Description
Technical Field
[0001] The utility model belongs to the technical field of oil fume purification equipment, and in particular relates to a wet electrostatic purifier with an external insulator and independent air intake. Background Art
[0002] A large amount of oil smoke is emitted in industrial production, the catering industry, and boiler combustion. Its characteristics are high temperature, large amount of smoke, and high concentration. It not only causes serious pollution to the environment, but more importantly, it has serious consequences for the health of the surrounding people. For this reason, oil fume purifiers are installed in places with large amounts of oil fume emissions to reduce emissions. Currently, commonly used oil fume purifiers mainly use electrostatic generators to generate high-voltage static electricity in the electric field generation area, thereby enhancing the electric field force, thereby adsorbing and purifying the oil fume particles passing through the electric field area of the electrostatic generator. This electrostatic purification equipment has a simple structure, low cost, and is easy to use. However, the electrostatic generator is prone to depositing a large amount of stains during the operation of the oil fume particles. If the stains in the oil fume purifier and the electrostatic generator are not cleaned in time, the purification effect and service life of the oil fume purifier and the electrostatic generator will be affected. However, most oil fume purifiers and electrostatic generators are difficult to disassemble and install, and are inconvenient to clean. Cleaning is not only time-consuming and labor-intensive, but also affects the long-term use effect of the oil fume purifier equipment. Utility Model Content
