Kerosene vapor-phase drying equipment
Kerosene vapor-phase drying equipment (KVPD) is mainly suitable for drying transformer bodies in super-high voltage than 110kV and big capacity.
Working Principle
Under heating and vacuum condition, liquid kerosene will become vapor in high temperature. When vapor meets workpieces in less temperature, it will condense and release latent heat of condensation (about 306.6kJ/kg) which will heat workpieces. Condensed kerosene will be collected and re-transmitted to the evaporator to be heated again. In this way, under several cycles, temperature of workpiece increases continuously and moisture inside the workpieces evaporate to water vapor, to be taken out by vacuum and thus achieve complete drying on the workpieces.
