Specific embodiment
The present invention is described in further detail below in conjunction with attached drawing embodiment.
The present invention relates to a kind of industrial waste gas processing systems, mainly include flushing cinder tower 1, spray column 2, packed tower 3, sedimentation basin
4th, water cooling pond 5 and hot-tub 6, the bottom of the flushing cinder tower 1 are connected with electric furnace 7, and the outlet of flushing cinder tower 1 is immersed in sedimentation basin 4
Water in, cold water in the water cooling pond 5 is connected to the entry position of flushing cinder tower 1 by flushing pump 8, the tail generated to electric furnace 7
Gas is rinsed, and the outlet of the sedimentation basin 4 is connected with hot-tub 6, and hot water is driven into cold by hot-tub 6 by cooling pump 9
But tower 10 cools down, and the outlet of cooling tower 10 is connected with water cooling pond 5, and it is cold that the hot water in hot-tub by cooling pump is evacuated to cooling tower
But, the water to cool down enters water cooling pond, and the water of water cooling pond is used as rinsing, spray, cool down.Separating in the sedimentation basin 4 has
