Description
Technical field
The utility model belongs to State of Blast Furnace forehearth technical field, is related to a kind of small flushing cinder mesh region water circulation dress of improvement
It sets.
Background technique
Currently, most of clinker caused by blast furnace process uses flush slag operation, it will by high-pressure high-flow washing slag water
Clinker is rushed with water slag groove to slag bath.But domestic small part blast furnace is due to cast house area and the limitation of other conditions, Wu Fa
The water slag groove of cast house setting long range.Therefore, blast furnace is to meet specific iron mouth slag treatment process requirement, introduces small flushing cinder system
System.Small flushing cinder system primary structure includes: the cone section of the high 4m in lower part, is that a grid platform is arranged at 3m in vertebral height,
For filtering the slagging and the sundries that are greater than 50mm.It is the cylindrical body of high 4m above centrum, cylinder diameter 3m, on the cylinder
Side's setting tightening mouth, for tightening mouth when being contracted to 800mm, drawing a height is 16m exhaust pipe, for discharge generated in flushing cinder tank it is big
Measure steam.Cinder notch once is set in flushing cinder tank, parallel with table slag runner end, the clinker for drawing blast furnace process generation flows into punching
Slag ladle.Under face below cinder notch at 200mm, then setting flushing cinder water inlet is flowed for introducing washing slag water water quenching high temperature furnace slag
Into flushing cinder tank.It is to open a maintenance door at 7m in flushing cinder tank height, is used for clearing up sundries and current check in tank, small flushing cinder system
When system operation, maintenance door is in close state.Slurry pipe is connected in flushing cinder tank lower part centrum end, for slag in timely drain tank
Slurry.
Usual situation, when small flushing cinder system is run, tank interior needs to keep 3.7-4m high water level, primarily to protection
Tank structure is not damaged by high temperature furnace slag.Grid is in slurry area inside tank, flows into flushing cinder since washing slag water belongs to high pressure conditions
Tank, when in flow into tank, parabolically shape, washing slag water drop point can offset out grid central point, necessarily cause circulation effect inside tank
Fruit is uneven, and mesh region has circulation blind area, and slagging movement speed is deteriorated in blind area, and grid is caused easily to accumulate grain slag.With
The bulk deposition of grid blind area grain slag, necessarily causes grid to block.After grid blocking, tap cinder iron job interruption, blast furnace must
So implement promptly to block up, seriously affects blast furnace safety production.
Utility model content
In order to overcome the disadvantages mentioned above of the prior art, the utility model provides a kind of small flushing cinder mesh region water circulation of improvement
Device, it can draw washing slag water to grid blind area, improve mesh region water circulating effect, eliminating grid, there are heaps caused by blind area
Ponding slag phenomenon.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of small flushing cinder mesh region water of improvement follows
Loop device, including small flushing cinder tank, small flushing cinder tank rear side is connected with cinder-flushing water pipe, close to cinder-flushing water pipe position in small flushing cinder tank
On circulating water pipe is installed, the lower end integration of small flushing cinder tank is connected with lower part centrum, in small flushing cinder tank and lower part centrum interval
Grid is installed, lower part centrum bottom is then connected with slurry pipe at position.
The circulating water pipe diameter is 150mm, and arc-shaped, water outlet is parallel with grid, and water outlet length is 100mm；
Water intake end is connected with cinder-flushing water pipe water outlet, and water intake end length is 200mm；When the operation of small flushing cinder system, washing slag water is followed
Ring water pipe shunts mesh region immediately below fraction washing slag water to washing slag water, realizes that washing slag water is former in mesh region quadratic distribution
Reason solves the problems, such as that grid blind area causes grid to block because of accumulation grain slag to eliminate the presence of mesh region water circulation blind area.
The small flushing cinder tank top is provided with chimney, is provided with maintenance door on side wall.
The beneficial effects of the utility model are: realizing washing slag water in mesh region quadratic distribution principle, to eliminate grid
Regional water recycles the presence of blind area, solves the problems, such as that grid blind area causes grid to block because of accumulation grain slag.Circulating water pipe will not shadow
Ring tank interior flushing cinder water flow, the water level to liquidate in slag ladle；The washing slag water introduced using circulating water pipe, in grid platform blind area
Convection current is formed, tubular body grain slag is rushed to lower part centrum, avoids grid blind area accumulation grain slag phenomenon.Reduce the small punching of blast furnace
Slag system fault in production rate improves the small flushing cinder system security reliability of blast furnace.
Detailed description of the invention

Fig. 2 is the utility model top view.
1. chimney in the figure；2. maintenance door；3. grid；4. lower part centrum；5. slurry pipe, 6. circulating water pipes；7. slag runner；
8. cinder-flushing water pipe.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
Referring to Fig. 1 and Fig. 2, a kind of to improve small flushing cinder mesh region water circle device, including small flushing cinder tank, after small flushing cinder tank
Side is connected with cinder-flushing water pipe, is equipped with circulating water pipe on the cinder-flushing water pipe position in small flushing cinder tank, under small flushing cinder tank
End integration is connected with lower part centrum 4, is equipped with grid 3, lower part centrum 4 at small flushing cinder tank and 4 interval location of lower part centrum
Bottom is then connected with slurry pipe 5.
The diameter of the circulating water pipe is 150mm.Circulating water pipe is arc.
The circulating water pipe water outlet is parallel with grid 3, and water outlet length is 100mm；Water intake end and cinder-flushing water pipe 8 are discharged
Mouth is connected, and water intake end length is 200mm.When the operation of small flushing cinder system, washing slag water shunts fraction flushing cinder along circulating water pipe
3 region of grid immediately below water to washing slag water.
The small flushing cinder tank top is provided with chimney 1, maintenance door 2 is provided on side wall.
The utility model realizes washing slag water in 3 region quadratic distribution principle of grid, so that it is blind to eliminate 3 regional water of grid circulation
The presence in area solves the problems, such as that 3 blind area of grid causes grid 3 to block because of accumulation grain slag.Circulating water pipe will not influence tank interior
Flushing cinder water flow, the water level to liquidate in slag ladle；The washing slag water introduced using circulating water pipe forms convection current in 3 platform blind area of grid,
Tubular body grain slag is rushed to lower part centrum 4,3 blind area of grid accumulation grain slag phenomenon is avoided.Reduce the small flushing cinder system of blast furnace
Fault in production rate improves the small flushing cinder system security reliability of blast furnace.
