Description
Technical field
This invention relates to a kind of circulating water cooling tower, relates in particular to a kind of parallel-counter flow jet flow duplex hyperbolic.
Background technology
In the last hundred years, cooling tower is at home and abroad on the market, the reverse-flow filler double-curve cooling column that extensive use is traditional, yet the development from nearly decades, the cold efficiency of every reverse-flow filler double-curve cooling column is difficult to keep and improve, and the easy fouling of filler during the operation of such cooling tower, resistance large, fouling appears and after cold effect descend obviously, operation expense is high; In recent years, by filling cooling tower being modified into the practice of jet cooling tower, product was in actual motion, energy-conservation, maintenance really improves, but also do not reach ideal effect, main cause be the fine liquid particles that ejects of jet water distribution system under the gravity-flow ventilation effect, the insatiable hunger air that enters the tower chamber is inhomogeneous, spray the little water droplet that rises and be combined into large water droplet, cause water droplet under action of gravitation, hurtle down, and can not evenly distribute, short time of contact with air, affected cold effect and improved.
Summary of the invention
The parallel-counter flow jet flow duplex hyperbolic that the purpose of this invention is to provide stable, the low maintenance of high, the cold effect of a kind of cold effect, energy-conserving and environment-protective.
The technical solution used in the present invention is:

Preferably, described multidimensional shape dehydrater adds flat sheet by multidimensional shape sheet and is bonded into the hexagon alveolate texture, and water rem oval is good, intensity is high, indeformable, service life is longer more than one times than common dehydrater.
Preferably, described scroll casing type ejector comprises that upper volute, lower spiral case, nozzle, bleed mouth, air-vent and water inlet form; Described nozzle arranges with the water inlet dystopy is vertical, described nozzle is double-decker, internal layer is water spout, outer is the bleed mouth, have some air-vents on the perisporium of bleed mouth bottom, this structure can make the water that is entered by water inlet enter double-deck nozzle after the volute body rotation, the water spout of internal layer is in the situation that the ventilation of outer air-vent, because water spout produces negative pressure in course of injection, have the air inducing function, increased air output in the tower, consist of the cracking of ejection water droplet and produce even fine liquid particles, the contact area of water droplet and unsaturated air is increased, thereby and the unsaturated air that enters through the rectifier hole fully carry out heat exchange, further improved cold effect;
Preferably, the concurrent-countercurrent running space that combines with unsaturated air for the jet water droplet between described multidimensional shape dehydrater and the jet water distribution system has guaranteed the attaching space of fine liquid particles and unsaturated air.
Preferably, described honeycomb is bonded the hexagon honeycomb molded body by many knee-pieces, play the air conducting effect, make air draught evenly enter the tower chamber, and to multidimensional shape dehydrater, evenly adverse current to rectifier carries out falling into collecting-tank after the secondary cooling under action of gravitation from the water droplet following current of ejector ejection.
The principle of the invention is as follows
From thermodynamic (al) angle, parallel-counter flow jet flow duplex hyperbolic and traditional adverse current filler double-curve cooling column all belong to wet cooling tower, the heat transmission is carried out in caloic exchange when mainly directly contacting by water and air, heat is passed to unsaturated air by water, water temperature is descended, air themperature rises, and water capacity increases, and enters atmosphere.
By thermodynamic argument as can be known, the temperature difference is the motive force of transmittance process, and the partial pressure of steam is poor then to be the motive force of matter exchange, evaporation and cooling, and the matter exchange plays a leading role; When parallel-counter flow jet flow duplex hyperbolic penetrates current by ejector, make the cracking of water bundle be refined into numerous little water droplets and the increase of unsaturated air contact area, add that the kinetic energy that penetrates water droplet directive tower chamber makes it contact fully and perturb with air-flow, be beneficial to the caloic exchange of aqueous vapor, accelerated the water droplet cooling velocity; When the water droplet following current of penetrating to dehydrater, flow to rectifier in the action of gravitation subinverse, carry out falling into collecting-tank after the secondary cooling, so that not to be the conventional filler tower simple is reverse-flow for whole caloic exchange process, but the combination of co-current flow and counter-current flow is different from traditional packed tower, and air-flow constantly perturbs in the tower chamber, increased the relative velocity of water droplet and gas-liquid contact area, the factor of these features has been strengthened the heat exchange efficiency of parallel-counter flow jet flow duplex hyperbolic transmission tower.
During the cooling tower operation, the saturated moist air in the tower is being mingled with numerous fine liquid particles, and under the effect of gravity-flow ventilation, the easy drift of fine liquid particles is outside tower, and both the loss quantity of circulating water affected again surrounding environment; The characteristics of multidimensional shape dehydrater: it is led the way and consists of unique hyperspace, and flowing resistance is little, and water rem oval is high, evenly is placed in below in the air duct, has improved the destabilizing factor of fluidised form in the tower chamber.
Described honeycomb is bonded the hexagon honeycomb molded body by many knee-pieces, make air-flow enter into uniformly the tower chamber, improved the destabilizing factor of fluidised form in the tower chamber, increased the relative velocity of gas-liquid contact area, water droplet evenly distributes, and obtains sufficient heat exchange with air.
Described scroll casing type ejector is comprised of scroll casing shape upper and lower casing, nozzle, bleed mouth, air-vent and water inlet, described nozzle arranges with the water inlet dystopy is vertical, nozzle and water inlet position be not on same vertical center line, water inlet offset nozzle center line, thereby enter the water generates eddy flow of nozzle ejection, make the cracking of water bundle be refined into numerous fine liquid particles, nozzle is double-decker, internal layer is water spout, skin is the air inducing mouth, have some air-vents on the air inducing mouth perisporium, nozzle produces negative pressure on every side in course of injection, have the air inducing function; Make water in course of injection, fully carry out heat exchange with unsaturated air, thereby raising heat exchanger effectiveness, because the negative pressure of jet generation, the extraneous unsaturated air of auxiliary suction, so parallel-counter flow jet flow duplex hyperbolic is compared with conventional counter-current hyperbola filling cooling tower, a same cooling tower, jet flow compound double-curve cooling column is higher than traditional cold effect of adverse current hyperbola filling cooling tower.
The invention has the beneficial effects as follows: stable, the low maintenance of high, the cold effect of cold effect, energy-conserving and environment-protective.
