Technical Field

[0001] The invention belongs to the technical field of coal mine waste heat utilization, and in particular relates to a coal mine waste heat comprehensive utilization system. Background Art

[0002] Comprehensive utilization of coal mine waste heat refers to the use of various technical means to convert coal mine waste heat into usable energy for heating, cooling, power generation, seawater desalination and other fields; Comprehensive utilization of coal mine waste heat has the following significant advantages: Energy saving: Coal mine waste heat is a valuable secondary energy source, which can reduce the use of fossil fuels and save energy. According to statistics, the annual waste heat of a large coal mine can be equivalent to hundreds of thousands of tons of standard coal. If it can be comprehensively utilized, a large amount of fossil fuels can be saved; Environmental protection: If coal mine waste heat cannot be effectively utilized, it will be directly discharged into the atmosphere, causing greenhouse gas emissions and environmental pollution. The comprehensive utilization of coal mine waste heat can reduce waste heat emissions and reduce environmental pollution; Promote economic benefits: The comprehensive utilization of coal mine waste heat can bring additional economic benefits to coal mines. For example, using coal mine waste heat for heating can reduce the cost of purchasing fuel; using coal mine waste heat for power generation can sell surplus electricity to the power grid.

[0003] A large amount of waste heat is generated in the coal mine production process, including wind exhaust waste heat, water gushing waste heat, etc., but the coal mine waste heat contains a large amount of impurities. Among them, wind exhaust waste heat contains a large amount of suspended particles such as mine dust, and water gushing waste heat contains a large amount of suspended matter, heavy metals and other pollutants. When the wind exhaust waste heat, water gushing waste heat and other coal mine waste heat are directly used, impurities will accumulate in the pipeline, which will not only affect the normal use of coal mine waste heat, but also impurities will easily corrode the pipeline. Long-term use will easily damage the pipeline, leading to leakage of coal mine waste heat, causing serious pollution to external water bodies, air, etc., resulting in serious consequences. The Chinese patent application publication number CN112360585A discloses a system for comprehensive utilization of waste heat from coal mines, including a heat recovery component, an air-to-air heat exchanger, an air-circulating water heat exchange component, a cooling water component, an air heat source component, a natural gas boiler component, a water source heat pump, a steam-water heat exchanger, a bathing heat exchanger, a wellhead fresh air unit and a dry fresh air component. The natural gas boiler component includes a hot water type natural gas boiler and a steam type natural gas boiler. The dry fresh air component includes a cold air unit and a first electric heating unit connected in sequence. The system for comprehensive utilization of waste heat from coal mines provided by the invention selects the utilization method of waste heat according to the specific situation in coal mine operations, and can fully utilize the waste heat. By utilizing abundant waste heat resources such as energy supply equipment, exhaust air, cooling water, etc., the equipment has high safety, can realize the cascade utilization of energy, significantly improve the comprehensive utilization rate of energy, achieve the goal of energy conservation and emission reduction, and at the same time ensure the stability of energy consumption in the mining area; the system for comprehensive utilization of coal mine waste heat can realize the utilization of coal mine waste heat, but because the exhaust air waste heat of coal mines contains a large amount of suspended particles such as mine dust, and the gushing water waste heat contains a large amount of suspended matter, heavy metals and other pollutants, the presence of these impurities will not only affect the recovery and utilization of coal mine waste heat, but also easily corrode the pipeline, resulting in leakage after the pipeline is damaged, causing serious pollution to the external water and air, thereby causing serious consequences.
