Description
Technical field
It the utility model is related 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, 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, and 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, service life of hypomere cooling stack is 2~3 years, and movable gas hood due to service condition more
Badly, the service life of movable gas hood only has 1 year or so.Due to movable gas hood be mainly used for coordinating the more preferable supplementary set of fixed petticoat pipe,
The high-temperature flue gas produced 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, 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, the annular heat-absorbing pipe that heat sink is horizontal positioned by several and caliber is 51mm is longitudinally superimposed
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
Partition 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 water outlet 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 water outlet 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 water outlet 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, causes to go out in the region in heat absorption pipeline section between water inlet partition plate corresponding with homonymy and heat absorption pipeline section
The exhaust of the sloughs such as the region between the partition plate corresponding with homonymy of the mouth of a river is not smooth, and remaining gas is easily in slough collection in water
Knot, under the action of fluctuating hydraulic pressure in use, these gases for concentrating at heat absorption pipeline section slough can be compressed continuously, spring back,
So as to which the heat absorption tube wall to slough and partition plate produce continuous continual impact, cause the weldering between annular heat-absorbing pipe and partition 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, can force steel mill blowing out to be rebuild, and the service life of movable gas hood only has or so half a year at present, and average monthly necessary
Want blowing out twice to movable gas hood carry out soldering, each soldering take 6 it is small when or so, leverage manufacturing schedule, while
Increase the danger of service work.
