The specific application embodiment of the utility model is as follows:
The pretreatment adopts a plate type washing tower 1 to filter and remove most of high-viscosity dust particles in the flue gas flow. The washing tower adopts S-shaped plate type packing and vortex spray heads, has higher anti-blocking performance, and has low cleaning frequency and cleaning operation intensity. The multistage plate type washing towers 1 are arranged in sequence, so that the washing cleaning frequency can be guaranteed. Finally, the waste water is filtered and removed step by a three-stage bag filter, and tiny particles and water mist particles which cannot be removed by washing are washed.
The washing liquid after the mutual contact heat exchange between the plate-type washing tower 1 and the flue gas returns to the circulating water tank 3, and the internal circulating cooling water of the cooling tower 6 passes through the heat exchanger 61 and returns to the circulating water tank 3 after the dividing wall type heat exchange.

Two groups of tubular heat exchangers 61 are arranged in the cooling tower 6, so that the cleaning of the air inlet of the tubular heat exchangers 61 is facilitated under the condition that the heat exchange efficiency is not affected.
The washed high-viscosity dust particles enter the air floatation integrated machine 4, and after the processes of dosing treatment, coagulation, carbon adsorption, flocculation and the like, the flocculate floating on the liquid surface is scraped off the liquid surface under the action of a scraper and enters the sludge concentration tank 33. The flocculate at the middle and lower layers enters the buffer tank along with water flow. The material in the buffer tank 42 is sent into the sand filter tank 41 for secondary mechanical filtration to remove the flocculate at the middle and lower layers entering the buffer tank, and the clarified liquid is returned into the clean water tank 32 in the circulating water tank 3.
