Cooling Tower in the environment-friendly economic society occupies an important position
Industrial production or refrigeration process generated waste heat, generally use cooling water to guide away. The effect of the Cooling Tower is to carry the waste heat of the cooling water in the tower with the air heat exchange, so that waste heat to the air and into the atmosphere. For example: the thermal power plant, the boiler will be heated to high temperature and high pressure steam, to promote the steam turbine to make the generator power generation, the steam turbine after the work of the waste steam discharged into the condenser, with the cooling water for heat exchange condensate into water, Back to the boiler recycling. The waste heat in this process is passed to the cooling water, so that the water temperature increases, with waste heat of the cooling water, the Cooling Tower will be heat transfer to the air, from the air duct into the atmosphere. Cooling Tower, cooling system, refrigeration series, injection, tanning, foaming, power generation, steam turbine, aluminum processing, air compressor, industrial water cooling and other fields, the most used for air conditioning cooling, freezing, Plastic chemical industry.
What is needed in industrial production is the Cooling Tower to cool the various machinery and equipment, and it is necessary to use a better quality Cooling Tower for this kind of work. Only in this way can it meet the needs of the industrial production The The new type of closed Cooling Tower in the use of the process than the average Cooling Tower more energy-efficient, which for many industrial manufacturers are very important, after all, now for the energy management is very strict, the price of various energy Continuous improvement, the company wants to earn more benefits on the need to do a good job of energy conservation, and the need to use the Cooling Tower to cool the work.
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.
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.
