TECHNICAL FIELD

[0001] The utility model belongs to sewage treatment technical field, and specifically relates to be used for the suspended solid removal structure in dust removal circulating water. BACKGROUND

[0002] The heat conduction furnace tail gas dust removal generally adopts the water film dust removal method, so that the coal ash and smoke dust in the tail gas can be removed, and the tail gas can be discharged after cooling. In order to ensure that the smoke dust content in the discharged tail gas meets the standard, it is necessary to ensure that the circulating water is relatively clean. Therefore, the circulating water needs to be replaced frequently to ensure a certain degree of cleanliness. Frequently replacing the circulating water increases the consumption of water resources and the amount of wastewater treatment, and increases the cost of tail gas treatment. Therefore, it is necessary to treat the dust removal circulating water.
