[0002] Only steam is needed on equipment that uses steam, and this kind of heat-using equipment will definitely produce condensed water during heat exchange. The condensed water will absorb steam energy and reduce the steam quality, reduce the steam thermal enthalpy value and thus reduce the heat exchange rate. The condensed water becomes a harmful fluid and is also mixed with air and other non-condensable gases, which becomes the cause of equipment failure and reduced performance.

[0003] Condensate dischargers generally use the phase change nozzle vapor-liquid two-phase flow condensation principle to condense the vapor-liquid mixture produced by the consumption of steam heat energy after the heat-using equipment performs work through steam heat exchange (heat use) through the phase change nozzle into liquid condensate, which is quickly discharged to reduce the loss of steam heat energy. In general, the discharged condensate has a fluctuation range. Due to changes in steam supply quality, pressure, heat exchange efficiency of heat-using equipment, process conditions, etc., the amount of discharged condensate is unstable. Most existing phase change nozzles are fixed flow type, and the inability to adjust their flow in a targeted manner will affect accurate drainage and heat energy loss. Utility Model Content
