Specific embodiment
Below with reference to Fig. 1 and Fig. 2, the present invention will be further described:
As shown in Figure 1, a kind of cooling water recirculation system, including cooling tower 1, water circulating pump 2, heat exchanger 3, the other filter dress of electrolysis
4 and impulse turbine 5 are set, energy is obtained in water circulating pump 2 by the cooling water after cooling tower 1 and air heat-exchange, it is preceding
It exchanges heat toward heat exchanger 3 and steam turbine steam exhaust to condense steam exhaust；Before this, water circulating pump 2 distributes a part of flow and passes through pressure
Water pipe 19 is for driving the hydraulic turbine 5 to do work.
Return flow line is equipped between cooling tower 1 and heat exchanger 3.Water circulating pump 2 distributes a part of flow and is also directly entered
In the other filter device 4 of electrolysis, and flow back into cooling tower 1.The water being discharged from water outlet 15 is back in cooling tower 1.
Filter device 4 is a kind of to be rotated using hydraulic turbine driving scraper to remove scale referring to shown in Fig. 2 by electrolysis in Fig. 1
Electrolysis by filter device, including penstocks 19, the other filter crust of the device 11 of electrolysis, hydraulic turbine shell 13 and pedestal 14, it is described
It is installed above hydraulic turbine shell 13 and filters crust of the device 11 by the electrolysis, be set as the pedestal below the hydraulic turbine shell 13
14, the penstocks 19 are connected with the water inlet pipe of the hydraulic turbine 5, and the water in the penstocks 19 is impacted by nozzle 17 in water
On the bucket 16 of Turbine Runner runner is rotated, shaft upper and lower ends are separately connected scraper 12 and runner, and shaft passes through shaft coupling
Device is connected with scraper 12, and the rotation of driven by rotating wheel scraper 12 simultaneously carries out scale removal to the other filter device cylinder inner wall of electrolysis.
It further include flow control valve 18, the control of flow control valve 18 enters the water flow of the hydraulic turbine 5 and scrapes to adjust
The revolving speed of knife 12.Water in penstocks 19 done manual work by the hydraulic turbine 5 after water via the diversion pipeline in the pedestal 14 from
Water outlet 15 is discharged.
Its working principles are as follows: a part of water flow that the cooling water after water circulating pump distributes, by pressure pipeline
19, water wheels machine nozzle 17 impacts on the bucket 16 of rotary wheel of water turbine, rotates runner hydraulic turbine acting, shaft passes through connection
Axis device is connected with scraper 12, drives scraper rotation to achieve the purpose that ESF cathode scale removal.Water wheels are adjusted in flow control valve 18
The flow of machine, and then the power of the hydraulic turbine can be adjusted, and then adjust 12 revolving speed of scraper according to different operating conditions.Pass through the hydraulic turbine
Recirculated water after workmanship is discharged via the diversion pipeline in pedestal 14 from water outlet 15, flows to cooling water replenishment system, Jin Erliu
Enter the water cooling pond of cooling tower bottom.Part cooling water enters, In by another extraction by the water inlet below ESF ontology
Cell reaction scale removal sterilization occurs in ESF ontology, then is discharged by the water outlet of top, into the water cooling pond below cooling tower.
Scale is periodically scraped by scraper 12 and is fallen in ESF body bottom portion on cylinder inner wall by fouling, then is discharged by slag-drip opening.
A period of time interior about 12h can completely handle a cooling water and possess water.
The hydraulic turbine is done work using the kinetic energy and potential energy of fluid, and the mechanical equipment for being translated into mechanical energy and exporting is divided into
Reaction turbine and impulse turbine.Impulse turbine head utilization scope is big, and efficiency curve is gentle (will not be because of stream
Amount changes but efficiency declines to a great extent), convenient for significantly flowed fluctuation adjusting；Digging is deep smaller, without installing biggish tail
Water pipe saves space occupied；Impulse turbine flow passage components structure is simple, maintains easily and overhauls, and to water quality requirement
It is not high.Therefore reaction turbine is compared, impulse turbine is more suitable for the mating driving device as ESF scraper.Impact
The working principle of the formula hydraulic turbine is as follows: having the water flow of certain head by diversion Tube Drain, cooperates by nozzle needle and adjust stream
After amount, bucket on directive runner, the moment of momentum changes when water flow passes through bucket, so that kinetic energy is transmitted water supply by runner
Turbine main shaft, then exported by shaft coupling.General cooling water circulating pump in order to ensure the safe and stable operation of cooling water system,
It will reserve certain lift allowance (energy allowance), this part water energy more than needed generally consume former for controlling flow
It anticipates at the valve to build the pressure, causes energy dissipation in vain.Therefore cooperation hydraulic turbine driving scraper rotation can make full use of circulation cold
But the remaining water energy in water lines reduces energy dissipation.
Above in conjunction with attached drawing, an exemplary description of the invention, it is clear that realization of the invention is not by aforesaid way
Limitation, as long as use the inventive concept and technical scheme of the present invention carry out various improvement, or it is not improved will be of the invention
Conception and technical scheme directly apply to other occasions, be within the scope of the invention.
