The invention provides an energy-saving boiler and a
thallium removal process for
spodumene brine. Relates to the field of energy-saving boilers. The furnace body is fixedly mounted at the bottom of the inner wall of the isolation box through a bracket; and the top cover is fixedly mounted at the top of the furnace body. According to the energy-saving boiler and the
spodumene brine
thallium removal process provided by the invention, water is injected into the boiler body by arranging the
water delivery pump, and external high-temperature
flue gas sequentially flows through the plurality of heating pipes, so that layered and stepped uniform heating of the
water body in the boiler body is realized, the
heat energy utilization efficiency is remarkably improved, and the energy is saved;
smoke flows step by step in the heating
pipe and is finally discharged, the flow speed of the
smoke is reduced, heat is fully exchanged, the
smoke discharging temperature is reduced, meanwhile, the water suction pump continuously and stably outputs hot water at the constant temperature of 40 DEG C to the constant-temperature water bath, stability of the
water supply temperature is guaranteed, operation is energy-saving, and the
automation degree is high.
