Description of drawings
Fig. 1 is the low-temp cooling tower structural representation.
Fig. 2 is I place enlarged drawing in Fig. 1.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
the below is with the air-conditioning system example, that join with cooling tower is air-conditioner host F, this air-conditioner host has the cooling circulating water outlet pipe P1 that is connected with cooling tower and is connected to the cooling circulating water return pipe P2 of cooling tower bottom, air-conditioner host is cooling via cooling tower from cooling circulating water outlet pipe outflow air-conditioner host through the cooling water that heat exchange temperature raises, generally, from the water temperature of the water to be cooled of cooling circulating water outlet pipe 37 ℃ of left and right, and traditional cooling tower can only have water treatment to be cooled the level of 32 ℃ of left and right to water outlet, this is for air-conditioner host, this leaving water temperature can allow air-conditioner host consume more electric energy equally.
as shown in Figure 1, a kind ofly degree of approximation (degree of approximation=cooling tower leaving water temperature-wet-bulb temperature) can be contracted to the low-temp cooling tower of 1 ℃ of left and right, it has tower body 1, this tower body has one and is gone along with sb. to guard him by housing and form and for water-cooled cavity 2 to be cooled, described cavity contains cooled region and evaporation region, be provided with water spray system to be cooled between described cooled region and evaporation region, water-locator is common spray mode, described cooled region is provided with the packing layer that is positioned at the spray equipment bottom, water to be cooled is ejected in this structure via spray equipment and carries out heat exchange, packing layer is according to the size setting of cooled region, arrange along the cooling tower shell inwall, the temporary transient regional intercommunication that stops of cooling water that evaporation region and cooled region below do not occur is advisable, described evaporation region has an air outlet 3 and a fan 4 of the water smoke of cavity being derived tower body, air outlet is positioned at the top of cooling tower, fan has the effect of the water smoke after outside discharging heat exchange, the housing of described tower body is provided with two air pretreatment devices 5, air pretreatment device 5 can be symmetrically arranged in the sidewall of housing, this air pretreatment device has one and is gone along with sb. to guard him the air communication channel that forms by housing 50, whole device can be regular or irregular profile, the profile of rule is such as square, circular etc., this passage contains an arrival end 51 that communicates with the tower body external environment condition and a port of export that communicates with the tower body cavity, filler setting on the cooling tower inwall can arrange support at port of export place, local filler covers support, and the port of export arranges certain distance with the filler that is in same level, certainly, also can adopt the port of export is arranged network, filler directly is installed on this network, passage between arrival end and the port of export is provided with cooling device, for cooling device, carrying out cooling with the form that produces the cascade curtain is simple and the most economical and the most practical means.
Described cooling device contains: evaporative cooling module 53 and the spray module that coordinates the evaporative cooling module, the evaporation module adopts the passage interstitital texture that contains some spaces, such as filler etc., be convenient to passing through of sky G﹠W, and, help completing of heat exchange, the passage of air pretreatment device adopts linear type structure, is positioned at that the entrance point of passage and the port of export arrange local crowning and the cavity that holds that forms low-temperature receiver.
Referring to Fig. 2, described spray module has shower nozzle, be positioned at passage and as the water 55 of cooling source, water extraction is risen to water pump 54 and the spray piping that evaporative cooling module top sprays, shower nozzle roughly is positioned at the gap location of filler and passage, be evenly arranged above being positioned at filler, the low-temperature receiver that water is located immediately at passage holds cavity.
Described evaporative cooling module adopts cooling tower filler, the cross section of filler and the cross section of passage are unanimous on the whole, the assemblage gap that only leaves spray equipment gets final product, this gap should not be too large, otherwise, hot-air taps into into cooling tower by this part direct clearance can affect our cooling effect, the kind of filler is more, and what conventional means can obtain has: S ripple filler, step Trapezium oblique wave filler, some ripple filler, two-way ripple filler, bias ripple filler, the wrong filler of oblique, the sinusoidal wave filler of poor position formula.
The air pretreatment device also comprises: the inlet duct 52 of being located at passage, it is as the guiding mechanism of passage air-flow, extraneous air is constantly sucked the cavity of cooling tower in a steady stream, for inlet duct, can select fan, in the porch of passage, comparatively ideal is set, the support that fan is set in the porch can be completed layout.
for summer, air themperature is higher, air themperature is higher than the inflow temperature of cooling tower often, the contact heat-exchanging direction is that airborne heat passes to recirculated water, heat exchanging is disadvantageous, although evaporation and heat-exchange is greater than contact heat-exchanging, but the air quantity that blower fan produces is certain, therefore when environment temperature is higher, enter cooling tower and carry out water to be cooled very difficult further cooling under the impact of hot-air of cooling operations, and take this air pretreatment device, hot-air such as in the situation that 40 ℃ from arrival end by after the fan introduction channel, under the cooling exchange interaction of filler, water temperature can be reduced to 35 ℃, compared to without overcooled hot-air, its advantage is significant, adopt our low-temp cooling tower, 28 ℃ of wet-bulb temperature, the cooling tower leaving water temperature can drop to 29～30 ℃, about low 2 degree of leaving water temperature than common cooling tower, in the situation that the cooling water reduction is 1 ℃, air-conditioner host Energy Efficiency Ratio (COP) can improve 5～10%.In air-conditioner host refrigeration, the heat transfer of water and air is the forward heat exchange, and certain, we also can utilize reverse heat-exchange, and namely air is to the mode of heat transfer water energy saving in addition.
