Abstract

The invention relates to a fluoroplastic waste heat recycling and ultra-low emission integrated device which is located above a catalytic reaction area in a desulfurizing tower and below a demister. The fluoroplastic waste heat recycling and ultra-low emission integrated device comprises a heat exchanger used for carrying out smoke waste heat exchange and capturing dust, a water flushing assembly used for flushing the surface of the heat exchanger, and a water collecting assembly used for collecting waste water and dust falling down from the surface of the heat exchanger. The water flushing assembly and the water collecting assembly are located above and below the heat exchanger respectively. The heat exchanger is a fluoroplastic plate type heat exchanger with a water inlet and a water outlet. The water inlet is connected with a low-temperature demineralized water feed pump. The water outlet s connected with a boiler system or a heating system. Compared with the prior art, the fluoroplastic waste heat recycling and ultra-low emission integrated device has good smoke waste heat recycling performance and dust and mist removing performance, and the purpose of integration of waste heat recycle and ultra-low emission is achieved. The fluoroplastic waste heat recycling and ultra-low emission integrated device has the beneficial effects of being resistant to corrosion, stable, reliable, low in water consumption and the like.

Description

technical field [0001] The invention relates to a high-temperature flue gas recovery device, in particular to a fluoroplastic waste heat recovery and ultra-low emission integrated device used in tail desulfurization tower systems such as thermal power boilers, industrial kilns, and heating furnaces. Background technique [0002] my country's thermal power boilers, industrial kilns and heating furnaces are mostly coal-fired. On the one hand, either due to the purpose of protecting the safety of the equipment or due to the limitations of the equipment, the discharge temperature of the flue gas is still relatively high, resulting in a large waste of energy. On the other hand, harmful substances such as dust, acid dew, and gypsum particles in the flue gas are likely to cause corrosion at the tail of the boiler, and when discharged into the atmosphere, they will pollute the environment and seriously endanger human health. On September 12, 2014, the National Development and Refor...
