Description
Technical field
The plugging device that the utility model relates to stitch between a kind of electric furnace water-cooling flue and water cooling sliding sleeve, belongs to metallurgical environmental protection skill
Art field.
Background technique
As shown in Figure 1, electric furnace 1 can generate a large amount of 1000~1400 DEG C of high-temperature dust-containing flue gas in steelmaking process, it is
Guarantee that the working condition environment inside electric furnace 1 is not destroyed by external interference, high-temperature dust-containing flue gas can only first pass through electric furnace
Exhaust smoke hole on lid 2 is diffused to outside furnace naturally, is then again absorbed it together with air outside the furnace of part by water-cooled flue 3, conveying
To combustion settling chamber 4, the sedimentation of flue gas large particle and the consumption burning of toxic gas CO are carried out.
As shown in Fig. 2, the production in view of electric furnace needs, furnace lid 2 needs the operation for being lifted or being rotated often
Movement, therefore, must at least keep the bell of 50cm spacing between the air inlet of water-cooled flue 3 and the exhaust smoke hole flange 5 of electric furnace
Activity space.When being collected to flue gas, water cooling sliding sleeve 6 under the driving of water cooling sliding sleeve driver 7, from floss hole start to
5 direction of the exhaust smoke hole flange stretching, extension of furnace lid is close, but finally still needs to keep certain minimum spacing, in order to prevent
Powerful flue gas draft destroys the working condition environment inside electric furnace.
As shown in figure 3, there are the gap of 2cm or so, this gaps between water cooling sliding sleeve 3 and water-cooled flue 6 in the prior art
Effect be that water-cooled flue is irregular or surface rough because of its size in order to prevent, caused by the sliding of water cooling sliding sleeve it is dynamic
That makees is obstructed.Although the presence in this gap in the potential problem for objectively solving water cooling sliding sleeve sliding action and being obstructed, it
Also bring along new trouble and problem:
(1) by this gap, the cold wind outside a large amount of electric furnace is mixed among water-cooled flue；
(2) presence in this gap weakens water-cooled flue to the capacity gauge of electric furnace flue gas, so that electric furnace high-temperature dust constaining
The rate of recovery of gas is greatly reduced；
(3) reduction of electric furnace flue gas dust removing effects is eventually led to, flue gas waste heat recovery heat is reduced, and blower power consumption increases.
In view of this, how to realize the closure to stitching between water cooling sliding sleeve and water-cooled flue, and it is preferably minimized its air leak rate of air curtain,
Become the root problem of the utility model research.
