Description

technical field [0001] The invention relates to a heat supply system, in particular to an energy-saving organic heat carrier dynamic heat energy intelligent distribution system. Background technique [0002] The organic heat carrier boiler is a new, safe, high-efficiency, energy-saving, low-pressure (atmospheric or lower pressure) special industrial furnace that can provide high-temperature heat. Heat is transferred to heat-consuming equipment. [0003] The organic heat carrier energy system is composed of an organic heat carrier boiler, a thermal oil circulation pump, a heat transfer oil pipeline network, heat utilization equipment, a heat transfer oil return pipeline network, a three-way regulating valve and an expansion buffer tank to form a closed loop system. The effective utilization rate of heat energy for indirect heating is about 25-30% higher than that of the open-circuit heating system using saturated steam as the heat carrier, and it can also provide a higher pr...

Problems solved by technology

Since more oil is poured back to the boiler by the bypass circuit, some equipment that consumes a lot of heat in an instant cannot guarantee the heat demand of the process and the process temperature without getting more oil.

[0009] 3. When the energy system is started cold, or when new oil is injected into the system, the oil pump will "vacate" and cause the pipeline to resonate and produce axial movement, endangering the safety of the boiler and pipeline
