The utility model changes the principles and the modes of the traditional water cooling tower, and the traditional filling material blower tower is changed into a novel cooling tower without filling materials and electromotor blowers, so that the problems of the filling material such as the proneness of softening and the proneness of embrittlement under high temperature, and the updating maintenance after the softening and the embrittlement, moreover, the large-scale high-temperature water cooling tower is more suitable for the large-scale tower, especially for the cooling process of the high temperature water.
Description
Technical field
The utility model belongs to field of cooling, is a kind of water-cooling apparatus, a kind of large high-temperature water cooling tower of further saying so.
Background technology
The traditional water cooling tower all adopts reinforced plastic glass fibre to do filler, by water-locator water is drenched on the reinforced plastic glass fibre filler from top, utilize the motor fan on the cat head to carry out forced draft, wind enters in the tower all around from the tower bottom, approach reinforced plastic glass fibre filler then, in filler, carry out heat exchange with hot water, the heat after the exchange by motor fan outside tower is discharged on top.
Because the specification and the life-span of the motor fan of large glass steel cooling tower can't be satisfied user demand, the at high temperature softening easily and embrittlement of fiberglass filler simultaneously, produce the water distribution bias current after the softening and embrittlement of fiberglass filler, have a strong impact on the temperature drop effect of tower, the fiberglass filler is softening simultaneously needs the fillers that renew with embrittlement more after to a certain degree, increase the operation and maintenance cost of cooling tower.
Summary of the invention
The utility model is intended to the above-mentioned defective at existing glass fibre reinforced plastics cooling tower existence, a kind of large high-temperature water cooling tower is provided, change the principle and the mode of traditional water cooling tower, change the novel cooling tower that no filler does not have motor fan into by traditional filler blower fan tower, filler at high temperature easy and softening and embrittlement have been stopped, and the problem of the updating maintenance after softening and the embrittlement, and more be applicable to particularly high-temperature water cooling of Large Towers.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of large high-temperature water cooling tower, air duct is installed in the pylon upper end, it is characterized in that: the air duct lower end is provided with interior air duct, should in the interior air duct propulsive thrust rotation extractor fan be arranged, the fixed body that is connected with the rotary body bearing-type on comprising rotary body and being enclosed within rotary body, fixed body is connected with inlet channel, rotary body radially connects some shower nozzles, the nozzle of shower nozzle is arranged along the rotary body tangential direction, also be connected with the rotating vane of radial arrangement on this rotary body, a rotating body is provided with water stream channel, is communicated with the shower nozzle on top and the inlet channel of bottom respectively, and inlet channel is communicated with cooling water pump.
Described air duct is the screen cloth air duct, and sidewall is mesh-like.
Described screen cloth air duct top is provided with water collection device.
The fixed body of described propulsive thrust rotation extractor fan is connected through bush-type bearing with rotary body.
Described fixed body lower end is provided with the pipe connecting flange that is connected with inlet channel.
Be provided with dam nozzle and sealing ring between described pipe connecting flange and the rotary body.
Described screen cloth air duct bottom side is provided with return flume, and this return flume is connected with the water leg of pylon bottom through secondary water spray backwater pipe fitting, and this water leg is connected with the secondary cooling spray through distributive pipe.
The oblique top of the nozzle of described shower nozzle.
The utility model operation principle:
" the propulsive thrust rotation extractor fan " that bush-type bearing is housed adopted at this tower core position.
This device can atomize cooling water, and produces a large amount of wind (can follow in the tower body according to needs and requirement one or more rotation extractor fans are set).This device utilizes the hydraulic pressure that cooling water pump gives, and (0.08～0.14Mpa) as power, cooling water is by distributing in the pipeline access to plant, again from eight nozzle (vortex atomizing nozzle) ejections with certain angle and gradient, because cooling water has certain pressure, during the cooling water ejection device is produced certain propulsive thrust, impel device high speed Rotating with Uniform, the blade of being furnished with on the use device, make device in rotating spraying, carry out exhausting, under the condition of gas liquid ratio greatly, carry out the convection heat transfer' heat-transfer by convection mass transfer from a large amount of cold wind of the outside suction of cooling tower and vaporific hot water, the heat that cold wind is taken away in the water smoke is taken out of in the tower through the cooling tower top, makes the hot water cooling; Upward the cooled water smoke of spray is collected the back by the screen cloth air duct and is merged in the return flume simultaneously, collect in water in the tank in pipeline flows to the tower bottom distributive pipe, carry out the secondary spraying by fixed nozzle, introduce the outer cold wind of tower simultaneously once more and carry out the secondary cooling, make water temperature further be cooled off.
The utility model atomizing water cooling tower and material filling type cooling tower relatively have following advantage:
One, good cooling effect: the utility model is owing to be directly to carry out heat exchange under vaporific condition between hot water and the cold water, and heat-transfer effect is good, adds big cold blast rate (gas-water ratio reaches 1.0～1.2); Wind resistance is little in the tower, and the appropriate design of air channel and secondary spraying, thereby has the good cooling effect.
Two, water temperature is fallen stable: because the utility model adopts ejector principle to cool off, there is not the situation that filler stops up and blower motor damages, so the temperature drop effect stability.
Three, save the blower fan power consumption: the PCZ type spraying exhausting atomising device that the utility model adopts can form good vaporific and big exhausting amount under 0.08～0.14 work water pressure, satisfy the heat transfer and the air-conditioning requirement of tower, therefore utilize low-pressure pump to meet the demands, saved the power consumption of blower fan.
Four, noise is low: because the utility model adopts spraying exhausting atomising device, do not have motor fan and gearbox, so its noise is extremely low, less than 52db, is particularly suitable for hotel, restaurant and big city and requires the extremely low occasion of noise.
Five, the cooling water inflow of tower can be regulated: for the cooling tower of given model, the utlity model has work water pressure and change (being that flow changes) little substantially characteristic of the Inlet and outlet water temperature difference, therefore the cooling water inflow (in the allowed band of spraying extractor fan) of tower can be improved with the way that increases pressure of supply water, the temperature drop of tower can also be regulated simultaneously with the way that changes spray Zi, one of the lunar mansions aperture.
Six, maintenance capacity is few: the utility model adopts bushing bearing, utilizes water lubriucated bearing, only checks when making regular check on every year that tightness just can (need not resemble packed tower periodic replacement filler and maintenance reduction box).
Seven, the tower body weight in wet base is light: alleviated Base Design requirement and mounting cost.
Eight, no filler: water can not produce bias current, does not produce broken filler and stops up the water pipe phenomenon, does not have high-temperature water to soften the filler phenomenon.
