Performance of flue gas bleaching

Henan xinlianxin chemical fertilizer 3 * 180t boiler flue gas bleaching project

Release time: November 8, 2018 | Focus on: three thousand two hundred and eighteen

The 3 * 180t / h circulating fluidized bed boiler of Henan xinlianxin chemical fertilizer Co., Ltd. No. 4 branch is operated in two operation and one standby mode; the boiler adopts ammonia desulfurization technology, and is equipped with two desulfurization towers, one for operation and one for standby, and a set of wet electrostatic precipitator is set behind each desulfurization tower. At present, there is no purified water washing section in desulfurization tower. In this revamp, it is proposed to add a water washing section at the upper part of the desulfurization tower, and the cooling water washing liquid of the cooler is added, and the water washing liquid exchanges heat with the flue gas, so as to reduce the flue gas temperature of the desulfurization tower (below 47 ℃).

   When the temperature of purification section of heat exchanger is 42 ℃, the effect of flue gas is very obvious!

The length of flue gas decreases from about 200m
