Problems solved by technology
For the air inlet variable diameter pipe of the central air intake, the most widely used device is the uniform distribution device of the porous plate, such as figure 1 As shown, several airflow openings 102' of the same size are evenly arranged on the airflow distribution plate 101' of the device. Since the gas structure is too simple, although it is easy to manufacture and produce, in the actual use process, for some central inlets When the pipeline is very irregular, the effect of flow sharing is very bad

Embodiment Construction
[0015] based on the following figure 2 , illustrating a preferred embodiment of the present invention.
[0016] Such as figure 2 As shown, it is a structural schematic diagram provided by the present invention; it includes 2 airflow distribution plates 101 and 102 arranged at a certain distance, and several airflow openings distributed at a certain position are respectively arranged on the 2 airflow distribution plates 101 and 102. hole 103;
[0017] In the lee of the airflow opening 103 of the side wall area part of the air distribution plate 101 at the front end of the diffuser, a deflection guide baffle 104 is arranged, which is inclined along the direction of the diffusion angle; the length of the deflection guide baffle 104 is along the Changes in the height and width of the pipe;
[0018] The deflection deflector baffle 104 can effectively guide the airflow to diffuse and distribute evenly along the diffuser pipe. Since each deflection deflector baffle 104 has diffe...

The invention discloses an airflow distribution device in a large airflow pipeline system. The airflow distribution device comprises a plurality of airflow distribution boards arranged at certain intervals. The airflow distribution device is characterized in that a plurality of airflow open holes are distributed in the airflow distribution boards at certain positions in a line-strip-block combination mode; deflection flow guiding baffles are arranged at the position, the sheltered sides of the airflow holes, of the wall region portions of the airflow distribution boards; perpendicular flow blocking baffles are arranged at the positions, the sheltered sides of the airflow holes, of the central region portions of the airflow distribution boards, and the airflow holes in the adjacent airflow distribution boards are distributed in a staggered mode. According to the airflow distribution device, airflow uniform diffusion distribution of a reducing pipe is effectively achieved, the airflow outlet speed of the reducing pipe section becomes uniform, the purification efficiency can be improved, and working conditions of purification equipment can be improved.
Description
technical field [0001] The invention relates to an airflow distribution device, in particular to an airflow uniform distribution device for a variable-diameter pipe section in a large-scale airflow pipeline system. Background technique [0002] The unevenness of the velocity distribution on the working section of the electrostatic precipitator will affect the purification efficiency of the smoke and dust. Generally, the more uneven the velocity distribution, the more the purification efficiency will drop. [0003] The introduction of airflow into electrostatic precipitator or bag filter usually transitions from a ventilation pipe with a small section to a working room with a large section. If necessary measures are not taken, the uneven distribution of airflow will be affected. [0004] The distribution of the inlet airflow of large electrostatic precipitators and bag filters has a great influence on the purification performance of the equipment. Under normal circumstances,...
