Abstract
Изобретение относится к области теплотехники и может быть использовано в различных отраслях, требующих охлаждения различных аппаратов и устройств при минимальных расходах охладителя, например воды. Одним из наиболее важных применений предполагаемого изобретения может быть, например, повышение эффективности процесса генерации водяной плазмы путем повышения термического КПД водяных плазмотронов до уровня, близкого к 100%, а также улучшение их эксплуатационных характеристик за счет повышения точности и упрощения процессов регулирования их рабочих режимов. Поставленная задача применительно, например, к плазмотрону решается путем использования испарительного его охлаждения вместо традиционного конвективного, работающего только за счет теплоемкости воды, для чего воду, предназначенную для охлаждения плазмотрона и генерации плазмы, нагревают во внешнем водонагревателе под давлением ниже критического до температуры ниже точки кипения при этом давлении, подают нагретую воду или другую жидкость в систему охлаждения, например охлаждающий тракт одного из электродов, где дросселируют эту воду до давления ниже давления насыщенного пара при температуре нагрева воды и продолжают дросселирование полученного влажного пара на всем протяжении охлаждающего тракта вместе с нагревом пара, регулируя его расход регулированием расхода воды на входе в тракт в соответствии с потребностями охлаждения электрода.The invention relates to the field of heat engineering and can be used in various industries requiring the cooling of various apparatuses and devices with minimum flow rates of a cooler, for example water. One of the most important applications of the proposed invention can be, for example, increasing the efficiency of the water plasma generation process by increasing the thermal efficiency of water plasmatrons to a level close to 100%, as well as improving their operational characteristics by increasing the accuracy and simplifying the processes of regulating their operating modes. The problem posed as applied, for example, to a plasmatron, is solved by using evaporative cooling instead of traditional convective, working only due to the heat capacity of the water, for which water intended for cooling the plasma torch and plasma generation is heated in an external water heater under a pressure below critical to a temperature below the boiling point at this pressure, heated water or another liquid is fed into the cooling system, for example, the cooling path of one of the electrodes, where this water is throttled to a pressure below the saturated steam pressure at the water heating temperature and the throttled wet steam is continued to be throttled along the entire cooling path along with steam heating , adjusting its flow rate by regulating the flow rate of water at the entrance to the tract in accordance with the needs of cooling the electrode.
