Description

Изобретение относитс к горному делу, а более конкретно к обогреву шахтных стволов и охлаждению возду-ха в выработках глубоких угольных шахт. В насто щее.врем вентил ционный воздух, подавае1 й в ствол шахты , предварительно подогреваетс до. температуры , чтобы не допустить обмерзани стенок. . The invention relates to mining, and more specifically to the heating of mine shafts and cooling air in the workings of deep coal mines. At present, the ventilation air supplied to the shaft is preheated to. temperatures to prevent frosting of the walls. .

Claims

30 that a device for heating the shaft and cooling the mine workings, containing heaters and heat pipes connected to them; 1 temperature sensors, the outputs of which are connected to the inputs of the amplifier converting element, the output of which is connected to a control panel installed on the inlet pipe conductor, supplied with drift heat receivers with cladding agent and drift pipelines with energy carrier, circulation pumps, pressure reducer, stem pipelines attached to the heat receiver. energoyositelem and connected in parallel thereto, and a refrigeration unit dopolnitelnELMi ka loriferami, wherein the first temperature sensor is mounted in the ambient air, the second - in the energy carrier, as the barrel and shtrekovye conduit connected to the energy source with a pressure reducer and a circulating pump. The drawing shows a device for heating the shaft shaft and cooling the mine workings, a general view. The device has an air heating unit 1 containing main heaters 2 and additional heaters 3, refrigeration unit 4, pressure reducer 5, interconnected by trunk pipe of energy carrier b, with pressure transmitter 5 being connected with energy carrier 7, on which circular pipes are mounted A pump 8 is connected to heat receivers 9, consisting of individual sealed hollow panels 10, inside of which cooling pipes 11 pass, connected to a drip pipeline. 7. m; The coolant to the heaters 2 is led through the inlet pipe 12. Its flow rate is controlled by the control unit 13 consisting of a control valve 14 electrically connected through an amplifier-transforming element 15 with a sensor 16 for the energy carrier 16 and an outdoor temperature sensor 17. The device works as follows. The air-heating unit 1 receives heat for additional heating heaters 3 from heat collectors 9 installed on a deep horizon, tightly adjacent to the surface of mine workings and performing simultaneously the function of arch support. Heat receivers 9, partially filled with refrigerant, such as refrigerant 12, perceive the heat of rocks. Under the action of heat leakage, the refrigerant in the panels 10 boils and its vapors condense on the cooling pipes 11 running inside the panels 10. The heat of condensation is transferred to the energy carrier passing through pipelines 11. The heated energy carrier through the drift pipes 7 is supplied to pressure reducer 5, further The pipelines of the stem circuit 6 are supplied to the additional heating heaters 3, where they are cooled with fresh air. After that, the pipelines of the barrel 6 drift circuit return to the heat collectors 9. In the air-heating installation, air is heated in series in the heaters 2 and in the additional heating heater 3, the total heat output of the air-heating installation 1 is provided by supplying the required amount of heat carrier from the boiler and uncontrolled heat transfer rocks. The supply of heat from the mine boiler house is regulated by the control and regulation unit 13, consisting of a control valve 14, electrically connected via an amplifying and converting element 15 with temperature sensors 16 and 17; installed on the pipeline energy carrier stem contour biv flow of external air entering the air-heating installation; 1. Air-heating installation 1 in winter operates in two modes: during the cold period they work, heaters 2 and. additional heating heaters 3 | during the transition period - additional heating heaters 3. In the warm period, the pipelines of the stem circuit b are connected only to the refrigeration unit 4. The proposed device, along with the utilization of the heat to heat the ventilation air, prevents the heat of the rocks from entering the mine workings and produces cooling moreover, it allows reducing the heat consumption for heating the ventilation air of the main heat consumer by 5-6%, which provides a significant economic effect.
