Description
Technical field
It can disperse to absorb bubble diameter the utility model relates to a kind of band porous plate, hot tail gas filters absorption of device, tail gas
The large-scale impinger of drying device belongs to environmental monitoring, labour health monitoring, public health monitoring field.
Background technique
Pollutants in air (aerosol etc.) detection, by being sent into lab analysis after spot sampling.Gaseous pollutant is logical
Cross constant flow sampler and impinger enter absorbing liquid, laboratory by standard solution draw standard curve to absorbing liquid into
Row quantitative analysis calculates the testing result of final air pollutants, therefore gaseous pollutant enters the absorptivity meeting of absorbing liquid directly
Connect the accuracy for influencing testing result.
Existing impinger, pollutants in air by absorb bottom of the tube quickly spray, misty aerosol particle because
Inertia impact is to absorption bottle bottom, then absorbed liquid detention, but existing impinger is only used for aerosol contact scar object, no
It can be used for gaseous pollutant, because gas molecule inertia is small, also quickly flowed out with sample gas under fast pump state, absorbing liquid
Absorptivity it is very low.Therefore, the absorptivity for improving impinger can expand the use scope of absorption tube, while improve sky
The accuracy of contaminant detection results in gas.
Common absorbing liquid chemical component containing acid-base property, has corrosiveness to sampler.Impinger is directly connected to
Often there is suck-back phenomenon in sampler, i.e. absorbing liquid sucks sampler, damages sampler.At present with sebific duct in absorption tube and sampling
Between device plus safety flack is connected, the risk of suck-back is reduced, but also reduce the airtightness of gas flow loop simultaneously, makes sampling flow error
Increase.Sampler passes through conversion sample gas volume after traffic alignment, and sample gas volume accuracy influences laboratory mark pollution

It is connected again with sebific duct, is unfavorable for carrying and spot sampling operates, air-leakage test and attended operation are cumbersome, airtight after series connection
Property it is impacted so that flow and calibrated fluxes is generated certain error, influence final calculation result.Gaseous pollutant passes through delay absorption
After form tail gas, into sampler air intake, be discharged finally by sampler gas outlet, tail gas relative humidity increases, and takes simultaneously
With chemical component volatile in absorbing liquid, corrodes sampler, endanger operator.
Existing impinger is only used for aerosol contact scar object, without safety flack and tail gas filter.Therefore existing
Have in technology there is an urgent need for the absorptivity that a kind of novel technical solution improves impinger, improves pollutants in air inspection
The accuracy for surveying result, expands the use scope of impinger.Increase tail gas filter, filter tail gas in water content and
Soda acid ingredient protects sampler and operator.
