МЕТОДЫ. При решении поставленной задачи использовались законы сохранения тепла и массы, балансовые соотношения при расчете экономических затрат.

РЕЗУЛЬТАТЫ

РЕЗУЛЬТАТЫ. В статье описана актуальность темы, рассмотрены особенности работы теплообменного аппарата, в котором происходит передача тепла от конденсирующейся парогазовой смеси, содержащей твердые частицы. Сделано предположение о механизме осаждения этих частиц на поверхность теплообмена. Получена зависимость, позволяющая определить время, через которое нужно восстанавливать поверхность с учетом стоимости воды и электричества.

ЗАКЛЮЧЕНИЕ

ЗАКЛЮЧЕНИЕ. Исследования позволили предположить механизм формирования осадка на поверхности теплообмена. Выбор рационального режима эксплуатации теплообменного аппарата позволит значительно сэкономить расход воды на восстановление поверхности, а также извлечь наибольшее количество тепла из парогазовой смеси. Выброс частиц в воздушную среду может быть снижен.

THE PURPOSE

THE PURPOSE. Determine the operating mode of a heat exchanger designed to transfer heat from a vapor-gas mixture containing solid particles. Get a dependency for calculating the time after which it is necessary to restore the surface by washing it with water. To carry out estimated calculations of the operating mode of the heat exchanger installed at the PULP Invest enterprise. To increase the stability of the heat exchanger and reduce environmental pollution by cellulose particles.

METHODS

METHODS. In solving this problem, the laws of heat and mass conservation, balance ratios in the calculation of economic costs were used.

RESULTS

RESULTS. The article describes the relevance of the topic, discusses the features of the operation of a heat exchanger in which heat is transferred from a condensing vapor-gas mixture containing solid particles. An assumption is made about the mechanism of deposition of these particles on the heat exchange surface. A dependence is obtained that allows us to determine the time after which the surface needs to be restored, taking into account the cost of water and electricity.

CONCLUSION

CONCLUSION. Studies have suggested the mechanism of sediment formation on the heat exchange surface. Choosing a rational mode of operation of the heat exchanger will significantly save water consumption for surface restoration, as well as extract the greatest amount of heat from the steam-gas mixture. The release of particles into the air can be reduced.
