As a relatively active non-metallic element crystal, monocrystalline silicon is an important component of crystal materials and is at the forefront of the development of new materials. The manufacturing of monocrystalline silicon materials goes through the following processes: quartz sand-metallurgical grade silicon purification and refining-deposition of polycrystalline silicon ingots-single crystal silicon wafer cutting. Its main uses are as semiconductor materials and using solar photovoltaic power generation and heating.In the process of making monocrystalline silicon, the monocrystalline silicon furnace needs to maintain a high temperature environment to melt the silicon material and smoothly produce single crystals. However, the higher heating temperature will not only affect the production materials, but also cause thermal stress to the furnace chamber and furnace cover of the monocrystalline silicon furnace, reducing the progress of single crystal production. Therefore, the cooling system of the monocrystalline silicon furnace needs to have efficient, stable and reliable characteristics.The closed cooling tower uses a coil heat exchanger to exchange heat, avoids direct contact between water and air, reduces water evaporation and drift loss, and improves heat exchange efficiency. At the same time, the closed cooling tower can also effectively prevent the growth of scale, dirt and algae, maintain the cleanliness of cooling water, and extend the service life of equipment and pipelines. In addition, the closed cooling tower also has the advantages of environmental protection and water saving, which meets the requirements of modern industry for sustainable development.In the cooling system of the monocrystalline silicon furnace, the closed cooling tower can be used as one of the main cooling equipment. By circulating the cooling water to the cooling part of the monocrystalline silicon furnace, the closed cooling tower can effectively reduce the temperature of the furnace body and furnace cover and other components, and maintain the stable operation of the monocrystalline silicon furnace. At the same time, the closed cooling tower can also automatically adjust the flow and temperature of the cooling water according to the actual needs of the monocrystalline silicon furnace to achieve precise control.It should be noted that when selecting a closed cooling tower, the specific cooling needs and working environment of the monocrystalline silicon furnace need to be considered. For example, the model and specifications of the closed cooling tower need to be determined according to factors such as the power, furnace size, and cooling method of the monocrystalline silicon furnace. In addition, factors such as the water quality requirements, pipeline layout, and maintenance convenience of the cooling system need to be considered to ensure the overall performance and reliability of the cooling system.The above is the relevant content of the closed cooling tower system for cooling the monocrystalline silicon furnace.

High-frequency quenching machine is a professional equipment for metal heat treatment. It mainly uses the heat generated by high-frequency current passing through the inductor to quickly heat the workpiece and then cool it to achieve the purpose of changing the material properties of the workpiece. The cooling process after quenching is the key link to ensure that the material properties reach the expected goals.As a highly efficient heat exchange equipment, closed cooling towers can play an important role in many industrial fields, including cooling and circulating water systems in the metallurgical industry. In the application of high-frequency quenching machine tools, closed cooling towers are mainly used to cool the internal components of high-frequency heating power supplies to ensure the stable operation of the machine tools and the quenching quality.The main advantages of closed cooling towers in high-frequency quenching machine tools:1 Closed circulation does not pollute: The closed cooling tower adopts a closed circulation system, and the circulating medium (such as pure water) flows in a closed pipe, avoiding the problems of water pollution and blockage in traditional open cooling towers. This is especially important for high-frequency quenching machine tools, because the quenching process has high requirements for water quality, and the closed circulation can keep the water quality clean and stable.2. Constant pressure frequency conversion technology: Modern closed cooling towers often use constant pressure frequency conversion technology, which can adjust the cooling water volume and cooling effect according to actual needs, thereby achieving energy saving and consumption reduction.For high-frequency quenching machine tools, this helps to reduce operating costs and improve production efficiency.3 Good cooling effect: The closed cooling tower takes away the heat in the circulating medium and dissipates it into the atmosphere by spraying water and air heat exchange, thereby achieving efficient cooling.This cooling method can quickly reduce the temperature of the internal components of the high-frequency heating power supply and ensure the stable operation of the machine tool in a high-temperature environment.4 Easy to maintain: The structure of the closed cooling tower is relatively simple, and due to the use of a closed circulation system, the generation of scale and impurities is reduced, and the difficulty and cost of maintenance are reduced.This is of great significance for the long-term use of high-frequency quenching machine tools.The closed cooling tower, with its closed circulation, constant pressure frequency conversion, good cooling effect and easy maintenance, provides a strong guarantee for the stable operation and efficient production of high-frequency quenching machine tools.The above is the relevant content of the closed cooling tower system for high-frequency quenching machine tools.

