Spiral threaded tube heat exchanger features:
1, spiral threaded tube heat exchanger, original u-shaped thread, small spiral gap of zui, positive and negative winding structure, steam into the tube, water into the shell, unique two-phase fluid operation mode, great change The fluid flow state has good turbulence effect and the heat transfer coefficient can reach 13600W/m2?k. Efficient heat transfer, compact structure, small footprint, and only one-fifth of the volume of conventional
Heat Exchangers.
2, spiral threaded tube heat exchanger, heat exchange tube for copper tube temperature 260 ° C, heat exchange tube for stainless steel tube temperature 400 ° C, withstand voltage 1. 6Mpa, using 1000 connections, so that the heat exchangers all participate in heat transfer The steam enters the heat exchange capillary beam and the heat exchange noise is very low, the water vapor is small, the heat loss is small, and the heat conversion rate is over 97%.
3, spiral threaded tube heat exchanger, steam side zui large volume 13 liters, a single threaded pipe only 0.1 liters, less than the national 25 liters, for non-pressure containers, to avoid the pressure vessel management, single threaded tube pressure strength At 4MPa~8MPa, and steam enters the heat exchanger capillary heat exchange tube bundle for condensation heat transfer, the decompression process is very rapid, and will not cause overpressure and unsafe hidden danger.
4. The spiral threaded tube heat exchanger has excellent heat exchange effect. In the steam-water heat exchange, the heat exchange tube is made of copper material, and there is almost no temperature difference between the condensed water and the influent water. The stainless steel has only two degrees of temperature difference, and generally does not need to install a steam trap. . The heat is completely lost in heat exchange, and the energy saving effect is extremely remarkable.
5, spiral threaded tube heat exchanger, shell flow fluid flow rate of 2. 5m / s ~ 5. 5m / s, water has a certain shear force, the tendency of fouling is low. Even if the scale is formed, the scale on the surface of the threaded pipe is threaded. The temperature change during the operation of the equipment causes the tube to expand and contract, so that the scale layer can be detached by itself, and the scale layer of the light pipe is a cylinder without any self-disengagement. Fouling cleaning: As long as the heat exchanger is removed and soaked and backwashed with an acidic solution, it is very convenient.
Spiral threaded tube heat exchanger market advantage:
1. With the shell-and-plate heat exchangers on the market, steam-water heat exchange has obvious advantages in technology, high temperature resistance, high pressure resistance, corrosion resistance of all stainless steel, high heat transfer coefficient, small volume, easy cleaning, beautiful appearance and energy saving. 10% or more.
2, technology independent, with national patents, completely domestic. The product price is basically the same as that of the double-tube heat exchanger in the market, and it has obvious advantages compared with similar foreign products.
