Detailed description of the invention
Propose a kind of air cooling compressor having force ventilation and gravity-flow ventilation concurrently with circle or polygon tower structure, namely the base of described cooling tower is circular or polygon (preferably close to circle).Aerial cooler around tower structure bottom peripheral edge portion, preferably vertically locate along the base peripheral of cooling tower.
The upright unit of aerial cooler is so-called cooling triangle.Cooling triangle comprises two the cooling panels be angularly placed in firm steel frame.Triangle (i.e. triangular shape) cross section of framework ensure that the angle (about 60 °-50 °) between two aerial cooler panels, the 3rd side are unlimited for cooling air inlet or be equipped with shutter.
In order to provide force ventilation (force ventilation is pith in summer), application air-introduced machine and by its vertically horizontal layout, that is, air-introduced machine has horizontal axis.In other words, surrounding air is drawn through aerial cooler panel and the air after heating is blown into the inside of tower shell by blower fan.According to cooling triangle vertical extension, blower fan can only arrange in a row or be arranged to self arrangement many rows.Another kind may be do not utilize blower ventilation device cover cooling triangle whole length, particularly when do not have the region of the ambient air temperature of Extreme warm and tower structure very high and be enough to increase air plenum.In this case, if apply 2-channel air cooler (namely cross-counterflow formula connects) at cooling water side, such as, not two exhaust blowers but only an exhaust blower can be applied to the Lower Half cooling triangle.Then for the first half of aerial cooler, cooling-air stream causes only by natural ventilation equipment.
Blower fan and housing thereof are also by the steel-frame structure supporting of cooling triangle.Cool triangle via its steel-frame structure by being positioned at the triangle leg part supporting with triangular shaped corresponding 3 of described triangle.Triangle leg has lid, and described lid gets around heat-exchanger surface to avoid cooling-air till being distributed to the initial height in aerial cooler surface always.
The tower structure of substantially rounded shape can be structural steel with covering or Concrete Structure.Because tower structure is only used for increasing the cooling-air stream except force ventilation, therefore it is only highly preferably 2-4 times of the length of cooling triangle, therefore still far below the height of conventional gravity-flow ventilation tower.Tower structure needs the height of at least 2 times of the height had for cooling triangle can produce considerable gravity-flow ventilation.The diameter being vertically furnished with the roundel of cooling triangle is around greater than the diameter of the tower structure of the over top at cooling triangle usually.Therefore, tower structure has its own independent leg and supporting member, and has the lid broadened gradually between tower structure and the top of cooling triangle.But, when structure head tower, if to be positioned with the diameter of the roundel cooling triangle identical or correspond to each other for the diameter of tower structure and surrounding, then particularly advantageous layout can be realized.This provides following chance: will cool triangular steel framework---and namely, the cooling triangular frame structure simultaneously applied and its supporting leg---for supporting whole tower structure, this causes the significantly reduction of required material cost and infrastructure cost.
Have the region of freezing risk as already mentioned, the air inlet side of cooling triangle can have exterior shutter.For the region of extreme cold in winter, except cooling triangle inlet side, more shutter (namely at the inside shutter of warm air outlet side) can also be applied between the internal edge of adjacent cooling triangle.At perishing place place in order to avoid freezing risk, electric heater can be had between inlet louver and cooling triangle, being preferably heater grid.Heater only works under such extreme weather between the starting period.
Potential Advantageous embodiments of the present utility model is shown in Figure 1.The multiple cooling triangles 1 respectively comprising two aerial cooler panels are vertically arranged around the substantially rounded tower structure 2 of cooling tower 3.Tower structure 2 is made up of the steel construction or concrete with surface covering 6.The lid 13 broadened gradually is applied between tower structure and cooling triangle 1.The height of tower structure 2 is at least 2 times, preferably about 2-4 times of the height of cooling triangle 1.The gravity-flow ventilation caused due to such tower height degree is not enough to, for effective Air flow, also should use force ventilation.Blower fan 4 is positioned in perpendicular, and cooling-air 5 is drawn through cooling triangle 1 and cooling-air 5 is blown into the inside of air cooling compressor 3 by it.
