Intersection, the spray head on spray equipment 4 are arranged towards sink 5, are formed by spray head towards the vertical spray path of sink 5, just
It falls into sink 5 and recycles in the water sprayed out, circulator is set between sink 5 and spray equipment 4, circulator includes
The underwater in sink 5 is arranged in water circulating pump 61 and circulation pipe 62, water circulating pump 61, and 62 one end of circulation pipe is connected to recirculated water
On pump 61, one end is connected on spray equipment 4, and the water in sink 5 is pumped into spray equipment 4 through circulation pipe 62 by water circulating pump 61
It is interior, it is sprayed out of spray head, the water vertical drop of ejection is fallen into sink 5 through the air heat-exchange in overmulling wind chamber 2, circulated sprinkling.
Water level control system is also set up in sink 5, water level control system includes water level controller 7 and temperature sensor (figure
In be not shown), wherein water level controller 7 be arranged in sink 5, in the present embodiment, water level controller 7 use tongue tube water level
Controller can also use floating ball magnetic switch fluid level controller or electrode mode level controller etc., depending on depending on actual need,
Water level controller 7 controls the unlatching of inlet valve in the sink according to the temperature signal that temperature sensor is fed back, closes or go out
The unlatching of penstock is closed., sink 5 can be intake and be drained to keep certain height of water level according to temperature value.When
The temperature of heat exchange can intake when higher into sink 5 keeps high water level, increases the water of heat exchange, and effectively make up higher temperature
Evaporation to moisture；Water in sink 5 can be discharged when the temperature of heat exchange is lower and be reduced to low water level, a small amount of water
Meet heat transfer requirements, economizes on resources.Temperature sensor is arranged in hull outside, is electrically connected with water level controller 7, temperature controller
Real-time monitoring ambient temperature and feedback temperature value are to water level controller 7, when outdoor temperature is lower be easy to cause water freezing, water level
Controller 7 empties the water in sink 5 according to preset temperature value, such as preset temperature value is 0-3 degrees Celsius；Temperature sensor is also
It can be set in sink 5 with real-time detection water temperature, when water temperature is close to freezing point i.e. 0 degree Celsius, feedback temperature signal to water level
Controller 7 with empty in sink 5 water, prevent from freezing and cause the damage of sink 5 and the pipeline being connected to sink 5.
As shown in Figure 1, also setting up heat exchanger 8 in the mixed wind chamber 2 of 4 lower section of spray equipment, air heat-exchange efficiency, this reality are improved
