Case: it is the cooling tower of 4000m3/h that certain circulation, which has specified water process amount, and cooling tower water inlet height is 10
Rice, cooling tower air inlet top is 5 meters high, and backwater pressure head is 17 meters before cooling tower valve, and blower fan of cooling tower necessary electromotor power is
185kW, air quantity 315 × 104m3/ h, density of moist air 1.1358kg/m3.Blower fan of cooling tower actual motion power is 149kW,
Cooling tower actual motion flow is 3800m3/h.System water supplement amount is 80m3/h。
System power surplus is calculated by formula P=ρ × g × Q × H ÷ 3600, is calculated by 11 meters of pressure heads more than needed
When, gross energy of having more than needed is 113.9kW, and power needed for power surplus is much smaller than blower fan of cooling tower can not be driven using pure water turbine
It is dynamic, water-electricity combination drive need to be used, but cooling tower floats that water is excessively high can not still to be solved.
Reduced while solving the problems, such as cooling tower invisible waste electricity using the atomizing cooling tower device of the utility model cold
But tower floats water.It is given and is supplemented using Intelligent pressure unit while power surplus deficiency, obtain system power surplus sufficiently
Utilization.Implementation process is as follows:
Atomizing cooling tower device is arranged in cooling tower using multiple atomizing module combinations.Single atomizing module can root
It is combined design according to different flows, the single atomizing module of this project is according to 106m3/ h design.
Atomizing cooling tower device can pass through propulsive thrust calculation formula F=ρ Qv (F: propulsive thrust, unit N under design discharge；
ρ: the density of water, units/kg/m3；Q: flow, unit m3/s；V: flow velocity, unit m/s) thrust under metered flow is calculated,
Pass through torque arithmetic formula: T=FL (T: torque, unit Nm again；F: propulsive thrust, unit N；L: moment length, unit m) and revolving speed
Calculation formula: n=v ÷ C × 60s (n: revolving speed, unit r/min；V: flow velocity, unit m/s；C: circumference, unit m) calculate volume
Torque and revolving speed under constant flow.Then pass through formula P=T × n ÷ 9550 (P: power, unit kW；T: torque, unit Nm；
N: revolving speed, unit r/min；9550: constant) spray module work done rate under metered flow and pressure head is calculated.Finally from public affairs
Formula P=ρ gQH (P: power, unit kW；ρ: the density of water, units/kg/m3；G: acceleration of gravity, unit m/s2；Q: flow, unit
m3/s；H: pressure head or lift, unit m) inverse go out the atomizing module pressure head required when reaching metered flow.Such as system pressure more than needed
Head is lower than the value, then starting is equipped with the supercharging device 16 of frequency converter；If individual atomizing modules break down or block, then can pass through
The water inlet pressure head of single atomizing module is improved to reach cooling effect.
It is calculated by above formula it is found that unit atomizing module presses 106m3When/h is designed, pressure head needed for system is 12.32
Rice.As system pressure head of having more than needed need to increase lower than the value or flow system flow or when atomizing module blocks by being equipped with the pressurization of frequency converter
16 Automatic-boosting of device when having more than needed pressure head higher than the value such as system, then enters atomizing module by bypass water pipe 14, is equipped with and becomes
Branch water inlet pipe 19 where the supercharging device 16 of frequency device is automatically closed.
This project hydraulic turbine is had more than needed -6 meters of pressure head=17 meter=11 meter
17 meters: for backwater pressure head；
6 meters: atomizing module mounting height is installed on air inlet 6 and pushes up 1 meter of left-right position；
It can be seen from the above calculation that system is had more than needed, pressure head is insufficient, need to supply 12.32 meters using using Intelligent pressure unit, and
The pressure head and flowmeter mended on demand calculate 16 power consumption of supercharging device that frequency converter is housed.
(3) to make intelligent atomizing cooling tower play preferable cooling effect, hydraulic turbine smart spraying cooling tower gas-water ratio is pressed
1.3 designs, and by the air quantity and wind pressure of gas-water ratio design the driven blower of the hydraulic turbine, according to actual air quantity, wind pressure and revolving speed
Design alternative blower.It can specifically be calculate by the following formula:
Gas-water ratio=into tower air quality flow Q gas m ÷ into the mass flow Q water of tower water
Into tower air mass flow Q gas=into tower air quality flow Q gas m ÷ density of moist air ρ mm
Q gas m: into tower air quality flow (kg/s)
Q water: into the mass flow (kg/s) of tower water
Q gas: into tower air mass flow, i.e. air quantity (m3/h)
ρ m: density of moist air (kg/m3)
Because blower is directly driven by the propulsive thrust of spraying device, the propulsive thrust of spraying device is the input work of blower
Rate, so fan pressure can be obtained by power of fan formula inverse, it may be assumed that
Fan pressure=hydraulic turbine acting × 3600 × 1000 × η blower ÷ air quantity Q gas
Wind pressure unit: Pa
The hydraulic turbine does the unit of work: kW
Air quantity Q gas unit: m3/h
