第一、玻璃鋼冷卻塔的類型特點
First, the type and characteristics of FRP cooling tower
酸霧凈化塔是集空氣動力學、熱力學、流體學、化學、生物化學、材料學、靜、動態結構力學,加工技術等多種學科為一體的綜合產物。水質為多變量的函 數,冷卻更是多因素,多變量與多效應綜合的過程。冷卻塔按水與空氣相對流動狀況不同,不同類型冷卻塔優、劣,是冷卻塔業界在學術上長期爭論不休的問題,這 種爭論有力地促進了冷卻塔的技術的發展,在爭論中各自揚長避短,使冷卻塔技術不斷完善,向節能降耗,提高效率,降低投資等目標不斷技術進步。冷卻塔熱力性 能好壞、噪聲高低、耗電大小、漂水多少是衡量冷卻塔品質優劣的關鍵,是用戶及設計師在選用冷卻塔時反復考察比較中觀注的焦點。
Acid mist purification tower is a comprehensive product integrating aerodynamics, thermodynamics, fluid science, chemistry, biochemistry, materials science, static and dynamic structural mechanics, processing technology and other disciplines. Water quality is a multi variable function, and cooling is a multi factor, multi variable and multi effect process. According to the different relative flow conditions of water and air, different types of cooling towers are superior and inferior, which is a long-standing academic debate in the cooling tower industry. This debate has effectively promoted the development of cooling tower technology. In the debate, each has its own strengths and weaknesses, so that the cooling tower technology continues to improve, to energy conservation and consumption reduction, to improve efficiency, to reduce investment and other goals. The key to evaluate the quality of cooling tower is its thermal performance, noise, power consumption and water floating. It is also the focus that users and designers repeatedly study and compare when choosing cooling tower.
一、逆流塔:
I. countercurrent Tower:
1、水在塔內填料中,水自上而下,空氣自下而上,兩者流向相反一種冷卻塔。
1. In the packing of the tower, water flows from top to bottom and air flows from bottom to top. The two flows to the opposite cooling tower.
2、逆流冷卻塔熱力性能好、分三個冷卻段:
2. The countercurrent cooling tower has good thermal performance and is divided into three cooling sections:
①布水器到填料頂這一空間,此段的水溫較高,所以仍可將熱量傳給空氣。
① from the water distributor to the filler top, the water temperature in this section is high, so the heat can still be transmitted to the air.
②填料水與空氣熱交換段。
② heat exchange section of packing water and air.
③填料至集水池空間淋水段,水在此段被冷卻稱之為“尾效”。在我國北方水溫可下降1-2℃。綜上所述,逆流塔比橫流塔在相同的情況下,填料體積小20%左右,逆流塔熱交換過程更合理冷效高。
③ the water pouring section from the filler to the sump is called "tail effect" when the water is cooled. In the north of China, the water temperature can drop 1-2 ℃. To sum up, the counterflow tower is about 20% smaller than the crossflow tower in the same case, and the heat exchange process of the counterflow tower is more reasonable and the cooling effect is higher.
3、配水系統不易堵塞、淋水填料保持清潔不易老化、濕氣回流小、防凍化冰措施更容易。多臺可組合設計,冬季以所需的水溫水量可合并單臺運行或全部停開風機。
3. The water distribution system is not easy to block, the drenching filler is clean and not easy to age, the moisture reflux is small, and the anti freezing and ice melting measures are easier. Multiple fans can be designed in combination. In winter, with the required water temperature and water volume, one fan can be combined to operate or all fans can be shut down.
4、施工安裝檢修容易、費用低,常用在空調和工業大、中型冷卻循環水中。
4. The construction, installation and maintenance are easy and the cost is low. It is commonly used in air conditioning and industrial large and medium-sized cooling circulating water.

二、橫流塔:
II. Cross flow tower:
l、水在塔內填料中,水自上而下,空氣自塔外水平流向塔內兩者流向呈垂直正交一種冷卻塔。常用在噪聲要求嚴格的居民區內,是空調界使用較多的冷卻循環塔。優點:節能、水壓低、風阻小、亦配置低速電機、無滴水噪聲和風動噪聲,填料和配水系統檢修方便。
1. Water is in the packing in the tower, water flows from top to bottom, and air flows from the outside of the tower horizontally to the inside of the tower. The two flows are perpendicular to each other. It is often used in residential areas with strict noise requirements, and it is the cooling and circulating tower that is widely used in the air conditioning industry. Advantages: energy saving, low water pressure, small wind resistance, also equipped with low-speed motor, no dripping noise and wind noise, convenient maintenance of packing and water distribution system.
