Description

TECHNICAL FIELD

[0001] The utility model relates to public water cooling technical field, especially a cooling tower. BACKGROUND

[0002] At present, the water tower on the market except the natural draft cooling tower used in the thermal power plant generally adopts two ways for the industrial and commercial water cooling demand, one is open cooling tower, the other is closed cooling tower, the open cooling tower is applicable to some industrial cooling demand with low requirement to the water quality after cooling, the closed cooling tower is applicable to the direction with high requirement to the water quality after cooling, but both have the same shortcomings, first, the heat exchange efficiency cannot reach the local air wet bulb temperature (here refers to the closed cooling tower, the main reason is that the cooling water is sprayed from top to bottom, according to the thermodynamic principle, the coldest water vapor should be cooled from the outlet position of the cooled water, but the closed cooling tower can only adopt the top-down cooling mode, and the open cooling tower can only approach the wet bulb temperature because it needs to avoid the large amount of water mist drift loss caused by high negative pressure, thus the fan operation speed is reduced. Second, except for the dry cooling tower (when the closed cooling tower does not use cooling water but adopts air cooling, it can be called dry cooling tower, the closed cooling tower can usually adopt this mode for cooling during the ice formation period in winter), there is water drift loss, which cannot be ignored and avoided for the evaporative water cooling tower. At the same time, the drifted water also takes away the latent heat value of evaporation, so that the water cooling efficiency cannot be improved. Third, both water cooling towers need to regularly treat the cooling water (directly contacted with the environment) because the water used for cooling is continuously circulated and evaporated in the cooling tower, so the impurities will accumulate, not only forming scale, but also adsorbing a large amount of dust, thereby causing negative effects on the cooling water pipeline, and the scale on the filler and the cooling water pipeline also needs to be regularly cleaned. At the same time, various bactericides and anti-scaling agents are added to the cooling water during use, when the concentration of these used water reaches a certain degree, it needs to be drained. The drained water is directly discharged into the sewer, which will pollute the natural environment, and the neutralization and treatment of the polluted water will also increase the cost. The drained water also means that these water cannot participate in the evaporation heat exchange. The cold water of the closed cooling tower is from top to bottom whether the air is from both sides or from the upper part, so the heat exchange efficiency of the relatively cold upper water is not high. Therefore, the inventor designs a cooling tower with high heat exchange rate. SUMMARY

At this time, the controller opens the electromagnetic valve, and the evaporative water is injected. When the water collecting pool high level sensor monitors that the water level is up to a certain extent, the controller closes the electromagnetic valve, and the evaporative water stops being injected.

[0066] The water curtain can better absorb the dust in the air through adsorption, thereby reducing the overall maintenance frequency of the water tower and reducing costs.

[0067] The water curtain can be reused for a long time, and the replacement cost is also lower, the replacement is more convenient, and the maintenance no longer needs professional personnel to go to the door for maintenance, reducing the labor cost of maintenance.

[0068] Further simplify the structure of the cooling water tower, reduce the production and maintenance cost of the water tower.

[0069] A large number of the same structural components can reduce the batch cost.

[0087] Preferably, the drift prevention water curtain element mainly absorbs the splashing water beads from the inside of the main evaporation water curtain due to the air suction, and evaporates by capillary action.

At this time, the controller opens the solenoid valve, and the evaporation water is injected. When the high water level sensor detects that the water level is too high to a certain extent, the controller closes the solenoid valve, and the evaporation water stops being injected. The two low water level sensors and high water level sensors in the water collecting pool are located at the low water level and the high water level respectively.

[0095] It should be noted that compared with the prior art, the following advantages are achieved: the condensed water and part of the water used for evaporation can increase the air humidity to close to 100% through the water curtain, and at the same time, according to the size of the negative pressure air extraction force, the wet air can be reduced to the wet bulb temperature and below the wet bulb temperature. This cannot be achieved by the existing cooling water tower.

[0096] High humidity air can reduce the evaporation of open cooling water, but at the same time, it can also improve the air heat exchange efficiency, greatly reducing the amount of special cooling water and reducing pollution.

[0097] The air with the temperature equal to or lower than the wet bulb temperature, the air blowing from bottom to top and the internal cooling water circulating from high to low can make the water outlet end obtain a lower temperature than the prior art.

[0098] For the existing cooling tower, the spray system is removed, and high-permeability material is used to permeate flowing water, so that no small water droplets are generated.

[0099] The water curtain can better absorb dust in the air through adsorption, thereby reducing the overall maintenance frequency of the water tower and reducing costs.
