[0001] The utility model relates to the technical field of furfural production, in particular to a device for denitrification of a furfural boiler. Background Technique

[0002] Furfural is an organic compound, a colorless and transparent oily liquid with a special smell similar to that of benzaldehyde. It is mainly used as an industrial solvent and can also be used to prepare furfuryl alcohol, furoic acid, tetrahydrofuran, γ-valerolactone, pyrrole, tetrahydropyrrole, etc.

[0003] Furfural residue is the waste after furfural production. In the process of furfural production, most enterprises discharge furfural residue and waste gas into the slag shed together, and the waste gas is directly discharged into the atmosphere, causing air pollution and failing to meet the requirements of clean production.

[0004] In the existing flue gas treatment method, during the process of filtering flue gas, impurities in the flue gas are removed by spray dust removal, which leads to the need for secondary filtration of water before it can be used again, resulting in waste of water resources.

[0005] Therefore, we propose a device for denitrification of a furfural boiler to solve the existing problems. Content of the Utility Model
