Problems solved by technology

These oil mist particles will be deposited in the ventilation pipes, inside the purification equipment and on various walls in the workshop during the propagation process. The oil mist particles deposited to a certain extent over time will seriously affect the performance and service life of the equipment; the deposited on the walls of the ventilation system Oil mist particles will also volatilize with higher air velocity to form secondary pollutants

Abstract

The invention discloses a measurement cabin capable of rapidly and accurately measuring deposition characteristic of a wall surface of a device comprising oil mist flow in real time. The system mainlycomprises an oil mist diffusion system, a main pipeline system, a mixed box, a monitoring system and an experiment segment system, wherein an air compressor is used for generating gas-state oil mistparticles by compressing liquid-state oil in an oil mist generator and injecting the gas-state oil mist particles into a main pipeline from the oil mist generator, the gas-state oil mist particles enter the experiment segment system through the main pipeline system, and a time change curve and maximum value of oil mist deposition quantity of the wall surface can be obtained by analyzing data recorded by an optical particle grain spectrometer of the monitoring system. By the system, the oil mist settlement rate of a target device can be conveniently, rapidly and accurately measured, and the deposition rule of the oil mist on the target device can be obtained.

Description

technical field [0001] The invention belongs to the field of air quality and pollutant transmission in closed spaces, and in particular relates to a real-time measurement cabin for monitoring the oil mist deposition characteristics on the wall surface. Background technique [0002] In industrial workshops, cutting fluids containing mineral oils and anti-rust additives are widely used for cooling and lubricating parts. These cutting fluids will continue to produce pollutants such as oil mist particles after undergoing intense collisions with high-speed rotating tools and high-temperature evaporation. These oil mist particles will be deposited in the ventilation pipes, inside the purification equipment and on various walls in the workshop during the propagation process. The oil mist particles deposited to a certain extent over time will seriously affect the performance and service life of the equipment; the deposited on the walls of the ventilation system Oil mist particles w...
