Apparatus for removing the impurities from the pipe for the cokes oven gas

摘要

PURPOSE: An apparatus for removing impurities from piping for coke oven gas is provided which prevents damage of controller for regenerative burners and prevents fuel consumption by effectively removing impurities of iron oxide contained in the coke oven gas so that pure coke oven gas is supplied to the regenerative burners. CONSTITUTION: In an apparatus installed at a piping for supplying coke oven gas to regenerative burners of heating furnace in such a way that a fluid is communicated between the piping and the apparatus so as to remove impurities of iron oxide, the apparatus(20) comprises a hollow housing(21) installed on an upper part of the apparatus in such a manner that a cover(22) is separable from the housing; and a plural magnetic rods(23) installed on a lower surface of the cover, wherein impurities of iron oxide contained in coke oven gas passing through a hollow part of the hollow housing are adhered to the magnetic rods, and the impurities are removed by separating the cover from the hollow housing, thereby cleaning magnetic rods exposed, wherein the apparatus further comprises a differential pressure meter(30) installed at the hollow housing to detect a hydraulic pressure difference between an inflow part into which coke oven gas is flown and a discharge part from which the flown in coke oven gas is discharged, and wherein the apparatus further comprises a water supply pipe installed at the side wall of the hollow housing, and a drain pipe(29) installed at a lower part of the hollow housing.
