工作原理
A counter flow closed circuit cooling tower facilitates heat exchange between two separate fluid circuits: one carrying the process fluid that needs cooling (typically water or another liquid), and the other containing an external fluid (often air). Here's how it generally works: •Process Fluid Inlet: Hot process fluid enters the cooling tower from the industrial process that needs cooling. •Heat Exchange Surfaces: The process fluid flows downward over heat exchange surfaces (typically tubes or plates), releasing heat to these surfaces. •External Air Inlet: Ambient air enters the cooling tower from the sides or bottom and flows upward through the tower. •Heat Transfer: As the process fluid flows down, it exchanges heat with the heat exchange surfaces. Simultaneously, the upward-flowing external air absorbs heat from these surfaces. •Induced Draft Fan: At the top of the tower, an induced draft fan creates a negative pressure, drawing the external air upwards through the tower. •Heat Dissipation: Heat from the process fluid is transferred to the external air through the heat exchange surfaces. The cooled process fluid exits the tower. •Closed Circuit Loop: The process fluid, now cooled, returns to the industrial process for reuse. The external air, now warmed, exits the tower. This process ensures efficient heat transfer while maintaining a closed loop for the process fluid, reducing water consumption and environmental impact compared to open cooling systems.
结构&特点
-
1. Fan:
Special axial fan with nylon or aluminum alloy blades.
-
2. Drift eliminators:
Made of corrosion-resistant PVC material, so that the water loss rate reaches one thousandth.
-
3. Heat exchanger:
The cooling coils are made of 304 stainless steel, purple copper, or dual-phase steel, and it has passed the high pressure test to ensure the strong pressure circulation of large-flow fluid.
-
4. Air intake louver:
Composed of packing and metal frame, used to block large pieces of debris in the external environment, and at the same time, the moisture in the spray sink is lost to the outside. The customer needs to clean up regularly. All the intake grilles of the equipment are removable, and they can be pulled up to the top, and the bottom end can be pulled back to remove them.
-
5. Water basin:
The water collection basin collects and stores the water used in the cooling process. It facilitates continuous circulation of water through the tower.
-
6. Water distribution system:
Uses large-flow basket-type nozzles to ensure continuous and even spraying of water on the surface of the coil.
-
7. Cold circulating fluid outlet:
The cold process fluid outlet in a closed circuit cooling tower is the point where cooled process fluid exits the tower after undergoing heat exchange.
-
8. Hot circulating fluid inlet:
It is connected by a flange made of galvanized or stainless steel, and the inlet pipes at the end of the connection are connected for cooling.
-
9. Spray pump:
Use high-performance brand water pumps with high flow, low power and low noise.
-
10. Channel steel base frame:
The channel steel base frame, made of galvanized channel steel, serves as the foundational structure of a closed circuit cooling tower, providing essential support and stability for the entire unit.
-
11. Make-up water inlet:
The make-up water inlet is responsible for supplying additional water to compensate for losses due to evaporation, drift, and bleed-off.
-
12. Drain outlet:
Used to remove excess water from the system to maintain optimal operating conditions.
