technical field

The utility model relates to the technical field of distilled water preparation, in particular to a novel circulating distilled water device.

Background technique

The current distilled water preparation usually adopts the method of evaporation and condensation, but the traditional preparation method has the following defects: 1. Waste of cooling water: the distilled water devices commonly used in the laboratory cannot reuse the hot cooling water after cooling down capacity, only a very small part of the cooling water produced by cooling the steam is returned to the evaporator for reuse; it is calculated that the utilization rate of tap water for the distilled water maker currently used in the laboratory is about 1% to 2%, resulting in a large number of The waste of water resources also increases the production cost; 2. The problem of water intake: the water distiller is often affected by the pressure change of tap water and the power supply status during the work process, making the water intake unstable; Due to the limitation, the distillation takes a long time, and it is impossible to be guarded during the whole preparation process. Therefore, when the flow rate of the incoming water becomes small or the water is cut off suddenly, if the control is not given in time, the water level in the distilled water evaporator will drop rapidly. Make the heater burn out, and even damage the whole equipment in severe cases; 3. Safety issues: the outer wall of the evaporating pot of the current water distiller has no heat insulation device, and the outer wall of the pot is very hot during the distillation process, and it is easy to burn the operator during the experiment , especially the hands. At the same time, due to the generation of a large amount of heat radiation, heat loss is caused, which increases the consumption of electric energy.
