the flue gas after primary purification and separation exchanges heat with the superheater (6), the air preheater (8) and the economizer (9), the temperature of the flue gas after heat exchange is reduced, solid particles in the flue gas are deposited in the conical cavity, and the solid particles are discharged to the slag bin (103) from a slag discharge port at the bottom of the conical cavity (300) through a slag discharge pipeline II (12);
the air preheater heats the cold air extracted by the primary air blower and then conveys the cold air to a primary air chamber (104), and the primary air chamber provides primary air for the fire grate;
the air preheater heats cold air extracted by the secondary air blower and then conveys the heated cold air to the hearth (102) to provide secondary air for the hearth;
the cooled and purified flue gas enters a deacidification reaction tower (4) for deacidification; the deacidified flue gas enters a cyclone separator II for secondary separation and purification; and after secondary separation and purification, the waste water enters a dust remover to be finally purified and dedusted, and the purified and dedusted waste water is discharged from a chimney after passing through denitration equipment.
