Abstract

The invention provides a heating system utilizing a mine ventilation air methane air energy heat pump. The heating system comprises a mine ventilation air methane duct communicated with a mine ventilation air methane outlet, a fresh air duct parallel to the mine ventilation air methane duct and a gravity heat pipe arranged between the mine ventilation air methane duct and the fresh air duct. The gravity heat pipe comprises a heat pipe evaporation section arranged in the mine ventilation air methane duct, a heat pipe condensation section arranged between the fresh air ducts and a heat pipe heat insulation section connected with the heat pipe evaporation section and the heat pipe condensation section; an interval space is arranged between the mine ventilation air flue and the fresh air flue; the heat pipe heat insulation section is arranged in the interval space formed by the mine ventilation air methane air duct and the fresh air duct. The mine ventilation air methane air energy utilization device has the advantages of being reasonable in design, saving investment, reducing energy consumption and fully utilizing mine ventilation air methane air energy.

Description

technical field [0001] The invention relates to a heat pump heating system utilizing exhaust air in a mine, and relates to the technical field of heat pumps for heating, ventilating and air conditioning. Background technique [0002] Mine culvert ventilation is a necessary prerequisite to ensure safety during coal mine production. Ventilation is an important link in mining. Article 137 of the 2016 edition of my country's "Coal Mine Safety Regulations" stipulates that the air temperature below the air inlet shaft must be above 2°C. Therefore, when the outdoor temperature is lower than 2°C, it is necessary to heat the incoming air of the mine and send it into the mine; [0003] As we all know, air energy heat pump technology belongs to the category of renewable energy, its energy saving is obvious to all, and its energy efficient heating capacity is greatly affected by the ambient temperature. If the exhaust air in the mine itself is not recycled and the heat is directly abso...
