Description

Sintering machine with gas and steam coupling

Technical Field

The invention relates to the technical field of sintering, in particular to a gas and steam coupled sintering machine.

Background

Sintering is a main raw material processing technology for iron and steel smelting in China, and more than 75% of blast furnace raw materials come from sintered ores.

At present, an ignition furnace is arranged at the head of a sintering machine, an ignition burner is installed in the ignition furnace, a sintering pallet is installed on the sintering machine in an end-to-end manner, wheels of the sintering pallet are installed on a sintering machine rail, and the sintering pallet runs along the sintering machine rail. The bottom air box is arranged below the sintering machine rail, the upper part of the air box corresponds to the bottom of the trolley, and the lower part of the air box is connected with a large sintering flue. The sintering of the device mainly utilizes the coal powder to burn and generate a large amount of heat, so that the energy consumption is higher and the emission pollution is heavier.

In view of the technical problems, a gas injection and steam injection reinforced sintering technology is provided, and the two technologies are relatively advanced green sintering modification technologies at the present stage.

Specifically, compared with the conventional sintering machine, the gas injection reinforced sintering technology is characterized in that a gas injection cover is additionally arranged on the upper part of a sintering machine trolley behind an ignition furnace, and a gas injection pipe is arranged in the gas injection cover. The gas injection technology is used for replacing part of coke powder added by sintering by injecting gas lower than the lower limit of gas explosion concentration into the surface of a sintering material layer after an ignition furnace, so that the gas enters the sintering material layer from the surface of the material layer and is combusted near the upper part of a combustion zone. The technology can effectively reduce the usage amount of the coke powder and the discharge amount of pollutants in the whole production process. In addition, the technology can also effectively avoid overhigh sintering peak temperature, prolong the high-temperature retention time of sintering and improve the quality of sintered ores.

In addition, in the steam injection sintering technique, a steam injection pipe is provided in an upper portion of a sintering pallet behind an ignition furnace, as compared with a conventional sintering machine. The steam injection technology is to inject steam on the surface of the sintering material layer, so that the steam passes through the upper part of the sintering material layer to be burnt into ore and then contacts with the coke powder in a burning zone to react, and the water gas reaction is utilized to play a role in strengthening the burning of the coke powder, so that the burning is more complete, the burning efficiency and the quality of the sintering ore are improved, and the using amount of the coke powder is reduced.

However, unburned gas sprayed by the gas injection technology can catch fire when meeting local high-temperature points of the charge level, and production safety and sintering effect are affected; and the steam sprayed by the steam spraying technology absorbs heat through water gas reaction, and is sprayed prematurely to influence the formation and sintering effect of a combustion zone.

Therefore, how to provide a gas-steam coupled sintering machine, which guarantees the sintering effect while realizing energy conservation, emission reduction and quality improvement, is a technical problem to be solved urgently in the field.
