Abstract

The invention discloses a capsule-type heat energy extraction device and method in a coal field fire area, which belongs to the technical field of thermoelectric conversion equipment, and solves the problems of low heat energy utilization rate, low thermoelectric conversion efficiency, large engineering quantity, and difficult recovery and repetition in the prior art. use etc. The device of the present invention comprises a thermoelectric power generation device, a heat transfer device and a cooling device; the thermoelectric power generation device forms a hollow columnar structure, the cold end (81) is inside the columnar structure, and the hot end (82) is outside the columnar structure; the heat transfer device is used to increase heat end (82), the heat transfer device includes a high thermal conductivity capsule (11) and a medium temperature heat pipe (9); the cooling device is used to reduce the temperature of the cold end (81), and the cooling device includes a high thermal conductivity capsule heat pipe (5) and cooling fins (2). The device and method of the invention are suitable for heat energy extraction in coal field fire areas.

Description

technical field [0001] The invention belongs to the technical field of thermoelectric conversion equipment, and in particular relates to a capsule-type heat energy extraction device and method in a coal field fire area. Background technique [0002] Coalfield fire is one of the common disasters faced by coal mining countries in the world. Coalfield fire areas not only burn a large amount of coal resources and sluggish a large amount of coal resources cannot be exploited, but also produce a large amount of CO, CO 2 , SO 2 Toxic and harmful gases such as mercury, selenium and other harmful chemicals that pollute soil and water resources have caused serious damage to the fragile ecological environment in the west. [0003] Coalfield fire area has large combustion volume and high temperature, and huge heat is stored in the fire area. According to statistics, about 1 billion tons of coal are burned by underground coal fires around the world every year, generating about 1000GW ...
