The invention discloses a structural
layout for an
ammonia uniform distribution device for
flue gas denitration, wherein the structural
layout comprises
ammonia gas spray nozzles,
ammonia gas auxiliary spray nozzles,
ammonia gas spray pipes, installation casing pipes, ammonia spraying branched pipes, anti-blocking filters, manual regulation valves, an ammonia spraying mother
pipe, an
ammonia gas pressure meter, and an
ammonia gas temperature meter; the structural
layout is characterized in that a fixed modularization layout is adopted, with a combination structure of the ammonia gas spray nozzles, the ammonia gas auxiliary spray nozzles, the ammonia gas spray pipes, the installation casing pipes, the ammonia spraying branched pipes, the ammonia spraying mother
pipe, the manual regulation valves, the anti-blocking filters and the like, the ammonia spraying uniformity in a
flue is achieved, the coverage area of ammonia spraying is expanded, and the
spray nozzle blocking probability is decreased, so that the denitration adequacy and denitration efficiency of
flue gas are improved, the ammonia
escape rate is reduced,
environmental protection is facilitated, ammonia spraying is uniform, the coverage area is wide, the spray nozzles cannot be blocked, the structure is simple, the service life is long, the gas flow quantity is controllable and adjustable, and the whole and parts are convenient to disassemble, check, maintain and install. The shortcomings of the prior art are overcome.
