Human life without water purifier, industrial production is also without water. With the development of industrial production of water purifier which brand is good, water consumption is growing, there have been many areas of water shortage, therefore reasonable and water conservation has become the development of industrial production is an important issue. Industrial water including boiler water, process water, washing water and cooling water, sewage. Which is the largest water cooling water, accounting for more than ninety percent of the industrial water consumption. Different industrial systems and different uses of the water quality requirements are different; but the cooling water used in various industrial sectors for water quality requirements are basically the same, which makes cooling water quality control in the application of technology as an access to the rapid development . In the factory, the cooling water is mainly used for condensing steam, cooling products or equipment, if the cooling effect is poor, it will affect production efficiency, product quality and product yield decline, and even cause accidents. And water, air is a commonly used cooling medium. Thermal conductivity of water and air are very poor, water purifier ranked at 0 ℃, thermal conductivity of water is 0.49 kcal / m · hr · ℃, the thermal conductivity of air is 0.021 kcal / m · hr · ℃, but water compared to air, thermal conductivity of water is about 24 times higher than air. Therefore, when the cooling effect is the same, cooling water than air cooling equipment is much smaller. Large industrial enterprises and heavy water plants are generally used water cooling. Commonly used water-cooling system can be divided into three categories, namely the DC system, closed system and an open evaporation system, the latter two cooling water is recycled, it is also known as circulating cooling water system. Cooling water system with water cooling process media system is called the cooling water system. Cooling water systems are usually two: once-through cooling water systems and circulating cooling water system. Once-through cooling water system in once-through cooling water systems, cooling water only once, after the use of water will be discharged through the heat transfer equipment, water purification agents therefore, it's a great amount of water, and drain the water temperature rise is very small , various minerals and ion content in water substantially unchanged. Purification water (finished tank) 1) The role: mixed-bed water into purified water tank, and then sent to the various water points by purifying tank. 2) Control: purification tanks are equipped with high and low level switch, control mixed bed of feed water pump. When the purified water tank at a low level, the mixed bed to the pump to work, to purified water tank; high water, mixed bed to the pump to stop working.
