Heat collecting heat exchange system and heat collecting heat exchange method for worked-out section

Abstract

The invention discloses a heat collecting heat exchange system and a heat collecting heat exchange method for a worked-out section. The heat collecting heat exchange system for the worked-out sectioncomprises a worked-out water collecting area, a water storage pond and a heat pump, wherein the worked-out water collecting area is arranged in the worked-out area for storing water for obtaining heatenergy, and a water collecting inlet and a water collecting outlet are formed in the worked-out water collecting area; the water collecting inlet and the water collecting outlet communicate through afirst circulating pipeline of a first circulating pump; a water storage inlet and a water storage outlet are formed in the water storage pond, and the water storage inlet and the water storage outletcommunicate through a second circulating pipeline of a second circulating pump; the second circulating pipeline is used for providing heat to a to-be-heated device; and the heat pump device arrangedunderground comprises an evaporating end and a condensing end; and the evaporating end is used for exchanging heat with the first circulating pipeline and the condensing end is used for exchanging heat with the second circulating pipeline. According to the heat collecting heat exchange system and the heat collecting heat exchange method for the worked-out section, the heat use ratio is improved and the energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of coal mining, and more specifically, to a goaf heat collection and heat exchange system and a heat collection and heat exchange method. Background technique [0002] With the development of society and economy, my country's energy demand has been on the rise. For a long period of time in the future, it will not be possible to reduce the dependence on fossil energy. In particular, the proportion of coal consumption in energy consumption will remain high. The degree of pressure on renewable resources and the pressure on environmental capacity will seriously restrict social and economic development. It is of great significance to make full use of renewable energy and reduce dependence on fossil energy. The country attaches great importance to the development and utilization of geothermal heat, especially the development and utilization of shallow geothermal heat, and has been widely promoted in northern region...

AI Technical Summary

Problems solved by technology

Due to the large area of ​​the mine goaf, its geothermal development potential is also great, but the heat source of the exhaust air and the drainage of the mine cannot bring the geothermal heat contained in the goaf out of the ground, and the heat source of the goaf has not been developed and utilized.
