Cooling Tower manufacturers in the future development
Cooling Tower industry has entered an unprecedented attention. In the State Council announced the "second five energy-saving comprehensive work program," stressed: to study the determination of high energy-consuming products and end-use energy products, the level of energy efficiency, energy efficiency standards in the growth of the leader, Energy efficiency standards and energy efficiency projects, promote the use of energy-saving products to promote technological progress, accelerate the pace of upgrading the standard.
The waste heat of the Cooling Tower carrying the cooling water inside the tower, through the heat exchange of air, so that heat is transferred to the air and separated into the atmosphere, which is the production of energy-saving equipment is essential.
Cooling Tower design wet bulb temperature of 28 ℃, under normal circumstances, according to the wet bulb temperature of 27 ℃ design of the Cooling Tower can be distinguished in the ventilation, no other special environment, the normal use of micro-climate in the northern region, but after years of operating Cooling Tower Results The information collected through the feedback shows that in some southern areas of hot and humid climatic conditions or some poorly ventilated, easy to form high temperature environment microclimate buildings, according to wet bulb 28 ℃ design of the Cooling Tower to show its excellent cooling effect and Extraordinary ability to adapt, the target designer, installers and users to bring peace of mind confidence.
Cooling Tower cooling effect depends mainly on the size of the air flow and heat transfer area, and the size of the air flow depends on the size of the Cooling Tower motor power and Cooling Tower fan blade angle size; we all know that the Cooling Tower is a mechanical refrigeration , Said the white is driven by the motor to drive the fan to produce enough air volume, like the summer with the same fan, the fan of the stalls the greater the amount of air naturally the greater, but if the surrounding wet bulb temperature is too high, the greater the air flow , But the cooling effect is worse. Heat transfer area is actually the size of the Cooling Tower packing area, the Cooling Tower fan is the flow of air, and the main role of the filler is to prevent the circulating water when the flow rate, you can let the circulating water and flow of air can be connected with the cold Air to cool the hot water, the greater the heat transfer area, the more cold air and circulating water heat exchange, the greater the heat taken away; so the Cooling Tower cooling effect is the most important is the size of the heat transfer area ; The size of the heat transfer area is mainly composed of two parts, one is the shape of the Cooling Tower packing, but the height of the Cooling Tower packing.
In summary, the Cooling Tower cooling is not the main reason, (excluding the selection is too small) is basically these two points, so if you find the Cooling Tower cooling effect is not good, first of all from these two considerations; Check the filler is blocked, the second can be appropriate to adjust the Cooling Tower fan angle, but it is best to be adjusted in the professional, or once the fan is not balanced, different heart, then directly damage the Cooling Tower motor.
FRP Cooling Tower materials are generally carbon steel, stainless steel and copper-based, in which carbon steel tube plate as a Cooling Tower used, the tube plate and tube welds often corrosion leakage, spill into the cooling water system Will cause pollution of the environment and waste materials.
Cooling Tower in the production, the tube plate and the tube of the general use of manual arc welding, weld shape there are different degrees of defects, such as depression, pores, slag, etc., the distribution of weld stress is not uniform. When used, the tube sheet part is in contact with the industrial cooling water, and the impurities, salts, gases and microorganisms in the industrial cooling water constitute the corrosion of the tube sheet and the weld. Studies have shown that industrial water, whether fresh or seawater, will have a variety of ions and dissolved oxygen, which chloride ion and oxygen concentration changes, the corrosion of metal plays an important role in the shape. In addition, the complexity of the metal structure will also affect the corrosion form.
In view of the problem of Cooling Tower corrosion, the traditional method to repair welding mainly, but make welding tube tube internal internal stress, it is difficult to eliminate, may cause the Cooling Tower tube plate weld again leakage. Western countries are more use of polymer composite materials to protect the method.