The B-B profile of the Fig. 2 shown in Fig. 2 and Fig. 3 shows similar and embodiment advantageously of the present utility model.Tower structure 2 is steel frames of the approximate circle tubular in surrounding air side with surface covering 6.The special feature of the layout in Fig. 2 with Fig. 3 be to cool triangle 1 be almost arranged in identical with the diameter of tower structure 2 diametrically and the framework cooling triangle 1 thus is also almost arranged in diametrically identical with the diameter of tower structure 2.Therefore, supporting member and extension that triangular frame structure 7 is used as tower structure 2 is extraly cooled.Therefore, the supporting leg that triangle leg 8 is also used as whole cooling tower 3 is cooled.
Fig. 4 illustrates cooling triangle 1 and blower fan 4 positioned opposite.Also schematically depict the element (is known) of cooling triangular frame structure 7 itself.Have nothing to do with the type of tower structure, the relative position of cooling triangle 1 and air-introduced machine 4 and arrange to be similar for the tower of two shown in Fig. 1 with Fig. 2.But apply longer cooling triangle 1 in fig. 2, this can meet the application being positioned at blower fan 4 in perpendicular with self becoming three rows.
In two kinds of situations of Fig. 1 and Fig. 2, if tower structure is relatively high, then there is following chance: only utilize blower ventilation device to cover the bottom of whole length of cooling triangle 1, thus only apply single blower fan instead of two rows' (as shown in Figure 1) or three rows' (as shown in Figures 2 and 3).In these cases, the flowing flowing through all the other cooling triangular surface of cooling-air 5 is only caused by gravity-flow ventilation.
The import of the flowing for controlling (regulate, close or open) cooling-air 5---as a kind of common scheme---is equipped with in most cases, that is, exterior shutter 9.If risk is not freezed in the place at cooling tower 3 place, make an exception.But the region of extreme cold in the winter time, in order to avoid possible to freeze, freezing particularly between the starting period, as shown in Figure 5, not only can apply exterior shutter 9, and can apply additional inside shutter 10.Except applying dual shutter, cool and to be also positioned with electric heater 12 on exterior shutter 9 and aerial cooler surface, namely between panel 11, to be preferably electric heater net, this electric heater 12 activates within the coldest period during start-up routine.
Hereinafter, some favorable characteristics of the inventive arrangement of described structure and equipment are again emphasized.
– is except using blower fan, the high tower structure of application appropriateness decreases the demand (blower fan even can be made in cold weather to quit work) of auxiliary power, and warm air makes it possible to avoid warm air to be again circulated to aerial cooler in the At The Height dissipation of the rising of tower height.
The dual ventilation source of – improves availability and reliability.
– blower fan in tower relative to the location of aerial cooler:
– reduces the negative wind scorpion for cooling tower performance caused by the loss of fan static pressure head;
– protects blower fan and driving thereof to avoid suffering by wind or the wind-induced dynamic force of battle array (this is the modal cause of mechanical breakdown);
– reduces noise emission: the noise emission minimizing of air inlet side is the sound-absorbing effect had because of arrangement due to aerial cooler panel and triangle thereof, and the noise emission minimizing at air outlet slit place is the height of release owing to raising.
– is when tower structure has the diameter identical with the roundel diameter of cooling triangle disposed thereon, and it can be supported by triangle-frame---and this causes the obvious reduction of infrastructure cost.
The utility model also relates to the embodiment of any combination comprising introduced technical scheme and feature.Should also be mentioned that, the embodiment that the utility model proposed is arranged is not limited to those embodiments described herein.Therefore, this utility model is not limited to the preferred embodiment above described in detail, and other variants, combination, remodeling and development all may be included in the scope that is defined by the claims.
