Abstract

The invention relates to a long-distance general-circulation graded heat supply system. The long-distance general-circulation graded heat supply system comprises a powder plant waste heat center heat-exchange station, wherein the powder plant waste heat center heat-exchange station is connected with a first-grade heat supply pipeline, a first-grade water return pipeline is arranged beside the first-grade heat supply pipeline, a second-grade heat supply pipeline is connected to the first-grade water return pipeline, a second-grade water return pipeline is arranged beside the second-grade heat supply pipeline, a third-grade heat supply pipeline is connected with the second-grade water return pipeline, a third-grade water return pipeline is arranged beside the third-grade heat supply pipeline, the third-grade heat supply pipeline is connected with a plurality of grades of heat source units in sequence, the diameter of the first-grade heat supply pipeline, the diameter of the second-grade heat supply pipeline and the diameter of the third-grade heat supply pipeline become smaller gradually from the heat end to the tail end, and the diameter of the first-grade water return pipeline, the diameter of the second-grade water return pipeline and the diameter of the third-grade water return pipeline become larger gradually from the heat end to the tail end. The long-distance general-circulation graded heat supply system has the advantages that long-distance transportation of the heat sources can be achieved, the heat supply coverage is large, a large number of medium and small coal-fired boilers can be omitted, pollution caused by medium and small coal-fired boilers is reduced, and the heat supply quality can be guaranteed for urban residents.

Description

(1) Technical field [0001] The invention belongs to the technical field of heat supply by utilizing waste heat of a power plant, and in particular relates to a remote large-cycle graded heat supply system. (2) Background technology [0002] In a heating system that takes the sensible heat of hot fluid (such as hot water) as the heat load delivery method, multiple heat exchanges are required, and multiple coal-fired boilers need to be used for heat exchange in the system, which wastes resources and causes serious pollution; and the return The water temperature is high, and from the perspective of comprehensive utilization of heat energy, the existence of a small temperature difference is unreasonable; long-distance heat transmission cannot be carried out, and the heating area covered is small, which greatly wastes energy and labor costs. (3) Contents of the invention [0003] In order to make up for the deficiencies of the prior art, the present invention provid...