Can the cooling tower not produce white fog when it is running in winter?A closed cooling tower is a device that exchanges heat through heat transfer. When it is running in winter, due to the low ambient temperature, when the gas is discharged from the outside of the tower, the gas temperature will be lower than the dew point temperature, which is easy to produce white fog. As the people's requirements for environmental protection are getting higher and higher, it is required that the cooling tower should not produce white fog when it is running in winter.After many tests, Jiangsu Huata has developed a cooling tower with a combined dew removal and exhaust system, thereby overcoming the defects in the above-mentioned prior art and obtaining a patent.The water vapor fogging point is 0℃ temperature and 100% humidity. When the external environment temperature is higher than 0℃, the hot and humid air in the cooling tower needs to be cooled by the hot air main fan 21 before being discharged. At this time, the discharge will not produce white fog; when the external environment temperature is lower than 0℃ and the humidity of the hot and humid air in the cooling tower is less than 80%, it has not reached the level of fogging and frosting. Because the external environment temperature is low, it is only necessary to turn on the cold air auxiliary fan 22 to discharge the hot and humid air in the cooling tower (it is wasteful to turn on the hot air main fan 21 at this time); when the external temperature is lower than 0℃ and the humidity of the hot and humid air in the cooling tower is greater than 80%, when the humidity of the hot and humid air is slightly higher, the water vapor is easy to reach the fogging and frosting point. At this time, the hot air main fan 21 is turned on, and the cold air auxiliary fan 22 is turned on and reversed to mix the hot and humid air generated by the cooling tower with the dry and cold air of the external environment, so that the humidity of the hot and humid air in the cooling tower can be reduced to below 80%, and then no white fog will be generated when it is discharged from the induced draft duct 24.The opening and closing of the hot air main fan 21 and the cold air auxiliary fan 22 are mainly connected to the electrical appliances of the combined defogging and exhaust system 2 of the cooling tower through the PLC controller 3. After the temperature sensor 25 and the humidity sensor 26 transmit the electrical signals to the PLC controller 3, the PLC controller 3 converts the electrical signals into mechanical signals of the hot air main fan 21 and the cold air auxiliary fan 22, thereby realizing the opening and closing of the hot air main fan 21 and the cold air auxiliary fan 22.The cooling tower is equipped with a combined defogging and exhaust system 2, and the operation of the combined defogging and exhaust system 2 is controlled by the PLC controller 3. On the one hand, even in the cold winter, when the humidity of the outside air is high, the combined action of the hot air main fan 21 and the cold air auxiliary fan 22 can also avoid the phenomenon of white dew in the cooling tower, and the operation is more environmentally friendly. On the other hand, when the outside temperature is low and the humidity of the hot and humid air in the tower is not high, the cold air auxiliary fan 22 can be turned on for exhaust, which is energy-saving and environmentally friendly: the induced draft duct 24 is a shaped structure and the air outlet is downward, which is more conducive to the discharge of the gas generated by the cooling tower.

The anti freezing work of a closed cooling tower in winter is crucial, which not only affects the normal operation of the cooling tower, but also directly affects the stability and service life of the entire cooling system. Therefore, we need to take a series of effective measures to ensure that the closed cooling tower can operate safely and stably in winter.Firstly, we need to strengthen the insulation work of the cooling tower. In winter, when the temperature drops sharply, the water inside the cooling tower is prone to freezing, causing damage to pipelines and equipment. Therefore, we need to insulate the exterior and interior of the cooling tower, wrap the pipes and equipment with insulation materials, reduce heat loss, and maintain stable water temperature.Secondly, we need to regularly check the operating status of the cooling tower. In winter, the operation status of cooling towers may be affected by various factors, such as low temperature, wind and snow. Therefore, we need to regularly check the various parameters of the cooling tower, such as water temperature, water level, flow rate, etc., to ensure that they are within the normal range. At the same time, we also need to inspect various components of the cooling tower, such as water pumps, fans, etc., to ensure that they can work properly.In addition, we can also take some auxiliary measures to prevent the closed cooling tower from icing. For example, installing wind deflectors at the inlet of the cooling tower to reduce the entry of cold air; Install a heater at the bottom of the cooling tower to increase water temperature and prevent icing; Install a drain valve at the outlet of the cooling tower to regularly drain accumulated water and avoid icing.Finally, we need to strengthen the maintenance and upkeep of the cooling water tower. After the end of winter, we need to conduct a comprehensive inspection and maintenance of the cooling tower, replace damaged parts, clean pipelines and equipment, and ensure that the cooling tower can maintain good performance in the next year of use.In summary, the anti freezing work of closed cooling towers in winter requires us to start from multiple aspects and take various measures to ensure the safe and stable operation of the cooling towers. Only in this way can we provide strong guarantees for the stability and service life of the entire cooling system.
