Abstract
The utility model relates to a flue gas denitration flue guide plate device, including installing the guide plate that a plurality of in the flue bend was parallel to each other, the guide plate is the arc, and the both ends of guide plate are equipped with support piece, be equipped with interior pole in the flue bend, the tip of pole including support piece is fixed. The utility model discloses a flue gas denitration flue guide plate device sets up the guide plate in the flue bend before flue gas denitration gets into the gas distribution ware, avoid the flue gas in the flue burble, agitate, influence the degree of consistency of mixture, it is even to make the flue gas velocity who gets into the SCR reactor distribute, the even running of promotion flue gas denitration reactor system.
Description
Technical field
The utility model relates to a kind of denitrating flue gas flue deflector device, for improving the air velocity distribution of fire coal boiler fume denitrating system air inlet flue, belongs to gas denitrifying technology field.
Background technology
Nitrogen oxide (NO
x) be one of main atmosphere pollution, be also the major reason of forming region fine particles pollution and gray haze, Thermal Power Generation Industry nitrogen oxide emission is huge, in the urgent need to controlling.Along with " fossil-fuel power plant atmospheric pollutant emission standard " (GB13223-2011) starts to perform, medium-and-large-sized coal-burning power plant basic need adopts SCR denitration just can reach the emission request of nitrogen oxide.But from SCR denitration technology generally most SCR gas denitrifying technology still digest and assimilate and the Preliminary Applications stage, company technically carries out upgrading optimization in traditional SCR denitration, improve the stability of denitration efficiency and system, meet coal-fired plant flue gas denitration requirement.
Based on this, the utility model is proposed.
Utility model content
Stable flue gas stream is at the uniform velocity needed for SCR denitration system gas approach, the purpose of this utility model is to provide a kind of denitrating flue gas flue deflector device, flue gas can be avoided in flue, to produce eddy current, agitate, keep flue gas flow field to stablize, improve follow-up ammonia and spray into the rear uniformity.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of denitrating flue gas flue deflector device, comprise and be arranged on several in flue bend deflectors of being parallel to each other, described deflector is arc, and the two ends of deflector are provided with support member, be provided with interior bar in described flue bend, described support member is fixed on the end of interior bar.
Described support member is made up of orthogonal two poles.
Described deflector is positioned at the front of flue gas distributor.
The beneficial effects of the utility model are as follows:
Denitrating flue gas flue deflector device of the present utility model, in flue bend before denitrating flue gas enters flue gas distributor, deflector is set, flue gas is avoided in flue, to produce eddy current, agitate, affect the uniformity of mixture, the flue gas flow rate entering SCR reactor can be made to be evenly distributed, to promote the even running of flue gas denitration reactor system.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation that the utility model is arranged in flue bend;
Fig. 3 is the utility model Zhong Neigan district schematic diagram;
Wherein, 1 be flue bend, 2 be deflector, 3 be support member, 4 for interior bar.
Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is further described, but protection domain of the present utility model is not limited to this.
As Figure 1-3, denitrating flue gas flue deflector device of the present utility model, comprise and be arranged on several in flue bend 1 deflectors 2 of being parallel to each other, deflector 2 is arc, and the two ends of deflector 2 are provided with support member 3, support member 3 is made up of orthogonal cross bar and montant, is provided with interior bar 4 in flue bend 1, and support member 3 is fixed on the end of interior bar 4.
Denitrating flue gas flue deflector device of the present utility model, for the even flow field of the flue gas of flue before flue gas SCR denitration system, in flue bend 1 before denitrating flue gas enters flue gas distributor, arc deflector 2 is set, flue gas can be avoided in flue, to produce eddy current, agitate, keep flue gas flow field to stablize, affect the uniformity of mixture, the flue gas flow rate entering SCR reactor can be made to be evenly distributed, improve follow-up ammonia and spray into the rear uniformity
Promote the even running of flue gas denitration reactor system, improve denitrating system stability.
Above-described embodiment only illustrates inventive concept of the present utility model for explaining, but not the restriction to the utility model rights protection, all changes utilizing this design the utility model to be carried out to unsubstantiality, all should fall into protection domain of the present utility model.
