一种燃煤锅炉的脱硫废水处理装置
摘要：
本发明公开了一种燃煤锅炉的脱硫废水处理装置，属于废水处理技术领域。该处理装置包括锅炉、与锅炉相连接的空气预热器和电除尘器，空气预热器上还设置有空气预热器出口烟道，空气预热器出口烟道的总长度L1与空气预热器的长度L2之间的长度比为2～5:1。且通过空气预热器出口烟道将空气预热器与电除尘器相连；在空气预热器出口烟道的内部设有若干个均匀布置的喷枪，喷枪为具有双流体流动的喷枪，且喷枪的气体压力控制在0.05～0.15Mpa之间，喷枪的液体压力控制在0.1Mpa～0.5Mpa之间。该处理装置实现脱硫废水中水和杂质的分离，同时分离的杂质可以被回收利用，因此达到了经济环保的要求。
摘要（英）：

The invention discloses a desulfurization waste water treatment device of a coal-fired boiler, and belongs to the technical field of waste water treatment. The treatment device comprises the boiler, an air preheater and an electric duct collector. The air preheater and the electric dust collector are connected with the boiler. An air preheater outlet flue is further arranged on the air preheater, and the length ratio of the total length L1 of the air preheater outlet flue to the length L2 of the air preheater is (2-5):1. The air preheater and the electric duct collector are connected through the air preheater outlet flue. A plurality of evenly-distributed spraying guns are arranged in the air preheater outlet flue and are spraying guns with double liquid flowing, the gas pressure of the spraying guns is controlled to range from 0.05 Mpa to 0.15 Mpa, and the liquid pressure of the spraying guns is controlled to range from 0.1 Mpa to 0.5 Mpa. The treatment device achieves separation of water and impurities in desulfurization waste water, meanwhile, the separated impurities can be recycled, and therefore the requirement for economical efficiency and environment protection is met.
