Abstract

The invention discloses a flue gas heat accumulation and denitrification device and a denitrification method for an industrial furnace. The flue gas heat accumulation and denitrification device comprises a first heat accumulation portion and a second heat accumulation portion, wherein a high-temperature heat accumulator is arranged in the heat accumulation portion, and a first opening is formed in the upper portion of the heat accumulation portion; and the second heat accumulation portion is successively divided into an ammonia spraying region and a denitrification and heat accumulation region from bottom to top, a reducer nozzle is arranged in the ammonia spraying region, a denitrification and heat accumulator is arranged in the denitrification and heat accumulation region, a second opening is formed in the upper portion of the second heat accumulation portion, and the bottom end of the second heat accumulation region is communicated with the bottom end of the first heat accumulation portion. The flue gas heat accumulation and denitrification device for the industrial furnace integrates a heat accumulating combustion system and the flue gas denitrification system, so that the denitrification treatment on the flue gas is realized while flue gas waste heat is recovered. The flue gas heat accumulation and denitrification device has double functions of heat accumulation and denitrification.

Description

technical field [0001] The invention belongs to the field of gas denitrification, energy saving and environmental protection. Specifically, the invention relates to an industrial furnace flue gas thermal storage denitrification device and a denitrification method. Background technique [0002] With the rapid development of my country's economy, fossil fuels such as natural gas, oil and coal have been more widely used, making environmental problems increasingly serious, which has caused a series of environmental problems, such as acid rain, ozone layer destruction, greenhouse effect, etc., making us The living environment is becoming more and more severe. my country's coal-based energy structure determines that the emissions of nitrogen oxides and sulfur oxides in our country have always been high. The emission of a large amount of polluting gases has made environmental problems increasingly serious, not only seriously affecting the production and life of our people. , and is ...
