The specific embodiment
Below in conjunction with preferred embodiment of the present utility model the utility model is described in detail.
Fig. 1 has described the schematic main structure chart of cooling tower of the present utility model.Wherein cooling tower comprises: tower body 11, be installed in the blower fan 1 of tower body top, and the shower water cooling system is used for horizontal gas flow is converted into the air conducting grid 12 of uprush, is used to control the control system (not shown) of shower water cooling system switch.
Described shower water cooling system comprises recirculated water inlet 7, circulating water outlet 5, finned-tube bundle 4, water leg 13, cooling water circulating pump 10, circulated sprinkling bath water pipe 6, shower water distributor 3.
Wherein, recirculated water just needs the medium that is cooled, and finned-tube bundle 4 is a heat radiating fin structure, and shower water is the cooling medium that is used for cooling circulating water.
The operation principle of shower water cooling system is: the recirculated water that need be cooled 7 enters cooling system from entering the mouth, and discharges from exporting 5 through tortuous circulating water channel.In this course, recirculated water is by finned-tube bundle 4 release heat.Shower water is ejected into finned-tube bundle 4 by shower water distributor 3 simultaneously, has heat from finned-tube bundle 4, and further drops to the water leg 13 of cooling tower bottom.Water leg 13 lower left corners are installed with the shower water circulating pump 10 that has filter screen.Water in the water leg 13 is pumped to shower water distributor 3 by pump 10 via circulated sprinkling water pipe 6 after the net filtration after filtration, thereby realizes the circulation of cooling medium.
In addition, cooling tower of the present utility model also comprises water fender 8.Water fender 8 is arranged on air conducting grid 12 tops, flows out from air conducting grid 12 to prevent to spray the cooling water that gets off, thereby avoids the waste of spraying cooling water.
Cooling tower also comprises air conducting grid 12, and air conducting grid 12 have adjustable angle, the beam wind from the tower body side can be converted into vertical wind, thereby reduces the energy consumption of blower fan.
Cooling tower of the present utility model comprises that also the shower water that is arranged on the water collection device 2 between shower water distributor 3 and the blower fan 1 and is arranged in the water leg 13 replenishes the mouth of a river 9.Water collection device 2 can condense steam, then it is turned back to water leg 13.Along with the operation of cooling tower, the water of consumption can replenish the mouth of a river 9 by shower water and be replenished.
In addition, though clearly do not illustrate in the drawings, cooling tower of the present utility model also can comprise air velocity transducer and/or temperature sensor.Air velocity transducer and/or temperature sensor can become one with cooling tower, it also can be an independent devices, they can (for example pass through the data wire mode by current known variety of way with detected air speed data and/or temperature data, or wireless mode) be sent to the control system of cooling tower, this control system is controlled the Kai Heguan of shower water cooling system by analyzing above-mentioned air speed data and temperature data.
Come to analyze particularly the method for operating of cooling tower of the present utility model below.Described control system for example can comprise memory cell, processing unit.Processing unit compares analysis with the air speed data and/or the temperature data that receive and the wind speed setting value and the desired temperature that are stored in advance in the memory cell.
For example, the wind speed setting value of supposing to be stored in the memory cell is 6m/s (corresponding wind scale is about 4 grades), if the detected wind speed of air velocity transducer is greater than 6m/s so, then control system is closed the shower water cooling system, thereby current cooling tower is in pure air-cooled mode of operation.Otherwise, then open the shower water cooling system, make cooling tower be in water-cooled-air-cooled compound mode of operation.
Again for example, the desired temperature of supposing to be stored in the memory cell is 15C, if the detected Temperature numerical of temperature sensor less than 15C, then control system is closed the shower water cooling system, thus current cooling tower is in pure air-cooled mode of operation.Otherwise, then open the shower water cooling system, make cooling tower be in water-cooled-air-cooled compound mode of operation.
In addition, the control of cooling tower of the present utility model can also be carried out by the mode of measuring mean daily temperature and/or per day wind speed.
For example at northern area, winter, the early spring and late autumn the temperature step-down, it is big that wind-force becomes.At this moment, can be for example among one day, measure primary air velocity and/or temperature in each 2 hours, processor calculates 12 air speed datas recording within one day 24 hours and/or 12 temperature datas and tries to achieve mean value, again with memory in the value of setting that stores in advance compare, determine to open or close the shower water cooling system according to comparative result, thereby set up different cooling tower mode of operations.This calculate comparison procedure and example mentioned above similar, repeat no more herein.
In addition, blower fan 1 can be a frequency conversion fan, and it can regulate power according to the wind speed numerical value that records, when for example wind speed is low, improves the rotating speed of blower fan 1, and wind speed is when higher, turns down the rotating speed of blower fan 1 or blower fan 1 cuts out.Frequency conversion fan can also detect the circulating water temperature value that obtains according to second temperature sensor that is provided with at circulating water outlet 5 places, regulates wind speed automatically, and the adjustable scope of wind speed is 8～10m/s, thereby further optimizes the energy utilization efficiency of cooling tower.
The utility model compared with prior art beneficial effect is: the utility model uses two kinds of operational modes, saves water resource to the full extent, and installs frequency conversion fan and air conducting grid, energy-saving and emission-reduction additional.Because the cooling water temperature that recycles is lower, can not produce phenomenons such as fouling, therefore in water leg, do not need to add the precipitation medicament, add a small amount of antiseptic, prevent that the breeding of microorganism from getting final product.The experiment proved that: compare with traditional water-cooling tower, the utility model is on the basis that does not increase energy consumption, and average of the whole year using water wisely 90% is compared with evaporative type cooler, water saving 50%, energy-conservation 50%.And cooling tower of the present utility model is optimized the performance of whole cooling system with respect to traditional cooling tower energy savings more effectively.
Below in conjunction with the preferred embodiments the utility model has been made detailed description.Yet above explanation only is to be used for explaining principle of the present utility model and to provide exemplary embodiment, is not to be used to limit scope of the present utility model.By to the studying carefully of above content, those skilled in the art can make various modifications and distortion to the utility model under the situation that does not deviate from essence of the present utility model and scope.All such modifications and distortion all should fall within the scope of the present utility model that is defined by claim.
