Abstract
The utility model discloses a novel ignition system for the blast furnace gas sintering machine, comprising a cooler, a waste air fan housing, a warm air pipeline, a warm air pressing blower, a gas pipeline, and an igniter. The waste air fan housing is arranged on the cooler, connected with the input terminal of the warm air pressing blower through the warm air pipeline; the output terminal of the warm air pressing blower is connected with the igniter through a pipeline; simultaneously, the gas pipeline is connected with the igniter; warm air exhausted from the cooler enters the igniter together with the gas conveyed through the gas pipeline passing through the waste air fan housing, the warm air pipeline, and a warm air dust collector after being pressed through the warm air pressing blower. The utility model uses the waste warm air exhausted by a sintering device cooler as the ignition-supporting air of the igniter and the heat sources of the preheating section and the thermal insulation section, the heat exhausted by the equipment is throughly used, the structure of the equipment is simplified, and the operation for the equipment is more convenient.
Description
Technical field
The utility model patent relates to a kind ofly to be used in agglomeration for iron mine technology, is used for the ignition system of compound igniting on the sintering pallet.
Background technology
There is the use blast furnace gas of two kinds of structural shapes to make the ignition of sintering process device of fuel in the prior art.A kind of is to establish one or two heating furnace on the ground, behind the combustion air and BF gas heating of the usefulness of will lighting a fire respectively, delivers to combustion air and the fuel of igniter as igniter.Another kind is on sintering pallet, establishes a heating furnace behind the igniter, and the combustion air heating of earlier igniter being used is given igniter then and done combustion air.The shortcoming of prior art is: the equipment complex fuels consumes high inconvenient operation.
The utility model content
At the deficiencies in the prior art, the purpose of the utility model patent is to provide a kind of equipment simple, use hot waste gas that the sintering machine cooler discharges as the igniter combustion air, and produce at blast furnace and can use the ignition of sintering process system of other fuel when undesired as igniter fuel.
For achieving the above object, this novel blast-furnace coal gas ignition of sintering process system comprises cooler, waste gas fan housing, hot air duct, hot blast booster fan, gas piping, igniter, the waste gas fan housing is arranged on the cooler, the waste gas fan housing links to each other with hot blast booster fan input through hot air duct, hot blast booster fan output links to each other with igniter through pipeline, gas piping links to each other with igniter simultaneously, the hot blast of discharging from cooler is through waste gas fan housing, hot air duct, and through hot blast booster fan pressurization back and from the coal gas of gas pipeline transportation service inlet point firearm together.
Further, also be provided with the hot blast deduster on the hot-air channel that constitutes by cooler, waste gas fan housing, hot air duct and hot blast booster fan.
Further, described ignition of sintering process device comprises igniting section, soaking zone, and soaking zone is positioned at igniting section rear portion.
Further, described ignition of sintering process device also comprises preheating section, and it is anterior that this preheating section is positioned at described igniting section.
Further, described soaking zone, preheating section all use the hot blast of drawing from cooler as thermal source.
Further, a described igniting section top is provided with at least one row's coal gas burner.
Further, also be provided with other fuel nozzle on the two side of described igniter igniting section.
The utility model utilizes waste hot gas that the sintering machine cooler the discharges thermal source as preheating section and soaking zone in the combustion air of igniter and the igniter, has both made full use of the heat that equipment is discharged, and has simplified device structure again, makes equipment more convenient to operate.
