Description

Technical Field

[0002] Flue gas is a mixture of gas and smoke, and is the main cause of atmospheric pollution in residential areas. The composition of flue gas is very complex. Gases include water vapor, sulfur dioxide, nitrogen, oxygen, carbon monoxide, carbon dioxide, hydrocarbons, and nitrogen oxides, and smoke includes fuel ash, coal particles, oil droplets, and high-temperature cracking products. When flue gas is discharged, it is necessary to cool the flue gas to recycle the heat of the flue gas. However, some existing flue gas cooling devices generally allow the flue gas to flow through a cooling coil with cooling water. Since the flue gas flow is not constrained, the flue gas will flow through the middle of the cooling coil, and the flue gas cannot contact and cooperate with all parts of the cooling coil. The effective use area of ​​the cooling coil is limited, and there are cooling dead corners, resulting in poor cooling effect and failure to meet actual needs, thereby reducing the use effect.
