Background technology
Nitrogen oxides not only can produce the environmental problem such as acid rain, photochemical fog, also can health be adversely affected.Therefore, the reduction of discharging of nitrogen oxides and improvement are instant problems.With NH3SCR technology (SCR) for reducing agent is current industrial maximally effective stationary source NOxRemoval methods.SCR denitration of the prior art is generally arranged in casing, and the casing arranged by multiple tier array of whole SCR denitration reactor is stacking forms, casing is supported by supporting beam, and be moved upwardly by order to avoid in casing, the flue gas of transmission is reverse from the bottom spilling of casing, the top of adjacent boxes carries out sealing by sealing plate, to stop that flue gas flows upward.But, in actual use, SCR denitration reactor is in transportation, distance between casing is susceptible to change, casing distance increases the sealing plate easily dragging out top, easily cause flue gas short circuit, cause the denitration efficiency of SCR denitration reactor to reduce and shorten the service life of SCR denitration reactor.
Summary of the invention
This utility model provides a kind of SCR denitration reactor, it is achieved improves the denitration efficiency of SCR denitration reactor and extends its service life.
This utility model provides a kind of SCR denitration reactor, including Multi-layer supporting beam, every layer of described support beam is provided with multiple denitration casing, described denitration casing is provided with SCR denitration, between adjacent two described denitration casings, top seal is set, described top seal includes ridge cover plate and two side plates, and described side plate is arranged on the dual-side of described ridge cover plate, and the bottom of two described side plates connects with the top of corresponding described denitration casing；The bottom of described denitration casing is additionally provided with deflector, and described deflector tilts extend down and shelter from described support beam.
Further, described ridge cover plate and described side plate are an overall structure.
Further, being additionally provided with lower seals between described denitration casing and described support beam, described lower seals is L-type angle steel, and described L-type angle steel is welded between described denitration casing and described support beam.
Further, the angle that described ridge cover plate is formed is 90 ° ~ 120 °.
Further, described deflector is 35 ° ~ 60 ° with the angle of horizontal direction.
nullThe SCR denitration reactor that this utility model provides，By adopting the top of adjacent two the denitration casings of ridge cover plate for sealing，Ridge cover plate is connected with denitration casing by the side plate of both sides，In transportation，Even if occurring apart from upper change between denitration casing，The power that two side plates are produced by denitration casing will be passed to ridge cover plate，Ridge coverplate stress is deformed，To meet the requirement of two denitration casing distances，Guarantee that the top of denitration casing seals reliable，Thus avoiding the phenomenon of flue gas short circuit to occur，Meanwhile，The bottom of denitration casing arranges deflector folding support beam，The stop of the air-flow beam supported of flowing in denitration casing can be avoided to cause local resistance excessive and the generation of the phenomenon of generating section flue gas residence，The catalysis " efficiency " making denitrating catalyst reduces，Realize improve SCR denitration reactor denitration efficiency and extend its service life.
