Due to handled raw material be solid, mobility is bad, and melt after fused salt viscosity it is larger, feeding-passage angle of inclination compared with
It is small, therefore flow velocity is relatively low, molten salt furnace charging rate can be caused slow, treating capacity is low；
Nearby temperature is higher for solid salt charge door, and moisture and organic matter are contained in solid salt, and mobility is bad, is not easy to add
Material；
Solid salt melting process needs to absorb a large amount of heat, and the swept area for relying solely on loading channel is difficult by solid
Salt all melts, therefore it is solidliquid mixture to enter in furnace chamber.It is unfused since the density and surface tension of fuse salt are larger
Solid salt can swim in ullage, can by the overflow port on weir top flow into discharge port, cause organic matter removal endless
Entirely；
Flue-gas temperature after burning is higher, and 900 DEG C of ＞, flue gas is in direct contact with solid salt, the tiny solid salt in part
Grain can be taken out of with flue gas, and direct emission can cause energy waste and dust harzard.

Temperature is down to 300 DEG C or less and is discharged again by smoke outlet, while the industrial salt particle in flue gas is trapped in checker.
Kiln burning air used blasts air inlet by air blower, into another regenerative chamber, due to air themperature compared with
It is low, 200 DEG C are heated to by the indoor checker of accumulation of heat, subsequently into furnace chamber ontology, while will be left in the indoor industry of accumulation of heat
Salt particle is taken back in melt chamber.Two regenerative chamber alternate runs, it is primary every switching in 3 minutes, complete high-temperature flue gas and cold air
Heat exchange, improve energy utilization rate.
It is equipped with flue shutter between the regenerative chamber and smoke outlet, fortune is heated or cooled for switch two regenerative chambers
Row.
Solid industrial salt enters rectangle charge door by charger, into the melt chamber of furnace chamber ontology, is melted after being heated
Melting becomes liquid, and the organic matter in Nacl cracks at high operating temperatures, then by Flame of Natural Gas combustion decomposition.Liquid
Fused salt enters discharge port by unicom mouth, is then discharged out melting furnace.The high-temperature flue gas that melting furnace burning generates passes through one of them
Hot-air channel enters regenerative chamber, then passes through smoke outlet discharge system.Air enters from another checker regenerative chamber lower part
System, is heated to 200 DEG C, then enters melt chamber from hot-air channel when passing through regenerative chamber.
The advantageous effect that the utility model is reached is：
