AI Technical Summary

Technical Problem

Existing SCR denitrification reactors have limitations in modular assembly, making it difficult to flexibly adjust their scale and structure according to different industrial scenarios. They cannot adapt to frequently changing production needs and complex operating conditions, and are prone to clogging in high-concentration dust environments, increasing equipment maintenance costs.

Method used

The modularly designed low-temperature SCR denitrification reactor kit achieves flexible reactor combination and dust treatment through the series connection of reaction modules, ammonia delivery pipes and ash collection bins. Combined with honeycomb ceramic carriers and vanadium-based, tungsten-based or manganese-based catalysts, it ensures uniform mixing of ammonia and flue gas and efficient catalytic reaction.

Benefits of technology

It improves the reactor's flexibility and denitrification efficiency, reduces equipment installation and maintenance costs, and ensures stable operation and efficient dust treatment under complex working conditions.

Abstract

The utility model relates to SCR denitration reaction equipment technical field, concretely for modularization low temperature SCR denitration reactor suite, including a plurality of reaction module, reaction module between sequentially series connection forms a reactor group, the upper portion of reactor group is provided with ammonia gas delivery pipe, ammonia gas delivery pipe passes through a plurality of shunt pipe and delivers ammonia gas to every reaction module, and the bottom of every reaction module is installed for collecting reaction dust's dust collecting bin, and reaction module includes for ammonia gas and ammonia gas mixed mixing bin and for mixed gas carries out catalytic reaction's reaction bin. The modularization low temperature SCR denitration reactor suite, from the modularization design, multiple reaction modules sequentially series connection constitutes reactor group, and this kind of modularization structure greatly promoted the flexibility of equipment application. Enterprise can increase and decrease reaction module number according to actual flue gas processing capacity, working condition changes, and conveniently, quickly adjusts reactor scale, effectively solved the problem that prior art cannot flexibly cope with complex working condition.
