The energy of cooling tower energy-saving transformation mainly comes from the surplus flow and surplus lift of the water pump in the system, so the success of the transformation is naturally inseparable from this. If the water pump of cooling tower circulating water system has no surplus flow and surplus lift (I .e. no surplus pressure), water turbine cannot be used for energy-saving transformation, but this kind of situation is still extremely rare in actual work. Generally, cavitation is taken into account in the design of water pump system, fouling and other reasons will reduce efficiency, so there is a surplus head to ensure long-term normal operation, this consideration is beyond reproach, from this point of view, the general cooling tower can be completely modified.
How to operate it? I believe this problem troubles many people. In fact, the energy-saving transformation of cooling tower is far from as complicated as we imagined. The transformation of cooling tower is to use water turbine to replace motor as fan power, so that the fan is changed from original electric drive to hydraulic drive, and the special water turbine for cooling tower is installed at the original motor. The main shaft of water turbine is directly connected with the original coupling of cooling tower, and the fan of cooling tower is driven by the original transmission shaft and reducer, cancel the original motor to save electric energy in the cooling tower, then make a bypass on the water pipe entering the cooling tower, introduce the original water flow entering the cooling tower into the water turbine horizontally and axially through the water inlet pipe, valve and expansion joint, drive the water turbine to do work, and then lead the water flow back to the original water distribution pipe, and the original water distribution (or spray) effect will remain unchanged.
After the transformation of the cooling tower, not only will not change the overall structural layout of the cooling circulating water system, but also because the cooling tower turbine design is rigorous, the structure is reasonable, and the operation is stable, it can fundamentally solve the leakage caused by the motor, electric control and reducer., Oil leakage, burning and damage failures provide a guarantee for safe and continuous operation, and can operate safely in any explosion-proof environment.
The waste heat generated in industrial production or refrigeration process is generally guided away by cooling water. The function of the cooling tower is to exchange heat between the cooling water carrying waste heat and the air in the tower, so that the waste heat is transferred to the air and scattered into the atmosphere. The glass fiber reinforced plastic cooling tower is simply a device that uses cooling water to return the waste generated in the light industrial consumption or allowed in the refrigeration process, which is roughly similar to that in a thermal power plant, it is to use FRP cooling tower to stop heat exchange between the cooling water with waste heat and the atmosphere in the tower, and then dissipate the waste heat into the atmosphere. FRP cooling tower is suitable for a wide range of applications. Apart from thermal power plants, there are also air conditioning cooling systems, freezing systems and other industries, which are mainly composed of motors, blades, water pipes, water dispensers, fillers and other devices. Under abnormal conditions, the cooling water is repeatedly sent to the cooling tower through the pump, the motor helps the wind blades to wind at high speed and hit the cooling water repeatedly, causing the water column to have a "spray" effect, thus cooling down.
Cooling tower as a kind of equipment to disperse refrigeration and air conditioning or industrial waste gas, plays an important role, especially in today's industrial development is accelerating, people's living standards continue to improve, pay attention to energy conservation and environmental protection, become more and more people's pursuit.
Controlling water resources, saving scarce resources, and realizing full utilization of resources, FRP cooling towers have been widely used. They have corrosion resistance, high strength, light weight, small footprint, and are convenient for transportation, installation and maintenance. Cooling water circulation systems such as air conditioning, refrigeration, air compressor stations, cooling tower heating furnace and condensation process are particularly suitable. In summary, FRP cooling towers are more and more widely used by people.
1, reliable: external turbine unique, rational design, installed outside the cooling tower duct, easy maintenance, structure and traditional cooling tower motor, reducer the same, cancel the traditional motor mechanical noise and failure rate, smooth operation, high reliability.
2, cold efficiency guarantee: with the change of the season, the cooling system will change, the external turbine unique design of three brake valve so that the fan speed increases or decreases with the increase or decrease of the circulating water flow, the air volume also increases or decreases, so that the cooling tower air-water ratio is stable in the best state, to achieve the best operation effect.
3. Environmental protection: After the external hydraulic turbine replaces the motor, it reduces mechanical noise and vibration and reduces user energy.
4. Energy saving: Make full use of the return water pressure of the circulating water system to convert into mechanical energy, and the external water turbine replaces the motor drive to achieve 100 energy saving.
5. Safety: Fundamentally eliminate the failure of motor, electric control and leakage burning damage, provide a guarantee for safe and continuous operation, and can operate safely in any environment that requires explosion-proof.
