Description
Technical field
The utility model belongs to the improvement of the air port Ou Yelu cooling water channel circulating system structure, especially a kind of Ou Yelu wind
The safe circulatory system of mouth cooling water channel open circuit.
Background technique
The cooling water channel of the small set of Ou Yelu oxygen wind gap uses closed circuit circulatory system, and locally there is head tank in water route, convenient for inspection
Leakage.But in actual motion, influenced by return water system hydrostatic head, little Tao front chamber water speed is relatively low, and small set melting loss amount is big, influences
Production efficiency.
Ou Yelu is produced two months, and air port consumes ten, and about 1.8 ten thousand yuan of each tuyere small sleeve price adds up to 180,000 yuan.It presses
According to this consumption trend, annual small set process spare part consumption is up to 1,080,000 yuan or so.
Pass through theoretical calculation analysis: oxygen wind gap front end theoretical temperature combustion T manages=3800 DEG C of radiant heat.Blast-furnace tuyere
Front end theoretical temperature combustion T manages=2300 DEG C；The heat flow density of the small set front end face heat affected zone of Ou Yelu oxygen is the small set of blast furnace
1.8 again.The cooling water inflow at Ou Yelu tuyere small sleeve front end face position is only the 66% of the small set of blast furnace, and water shortage is seriously to restrict
The small set of Ou Ye furnace is 10.9m/s by it is low to calculate the low water speed of comparison Ou Ye Lu little Tao front chamber water using long-lived factor, low
In 13 m/s of lower limit water speed of blast furnace tuyere small sleeve, lower than 14 m/s of A/B/C blast furnace --- 17 m/s water speeds.
Because of the small set return water system back pressure 0.8Mpa of Ou Yelu oxygen wind gap, small set, which occurs leaking not carrying out opening a way being depressured, is arranged
It applies.
Utility model content
The purpose of this utility model is to provide a kind of safe circulatory system of air port Ou Yelu cooling water channel open circuit, structures
Rationally, to the cooling water channel optimization design of tuyere small sleeve, it is relatively low and ensure safe operation to can solve little Tao front chamber water speed
Problem extends the service life of small set, reduces air port loss.
The safe circulatory system purpose of the utility model is realized as follows: a kind of air port Ou Yelu cooling water channel is opened a way,
Including the small jacket water road circulatory system of Ou Yelu oxygen wind gap, water supply is set in the tuyere small sleeve cooling water channel circulatory system
The return water tank of pipe and return pipe, return pipe connection is connected to the import of feed pump by double-drum filter, leaf filter, main
The outlet of water pump is connected to water supplying pipe, sets gradually three bypass pipes on water supplying pipe, the first bypass pipe by fast cut valve,
Circulating pump is connected to safe water tower, and the first outlet pipe of safe water tower is connected to emergency pond, and the outlet pipe in pond of meeting an urgent need passes through
Emergency pump is connected to third bypass pipe, and the second outlet pipe of safe water tower is connected on the pipeline between fast cut valve and circulating pump,
Second bypass pipe is connected by hand-operated valve, check-valves with the second outlet pipe of safe water tower.
The utility model realizes open circuit decompression maintenance measure in a leak state, solution by increasing oxygen wind gap water flow
The problem of Jue little Tao front chamber water speed is relatively low and ensures safe operation, and by the analysis to return water system level stability situation,
Leak condition is analyzed, carries out investigation leak detection further according to the variation tendency of specific region cooler difference in flow.Water pipe design configurations
It is unreasonable to cause the cooling resistance damage of small set excessive, limit cooling water flow.
Water resistance damage is cooled back from the small set of water pump value and reaches 0.9MPa, causes when actual production that water pump high pressure water flow is low to ask
Topic.
Direction and measure can be optimized:
1) only oxygen air port is cooling for critical system cooling water, reaches and improves Ou Yelu oxygen wind gap cooling water flow
Purpose meets the cooling requirement of reinforcing of oxygen wind gap little Tao front chamber；
2) reduce pipeline resistance damage: by the water inlet 1 section of water inlet pipe reaming of variable diameter of small set to φ 95*6mm, two sections are changed to by φ 42*5
φ 95*6mm connection；
3) it solves the problems, such as that the small set of Ou Yelu oxygen wind gap not can be carried out decompression open circuit maintenance measure, critical system is discharged
It is changed to the open circuit return water type of cooling, in pylon 16m or 19m setting recovery tank after there is small set breakage, is maintained convenient for diminishing.
It is as follows to small set water route optimization design according to small jacket water line structure:
Small set water cooling is changed to open a way, and return water tank is arranged, two kinds of liquid of high liquid level and low liquid level are installed on return water tank
Position meter.80 meters of water tank of original absolute altitude is changed to safe water tower water-feeding, water is supplemented into inlet tank using 10m3/h small pump.Water
Case is connected with water inlet manifold.Between completely cut off using pneumatic fast cut valve.When factory shows that crucial water pressure is lower than standard 50%, fastly
Valve opening is cut, to tuyere small sleeve water inlet line moisturizing, prevents scaling loss after small set diminishing.
The utility model is compared with original technology, and small set water is big, and water speed is fast, and water speed has reached 14.7m/s, tuyere small sleeve
Service life greatly extend.
The utility model is structurally reasonable, to the cooling water channel optimization design of tuyere small sleeve, solves little Tao front chamber water speed
The problem of relatively low and guarantee safe operation, the service life of small set is extended, reduces air port loss.
