Case: it is the cooling tower of 3500m3/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 19 meters before cooling tower valve, the matched with blower motor function of cooling tower fan blade
Rate is 160kW, 273 × 104m3/h of air quantity, density of moist air 1.1358kg/m3.Blower fan of cooling tower actual motion power is
140.7kW, cooling tower actual motion flow are 3600m3/h.System water supplement amount is 70m3/h.
System power surplus is calculated by formula P=ρ × g × 3600 × η of Q × H ÷, the power surplus of system is remote
It less than power needed for blower fan of cooling tower, can not be driven using pure water turbine, water-electricity combination drive need to be used, but cooling tower floats
Water is excessively high can not still to be solved.
Intelligent atomizing cooling tower is driven to solve the problems, such as cooling tower invisible waste electricity using the hydraulic turbine in the utility model
Reduce cooling tower simultaneously to float water.It is given and is supplemented using Intelligent pressure unit while power surplus deficiency, keep system more than needed
Energy is fully utilized.Implementation process is as follows:
(1) hydraulic turbine drives intelligent atomizing cooling tower to be arranged in cooling tower using modular combination mode.Recycle water mist
It is 5 meters that required pressure head is set in makeup, and water wheels compressing head needed for the hydraulic turbine drives intelligent atomizing cooling tower is by the practical pressure more than needed of system
Pressure head needed for head situation subtracts atomising device, the minimum design head of the hydraulic turbine is based on 10 meters, as hydraulic turbine actual ram is lower than
It 10 meters, is then supplied using freq uency conversion supercharging device, the hydraulic turbine, the branch where freq uency conversion supercharging device is then bypassed to higher than 10 meters
Road water inlet pipe is closed.This project is individually atomized push unit and designs by 100m3/h, and specific flow can increase and decrease according to the actual situation.
Hydraulic turbine actual design pressure head=system return pressure head-hydraulic turbine drives intelligent atomizing cooling tower-atomising device institute
Pressure head is needed, such as hydraulic turbine actual design pressure head >=10 meter, is then designed by actual ram；Such as hydraulic turbine actual design pressure head < 10
Rice, then supplied by supercharging device, is designed by 10 meters.
This project hydraulic turbine is had more than needed -6 meters -5 meters=8 meters of pressure head=19 meter
19 meters: for backwater pressure head；
6 meters: hydraulic turbine atomising device mounting height is installed on 1 meter of air inlet top left-right position；
5 meters: pressure head needed for hydraulic turbine atomising device；
Because hydraulic turbine pressure head of having more than needed only has 8 meters, 10 meters are supplied using freq uency conversion supercharging device,
The practical acting P=ρ × g of the hydraulic turbine × Q × H ÷ 3600 × η hydraulic turbine
=1.0 × 103 × 9.81 × 100 × 10 ÷ 3600 × 88%
=2.398kW
ρ: for the density (1.0 × 103kg/m3) of water；
G: for acceleration of gravity (9.81m2/s)；
H: for pressure head (m) more than needed can be used in system；
η: turbine efficiency (%)
To make cooling tower play preferable cooling effect, the hydraulic turbine drives intelligent atomizing cooling tower gas-water ratio to design by 1.3,
And by the air quantity and wind pressure of gas-water ratio design the rotated fan blade of the hydraulic turbine, selected according to actual air quantity, wind pressure and Design of Rotation
Blower needed for fan blade.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 the blower of fan blade is directly driven by the hydraulic turbine, rotation speed of fan is identical as rotational speed of water turbine, the hydraulic turbine it is defeated
Power is the input power of blower out, so the fan pressure of fan blade can be obtained by power of fan formula inverse, it may be assumed that
The fan pressure of fan blade=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
By the calculating to system capacity, and the hydraulic turbine is designed according to calculated case and drives intelligent atomizing cooling tower air water,
Including the hydraulic turbine, the blower of fan blade, atomising device, control system etc..By to actual operating data before and after Revamping Cooling Tower
