Product features:

(1) The low-temperature flue gas exchanger in the system driven by low-temperature flue gas to realize zero discharge of wastewater uses the gravity phase change principle to make it have high heat transfer efficiency and strong corrosion resistance.

(2) Titanium plate evaporator is used for multi-effect evaporation, which has efficient heat transfer effect and corrosion resistance.

(3) Flue gas in front of the desulfurizing tower is cooled, so that the effect of water saving is realized.

(4) Additional steam is not required to be introduced, energy saving, the investment cost is low, and the running cost is low.

Product description:

In the traditional process, the evaporation of desulfurization wastewater needs to consume a large amount of steam, the running cost is high, the desulfurization wastewater is highly corrosive, the chloride ion concentration is high, the reuse path is limited, and the investment and running cost of wastewater zero discharge project treatment is high, which has always been the difficulty of wastewater zero discharge project. A high-efficiency low-temperature flue gas heat exchanger is designed in the system, and a high thermal conductivity tube material made from low-dimensional carbon-based composite material is adopted, so that the temperature of the flue gas before entering the desulfurizing tower can be reduced from 150 ℃ to 80 ℃, the waste heat of the flue gas is used for heating the condensate to produce saturated steam of ~100 ℃, and the steam is used as a heat source to realize the effect of zero discharge of the wastewater of the desulfurizing tower through multi-effect evaporation and concentration of the desulfurization wastewater.
