Abstract

The invention discloses a system for efficiently recovering industrial low-temperature waste heat and flexibly regulating the peak for new energy. According to the system, low-temperature steam heat is recovered through the steam compression technology, the working capacity and entropy of steam are improved through steam compression, the pressure of the steam is improved, high-temperature heat can be released and utilized, and high-temperature hot coal is provided. A steam compressor is driven by steam and a synchronous motor, when a power grid needs to carry out new energy consumption and peak regulation, the steam load can be reduced, the power load of the synchronous motor can be increased, new energy power can be absorbed, new energy peak regulation service can be provided for the power grid, and meanwhile, zero-carbon recovery of a low-temperature heat source can be achieved; the system is mainly used for efficiently recovering low-temperature flue gas waste heat, energy is converted into heat energy of heat supply network water to the maximum extent, and due to the fact that latent heat of vaporization of flue gas water vapor is absorbed, the boiler efficiency calculated according to the low-level calorific value can be improved to 100%.

Description

technical field [0001] The invention belongs to the technical field of efficiently recovering low-temperature waste heat and supplying thermal coal, and specifically relates to a system for efficiently recovering industrial low-temperature waste heat and flexible peak regulation for new energy. Background technique [0002] Industrial low-temperature waste heat refers to the waste heat that needs to be discharged to the atmosphere in industrial production, such as exhaust air from steam turbines, heat from industrial cooling water, exhaust air from low-temperature evaporation, etc. The flexible peak shaving system for new energy refers to a system that realizes real-time adjustment of power load for new energy consumption according to the real-time output load of new energy in the power grid. [0003] But now low-temperature heat energy recovery systems, mainly lithium bromide heat pump systems, generally use 10-70°C hot water, which can obtain hot coal that is 40°C higher t...
