Floating coil heat exchanger 1 Overview of selected floating coil radiator cantilevered floating coil, the steam heating hot water in the process, plus or minus the coil so that water coil surrounding the destruction of the layer of convective heat transfer. Greatly improving the heat transfer capacity, heat transfer coefficient K≥3000W / m ℃, while the role of water due to the erosion of the tube can be free-floating boom, swelling shrink freely, and thus easy to furring, if the long-term use, the accumulation of a small amount of scale by the expansion of the tube, it will be automatically de-scale, long-term use of heat capacity and therefore does not fall to good effect. 2 applications floating coil radiator can be widely used in industrial and civil construction, such as heating, air conditioning, hot water supply systems in chemical, oil refining, shipbuilding and other factories and high-rise hotels, restaurants, office buildings, schools research buildings, Yiyuan outpatient ward building The boiler room, heat station house, air conditioning room to do heat transfer equipment. 3 equipment components floating coil heat exchanger consists of upper and lower cover, the outer cylinder, the steam inlet pipe, condensed water outlet pipe and floating coil bundle components. Wherein the top and bottom cover, the outer cylinder design made of high quality carbon steel, floating coil bundle is made of copper after repeated molding. Steam from the steam inlet pipe into the parallel floating coil after coil condensation heat in the water pipe enters Condensate export, condensate water outlet pipe of the lower part there Condensate device, water is introduced from the inlet provided on the lower end cap, the fold After the flow into the cylinder, made from the bottom, it is heated by the outlet pipe located in the upper end of the cover flow. [1] 4 structural features 1, the heat exchanger housing has two kinds of ordinary steel and stainless steel plate, heat transfer tubes are copper. 2, the heat exchanger tube design pressure steam type 0.1-0.9MPa, water - water-≤1.6MPa; housing respectively with 0.6MPa, 1.0MPa, 1.6MPa three sizes, to pay attention to the selection of equipment and equipment heat performance to match. 3, due to the high heat transfer efficiency of the heat exchanger, the temperature regulator must be installed (ie thermostat) in the heat exchanger steam inlet piping to control the flow of steam and hot water temperature. 4, heat transport and installation, cranes and other lifting equipment must be used to prevent rolling, heat exchanger should be fixed with the base firmly to prevent vibration during operation, should stay out of the heat exchanger around the maintenance position. 5 floating coil heat exchanger Features (1) using the new structure floating coil bundle, improved heat transfer capacity, while automatic descaling capacity increase; (2) the bundle can join unions, to reduce the weld repair and more convenient; compact (3) structure, small, small footprint. 6 Cautions 1. floating coil heat exchanger must be checked before use clip into bolts are loose, if loose should be pressed. And two parallel clamping plates. 2. Equipment operating pressures and temperatures must be below nameplate design pressure and design temperature. 3. Equipment inauguration strict accordance with the standard operation, slowly open the steam inlet valve, pressure shocks or sudden changes in temperature are too easily lead to equipment damage. 4. equipment import and export pipelines should be set high automatic exhaust valve, the non-condensable gas inside the equipment all ruled out, otherwise it will seriously affect the efficiency of heat exchanger, and may damage the device. 5. Run the medium at high temperature or dangerous media, anti-spray equipment should be protected to avoid media leaks cause personal injury. 7 Technical features floating coil heat exchanger technology features: 1, heat transfer enhancement spiral copper coil cantilever fixed structure, when the hot medium quality (saturated steam or hot water) flowing through the tube, the coil produce high-speed reciprocating motion, Forced heat transfer tubes surrounding water to form a disturbance, thereby greatly increasing the heat transfer film coefficient a0, reduce fluid resistance tube wall 1 / a0, increasing the overall heat transfer coefficient K. 2, automatic cleaning equipment operation due to high-speed floating coil, apply the scale is hardly deposited on the outer wall of the tube; and because the coil temperature changes arising from stretching phenomenon, even if the tube wall to form a small amount of scale will automatically fall off (available on a regular basis by the outfall discharge tank), lifting the traditional tedious cleaning process, therefore, the heat exchanger can maintain long-term best running. 3, accurate temperature control of the device for high precision "intelligence temperature controller" can be continuously and automatically detect water temperature, and command control valve regulating steam (or hot water) to enter in the coil volume, therefore, even if the load fluctuation, water temperature still remaining within the scope of the set value ± 2 ℃. 4, to reduce the area of ??the device structure is compact, covers an area of ??about 10% of the same features and tube heat exchangers, not only reduces the cost, efficient use of space, but also easy to transport and lifting.
