Oil mist purification filter element

Abstract

The invention discloses a filter element, in particular to an oil mist purification filter element which comprises a gas-liquid filter screen and an outer frame for fixing and unfolding a laminated gas-liquid filter screen which is folded, wherein the gas-liquid filter screen is formed by weaving a steel wire with the diameter of 0.2 layer-05mm and a PP (polypropylene) fiber with the diameter of 1.0 layer-2.0mm or a glass fiber, the steel wire and the PP fiber or the glass fiber are wound, meshes of two specifications are distributed on the gas-liquid filter screen at intervals, the first mesh takes on a rectangle with the length L3 of 4.5mm-6mm and the width W1 of 4mm-5.5mm, and the second mesh takes on a rectangle with the length L3 of 6mm-6.5mm and the width W3 of 4mm-5.5mm. According to the filter element, the technical defect that the existing gas-liquid filter screen is poor in filter quality or low in filter efficiency is overcome, the filter element is mainly applied to an oil mist filter system, and has the advantages that the filtration flux is large and the accuracy is high, and the like.

Description

technical field [0001] The invention relates to a filter element, in particular to an oil mist purification filter element. Background technique [0002] During the machining process, the use of metal cutting fluid will generate a large amount of oil mist. The generation of these metal cutting fluid oil mist will bring a series of problems: [0003] 1. First of all, the fire hazard in the workshop increases, and the possibility of workers slipping on the floor with oil mist increases; [0004] 2. Secondly, long-term exposure of workers to metal cutting fluid oil mist will lead to a significant increase in the incidence of respiratory diseases, allergic skin diseases and malignant tumors, and may cause genetic effects; [0005] 3. Finally, another major hazard of metal cutting fluid oil mist is its carcinogenicity. The carcinogenicity of metal cutting fluid mainly depends on the concentration of its additives, contamination and use conditions. There are no studies on the c...

The wire mesh made of steel wire is not easy to adhere to the oil mist particles on the surface of the steel wire, which reduces the possibility of oil mist particles colliding with each other and electrostatic attraction during use, so that the oil mist filtering effect is poor; the wire mesh made of fiber wire, Due to the poor rigidity of the fiber filaments, the fiber mesh is easily deformed during use, which affects the overall oil mist filtration flux
