1.Overview of shell and tube heat exchanger:
Shell and tube heat exchanger is also called shell and tube heat exchanger. It is a wall heat exchanger that uses the wall of the tube bundle enclosed in the shell as the heat transfer surface. This type of heat exchanger has a simple structure, low cost, wide flow cross-section, and is easy to clean scale; but the heat transfer coefficient is low and the floor space is large. It can be made of various structural materials (mainly metal materials), can be used under high temperature and high pressure, and is the most widely used type.
2.Shell and tube heat exchanger categories:
Shell and tube heat exchangers include fixed tube plate steam-water heat exchangers, shell and tube steam-water heat exchangers with expansion joints, floating head steam-water heat exchangers, U-shaped shell and tube steam-water heat exchangers, corrugated shell and tube steam-water heat exchangers, and segmented water-water heat exchangers.
3.Features of shell and tube heat exchangers:
3.1. High efficiency and energy saving, the heat transfer coefficient of the heat exchanger is 6000-8000W/m2.0C.
3.2. Made of all stainless steel, it has a long service life of more than 20 years.
3.3. Changing laminar flow to turbulent flow improves heat exchange efficiency and reduces thermal resistance.
3.4. Fast heat exchange speed, high temperature resistance (400℃), high pressure resistance (2.5Mpa).
3.5. Compact structure, small footprint, light weight, easy installation, saving civil engineering investment.
3.6. Flexible design, complete specifications, strong practical targeting, saving money.
3.7. Wide application conditions, suitable for a large pressure, temperature range and heat exchange of various media.
3.8. Low maintenance cost, easy operation, long descaling cycle, easy cleaning.
3.9. Nano thermal film technology is used to significantly increase the heat transfer coefficient.
3.10. The application field is broad and can be widely used in thermal power, factories and mines, petrochemicals, urban centralized heating, food and medicine, energy electronics, machinery and light industry, etc.
3.11. The heat transfer tube adopts a copper tube with rolled fins on the outer surface, which has high thermal conductivity and large heat exchange area.
3.12. The guide plate guides the shell-side fluid to flow continuously in the heat exchanger in a broken line shape. The guide plate spacing can be adjusted according to the optimal flow rate. The structure is strong and can meet the shell-side fluid heat exchange with large or even super large flow and high pulsation frequency.
3.13. When the shell-side fluid is oil, it is suitable for heat exchange of low viscosity and relatively clean oil.
