Description
Technical field
The utility model relates to cooler, furthermore: relate to industrial large-scale cooling tower.
Background technology
As everyone knows, cooling tower is widely used in industrial circle and heavy construction Water cooled air conditioners, its operation principle is: the top that enters cooling tower from the next hot water of heat-exchange system, from top spray down, fully contact with the cold air that enters from tower bottom, heat is conducted to air, fraction hot water evaporator strip is walked heat, hot-air rises and overflows from cat head, thereby makes hot water obtain cooling.
In order to save occupation of land and to reduce cool tower cost, existing cooling tower generally has certain altitude, and cat head is equipped with air exhauster mostly strengthens cross-ventilation, and the middle part has ripple packing to increase the time of staying of hot water in tower to improve cooling effectiveness.There are very big relation the cooling effectiveness of cooling tower and cross-ventilation intensity and the time of staying of hot water in tower that sprayed: tower is high more, and the hot water time of staying is long more, and cooling effectiveness is high more, but can increase the energy consumption of heat-exchanger pump; Cross-ventilation intensity is high more, and hot water contacts abundant more with cold air, and cooling effectiveness is high more, but can increase the energy consumption of air exhauster; Ripple packing is installed at the middle part can strengthen air drag, increases the air exhauster energy consumption.
The cooling tower of integrated mill, cooling water inflow is big, long operational time, energy consumption height.Cooling tower will reach the cooling requirement, and the energy consumption of air exhauster, last water and return water system is necessary.
At present, cooling tower is undertaken energy-conservation by the method for operation of improving spray mode, nozzle structure, filling-material structure, last return water system and air exhauster mostly.Patent 200810027134.7 " hydropower self-cooling cooling tower " makes full use of the potential energy cooling hot water of hot water itself, has founded brand-new cooling tower structure, and cooling tower height and cost all decrease; This patent has been transferred to the potential energy of backwater on the blower fan, but the power that must strengthen back water pump could satisfy original requirement, and in fact, from whole system, this scheme is not energy-conservation.
Summary of the invention
The purpose of this utility model provides a kind of energy-saving cooling tower, is mainly used on the large-sized concrete framework cooling tower, reduces the energy consumption of existing scheme cooling tower.
The energy-saving cooling tower that the designer provides is by traditional tower body, upper hose, return pipe, and exhausting tube, air exhauster, water distributor, shower nozzle, fiberglass enclose curtain and form, the exhausting tube places the tower body top, air exhauster is installed in exhausting tube inside, and water distributor is connected with upper hose, and shower nozzle is installed on it; The tower body below is equipped with air inlet; Tower bottom is to receive the pond; Unlike the prior art be to also have in this cooling tower water droplet potential energy to reclaim machine, gearbox and support thereof; Water droplet potential energy recovery machine is installed in tower bottom, and its turning cylinder links with the gearbox that is installed in cat head; Gearbox is installed on the interior support of exhausting tube, and top is equipped with air exhauster on it.
Above-mentioned tower body is square or circular frame, and fiberglass encloses curtain and surrounds whole tower body.
Above-mentioned water droplet potential energy reclaims machine and is made up of support, paddle wheel and rotating shaft again; One end of rotating shaft is installed on the bearing of support, and the other end then links with gearbox; Paddle wheel is fan-shaped, is installed in the bottom of rotating shaft.
Operation principle is: the hot water through heat exchanger goes out from the top of tower spray through shower nozzle by upper hose and water distributor, the water smoke, the water droplet that spray and go out, forming big water droplet at the decline heat transfer process beats on the paddle wheel of water droplet potential energy recovery machine, the potential energy converting and energy of water droplet is the kinetic energy of paddle wheel, thereby push-jump axle rotation, so far, the potential energy overwhelming majority of water droplet is converted to mechanical energy, small part is converted to the receipts pond that heat energy is got back to the cooling tower bottom. and the mechanical energy of generation alleviates the load of air exhauster, reaches energy-conservation purpose.
The designer points out: cooling tower is made into circle, and the recovering effect of water droplet potential energy is square better than being made into; The recovering effect of the appearance obstruction shower nozzle that suitable water quality is relatively poor and the no filler cooling tower water droplet potential energy of filler is better than Packed; Gearbox must have certain speed ratio.
The water droplet potential energy that the utility model uses reclaims machine, and processing and fabricating is simple, and investment is little, can replace the air exhauster motor of traditional cooling tower or the power of reduction air exhauster motor, thereby reach energy saving purposes.
