Improvement practice of liquid supply method for overflow weir in flue gas purification system
In response to the problems of blockage and failure of the overflow weir ring pipe in the turbulent flushing tower,the liquid supply of the overflow weir is changed from the circulating acid pump in the turbulent flushing tower to the filtrate pump separately conveying the filtered clear liquid.The operational effects of the system before and after the renovation are analyzed and compared.The modified liquid supply method ensured sufficient,continuous,and stable liquid supply to the overflow weir,played a role in cooling and dust removal,effectively extended the service life of the reverse nozzle,reduced maintenance costs,and saved system operating costs.
