Stainless steel cooling tower manufacturer price model 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 water temperature. Its cooling is the use of water and air flow to exchange heat and cold. Steam is generated, and the steam volatilizes and takes away heat to achieve evaporative heat dissipation, convection heat transfer and radiation heat transfer. It is an evaporative heat dissipation device that dissipates the waste heat generated in industry or refrigeration and air conditioning to reduce the water temperature to ensure the normal operation of the system. The device is generally It is barrel-shaped, hence the name cooling tower.
The cooling tower is a comprehensive product integrating aerodynamics, thermodynamics, fluids, chemistry, biochemistry, materials, static and dynamic structural mechanics, processing technology and other disciplines. Water quality is a function of multiple variables, and cooling is a comprehensive process of multiple factors, variables, and effects. Product Principle
There must be a certain amount of surplus energy in the cooling tower circulating water system. During operation, this energy is gathered at a certain valve, and over time this energy is lost in vain. The external turbine uses this
excess energy
The key to how to achieve motor driving efficiency of a mounted water turbine is to understand the surplus energy in the design of the cooling tower circulating water system. At the same time, the impeller design of the water turbine is also key. The composition of the surplus energy is mainly composed of the following parts
) circulation The margin value that must be considered when designing the water system
) The potential energy utilization of the heat exchange equipment
) The self-regulating ability of the turbine
) The kinetic energy conversion efficiency of the circulating water system
) The valve does not The energy consumed by the valve when it is fully opened.
) Low flow rate meets system requirements through merging and then splitting method.
Energy-saving renovation of the old cooling tower
The cooling tower and the heat exchange equipment are driven by a water pump. The external water turbine uses the return water pressure energy to convert and drive the water turbine to drive the fan. Generally, there are three cooling The towers were undergoing energy-saving renovations. The designed flow rate was too high and the actual usage was about 100%. Taking into account the changes in production demand, the energy-saving renovation method was that two towers were driven by turbines and one tower was driven by a motor for backup in summer
