Problems solved by technology
The workload of thermal balance adjustment of the external network is getting bigger and bigger, and it is getting more and more difficult, and it is impossible to completely improve the thermal imbalance of the pipe network.
[0005] In the existing dual-pipe system, users close to the first heating station have large hydraulic power and excessive heat. Due to the pressure loss of the pipeline, the hydraulic power available to users at the end heat exchange station of the external network pipeline is small and the heat is insufficient. thermal imbalance

Embodiment Construction
[0024] The present invention as figure 1 shown.
[0025] A distributed heating network system with single and double pipes in the same route, including a heating network primary station system 1, a monitoring system and a data center 7, a heat extraction water supply pipe 3 of the heating network primary station system 1, and a first plug at the end of the water supply pipe 3 3-1 sealed; the return pipe 2 is divided into two branches after the cold introduction of the first station system 1 of the heating network, and is divided into the first return pipe branch 2-1 and the second return pipe branch 2-3. The ends are sealed with the second plug 2-2 and the third plug 2-4 respectively.
[0026] The water supply pipe 3 is divided into a front section, a middle section, and a final section.
[0027] The front section of the water supply pipe 3, the first return pipe branch 2-1 and the first heat exchange station group 4 form the first double pipe system; the inlet and outlet pi...

The invention provides a single and double tube same course distributed heat supply network system. The outer net of the system is in a form of paving single and double tubes. Heat exchange stations are distributed variable frequency intelligent heat exchange stations, a data monitoring center is established in the system, and the whole system is transversely adjusted; each heat exchange station is provided with an independent water taking pump; the flow of circulating water of the first heating station only needs to be satisfied and the lift of on-way resistance of a pipeline can be overcome, so that the lift and flow of the water taking pump are reduced, and meanwhile, the thermal imbalance problem of a double tube system is further overcome, thereby greatly reducing the investment cost and the operating cost of the system. For the investment of a pipe network, about 50% of construction investment is saved compared with that of a conventional double tube system; the power consumption of the first station is saved by about 50% compared with that of the conventional double tube system; the heat energy consumption is saved by about 50% compared with that of the conventional double tube system; for the operating effect, the thermal imbalance problem is greatly reduced, and the operating effect is higher than that of the double tube system.
Description
technical field [0001] The invention relates to a distributed heating network system with single and double pipes in the same course in a heating system. Background technique [0002] The heat supply system is a system in which the first station of heat exchange is set in the thermal power plant as the heat source, and the hot water produced by the condenser and the peak heater of the power plant is used as the medium to deliver heat to the primary heat network, and then the heat is delivered to the heat user through the secondary heat network. . [0003] With the strengthening of the awareness of environmental protection in urban construction, the central heating system with large heat sources has gradually replaced the direct supply system with small heat sources; Increase leads to increased investment and highlights the problem of heat network management. [0004] The traditional central heating one-network system adopts a double-pipe system for supply and return water,...
