Technical Field

The invention belongs to the technical field of coal mine equipment, and particularly relates to a device for adjusting the inlet air temperature of a coal mine port.

Background

The safety regulation of coal mines stipulates the air temperature of a mine, the air temperature below an air inlet well head must be more than 2 ℃, so that the air entering an air inlet main channel of the coal mine needs to be heated in winter, and at the present stage, the coal mine air inlet well is heated mainly by using a hot blast stove, but the coal combustion of a boiler is serious in pollution, the energy consumption is high, and the cost is high.

Some modified mines adopt a heat pump technology to recover low-temperature waste heat of mine return air to heat an air inlet well, and the application modes of recovering the low-temperature waste heat of the mine return air through a water and air source heat pump technology are mainly classified into a circulating spray type and a direct evaporation type at present, wherein the circulating spray type is that a spray tower is arranged at a return air inlet, the mine return air and the water are in direct contact for heat exchange, and the low-temperature heat energy is promoted and applied through the heat pump technology; the direct evaporation type air return port needs to be modified, a roof type color steel structure is arranged, evaporators are directly arranged on two sides of the steel structure, and the mine return air is forced to pass through the gaps of fins of the evaporators.

The water (wind) source heat pump system is an application technology in the field of energy conservation, although the water (wind) source heat pump system is popularized to some extent in recent years. But the technology has the following problems while saving energy and protecting environment: firstly, the system equipment has high cost, and civil engineering projects such as various circulating water pumps, various water treatment equipment, matched pipelines and other valve parts, electrical and control equipment, large machine rooms, pools and the like are required to be configured besides the core equipment heat pump main body; secondly, the operation cost is high, the heat pump system has more power consumption equipment, and various circulating water pumps, well mouth anti-freezing fans and the like are arranged outside the heat pump main body; thirdly, the management difficulty is higher, the number of operation equipment in the system is large, the failure rate is relatively high, and if heat exchange elements such as a surface cooler are easily frozen once power failure is found out untimely, the safety production is influenced, and the maintenance cost is higher.

Furthermore, the flat plate collector is a photo-thermal photovoltaic array collector.

Furthermore, a hot return air inlet of the hot return air channel is connected with a diffusion tower. The return air in the mine is introduced into the hot return air channel through the diffusion tower.

The invention has the beneficial effects that: the return air in the mine is introduced into a return air channel, a heat pipe in the return air channel absorbs the heat in the return air and transfers the heat to a cold fresh air channel, and the cooled return air is discharged from a return air outlet of the return air channel; the cold fresh air inlet of the cold fresh air channel sucks fresh air in the atmosphere, and the fresh air absorbs heat emitted by the heat pipe when passing through the channel and is discharged from the cold fresh air outlet into the underground, so that the inlet air temperature is improved; when the waste heat of return air in a mine is insufficient, the flat plate collector absorbs solar energy, and the heat reservoir stores media heated by the flat plate collector, so that enough heat energy is provided for fresh air when the waste heat of the return air is insufficient; the solar battery pack generates electric energy to drive the brushless direct current water pump, so that the normal operation of the system is ensured, and the energy consumption is greatly reduced.

The invention only needs to transfer the heat in the flat plate collector to the heat reservoir, and the rest works without consuming external energy, thereby saving energy, realizing the reutilization of energy, reducing the pollution to the environment, rapidly absorbing the heat in the return air in time through the heat pipe and transferring the heat to the cold fresh air channel, and simultaneously supplementing the heat by using the heat stored in the heat reservoir when the waste heat of the return air is insufficient, and ensuring the improvement of the temperature of the inlet air.
