A breaker of a bound furnace charge in a shaft furnace is cylindrical in shape, and two ends of the breaker are horizontally arranged on the furnace shell of the shaft furnace. The breaker is characterized in that the crusher is arranged below the central line of the inlet of the bustle tube of the shaft furnace, the lower surface of the crusher is a horizontal plane, and the bustle tube of the shaft furnace is communicated with a coal gas channel formed below the crusher through a coal gas branch tube II horizontally arranged on the wall of the furnace; and the upper portion of the crusher is an arc surface and is provided with crushing members, and the crushing members can rotate under the action of a driving apparatus. The crusher crushes a bound material formed in the reduction process of the furnace charge, improves the binding condition of the furnace charge, effectively introduces the reduced coal gas to the central zone of the shaft furnace through utilizing the coal gas channel ...

The invention discloses a direct reduction method for producing sponge iron by the aid of coke oven gas. The direct reduction method is characterized in that the coke oven gas which is purified and pressurized and vertical furnace top gas which is dedusted, cooled down and pressurized jointly enter a gas heating device to be heated, and then enter a low-pressure vertical furnace to reduce iron ore so as to produce the sponge iron. By the aid of catalysis of conversion reaction of the reduced fresh sponge iron in the low-pressure vertical furnace (with the pressure ranging from 0.1MPa to 0.2MPa) to CH4, CO2 and H2O and carburization reaction of the sponge iron and the CH4, the CH4 in the coke oven gas is converted and modified in the vertical furnace, so that CO and H2 are generated, and reduction gas lost in reduction reaction is supplemented. By the aid of the low-pressure vertical furnace, high-pressure equipment, high-pressure sealing and the like of a high-pressure vertical furnace ...

The invention discloses a method for producing direct reduction iron by the aid of coke oven gas. The method is characterized in that reduction gas at the temperature ranging from 1050 DEG C to 1200 DEG C is led into a vertical furnace to realize reduction reaction, cold coke oven gas leads to the bottom of the vertical furnace, rises from a cooling section on the lower portion of the vertical furnace, and then is mixed with the reduction gas, after the temperature of mixture of the cold coke oven gas and the reduction gas is reduced to be 900-1000 DEG C, the coke oven gas and the reduction gas jointly enter a reduction section of the vertical furnace, and accordingly reduction of iron ore is completed. The coke oven gas is used as the reduction gas and further is used as cold gas, two strands of coke oven gas are mixed at the bottom of the reduction section of the vertical furnace and are jointly reacted, energy conservation and emission reduction are realized, and investment to a cooling ...

The invention relates to a cooling method of a direct reduction vertical furnace which is characterized in that cooling gas is divided into two parts, and the two parts enter a cooling section; one part of the cooling gas enters the vertical furnace from the upper part of the cooling section; the part of cooling gas is heated by hot sponge iron when cooling the sponge iron, and participates in a reduction reaction in a reduction section; the other part of the cooling gas enters the vertical furnace from the lower part of the cooling section, and further cools the sponge iron; the part of cooling gas is led out through a cooling gas outlet pipe arranged in the middle part of the cooling section. According to the invention, cooling gas is divided into two parts, and two-stage cooling is adopted, such that high-temperature section sponge iron energy is fully utilized, circulation cooling gas is reduced, tuyere-section reduction coal gas inlet amount is reduced, reduction coal gas needed to ...
