Implementation of pulse heat supply for dependent connection of customers

Abstract

This article deals with organization of pulsed and fluctuating circulation of heat-carrying agent in separate sections of heat supply system with dependent connection of customers. These types of oscillatory motion of the heat-carrying agent are proposed to be carried out in a self-sustained operation on the basis of the hydraulic ram operation principle. The relevance of the subject-matter is determined by the influence of oscillating flows on the intensity of heat exchange processes and by the possibility of using the circuit design of hydraulic ram in order to improve energy efficiency of heat supply systems. Analysis of the technical solution of a single-fluid hydraulic ram is carried out and conditions for ensuring its possible operation in a closed hydraulic circuit are determined. A sequential transition is shown for the use of this water-lifting device in the heat supply system with dependent connection of customers for organization of pulsed and fluctuating circulation of the heat-carrying agent in its separate sections. The research results form a unified view of technical realization method of the vibrational circulation of the heat-carrying agent in a self-sustained operation in separate sections of the heat supply system with dependent connection of heat consumption systems. Taking into account the achievement of intensification of heat exchange processes in these conditions, self-cleaning of heat exchange surfaces and possible strengthening of pressure in the heat consumption system only at the expense of the available pressure of the heat network, it is concluded that application of the circuit design of the hydraulic ram in the heat supply system can be used to increase its energy efficiency.

В статье рассматривается организация импульсной и пульсирующей циркуляции теплоносителя на отдельных участках системы теплоснабжения с зависимым присоединением абонентов. Указанные виды колебательного движения теплоносителя предлагается осуществлять в самоподдерживающемся режиме на основе принципа действия гидравлического тарана. Актуальность тематики обусловлена влиянием колеблющихся потоков на интенсивность теплообменных процессов, а также возможностью использования схемного решения гидравлического тарана применительно к повышению энергетической эффективности систем теплоснабжения. Выполнен анализ технического решения одножидкостного гидравлического тарана, определены условия для обеспечения его возможной работы в замкнутом гидравлическом контуре. Показан последовательный переход к использованию данного водоподъемного устройства в системе теплоснабжения с зависимым присоединением абонентов для организации импульсной и пульсирующей циркуляции теплоносителя на ее отдельных участках. Результаты исследования формируют единое представление о способе технической реализации колебательной циркуляции теплоносителя в самоподдерживающемся режиме на отдельных участках системы теплоснабжения с зависимым присоединением систем теплопотребления. С учетом достигаемых в этих условиях интенсификации теплообменных процессов, самоочищения теплопередающих поверхностей и возможного усиления напора в системе теплопотребления только за счет располагаемого напора тепловой сети, делается вывод о том, что применение схемного решения гидравлического тарана в системе теплоснабжения может быть использовано к повышению ее энергетической эффективности.
