Abstract
The utility model discloses a blow and jet type cooling tower. A blower and an electrical machine are additionally arranged on the basis of the existing jet type cooling tower. A variable-frequency speed regulating device is electrically connected with the electric machine, and a temperature sensing controller is arranged on an outlet pipe and electrically connected with the variable-frequency speed regulating device. Temperature of the outlet pipe is sensed by the temperature sensing controller, a signal is transferred to the variable-frequency speed regulating device which controls rotary speed of the electric machine, and thus ventilation volume is automatically regulated following size change of load of a cooling tower. The best energy saving effect can be realized and the utility model accords with noise requirement of environment, and operation is very convenient.
Description
The utility model relates to the cooling tower in the air-conditioning equipment, especially a kind of blasting jet formula cooling tower.
Existing cooling tower carries out heat exchange and generally adopts force ventilation to broadcast the trickle mode, is about to system's hot water and broadcasts pouring on filler, and blower fan is with cooling medium---and air blows to filler, carries out heat exchange between system's hot water and air.Its draught capacity is owing to limited by the fixed rotating speed of 50HZ fixed frequency motor, and after design was supporting, its ventilation just can not change.This heat exchange method effect is relatively poor, and ventilation can not change with the load variations of refrigeration system, both wastes energy, and does not meet environmental requirement again.In order to make between system's hot water and air heat exchange more abundant, a kind of spray-type cooling tower has appearred again at present, it has increased the hydraulic pressure of water inlet pipe, make the water of nozzle ejection be vaporific, make water and gravity flow air carry out heat exchange, but flow owing to only depending on nozzle ejection water to drive air, the flowability of air is poor, influenced heat exchanger effectiveness, and increase hydraulic pressure makes also the power consumption of cooling system increase.
The purpose of this utility model is to provide a kind of blasting jet formula cooling tower that adopts electric power ventilation and ventilation to change with the variation of cooling tower load.
The utility model comprises tower body and is positioned at nozzle, the water collection device of tower body, water inlet pipe is communicated with nozzle, outlet pipe is communicated with tower body, the blower fan of translator also is set in the tower body, between blower fan and nozzle, current divider is arranged, variable-frequency governor is connected with motor, and temperature sensing controller is contained on the outlet pipe, and is electrically connected with variable-frequency governor.
During use, need system's hot water of cooling to enter, vaporific water all directions in tower are sprayed by nozzle from water inlet pipe.Owing to adopt flowing of the interior air of blower fan accelerated tower, so the required hydraulic pressure ratio of the water inlet pipe required hydraulic pressure of spray-type cooling tower in the past is little, and can keeps heat exchanger effectiveness preferably equally.The current divider that is provided with between blower fan and nozzle allows air to flow through and water smoke is intercepted.This current divider is a prior art, and it has in Chinese patent 97246147.7 and relates to.Water water smoke in the tower compiles and is after the bulky grain shape, makes it drop down onto current divider by the gravity effect, is flowed out by outlet pipe after collecting.The temperature sensing controller that is installed on the outlet pipe senses leaving water temperature according to preset parameters, and by lead signal is conducted to variable-frequency governor, controls rotating speed of motor by variable-frequency governor again.If the air-conditioning system load is big, the leaving water temperature of cooling tower will raise, and this moment, variable-frequency governor improved motor speed, increased ventilation; Otherwise, when air-conditioning system load hour then can reduce ventilation.Ventilation was big when enforcement of the present utility model made cooling tower large load operation on daytime; And night during little load operation, ventilation is corresponding to be reduced, thereby reduces the running noises at night, compliance with environmental protection requirements.Because ventilation can change automatically with load variations, can also realize optimum energy-saving effect simultaneously.
Fig. 1 is the structural representation of an embodiment of the utility model.
As shown in Figure 1, a kind of blasting jet formula cooling tower of the present utility model, comprise tower body 1 and the nozzle 4, the water collection device 9 that are positioned at tower body 1, water inlet pipe 5 is communicated with nozzle 4, and outlet pipe 6 is communicated with tower body 1, tower body 1 bottom also is provided with the blower fan 3 of translator 2, blower fan 3 is positioned at nozzle 4 belows, between blower fan 3 and nozzle 4 current divider 10 is arranged, and variable-frequency governor 7 is electrically connected with motor 2, temperature sensing controller 8 is contained on the outlet pipe 6, and is electrically connected with variable-frequency governor 7.At tower body 1 top exhausting blower fan 3 is installed if nozzle 4 is arranged on tower body 1 bottom, is then need not to install additional current divider.
