Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of air purification, in particular to an electrostatic adsorption type double-layer high-speed filter. Background Art
[0002] Air filters, a device that uses porous filter material to capture dust from gas-solid two-phase flows, are primarily used to purify air to ensure cleanroom process requirements and maintain air cleanliness within general air-conditioned rooms. Air filters are particularly important in environments requiring high cleanliness, such as the electronics and pharmaceutical industries, and hospitals. They effectively remove dust, microorganisms, smoke, and other particulate matter from the air.
[0003] Electrostatic precipitation is a dust removal technology that uses electrostatic forces to separate particles from airflow. Dust-laden gas passes through a high-voltage electrostatic field. Dust particles combine with negative ions, becoming negatively charged. These particles then discharge toward the anode surface, where they are deposited. This method is used in industries such as metallurgy and chemistry to purify gases or recover useful dust particles. In a strong electric field, air molecules are ionized into positive ions and electrons. As the electrons travel toward the anode, they encounter dust particles, causing them to become negatively charged and attract to the anode, where they are collected.
[0004] Existing electrostatic adsorption air filtering equipment has poor filtering effect and is inconvenient to replace and maintain. Therefore, there is a need for an electrostatic adsorption double-layer high-speed filter that can improve the filtering effect. Utility Model Content
