part, a movable type pressure boosting part, a movable type liquid carbon dioxide storage tank and a movable type electric energy storage part. The side reaction of a carbon dioxide medium when the temperature is lower than 500 DEG C in the underground coal fire spontaneous combustion process is fully considered, and the comprehensive functions of underground coal fire treatment, carbon dioxide capture, modularization mobility, coal fire waste heat utilization and the like are achieved.

Description

technical field [0001] The invention belongs to the field of coal mine security, in particular to a coal fire treatment and utilization system and method based on carbon dioxide technology and modular design. Background technique [0002] China is a big coal country, and 70% of our industry depends on coal resources. With the goal of carbon peaking and carbon neutrality proposed, the low emission and refined utilization of coal resources will be particularly important. Coal fire disasters occur widely in major coal producing areas around the world, which not only bring huge resource loss to our country and even the world, but also cause serious damage to the atmospheric environment. According to reports, my country directly loses 13.6 million tons of coal resources due to coal fires every year, and indirect losses of 200 million tons of coal resources due to inability to mine, and causes more than 35 million tons of carbon dioxide emissions. [0003] The existing treatment...
