Cooling tower fillers

The filler material in the cooling tower is: Flame-retardant PVC is commonly known as PVC. The cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and discharge it into the atmosphere to reduce the temperature of the water. The cold tower uses water and air to make contact with the air and then exchanges heat and cold to produce steam. The steam evaporates. Take away heat to reach the principle of evaporation heat dissipation, convection heat transfer and radiation heat transfer to disperse the waste heat generated in industrial or cooling and air conditioning to reduce the water temperature evaporation heat sink to ensure the normal operation of the system, the device is generally barrel-shaped, so Called the cooling tower.



The cooling tower is an integrated product of aerodynamics, thermodynamics, fluidics, chemistry, biochemistry, materials science, static and dynamic structural mechanics, processing technology and many other disciplines. Water quality is a multivariable function, and cooling is a multi-factor, multi-variable and multi-effects synthesis process.

1. There must be some surplus energy (20%-25%) in the cooling tower circulating water system, and these energy will be accumulated in a certain valve at the time of operation, and these energy will be lost for a long time. External turbines use these "excess energy" to convert to high-efficiency mechanical energy, thereby replacing the cooling tower fan motor by 100% to save power.

2. The key to how the external turbine can achieve the motor drive efficiency is to understand the excess energy in the design of the cooling tower's circulating water system. The impeller design of the turbine is also critical. The composition of surplus energy is mainly composed of the following six parts:

1) The margin value that must be considered when designing the circulating water system;

2) Potential energy utilization of heat exchange equipment;

3) Turbine's own adjustment ability;

4) kinetic energy conversion efficiency of the circulating water system;

5) The energy consumed by the valve when the valve is not in place.

6) Low flow meets the system requirements by combining the re-shunt methods.


3. Cooling tower old tower energy-saving reform

Between the cooling tower and the heat exchange equipment, the water pump is used to circulate and drive. The external turbine uses the backwater pressure energy to convert and drive the turbine to work to drive the fan. Generally, three cooling towers are used to make energy-saving transformation. The actual flow rate during the design is larger than 60. Around %, taking into account changes in production requirements, the energy-saving retrofit method is that the two towers are driven by a turbine, and one tower is used as a motor drive during summer time.

4. Cooling tower new tower design

The work of the external turbine is focused on the return pressure or return flow to meet the turbine's ability to drive the fan to function, and the energy conservation - how much return flow or pressure conversion = how many fan speeds. The speed of the external turbine is increased or decreased according to the increase or decrease of the system flow rate. Three external turbine cooling towers and three towers of the turbine outlet pipe are connected through the system. The bypass valve is used to adjust the flow and facilitate maintenance.
