The cutting fluid is largely heated and evaporated to enable the total hydrocarbon content in the air of a machining workshop to be much larger than an oil mist test value, but medical research proves that the harm of oil vapor and large-particle liquid drops to the lung of a human body is relatively small, the oil mist existing in the oil vapor form is inhaled into the lung and then exhaled, and the particle oil drops with the particle size of more than 10 mu m cannot enter the lung through a nasal cavity and a bronchus; only the oil mist particles which exist in the form of liquid drops and have the diameter of less than 5 mu m can smoothly reach alveoli and deposit in lungs, which can cause benign respiratory system diseases (including asthma, pneumonia and the like), and meanwhile, toxic and harmful substances and peculiar smell generated by the thermal decomposition of the oil mist, such as acrolein, benzopyrene, cycloarene and the like, can cause great harm to bodies.

Most of traditional oil mist treatment equipment adopts an electrostatic oil mist removing method or a method combining filtering and electrostatic oil mist removing, but the method can only remove oil mist droplets with large and small particles in oil mist waste gas, but cannot remove organic gas with peculiar smell and toxic and harmful in the oil mist waste gas. Therefore, a purifying apparatus for treating the oil mist exhaust gas having the odor is required.
