Energy conservation and emission reduction method beneficial to carbon neutralization flue gas waste heat recovery and reheating technology

Abstract

The invention provides an energy conservation and emission reduction method beneficial to a carbon neutralization flue gas waste heat recovery and reheating technology. According to the energy conservation and emission reduction method, waste heat recovery and reheating of flue gas are achieved through energy conservation and emission reduction equipment. The energy conservation and emission reduction equipment comprises a waste heat exchange box, wherein a circulating control box is fixedly connected to the front portion of the front wall of the waste heat exchange box and comprises a temperature storage water tank; the temperature storage water tank is fixedly connected to the interior of the circulating control box; the right side of the temperature storage water tank is connected with a low-temperature liquid inlet; the temperature storage water tank comprises a water tank circulating water inlet; the water tank circulating water inlet is formed above the left side of the temperature storage water tank; the water tank circulating water outlet is formed below the right side of the temperature storage water tank; a circulating water pump is arranged in the circulating control box, a water outlet of the circulating water pump is connected with the left side of the temperature storage water tank, and a water inlet of the circulating water pump is connected with a high-temperature liquid outlet; and four sets of inner exchangers are arranged in the waste heat exchange box, recycled heat can be used for preheating production materials, the effects of energy conservation and emission reduction are achieved, meanwhile, the temperature of flue gas is lowered, and pollution caused by the flue gas to the surrounding environment is reduced.

Description

technical field [0001] The invention belongs to the technical field of flue gas treatment, and more specifically relates to an energy-saving and emission-reducing method beneficial to carbon-neutral flue gas waste heat recovery and reheating technology. Background technique [0002] As a new form of environmental protection, carbon neutrality has been adopted by more and more large-scale events and conferences. Carbon neutrality can promote green life and production, and realize the green development of the whole society. In order to better achieve carbon neutrality, the flue gas treatment equipment can be used to treat the flue gas before it is discharged. Among them, there is a cooling method for the flue gas , flue gas filtration and other treatments can reduce the impact of flue gas on the surrounding environment. For example, application number: CN201710251493.X The present invention discloses a flue gas treatment device for chemical smelting equipment. [0003] Based...
