Description

Technical Field

[0001] The invention relates to an electrostatic purification device. Background Art

[0002] Various electrostatic purification devices are disclosed in the prior art, such as the "Electrostatic Purification Device for Oil Fumes" disclosed in Patent No. ZL 02257040.3 (Authorization Announcement No. CN2586536 Y), which includes a power supply, a box, an electrode plate, and an oil collecting basin. The box is a closed structure, and is provided with an air inlet and an air outlet connected to the smoke exhaust pipe; the electrode plate includes a positive plate and a negative plate, which are vertically arranged in the box and alternately arranged parallel to each other at an appropriate distance; the oil collecting basin is arranged below the electrode plate; the power supply provides DC high voltage electricity to the electrode plate. When the device is working, an electrostatic field is formed on the oil and gas channel, and under the action of the electrostatic field, the tiny oil droplets entering the electrostatic field are adsorbed to the electrode surface. Although the electrostatic purification device has the advantages of low energy consumption, low noise, and no secondary pollution, it adopts a simple staggered structure of positive and negative plates. The positive and negative plates are not staggered with each other. The positive and negative plates are installed on the same support frame. When oil accumulates on the support frame, the surface is prone to creep electricity, and the current is concentrated on the surface discharge, resulting in a reduction in the number of moving charged particles between the plates, making it easy for the positive and negative plates to conduct, thereby rendering the electrostatic purification device ineffective. For example, there is an electrostatic purification device in which insulating brackets are installed on two opposite sides of the outer support frame, and springs are installed on the inner side of the insulating bracket. The two ends of the electrode wire are respectively installed on the springs on the corresponding sides. This wire winding method is relatively conventional. Moreover, since multiple electrode wires need to be installed, it is easy to touch the installed electrode wires during wire winding, which brings certain inconveniences to the installation of the electrode wires. In summary, further improvements need to be made to the existing electrostatic purification devices. Summary of the invention
