Problems solved by technology
In order to meet the requirements of the latest national ultra-low emission standards, the wet desulfurization process with high desulfurization efficiency is usually used to desulfurize and denitrify the flue gas, and the flue gas has a lot of heat after the combustion furnace is discharged. Emissions will cause a great loss of energy, so in order to solve this problem, it is particularly important to design a waste heat recovery system for flue gas desulfurization and denitrification

Embodiment Construction
[0018] like figure 1 The shown waste heat recovery system for flue gas desulfurization and denitrification includes a pretreatment box 1, a flue gas delivery box 5, a spray treatment tower 11, a recovery box 26 and a heat exchange pipe 25. The pretreatment A first activated carbon storage seat 2 is arranged in the processing box, a second activated carbon storage seat 12 is arranged in the spray treatment tower, and a A storage channel for storing activated carbon that runs through up and down. A grid restricting plate 22 is arranged in the spray treatment tower below the second activated carbon storage seat. The grid restricting plate is placed horizontally and connected to the second activated carbon storage seat. The bottom of the storage channel is in contact with the bottom, the activated carbon in the storage channel is restricted in the activated carbon storage seat by the grid restriction plate, and the flue gas can enter the storage channel through the grid restrictio...

The invention provides a waste heat recovery system for flue gas desulfurization and denitrification. The system is characterized in that the waste heat recovery system comprises a pretreatment box body, a flue gas conveying box body, a spraying treatment tower, a recovery box body and a heat exchange pipeline, a first activated carbon storage seat is arranged in the pretreatment box body, a second activated carbon storage seat is arranged in the spraying treatment tower, vertically through storage channels for storing activated carbon are formed in the first activated carbon storage seat and the second activated carbon storage seat, and a grid limiting plate is arranged in the spraying treatment tower below the second activated carbon storage seat. The first flue gas conveying pipeline and the second flue gas conveying pipeline in the design are each formed by connecting the multiple Tesla valve pipes end to end, the flue gas conveying speed is increased through the special structures of the Tesla valve pipes, and loss of heat in the conveying process is reduced.
Description
technical field [0001] The invention relates to the technical field of flue gas desulfurization and denitrification, in particular to a waste heat recovery system for flue gas desulfurization and denitrification. Background technique [0002] During the production process of iron ore agglomeration or coal combustion for power generation, the sulfur in the material will be oxidized to form sulfur dioxide or sulfur trioxide and enter the flue gas. In order to meet the requirements of the latest national ultra-low emission standards, the wet desulfurization process with high desulfurization efficiency is usually used to desulfurize and denitrify the flue gas, and the flue gas has a lot of heat after the combustion furnace is discharged. Emission will cause a great loss of energy, so in order to solve this problem, it is particularly important to design a waste heat recovery system for flue gas desulfurization and denitrification. Contents of the invention [0003] The presen...
