Abstract For improving the collection efficiency of electrostatic precipitator (EP) in the pigsty, MATLAB & Finite element method (FEM) is applied to calculate RNG k-ε equations, corona equation and acoustic radiation equations to analyze sound field, electric field and particle trajectory in the wire-plate EP. The results show that fine particle agglomeration can be induced, so as to promote the enlargement of fine particles and improve the capture efficiency of fine particles at acoustic node area. Moreover, the particle distribution can be controlled according to the above V-η curve in the pigsty. In addition, η initially increases, and then decreases in the range of f from 1000 Hz to 2000 Hz. Therefore, the linear variation law of V– η & SPL – η & f – η provide scientific control method for the construction of green and efficient removal technology of particulate pollutants in the piggery.

Dust Precipitator

In this paper, solar photovoltaic technology and electrostatic dust removal technology are combined to design a solar electrostatic precipitator, and its operation effect and dust removal performance are studied. Starting from optimizing the structure of the dust precipitator, the electrode structure of the dust precipitator was improved, the area of dust collector per unit volume was increased, and the dust removal efficiency was improved. By changing different working conditions, different solubility, different voltage, and different dust removal efficiency. Finally, compared the dust removal efficiency of the finned tubular and snowflake dust precipitator. The results show that the snowflake dust precipitator works stably in sunny and cloudy weather, and the dust removal effect is the highest, followed by dry powder, and the cement dust removal effect is the worst. It is determined that the change of voltage within the set range has little influence on the dust removal efficiency, and the dust concentration has a great influence on the dust removal efficiency.
