Abstract

The invention provides an oil mist measuring method and relates to the environment monitoring field. A constant speed sampling method is employed to collect an oil mist sample, and then the oil smoke content is measured through an infrared spectrophotometry. The method is widely suitable for measurement of steel rolling industry oil mist emission concentrations. The method has advantages of simple operation, easy popularization, low detect limit, high sensitivity, wide measurement scope, high accuracy and the like.

Description

technical field [0001] The invention relates to the field of environmental monitoring, in particular to a method for measuring the emission concentration of oil mist in the steel rolling industry. Background technique [0002] Metal processing lubricants in the steel rolling industry are subjected to pump circulation, spraying and fierce impact with high-speed rotating workpieces during use, and are broken up by them, forming fine droplets floating in the working environment, accompanied by the surface of high-temperature components and the entire cutting space. The high temperature evaporates to form oil mist. The formed oil mist is a uniform dispersion system formed by solid particles, liquid particles, and liquid and solid particles suspended in a gas medium, that is, floating in the air in the workplace in the form of aerosols. Studies have shown that most of the oil mist particles floating in the workshop have a diameter of about 1 μm. These small oil mist particles a...
