Description

Technical Field

[0001] The utility model relates to the technical field of urea destocking, in particular to an atomizing spray gun device for urea destocking. Background Art

[0002] Urea denitrification is an environmental protection technology widely used in coal-fired power plants, industrial boilers and other fields. Its main purpose is to reduce nitrogen oxide emissions in flue gas to improve environmental quality and protect human health. The flue gas in these places contains a large amount of nitrogen oxides, which pose a serious threat to the environment and human health. Through urea denitrification technology, the nitrogen oxide content in the flue gas can be effectively reduced to meet national environmental protection standards.

[0003] In the urea denitrification treatment of flue gas, a fan-shaped atomizing spray gun is currently used for urea denitrification of flue gas. Although the atomization area and atomization particle size of the fan-shaped atomizing spray gun are better than those of general spray guns, when the fan-shaped atomizing spray gun is currently used, the fan-shaped atomizing spray gun is mostly fixed and installed at the place where it is needed, resulting in serious overlap of the fan-shaped atomization areas between multiple spray guns and serious waste of urea. At the same time, blockage problems often occur when using the urea spray gun, which cannot be completely solved after treatment, resulting in high intensity of cleaning work for employees, and urea cannot be used during cleaning, resulting in reduced work efficiency.

[0004] For this reason, we propose a kind of atomizing spray gun device for urea out of stock. Utility Model Content
