Abstract

The invention discloses a flue gas waste heat recovery system for solar energy and wind energy hybrid-driven mechanical compression type heat pump circulation. The system comprises a gas boiler, an air preheater, a mechanical compression type heat pump device, a wind turbine device and a solar battery pack. Compared with the prior art, the system has the advantages that by utilizing a wind energyand solar energy hybrid driving mode, the temperature of supplied water is increased, and the heat absorption amount of the supplied water in the boiler is reduced, so that the gas amount is reduced,and the purposes of energy conservation and emission reduction are achieved.

Description

technical field [0001] The invention relates to a heat recovery device, in particular to a flue gas waste heat recovery system driven by a new energy-driven mechanical compression heat pump cycle. Background technique [0002] In order to change the air pollution caused by coal-fired heating in Urumqi in winter, since 2010, Urumqi has launched a "coal-to-gas" project. The implementation of the "coal-to-gas" project has resulted in the blue sky and white clouds in Urumqi. At present, the heating ratio of clean energy in Tianshan District, Shayibake District, High-tech Zone (New District), Shuimogou District, and Midong District in the main urban area of ​​Urumqi has reached 100%, completely realizing natural gas heating, becoming the first in the country A city heated by natural gas. As of the heating period in 2014, a total of more than 700 gas-fired boilers with a hot water capacity of 100,000 to 1 million tons have been installed. These gas-fired boilers absorb the waste...
