Air supply heating equipment based on coal mine air exhausting waste heat

Abstract

The invention discloses air supply heating equipment based on coal mine air exhausting waste heat, and belongs to the field of mine waste heat utilization. The equipment comprises an air exhausting pipe, an air supply pipe, an atomization back-flushing heat exchange structure, an automatic water storage and water treatment structure, a self-discharge dust treatment structure, an air outlet condensation structure, cooling fins, and a heat pump. The air exhausting pipe and the air supply pipe are adjacently arranged; the atomization back-flushing heat exchange structure is arranged in the air exhausting pipe; and atomized water is used for collecting sensible heat and latent heat of air in the air exhausting pipe. Water is purified through the automatic water storage and water treatment structure and then is circulated between the heat pump and the atomization back-flushing heat exchange structure, and heat exchange is realized; and then the air supply pipe is heated through the coolingfins, the air outlet condensation structure condenses exhausting air through external low-temperature air, water vapor in the exhausting air is condensed and falls back, the recycling of the water vapor is achieved, and automatic dust intercepting and discharging treatment is achieved through the self-discharging dust treatment structure.

Description

technical field [0001] The invention relates to the field of mine waste heat utilization, in particular to an air supply heating device based on the waste heat of coal mine exhaust air. Background technique [0002] China is the world's largest coal-producing country. Coal plays a dominant role in the energy structure, accounting for about 60% of primary energy consumption. In the traditional coal production process, coal mines need to be heated in winter. Or other heating methods for heating, consume a lot of energy. [0003] Mine exhaust is an important component of the mine ventilation system. Mine exhaust has a large air volume and high humidity. Existing mine exhaust air is usually discharged directly into the atmosphere. [0004] Mine exhaust air contains a large amount of sensible heat and latent heat. Therefore, it is possible to use mine exhaust air to heat the mine supply air to achieve ventilation and heating in the mine. There are a small amount of related equi...

Problems solved by technology

[0004] Mine exhaust air contains a large amount of sensible heat and latent heat. Therefore, it is possible to use mine exhaust air to heat the mine supply air to achieve ventilation and heating in the mine. There are a small amount of related equipment in the prior art, but it has the following problems. Mine exhaust air The dust content in the wind is relatively large, and the existing mine exhaust waste heat equipment cannot effectively treat the dust, which in turn causes the dust to accumulate in the pipeline, thereby affecting the operation of the equipment; Drenching causes high humidity in the mine exhaust air, and a large amount of water mist is discharged into the atmosphere, resulting in waste of water resources; the existing mine exhaust air utilization equipment is not convenient for backwashing the internal pipelines of the equipment, and the coal mine dust deposition during work is likely to cause pipeline damage. Congestion, which affects equipment operation
