Cooling tower of the cooling process is mainly conducted on thermal filler panel (packing heat accounts for more than 85% of the whole temperature drop in the cross-flow tower), packing on the surface of the water film, slow down and the inner water membrane humidity 100% high enthalpy wet air, the water molecules from high enthalpy region ran to low enthalpy value into the tower in the fresh air, use tower air enthalpy value increase. As the concentration of water molecules decreases, the water molecules in the circulating hot water evaporate from liquid to gas, taking away the latent steam heat. According to the above principle, the quality of packing is the key to refrigeration effect.
The square cross flow series cooling tower core material is made of high quality modified PVC and polyvinyl chloride sheet material with vacuum blister molding, because of the use of trapezoidal wave packing, the heat dissipation area growth coefficient is large, the water flow on the surface of the distribution performance is good, water and air flow through the surface of the disturbance and so on. The air inlet has a honeycomb wind distribution device, so that the tower will not produce uneven wind distribution phenomenon due to uneven packing distance, uniform wind load so that the tower's cooling packing area is effectively used. Because of the three-dimensional characteristics of the honeycomb inlet, most of the sunlight can not penetrate the packing surface of the tower body, so it is difficult to grow moss on the packing surface. The packing is not easy to deform, high temperature resistance (temperature resistance 50℃ ~ 68℃), anti-aging, and good flame retardant performance (flame retardant oxygen index index is 33.3%), small wind resistance coefficient. The technical principle of inertial impact separation method is adopted at the end of the water pouring filler. The water collector with the filler can reduce the loss of floating water to 1/100000 level.
Packing for hanging installation, is the first in the cooling tower industry, effectively overcome many shortcomings of the commonly used binder packing.
Feature 1: the packing adopts inclined hanging type installation, the bottom of the packing is suspended, will not deposit debris, smooth water flow, and can prevent the growth of algae and bacteria.
Feature two: no glue bonding, no deformation, no embrittlement, effectively solve the problem of packing scaling.
The old installation method adopts the glue bonding method, and the packing is stacked in the cooling tower. When using, the bonding point of the packing is easy to scale, and the scaling is accumulated over a long period of time. After serious bending and deformation, it collapses, thus affecting the cooling performance.
Feature three: increase the effective air inlet area. More steel support is required at the bottom of the binder packing. The steel support reduces the effective air inlet area of the packing, and the packing suspension installation does not require the support steel frame.
Feature four: packing installation, transportation, maintenance work is simple and convenient.
1. Before replacing the packing of the cooling tower, protect, isolate and hang out the other equipment on the site; Laying construction material cloth on the waterproof layer of the floor to prevent damage;
2. Remove the packing of the cooling tower and turn off the power of the motor; Remove the cooling tower packing part of the tension; Remove the old filler; Garbage cleaning in the tower; Clean up the scene;
3, cooling tower packing bonding, because the packing bonding amount is large, to ensure that the packing has enough space to place during the curing of the binder, in the bonding process, the packing contact point is on the same level, to ensure that the packing contact point is uniform and compact in the process of pressing;
4. Clean up the dust and garbage on the internal parts of the cooling tower to ensure cleanness. Stacking the packing into the cooling tower is forbidden to trample on and vigorously extruding the packing in the process.
5. When replacing the packing of the cooling tower, we should pay attention to the upper and lower direction of the assembly block, and the top surface of each layer should be laid flat, and the layers should be clear and clean, and no debris should be blocked.
6, installation, maintenance and other work need to work on the filler, must be spread on the plate, is strictly prohibited directly trampling.
7. In the process of construction, assembly and installation, it is strictly prohibited to weld above the packing of the cooling tower. When necessary, fire prevention measures should be taken. After the installation, take out all the construction tools and auxiliary installation facilities in the cooling tower to hand over the construction completion plan and wait for acceptance. The filling replacement step of the cooling tower is completed.
Packing is the most important part of cooling tower, its efficiency is high or low, depends on the cooling water and air in the packing full contact degree.
As we all know, the surface of the packing because of the evaporation of water in the circulating water, the concentration of inorganic substances increases and crystallization precipitation, scaling on the surface of the packing and the tower, the inner wall of the pipe; Many manufacturers of packing is to rely on, adhesive and bracket of live in use in a "vicious circle", also is the heavier weight after fouling, packing in the case of overload, add water, "bending deformation occurs, and the deformation after packing positive impact, the water impact, in turn, make the deformation is more serious, this is a kind of irreversible" vicious circle ", start the cycle, packing soon make adhesive contact with tensile fracture, collapsed, causing cooling tower cooling capacity is reduced, the main equipment heat damage, this is the reason why cooling tower packing: why do you want to change.
