The invention belongs to refrigeration air-conditioner plumbing technical field.
The present invention is with the motor fan of prior art cooling tower and water-locator unification, cancellation motor; Dependence liquid pump with the design of hydraulic turbine principle send pressure, and liquid is by the hydraulic turbine, by hydraulic turbine output transferring power.Make fan blade rotate produce air quantity, thereby make gas-liquid carry out a kind of device of caloic exchange, be characterized in that fluid power replaces machine power, no power consumption, noiseless, the nothing water that wafts is applicable to that square circular is reverse-flow, on rectangle cross flow cooling tower and the chemical tower.According to the principle of tower gas-liquid heat exchange, no matter gas is with which kind of form to supply with, as long as provide enough gas and liquid to carry out heat exchange.If, then can be designed to the feeder formed by the hydraulic turbine so the hydraulic turbine is separated with liquid distributor, be placed in tower inside and outside, stand, crouch, bow, face upward and pump, but change ten thousand times without leaving the original aim or stand, liquid distributor necessarily is arranged on the tail position of feed flow route.
The objective of the invention is to design the waft cloth liquid aspirator of water of a kind of simple and effective, no power consumption, noiseless, nothing.Be applicable to all turriforms, without motor exhausting fiberglass and metalwork, on the industrial civilian cooling tower and chemical tower that cement spare etc. are formed.
Be water wheel type turning spurt water device, patent No. ZL92244095.6 with the technology figure viewed from behind of the present invention; There is not the water cooling tower patent No. ZL93240012.4 that wafts; There is not the water turning spurt water device number of patent application 97230555.6 that wafts; Fly mad cold tower number of patent application 98324638.6; GB7190-1997 fiberglass reinforced plastics cooling tower.
Generally need the blower fan exhausting on machine power type cooling tower and some chemical towers, blower fan be by motor as driving, the related decelerator that has, the mechanical noise of generation are difficult to eliminate, environmental protection is more and more stricter to the requirement of noise; The electricity charge of motor are very considerable, and plan and control is calculated, and ten months the blower fan electricity charge can be purchased a new cooling tower again.
Hyperbolic natural-draft cooling tower does not have blower fan, and its principle is that the tower body height increases, and tower body is long-pending to be increased, and relies on hot-air to rise, and the bottom is inhaled people's cold air and carried out heat exchange, and its shortcoming is that cost is big, and floor space is big.
It is to utilize the pressure of water to make sprayer unit rotation and while exhausting that prior art does not have blower fan spray water cooling tower, water becomes droplet and Forced Air Convection is carried out heat exchange, and its shortcoming is not have filler, and heat exchange does not utilize, it is outer more that water smoke is taken tower body out of, and the water that promptly wafts is bigger.The characteristics of spray water cooling tower are that air fully contacts with fog near the segment distance of nozzle, and the caloic exchange is quite obvious, and cooling effect is very good.But surpass after the segment distance, fog freely collides at random, is mixed into bulky grain by granule, and increasing, weaken with the caloic transmission of air, and more and more, on the whole, the cooling effect of spray water cooling tower can ideal.Another shortcoming of spray tower is to form fog, must reduce the aperture of jet water outlet, and the water outlet aperture reduces to produce susceptible to plugging disadvantage.The spraying exhausting formula water cooling tower of its structure graph technical characterictic publication in " water supply and drainage " 98 years the 7th phase J2 advertisement.
The advantage that prior art does not have a water cooling tower that wafts is to have adopted not have the water turning spurt water device that wafts, and according to the waft reason of water of generation, fundamentally eliminates the water that wafts.But the power consumption of extractor fan motor, vibration, noise also exist weak point.
The objective of the invention is to design a kind of simple and effective, the waft cloth liquid aspirator of water of no power consumption, noiseless, nothing.Be applicable to all towers, without the motor exhausting, fiberglass and metalwork, the mixed structure industry that cement spare etc. are formed is on civilian cooling tower and the chemical tower.
Main technical schemes is as follows:
Structure working principle of the present invention is that the hydraulic turbine is set on feed liquid pipeline, and liquid produces power by the hydraulic turbine, drives the fan blade rotation by hydraulic turbine output shaft and produces gas, reaches the purpose of gas-liquid caloic exchange.
The present invention compares the useful effect that is had with background technology be (1) energy savings, power consumption ratio by the national standard cooling tower, the coupling of blower fan is minimum to be 4 kilowatts of electrical power of every 100T tower, the electricity charge that this 4 kilowatt motor changeed 10 months can be to purchase one 100T cooling tower again, the present invention has kept the advantage of not having the water that wafts, the supplementing water of having saved cooling tower.(2) rotation of motor, thing followed worry produces immediately, and its noise is the most formidable problem of environmental pollution, and the present invention cancels the environmental issue that motor does not just have noise later on; Kept the advantage of not having the water that wafts, the problem of the environmental pollution by water that do not waft.(3) the fluid power exhausting is the hydraulic drive fan blade exhausting of being sent here by liquid pump, and it is the rotating speed increase and decrease along with the increase and decrease of hydraulic pressure, and air quantity is increase and decrease thereupon also, so all-the-time stable is in optimum state after Installation and Debugging for gas liquid ratio of the present invention, cooling effect is best.(4) the cancellation motor has just been cancelled the destruction of mechanical oscillation to tower body, has prolonged the life-span of equipment.(5) thread such as equipment self-weight amount reduce, the convenience that maintenance is checked, and danger that reduces work high above the ground or the like all is useful.
Accompanying drawing 1 is wherein a kind of structure chart of the present invention.Liquid enters from central tube 8, through the radial-flow type hydraulic turbine 6 output torques to drive 3; Liquid enters the bailing bucket that liquid distributor 5 impacts liquid distributor 5 inside, generation horizontally rotates power, pass through liquid distributor 2 jets again to filler 7, form recoil strength, make liquid distributor 2 horizontally rotate cloth liquid simultaneously around central shaft, tail end at each liquid distributor 2 is coupled to each other into ring belt, accepts the power that the rotation of drive 3 facades is transmitted, and is superimposed on the direction of rotation of liquid distributor 5 liquid distributors 2; Blade 1 is settled on liquid distributor 2 tops, and when central horizontal was rotated, blade 1 rotated simultaneously at liquid distributor 2, produces the air quantity updraft.For making drive 3 rotate transferring power reposefully, its fulcrum is located on the tower body 4.The formation of the jet recoil strength of liquid distributor 2 as shown in Figure 2, liquid is by fluid hole, and horizonally projected jet forces jet direction downward by the outer baffle plate of pipe, guarantees not have the advantage of the water that wafts, obtain bigger horizontal recoil strength simultaneously, make gas-liquid counter current carry out sufficient caloic exchange.
Implementing major technique key of the present invention is:
