Description
Technical field
It the utility model is related to air particle Sampling techniques field, and in particular to a kind of particulate matter for eliminating droplet and influenceing
Sampler.
Background technology
When sampling progress particle concentration detection to gas particles thing, if the humidity of sample gas is bigger, wherein
There can be small droplet, the presence of droplet can give the precision of detection to bring greater impact.Particulate matter is being collected using filter membrane
Sampler in, droplet, which is mixed in sample gas, to be trapped by filter membrane, be also difficult to be completely eliminated droplet to adopting even across drying
The influence of sample.And the direct-reading particle sampler of optical method is used, the optical characteristics base of droplet and particulate matter in sample gas
This is identical, and optics direct-reading module cannot be distinguished by droplet and particulate matter, therefore droplet can bring very big influence to sampled measurements, cause
Reading greatly deviates from actual value.
Droplet in sample gas directly affects the testing result of particle concentration, it is therefore desirable to eliminates the droplet in sample gas.
At present mostly using heating and dehumidification method, by heating the temperature of raising sample gas, so as to reduce the relative humidity of sample gas, to disappear
Except the influence of droplet.Heating-up temperature is not high, effect on moisture extraction unobvious, but heating-up temperature it is too high can cause it is volatile in particulate matter
The loss of material, also directly affect final measurement result.Therefore the effect of heating and dehumidification is unsatisfactory.
The content of the invention
The purpose of this utility model is to provide a kind of particle sampler for eliminating droplet and influenceing, and the device can be effective
Eliminate the influence that droplet is brought to particle sampling in sample gas.
To achieve these goals, the utility model adopts the following technical scheme that：A kind of particulate matter for eliminating droplet and influenceing
Sampler, including sampling module, air distribution module, negative pressure module and particulate matter detection module, the sampler also include one
Individual threeway and measurement module, the measurement module include by-pass gauge and main road flowmeter, and the sampling module is connected to institute
One end of threeway is stated, the air distribution module is connected to one end of the threeway, the threeway by the by-pass gauge
The other end be sequentially connected in series the particulate matter detection module, the main road flowmeter is connected to the negative pressure module.
Further, the air distribution module is connected with the by-pass gauge by pipeline, is set on the pipeline
There is heater.The heater is electric heater unit.The heater is the heating tape being wrapped on pipeline outer wall.
Further, the air distribution module includes being sequentially connected air pump, air filter and it is air-dried dress
Put；Either the air distribution module is Zero gas generator or the air distribution module is to be placed with clean dry air
Air accumulator.
Further, the sampling module is sampling head.
Further, the negative pressure module is aspiration pump.
Further, the particulate matter detection module is filter membrane or laser straight read through model.
The particle sampler of the present utility model for eliminating droplet and influenceing, it is simple in construction, it is easy to use, by high humility
Sample gas in the dry air of mixing cleaning, the relative humidity of the sample gas of high humility can be quickly reduced to saturation
Below humidity so that condensate is not present before entering filter membrane or direct-reading module in sample gas, effectively eliminates in sample gas
Influence of the droplet to particle sampling precision.

Embodiment
Content of the present utility model is described in detail with reference to embodiment.
As shown in figure 1, the particle sampler of the present utility model for eliminating droplet and influenceing, including sampling module 1, air are matched somebody with somebody
Module 6, negative pressure module 5, particulate matter detection module 7, measurement module and a threeway 3 are sent, wherein measurement module is mainly to entering
The flow for entering the gas in sampler measures, including by-pass gauge 2 and main road flowmeter 4.Sampling module 1 is one and adopted
Sample head, sampling head and one end of threeway 3 are tightly connected.Air distribution module 6 is connected to the one of threeway 3 by by-pass gauge 2
End, air distribution module 6 are mainly to provide cleaning dry air into sampler.Dispensing module 6 in the present embodiment can be with
For an air accumulator for being pre-placed clean dry air, cleaning can also be produced online to be a set of in a further embodiment
The device of dry air, the device for producing clean dry air online can be the higher Zero gas generator of cost, or
Air pump, air filter and the air dry-set being sequentially connected, as long as outside air can be made to the dry sky of cleaning
Gas.Air distribution module 6 is connected with by-pass gauge 2 by pipeline, and heating tape is provided with pipeline, can be by heating tape
It is wrapped on the outer wall of pipeline, in order to preferably heat the dry air of cleaning, air distribution module 6 and by-pass can be increased
The length of pipeline between gauge 2.The dry hot-air of cleaning can further reduce the humidity of sample gas.Threeway 3 it is another
