Description
Technical field
The utility model relates to evaporative heat loss device cooling tower field, particularly a kind of hydrodynamic(al) blower fan energy-saving cooling tower.
Background technology
Cooling tower is to be circulating coolant with water; Carry out cold and hot exchange after utilizing water and air to flow contact and produce steam, the steam volatile zone is walked heat and is reached principles such as evaporative heat loss, convection heat transfer' heat-transfer by convection and radiant heat transfer and leave in the industry or the waste heat that produces in the refrigeration air-conditioner reduces the evaporative heat loss device of water temperature.Mainly deciding by heat-exchange capacity of cooling tower by gas-water ratio, the hot water of how many mass flows carries out the expection temperature drop that heat exchange can realize cooling tower with the air of how many mass flows, and its moving air generally adopts the motor-driven fan blade to obtain.
The shortcoming of electric fan cooling tower is that maintenance is frequent, needs the lubrication circumstances of running check motor, and when motor bearings lost efficacy, maintenance difficulty was big, expense is high; Upper shift of gravity center, the weight of tower are big, therefore require the intensity of tower body high, further increase manufacturing cost; The motor oscillating noise is bigger, and motor often influences cold effect because of belt creep in addition.
Summary of the invention
The purpose of the utility model provides a kind of hydrodynamic(al) blower fan energy-saving cooling tower, overcomes the deficiency of prior art, utilizes the head more than needed of recirculated water to drive hydraulic turbine drive fan blade; Strengthening air flows; Realize cooling heat transferring, reduce the tower body vibration noise, prolong cooling tower service life.
For solving the problems of the technologies described above, the technical scheme of the utility model is:
Hydrodynamic(al) blower fan energy-saving cooling tower comprises tower body, fan blade, water-locator and heat radiation filler, and said fan blade is arranged on the hydraulic turbine output shaft, and hydraulic turbine water inlet links to each other with water inlet pipe, and hydraulic turbine delivery port links to each other with water-locator.
The water inlet pipe at the said hydraulic turbine upper reaches is provided with the dividing potential drop pipe, and the dividing potential drop pipe is provided with control valve, and the outlet of dividing potential drop pipe links to each other with water-locator.
The said hydraulic turbine is a crossflow turbine.
Compared with prior art, the beneficial effect of the utility model is:
1) utilizes the tower hydraulic drives hydraulic turbine to replace the driven by motor fan blade, saved the operation power consumption of blade motor fully.
2) power conversion of the hydraulic turbine is accomplished in runner, has got rid of cooling tower mechanokinetic noise source, has solved the complaint of people to the cooling tower electric machine noise.
3) resistance of hydraulic turbine 0.5m does not only influence the flow of pump in pump lift, shaft power of water turbine reaches blade shaft power can satisfy the driving requirement, need not resemble to have more the deficiency that some power are dealt with starting current the motor.
4) hydraulic turbine structure is simple, safeguard and change conveniently, but long-term operation does not have damage.
5) do not have electric spark to produce, be particularly useful for the high-risk explosion-proof place of web rot and use.

The specific embodiment
Be described further below in conjunction with the specific embodiment of accompanying drawing the utility model:
Seeing Fig. 1, Fig. 2, is the utility model hydrodynamic(al) blower fan energy-saving cooling tower example structure sketch map, and embodiment is two blade structure cooling towers; Comprise tower body 1, air duct 2, fan blade 3, the hydraulic turbine 10, water-locator 4, cloth (operating) water nozzle 5 and heat radiation filler 6; Heat radiation filler 6 belows are water-collecting tray 7, and delivery port 8 is positioned at the bottom of water-collecting tray 7, and 1 liang of side lower part of tower body is provided with shutter 9; To increase ventilation area; Fan blade 3 is arranged on the hydraulic turbine 10 output shafts, and the hydraulic turbine 10 water inlets link to each other with water inlet pipe 11, and the hydraulic turbine 10 delivery ports link to each other with water-locator 4.Hydrodynamic(al) blower fan cooling tower is exactly to make full use of the energy of tower head into to reach purpose of energy saving.
The tower head that advances of cooling tower is generally 5-8m, shows according to statistics, and the tower head that advances that each manufacturer sets differs greatly.The tower hydraulic pressure that advances of Large Towers often surpasses 10m, advances the tower head and is the water distribution service, reaches a suitable ratio in order to make air mass flow and the hot water flow that needs heat radiation; The rotating speed that needs the adjustment hydraulic turbine 10; On the water inlet pipe 11 at the hydraulic turbine upper reaches, be provided with dividing potential drop pipe 12, dividing potential drop pipe 12 is provided with control valve 13, and the outlet of dividing potential drop pipe 12 links to each other with water-locator 4; Adjust the aperture of control valve 13, just can regulate the rotating speed of the hydraulic turbine 10.
The hydraulic turbine 10 is a crossflow turbine.Hydraulic turbine main working parts is an impeller, and current have Free Surface between the double click type impeller, can not produce cavitation erosion to impeller, can increase the service life; Current do not have pressure reduction before and after the impeller, and the conversion efficiency of energy is higher; Adaptive capacity is better when current change greatly.
The motor power consumption of present cooling tower coupling, national Specification is that the standard tower is calculated less than 0.06kW/t less than 0.04kW/t, middle temperature tower.After using the hydraulic turbine instead and driving fan blade, need not consider the motor coupling again, only take into account that the shaft power whether the tower head reaches fan blade get final product, need only the rated value that shaft power reaches fan blade, just can reach specified cooling effect.
