Description
Technical field
This utility model is related to a kind of scr Benitration reactor guiding device.
Background technology
Existing guiding device is the deflector by placing arc in reactor flue, and the flowing to flue gas is drawn
Lead, thus reaching the purpose making flow field be more uniformly distributed.But, in order to reach preferable water conservancy diversion effect, need the deflector laid
Number is often more, and, the hanging deflector placed in flue when designing, and there is very big being stranded in actual production process
Difficult.
Utility model content
The purpose of this utility model is to provide a kind of scr Benitration reactor guiding device, makes flowing in device for the flue gas
It is more uniformly distributed, effectively weaken the corrosion to catalyst.
For solving above-mentioned technical problem, this utility model adopts the following technical scheme that
A kind of this utility model scr Benitration reactor guiding device, including inlet flue duct, spray ammonia flue, transition flue duct, urges
Change room and exhaust pass, described catalysis interior is evenly arranged with multi-layer catalyst layer；Described inlet flue duct upper end and described spray ammonia
Flue lower end connects, and described spray ammonia flue upper end is connected with the lower end of described transition flue duct one end, the described transition flue duct other end
Lower end connect with described catalyst chamber upper end, described catalyst chamber lower end is connected with described exhaust pass upper end；Described transition flue duct
The upper surface of the other end is downward-sloping facing directly, makes the rectangular triangle in longitudinal section of the other end of described transition flue duct；Institute
State and the bar shaped block that longitudinal section is triangle is provided with the upper end inwall of transition flue duct.
Further, the inwall of described spray ammonia flue is provided with one or 2 blocks.
Further, 1 or 2 described blocks are three rhombohedreons.
Further, 1 or 2 described blocks are three curved rhombohedreons.
Further, 2 described three rhombohedreons relative and arrangements that misplace on described inlet flue duct inwall.
Compared with prior art, Advantageous Effects of the present utility model: device form and structure are simple, benefit installation；
Flowing in device for the flue gas is more uniformly distributed, and effectively weakens the corrosion to catalyst, extends catalyst life.

Specific embodiment
As shown in figure 1, a kind of scr Benitration reactor guiding device, including inlet flue duct 1, spray ammonia flue 2, transition flue duct
3rd, catalyst chamber 4 and exhaust pass 5, is evenly arranged with multi-layer catalyst layer in described catalyst chamber 4；Described inlet flue duct 1 upper end with
Described spray ammonia flue 2 lower end connection, described spray ammonia flue 2 upper end is connected with the lower end of described transition flue duct 3 one end, described transition
The lower end of flue 3 other end is connected with described catalyst chamber 4 upper end, and described catalyst chamber 4 lower end is with described exhaust pass 5 upper end even
Logical；The upper surface of described transition flue duct 3 other end is downward-sloping facing directly, so that the vertical of the other end of described transition flue duct 3 is cut
The rectangular triangle in face；The bar shaped block 6 that longitudinal section is triangle is provided with the upper end inwall of described transition flue duct 3.
As shown in Fig. 2 in another embodiment, on the inwall of spray ammonia flue 2, the form that goes to upper and lower of relative dislocation is provided with 2
Individual three curved rhombohedreons 7, effective reducing smoke flow velocity.
Device form of the present utility model and structure are simple, benefit installation.As shown in Figures 3 and 4, water conservancy diversion of the present utility model
Device makes flowing in device for the flue gas be more uniformly distributed, and effectively weakens the corrosion to catalyst layer, extends catalyst life.
Embodiment described above is only optimal way of the present utility model to be described, not to of the present utility model
Scope is defined, and on the premise of without departing from this utility model design spirit, those of ordinary skill in the art are new to this practicality
Various modifications and improvement that the technical scheme of type is made, all should fall into the protection domain of this utility model claims determination
Interior.
