一种复合污染物脱除工艺及装置
摘要：
本发明公开了一种复合污染物脱除工艺，包括如下步骤：1)喷淋吸收净化步骤；2)管式预除雾步骤；3)湿式电除尘净化步骤。另外本发明还提供一种实现上述复合污染物脱除工艺的复合污染物脱除装置，包括脱除塔，脱除塔的下部设有烟气进口，脱除塔的上部设有烟气出口，在脱除塔中位于烟气进口与烟气出口之间从下至上依次设有脱硫喷淋层、管式除雾器和电除尘器，位于烟气进口下方还设有储存石灰石浆液的浆液池。本发明将三个工艺步骤集中于一个脱除塔内，省去了传统脱硫塔中的顶部除雾器，高效去除PM2.5微尘和SO3酸雾气溶胶并有效避免“石膏雨”现象。
摘要（英）：

The invention discloses a process for removing combined pollutants. The process for removing the combined pollutants comprises the following steps of: 1) spraying, adsorbing and purifying; 2) carrying out tubular pre-defogging; and 3) carrying out wet electric dedusting for purifying. In addition, the invention also provides a device for removing the combined pollutants for implementing the process for removing the combined pollutants, wherein the device for removing the combined pollutants comprises a removal tower of which the bottom is provided with a smoke inlet and the top is provided with a smoke outlet, a desulfurization spraying layer, a tubular defogger and an electric dust catcher are orderly arranged between the smoke inlet and the smoke outlet from bottom to top in the removal tower, and a slurry pond for storing limestone slurry is arranged under the smoke inlet. According to the invention, three process steps are integrated in one removal tower, so that a top defogger in the traditional desulfurizing tower is omitted, PM2.5 tiny dust and SO3 acid mist aerosol are removed efficiently and a 'gypsum rain' phenomenon is avoided effectively.
