Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in detail, but this utility model is not limited to this detailed description of the invention。
This utility model provides a kind of electrostatic precipitator airflow-distribution board combination unit, and electrostatic precipitator is the common electrostatic precipitator being provided with ventilation shaft 1, air intake vent 2 and air outlet 3。Airflow-distribution board combination unit of the present utility model includes primary air stream distribution grid 4, secondary air flow distribution grid 5 and three grades of airflow-distribution boards 6。
As it is shown in figure 1, the perforate on primary air stream distribution grid 4 is evenly distributed, percent opening is 50%～70%。As in figure 2 it is shown, it is 20%～40% that secondary air flow distribution grid 5 is from top to bottom uniformly divided into the percent opening in 2-I district 7,2-II district 8 and district of 2-III district 9,2-I 7, the percent opening in 2-II district 8 is 30%～50%, and the percent opening in 2-III9 district is 40%～60%。As it is shown on figure 3, the percent opening that three grades of airflow-distribution boards 6 are from top to bottom uniformly divided into 3-I district 10,3-II district 11 and district of 3-III district 12,3-I 10 is 40%～60%, the percent opening in 3-II district 11 is 30%～50%, and the percent opening in 3-III district 12 is 20%～40%。
The primary air stream distribution grid 4 of this device is arranged in the ventilation shaft 1 before entering air intake vent 2, and secondary air flow distribution grid 5 is arranged on air intake vent 2 place, and three grades of airflow-distribution boards 6 are arranged on air outlet 3 place。Wherein, as shown in Figure 4, after disorderly air-flow primary air stream distribution grid 4 in ventilation shaft 1, air-flow can realize current-sharing。The percent opening of air intake vent 2 place secondary air flow distribution grid 5 is up-small and down-big uneven distribution, and resistance above is big, and resistance below is little, force air-flow in a large number to the diffluence of airflow-distribution board bottom, form downward-sloping air-flow, but also have a small amount of air-flow to hover up, form vortex。Air-flow is substantial amounts of flows to bottom, make to occur below electric field postmedian downward air-flow, and the percent opening of the three grades of airflow-distribution boards 6 in exit is up big and down small distribution, reducing the percent opening of the bottom, force again air-flow to move upward, in exit 3, air velocity is evenly distributed, material is thus formed good skewed gas flow, which increase air-flow and the powder dust particle time of staying in cleaner unit, increase electric field and catch the time of powder dust particle, and then improve efficiency of dust collection。When distance between primary air stream distribution grid 4 and secondary air flow distribution grid 5 is 1.5～2 times of ventilation shaft internal diameter, air flow method effect is best, and efficiency of dust collection is the highest。
