Problems solved by technology

It only takes 4 to 5 years for the bamboo stalks of large scattered bamboos such as Moso bamboo to mature, and the maturation time for small bamboos and clustered bamboos is shorter, about 2 to 3 years. It has sustainable material sources, high surface density, and wear-resistant , bright and clean, small resistance, long-term resistance to hot water and freezing at 100°C, but there are also problems of moth-eaten, mildew and decay without anti-insect and anti-mildew treatment; for this reason, on the basis of the existing production technology of bamboo lattice filler, To improve and enhance it, bamboo lattice fillers are all made of bamboo or a small amount of other materials to improve strength, insect-proof, mildew-proof, anti-corrosion performance and service life

Embodiment 1

[0048] Preparation specification is the method for 1000*1000*40 mm bamboo grid filler, comprises the steps:

[0049] (1) Bamboo reinforcement and drying: select fresh bamboo tubes that are 5 to 6 years old, with an outer diameter range of φ60mm to 120mm and a wall thickness of 5mm to 10mm, sawed and cut into 1000mm long, and undergo rapid heat treatment with high temperature saturated steam at 140°C for 30 minutes, and then dry at high temperature. Dry at 96°C for 44 hours until the moisture content is 16%~18%, then saw it into arc-shaped bamboo slices 1 with a width of 40mm, and finally drill 3 holes at a distance of 150mm from the two ends and the middle part;

[0050] (2) Production of connected round bamboo poles 2: select fresh small-diameter round bamboos that are 5-6 years old and have an outer diameter of φ8mm-11mm, saw and cut them into 1010mm long, heat-treat with high-temperature saturated steam at 140°C for 40min, and then reheat Compress it into a uniform round ba...

Embodiment 2

[0054] Preparation specification is the method for 1200*650*40 mm bamboo grid filler, comprises the steps:

[0055] (1) Bamboo reinforcement and drying: select fresh bamboo tubes that are 5 to 6 years old, with an outer diameter range of φ80mm to 120mm and a wall thickness of 6mm to 11mm, sawed and cut into 1200mm long, and undergo rapid heat treatment with high temperature saturated steam at 180°C for 15min, and then Dry at a temperature of 100°C for 30 hours to a moisture content of 15-20%, then saw it into arc-shaped bamboo slices 1 with a width of 40mm, and finally drill 3 holes at a distance of 150mm from the two ends and in the middle;

[0056] (2) Production of connected round bamboo poles 2: select fresh small-diameter round bamboos that are 5-6 years old and have an outer diameter of φ8mm-11mm, saw and cut them into 660mm long, undergo rapid heat treatment with high-temperature saturated steam at 180°C for 10 minutes, and then pass through The round rod processing equ...

Abstract

The invention discloses a method for producing a bamboo grid packing. The method comprises the following process steps: (1) bamboo reinforcement and drying; (2) production of round connecting bamboo rods; (3) production of round isolation bamboo pipes; (4) assembling of the bamboo grid packing. The method has the advantages that (1) the strength is strong, and the environment is protected; (2) raw material resources are rich and sustainable, and dwarf bamboos, sympodial bamboos, moso bamboos and the like can be industrially utilized; (3) the bamboo grid packing is strong in strength, sustainable in material source, insect-proof, mothproof, anticorrosive and completely environment-friendly, influence on the environment is avoided, and a guarantee is provided for healthy development of an industrial cooling tower.

Description

technical field [0001] The invention relates to a method for manufacturing bamboo lattice filler, which belongs to the technical field of wood and bamboo processing and manufacturing in the wood industry. Background technique [0002] The role of the water spray filler in the industrial cooling tower is to form the hot water flowing through the tower into fine water droplets or water films as much as possible, to increase the heat exchange contact area and contact residence time of the hot water and cooling air, so as to fully carry out the heat exchange of water and air , to improve cooling efficiency, so a large water spray area and small ventilation resistance are people's pursuit of water spray fillers. The existing industrial cooling packings include: cement grid packing, glass fiber reinforced plastic water spraying packing, PVC plastic corrugated and slope watering packing, bamboo lattice (wooden lattice) watering packing. The disadvantages of cumbersome installation...
