Description
Technical field
The invention belongs to reservoir stratified pumping technical field, be specifically related to a kind of combination with reservoir intake tower king-tower and evade the device of algae, Main Function enters in reservoir intake tower king-tower in evading algae.
Background technology
Water is Source of life, and drinking water quality is directly connected to huge numbers of families' health, and the height of drinking water quality has reflected a country economy and social development levels from a side.Provide high mark drinking-water to citizen, to prevent disease, improve people's the general level of the health and quality of life important in inhibiting.Rapid with urban development, water requirement increases, and shortage of water resources problem is day by day serious.In in the past more than 50 year, China has built large quantities of reservoir filling engineerings, and therefore large-scale Hu Ku water source becomes the important drinking water source in city gradually.
By the characteristic of distribution of water temperature, reservoir can be divided into into stratotype and the large class of mixed type two.Become stratotype reservoir to have larger water temperature gradient along depth of water direction, storehouse lower floor waterborne is difficult to mix, and the laminar flow part that inflow outflow causes and other stagnation parts are separated from each other.Bottom water temperature changes very little within 1 year.Because the big-and-middle-sized reservoir depth of water after building dam strengthens, vertical Temperature Distribution is three levels: the higher troposphere that is called of upper strata temperature; The lower stratosphere that is called of lower floor's temperature; Middle changeover portion is called the temperature layer that jumps.Winter, bucket temperature was not high, there is no significant thermocline; Summer, water surface temperature was higher, and thermocline is just more remarkable.Due to density difference to some extent between each layer of reservoir, according to density current theory, in storehouse, current stratification distributes, and along the depth of water, catenary motion is constrained, and horizontal movement is strengthened.At the beginning, the water of all levels all flows to before dam earial drainage.Once if form a kind of stable earial drainage state, will outlet form near elevation vertical strict earial drainage layer, one deck density almost constant water quality just discharged to downstream.Therefore,, if sluiced from different elevations, water quality difference is very large.
Solar radiation spring and summer strengthens, most Hu Ku top layer algal bloom, and top layer algae has been limited the transmission of oxygen; Bottom of the reservior, lake layer dissolved oxygen is throughout the year lower, and deposition substrate is releasing nutrients salt, iron and manganese under LDO impact, is that bottom pollutant levels are higher; In upwards storehouse, lake water quality layering of depth, Hu Ku water quality parameter such as frustule content, organic matter, heavy metal, pH, dissolved oxygen, turbidity on different depth is also obviously different.In summary, due to lake warehouse temperature layering, physics, chemistry and the biology of savings water change, and finally cause the layering of Reservoir Water Quality.
Stratified pumping adopts more in the U.S. and Japan.Great majority are to utilize intake tower, on tower wall, have intake along different height, and utilizing machinery is power starting gate, and this mode can obtain the water that water temperature and water quality meet the demands.But be algae burst season comparatively frequently summer, the fixing intake in summer has comparatively fixing sluicing layer thickness, is difficult to active dodge containing the former water of algae, and a large amount of algae are brought into intake tower, will increase the difficulty of water factory's processing and the expense of water treatment.In this case, water tower reveals limitation to obtaining high-quality original water gauge, has given prominence to the selective deficiency that water tower is fetched water to water quality.This can not tackle the algae that the water level that may change at any time causes and be brought into water tower with regard to showing intake, thereby needs new technology and equipment carry out transformation and optimization again to selective withdrawal tower.
Solar radiation spring and summer strengthens, amount reproduction algae within the scope of domestic most Hu Ku top layer in recent years, and in the certain limit of top layer, algae aquatile content increases.Under present case, in order to take the source water of high-quality, how strengthening the selective of intake tower, how to evade containing the former water of algae, how to control and choose the former water lower containing algae degree, is one of problem of paying close attention to of those skilled in the art.
The data-searching of carrying out according to applicant, does not also find active dodge containing the former water of algae and a kind of bibliographical information of initiatively inducing reservoir intake water intaking boundary to further investigate.
Summary of the invention
During for above-mentioned water intaking, existence can not active dodge containing the defect of algae superficial water, the object of the invention is to, provide a kind of combination with reservoir intake tower king-tower to evade the device of algae, reach the object of evading algae.This device flexible operation, simple in structure, has certain effect evading reservoir surface algae and aquatile, solved comparatively neatly due to summer algae increase the problem of the water quality inferiority that causes fetching water, improved water intaking water quality.
For realizing above-mentioned technical assignment, the present invention takes following technical scheme to be achieved:
A kind of combination with reservoir intake tower king-tower evaded the device of algae, comprise the king-tower with operation room, king-tower is sent the water in king-tower tower body by king-tower pressure round pipe, it is characterized in that, also comprise that one is just being opened wide most secondary tower to a side of reservoir area, secondary tower is sent the water in secondary tower by secondary tower pressure round pipe, in secondary tower, be provided with Stoplog gate, this Stoplog gate is made up of upper Stoplog gate and lower Stoplog gate, the hoist engine that Stoplog gate arranges by secondary tower tower body top opens and closes and lifting, wherein, upper Stoplog gate is fixed on the roof of secondary tower, lower Stoplog gate is fixed on the diapire of secondary tower, space between upper Stoplog gate and lower Stoplog gate is as the active intake of secondary tower, between upper Stoplog gate and hoist engine, be connected by the first wire rope, upper Stoplog gate is connected by the second wire rope between Stoplog gate with lower Stoplog gate.
Of the present invention combination with reservoir intake tower king-tower evaded the device of algae, along with being hung in the lifting of wire rope of upper Stoplog gate, initiatively intake lifting thereupon within the specific limits.With Fluent software, this device is simulated, interpretation of result can obtain: the position of secondary tower active intake can directly affect the water intaking scope of king-tower intake.When secondary tower active intake is positioned on king-tower intake, upper strata algae-containing water body mainly flows out from secondary tower, avoids algae to enter king-tower.Be applicable to top layer algae content excessive, have the degree of depth difference of surface water according to the difference of water level and algae, can, by lifting secondary tower intake, choose the former water of high-quality.
Compared with prior art, there is following technological merit:
1) evade algae stronger
According to at-once monitor data, the position of secondary tower intake is accurately located, and then secondary tower will take out containing the former water of algae, guarantee to enter algae in the former water of king-tower and kept low content state.Reduce water factory and processed algae expense, there is certain economic worth.
2) simple in structure
This apparatus structure is by intake tower and Stoplog gate, and secondary tower internal construction is made up of upper and lower section of Liangmen, has formed movably intake between Stoplog gate.The driving force of mobile intake is from the hoist engine in operation room.
3) simple operation
According to on-the-spot water level and correlation water data, only need to open hoist engine, just can arrive the operation of evading algae.
