Description

Technical Field

[0001] This utility model relates to the field of spray gun equipment technology, and in particular to a dual-fluid atomizing spray gun. Background Technology

[0002] The purpose of denitrification is to prevent excessive nitrogen oxide pollution from the combustion of materials in pelletizing equipment, thus requiring denitrification treatment of the combustibles. Denitrification can be categorized into pre-combustion denitrification, combustion-process denitrification, and post-combustion denitrification. Existing denitrification methods generally employ rear-end mixing atomizing spray guns and front-end atomizing spray guns.

[0003] In practical applications, existing spray guns have limited functionality, only providing atomization and spraying. They require manual operation by holding the device with both hands, which is time-consuming and labor-intensive. Furthermore, they cannot adjust the temperature according to the atomization scenario, resulting in low overall flexibility and numerous inconveniences.

[0004] Therefore, this utility model provides a dual-fluid atomizing spray gun. Utility Model Content
