Abstract
The invention discloses a desuperheating heating technique of spinning cases, which heats thermal medium through a thermal medium stove, transmits the high-temperature gassy thermal medium into a desuperheating device through pressure, sprays liquid condensate into the desuperheating device, controls the temperature inside the desuperheating device achieving the vapor and liquid balance by controlling the pressure of an outlet of the desuperheating device, distributes and transmits the thermal medium that achieves the vapor and liquid balance into a heated case, thus realizing heating. Incoagulable gas inside the heating case is exhausted through a vent pipe. The liquid condensate inside the heating case flows back to a low-position storage tank, and the pressure inside each heating unit is kept equal by ensuring the equality of the liquid level of each liquid condensate backflow pipe. The desuperheating heating technique of the spinning cases can directly use a large-scale thermal medium stove for heating the thermal medium, large amount of the thermal medium which is in vapor state can be transmitted by providing only pressure, and compared with original electric thermal medium heating techniques, the desuperheating heating technique of the spinning cases saves large amount of energy and lowers the production cost of enterprises.
