Detailed description of the invention
Below, in conjunction with specific embodiments this utility model is described in detail.
A kind of cooling tower hydrodynamic draught fan structure, its structure sectional view is referring to accompanying drawing 2, seat 11, speed adjusting plate 12, water proof rubber circle 13 and water seal 14 is supported including water wheels 7, water wheels housing 8, main shaft 9, rotating shaft set 10, axle sleeve, the side of water wheels housing 8 is provided with water inlet 15, water inlet 15 connects with the cooling water inlet pipe of cooling tower, and cooling water is imported water wheels housing 8, water inlet 15 rotates towards the wheel page of water wheels 7 with driving water wheels 7.Speed adjusting plate 12 it is provided with between water inlet 15 and water wheels 7, by the flow velocity of the adjustable angle water stream of regulation speed adjusting plate 12, and then the rotating speed of regulation water wheels 7.The bottom of water wheels housing 8 is provided with outlet 16, water wheels 7 are positioned at water wheels housing 8, the center of water wheels 7 is fixing with the lower end of main shaft 9 to be connected, water wheels 7 can rotate around main shaft 9, the upper end fixed cover of main shaft 9 is located in rotating shaft set 10, bearing holder (housing, cover) 10 is fixed on axle sleeve is supported on seat 11 by bearing 17 and main shaft 9 nested encryptions, rotating shaft set 10, and main shaft 9 connects and drives blower fan (not shown).The three-dimensional structure diagram of water wheels 7 is referring to accompanying drawing 3, and the broken section structure chart of water wheels 7 is referring to accompanying drawing 4.
Cause getting rusty for water inlet in preventing main shaft 9, bearing holder (housing, cover) 10, between main shaft 9 and bearing holder (housing, cover) 10, be provided with water proof rubber circle 13 be provided with water seal 14 between the center and main shaft of water wheels 7.
The design code that should determine according to the maximum of production technology water consumption per hour according to country's " Code for design of industrial recirculating cooling water treatment " circulating cooling water yield, there is certain power surplus in circulation.Power surplus is contained in water, and under same equal pressure, the water yield is big, and power surplus is the most.Hydraulic pressure is equivalent to electric moter voltage, the water yield is equivalent to current of electric.
In same system, the upper tower water yield of every cooling tower can regulate the upper tower water yield by the upper tower valve of regulation.Upper tower valve opening is the least, and this valve is the biggest to the back pressure of water.Hydrodynamic draught fan structure of the present utility model is by consuming pressure reduction acting, really be equivalent to a less large size valve of aperture, except for the difference that in acting, valve can not do work water wheels pressure, by analyzing, cooling tower enters the energy of tower current, in the case of Yi Ban, enter tower current energy more than needed and enough promote the operation of blower fan.The hydrodynamic draught fan structure of the present embodiment after tested, when cooling tower water inlet surplus water head be 1.2 2.3KG time, it is possible to meet promote water wheels requirement.This blower fan promoted by water wheels is particularly well-suited to large cooling column.The thermal energy exchange ability of cooling tower is mainly determined by gas-water ratio, and the hot water of how many mass flows carries out heat exchange with the air of how many mass flows can realize the expection temperature drop of cooling tower.No matter and air is how to obtain, general conventional motor drives blower fan to obtain, and drives if using water wheels instead, then the shaft power of water wheels is identical with power of motor can be realized.The structure of tower, profile, size, cooling principle all vary without.
In specific implementation process, the tower cyclic hydrostatic pressure that enters of cooling tower is usually 1.2-2.3KG.Thus can calculate that possessing hydraulic pressure in the current of cooling tower is the power entering tower discharge in 1.2-2.3KG correspondence accordingly.If the energy consumption of 100t/h standard tower is about 2.2kW, i.e. the actual axle power of the fan blade used by 100t/h standard tower is about 2.2kW, the also less than 2.2kW that fan efficiency is high, 200t/h tower is about 4.5kW, 1000t/h is about 22kW, and 4000t/h is about 90kW, the like.Owing to possessing such energy in existing cooling tower current under nominal operating conditions, the present embodiment make use of these energy just.
In the present embodiment, the requirement of the water inlet pressure head of cooling tower can determine according to the summation that the jet power of the line loss of tower, the height of tower and water distribution is jointly required.Wherein the pressure head only 0.5-1m needed for the jet power of water distribution is sufficient to.These operating pressures come from water circulating pump, and water pump lift type selection calculation is the height of cooling tower present position, pipe in line loss, elbow, the resistance of valve, and the summation of watering equipment resistance.The flow mouth of pump is mated by cooling tower nominal name, and as 100t/h tower i.e. mates 100t/h pump, 500t/h i.e. mates 500t/h pump.Pump lift is multiplied by flow and is the power that current are possessed, and the pressure entering tower water is 1.2 2.3m remaining after total (pumping) head deducts water system drag losses.The 1.2-2.3KG of this preciousness, is exactly based on water wheels and obtains.So only needing cooling tower to meet conventional design type selecting, can be replaced blower motor by water wheels completely, the motive power of totally unnecessary worry water wheels affects air quantity, cold effect not.And enough complete water distribution and other line loss by the overbottom pressure that water wheels are later.
The beneficial effects of the utility model are: provide a kind of cooling tower hydrodynamic draught fan structure, utilize the cooling water inlet of cooling tower to drive water wheels to rotate, and water wheels realize the flowing of blower fan function-driven air while rotating, have the advantage that
1. noiseless: hydrodynamic draught fan structural energy of the present utility model conversion completes in water flow passage；By controlling the Reynolds number of surging, make water wheels will not send the noise of interference.
The most efficient: water wheels directly drive blower fan by main shaft, blower fan output fan blade, it is not required to again by other decelerator etc., and the air quantity respective change along with the change of discharge, all-the-time stable is in preferable gas-water ratio.
3. service life is long: hydrodynamic draught fan simple in construction of the present utility model, smooth running, as long as therefore reaching design of material intensity and sealing, its life-span is long-term.Once being out of order, maintenance is the easiest, changes some standard components, and easier than the maintenance of motor reducer is many.
4. safety: cooling tower electric machine has electric leakage to hurt sb.'s feelings, the potential danger of spark blast, water wheels not electricity consumption, and light weight, high-rise working is no longer difficult for motor reducer is unloaded in lifting, adds the running environment safety of cooling tower.
5. it is suitable for: any type of cooling tower is all suitable for, is particularly well-suited to oversized cooling tower, the biggest more reliable.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
