Electric furnace flue gas dust removal device capable of storing flue gas

Abstract

The invention provides an electric furnace flue gas dust removal device capable of storing flue gas. According to the electric furnace flue gas dust removal device, flue gas treatment can be effectively performed, moreover, the size of the equipment can be reduced, then the consumption of materials can be reduced, and the investment cost and the operation energy consumption can be reduced. The electric furnace flue gas dust removal device comprises an electric furnace, a furnace hole smoke discharging pipe, a water cooling flue, a combustion settling chamber, an air cooler and a booster fan which are connected in sequence, a roof cover is arranged above the electric furnace, moreover, a direct-discharge opening of the roof cover is connected with the booster fan and then is sequentially connected with a bag-type dust collector, a dust removal fan and a chimney, a safety valve is arranged between the roof cover and the bag-type dust remover, the electric furnace flue gas dust removal device further comprises a smoke storage fan, a bypass valve and a flue gas storage pipe, a bypass opening is formed in the roof cover, the bypass opening is connected with the flue gas storage pipe through the smoke storage fan, and the bypass valve is connected between the flue gas storage pipe and the direct-discharge opening.

Description

technical field [0001] The invention relates to the technical field of energy saving and environmental protection, in particular to an electric furnace flue gas dedusting device capable of storing flue gas. Background technique [0002] The existing steelmaking electric furnace flue gas dust removal system mainly consists of electric furnace, furnace hole exhaust pipe, water-cooled flue, combustion settling chamber, air cooler, booster fan, roof cover, safety valve, bag filter, dust removal fan, Generally speaking, the flue gas produced by the electric furnace during feeding and tapping is collected by the roof cover, and then filtered by a bag filter, and the filtered gas is discharged into the atmosphere through the exhaust chimney; The generated high-temperature flue gas is discharged from the exhaust pipe of the furnace hole. After cooling, it is mixed with the secondary flue gas collected by the roof cover, and then filtered by a bag filter. The filtered gas is discharg...
