Problems solved by technology

However, because the dust particles in the back electric field are fine and sticky, it is difficult to remove the fine dust from the anode plate by single top rapping or side rapping, resulting in back corona in the back electric field
For this reason, it is usually overcome by increasing the top or side rapping force. However, increasing the top or side rapping force can only shake the upper part of the anode plate (top rapping) or the lower part of the anode plate (side rapping). rapping) is relatively clean, and it is difficult to remove the fine dust on the entire anode plate

Abstract

The invention discloses an electric precipitator for removing ash through isolated vibration and striking. The electric precipitator comprises anode plates (1), cathode wires (2), anode plate vibration-striking devices and isolation pore plates, wherein the isolation pore plates are arranged at the rear parts of the anode plates (1) and respectively correspond to airflow channels between two adjacent pore plates (1), and through holes are formed in the isolation pore plates; the through holes are in an opening state and a closed state and are used for guiding through the corresponding airflow channels in the opening state and blocking the corresponding airflow channels in the closed state. According to the electric precipitator, the back corona and re-entrainment of a rear electric field can be effectively prevented, so that the dust removing efficiency is effectively increased; the electric precipitator can stably work in a low emission manner for a long time. The invention further discloses an isolcated vibration-striking time schedule control method applied to the electric precipitator.

Description

technical field [0001] The invention relates to the technical field of dust removal equipment, in particular to an electric dust collector which utilizes the principle of mutual attraction of positive and negative charges for dust removal. The invention also relates to a rapping control method of the electrostatic precipitator. Background technique [0002] Electrostatic precipitator is a commonly used flue gas purification equipment, which can remove the particulate smoke and dust in the exhaust gas of coal-fired or oil-fired boilers, thereby greatly reducing the amount of smoke and dust discharged into the atmosphere, which is to improve environmental pollution and improve The important environmental protection equipment for air quality has the advantages of high efficiency, convenient operation and management, and strong adaptability. It is widely used in various flue gas treatment occasions in the industrial field. [0003] The working principle of the electrostatic pre...
