Sintering device, sintering cooler and its suspension sealing device

Abstract

The invention discloses a sintering cooler and a suspended 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 plurality of sinter-loading trolleys, a plurality of overhead hoods above the trolleys, bellows below the trolleys, as well as suspended seal devices between every two adjacent hoods on the trolleys; wherein, the slideway of each bellows is glidingly contacted with a flexible slide plate of the corresponding trolley; the upper ends of the suspended seal devices are suspended on the combination part of two adjacent hoods; and the lower ends of the suspended seal devices are overhung on the sinter on the trolleys.

Description

technical field [0001] The invention relates to a sealing device for metallurgical equipment, in particular to a sintering machine, a sintering cooling machine and a suspension type sealing device 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 Fig. 1, and the side view is shown in Fig. figure 2 , from Figure 1, figure 2 It can be seen that between the trolley 4 and the bellows 6, between the tr...

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
