Abstract
The invention provides a technology for charging overbottom pressure of continuously-cast turbid circulating water to a tower. A vortex flow pond, a high-efficiency muddy water purifier and a continuously-cast turbid circulating cooling tower are arranged in a related region, wherein secondary cooling water and device open-circuit cooling water of a continuous casting machine can be respectively collected by the vortex flow pond, and turbid circulating water can be transported to the high-efficiency muddy water purifier to be purified through a pipeline by a pump set of a vortex flow well. Particularly, the high-efficiency muddy water purifier is a sealed container and can generate the pressure. After the technology for charging the overbottom pressure of teh continuously-cast turbid circulating water to the tower, provided by the invention is applied, the turbid circulating water is pumped to the high-efficiency muddy water purifier due to a pump of the vortex flow well by turning off a valve of a hot water charging pond on a turbid circulating water self-flow pipeline and turning on a bypass valve, and the turbid circulating water is transported to the cooling tower by the generated overbottom pressure due to the seal effect of the high-efficiency muddy water purifier, so that the overbottom pressure generated by sealing the high-efficiency muddy water purifier can be effectively used, the use of the pump set of the cooling tower of the continuously-cast turbid circulating backwater can be reduced, the energy loss of the pump can be avoided, and the aims of energy saving, consumption reducing, cost reducing and cost saving are achieved.
Description
Technical field
The present invention relates to a kind of upper tower apparatus, relate in particular to tower apparatus on a kind of continuous casting turbid circulating water overbottom pressure, belong to steel-making circulating water device technical field.
Background technology
The recycling technological process of steel plant continuous casting turbid circulating water is the secondary cooling water of conticaster, equipment open circuit cooling water, the user uses the not only water temperature rising of rear backwater, but also be subject to iron scale and a small amount of oily pollution, backwater flow to the Whirlwind tank that is located in the workshop through the iron sheet ditch, after removing large particle iron sheet, water outlet is directly rushed iron scale with pump lift portion water, remaining water yield is promoted in the efficient muddy water clarifier through another group pump, after adding coagulant and oil flocculant precipitation, in flowing into the turbid ring hot well of continuous casting, add through pump and to compress into cooling tower, add the force feed user through pump again after the cooling and recycle.Totally 3 of the turbid loopback of continuous casting cooling tower supply-water pump waterborne groups, dual-purpose one is standby, and pump group power consumption every day needs 4320 degree, and water pump group off-energy is extremely many.
Summary of the invention
The object of the invention is to solve above-mentioned technical problem, propose tower process on a kind of continuous casting turbid circulating water overbottom pressure.
Purpose of the present invention, to be achieved by the following technical programs: relating to the zone has Whirlwind tank, efficient muddy water clarifier, the turbid ring cooling tower of continuous casting, the hot and cold pond of the turbid ring of continuous casting, described Whirlwind tank is used for collecting secondary cooling water and the equipment open circuit cooling water of conticaster, described efficient muddy water clarifier is used for purifying turbid circulating water, the turbid circulating water of described turbid ring used for cooling tower behind cooling and purifying, the cold and hot pond of the turbid ring of described continuous casting are used for storing cooled turbid circulating water and store by efficient muddy water clarifier from the turbid ring hot water that flows back to.It is characterized in that: make turbid circulating water can reach recycling.
Further, described efficient muddy water clarifier increases bypass conveyance conduit and bypath valve to the conveyance conduit of the turbid ring hot-tub of continuous casting.
Further, described efficient muddy water clarifier is closed container, can produce pressure.
Further, having after described efficient muddy water clarifier will purify presses turbid ring hot water by the by-passing valve of bypass conveyance conduit and unlatching, is delivered to the turbid ring cooling tower of continuous casting.
Beneficial effect of the present invention is mainly reflected in: use tower process on the continuous casting turbid circulating water overbottom pressure of the present invention, the pressure of utilizing airtight efficient muddy water clarifier to produce is pressed turbid circulating water is delivered to cooling tower, effectively utilized overbottom pressure, the energy that has reduced the pump group of the turbid loopback of continuous casting cooling tower waterborne runs off, and reaches energy-saving and cost-reducing, falls the purpose that this section is propped up.
Description of drawings
Fig. 1 is the structural representation of tower apparatus on the continuous casting turbid circulating water overbottom pressure of the present invention.
The specific embodiment
Below in conjunction with the embodiment accompanying drawing, the specific embodiment of the present invention is described in further detail, so that technical solution of the present invention is easier to understand, grasp.
As shown in Figure 1, tower apparatus on the continuous casting turbid circulating water overbottom pressure, comprise and be provided with Whirlwind tank 1, described Whirlwind tank is collected respectively secondary cooling water 2, the equipment open circuit cooling water 3 of conticaster, described efficient muddy water clarifier 4 connects respectively the turbid ring hot-tub 5 of continuous casting by transmission pipeline 51, the turbid ring hot-tub of continuous casting connects cooling tower 6 by the pipeline that is provided with pump 61, and especially, transmission pipeline is provided with switch valve 511.In addition, described efficient muddy water clarifier 4 directly connects cooling tower 6 by bypass transmission pipeline 52, and especially, transmission pipeline is provided with switch valve 521.
During implementation, the secondary cooling water of conticaster, equipment open circuit cooling water enter Whirlwind tank after entering the slag flushing device flushing cinder, by the pump group turbid circulating water is sent into efficient muddy water purification utensil by conveyance conduit through Whirlwind tank, the switch valve 511 of transmission pipeline cuts out, obturation effect by efficient muddy water clarifier produces pressure, turbid circulating water after purifying is entered cooling tower 6 by bypass transmission pipeline 52, so cycling, can reduce the pump group energy loss of the turbid loopback of continuous casting cooling tower waterborne, thus play energy-saving and cost-reducing, the effect that this section is propped up falls.
Can find out by above-mentioned character express, after tower apparatus drops into and implements on the continuous casting turbid circulating water overbottom pressure of the present invention, its beneficial effect is mainly reflected in: use tower apparatus on the continuous casting turbid circulating water overbottom pressure of the present invention, by increasing bypass transmission pipeline and closing switch valve 511, utilize the obturation effect of efficient muddy water clarifier to produce pressure, turbid circulating water is directly delivered to cooling tower, effectively utilized overbottom pressure, greatly reduce pump energy run off, reach energy-saving and cost-reducing, fall the purpose that this section is propped up.
In addition to the implementation, the present invention can also have other embodiment, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the present invention's scope required for protection.
