Description
Technical field
The utility model relates to the filtration system technical fields more particularly to one that dedusting steel-smelting converter turbid circulating water is recycled
Kind steelmaking converter turbid circulating water secondary treatment system.
Background technique
Steelmaking converter needs to use dust pelletizing system in the process of work, and dust pelletizing system mostly uses the side of wet dedusting
Formula sprays water mist to high-temperature flue gas by spray column, plays the role of cooling and dedusting to flue gas, in order to save water money
The recycling of resource is realized in source, and dust pelletizing system is equipped with a set of water treatment system, and the water in water treatment system is just referred to as
Turbid circulating water.
A kind of " turbid ring of converter dust-removing is disclosed in the utility model patent specification of Publication No. " CN204107177U "
The filtration system that water is recycled " in the technical scheme carries out turbid circulating water by laminated filter and inclined-plate clarifying basin
Circulating filtration, structure is relatively easy, and efficiency of dust collection is low, needs frequently to be cleared up, influences working efficiency.
System structure of the another kind for handling converter turbid circulating water is as shown in Figure 1 comprising passes sequentially through piping connection
Converter dedusting line 1-1, inclined-plate clarifying basin 1-2, mud pit 1-3, plate and frame filter press 1-4 and pond 1-5, the work of the system
Principle are as follows: the water in dust removal in converter dedusting line 1-1 is flowed into inclined-plate clarifying basin, after the filtering of inclined-plate clarifying basin,
More clean overflow water flows directly into the 1-5 of pond, and another part muddy water sinks to the bottom of inclined-plate clarifying basin, pumps by taking out you
It is pumped into mud pit, then into plate and frame filter press 1-4, by the processing of plate and frame filter press 1-4, filtered liquid
Also it is flowed into the 1-5 of pond, the water in the 1-5 of pond is returned to by the water pump in pump house 1-6 to converter dedusting line 1-1
In, it realizing and is recycled, remaining sludge is transported by other after filtering in above-mentioned plate and frame filter press 1-4, it focuses on,
In the technical solution, due to the structure and working principle of plate and frame filter press 1-4 itself, for muddy water clean-up effect not
Be it is very high, the water sent back in the 1-5 of water sedimentation pond contains a small amount of mud, fouling blockage water return pipeline and can subtract after long-time service
Few yield increases the frequency of cleaning and maintenance, and then influences manufacturing schedule.
In conclusion needing to develop, a kind of structure is more perfect, the better steelmaking converter turbid circulating water for the treatment of effect is secondary
Processing system.

As shown in Fig. 2, steelmaking converter turbid circulating water secondary treatment system described in the present embodiment, including pass sequentially through pipeline company
The hot-tub 1 that connects, water cooling pond 2, pump house 3, converter dedusting line 4, coarse separator 5, inclined-plate clarifying basin 6, slurry conveying machine 7,
Mud pit 8 and plate and frame filter press 9；
The overflowing water port of inclined-plate clarifying basin 6 is connect by overflow passage 10 with the water inlet of hot-tub 1；
Blank-plate valve 11 is provided between plate and frame filter press 9 and hot-tub 1；
The water outlet of plate and frame filter press 9 is connect by water return pipeline 12 with the water inlet of inclined-plate clarifying basin 6, water return pipeline 12
On be provided with return water sedimentation basin 13.
Self priming pump 14 is provided on water return pipeline 12.
Blank-plate valve 11 is provided between plate and frame filter press 9 and return water sedimentation basin 13.
Water in hot-tub 1 is squeezed into water cooling pond 2 by circulating pump to be cooled down, and the water pump in pump house 3 is then passed through
It squeezes into converter dedusting line 4, in the present embodiment, converter dedusting line 4 is converter spray column, carries out sprinkling dedusting, is spraying
During spilling, water plays the role of depositing dust and cooling, so the water after dedusting is the turbid circulating water with certain temperature, in this reality
It applies in example, the turbid circulating water after dedusting is fallen in collecting tank, is entered in coarse separator by overhead chute (diversion trench), is carried out
Pretreatment, the biggish impurity of particle are separated, and are transported to other places, the processing concentrated contains short grained turbid ring
Water is entered under the action of circulating pump in inclined-plate clarifying basin 6, carries out sloping plate deposition filtering, the upper layer of inclined-plate clarifying basin 6 is more
Clean water is discharged by overflowing water port, is pumped into hot-tub 1 through overflow passage 10, inclined-plate clarifying basin 6 bottom containing mud
Water is delivered in mud pit 8 by slurry conveying machine 7, after running up to a certain amount in mud pit 8, is pumped into plate compression by Pulp pump
It is handled in machine 9, the blank-plate valve 11 between hot-tub 1 and plate and frame filter press 9 is closed, it is filtered through plate and frame filter press 9
More clean water enters in return water sedimentation basin 13, carries out secondary precipitation in return water sedimentation basin 13, after precipitating, regularly clearly
The deposition of 13 bottom of return water sedimentation basin is managed, supernatant liquor is pumped into inclined-plate clarifying basin by self priming pump 14 again in return water sedimentation basin 13
In 6, inclined plate filtering is carried out again, then in overflow to hot-tub, in this way by increasing return water sedimentation basin 13, is followed by multiple
Ring filtering, send the water in the original backheat pond 1 of plate and frame filter press 9 to return water sedimentation basin 13, then by back pool sedimentation basin 13 2 times
Precipitating, is sent water to inclined-plate clarifying basin 6 by self priming pump 14 and precipitated again, and the water quality of the water of inflow hot-tub is by greatly in this way
It improves, solves the problems, such as line clogging, colleague also increases yield.
If the turbidity of turbid circulating water is lower in other words in order to improve efficiency of dust collection, plate and frame filter press 9 and return water can be closed
Blank-plate valve 11 between sedimentation basin 13 opens the blank-plate valve 11 between hot-tub 1 and plate and frame filter press 9, saves filtering in this way
Step can accelerate the circulation rate of the entire circulatory system.
In conclusion the utility model can carry out the selection of mode, using flexible according to practical situation.
