How do the finned tubes be classified by application? There are many kinds of finned tubes, and new varieties are emerging. In general, finned tubes can be classified into the following categories in application: the function of finned tubes in the operation of drying equipment is to heat materials for hot air, so that the moisture in materials will evaporate, and then in the process of cyclic drying, because the air with higher temperature is close to saturation state. Therefore, the high temperature and humid air in the finned tube can no longer take away the moisture in the material, so the moisture in the material begins to stop evaporating, and continuing to operate will have adverse effects on it, which needs to be eliminated. 在一般的情况下，如果是材料的含水量较高的话，就会在很短的时间内就会造成外界热空气的较为饱和的状态，如果一般都采用的全新风进行干燥，就是指翅片管的翅片管在进行加热之后，把达到温度的热空气在送进干燥器里，同时再→另外一段排出，在隧道式烘道内，热空气的流向与物料的流量相逆流。
In general, if the moisture content of the material is high, it will cause a relatively saturated state of the hot air outside in a very short time. If the fresh air is generally used for drying, it means that the finned tube of the finned tube is heated and the hot air that reaches the temperature is fed into the dryer. At the same time another section is discharged. In the tunnel drying channel, the flow direction of hot air is countercurrent to the flow rate of material.
Another case is hot air cycle drying, because the moisture content in the material is not high, so it is not easy to saturate the hot air in a short time, but if the drying conditions need to maintain a certain evaporation temperature conditions, at this time, more use to exclude part of the hot and humid air, supplement part of the fresh air, saving. Energy consumption, reduce production costs. The replenishment of fresh air is generally 20-30%, depending on the technological requirements.
Finned tubes are classified according to processing technology.
1. series tube (sleeve tube);
2. tension winding fin tube;
3. insert tube;
4. integral rolling fin tube;
5. casting finned tube;
6. welding finned tubes, which are divided into high frequency welding finned tubes, submerged arc welding finned tubes, etc.
Classification by fin shape:
1. square, rectangular and circular finned tubes.
2. spiral finned tube;
3. corrugated finned tube;
4. saw tooth finned tube;
5. needle fin tube;
6. longitudinal fin tube;
7. integral plate fin tube (plate fin) and so on.
Finned tubes are classified according to material quality.
1.铜，Al, Cu/Al 翅片管；
1. copper, Al, Cu/Al finned tubes;
2. carbon steel, stainless steel, carbon steel / stainless steel finned tube;
3. cast iron (cast steel) finned tube, etc.
Finned tubes are classified according to their usage:
Finned tube for air conditioner;
Finned tube for air cooling;
Boiler: finned tube used for water wall, economizer and air preheater.
Finned tubes for waste heat recovery of various kilns and industrial furnaces;
Other special purpose finned tubes, etc.辛苦整理.转载请注明http://www.wxsxsjx.com
