The heat exchange device is the main part of the liquid oxygen air ambient vaporizer, and the small finned tubes can absorb the heat in the atmosphere to obtain greater heat. Air-temperature vaporizer The gasifier device with huge equipment and high cost is a good helper to help enterprises save energy and increase work efficiency. The following is a brief description of the finned tube of the heat exchange device of the air ambient vaporizer.
The finned tube has an intermediate tube with radial fins outside the tube. The liquid flows in the tube, and the fins absorb the heat from the external environment and transfer it to the liquid in the tube to realize the heat absorption and gasification of the liquid. At present, the air-temperature vaporizer produced by the manufacturer Anti-embroidered aluminum alloy finned tubes are mostly used in the heat exchange device, which is determined to be that the partial wall temperature is uneven and the overall heat exchange performance is not fully utilized.
Using the finned tube with built-in liquid-absorbing core and spiral guide belt, the heat transfer coefficient of the finned tube is increased, which is more than 5 times higher than that of the finned tube without this technology!
a. The built-in liquid-absorbing core has more stainless steel belts, which are wound into a cylindrical shape and then cling to the air wall of the finned tube to condense high-temperature boiling gas and continuously provide heat.
b. The built-in spiral guide will change the flow direction of the liquid. Without the built-in spiral guide belt, the liquid flows vertically, but with the built-in spiral guide belt, the liquid flow direction is spiral upward, which increases the liquid flow rate , prolong the contact time between the liquid and the finned tube, so that the separation time of the liquid between the liquid-absorbing core and the spiral guide belt is long, which is conducive to the formation of airflow and increases the temperature of the liquid surface to boil.
The application of these two technologies, the built-in liquid-absorbing core and the spiral guide belt, can significantly change the uniformity of the temperature on the inner wall of the finned tube, increase the heat exchange effect of the ambient air heated vaporizer, and ensure the safety of the LPG vaporizer and LNG vaporizer. use.
