Tube-in-tube cooler, also known as shell-and-tube cooler, consists of the tube side and the shell side. The liquid flowing inside the tubes is the tube side, while the liquid flowing outside the tubes is the shell side. The wall of the tube bundle serves as the heat transfer surface. When the temperature difference between the tube bundle and the shell exceeds 50°C, appropriate temperature compensation measures are taken to eliminate or reduce thermal stress. Typically, it is water-cooled and holds a dominant position.
1. Tube-in-tube cooler employs bare tubes (without finned surfaces) for heat transfer, featuring high surface-to-membrane heat transfer coefficient and strong anti-pollution capability.
2. The tube of the tube-type cooler is made of purple copper, processed into finned heat exchangers, featuring a compact size and large heat exchange area.
3. Spiral-shaped baffles in the tube bundle cooler ensure the cooled liquid rolls uniformly in a spiral motion, overcoming the efficiency limitations of the baffles in a cross-flow design.
4. The tubular cooler employs胀管式封口, overcoming the adverse changes caused by material undergoing high-temperature welding.
5. Tube-and-shell coolers feature excellent structural performance, stable sealing, high heat transfer efficiency, compact structure, and minimal floor space.
Manual Process: After the water filter is connected to the pipeline system, water enters from the lower inlet into the filter. As impurities pass through the core, those larger in volume than the core holes are intercepted on the core surface. When they accumulate to a certain amount, it causes a certain pressure difference between the inlet and outlet. (The pressure difference varies with different filter precision diameters, usually around 0.15Mpa). Manually open the drain valve, initiate the draining process. Turn the handle; either clockwise or counterclockwise rotation is acceptable. Rotate one step every 10 to 30 seconds, fix the handle at each indentation, and the water reverses to rinse away impurities and debris attached to the inner wall of the core. Continue until one complete rotation is achieved, close the drain valve, and manual draining is complete.

1. Differential Pressure Backflushing: When impurities accumulate to a certain quantity, utilize the differential pressure signal between the cooling water inlet and outlet pipes for backflushing and draining. This is achieved by connecting the electrical contact pressure gauge to control the signal, which in turn opens the electric drain valve. The electric reducer operates at a speed of 3-6 rotations per minute, reversing the flow of water to rinse impurities adhering to the inner wall surface of the mesh core. The rinsed impurities are then discharged into the cooling water outlet pipe via the drain pipeline and valve. The entire cleaning and draining process takes approximately 5-10 minutes. In cases where large debris prevents the filter mesh from operating properly, the electric unit should reverse its direction to flush away the debris.
2. Users can set the timing of effluent discharge if needed.0-99 hoursThe internal cleaning and drainage time is set to 12 hours, typically, with adjustments made according to the power plant's water quality. The set time activates the electric reducer for reverse operation to open the drainage valve, followed by reverse flushing and drainage.
