Description
Technical field
The present invention relates to field of environmental protection detection, a kind of two English on-line measuring devices.
Background technology
Two English are chloro dibenzo two English and the general designation of chloro dibenzofurans, because of its have extremely strong carcinogenecity,
Bioconcentrations etc. endanger, by the extensive concern of international community.Two English are be not intended to during human being's production to produce organic
Pollutant, source is very wide, and wherein incineration of waste is considered as one of main generation source.It is clear crystal shape at normal temperatures
State, under low temperature, chemical property is the most stable, but temperature more than 750 DEG C time, easily decompose.Two English fusing points are high, boiling point is high, not only
To soda acid, and the most stable under redox.The most easily it is decomposed under ultraviolet irradiation, and in biological agent
Under then decompose the slowest, easily by adsorption by soil, be highly soluble in fat, easily at people's cylinder accumulation.The danger that two English are maximum
Evil is to have teratogenesis, carcinogenic, mutagenicity.Two English are the one that the Environmental Hormone toxic recognized at present is maximum.
The detection method of current two English is mainly high-resolution hydrolysis and condensation and the Measurement for Biotechnique of off-line, ripe two
English on-line measuring device does not also have actual application.
Summary of the invention
The technical problem to be solved is for above-mentioned present situation, it is provided that a kind of energy on-line checking two English concentration
Device.
The present invention solves the technical scheme that above-mentioned technical problem used: by hothouse, gravitational precipitator, laser particle
Enumerator I, heated at constant temperature room, ultraviolet light source, cooling chamber, laser particle counter II, air pump and intelligent processor composition.
As improvement, hothouse, gravitational precipitator, laser particle counter I, heated at constant temperature room, cooling chamber, laser particle
Enumerator II, air pump connect composition measure loop by pipeline, and ultraviolet light source is arranged on heated at constant temperature room and makes ultraviolet
Line irradiates into heated at constant temperature indoor, and the air inlet of hothouse is connected sampling, at air pump with the air vent of tapping equipment to be measured
Under effect, gas sampled drying room, gravitational precipitator, laser counter I, heated at constant temperature room, cooling chamber, laser counter II
After from air pump discharge.
Improve again, hothouse preferred desiccant absorbent-type, gravitational precipitator preferred Whirlwind cyclone dedusting method, heated at constant temperature room
Selecting heating-up temperature 750-800 DEG C, ultraviolet light source shines enters heated at constant temperature room.
Improving, laser particle counter I, laser particle counter II are solid in the real-time detected gas of shading principle again
Grain quantity, respectively 2 μm, 5 μm, 15 μm, 25 μm, 50 μm, 100 μm granule numbers in statistical unit volumes of gas.
Improve again, hothouse, gravitational precipitator, laser particle counter I, heated at constant temperature room, cooling chamber, laser particle meter
It can also be 2-50 that number device II, air pump number can be 1.
As improving further, intelligent processor includes digital sampling and processing and display module, with laser particle
Enumerator I, laser particle counter II line connect composition process, show circuit.
Compared with prior art, the present invention utilizes two English ins and outs and prior art condition, by grain count pair
Ratio amounts of particles in unit-gas before and after two scruple solutions, by off-line calibration, completes two English in gas to be measured and relatively contains
Amount and the detection of absolute content, have important environment protection significance.
Accompanying drawing explanation
Fig. 1 is the structure principle chart of the embodiment of the present invention；
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
As it is shown in figure 1, the embodiment of the present invention is by hothouse 1, gravitational precipitator 2, laser particle counter I3, heated at constant temperature
Room 4, ultraviolet light source 5, cooling chamber 6, laser particle counter II7, air pump 8 and intelligent processor 9 form.Hothouse 1, weight
Inertia force precipitator 2, laser particle counter I3, heated at constant temperature room 4, cooling chamber 6, laser particle counter II7, air pump 8 pass through
Pipeline connects composition measure loop, and ultraviolet light source 5 is arranged on heated at constant temperature room 4, the air inlet of hothouse 1 and discharge to be measured
The air vent of device 10 connects sampling, under the effect of air pump 8, gas sampled drying room 1, gravitational precipitator 2, laser meter
Discharge from air pump 8 after number device I3, heated at constant temperature room 4, cooling chamber 6, laser counter II7.
The preferred desiccant absorbent-type of hothouse 1, the preferred Whirlwind cyclone dedusting method of gravitational precipitator 2, heated at constant temperature room 4 selects
Heating-up temperature 750-800 DEG C, ultraviolet light source 5 irradiates in heated at constant temperature room 4.Laser particle counter I3, laser particle meter
Number device II7 is solid particle quantity in the real-time detected gas of shading principle, respectively 2 μm, 5 μm, 15 μ in statistical unit volumes of gas
M25 μm, 50 μm, 100 μm granule numbers.Intelligent processor 9 includes digital sampling and processing and display module, with laser particle
Enumerator I3, laser particle counter II7 line connect composition process, show circuit.Hothouse 1, gravitational precipitator 2, laser
Grain enumerator I3, heated at constant temperature room 4, ultraviolet light source 5, cooling chamber 6, laser particle counter II7, air pump 8 number are permissible
Being 1 can also be 2-50.
The operation principle of the present invention is as follows: during detection start air pump 8, the air vent of tapping equipment 10 to be measured some
Gas sampled enters in hothouse 1, by the moisture removal in gas sampled, enters back into gravitational precipitator 2 by gas sampled
The dust that density is bigger is removed, and enters back into 2 μm in laser particle counter I3 detection unit sample gas, 5 μm, 15 μm 21 μ
M, 50 μm, 100 μm granule numbers, these granules include two English and some other difficult dust decomposed, enter back into constant temperature and add
Hot cell 4, under the effect of the high temperature of 750-800 DEG C and ultraviolet light source 5, two English in gas sampled resolve into gas, through cold
But room 6 cooling after enter back into laser particle counter II7 detection unit sample gas in 2 μm, 5 μm, 15 μm 21 μm, 50 μm,
100 μm granule numbers, send intelligent processor 9 by twice detected value, compare and analyze the two English phases drawing in gas sampled
Content is shown, real-time two English absolute contents can be obtained by off-line calibration.