2、可隨建筑形狀隨意構筑基礎多臺放置,根據所需的水溫分別啟動單臺或多臺冷卻塔。
2. Multiple foundations can be built and placed at will according to the shape of the building, and single or multiple cooling towers can be started according to the required water temperature.
3、應注意的是:框架要多40%熱交換時要有較多的填料體積,填料易老化、配水孔易堵塞、防結冰不好、濕氣回流大。橫流塔的優點正是逆流塔的缺點。
3. It should be noted that the frame with 40% more heat exchange should have more packing volume, the packing is easy to age, the water distribution hole is easy to block, the anti icing is not good, and the moisture reflux is large. The advantage of cross flow tower is the disadvantage of counter flow tower.
三、噴霧通風無填料冷卻塔:
Three, spray ventilation without packing cooling tower:
采用獨特的噴霧噴嘴安裝在冷卻塔底上部進風處,有噴霧自旋無電機送風和塔頂排風兩種方式。將熱水經噴嘴內旋片時產生內旋流形成細微霧狀化噴出,使霧狀存 在、向上噴順流亦下落逆流兩個冷卻時效。霧化均勻無中空現象,冷卻效果穩定、電能消耗低、漂水率0.01%,不用填料、造價低壽命長,符合 GB7190.1-1997國家標準。使用范圍冶金、食品、化工、高濁、高溫、防腐冷卻塔。
A unique spray nozzle is installed at the upper inlet of the cooling tower. There are two ways: spray spin, no motor supply and tower top exhaust. When the hot water passes through the inner rotating plate of the nozzle, the inner rotating manifold will be formed into a fine atomization and ejected, so that there are two cooling aging effects, i.e. the existence of fog and the downflow and countercurrent of upward spray. The atomization is uniform without hollow phenomenon, the cooling effect is stable, the electric energy consumption is low, the floating water rate is 0.01%, the packing is not used, the cost is low and the service life is long, which conforms to the national standard gb7190.1-1997. Application scope: metallurgy, food, chemical industry, high turbidity, high temperature, anti-corrosion cooling tower.

四、封閉式冷卻塔
IV. closed cooling tower
1. 封閉式冷卻塔是傳統冷卻塔的一種變形和發展。它實際上是一種蒸發式冷卻塔,冷卻器和濕式冷卻塔的組合,它是臥式的蒸發式冷卻塔,工藝流體在管內流過,空氣 在管外流過,兩者互不接觸。塔底蓄水池內的水由循環泵抽取后,送往管外均勻地噴淋下來。與工藝式流體熱水或制冷劑和管外空氣并不接觸,成為一種封閉式冷卻 塔,通過噴淋水增強傳熱傳質的效果。
1. Closed cooling tower is a kind of deformation and development of traditional cooling tower. It is actually a combination of evaporative cooling tower, cooler and wet cooling tower. It is a horizontal evaporative cooling tower. The process fluid flows through the pipe and the air flows outside the pipe. The two do not contact each other. The water in the reservoir at the bottom of the tower is pumped by the circulating pump and sent to the outside of the pipe for uniform spraying. It does not contact with process fluid hot water or refrigerant and the air outside the tube, so it becomes a closed cooling tower, which enhances the effect of heat and mass transfer by spraying water.
2.封閉式冷卻塔適用于對循環水質要求較高的各種冷卻系統,在電力、化工、鋼鐵、食品和許多工業部門有應用前景。另一方面,與空冷式熱交換器相比,蒸發式冷卻塔利用管下側水的蒸發潛熱,使空氣側傳熱傳質顯著增強,也具有明顯的優點。
2. The closed cooling tower is suitable for all kinds of cooling systems with high requirements for circulating water quality, and has application prospects in electric power, chemical industry, steel, food and many industrial sectors. On the other hand, compared with air-cooled heat exchanger, evaporative cooling tower makes use of the latent heat of evaporation of water under the tube, which makes the heat and mass transfer of air side significantly enhanced, and has obvious advantages.
