Description
The utility model belongs to the crossing current direct contact water and drenches cooling tower field, particularly industrial circulating cooling water cooling tower field.
At present, the version of circulating water cooling tower mainly is divided into two big classes, and tower and countercurrent tower promptly flow over.This two classes tower respectively has two kinds of forms again according to the difference of its filling-material structure, i.e. drop packed tower and film packed tower.Wherein, crossing current drop packed tower (also claim crossing current diaphragm type cooling tower, be called for short the drop tower) and crossing current film packed tower (also claim crossing current drip cooling tower, be called for short the film tower) are used comparatively extensive.The structure difference of these two kinds of crossing current towers, and differ greatly.For example, unidimensional blower fan, the packed height of film tower is short 3～4 meters than the drop tower; The footpath of filler is dark: the film tower should not surpass 3 meters, and 5.5 meters of drop Ta Keda; The contraction inclination angle that filler is installed: the film filler is 5 °～6 °, and the drop filler is 9 °～11 °; The volume matter coefficient that looses: the film filler is 8000～12000, and the drop filler only is 4000～6000.Just because of this, when design is selected for use, always be that two kinds of fillers use separately separately.Yet these two kinds of fillers have his own strong points in practicality, and shortage is also respectively arranged.For example, the advantage of drop tower is: amount of filler is few, and installation volume is big, and windage is little, is difficult for stopping up and fouling, and shortcoming is that the boundary layer filler damages easily, influences the air distribution even water distribution of full tower, and it is bad to receive the water effect, and cooling capacity is poor; The advantage of film tower is: floor space is little, the filler long service life, and the volume matter coefficient height that looses, thermodynamic property is good, and filler can bear bigger spray density etc., and shortcoming is that amount of filler is big, and expense is higher, easily blocks, fouling, to the water quality requirement height.
The seventies, China introduced 13 cover large chemical fertilizer devices from industrially developed country, and industrial circulating cooling water cooling tower technology is also introduced thereupon, wherein with U.S. Ma Li company-600 type cooling tower better performances.Through to the improvement of Ma Li company-600 type cooling tower technology, be that the large-scale crossing current drip cooling tower of sign is in industrial circulating water field extensive uses gradually such as China's oil, chemical industry, chemical fibres with modification P.V.CM shape filler.In actual applications, since composition of tower shell material and structural difference (the cooling tower tower body of U.S. Ma Li company is mainly timber structure, venetian blind type; And the cooling tower of China mainly is structures such as cement frame, and shutter also is that cement plate is made), therefore, three big problems have appearred in the crossing current drip cooling tower that China builds in real tower is used: (1) boundary layer M shape plate drop filler well damage; (2) receipts water effect is bad, and the windage loss amount is excessive; (3) cooling capacity of tower does not reach the level of the former tower of U.S. Ma Li company.
For overcoming the deficiencies in the prior art, raise the length of the above-mentioned two kinds of structures of crossflow cooling tower, keep away the weak point of two kinds of structures, improve the cooling effectiveness of tower, save growing a large amount of water for industrial use, save maintenance cost of cooling tower or the like, the crossflow cooling tower that the utility model provides a kind of film, drop filler to load in mixture.
The crossflow cooling tower that film of the present utility model, drop filler load in mixture is to improve to form on the basis of existing crossing current drip cooling tower, it is characterized in that, it is that film filler and drop filler are mixed in the crossflow cooling tower, its boundary layer is the film filler, nexine is the drop filler, sees accompanying drawing 4.
Cooling tower of the present utility model, another feature are that the film filler that boundary layer is installed is overall plastic framework film filling block; The drop filler that its nexine is installed is a M shape plate drop filler.See accompanying drawing 3 and accompanying drawing 1.
In cooling tower of the present utility model, the footpath that the film filler of its boundary layer is installed is 200～2000mm deeply, and the sheet spacing is 10～100mm.
The utility model has carried out above-mentioned improvement to the crossing current drip cooling tower of prior art (particularly domestic prior art), reason is: the crossing current drip cooling tower of at present homemade concrete frame structure is that cement is board-like because of shutter, lack energy-dissipating structure, cause the boundary layer water flow impact pressure of tower excessive, boundary layer water is through constantly compiling, spray density is considerably beyond design load, the M shape filler of former boundary layer is unable to bear the impact of the excessive water curtain of boundary layer, so install and use promptly pounded behind the some months by current disconnected, cause the very fast whole damages of M shape filler of boundary layer 800mm width and form directly let out and under water curtain.Water curtain has been sealed the air intake shutter, has increased the air intake resistance, has reduced intake, makes the air distribution water distribution of cooling tower seriously irregular, causes the fan operation imbalance, and the vertical direction amplitude of oscillation is excessive, and fan blade often damages, and has influenced the cooling effect of cooling tower.Be thoroughly to solve the badly damaged problem of drop tower boundary layer M shape filler, the utility model adopts overall plastic tank bracket film filling block to replace the drop filler of former boundary layer, has realized loading in mixture of in cooling tower film and drop filler.
Damaged condition about boundary layer M shape plate drop filler in the crossing current drip cooling tower is seen accompanying drawing 2.
The film filler is different with the structure of drop filler, and mounting means is also different, and both can not use traditional viewpoint in same cooling tower, and the utility model then is the weak point that will utilize the length benefit drop filler of film filler, to solve the prior art existing problems.The employed film filler of the utility model---overall plastic framework film filling block, because of it is equipped with overall plastic framework, thus its bulk strength height, the impact that can bear the boundary layer current; Because of being the film filler, current can be led down along packing sheet layer by layer again, and the speed that falls is under water slowed down greatly; Because the sheet spacing of 10～100mm is arranged between the film packing sheet, so just original whole water curtain is torn, formed a large amount of minitype channels, the condition of having created in the tower that enters for wind significantly reduces the windage of cooling tower; In addition, because the unit volume cooling capacity of film filler is bigger approximately 1 times than drop filler, so the film filler of boundary layer also has good cooling capacity.The boundary layer of cooling tower is changed into by the drop filler after the film filler, and the filler of full tower can be brought up to 10～15 years by original 5～6 years service life.
In cooling tower of the present utility model, difunctional water collection device also is installed at the internal layer of this cooling tower (being drop packing layer the inside).This difunctional water collection device is preferably made with modification P.V.C material.This modification P.V.C water collection device has difunctional, promptly refers on the structure of water collection device: one, and it has a sinusoidal waveform; Its two, in its sinusoidal waveform, also have little sinusoidal waveform.Like this, just make the receipts water effect of water collection device very good, make the windage loss rate of cooling water be reduced to 0.001%, met and exceeded advanced international standard (0.003%).
In addition, also can increase the thin film packing layer again in the inside of cooling tower of the present utility model, promptly crossflow cooling tower load in mixture the structure that loads in mixture that structure is film filler, drop filler, three layers of filler of film filler, also can receive effect preferably.
In cooling tower of the present utility model, at the boundary layer of cooling tower distribution reservoir the water nozzle that the film filler with boundary layer is complementary must be installed, the inside of cooling tower distribution reservoir must be equipped with the water nozzle that the drop filler with nexine is complementary, to adjust the spray density of boundary layer and nexine, satisfy the actual needs of production operation.
The boundary layer of the crossing current drip cooling tower of prior art is replaced with the film filler, and according to after above-mentioned all the other specification requirements of all transformation installations, not only thoroughly solved the shortcoming of former crossing current drip cooling tower, and bring above-mentioned plurality of advantages, finally realize the air distribution even water distribution of full tower, improved the ability 20～40% of cooling tower.
