Embodiment Construction

[0010] The principle is to add an appropriate amount of water vapor to the air of the burning sinter, and a water gas reaction will occur on the combustion layer to generate hydrogen and carbon monoxide, which will strengthen the reducing atmosphere of the combustion layer, which is more conducive to the reduction of iron, thereby reducing the sintering rate. iron oxide. At the same time, because the water-gas reaction is an endothermic reaction, the burned sinter is cooled rapidly, and the thermal conductivity of water vapor is dozens of times that of air, which naturally facilitates the cooling of sinter.

[0011] by figure 1 (Exhaust type) belt-type sintering machine is taken as an example. In the figure, a protective cover (14) and a blast control device (15) are installed from the igniter (2). The atomizing nozzle (10) and the electric atomizing nozzle (10) are adjusted by the thermal sensor (9) to control the switch. Under normal conditions, the temperature of the therm...

Abstract

The invention discloses an auxiliary device of a sintering machine. The auxiliary device can be a water gas generating device additionally arranged on the sintering machine. The auxiliary device is characterized in that a protective cover, an air supply control system, a pipeline, spray nozzles, valves and sensors are mounted in an area starting from an igniter of the sintering machine, steam can be distributed from the igniter of the sintering machine to the tail of the area, an appropriate amount of steam is added into air around combusting sintering ores, gas water reaction is carried out on a combustion layer, hydrogen and carbon monoxide are generated, reducing atmosphere of the combustion layer is strengthened, iron can be reduced advantageously, and accordingly iron oxide of the sintering ores is reduced. The auxiliary device of the sintering machine has the advantages that by the aid of the auxiliary device, the sintering ores can be directly cooled on the machine and can be conveyed in place, equipment (such as a belt cooler) which is high in energy consumption and investment can be omitted, the mechanization is improved, the labor intensity of workers is relieved, the auxiliary device is simple in process and is environmental friendly, energy can be saved, large quantities of resources are saved, and the like.

Description

Technical field: [0001] The invention relates to the metallurgical industry, and can also be said to be a water gas generating device on a sintering machine, especially a device that can reduce the iron oxide of sintered ore by 4 percent, and directly cool the sintered ore on the machine, which is convenient for transportation, environmentally friendly and energy-saving. Background technique: [0002] At present, there are two known cooling methods for sintered ore. One is natural cooling of hot mines, and the other is forced cooling. The hot ore is cooled naturally, the economic benefit is low, and the degree of mechanization is poor. The forced cooling of hot ore is divided into two types: zonal cooling and ring cooling, both of which are forced cooling by centrifugal fans. [0003] Taking belt cooling as an example, the sintering machine is 60m 2 , The daily production of sinter is about 2200 tons, and the cooling system is cooled by four 200kw centrifugal fans, the tr...
