Embodiment 1

[0103] Do not start the steam peak shaving boiler mode, the structure is as follows figure 1 As shown, the high-temperature heat pump heating device 27 from the process device heat or steam source enters the waste heat energy control center 28 through the high-temperature waste heat energy heating pipeline 48, and then distributes one path through the high-temperature waste heat energy to 8 heat supply pipelines 41 to transfer heat Released into the perennial heat system 8, the cooling return water passes through the high-temperature waste heat energy to the 8 return water pipeline 42 and returns to the high-temperature waste heat energy control center 28, and the other way passes through the high-temperature waste heat to the 1 heating pipeline 43 and enters the famous steam furnace Room 1 releases heat, and after cooling, the return water passes through the high-temperature waste heat energy to return water line 44 to return to the high-temperature waste heat energy control ...

Embodiment 2

[0106] Start the steam boiler operation mode, its structure is as follows figure 1 As shown, the thermal flow of high-temperature waste heat energy is exactly the same as that of Example 1 before the return water is collected and enters the steam-driven source heat pump device 11, the difference is that the steam generated by the steam boiler room 1 passes through the steam output pipeline 19 and passes through the back pressure device After the 1A decompression is used, it is divided into two routes and one route passes through the back pressure recycling steam pipeline 20 to the steam boiler room as a heat source for heating the first-level network heat supply return water and outputting to the perennial heat system 8 .

[0107] A back pressure steam driving source pipeline 21 provides a driving source for the steam driving source heat pump device 11 .

[0108] After the waste heat energy is utilized, it is collected in the return water pipeline 13 and enters the low-temper...

Embodiment 3

[0119] Embodiment 3, start the steam boiler mode, increase the excess waste heat energy utilization device mode, the structure is as follows figure 2 The operation process shown is basically the same as that of Example 2, except that the heat energy provided by the enriched high-temperature cooling circulating water or the electric heat pump heating device 25A passes through the enriched high-temperature cooling circulating water or the electric heat pump heating pipeline 13B to a low temperature. Use the heat zone 3 to release heat, and then heat the low-temperature heat source of the heat pump after enrichment heating and cooling, and then pass through the enrichment steam heat pump and then the low-temperature heat source pipeline 23A to the electric drive heat pump device 12 to provide low-temperature heat source for it, and then supply the heat back through the enrichment waste heat The water pipe 14 goes to the Fuji low-temperature cooling circulating water heating devic...

Abstract

The invention relates to a dual-source complementary multi-net linkage residual heat and waste heat energy central heating system. The system comprises a residual heat and waste heat energy regulating and controlling center and a plurality of stages of residual heat and waste heat energy collecting devices, and is characterized in that a steam boiler room, a back pressure device, a low-temperature steam driving source heat pump device, an electrically driven heat pump device, other heating network low-temperature heat using devices in an area, a low-temperature heat using adjusting area and a whole-year heat using system are arranged between the residual heat and waste heat energy regulating and controlling center and the residual heat and waste heat energy collecting devices in a communicating mode in sequence. By means of the dual-source complementary multi-net linkage residual heat and waste heat energy central heating system, the residual heat and waste heat energy in the area is fully utilized, energy is saved, the working high-temperature heating value of fossil fuel is shown, and enormous economic benefits are achieved on the premise that energy consumption is substantially reduced.

Description

technical field [0001] The invention relates to a central heating system that uses industrial high-temperature waste heat energy to integrate multiple heat-using functions in its area, specifically a dual-source multi-network linkage large temperature difference waste heat energy centralized heating system method. Background technique [0002] Currently, there are year-round and seasonal multiple fossil fuel boilers operating alone in the same area, and there is even a large amount of industrial waste heat nearby that exceeds its application temperature. It also needs to be discarded into the environment through resource-consuming cooling methods, which is not in line with the spirit of circular combined production among energy-saving and emission-reducing industries. Contents of the invention [0003] The purpose of the present invention is to solve the above problems, and propose a dual-source multi-network linkage large temperature difference waste heat energy centraliz...
