The utility model discloses a laminate arrangement effectively protects the catalyst layer, effectively utilizes spatial layout, and simple structure is directly perceived, simple to operate, economic environmental protection.
Description
Technical field
The utility model relates to a kind of deduster denitrification apparatus, is applied to boiler smoke and administers, be specifically related to a kind of V-arrangement pipeline SCR denitration device.
Background technology
In boiler of power plant denitration engineering, widely use SCR(selective catalytic reduction method) denitrification apparatus, with ammoniacal liquor or urea liquid for denitrification reducing agent, adopt spray pattern to enter catalyst layer and mix with flue gas, nitrogen oxides reduction.Catalyst layer is the core component of SCR; Catalyst is formed primarily of metal oxide, is worth high, and in traditional SCR device is arranged, catalyst layer is generally layer 2-3, easily stifled grey between layers, causes catalyst activity to reduce, combustible dust also may be caused to burn, reduce catalyst activity further; In addition, traditional arrangement method is not easy to overhaul catalyst layer.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of V-arrangement pipeline SCR denitration device, carries out available protecting, effectively utilize space layout by layered arrangement to catalyst layer, structure simple, intuitive, easy for installation, economic environmental protection.
The technical scheme that the utility model technical solution problem adopts is: a kind of V-arrangement pipeline SCR denitration device, comprise air inlet, flue gas pipeline, denitration region pipeline, reducing agent pipeline and gas outlet, described air inlet is connected with boiler, described gas outlet is connected with deduster, described denitration region pipeline is V-shaped, arranged apart in described denitration region pipeline have catalyst layer I and catalyst layer II, described catalyst layer I and catalyst layer II mate respectively and are provided with one group of nozzle I and one group of nozzle II, and described reducing agent pipeline arranges two-way and is connected with nozzle I and nozzle II respectively.
As further improvement, described V-arrangement denitration region BOP is provided with access hole.
The utility model is overall or be locally connected with boiler DCS, and controls reducing agent emitted dose in real time by nitrogen oxide.
The beneficial effects of the utility model: arrange two catalyst layers by layered arrangement, carry out available protecting to catalyst layer, and every layer of catalyst layer corresponding one group of nozzle respectively, effectively reduces the catalysqt deactivation that dust reason causes; Overall Automatic Control, structure simple, intuitive, high, easy for installation, the economic environmental protection of space availability ratio.There is provided the access hole of catalyst layer, for clearing up flying dust and catalyst maintenance simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Below in conjunction with accompanying drawing, the utility model is described further.
Detailed description of the invention
As shown in Figure 1, a kind of V-arrangement pipeline SCR denitration device, comprise air inlet, flue gas pipeline 1, denitration region pipeline, reducing agent pipeline 4 and gas outlet, described air inlet is connected with boiler, described gas outlet is connected with deduster, described denitration region pipeline is V-shaped, arranged apart in described denitration region pipeline have catalyst layer I 3 and catalyst layer II 6, catalyst layer I 3 and catalyst layer II 6 mate respectively and are provided with three nozzle I 2 and three nozzle II 5,, described reducing agent pipeline 4 arranges two-way and is connected with nozzle I 2 and nozzle II 5 respectively.Access hole 7 is provided with at V-arrangement denitration region BOP.
