Technical field
The present invention relates to a kind of devaporizer, especially a kind of low leaving water temperature evaporative type cooler of injecting type that can guarantee water quality.
Background technology
Evaporative cooling equipment, particularly cooling tower have been widely used in mainly being used for reducing the temperature of recirculated water in all trades and professions at present.As a kind of evaporative type cooler-cooling tower mainly is exactly through evaporation and heat-exchange, promptly carries out heat exchange through air and water and reaches the purpose that reduces cooling water temperature.The structure of cooling tower is a lot, is divided into open type cooling tower and closed cooling tower according to the way of contact of water and air.Cooling water directly contacts with atmosphere in the open type cooling tower, exists cooling water to be prone to contaminated problem, and is obvious for the occasion inferior position that water quality is had requirement.Closed cooling tower then can well address this problem, but is prone to form incrustation scale on the coil pipe of closed cooling tower, increases the pipe external thermal resistance, influences heat exchange efficiency.Cooling tower in the market generally can only drop to cooling water temperature and be higher than 3～5 ℃ of wet-bulb temperature.Be difficult to meet the demands for the such leaving water temperature of some specific industry.Therefore, need a kind of operation under different mode, can reach low temperature more, guarantee that the injecting type of water quality hangs down the leaving water temperature evaporative type cooler.
Summary of the invention
The present invention will provide a kind of injecting type to hang down the leaving water temperature evaporative type cooler; This evaporative type cooler can not only move under different mode; And can effectively avoid causing the problem of heat exchange coil heat exchange efficiency reduction, and can reach the more leaving water temperature of low temperature because of the fouling of coil pipe outer wall.
For realizing above-mentioned purpose; Technical scheme of the present invention is: a kind of injecting type hangs down the leaving water temperature evaporative type cooler; Comprise filler, cooling water coil and blower fan, be characterized in: be provided with filler below the cooling water coil, connect the injected cool radiator cooler through water fender below the filler.
The injected cool radiator cooler comprises tank, water pump, water knockout drum, shower, nozzle, water collection device; Both sides are respectively equipped with shower above the tank; Shower is connected with tank with water pump through water knockout drum, and several nozzles are housed on the shower, is provided with water collection device in the middle of the injected cool radiator cooler.
The air intake blinds is equipped with in injected cool radiator cooler both sides.The cooling water coil upper/lower terminal connects inlet tube and outlet tube respectively.
The invention has the beneficial effects as follows:
Get into after water is pumped up by water pump in the tank and spray cooled region, the effect of process nozzle is atomized, and forms low-pressure area in nozzle; Under differential pressure action; Outside air gets in the cooler, thereby makes the directly temperature of evaporation reduction air of atomized water with the water generation caloic exchange that is atomized, and is lower than external atmosphere pressure at jeting area internal environment pressure; The wet-bulb temperature of air is reduced; And not having the direct atomized water that evaporates owing to gravity effect backflow return flume, treated air does not have the moisture of direct a little of evaporating to stay on the filler through filler in the air; The saturated cleaning that is cooled like this and got into the first half by the air of step-down and carry out heat exchange with heat exchange coil, thereby reach the purpose of the circulating water temperature reduction in the heat exchange coil that makes top.And it is through increasing power of fan, improve ventilation and cause inner high negative, thereby more thereby realize that a large amount of evaporations of injection water descend circulating water temperature on cooler top.Top coil pipe non flouling behaviour can not influence heat exchange efficiency so in addition, because air themperature reduces, recirculated cooling water can reach lower leaving water temperature in addition.Owing to be that closed water quality circulation is can be guaranteed naturally.
This cooler is when transition season and winter, and following injecting type device can directly be closed, and opens the injecting type system when requiring and satisfied not cooling at summer high temperature weather leaving water temperature, so just can reach purpose of energy saving.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Like Fig. 1, shown in 2, injecting type of the present invention hangs down the leaving water temperature evaporative type cooler, comprises water fender 7, filler 8, cooling water coil 9, blower fan 10, air intake blinds, injected cool radiator cooler 14 etc.
Be provided with filler 8 below the cooling water coil 9, filler 8 is following through water fender 7 connection injected cool radiator coolers 14.Air intake blinds 11 is equipped with in injected cool radiator cooler both sides.Cooling water coil 9 upper/lower terminals connect inlet tube and outlet tube 12,13 respectively.
Injected cool radiator cooler 14 comprises tank 1, water pump 2, water knockout drum 3, shower 4, nozzle 5, water collection device 6; Both sides are respectively equipped with shower 4 above the tank 1; Shower 4 is connected with tank 1 with water pump 2 through water knockout drum 3; Several nozzles 5 (Fig. 3) are housed on the shower 4, are provided with water collection device 6 in the middle of the injected cool radiator cooler.
By the water process shower 4 that water pump 2 extracts from tank 1, the effect entering injection apparatus 14 through nozzle 5 has certain pressure reduction owing to this is regional with the external world; Air is got in the cooler by the external world, with the water generation caloic exchange of atomizing, thus the temperature of reduction air; Air obtains precooling and step-down; And do not have the water of directly evaporation because tank 1 is directly got back in the gravity effect, and cooled air process water fender 7 under the effect of negative-pressure air fan 10, filler 8; A little does not have direct moisture evaporated to stay on the filler 8 in the air; Get into top heat exchange coil 9 zones then, heat exchange coil 9 non flouling behaviours and influence its heat exchange effect like this, thus reach the purpose of the temperature that reduces the recirculated cooling water in the heat exchange coil 9., improve ventilation and cause inner high negative through increasing the power of blower fan 10 on cooler top, thus more thereby realize that a large amount of evaporations of injection water descend circulating water temperature.Be lower than external atmosphere pressure at jeting area internal environment pressure, the wet-bulb temperature of air is reduced, better than the cooling-down effect of simple top negative-pressure air fan operation like this, and also water quality is can be guaranteed.
When being in transition season and winter, we can switch off the pump 2, directly let air get into top heat exchanging coil pipe 9 and carry out air-cooled.We open water pump 2 when summer high temperature weather, and that kind makes us take different running mode in Various Seasonal, can reach purpose of energy saving.
As shown in Figure 4, the nozzle 5 that adopts among the present invention can be a disclosed air inducing fluid jet nozzle among the Chinese patent CN200950023Y, and its effect is exactly to cause negative pressure region and air inducing.
