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 bamboo wood packing and make field.
Background technology
The effect of Industrial cooling tower packing is the hot water entering tower to form tiny water droplet or moisture film as far as possible, increase hot water and cooling-air heat exchange contact area and contact the time of staying, fully to carry out aqueous vapor heat exchange, improve cooling effectiveness, therefore large drenching area and little flowing resistance are the pursuits of people to packing.Existing industrial cooling filler has: cement grid packing, fiberglass packing, PVC plastic waveform and oblique wave packing etc.Cement grid packing because of have heaviness, labour intensity large, produce shortcomings such as installing trouble, not corrosion-resistant, rough surface, eliminated by pottery gradually.Although fiberglass packing intensity, decay resistance, resistance to elevated temperatures are superior, because its production cost is too high, limit it and apply.PVC plastic packing material is lightweight, produce easy for installation, labour intensity is little, production cost is low, surface area is large, the advantage of good cooling results, be widely used in each industrial cooling system.But plastic water showering filling exists, and intensity is low, not corrosion-resistant, non-refractory, the easily aging shortcoming such as to become fragile, and service life is shorter, and running 3-5 just needs to change, secondly, in operation, plastic crushing brings system into, can block circulation, therefore Maintenance and Repair workload is large, changes frequent.
Chinese patent patent CN20191768 openly adopts bamboo sheet to combine packing; although relative to plastic water showering filling; bamboo wood has happiness water and is not afraid of freeze thawing; toughness is strong; and the bright and clean resistance of upper surface is little; and with one deck hard natural protective layer, the feature such as can to repel the corrupting influence, overcomes that plastic water showering filling intensity is low, not corrosion-resistant, non-refractory, the easily aging shortcoming such as to become fragile.And bamboo chip is cambered surface, drenching area can be produced to greatest extent, but the film effect that its drainage trough structure produces is more weak, is further improved.
