Abstract
Изобретение относитс к централизованному теплоснабжению жилых и общественных зданий. Цель изобретени - снижение затрат на транспортировку теплоносител . Предлагаемый спсоб, включающий регулирование тепловой нагрузки путем введени в сетевую воду добавки, снижающей гидравлическое сопротивление сети, позвол ет снизить ее расход при режимах, близких к расчетному. 1 ил.This invention relates to the centralized heat supply of residential and public buildings. The purpose of the invention is to reduce the cost of transporting the coolant. The proposed method, which includes regulation of the heat load by introducing into the network water an additive that reduces the hydraulic resistance of the network, makes it possible to reduce its consumption under conditions close to the design one. 1 il.

Изобретение относитс к системам централизованного теплоснабжени .This invention relates to district heating systems.
Цель изобретени - снижение затрат на транспортировку теплоносител The purpose of the invention is to reduce the cost of transporting the coolant
На чертеже показана принципиаль- на схема устройства дл реализации предлагаемого способа.The drawing shows a schematic diagram of the device for implementing the proposed method.
Устройство содержит котлоагрегат 1, подающий 2 и обратный 3 трубопроводы , сетевой насос 4, регул тор 5 с датчиками температуры наружного воздуха 6 и сетевойводы 7, регул тор 8 расхода сетевой воды, клапан 9, расходомер 10, датчик 11 температуры, расходную емкость 12 и насос 13 дл подачи добавки.The device contains a boiler 1, supplying 2 and 3 return pipelines, a network pump 4, a controller 5 with outdoor temperature sensors 6 and a network drive 7, a controller 8 for the flow of network water, a valve 9, a flow meter 10, a temperature sensor 11, a supply tank 12 and pump 13 for supplying an additive.
Способ осуществл ют следующим образом .The method is carried out as follows.
Регулирование тепловой нагрузки в диапазоне от О до 0,8-0,9 номиналь ной осуществл етс путем изменени температуры сетевой воды в подающей магистрали за счет изменени расхода топлива с помощью регул тора 5. Расхо сетевой воды при этом поддерживаетс посто нным.The regulation of the heat load in the range from 0 to 0.8-0.9 nominal is carried out by changing the temperature of the supply water in the supply line by varying the fuel consumption with the help of the controller 5. The flow rate of the supply water is kept constant.
В диапазоне тепловых нагрузок выше 0,8-0,9 номинальной регулирование осуществл ют путем изменени расхода сетевой воды путем введени в сетевую воду добавок, снижающих гид- :равлическое сопротивление, например,In the range of heat loads above 0.8-0.9, the nominal regulation is carried out by changing the flow rate of the network water by introducing into the network water additives that reduce the hydraulic resistance, for example,

полиакриламид. С ростом тепловой нагрузки его концентрацию в сетевой воде измен ют от О до 1,10 кг/кг. Регулирование расхода сетевой воды осуществл ют клапаном 9, управл емым регул тором 8, св занным с датчиком 11 и расходомером 10.polyacrylamide. With increasing heat load, its concentration in the supply water varies from 0 to 1.10 kg / kg. The flow rate of the supply water is controlled by a valve 9 controlled by the regulator 8, connected to the sensor 11 and the flow meter 10.
Добавку, снижающую гидравлическое сопротивление., подают из расходной емкости 12 с помощью насоса (дозатора ) 13. Предлагаемый способ позвол ет снизить затраты на перекачку теплоносител .An additive that reduces the hydraulic resistance. Is supplied from the supply tank 12 by means of a pump (metering device) 13. The proposed method allows to reduce the cost of transferring the coolant.
