When the device that measures.
Background technology
It is cooled down and is lubricated commonly using metal working fluid in mechanical processing process, which partly waves with high concentration
The generation of hair property aerosol.Worker is directly sucked in and by this kind of aerosol of skin contact, will produce dermatitis and respiratory system disease
Disease can also increase the Expectancies such as lung cancer, laryngocarcinoma studies have shown that being chronically exposed in this high concentration aerosol.Mechanical processing
Half volatile aerosol in the process is made of olesome and gaseous pollutant two parts, accurately measures this two-part concentration
It is extremely important.Common particle sampling method has filter membrane sampling, inertial impactor sampling and light scattering method.Filter membrane sampling process
Middle oil mist particles are collected on filter membrane, and the steaming of oil mist particles can be caused constantly through filter membrane by continuing the aspirated air of sampling
Hair, the concentration for eventually leading to oil mist particles are underestimated；During inertial impactor samples, oil mist particles collision is impacted in solid
The problems such as rupture, rebound can occur on plate, in addition the continuous variation of continuous sucking air and air-pressure drop, oil mist particles evaporation
Loss, the concentration for eventually leading to oil mist particles are underestimated；The conversion coefficient K of light scattering method depends on empirical value, measurement result
Accuracy is influenced by instrument calibration.The common gaseous pollutant method of sampling has adsorption tube sampling and Passive sampler, but
The presence of oil mist particles can be such that the concentration of gaseous pollutant is overestimated.Therefore it proposes a kind of first by oil mist particles and gaseous pollutant
It detaches, then the method and apparatus for being sampled, accurately being measured respectively with Electrostatic collection device and Tenax adsorption tubes.
Invention content
It is an object of the invention to overcome in existing oil mist particles sampling technique since fuel spray evaporation leads to granule density quilt
Underestimate, in existing gaseous pollutant sampling technique since the presence of oil mist particles causes what the concentration of gaseous pollutant was overestimated to ask
Topic proposes a kind of device that high-precision oil mist particles measure simultaneously with gaseous pollutant concentration.
The technical solution adopted by the present invention to solve the technical problems is：A kind of high-precision oil mist particles and gaseous pollutant
The device that concentration measures simultaneously, including flow control valve and flowmeter, further include virtual impactor, at the top of the virtual impactor
For air flow inlet, inside is divided into vapor chamber and particle chamber, and the outlet of the vapor chamber is linked in sequence flow-rate adjustment successively with tracheae
The outlet of valve A, flowmeter A, Tenax adsorption tube and vacuum pump A, the particle chamber connect cylindrical shape Electrostatic collection device, the circle
The outlet of tubular Electrostatic collection device passes to tracheae and is linked in sequence successively flow control valve B, flowmeter B and vacuum pump B, the cylinder
Shape Electrostatic collection device connects high voltage power supply.
Outlet of the vapor chamber outlet of the present invention higher than the particle chamber.
The high internal face of cylindrical shape Electrostatic collection device of the present invention is stained with one layer of aluminium-foil paper.
The metal outer wall of cylindrical shape Electrostatic collection device of the present invention passes through ground connection.
The copper wire external high voltage power supply at cylindrical shape Electrostatic collection device center of the present invention.
Advantageous effect
The present invention is separated from the aerosol sampled oil mist particles by virtual impactor, quiet using cylindrical shape
Electric sampler and Tenax adsorption tubes respectively sample oil mist particles and gaseous pollutant, can more accurately measure this two
Partial concentration：
1, oil mist particles are attached to after being collected by cylindrical shape Electrostatic collection device in vertical walls, are reduced and are connect with air-flow
It touches；Oil mist particles are only detached once by virtual impactor, and need not collide with solid shock plate.It is adopted with traditional filter membrane
Sample, inertial impactor sampling are compared, and are reduced the evaporation loss of oil mist particles, can more accurately be measured the dense of oil mist particles
Degree.
2, the gaseous pollutant of stripped oil mist particles is individually sampled, can be avoided due to oil mist particles
There are problems that and over-evaluates gaseous pollutant concentration；Oil mist particles are acquired using only electrostatic methods, it can be to avoid electrostatic ozone pair
The influence of gaseous pollutant analysis.
