Embodiment 1

[0041] refer to Figure 1-7 , which is the first embodiment of the present invention, provides a direct heating device using an abandoned mine, which includes a pipe assembly 1, a connection assembly 2, a protection assembly 3, a fixing assembly 4, a water pump 5 and a plate heat exchanger 6. Wherein, the connection assembly 2 includes a flange seat 21, a flange head 22 and a fastener 23, the flange seat 21 and the flange head 22 are respectively arranged at both ends of the pipe assembly 1, and the end surfaces of the two can cooperate with each other, The fastener 23 connects the flange seat 21 and the flange head 22 in one body; the pipe assembly 1 includes a steel pipe 11, a hose 12 and a conduit 13, all of which can be connected to each other through the connection assembly 2 provided at the end. 11 is bidirectionally distributed in the shaft of the mine, while the hose 12 is distributed in the shaft and roadway of the mine, one end of which is connected to the end of the...

Embodiment 2

[0052] Different from Embodiment 1, the construction method for the direct heating device includes the following construction steps:

[0053] S1: scheme design, design a complete heating scheme according to the heating demand and the heat supply of the mine;

[0054] S2: For specific construction, the steel pipe 11 is installed, and the pipes are arranged vertically and bidirectionally along the inner wall of the shaft, divided into water inlet pipes and water outlet pipes, and fixed by U-shaped rods 41;

[0055] S3: hose installation, the vertical part of the hose 12 on the inner wall of the shaft needs to be installed first, and the buoyancy air bag 32 and the U-shaped soft rod 42 are arranged in sequence;

[0056] S4: Select two groups of roadways located at different depths, and check the area where the hose 12 is laid in the roadway, and remove obstacles;

[0057] S5: After the investigation and cleaning are completed, a sand cushion 31 is installed at the bottom of the ...

Abstract

The invention discloses a direct heating device utilizing an abandoned mine shaft, which includes a pipe assembly, a connection assembly, a protection assembly, a fixing assembly, a water pump and a plate heat exchanger, wherein the connection assembly includes a flange seat, a flange head and a fastening The flange seat and the flange head are respectively arranged at both ends of the pipe assembly, and the end faces of the two can cooperate with each other, and the fastener connects the flange seat and the flange head in one; the pipe assembly includes steel pipes, hoses and conduits, The three can be connected with each other through the connecting components provided at the ends. The steel pipes are distributed in the shaft of the mine in both directions, and the hoses are distributed in the shafts and roadways of the mine. One end of them is connected to the end of the steel pipes. The outside of the mine is connected to a water pump and a plate heat exchanger in sequence, and the two ends of the heat exchanger are respectively connected to the top of bidirectionally distributed steel pipes; the invention not only has a good heating effect, is convenient for construction, has little impact on the environment, and has high applicability.

Description

technical field [0001] The invention relates to the technical field of mine heating, in particular to a direct heating device using an abandoned mine and a construction method thereof. Background technique [0002] With the in-depth mining of mineral resources and countries choosing to phase out traditional fossil energy due to ecological and environmental problems, a large number of underground roadways and chambers have been abandoned. According to statistics, the number of abandoned mines worldwide exceeds 1 million. Abandoned mines cause waste of resources and bring serious environmental and social problems. Therefore, how to scientifically develop and utilize abandoned mine resources and promote the transformation of resource-exhausted mining areas has become an important issue in the field of energy and environment in the world today. Due to the depth of the mine, the geothermal energy resources contained in it are also abundant. Therefore, how to use these geothermal...
