For overcoming the defects of the existing flue sampler the utility model comprises an intake part, a flue gas air mixed diluted particles classified sampling part, and an exhaust part, the flue gas air mixed diluted particles double-channel classified sampling part comprises a dilution channel inner barrel, an external barrel, a double channel, a cutting head, and a filter, the sampler can collect various particles in the different particle size range discharged organizedly from a stationary source, and the monitoring work need can be satisfied completely.
Description
Technical field
The utility model relates to a kind of flue dust class sampling thief, and particularly a kind of sampling thief of gathering aerosol sample in stationary source discharged flue gas and the surrounding air mixed gas belongs to the environmental monitoring technology field.
Background technology
The particle that stationary pollution source discharges in a organized way exists with aerosol shape, is one of main source of particle in the surrounding air.Utilize the flue sampling thief to obtain the aerosol sample of fixed-contamination source emission, study the chemical composition of the particle of its size-grade distribution and different-grain diameter, for monitoring: the pollution level of surrounding air, important practical value all arranged to whether appropriate health effects degree and the pollution control measures taked etc.
The producer of the flue of China's production at present product sampler is a lot, as Qingdao LaoShan Application Technology Research Institute, and Wuhan rainbow enviromental protection instrument factory etc.The flue sampling thief of these manufacturer production is the cyclone type sampling thief mostly, and this type of apparatus structure signal has following defective in actual applications as Fig. 1:
1) do not have flue dust particle diameter segmenting device, what mainly gather is the full aerosol sample of flue dust.Often need in actual applications to determine to discharge in the chimney the size distribution of particle, as the percentage by weight of bulky grain thing (below 100 microns) and small particle (below 10 microns), and determine the source strength of different-grain diameter particle with this.But above-mentioned instrument can not reach this requirement.
2) said apparatus adopts the filter cylinder dust collect plant mostly, as the glass fibre filter cylinder.This dust collect plant can make the flue dust of considerable part accumulate in and cause the collection difficulty in the fiber holes.Organism and inorganics that existing on the other hand glass fibre filter cylinder contains are more, are not suitable for element, ion and organic analysis, become open score to produce difficulty to the flue dust of setting up different-grain diameter.
3) on the present China market a kind of in addition " impact type particulate cascade instrument ".This instrument adopts " impact type " principle that grit is cut, weighs to determine the shared percentage by weight of particle in the different-grain diameter scope.But this sampling thief also just cuts the grit in the design particle size range, and other particle diameter components in proportions then can only be estimated by mathematical statistics methods such as recurrence.Because this instrument often can not obtain the particulate matter in the needed particle size range, so equally also can't set up needed derived components spectrum.
Summary of the invention
The utility model is in order to overcome the defective of existing various stationary source smoke dust sampling instruments, the specialized designs of carrying out under the condition that satisfies the aerodynamics sampling request.
The technical solution of the utility model: the utility model is made up of induction part, flue gas air mixed dilution particulate cascade sampling part, exhaust portion three parts of grading.Surrounding air (12) enters bucket (5) in the dilution tunnel by air damper 1 (15), compressed air cleaner (16), air nozzle (17) successively through air compressor (11); Flue gas stream (8) also enters bucket (5) in the dilution tunnel through sampling rifle (9) and flue gas stream inlet tube (27), and the decline baffling enters bucket (26) outside the dilution tunnel in interior bucket, and mixed gas upwards flows in the bucket outside, enters PM
10Cutting head (7) and PM
2.5Cutting head (23), the aerosol sample in the specified particle diameter scope in the while flue gas is cut head and collects, and gas continues to discharge from sampling pump (25) by air damper 2 (19); Other has portion gas to pass through air damper 3 (24) by gas outlet tube, discharges through sampling pump (25).
The beneficial effects of the utility model:
Can realize the flue dust isokinetic sampling, can realize that flue gas enters the evolution condition of approaching real physics, chemistry in the surrounding air, satisfy under the above-mentioned sampling condition, can collect PM simultaneously
10And PM
2.5The aerosol sample that stationary source in the particle size range discharges in a organized way satisfies the requirement of detection and research work.
