The invention discloses a pressure-separation type large-temperature-difference heat supply device and a heat supply method. The heat supply device includes a first heat pump, a second heat pump, anda heat exchanger; the first heat pump comprises a first cooler, a first heater and a second cooler; the second heat pump includes a third cooler and a second heater; the first cooler sequentially communicates with the heat exchanger, the second cooler and the third cooler, and the first cooler is connected to an upstream heat source; any two of the first heater, the second heater and the heat exchanger communicate with each other, or the first heater, the second heater and the heat exchanger are joined together to be connected to a downstream hot user. According to the device and method, largetemperature difference heat supply can be carried out on a relay energy station, on the premise of ensuring the heat supply parameter of the downstream hot user, the temperature of primary return water is reduced; and meanwhile, a plurality of energy sources such as fuel gas, steam and electric energy existing in the relay energy station are fully utilized, the water return temperature is furtherreduced, the water supply and water return temperature difference is increased, and the energy consumption of a backbone network is reduced.
Description
technical field [0001] The invention belongs to the technical field of heat supply, and in particular relates to a pressure-isolated large temperature difference heat supply equipment and a heat supply method. Background technique [0002] With the continuous increase of urban heating area and the rapid growth of heat load demand, the existing pipeline network of central heating system has been difficult to meet the demand due to the limitation of flow and temperature. In order to meet the heating requirements, it is necessary to start from the two aspects of increasing the flow rate or increasing the temperature difference. However, increasing the flow rate requires re-laying pipelines, which is very costly in cities with dense traffic. Therefore, only by increasing the temperature difference between the heating supply and return water can the transmission and distribution capacity of the pipeline network be increased to meet the heat load without changing the flow rate. d...
