Preferred further, liquid outlet connects solidifying water pot by pipeline.Improve material evaporation effect.
Preferred further, material spraying hole arranges multiple, and the cumulative area of material spraying hole is equal with the sectional area of the first pipeline.
The beneficial effect that the utility model has is:
1, tube still heater bringing-up section is sleeved in vaporizer by the utility model, two ends bobbin carriage is only had to be exposed among air, the shell making heater not with atmosphere, thus can not outwardly dispel the heat, in evaporation process, also fully employ the shell side of tube still heater, make its also one of area becoming heating, given full play to the usefulness of equipment, reduce hot loss of energy, improve energy-conservation effect.
2, gas-liquid separator is arranged on vaporizer inner top by the utility model, also isolate with ambient atmosphere, block the heat radiation of gas-liquid separator to air, decrease energy loss, and because the vapor (steam) temperature just evaporated is higher, relatively improve heat pump outlet steam temperature, also improve the heat-transfer intensity to evaporation process.
