[ background of the invention ]
In order to relieve the current situation of water resource shortage, part of coal-fired units begin to recover water in flue gas, and mainly recover water in flue gas at the outlet of a desulfurizing tower. Most of the water in the flue gas at the outlet of the desulfurizing tower is the desulfurizing process water evaporated from the flue gas, and the rest is the moisture generated by coal combustion. The water condensed from the flue gas usually carries a certain amount of dissolved salts and pollutants, and the water can be used for desulfurization process water through simple treatment, but is limited by the water balance of a desulfurization system, and most of the water still needs to be treated more strictly to be utilized, so that the water in the flue gas needs to be sampled and tested before the cooling water taking project is implemented to better utilize the recovered water, and an accurate treatment scheme is formulated. However, no smoke moisture sampling device for the purpose is available in the market at present.
