Gas cleaning of steam power plant and heat utilization system

The utility model discloses a gas cleaning of steam power plant and heat utilization system, including secondary cold wind draught fan, air heater, boiler, wet desulphurization tower, zero release desulphurization waste water treatment system and chimney, through the position and the relation of connection of each equipment of reasonable layout, the energy consumption has been practiced thrift tothe used heat of make full use of boiler exhaust flue gas, has improved flue gas waste heat utilization. Additionally, the utility model discloses a merge and use membrane distillation technology anddense water evaporation crystallization process for the characteristics that waste liquid pollution index is low of discharging. Through heating wet desulphurization tower exhaust low temperature fluegas utilization boiler used heat, the flue gas after the messenger mixes is higher than the dew point of water, and the flue gas of emission satisfies national flue gas emission standard. 本实用新型公开了种热电厂烟气净化及热能利用系统，包括二次冷风引风机、空气预热
