The combination air cooler comprises a case, a wet and cold portion, an air inlet, a spraying water tank, a technical medium outlet, a dry and cold portion, a hyperbolic air duct and a technological medium inlet, the wet and cold portion, the air inlet and the spraying water tank are sequentially arranged in the case from top to bottom, the technological medium outlet is positioned on one side of the case and led out from the wet and cold portion, the wet and cold portion sequentially consists of a spraying system and an evaporation cooling tube bundle from top to bottom, the evaporation cooling tube bundle consists of heat exchange tubes which are obliquely arranged, an included angle is formed between each heat exchange tube and the horizontal plane, the dry and cold portion is positioned above the wet and cold portion, the hyperbolic air duct is arranged above the dry and cold portion, and the technological medium inlet is positioned on one side of the case and led into the dry and cold portion. The circulating cooling water system based on the air cooler consists of a technological device cooler, a water pool, a circulating water pump and the combination air cooler which are sequentially connected along a circulating direction of sealed circulating technological media in the circulating cooling water system. The combination air cooler, the circulating cooling water system and the method have the advantages that electricity consumption and water consumption are saved during production, and an energy conservation effect is realized.

Description

technical field [0001] The invention relates to an air cooler and a circulating cooling water system and method based on the air cooler, in particular to a combined air cooler and the circulating cooling water system and method based on the combined air cooler. Background technique [0002] The existing circulating cooling water system in the field of calcium carbide production such as figure 1 As shown, the circulating cooling water system is based on a cooling tower 101 . Cooling tower 101 adopts soft water spray cooling, needs to consume soft water throughout the year. Moreover, since the cooling tower 101 is an open structure, the water droplets splashed out of the system during the spraying process will generate a large amount of evaporation in contact with the environment, so the evaporation consumption of soft water is very large. This structure not only consumes a large amount of water resources, but also greatly increases the operating load of the spray pump and f...

AI Technical Summary

Problems solved by technology

Moreover, since the cooling tower 101 is an open structure, the water droplets splashed outside the system during the spraying process will produce a large amount of evaporation when the soft water contacts with the environment, so the evaporation consumption of soft water is very large

This structure not only consumes a large amount of water resources, but also greatly increases the operating load of the cooling tower spray pump and fan, thereby increasing power consumption

In addition, the process medium after absorbing heat from the high-temperature material in the process device cooler 102 needs to be pumped into the cooling tower 101 through the hot water pool 103 and the hot water pump 104, and needs to pass through the cold water pool 105 and the cold water pump 106 after being cooled by the cooling tower 101. The pressurized pump is pumped into the process unit cooler 102, wherein the operation of the hot water pump 104 and the cold water pump 106 requires power consumption

Therefore, the above compositional structures will cause waste of energy and affect the production cost of calcium carbide products

[0003] In addition, Xining, Qinghai is located at a high altitude and belongs to an alpine region. There are many days with a temperature below 0°C throughout the year. It is a serious problem to prevent freezing of the circulating cooling water system based on cooling towers.
