Abstract
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.
Description
technical field [0001] The invention relates to the technical field of chemical technology for flue denitrification, in particular to a structural layout method of an ammonia uniform distribution device for flue denitrification. Background technique [0002] There are many types of denitrification ammonia gas distribution devices in the prior art, but due to the characteristics of the denitrification reaction, the nozzles of the ammonia gas distribution device are easily blocked, resulting in uneven mixing of flue gas, resulting in a decrease in denitrification efficiency. [0003] The various arrangements of uniform ammonia gas in the prior art have solved some nozzle clogging problems to a certain extent and expanded the flue gas mixing effect. However, due to the need to do a lot of simulation preparation work before the arrangement, the cycle is long. And can't really avoid the generation of blocking situation. Coupled with improper arrangement, it seriously affects the...
