System and method for removing pollutants in flue gas collected from sodium sulfide hot-melting tank

The invention relates to a system and a method for removing pollutants in flue gas collected from a sodium sulfide hot-melting tank. Flue gas collected from a sodium sulfide hot-melting tank is collected and then conveyed to a flue gas washing tower, a washing solution is in strong and sufficient contact with the flue gas in a reverse spray pipe of the washing tower, so that the pollutants in theflue gas are absorbed or dissolved by a circulating solution, the washed flue gas is sequentially subjected to settling separation in a gas-liquid separation area and inertia separation by a baffle plate and a compound baffle plate to remove particles (containing water drops and dust) entrained in the flue gas, so that clean emission of tail gas is realized. By adopting the method and the system provided by the invention, the pollutants in flue gas collected in the sodium sulfide hot-melting tank can be efficiently removed, the obvious defects of the traditional removal device are overcome, the field environment of so
