Embodiment
The invention will be further described with reference to embodiments, and purpose, which is only that, more fully understands present invention.Cause
This, the cited case is not limited the scope of the invention.
Referring to Fig. 1, this utilization salt quenching waste heat that the present embodiment is provided realizes the device of salt, Water Sproading, mainly by cold
Condenser 12 and heat exchanging evaporator are constituted, and heat exchanging evaporator is arranged on the top of quenching salt bath 15, housing 3 entirely through its housing 3
Bottom is communicated with quenching salt bath 15；An evaporation cavity 8 and a high temperature melting salt bath 4 are arranged in juxtaposition in the housing 3 of heat exchanging evaporator,
Be layering 20 evaporating pans 5 from bottom to top in evaporation cavity 8, and each evaporating pan 5 is both provided with one end and high temperature melting salt bath 4
Together with high-temperature molten salt import 6 and one end stretch out evaporation cavity 8 outside cooling after fused salt export 15；The upper end of high temperature melting salt bath 4
High-temperature molten salt overfall 7 is provided with, lower end passes through high-temperature molten salt input channel 2 and the high temperature salt pump 1 being placed in quenching salt bath 16
Connection.
The top of condenser 12 is with the top of evaporation cavity 8 together with the bottom of condenser 12 is provided with Rinsing Area 14, and condenser 12 is distinguished
It is provided with the low temperature strong brine entrance 13 attracted from cleaning machine and the brine outlet 11 preheated after heat exchange, brine outlet
