Energy management internet managed waste heat driven power generation, heating, cooling, vapor generation, water generation, material manufacturing and sewage treatment cogeneration system

Abstract

The invention discloses an energy management internet managed waste heat driven power generation, heating, cooling, vapor generation, water generation, material manufacturing and sewage treatment cogeneration system. According to the system, heat recovery devices of various types are integrated, and the devices are enabled to be multi-functional; an energy management internet is established for remote energy management; the integrated system continuously switches and recycles industrial waste heat and environmental released heat, and outputs the functions such as power generation, heating, cooling, vapor generation, water generation, material manufacturing and sewage treatment in divided periods and continuously according to technological requirements; hot water with various temperatures is provided; and the basis industrial power requirement is met on line, the driving energy consumption, environmental released heat, transmission loss and system investment are reduced, the energy saving and environmental protection are achieved simultaneously, the system use ratio and return rate are improved in multiplies, and the investment payoff period is shortened.

Description

(1) Technical field [0001] The invention relates to a system capable of networking management waste heat to drive electric heating, cold steam, water, material and sewage joint supply. (2) Background technology [0002] Definition of industrial waste heat: the inevitable product of heat and material imbalance in the process, distributed in multiple points in the factory area, 80-300 ℃ and continuously provided throughout the year. [0003] Waste heat grade and utilization efficiency: heat carrier inlet and outlet temperature; [0004] Heat carrier: liquid, gas, water vapor; [0005] Waste heat: heat carrier flow rate, specific heat, temperature difference between inlet and outlet; [0006] Take the heat exchanger tube: the heat carrier component. [0007] Waste heat extraction method: divided into direct heat extraction and indirect heat extraction. Among them, the intermediate heat exchanger and intermediate circulation pump are omitted for direct heat extraction, which...

AI Technical Summary

Problems solved by technology

[0014] However, power generation, heating, refrigeration, steam production, water production, material production, sewage treatment, etc., as the seven basic industrial power needs, often appear in combination in time periods. Therefore, if each heat recovery equipment only outputs a single function, it cannot be recovered continuously The waste heat cannot be continuously output; in addition, the grade of waste heat is low, and the heat carrier is corroded seriously, which leads to low utilization rate of heat recovery equipment, low return rate, large investment amount, long payback period and other difficulties, which limit its Industrial waste heat is recovered and utilized at the equipment level rather than at the system level, so it is difficult to achieve full-scale promotion
