Dry, and enter deduster 4 with flue gas；(6) electric anion and flue dust occur electrostatic to react, and make flue dust carry out pre electrified,
Promote flue dust cohesion；(7) in waste water, inorganic salts and dust are removed in deduster 4, and waste water is logical in the form of purifying vapor
Cross deduster 4, subsequently into desulphurization system 1；(8) waste water that desulphurization system 1 produces is circulated through above-mentioned steps, reaches de-
Sulphur system wastewater zero discharge.Desulfurization wastewater directly passes through to filter, is sprayed in flue and dries, and the dust of generation is gone by deduster
Remove, vapor returns desulphurization system.Due to not being chemically treated to desulfurization wastewater, waste water, the acidity of waste gas can gradually increase
Height, the equipment of ultimately resulting in cannot run or operating efficiency is low；" the larger waste water of the sub- body of eddy flow 21 bottom solid content is through underflow
Mouth 25 discharge, and desulphurization system 1 of flowing automatically back ", is easily caused desulphurization system 1 and blocks, impact equipment normally runs；Ultrasonic atomization sprays
Mouth 3 sprays at the inlet flue duct 41 of deduster 4 after being atomized waste water, flue dust condenses the bulky grain ash of formation in the flue herein
Dirt sinks it is impossible to be collected by deduster 4, lacks corresponding flue dust collecting equipment, is easily caused flue blockage；The waste water of atomization is in cigarette
Dried by high-temperature flue gas in road, drying efficiency has much room for improvement.
