Description
Technical field
The utility model relates to the central cooler apparatus field, relates in particular to circular cooler trolley top seal device.
Background technology
In steel manufacture process, the energy consumption of sintering circuit accounts for 10% of total energy consumption, is only second to the ironmaking operation, occupies second.In the sintering circuit total energy consumption, there is nearly 50% heat energy to enter atmosphere with the sensible heat form of sintering device flue gas and cooling machine waste gas.
For the call of respective country energy-saving and emission-reduction, the fume afterheat of sintering circular-cooler is recycled.The Sealing Technology of central cooler has influence on the effect that the fume afterheat of central cooler is recycled, and circular cooler trolley top seal device has accounted for very consequence in the Sealing Technology of whole central cooler.
In the central cooler equipment that metallurgy industry uses, the cold wind process circular cooler trolley comb plate heat of cooling sintering deposit that air blast blasts from bellows, cooling EGT later is 250-400 ℃, even higher.This waste gas produces steam by waste heat boiler after reclaiming, can be directly with or be used for cogeneration.Circular cooler trolley top seal device is vital, and it is related to waste heat recovery efficient.Existing circular cooler trolley top seal device such as Fig. 1, shown in Figure 2, the breast board of circular cooler trolley is covered by waste heat recovery cover 2, so that reclaim waste gas.Waste heat recovery cover 2 is hung on the central cooler skeleton 1 by suspension arrangement 4, and spacing by take-up device 5.Its seal is a block plate, and steel plate and chassis 3 sideboard end faces keep gap 5mm at least, because the chassis breast board moves, makes and installation errors in addition, and this gap is unsuitable too small.Because waste gas is constantly drawn from the waste heat recovery cover, cause to be negative pressure in the waste heat recovery cover, make a large amount of cold airs invade the waste heat recovery cover through the gap, cause EGT to reduce, waste heat recovery efficient reduces, and influences the output of steam, has caused energy dissipation.
The utility model content
The purpose of the utility model is the deficiency that overcomes prior art, and the circular cooler trolley top seal device of a kind of good airproof performance, long service life, easy maintenance is provided.
In order to solve the technical problem of above-mentioned existence, the technical scheme that the utility model adopts is following:
Circular cooler trolley top seal device; Comprise waste heat recovery cover, chassis; Chassis is provided with breast board; Also comprise spring sealed plate, waste heat recovery cover horizontal supporting plate, waste heat recovery cover gusset, spring sealed plate fixed head, chassis side seal matching board, chassis gusset, the said chassis two breast boards outside all is set with chassis side seal matching board, and each said chassis side seal matching board below is provided with the chassis gusset; The bottom of said waste heat recovery cover both sides outer wall is provided with waste heat recovery cover horizontal supporting plate; Said waste heat recovery cover horizontal supporting plate upside is provided with waste heat recovery cover gusset; The said waste heat recovery cover gusset outside is fixedly connected spring sealed plate fixed head; Said spring sealed plate fixed head is fixedly connected spring sealed plate, and said spring sealed plate and chassis side seal matching board seal each other.
The said chassis plate that is sealed and matched is positioned at the outer half side of chassis breast board upper end.
Said spring sealed plate fixed head is connected through bolt and nut with spring sealed plate.
Said spring sealed plate is a spring corrosion resistant plate material.
Said spring sealed plate one end is a bending.
Be bridging arrangement between the said spring sealed plate.
Compared with prior art, the beneficial effect of the utility model is:
Utilize the elasticity of spring corrosion resistant plate material self, the slit between waste heat recovery cover and chassis is sealed; Because the heat resisting temperature of spring corrosion resistant plate can reach 1000 ℃, reach at chassis top EGT under 400 ℃ the working environment and can use for a long time, and the elasticity of material self can not change owing to the work of long term high temperature environment; The spring corrosion resistant plate adopts the range upon range of mode of a slice a slice to utilize nut to fix, and very big convenience is provided for so later installation and maintenance.
