Topic remains one of the main problem for influencing unit safety economical operation.Summer high temperature stage Direct Air-cooled Unit back pressure can
Reach 45-50 kPa, seriously affects the safe and economic operation of unit.In this way in order to guarantee unit safety operation, under high temperature,
Unit will have to load limit operation to some extent.Due to when operation condition in summer, which is in power grid, crosses summer heavy-duty service
Phase, and be also exactly the environment temperature high period from peak load in terms of the peak regulation angle of unit.Therefore unit will necessarily go out in summer
Existing long period big load high back pressure load limit operation operating condition is returned once there is such as strong wind weather and hot wind in this case
The rough sledding such as stream, it is easy to cause the appearance of back-pressure protection movement unit tripping problem.In this way, not only giving unit safety operation
Serious threat is brought, while also directly influencing the safe and economic operation of power grid.
In view of this, the utility model proposes a kind of air cooling tubes condenser spray humidification cooling system of combination deflector,
The system is by the way that atomizer to be arranged in right above air-cooled unit internal diversion plate outlet, to make more preferably to riddle by spraying whole
Inside a air-cooled unit, the temperature of the air into inside air-cooled unit is reduced, air-cooled unit internal heat efficiency is improved, dropped
Low unit back pressuce, to guarantee Direct Air-cooled Unit is safe and stable, economic operation.
Summary of the invention
In order to solve the above problem, the utility model uses following technical scheme:
A kind of air cooling tubes condenser spray humidification cooling system of combination deflector, the system include: condensate tank 1, multistage
Centrifugal pump 3, the first regulating valve 2, the second regulating valve 4, spraying main pipeline 5, spraying branch pipe(tube) 9, deflector 6, atomizer 7, sky
Cold unit 8；It is characterized by: the condensate tank 1, the first regulating valve 2, centrifugal multistage pump multiple centrifugal pump 3, the second regulating valve 4, spraying master
Pipeline 5 is sequentially connected；Spraying branch pipe(tube) 9 is connected with spraying main pipeline 5；Atomizer 7 is connected with spraying branch pipe(tube) 9；It leads
Flowing plate 6 is connected with air-cooled 8 bottom of unit.
The centrifugal multistage pump multiple centrifugal pump 3 passes through second after extracting demineralized water in condensate tank 1 after centrifugal multistage pump multiple centrifugal pump pressurizes
The control of regulating valve 4 after flowing through spraying main pipeline 5, is sent to each atomizer 7 being arranged on spraying branch pipe(tube) 9, atomizer
7 will spray into inside air-cooled unit 8 after desalination water atomization；Air is led by deflector 6 back into inside air-cooled unit 8, is encountered
Air themperature reduces after spraying, leaves after completing heat exchange in air-cooled unit 8, into atmosphere.
8 bottom of air-cooled unit is disposed with deflector 6.The spraying branch pipe(tube) 9 and atomizer 7 is arranged in and leads
The surface of 6 air outlet slit of flowing plate.
The utility model has the following advantages that and the utility model has the advantages that when summer environment temperature is higher, sprays compared to not containing
The air-cooled unit of mist humidification system, the system, will be after the desalination water atomizations extracted in condensate tank by utilizing atomizer
It sprays into inside air-cooled unit, the air themperature being lowered into inside air-cooled unit, improves heat exchange efficiency, reduce unit back pressuce, and
Atomizer is arranged in right above deflector outlet, more preferably makes to riddle by spraying inside entire air-cooled unit, it is therefore prevented that water resource
Waste, ensure that the operation that Direct Air-cooled Unit is safe and stable, economic.
