Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrostatic precipitator technology, and in particular to an electrostatic precipitator cathode frame hanger. Background Technology
[0002] Electrostatic precipitators (ESPs) use high-voltage electrostatic purification to capture mist droplets or dust in exhaust gas. Their working principle is that after the dust-laden gas enters the electric field uniformly, a corona phenomenon occurs near the corona electrode, ionizing the gas. The ionized gas contains a large number of electrons and ions, which combine with the mist droplets (dust) entering the electric field to form charged particles. Under the influence of the electric field, these charged particles accumulate at the anode and cathode of the ESP, and then slide down under the action of rapping and gravity, exiting through the drain port (ash removal device). The purified gas then meets the standards and is discharged into the atmosphere.
[0003] Compared to other gas purification devices, electrostatic precipitators (ESPs) are widely used in industries such as non-ferrous metal smelting, sulfuric acid, and titanium dioxide production due to their advantages such as high demisting rate, stable performance, and low pressure drop. They are a key piece of equipment in flue gas purification processes. However, due to various reasons, ESPs still have many problems, especially the cathode frame hangers. The cathode frame hangers are an important component of ESPs, typically 4-9 meters in length. Currently, the main cathode frame hangers on the market are cylindrical and spiral cathode frame hangers. Their disadvantages include poor strength, easy breakage, few discharge points, poor corrosion resistance, difficulty in installation, and unsatisfactory demisting effect. Cylindrical cathode frame hangers have the characteristics of high electric field breakdown voltage and uniform discharge; however, due to the few discharge points and poor corrosion resistance, they suffer from unsatisfactory demisting effect in practical use.
[0004] Spiral cathode frame hangers have the characteristics of uniform discharge, high electric field breakdown voltage, and convenient installation. However, ordinary spiral cathode frames are essentially tension springs with very small or zero pitch. During installation, they need to be stretched to a very large pitch, exceeding the yield limit of the spring material, which can easily lead to plastic deformation and breakage. Utility Model Content

[0026] This application provides an electrostatic precipitator cathode frame hanger, effectively solving the problem that ordinary spiral cathode frames are essentially tension springs with very small or zero pitch. During installation, they need to be stretched to a very large pitch, exceeding the yield limit of the spring material, which easily leads to plastic deformation and breakage.
