Description
Technical field
The utility model relates to field of air conditioning, relates in particular to the cooling tower field.
Background technology
In the prior art, widely used cooling tower is that outdoor air directly contacts with cooling water, and cooling water evaporation reduces water temperature in air.The key parameter of weighing the cooling tower performance is the leaving water temperature of cooling water, reaches in identical outdoor situation under the situation of equal cooling tower inlet water temperature, the water yield, and the cooling tower leaving water temperature is low more, and then cooling effect is good more.Existing cooling tower, outlet temperature generally can be higher more than 2 ℃ than inlet air dry-bulb temperature.Therefore how to reduce the leaving water temperature of cooling water, the cooling effect that improves cooling tower is a problem demanding prompt solution in the prior art.
The utility model content
At problems of the prior art and deficiency, the purpose of this utility model is to provide a kind of counterflow cooling tower of horizontal band precooling.Cooling water leaving water temperature of the present utility model is low, good cooling results.
In order to realize the foregoing invention purpose, the technical solution of the utility model realizes as follows:
The counterflow cooling tower of horizontal band precooling comprises adverse current vapor-water heat exchanger, first order filler, second level filler, third level filler, first order water pump, second level water pump, third level water pump, heat exchanger water pump, first order tank, second level tank, third level tank, first order spray equipment, second level spray equipment, third level spray equipment.Its design feature is, water pumps at different levels respectively with the water pump in the tanks at different levels of bottom to fillers at different levels top, through spray equipments sprays at different levels and descend.Third level tank is connected with cooling water inlet, third level tank is connected with second level tank through pipeline, second level tank is connected with first order tank through pipeline, first order tank is connected adverse current vapor-water heat exchanger and coolant outlet through piping respectively with the heat exchanger water pump, and the adverse current vapor-water heat exchanger is connected with third level tank through piping.
Discharge in above-mentioned pipeline and the water pump is less than the discharge in the water pump.
Because the utility model has adopted the means of precooling, adverse current, the cooling water temperature that draws cooling tower is reduced, given full play to the cooling capacity of air.The outlet temperature of the utility model cooling water can be lower than the wet-bulb temperature of inlet air.Like this, also just make the utility model on cooling effect, be better than prior art.
Description of drawings
Fig. 1 is a structure principle chart of the present utility model.
Specify the specific embodiment of the present utility model below in conjunction with accompanying drawing.
The specific embodiment
Referring to Fig. 1, the counterflow cooling tower of horizontal band precooling comprises adverse current vapor-water heat exchanger 2, first order filler I, second level filler II, third level filler III, first order water pump 6, second level water pump 7, third level water pump 8, heat exchanger water pump 9, first order tank 15, second level tank 16, third level tank 17, first order spray equipment 18, second level spray equipment 11, third level spray equipment 14.Water pumps 6,7,8 at different levels respectively with the water pump in the tanks 15,16,17 at different levels of bottom to filler I at different levels, II, III top, through spray equipments 18,11,14 sprays at different levels and descend.Third level tank 17 is connected with cooling water inlet 5, third level tank 17 is connected with second level tank 16 through pipeline 13, second level tank 16 is connected with first order tank 15 through pipeline 12, first order tank 15 is connected adverse current vapor-water heat exchanger 2 and coolant outlet 4 respectively through piping and water pump 9, and adverse current vapor-water heat exchanger 2 is connected with third level tank 17 through piping.Discharge in above-mentioned pipeline 12,13 and the water pump 9 is less than the discharge in the water pump 6,7,8.Filler has divided three grades among the figure, can divide more multistage.
When using the utility model, inlet air 1 elder generation's process adverse current vapor-water heat exchanger 2 is by pre-cooled.Air is successively from filler I at different levels, II, and III flows through, and carries out the wet exchange of heat with water.Airborne humidity increases, the evaporation heat absorption, and the temperature of water reduces.Air 3 through the afterbody filler is discharged in the ambient atmosphere.Cooling tower import cooling water flows through filler III at different levels successively, II, and the tank 17,16,15 of the bottom of I, temperature reduces gradually, is exported from tank 15 by water pump 9, and a part flows through heat exchanger 2, and another part flows into coolant outlet 4.The water 10 that flows through heat exchanger flows into tank 17 through piping at last, participates in circulation.In the running, the water in the tank 17 flows into tank 16 by pipeline 13; Water in the tank 16 flows into tank 15 by pipeline 12.
