Fault treatment method of dust remover valve for steelmaking system

Abstract

The invention discloses a fault treatment method of a dust remover valve for a steelmaking system, relates to the fields of steelmaking devices and processes, and provides a fault treatment method ofthe dust remover valve for the steelmaking system, which is used for still guaranteeing the normal running of the steelmaking system when the dust remover valve has a fault. The fault treatment methodof the dust remover valve for the steelmaking system comprises the following steps of, on a dust remover ash discharge pipe, arranging a temporary valve below the dust remover valve; when the dust remover valve has the fault, keeping the normal running of the steelmaking system, manually regulating the dust remover valve to be normally open, and starting and using the temporary valve. When the dust remover valve has the fault, the normal running of the steelmaking system is kept; the chain reaction can be prevented from being caused when the dust remover valve has the fault to cause the lanceaction and the smelting stop of a converter; the loss caused by the fault of the dust remover valve is avoided. When the dust remover valve has the fault, the temporary valve is started and used; theeffect of the dust remover valve can be fundamentally substituted, and not only is the ash discharge effect achieved, but also the air is furthest prevented from entering a dust remover to cause a venting explosion.

Description

technical field [0001] The invention relates to the field of steelmaking equipment and technology, in particular to a method for troubleshooting a valve of a dust collector in a steelmaking system. Background technique [0002] At present, a large amount of dust and high-temperature flue gas will be generated in the production of steelmaking converters, and the dry dust removal system is to cool the high-temperature flue gas, process the dust and recover the gas in the flue gas, so that the flue gas can meet the environmental protection discharge standard to discharge. The common failure of dry dust removal is the explosion venting of the electrostatic precipitator, which will cause the deformation of the cathode and anode plates of the electrostatic precipitator and affect the dust removal ability of the electric field. For this reason, on the basis of ensuring that the system is tightly sealed, the coarse and fine ash conveying systems are used in the dry dust removal sys...

Problems solved by technology

However, at present, double pendulum valves are frequently stuck, which can easily cause damage to the cylinder and abnormal limit detection. A little carelessness will cause abnormal operation of the double pendulum valves, thereby interlocking the lifting gun of the converter, causing the molten steel of this furnace to be soaked in the converter.
