Description
Technical field
It the utility model is related to a kind of smoke generating apptss and detection means, more particularly to a kind of oil smoke generating means and inspection
Survey device.
Background technology
Grease, organic matter and the heat resolve or pyrolysis product evaporated in food cooking, process, is referred to as
Oil smoke.Oil smoke is one of principal element of air pollution, and the whole world has 1,600,000 people to die from the lung cancer caused by oil smoke every year.It is edible
300 multiple harmful substances can be produced after oil is heated, wherein polycyclic aromatic hydrocarbons compound (PAHs) is Analyses of major carcinogens in mainstream thing.For a long time
Oil smoke is sucked, tracheitis, bronchitis can be caused, induces various respiratory tract disease, reduces body immunity.Contain cause in oil smoke
Cancer thing BaP, BaP can cause the damage of human body cell chromosome, and long-term suction can induce lung tissue canceration.
At present, oil smoke detection detection means and detection method have：(1) cooking fume discharge standard GB 18483-
2001；(2) the portable cooking oil fume detector HJ 2526-2012 of environmental protection product technical requirements；(3) cooking fume is fast
Fast detection-gas detector method DB31/T 287-2002.
(1)《Cooking fume discharge standard》GB 18483-2001：《Cooking fume discharge standard》GB 18483-
The unique country standard method of the 2001 oil smoke measure announced for China, but pre-treatment of this method to sample needs carbon tetrachloride.
And carbon tetrachloride has been environmentally protected strictly regulating for department after 2009, the production of limitation carbon tetrachloride, buys and use,
And using preceding needing to examine through local environment competent authority, there is larger uncertain factor in time-histories.
The Cleaning Principle of the standard is to extract the gas in oil smoke aiutage using isokinetic sampling's method, and oil smoke absorption is existed
In mist collecting head.The collection filter core that have collected oil smoke is placed in polytetrafluoroethylene sleeve with cover, used after going back to laboratory
Carbon tetrachloride is cleaned by ultrasonic as solvent, is moved into constant volume in colorimetric cylinder, infrared spectroscopy brightness method measure, is absorbed by its is determined
Degree carrys out decision content.Used device includes：Infrared Spectroscopy, oil smoke sampler and filter cylinder, polytetrafluoroethylene (PTFE) cylinder with cover
Shape sleeve, Apparatus for Dust Content in Stack.
Its shortcoming includes：1) the sampling analysis cycle is longer, and step is cumbersome, for example, the sampling analysis of a usual sample
Time need 100min；2) washed completely because carbon tetrachloride solvent can not will filter long-pending greasy dirt when ultrasonic wave cleans in filter cylinder
Only, greasy dirt is caused constantly to accumulate caused, after causing the metal filter cylinders in detection means to be used for multiple times, blank value increases.
(2)《The portable cooking oil fume detector of environmental protection product technical requirements》HJ 2526-2012：《Environmental protection is produced
The portable cooking oil fume detector of product technical requirements》HJ 2526-2012 are Environment Protect in China professional standard, and Main Specification is just
It is to reach as the test required for qualified oil smoke detecting instrument and condition to take formula oil smoke detecting instrument, by that can make after test
For the oil smoke detecting instrument of standard.
Its Cleaning Principle is charged when passing through high voltage electric field using oil smoke particulate, in electric field force and air flow
In the presence of, be pushed to charge-trapping net, electric signal produced in the circuit being connected with charge-trapping net, the change of the signal with
The concentration of discharge oil smoke is in proportionate relationship, and detection signal can obtain oil smoke concentration by processing and conversion.Used device
Including：Quick oil smoke detector.
