Abstract
Disclosed are a bamboo grid cooling filler for a cooling tower and a manufacturing method for the bamboo grid cooling filler. The bamboo grid cooling filler comprises gratings formed by arranging bamboo strips at intervals. The gratings are stacked up and down to form grids. The bamboo grid cooling filler is characterized in that the section of each bamboo strip is arc, and a through crossed drainage groove is formed in the lowest point of the arc surface of each bamboo strip; the sections of the horizontal and vertical groove bodies of each crossed drainage groove are in a V shape; the small end of the V-shaped section of each drainage groove is arranged on the outer surface of the corresponding bamboo strip; the ratio of the width of the small end of each V-shaped section to the width of the large end of the V-shaped section is 1:3.5, and the width of the small end of each V-shaped section is 1.5 mm; the horizontal and vertical groove bodies of each crossed drainage groove are both 8-12 mm long. The water drenching area is larger, and meanwhile the film heat exchange function is better, so that time for contact between steam and water is greatly prolonged; a water film shaped like a grid is formed, ventilation resistance is low, cooling efficiency is high, and the service life is prolonged.
Description
Technical field
The present invention relates to industrial cooling tower makes field with bamboo wood packing.
Background technology
The effect of Industrial cooling tower packing is for the hot water entering tower to form tiny water droplet or moisture film as far as possible, increases
Heating water and cooling air heat exchange contact area with contact the time of staying, fully to carry out aqueous vapor heat exchange, improve cooling effect
Rate, therefore big drenching area and little flowing resistance, are the pursuits to packing for the people.Existing industrial cooling filler
Have: cement grid packing, fiberglass packing, pvc plastics waveform and oblique wave packing etc..Cement grid packing is stupid because having
Weight, high labor intensive, produce install trouble, intolerant to burn into rough surface the shortcomings of, gradually eliminated by pottery.Fiberglass water drenching is filled out
Although material intensity, decay resistance, resistance to elevated temperatures are superior, because its production cost is too high, limit its popularization and application.pvc
Plastic water showering filling material is lightweight, and production is easy for installation, labour intensity is little, low production cost, surface area are big, good cooling results
Advantage, be widely used in each industrial cooling system.But there is low intensity in plastic water showering filling, intolerant to burn into intolerant to height
Warm, easily aging service life is shorter the shortcomings of become fragile, and running 3-5 just needs to change, and secondly, in operation, plastic crushing is brought into and is
System, can block circulation, and therefore Maintenance and Repair workload is big, changes frequently.
Chinese patent patent cn20191768 is open to combine packing although filling out with respect to plastics water drenching using bamboo sheet
Material, bamboo wood has happiness water and is not afraid of freeze thawing, and toughness is strong, and the bright and clean resistance in upper surface is little, and has one layer of hard conservation of nature
Layer, the features such as can repelling the corrupting influence, overcomes plastic water showering filling low intensity, lacks intolerant to burn into non-refractory, easily aging become fragile etc.
Point.And bamboo chip is cambered surface, drenching area can be produced to greatest extent, but the film effect that its drainage slot structure produces is weaker,
It is further improved.
Content of the invention
