Description
Technical field
This utility model is related to blast furnace process field, particularly to a kind of two-part agglomerates of sintered pellets chiller.
Background technology
Steel works sintering scale progressively expands, and leads to the yield of sintering deposit to increase sharply, because blast furnace is wanted to sintering deposit
Seeking Truth room temperature is it is therefore necessary to cool down to heat sinter.The sintering deposit cooling of existing domestic steel industry mostly adopts following
Three kinds of types of cooling: one is flat cooling, two is belt cooling, and three is annular cooling.The common work of these types of cooling is former
Manage and be: high-temperature material cools down in closed containing cavity, carry out heat exchange with cooling air-flow, the heat of material is taken away by gas.
Central cooler is common equipment, and its cooling means is to intersect cooling, there is cooling terminal, in central cooler traffic direction
On, flue-gas temperature is more and more lower, and central cooler is revolving body, and high temperature makes central cooler deflection big, and sand seal or water seal were easily lost efficacy,
This will lead to central cooler seal structure complex, manufacturing cost and cost of equipment maintenance very high it is difficult to promote the use of.For example middle promulgated by the State Council
Bright patent cn 101957146 a proposes " a kind of sealing device for annular cooling machine ", and this patented technology is to adopt in sintering ore cooling device
With the method for water-stop although can guarantee that certain sealing function, but cannot ensure that chiller high negative pressure operates, because high
Negative pressure can make sealing device lose efficacy.
Because existing heat sinter carrier (such as car, groove) is kept in motion, the chiller of existing heat sinter
The whole seal of heat sinter cooling procedure usually cannot be effectively ensured, this allows for sintering deposit cooling procedure and actually exists
Carry out in semi-hermetic or wide-open environment, in order to ensure cooling effect has to increase cooling air quantity, thus bring two
Individual problem, one is the high energy consumption of blower fan, and two is that pathogenic wind-warm after heat exchange is relatively low, and waste heat recovery is worth low, leads to sintering deposit first
Pick up the heat rate is not high.Such as Chinese utility model patent cn 203451587 u proposes a kind of " a kind of vertical cooling kiln ",
This patented technology in kiln body centrally disposed center blast cap, for cooling down high-temperature material.Due to the differing greatly of material particular diameter (0～
