Mine waste heat cascade utilization integrated system

Abstract

The invention discloses a mine waste heat cascade utilization integrated system. The mine waste heat cascade utilization integrated system comprises a mine deep waste heat utilization system and a mine shallow waste heat utilization system. The mine deep waste heat utilization system comprises a power supply system and a hot water supply system. The power supply system comprises a deep waste heatpipe collecting system, a first heat exchanger and a power generating system which are connected in sequence, and the first heat exchanger and the power supply system are both connected with the hot water supply system. The mine shallow waste heat utilization system comprises a water heating and cooling system and a fresh air treatment system. The water heating and cooling system includes a buriedpipe, a heat pump unit and a floor radiant pipe system. Both ends of the buried pipe and both ends of a floor radiant pipe are separately connected with the heat pump unit, and the interior of a house is connected with the fresh air treatment system. The heat pump unit and the power generating system are both connected with the heat water supply system. The mine waste heat cascade utilization integrated system utilizes the waste heat of a mine by different level to realize the maximum utilization of the waste heat; and reduction the heat damage of the mine is achieved, energy saving and environmental protection are achieved, and the structure is simple.

Description

technical field [0001] The invention belongs to the technical field of mine waste heat utilization, and in particular relates to an integrated system for cascaded utilization of mine waste heat. Background technique [0002] Due to long-term mining, shallow resources are becoming increasingly exhausted, and most coal mines have entered the state of deep mining. Deep high-temperature heat damage is a common problem faced by deep mines, and the thermal environment of mines has increasingly become an important factor restricting the effective mining of deep deposits. Existing mine cooling technology is not well integrated with the utilization of geothermal resources; on the other hand, there are many problems in indoor comfortable environment adjustment, such as complex heating and cooling systems, relatively large energy consumption, loud noise, and unsatisfactory comfort. Traditional heating methods lead to environmental problems such as smog and dust, which makes it particu...

Problems solved by technology

Existing mine cooling technology is not well integrated with geothermal resource utilization; on the other hand, there are many problems in indoor comfortable environment adjustment, such as complex heating and cooling systems, relatively large energy consumption, loud noise, and unsatisfactory comfort

Traditional heating methods lead to environmental problems such as smog and dust, which makes it particularly necessary to study new energy sources and optimize existing indoor heating and cooling systems. The multi-generation system is being explored and applied, and needs to be further improved

The utilization of existing geothermal resources mostly adopts U-shaped wells and uses water for heat transfer, which has problems such as serious heat dissipation and large water demand, more heat utilization in shallow layers and waste in deep layers, and most of them are transported in the form of heat for direct use. low heat efficiency
