Abstract
The utility model relates to a special non-pressure double-nozzle inclined strike type water turbine for a cooling tower, which comprises a rotating wheel, a main shaft, a bearing device, a casing, an upper cover plate, a water collection barrel, a nozzle I and a nozzle II, wherein the nozzle I and the nozzle II are arranged on the casing; a center line of the nozzle I and the nozzle II forms an angle of 22.5 degrees with the horizontal plane of the rotating wheel; and the rotating wheel is connected and fixed with the main shaft through a key, a nut and a lock plate. In the special non-pressure double-nozzle inclined strike type water turbine for the cooling tower, surplus pump lift of a water pump is transformed to speed of water flow which can be utilized by the non-pressure double-nozzle inclined strike type water turbine, so that the water turbine obtains output power and directly drives a draught fan to dissipate heat. The structure is novel and compact, the overall dimension of the water turbine is small, the discharge capacity of double nozzles is large, the adjustment performance of flow capacity is good, the running efficiency of the water turbine is good, and the designed inclined strike type rotating wheel is matched with parameters needed by the draught fan so as to ensure that the draught fan has excellent heat dispersion. The special non-pressure double-nozzle inclined strike type water turbine for the cooling tower replaces the traditional cooling mode that the draught fan is driven by an electromotor and a speed reducer to reach the purposes of energy saving, environment protection and low cost, and has wide application prospect.
Description
Technical field
The invention belongs to cooling tower energy saving hydrodynamic force apparatus field, and its core is to utilize circulating water excess pressure to become high-velocity flow kinetic energy by twin nipple to drive water turbine, replaces the power of motor as blower fan.
Background technique
The blower fan cooling system of traditional cooling tower is to adopt parts such as motor, transmission shaft, umbrella gear deviator, retarder, fan blade to form; Its complex structure, poor reliability, motor power consumption are big, the operation noise is big; Motor, retarder maintenance cost height.In sum, neither environmental protection is not energy-conservation again for traditional type of cooling of usefulness motor driving blower fan.
In view of present cooling tower adopts the dedicated water turbine that drives blower fan, performance, effect are all undesirable, and it is too little that main cause is that cooling tower is left the installing space of water turbine for, and height and Plane Installation size all have strict restriction; Employed hydraulic turbine outlet directly is connected with water-dispensing device, and the working state of water turbine is far from it with working condition in traditional water power plant, causes the flow by water turbine to reduce, and efficient descends significantly; Heat radiation requires to have determined the air horsepower of blower fan and the rotating speed of requirement according to blower fan, will with these parameter matching of blower fan, employed dedicated water turbine can only be the water turbine of low-specific-speed, and the existing at present as calculated performance parameter that is used for the low-specific-speed Francis turbine of high head does not still satisfy requirement.
Summary of the invention
The purpose of the invention provides the special-purpose no pressure double-jet mouth inclined-jet turbine of a kind of cooling tower, it is utilized the lift more than needed of water pump by water turbine, thereby make water turbine obtain output power, water turbine directly drives the blower fan heat radiation, replace traditional type of cooling that motor, retarder drive blower fan, reached energy-saving and environmental protection, purpose cheaply.
The special-purpose no pressure double-jet mouth inclined-jet turbine of cooling tower, its general structure comprises runner, main shaft, bearing means, casing, upper cover plate, dust-collecting bucket; Nozzle I and nozzle II are arranged on the casing.
The horizontal plane of described nozzle I and nozzle II center line and runner is 22.5 °.
Described bearing means comprises bearing cup, upper ball cover, and gland, upper bearing (metal) divides semi-ring, lower bearing, lower ball cover and oil pooling hood; Described gland, upper ball cover, upper bearing (metal), bearing cup, branch semi-ring, lower bearing, lower ball cover and oil pooling hood are located at the outside of main shaft successively, and gland is connected with upper ball cover, upper bearing (metal) is located in the bearing cup, upper ball cover is connected with bearing cup, bearing cup, branch semi-ring, lower bearing are connected with upper cover plate respectively with lower ball cover, and oil pooling hood is connected with lower ball cover.
Described runner is connected and fixed by key, nut and jam plate and main shaft.
The beneficial effect of the invention, the special-purpose no pressure double-jet mouth inclined-jet turbine of cooling tower, it is after lift more than needed (pressure energy) with the current in the cooling tower pipeline changes high-velocity flow (kinetic energy) into by two nozzles, 22.5 ° of water inlet limits that are mapped to the tilt-impulse type runner bucket of inlet angle with an optimum, flow out the current waterside that goes out from blade of flowing through behind the blade, inclined-jet turbine can farthest be transformed into mechanical energy to water, make the runner rotation, its main shaft directly connects with blower fan main shaft, drives the blower fan rotation.
Operation conditions is good: current are flowed through behind the runner, flow in the casing of sealing, are connected with water-dispensing device by four dust-collecting buckets.Move more than the free surface of water of rotary wheel of water turbine in casing, running state is the same substantially with the water power plant working state, therefore as the cooling tower hydrodynamic machine compare with the water turbine of other patterns bigger conveyance capacity is arranged, higher efficient and operation stability.
In the invention, employing is the twin nipple that the current pressure energy becomes water flow dynamic energy an innovation bright spot.It has strengthened the conveyance capacity of runner, has dwindled the pitch diameter of runner, has reduced the external dimension of whole device, and is easy to regulate flow by nozzle, and making it has optimum coupling with the required parameter of blower fan; When summer and winter, the required air quantity of cooling tower has bigger difference, inclined-jet turbine can be easy to the nozzle that varies in size by the replacing outlet diameter or adjust number of nozzle reach the purpose of regulating flow, makes the air quantity of blower fan reach the required requirement of Various Seasonal.
In the invention, core key technology is the vane type line of tilt-impulse type runner.According to runner diameter D
