Abstract
The utility model discloses a distribution of air flow device, including upper portion grid guide plate, the porous flat board in lower part, lower part grid guide plate, upper portion grid guide plate, the porous flat board in lower part, lower part grid guide plate from the top down set gradually in the lateral wall of air inlet, connect through the spliced pole between upper portion grid guide plate, the porous flat board in lower part, the downside of the porous flat board in lower part sets up lower part grid guide plate. The utility model discloses an upper portion grid board carries on a water conservancy diversion diffusion to the flue gas of entering air inlet, make it basically evenly to be full of whole air inlet, realize air current macroscopic view equipartition, it finely tunes uneven the locating of local air current to recycle lower part grid guide plate, then the air current that has flow equalized basically passes through the porous flat board in lower part, reach best flow field with final behind the gas flow uniform distribute through lower part grid board once more, realize the regulation and control of air current microcosmic, the porous flat board in lower part guarantees through different percent openings that the air current is balanced, the flue gas distribution of air flow coefficient much lower than 0.2 of process.
Description
Technical field
The utility model belongs to air and administers minimum discharge technical field, is specifically related to a kind of airflow uniform distribution device.
Background technology
Conventional airflow uniform distribution plate adopts perforated plate structure, and play macro readjustment of direction effect to the uniform of air-flow, this structure is applicable to dry electric precipitation device, and respond well.The cellular wet electrical dust precipitator of dirt sharp weapon is administered for near-zero release, the uniform requirement of relatively narrow and small, intensive gas free air space to air-flow is very high, affect efficiency of dust collection principal element, so simple perforated plate construction is no longer applicable to wet electrical dust precipitator.
Utility model content
In view of this, main purpose of the present utility model is to provide a kind of airflow uniform distribution device.
For achieving the above object, the technical solution of the utility model is achieved in that
The utility model embodiment provides a kind of airflow uniform distribution device, this device comprises top grid deflector, lower porous flat board, bottom grid deflector, described top grid deflector, lower porous are dull and stereotyped, bottom grid deflector is successively set in the sidewall of air inlet from top to bottom, connected by joint pin between described top grid deflector, lower porous flat board, the downside of described lower porous flat board arranges bottom grid deflector.
In such scheme, described top grid deflector is well word structure, is overlapped form by the plate that some pieces of angles are different.
In such scheme, described lower porous flat board is flat circle orifice plate.
In such scheme, described bottom grid deflector is well word structure, is overlapped form by the plate that some pieces of angles are different.
Compared with prior art, the beneficial effects of the utility model:
1, upper grid plate of the present utility model carries out a water conservancy diversion diffusion the flue gas entering air inlet, makes it substantially to be full of whole air inlet, makes air-flow macroscopical.
2, the flue gas after upper grid plate water conservancy diversion is carried out secondary water conservancy diversion by bottom of the present utility model deflector, is to adjust the secondary of air-flow.
3, uniform stream is distributed by different percent openings by lower porous flat board of the present utility model again, reaches best flow field.
Accompanying drawing explanation
Fig. 1 provides a kind of structural representation of airflow uniform distribution device for the utility model embodiment.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The utility model embodiment provides a kind of airflow uniform distribution device, as shown in Figure 1, this device comprises top grid deflector 1, bottom grid deflector 2, lower porous flat board 3, described top grid deflector 1, lower porous flat board 2, bottom grid deflector 3 are successively set in the sidewall of air inlet 4 from top to bottom, connected by joint pin 5 between described top grid deflector 1, lower porous flat board 2, the downside of described lower porous flat board 2 arranges bottom grid deflector 3.
According to actual airflow analog case, the upside of described lower porous flat board 2 also can arrange a part of bottom grid deflector 3 at an upper portion thereof.
Described top grid deflector 1 is well word structure, and overlapped by the plate that some pieces of angles are different and form, all plate hights and angle draw by CFD computer simulation.
Described lower porous dull and stereotyped 2 is flat circle orifice plate, and percent opening and perforate size are drawn by CFD computer simulation.
Described bottom grid deflector 3 is well word structure, and overlapped by the plate that some pieces of angles are different and form, all plate hights and angle draw by CFD computer simulation.
The course of work of the present utility model:
Described upper grid plate 1 carries out a water conservancy diversion diffusion the flue gas entering air inlet 4, make it substantially evenly to be full of whole air inlet 4, realize air-flow macroscopic view uniform, the uneven place of bottom grid deflector 3 pairs of local air flows on dull and stereotyped 2 tops of recycling lower porous finely tunes, then the air-flow of current-sharing is substantially by lower porous flat board 2, eventually pass through bottom grid deflector 3 after again being distributed by uniform stream and reach best flow field, realize the regulation and control of air-flow microcosmic, by different percent openings, described lower porous dull and stereotyped 2 ensures that air-flow is balanced, the uniform coefficient of flue gas stream after the utility model is far smaller than 0.2.
The above, be only preferred embodiment of the present utility model, is not intended to limit protection domain of the present utility model.
