Technical Field

[0001] This utility model relates to the field of spray treatment technology, specifically to a spray treatment device for incinerator tail gas. Background Technology

[0002] A utility model patent with patent authorization announcement number CN207525004U discloses a desalination device for waste alkaline liquid after acid removal by spraying incinerator tail gas. The device includes a high-salt water storage tank, a metering pump, a heater, an evaporator, a circulating pump, a stirred crystallizing pot, a centrifuge, and a condenser. The bottom of the high-salt water storage tank is connected to the metering pump via a pipe, the metering pump is connected to the heater via a pipe, the top of the heater is connected to the evaporator via a pipe, the evaporator is connected to the stirred crystallizing pot via a pipe, and the stirred crystallizing pot is connected to the centrifuge. High-concentration brine (greater than 3%) in the high-salt water storage tank is pumped to the heater and heated to boiling point. The condensate produced in the condenser is treated with sodium hydroxide and reused for acid removal, then circulated back to the deacidification tower. The liquid in the evaporator is cooled and crystallized in the stirred crystallizing pot and then centrifuged and dried to produce crystalline salt as the finished product. The salt is recovered as a resource, reducing production costs, avoiding pollution from direct discharge, and the distilled salt can be recycled, thus saving resources.
