Description
Technical field
The utility model relates to the wet electrical dust precipitator airflow uniform distribution type flow straightening grid for industrial smoke dedusting processes except mist.
Background technology
In the industry such as thermoelectricity, iron and steel, wet electrical dust precipitator, as the end treating plant of flue gas purification system, removes mist process for the flue gas before discharge carries out last degree of depth dedusting, to guarantee industrial smoke minimum discharge. But high speed flue gas is uneven at the air flow method of the inlet section of wet electrical dust precipitator, air-flow enters often there is eddy current or strong turbulent flow phenomenon in electric precipitator, the too high region of flow velocity must efficiency of dust collection low, thus the efficiency of dust collection causing wet electrical dust precipitator total reduces; On the other hand, angle is there is between air flow line and the plate that gathers dust, cathode rays, flexibility is gathered dust plate and the fracture constantly washing away the damage that can cause the plate that gathers dust and pole line of cathode rays or coming off of fastening piece by air-flow, affects safe, stable, the reliability service of wet electrical dust precipitator.
Summary of the invention
The purpose of this utility model is to provide a kind of wet electrical dust precipitator airflow uniform distribution type flow straightening grid, solve the problem that the distribution of wet electrical dust precipitator internal gas flow is uneven, to improve the efficiency of dust collection of wet electrical dust precipitator, it is achieved safe, stable, the reliability service of wet electrical dust precipitator.
Wet electrical dust precipitator airflow uniform distribution type flow straightening grid is made up of grid component and framework beam, and described framework beam comprises an outside framework and some crossbeams, and outside framework is fixedly connected with wet electrical dust precipitator inwall, and described grid component is configured on framework beam; Grid component is made up of multiple �� template that is parallel and that be spaced and multiple web plates crossing in length and breadth with it, each �� template by being located at the multiple groove grafting corresponding to each crossbeam of framework beam on the downside of its two perpendicular plate, and by be located at its two erect plate two ends breach respectively two opposite side with outside framework plug.
The described grid component being configured on framework beam can be combined by multistage.
The air-flow entered in wet electrical dust precipitator can be carried out guiding with uniform by this airflow uniform distribution type flow straightening grid, can avoid diffusing, reduces eddy current and strong turbulent flow phenomenon generation; Ensure wet electrical dust precipitator energy safety, stable, reliability service, and easy for installation, not easily amass ash, it be out of shape and blocking, it is not necessary to rinse.

In figure, 1 airflow uniform distribution type flow straightening grid, 2 outside frameworks, 3 crossbeams, 4 �� templates, 5 web plates, 6 wet electrical dust precipitators, 7 electrode assemblies.
Embodiment
As shown in Figure 1, the top of wet electrical dust precipitator 6 is provided with airflow uniform distribution type flow straightening grid 1, and middle part is provided with electrode assemblie 7. Flue gas enters wet electrical dust precipitator 6 from the direction of arrow, by the uniform stream after airflow uniform distribution type flow straightening grid 1 rectification stable flow through electrode assemblie 7, water smoke in flue gas and grit are by electrostatic adsorption and be gathered into the separated removing of ash bucket bottom bigger droplets fall to wet electrical dust precipitator 6, and flue is then discharged from the outlet of wet electrical dust precipitator 6 (passing through chimney).
Such as Fig. 2, airflow uniform distribution type flow straightening grid 1 is made up of grid component and framework beam, and framework beam comprises outside framework 2 and some crossbeams 3, and is fixed on as on the inwall of the wet electrical dust precipitator 6 of Fig. 1 with outside framework 2; Grid component is formed by connecting (see Fig. 3) by some �� templates 4 that are parallel and that be spaced and multiple web plate 5 are crossing in length and breadth; Grid component is placed on said frame beam i.e. airflow uniform distribution type flow straightening grid shown in composition diagram 2, grid component can whole section be configured on framework beam, it is possible to by two sections or more the less specification grid component combining and configuring of section. The position relation of �� template 4 and web plate 5 is as shown in Figure 4, as seen from Figure 4, the cross section shape of each �� template 4 is in " �� " type, it bonds by horizontal top plates hard with two, and each web plate 5 is positioned on the top board of �� template 4 and bonding with the top board of each �� template 4 and become grill unit (see Fig. 3 and Fig. 4). The height of leveling board width in �� template 4, plate spacing and perpendicular plate all can be optimized design according to concrete Field Flow Numerical Simulation.
Fig. 5 is the C-C sectional view of Fig. 2, figure represents the mode of connection of �� template 4 with framework beam, label 4 represents a perpendicular plate, the downside (namely illustrating the left side of �� template 4) of this perpendicular plate is provided with multiple groove, the two ends of perpendicular plate are respectively provided with a breach, grid component is connected with the corresponding grafting of multiple groove of each �� template 4 and each crossbeam 3 of framework beam, the breach at two ends respectively two opposite side grafting with outside framework 2 fix, the top board (namely illustrating the right side of �� template 4) of �� template 4 intersects vertically with it bonding by web plate 5.
This airflow uniform distribution type flow straightening grid adopts corrosion-resistant FRPP(polypropylene and the mixture of glass wool cloth) material makes. Between each parts, available polyethylene resin bonding is connected.
