Compared with conventional air forced cooling tower, the operational energy consumption of the cooling tower is reduced greatly, and the cost of production is saved.
Description
Technical field
The utility model relates to a kind of cooling tower, relates in particular to a kind of natural air exhaust formula energy-saving cooling tower that does not have blower fan.
Background technology
The development of coastal industry constantly increases the demand of cooling water, and the discharge capacity of cooling water is increasing.If cooling water directly to ocean disposal, will cause serious thermal pollution to the ocean.Clearly stipulate in " People's Republic of China's marine protection method ": to marine site discharging heated waste water, must adopt an effective measure, guarantee that the water temperature of contiguous fisheries water meets the national marine environmental quality standards, avoid the harm of thermal pollution aquatic resources.Therefore, cooling tower is its requisite vitals in the industrial cycle water system.Cooling tower is that air-cooled, present cooling tower mostly adopts blower fan to carry out the exhausting cooling mostly, and shortcoming is that energy consumption is higher, and production and operating cost increase relatively.
The utility model content
The technical problems to be solved in the utility model is: for the shortcoming and the deficiency that overcome prior art, the utility model provides a kind of no blower fan energy-saving cooling tower.
The technical solution adopted in the utility model is: a kind of no blower fan energy-saving cooling tower, has body of the tower, be disposed with packing layer, water distribution system and water collection device by from lower to upper order in the body of the tower, include a plurality of bleed upper-spraying type shower nozzles in the described water distribution system, the body of the tower downside is provided with air-inlet window, and the top of body of the tower is provided with at least one air duct.
Described its spout of bleed upper-spraying type shower nozzle up and the spout position be provided with the bleed device.
Described water collection device by some erect-type, mutually side by side and the arc water collecting piece that is provided with at interval form, on two windward sides of every arc water collecting piece, be provided with the muscle that blocks water at least together.
Say that further in order to reach the harmony of high water resistant rate and low-flow resistance, the muscle that blocks water on two windward side of described arc water collecting piece respectively is provided with 2 roads, and also is provided with the muscle that blocks water together in the summit position of arc water collecting piece.
The resistance of air-flow when square body of the tower carries out the transition to circular air duct in the tower makes the whole air distribution of tower on the cross section more even simultaneously when reducing exhausting, and the air duct at body of the tower top evenly is provided with 4.
The beneficial effects of the utility model are: this cooling tower does not use blower fan to carry out exhausting, but relies on himself structure to carry out the cooling of natural air exhaust formula, and its operation energy consumption of more conventional mechanical force cooling column reduces greatly, has saved production cost.

The specific embodiment
A kind of no blower fan energy-saving cooling tower as shown in Figure 1, has body of the tower, be disposed with packing layer 1, water distribution system 2 and water collection device 3 by from lower to upper order in the body of the tower, include a plurality of bleed upper-spraying type shower nozzles in the described water distribution system 2, the body of the tower downside is provided with air-inlet window, and the top of body of the tower is provided with at least one air duct 4.Its spout of bleed upper-spraying type shower nozzle up and the spout position be provided with the bleed device.Water collection device 3 by some erect-type, mutually side by side and the arc water collecting piece that is provided with at interval form, on two windward sides of every arc water collecting piece, be provided with the muscle that blocks water at least together.
In order to reach the harmony of high water resistant rate and low-flow resistance, the muscle that blocks water on two windward side of arc water collecting piece respectively is provided with twice, and also is provided with the muscle that blocks water together in the summit position of arc water collecting piece.
The resistance of air-flow when square body of the tower carries out the transition to circular air duct in the tower makes the whole air distribution of tower on the cross section more even simultaneously when reducing exhausting, and the air duct 4 at body of the tower top evenly is provided with 4.
No blower fan energy-saving cooling tower of the present utility model does not use blower fan, motor, and mainly is to carry out exhausting by the bleed upper-spraying type shower nozzle in its water distribution system when spraying.During operation, water sprays at a high speed from the shower nozzle delivery port, drives the gas flow in diffusing opening zone, make shower nozzle diffusing opening zone form certain negative pressure, air will enter shower nozzle from the tap air channel of shower nozzle spout bleed device, reach good atomizing effect, thereby improve cooling performance.The motion of air-flow also plays a part exhausting simultaneously, shows that by test this kind shower nozzle is under nominal situation, and the rate of air sucked in required of single shower nozzle can reach 1200m
3/ h can satisfy the air quantity demand of finishing the cooling task fully.Water forms the water droplet that particle diameter is about 1mm from shower nozzle ejection back, and through up and two processes that fall, big with the contact area of air, heat exchanger time is long; After water droplet is fallen packing layer, by filler it is cooled off again; Behind packing layer, water droplet carries out a heat exchange again in the rain belt.Through above three road cooling procedures, can fully guarantee the cooling performance of cooling tower under nominal situation.
The employed water collection device of this cooling tower detects department's on-the-spot test via national authority and shows that this water collection device is received water efficient, and its water loss that wafts can reach below 0.001% by quantity of circulating water, and gas-flow resistance simultaneously is very little, has reached advanced level at home and abroad in the like product.
The same model air duct of using on the air duct that this cooling tower uses and the conventional machine power tower is compared and has in height been improved a model rank, and adopt a plurality of air ducts evenly to arrange the arrangement form of establishing, the resistance of air-flow when square body of the tower carries out the transition to circular air duct in the tower makes the whole air distribution of tower on the cross section more even simultaneously when greatly reducing exhausting.Gas at first carries out the rectification first time by packing layer after flowing into tower, can be distributed to each corner in the tower equably to guarantee cold air, carries out the rectification second time by water collection device again before going out tower, guarantees that damp-heat air discharges outside the tower smoothly.
This cooling tower is the cooling of natural air exhaust formula, does not use power consumption parts such as blower fan, motor, so its more conventional mechanical force cooling column operation energy consumption reduces greatly, has saved production cost.This cooling tower extremely is suitable for using in the in line system of the cooling water of littoral industrial area.
