Description
Technical field
The present invention relates to Converter Residual Heat Boiler, and in particular to a kind of Converter Residual Heat Boiler movable gas hood.
Background technology
Coal gas, high temperature when Converter Residual Heat Boiler generally use gasification cooling flue structure is to iron and steel enterprise's Converter Oxigen Blowing steel-making
Flue gas and flue dust carry out waste heat recovery, and it is directly chain with the production process of converter, and the part as converter steelmaking process is straight
Participation STEELMAKING PRODUCTION is connect, it can collect high-temperature flue gas during converter smelting steel, and high-temperature flue gas is cooled down,
Meet the steel-making later stage dedusting and requirement of coal-gas recovering, while substantial amounts of steam can also be produced, for the needs for producing and living,
The cost of production and life can be substantially reduced, occupies highly important status in steel mill.Converter Residual Heat Boiler mainly includes living
Dynamic petticoat pipe, fire door fix petticoat pipe, hypomere cooling stack and epimere cooling stack.Due to Converter Residual Heat Boiler operating condition with turn
The smelting process of stove and periodicity, sharp change, when bessemerizing, substantial amounts of high-temperature flue gas flows through waste heat boiler, waste heat
The thermic load of boiler sharply increases；When blowing stops, the thermic load of waste heat boiler strongly reduces, this severe service condition
Necessarily the service life of waste heat boiler is had an impact.At present, the service life of Converter Residual Heat Boiler is very short, epimere cooling stack
Average life span be 6 years or so, life-span of hypomere cooling stack is 2~3 years, and movable gas hood due to service condition more
Badly, the life-span of movable gas hood only has 1 year or so.Due to movable gas hood be mainly used in coordinating the more preferable supplementary set of fixed petticoat pipe,
Caused high-temperature flue gas in converter steelmaking process is dredged, while prevents extraneous air intrusion effect coal-gas recovering quality and prevents
Flue gas escapes deterioration workshop condition.Therefore, the design of Converter Residual Heat Boiler particularly movable gas hood is most important, and it is directly affected
The normal production of converter.
The structure of movable gas hood is used at present：Including water inlet header and water outlet header, header of intaking and water outlet collection
Heat sink is provided between case, heat sink is horizontal positioned by several and caliber is longitudinally superimposed for 51mm annular heat-absorbing pipe
Form, and heat sink is in integrally truncated cone-shaped, the inside of every annular heat-absorbing pipe in heat sink respectively by two block weldings in
Dividing plate on annular heat-absorbing pipe inner tubal wall is separated into two sections of relatively independent heat absorption pipeline sections, the every annular heat-absorbing in heat sink
It is respectively arranged with water inlet and delivery port on every section of pipe heat absorption pipeline section, every section of heat absorption of every annular heat-absorbing pipe in heat sink
The water inlet of pipeline section is connected by the first branch pipe with water inlet header respectively, every section of suction of every annular heat-absorbing pipe in heat sink
The delivery port of heat pipe section is connected by the second branch pipe with water outlet header respectively.During work, the water for header of intaking is through each first
Guan Houcong respectively absorb heat pipeline section water inlet enter it is each heat absorption pipeline section, again from it is each heat absorption pipeline section delivery port enter through each second branch pipe
Water outlet header.Above-mentioned movable gas hood has the following disadvantages：Water inlet and the water outlet in each heat absorption pipeline section are flowed primarily through due to water
Region between mouthful, cause to go out in the region in heat absorption pipeline section between water inlet dividing plate corresponding with homonymy and heat absorption pipeline section
The exhaust of the sloughs such as the region between the dividing plate corresponding with homonymy of the mouth of a river is not smooth, and remaining gas is easily in slough collection in water
Knot, in the presence of fluctuating hydraulic pressure in use, these gases for concentrating at heat absorption pipeline section slough can be compressed continuously, resilience,
So as to which the heat absorption tube wall to slough and dividing plate produce continuous continual impact, cause the weldering between annular heat-absorbing pipe and dividing plate
Drawing crack is sewed, so as to cause annular heat-absorbing tube leakage, causes movable gas hood service life short；And once find annular heat-absorbing pipe
Leak, steel mill blowing out can be forced to rebuild, the service life of movable gas hood only has or so half a year at present, and average monthly necessary
Blowing out is wanted to carry out soldering to movable gas hood twice, each soldering is time-consuming 6 hours or so, leverages manufacturing schedule, while
Increase the danger of service work.
The content of the invention
