Document Type and Number:
Japanese Patent JP2019211120
Kind Code:
A
Abstract:
To provide a cleaning and cooling method of exhaust gas capable of preventing damage of tower inner walls by performing maintenance of injection nozzles at appropriate timing, and a cleaning and cooling facility of exhaust gas.SOLUTION: In a cleaning and cooling method in a cleaning and cooling facility, exhaust gas exhausted from a smelter furnace is led to cleaning and cooling towers 2, 3, 4, cooled by being injected with cleaning and cooling water (circulated acid) through injection nozzles 20-3, ..., 40-4 in the cleaning and cooling towers 2, 3, 4 and impurities are removed at cleaning. Using a flow meter provided in a cleaning and cooling water piping (circulated acid piping) for supplying the cleaning and cooling water (circulated acid) to the injection nozzles 20-3, ..., 40-4, the variation of the flow rate of the cleaning and cooling water (circulated acid) injected from the injection nozzles 20-3, ..., 40-4 is measured and a cleaning and cooling state of the cleaning and cooling towers 2, 3, 4 can be monitored.SELECTED DRAWING: Figure 12
