Abstract

The embodiment of the invention provides a bell-type furnace heating mantle gas system and an operation method thereof. The bell-type furnace heating mantle gas system comprises a gas pipeline and a bell-type furnace heating mantle, wherein the gas pipeline is communicated with the bell-type furnace heating mantle; and in the conveying direction of mixed gas, the gas pipeline is sequentially provided with a filtering device and a gas preheating mechanism, the filtering device is used for filtering dust in the mixed gas, and the gas preheating mechanism is used for preheating the filtered mixedgas. Dust in the mixed gas is filtered through the filtering device on the gas pipeline, and then the filtered mixed gas is preheated through the gas preheating mechanism, so that salt substances inthe mixed gas are in an aerosol state, and the probability of blockage caused by crystallization of the salt substances at places such as elbows, reducing parts and valves on the gas pipeline and thebell-type furnace heating cover, which cause the conductance change of the mixed gas, can be reduced. Meanwhile, naphthalene and tar are in an aerosol state, and the viscosity is reduced, so that theprobability of blockage caused by adhesion at a gas conductance change place can be reduced.

Description

technical field [0001] The present application relates to the field of steel coil production equipment, more specifically, to a heating hood gas system of a bell furnace and an operation method of the heating hood gas system of a bell furnace. Background technique [0002] The gas system of bell-type furnace heating hood includes gas pipeline, bell-type furnace heating hood and smoke exhaust pipeline. The gas pipeline burns the gas through the burner of bell-type furnace heating hood. After the coal gas is burned in the heating mantle of the bell-type furnace, the flue gas is exhausted from the exhaust pipe. The gas fed into the gas pipeline is mixed gas composed of blast furnace gas and coke oven gas. There is a large amount of dust, tar, naphthalene and salts (in the form of aerosol) in the mixed gas. These substances block the heating mantle pipeline and ancillary equipment (such as gas solenoid valves, manual valves, burners, reducing diameters and elbows) and affect t...
