Magnesium chloride evaporation device

The invention relates to a magnesium chloride evaporation device, which belongs to brine evaporation equipment. The magnesium chloride evaporation device includes a heating furnace. The heating furnace is connected with an evaporation supply tank and a heating evaporation tank through a pipeline. The heating pipe is connected to the bottom of the evaporation supply tank through a supply pipe, and the heating evaporation tank and the evaporation supply tank are connected through a steam communication pipe. There is a steam chamber, which can heat the brine of the heating evaporation tank. The setting of the steam chamber enables the heating evaporation tank to make secondary use of the steam thermal energy of the evaporation supply tank. The heated area of the brine improves the utilization of thermal energy.
