Beschreibung
Zusammenfassung:	The invention relates to a special roof type evaporator for coal mine methane. The special roof type evaporator for the coal mine methane is that a mine ventilator is in sealing communication with a coal mine methane diffusion column through an air duct; an upper end outlet of the coal mine methane diffusion column is in sealing fixing with a lower end inlet of an evaporator; the evaporator body is in sealing communication with a channel of a coal mine methane source heat pump through a medium conveying pipe and a medium returning pipe; another channel of the coal mine methane source heat pump is in sealing communication with a user through a water inlet/ outlet pipe water pump. The special roof type evaporator for the coal mine methane is simple in structure, small in resistance, high in heat exchange efficiency, effectively overcomes the influences of high humidity, large air flow, large dust quantity and small pressure difference of a coal mine on the heat exchange efficiency, and is long in service life and convenient to maintain.
