The effect of gas purification efficiency.

Description

technical field [0001] The invention relates to the technical field of dust removal mechanical equipment, in particular to an energy-saving and environment-friendly treatment system for high-temperature flue gas. Background technique [0002] Smoke is a mixture of gas and smoke and is the main cause of air pollution in residential areas. The composition of the flue gas is very complex. The gas includes water vapor, sulfur dioxide, nitrogen, oxygen, carbon monoxide, carbon dioxide, hydrocarbons, and nitrogen oxides. The smoke includes fuel ash, coal particles, oil droplets, and high-temperature cracking products; Flue gas not only has the above characteristics, but also has high temperature and complex composition. The temperature of high-temperature flue gas can reach several hundred degrees Celsius, and the heat energy generated can be put into other production and life for utilization. [0003] At present, the existing solution for the treatment of high-temperature flue g...

Problems solved by technology

[0004] The above existing technical solutions have the following defects: mixing cold air into the pipeline will lead to an increase in the amount of flue gas, and the greater the cooling range, the greater the volume of flue gas will increase, which will increase the burden on equipment operation and reduce the efficiency of flue gas purification treatment ; The large amount of heat energy carried in the high-temperature flue gas is not utilized, resulting in a certain waste of energy consumption, and the effect of energy saving and environmental protection has not been achieved
