Oblique cross packing
Oblique cross filler has good cooling effect, ventilation resistance is small, strong hydrophilic, large contact area, etc.Oblique cross filler used material and the screw assembly in two forms, inclination Angle of 60 degrees commonly, is mainly used for circular cooling tower.Suitable for medium and small cooling tower, not easy jam.
Characteristics: 1. The chemical stability, acid and alkali resistant and corrosion of organic solvent
The hydrophilic of products, good film-forming, easy packing heat conduction.
To adapt to the temperature of 65℃- 35℃below zero.
Oxygen index of≥31
Oblique cross filler used ring and screw assemble two kinds of shape
Specification: 50*25*60degree, width: 125*400mm, thickness : 0.35-0.6+/-0.05mm
Temperature: PVC: 20 degree centigrade below zero and 70 degree centigrade
PP: 20 degree centigrade below zero and 100 degree centigrade.
Oblique cross packing staggered packing with advanced technology, reasonable design, the data is reliable, durable, through experiment and production show that cooling effect is good, the ventilation resistance is small, strong hydrophilic, large contact area, etc.
FRP cooling tower packing is an important part of the cooling tower, are key components in the cooling tower heat, and cold effect directly related to its quality and effect to a great extent, decides the cooling capacity of cooling tower, according to the survey, stuffing the cooling to the entire 60% ~ 70% of cooling tower. It is generally made from PVC corrugated plate of uneven, hydrophilic can good, ensure the water in the water film is formed on the packing and water droplets, rather than water, enhance moisture exchange area, extend the water-gas shift time, guarantee the cooling effect.
Glass fiber reinforced plastic cooling tower packing into the S wave of glass fiber reinforced plastic packing, oblique cross glass fiber reinforced plastic packing, glass fiber reinforced plastic packing, terraced trapezoidal oblique wave point wave cooling tower packing, hexagonal honeycomb glass fiber reinforced plastic packing, differential type sine-wave FRP cooling tower packing, two-way wave of glass fiber reinforced plastic packing, obliquely wave FRP cooling tower packing of this a few kinds big.Hexagonal honeycomb wet cooling tower packing by polyvinyl chloride, polypropylene film, the heat moulding honeycomb was FRP cooling tower packing.Presence of twist glass cloth as reinforcing filler with glass fiber reinforced plastic packing.The glass fiber reinforced plastic cooling tower packing is suitable for water supply and drainage treatment of precipitation process, has wide applicable scope, the precipitation effect better, cover an area of an area small, etc.
Should be according to the type of cooling tower, water quality of circulating cooling water, cooling mission; Design operation conditions, such as choosing good stiffness, corrosion resistance, anti-aging, flame retardant performance of packing.
Counterblow cooling tower appropriate USES diaphragm or intravenous drip diaphragm; Cross flow cooling tower appropriate diaphragm of diaphragm, a bit, a little packing after comparison with the tower body height, etc.
Should choose according to feed water temperature t1 flame retardant (30 ~ 40 oxygen index), heat resistance performance of different packing:
T1 45℃or less, appropriate choice of PVC;T1 55℃or less, appropriate choice of modified polyvinyl chloride (PVC);T1 60℃or less, appropriate choice of polyester FRP.
Cold area, packing material should be the lowest monthly average temperature according to region, choose corresponding hardy levels of filler, the lowest monthly average temperature lower than a year of 8℃area should choose hardy type packing.
When the cooling water of suspended matter less than 20 mg/L, appropriate USES thin film packing. When the cooling water of suspended matter is more than 50 mg/L, appropriate USES a trickle, or drip film packing.
Thermal characteristics and resistance characteristics of the packing should be combined with a comprehensive evaluation of fan performance choice under the condition of same design cooling capacity at most. For thin film packing, when the same type but different high piece and piece combination, should carry on the contrast, when the design of water temperature difference is bigger, should choose high highly active.
When the filler piece of simply supported on the support trabecular directly, support Liang Yi USES the width is small, the structure of the ventilation resistance is small, with filler piece of simply supported beam in the distance should be the optimal match the size. When use support type, board, plate simply supported design span and support beam span should be consistent, grating corrosion resistance should be adapted to the packing.
