AI Technical Summary

Technical Problem

Existing SCR denitrification devices face challenges and high safety risks during the cleaning process, especially in narrow areas and at high altitudes. Existing sonic cleaners are ineffective in cleaning these areas, and ammonia gas combines with dust to form a ash layer, affecting the normal operation of the equipment and residents' lives.

Method used

An SCR denitrification and dust removal device was designed, including an anti-slip handle, a drive rod, a dust removal component, a telescopic component, and a water spray system. It utilizes a cylinder and a rotating shaft in conjunction with a scraper, and achieves efficient cleaning through the telescopic rod and water spray hose, reducing safety risks and improving dust removal efficiency.

Benefits of technology

It achieves efficient cleaning of dust on the inner wall of the SCR denitrification tower, reduces the safety risks to workers, improves cleaning efficiency and environmental safety, reduces dust flying, and lowers the difficulty of cleaning.

Abstract

This utility model relates to the field of SCR denitrification technology, and more particularly to an SCR denitrification dust removal device and a cement kiln tail flue gas SCR denitrification tower. It includes an anti-slip handle and a dust removal assembly, the latter comprising a cylinder end located at the top of a drive rod. Through the arrangement of the cylinder and rotating shaft, when workers need to clean dust from high areas on the inner wall of the tower, the scraper, extended by the cylinder, can effectively clean the dust from these areas. This design facilitates handheld operation, and the rotating shaft enhances the scraper's ability to effectively remove dust from different angles. Furthermore, the repeated extension of the hollow telescopic rod and cylinder effectively removes stubborn dust adsorbed onto the inner wall of the tower. Compared to existing technologies, this eliminates the need for workers to climb ladders to reach higher areas for dust removal, and the worker's position on the tower body reduces safety risks, thereby simplifying the dust removal process.
