Demisting water receiver and wet desulphurization tower

The invention provides a demisting water receiver. The demisting water receiver comprises a cooling water spraying pipe, a water receiving disc, a water receiving and demisting integrated disc and a demisting disc, the water receiving disc and the water receiving and demisting integrated disc are provided with water collecting tanks with upward openings, the water receiving and demisting integrated disc and the demisting disc are provided with demisting grooves with downward openings, and the cooling water spraying pipe, the water receiving disc, the water receiving and demisting integrated disc and the demisting disc are sequentially arranged from top to bottom in the airflow transmission direction. The demisting water receiver is arranged at an outlet of a wet desulphurization tower, andthe cooling water is sprayed through the top of the cooling water spraying pipe to condense and cool the flue gas, so that the white smoke is eliminated. The demisting tank can prevent desulfurization circulating slurry carr
