Sintering device, sintering cooler and its flexible sealing device

Abstract

The invention discloses a sintering machine or a sintering cooler and a flexible seal equipment thereof, which can reduce the power consumption of blowers, decrease the air leakage of the equipment, increase the waste heat recovery efficiency and improve the environment. The sintering cooler comprises a sinter-loading trolley, an overhead hood above the trolley, a bellows below the trolley, an upper flexible seal device arranged between the hood and the upper part of the trolley, and a lower flexible seal device or a lower lamination seal device arranged between the lower part of the trolley and the bellows; wherein, the slideway of the bellows is glidingly contacted with a flexible slide plate of the trolley; the upper flexible seal device is used to seal the gap between the hood and theupper part of the trolley; and the lower flexible seal device or the lower lamination seal device is used to seal the gap between the lower part of the trolley and the bellows.

Description

technical field [0001] The invention relates to a sealing device of metallurgical equipment, in particular to a sintering machine, a sintering cooling machine and flexible sealing devices thereof. Background technique [0002] In metallurgical production, the sintering machine is used to sinter ore powder into sintered ore, and the sintered ore is cooled to below 150°C by the sintering cooler, and then sent to the smelting process. Sinter production is an important process in steel production, and it is also a process that consumes a lot of energy. [0003] Sintering coolers are mainly divided into two types of cooling methods: draft cooling and blast cooling, and from the structural type, there are mainly two types of belt coolers and ring coolers. [0004] The sectional view of the sintering cooler is shown in figure 1 , see side view figure 2 ,From figure 1 , figure 2 It can be seen that between the trolley 4 and the bellows 6, between the trolley 4 and the fume ho...

AI Technical Summary

Problems solved by technology

Because the pressure inside the bellows is greater than the external pressure, the air leaked at B is at normal temperature; the air leaked at A is at medium temperature (about 350°C), and the air leaked at A will also bring out a large amount of dust, which will cause thermal pollution. Dust pollution will be caused; cross air (internal leakage) between the fume hoods will be formed at C. Because the temperature of the hot flue gas in the 1# fume hood 21 and the 2# fume hood 22 is different, generally the difference is about 150°C, and the 1# fume hood The hot flue gas in 21 is generally connected to the waste heat boiler for waste heat recovery, and the waste heat boiler produces steam for production or domestic use. If the flue gas in 1# fume hood 21 is strung into 2# fume hood 22, the waste heat utilization will be effective The air volume is reduced. If the flue gas in the hood 22 of 2# enters the hood 21 of 1#, the temperature of the flue gas in the hood 21 of 1# will be lowered. thus adversely affecting waste heat recovery
