Description
Technical field
The utility model relates to the slag process field, relates in particular to a kind of drum process slag treatment system.
Background technology
Drum process slag treatment technology is: pour into the high-temperature liquid state slag on the shunting disk of cylinder internal rotation by funnel, after carrying out drainage, dispersion, enter the water that is cooled squirt in the cooled steel ball separate, cooling curing, fragmentation, the character intrinsic according to material again, the tiny slag in broken back will be rolled into the bottom, drain to betransported out on the drag conveyer of cylinder bottom and, finish the entire treatment process.Drum process slag treatment facility is by its function branch: comprise cylinder body, dreg removing system, steam-dump system, give water sprinkler system, Controlling System and utility appliance.The cylinder body is the core component that the drum process slag is handled, and slag carries out subregion classification chilling, curing, three technological processs of fragmentation by multimedium in the cylinder body, and realization fragmentation and slag separate synchronously with steel to be finished.
The drum process slag is handled and has been realized slag process for producing safe, continuous high-efficientization, environmental protection resource utilization.It possesses following characteristics: clean environment firendly: the slag treating processes is carried out in airtight container, has realized the production that cleans of residues processing technique, and wastewater zero discharge, steam contain heavy amount and be lower than national standard.The slag steel separates: the drum process residues processing technique has carried out good separating to slag with steel, metal not only can online magnetic separation, saved the up to ten million investment of subsequent process, and the taste of slag steel and the rate of recovery are all far above traditional technology, calcium oxide in the slag is effectively cleared up, form stable calcium hydroxide, for high added value and the degree of depth recycling of slag have been opened up bright prospects.
One of important device that spray cooling system is handled as the drum process slag, its spray cooling performance has a direct impact shrend and the fragmentation of water consumption and slag, directly has influence on slag treatment effect and economic benefit.Its cooling principle is with spray water cooled interior medium---steel ball, steel ball by cooling cools off red-hot slag again, water coolant can not be sprayed directly on on the red-hot slag, avoid red-hot slag parcel water and blast, do not blast in order to reach good cooling performance, therefore position and the angle to shower nozzle has very high requirement.
Existing slag is handled the cooling spray position as shown in Figure 1, because the rotation of cylinder body 2, steel ball 8 can form a face that tilts under gravity and the effect of roll friction power in cylinder, inclined degree is relevant with drum rotation speed, drum rotation speed is more fast, and inclined degree is more big.The position that slag 4 drops on the steel ball face is the slag input point, and slag input point is under slag inlet 1, and cooling spray 3 extend into the cylinder body 2 from slag inlet 1, and the water spraying direction of cooling spray 3 is the below of slag input point 4, and the area of former spray face 5 is very little; Because the position of water spray is lower, cooling area is less, and its cooling performance is relatively poor under the prerequisite of same confluent, so can need a large amount of water coolants, the cooling water inflow conference causes the interior water level rising of cylinder to flood the steel ball face, just may blast if at this moment pour red slag again into.So for safety and keep production, water level rises in the cylinder in order to avoid cause, and can only adopt the reduction confluent in the prior art, little confluent is not enough to steel ball and bits cooling, easily produces red slag; Red slag can bring hidden danger to chain mat machine and cylinder itself, and after steel ball was continuously rubescent, warm sludge easily passed red ball and enters the cylindrical shell outer tank, also can blast.The method that must adopt the gap to produce in actual production is so namely produced the cooling of must stopping after for some time continuously, could continue production, has had a strong impact on the performance of cylinder production capacity owing to the restriction of cooling performance.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of drum process slag and handles spray cooling system, cooling system has moved and has raised the position of cooling spray, the area of spray cooling steel ball is doubled approximately, has reduced cooling water consumption, has improved the operating efficiency of cylinder.
The utility model is achieved in that a kind of drum process slag processing spray cooling system, comprise cylinder body and cooling spray, the center of described cylinder body is provided with slag inlet, radially be provided with a baffle plate in the cylinder body, described cooling spray passes slag inlet and extend in the cylinder body, be provided with a circle grate bar around slag inlet in the cylinder body, the grate bar is unsettled to be erected in the cylinder body, grate bar one end is fixed on the inwall of cylinder body, the grate bar the other end is fixedly mounted on the baffle plate, be placed with a pile steel ball on the described grate bar, horizontal direction with cylinder body radial section is the x axle, and vertical direction is the y axle, and the axle center is initial point, the sense of rotation of cylinder body is positive dirction, and described cooling spray is arranged on the intrinsic fourth quadrant of cylinder position.
The water spraying direction of described cooling spray and horizontal direction angle are 25 ° ~ 35 °.
Described cooling spray be arranged in 3/4 place that is higher than cylinder body internal diameter in the cylinder body.
The spray field angle of described cooling spray is 20 ° ~ 25 °.
The utility model drum process slag is handled the position that spray cooling system had moved and raised cooling spray, cooling surface is become the top of slag from the below of slag, the area of spray cooling steel ball is doubled approximately, when reaching identical cooling performance, cooling water inflow is reduced to 60 ~ 80 tphs after the improvement by 120 original tphs, reduced cooling water consumption, can also make the interior water level of cylinder can not rise and flood the steel ball face, make the slag treatment facility to produce continuously, need not the cooling that stops production, improve the cylinder operating efficiency, improved economic benefit.
