Description
Technical field
The utility model belongs to environmental monitoring scientific domain, is related to a kind of test dress for determining BaP content in flue gas
Put.
Background technology
BaP is also known as benzo [α] pyrene, 3,4- BaPs, and english abbreviation BaP is polycyclic aromatic hydrocarbons compound, existed
In the flue gas, smoke from cigarette, vehicle exhaust that the burning such as coal tar, all kinds of carbon blacks and coal, oil is produced, and coking, oil refining,
In the trade effluents such as pitch, plastics.Benzo [α] pyrene be have in the carcinogenic polycyclic arene compound of kind more than 200 having found it is strong
The representative compound of carcinogenicity.Benzo [α] pyrene is 80 μ g to half carcinogenicity test of experimental animal, and minimum carcinogenicity test is not
It is just of great interest with research to 2 μ g, therefore since being found from it.
BaP content in coke oven flue gas, especially raw coke oven gas is higher, has necessarily to coke-oven plant worker and nearby residents
BaP content is higher in influence, empirical tests Coking Plant Workers urine, and coke-oven plant's workshop workman dermal melanin is calm, ill
Rate is higher.BaP is effectively administered, it is necessary to there is the accurate monitoring means of science to support.
Foundation《The measure acetylation filter paper layer folding fluorescence spectrophotometry of benzo a pyrenes in air quality floating dust》（GB
8917-88）、《Surrounding air benzo a pyrenes determine high performance liquid chromatography》（GB/T 15439-1995）、《Stationary source is arranged
The measure high performance liquid chromatography of benzo a pyrenes in gas》（HJ/T 40-1999）Standard is by ultra-fine fibre glass filter membrane or filter cylinder
Trapping；Publication No. CN201867398U utility model patent discloses a kind of BaP automatic testing equipments, can monitor in real time
The concentration of environment BaP, the invention is acquired using filter cylinder, but because filter cylinder is easily blocked, causes instrument failure rate
It is higher.The B of Publication No. CN 102706979 patent of invention discloses the BaP concentration in air can be detected
Method and apparatus, the patent causes particle negatively charged by the negative ion generating device of electrostatic collection device, so as to be adsorbed onto band
Mode on the particle collection device of positive electricity is sampled, and the shortcoming of this sample mode is that cost is high, easily punctured, adsorption efficiency
Limited by ratio resistance, dust specific resistance is in 104-1011（Ω cm) beyond scope, adsorption efficiency is remarkably decreased, or even can not
Adsorbed, cause monitoring result to reflect pollutant discharge of enterprise situation, and this is nor the BaP monitoring methods of national regulations.
Publication No. CN201867398U utility model patent and the B of Publication No. CN 102706979 patent of invention are using super
Sound wave extractor but is restricted as the pre-processing device of the smoke-dust trapped by ultrasonic attenuation factor, and ultrasound is effectively
The zone of action is an annular, if the diameter of extractor is too big, center will form ultrasonic clear area；Effect is extracted if meeting
Fruit uses big power, then has that ultrasonic equipment manufacture difficulty is big, while cost also high shortcoming.
The content of the invention
The purpose of this utility model is to provide a kind of test device for determining BaP content in flue gas.
The utility model is achieved through the following technical solutions：
The test device of BaP content in a kind of measure flue gas, including take gas unit, collecting unit, detection unit；
It is described to take gas unit to be to be provided with air pump and the heat resisting steel of meter takes tracheae；
Described collecting unit includes the vasculum for being built-in with the corundum filter cylinder for the taper that Open Side Down and detection flow container, institute
The vasculum connection blast pipe and feed tube for the corundum cartridge top portion stated, the vasculum connection heat resisting steel of bottom take tracheae, circulation
Vasculum is connected to form circulation by liquid pipe and discharging tube, described feed tube with circulation liquid pipe with detection flow container, described corundum
Fix bar is symmetrically arranged with the outside of the barrel in the cylinder centre position of filter cylinder, fix bar passes through the tank wall of vasculum, and end is stretched out
On the outside of the vasculum, the cylinder of described corundum filter cylinder is while provided with the extension stretched out；
Described detection unit is gas chromatograph, is connected with the discharging tube of vasculum bottom；
Above-mentioned all pipelines are equipped with valve.
Further, the aperture of described corundum filter cylinder is 0.35-0.45 microns.
Power nozzles are provided with the top of described vasculum, described power nozzles are connected with feed tube.
Described vasculum is cylinder collection casing, and head clearance is provided with the power nozzles of more than 2.
During operation, tracheae is taken to be placed at flue gas to be measured in the heat resisting steel for taking gas unit, booster air pump and meter are opened resistance to
Hot steel takes the valve on tracheae and blast pipe, starts to take gas, and now flue gas is filtered from vasculum bottom by the corundum that Open Side Down
Entrained BaP is filtered in corundum cartridge wall in cylinder, flue gas and particle, to be achieved to take after tolerance, closes air pump and valve
Door, then opens feed tube and circulation liquid pipe, will detect that liquid is sprayed on the corundum filter cylinder built in vasculum through power nozzles, will filter
The flue dust backward erosion carried on barrel, BaP is dissolved in detection liquid, and repeatedly circulates so that BaP is substantially soluble in detection liquid
