The chemical substance of the process discharges such as matter burning or coal burning, concentration level and secondary generting machanism in an atmosphere etc..Cause
This, the substance for needing to acquire burning and exhausting does relevant experiment, however the material concentration of directly burning and exhausting is excessive, is directly entered
Instrument analyzes the damage that will cause high precision instrument, this just needs a kind of effective gas dilution device, by biomass or coal
The product etc. of burning is diluted, then is passed through instrument analysis.
The dilution device of the prior art, the device being made of three wide-mouth bottles, bottle stopper and several conduits, wide-mouth bottle pass through
Conduit interconnects, and gas continues through three bottles to reach diluted purpose.There are extension rates for such dilution device
The problems such as small, poor air-tightness, portability are low, inconvenient.Meanwhile wide-mouth bottle and conduit are glasswares, especially conduit,
Frangible.
Utility model content
To solve the above problems, the utility model proposes a kind of portable gas pollutant dilution device, good mixing effect,
Can continuous sampling dilution, simple structure is light and handy, easy to carry, air-tightness is good, failure rate is low, and extension rate is controllable.
Technical solution: the utility model proposes a kind of portable gas pollutant dilution device, including mixing vessel, institutes
Stating mixing vessel includes inlet end and outlet side, the inlet end of the mixing vessel be provided with sampling gas inlet pipe and Standard Gases into
Mouth pipe, the outlet side of the mixing vessel is provided with diluent gas outlet；Along gas flow direction inside the mixing vessel
It is disposed with tapered runner and plane clapboard, the macropore outer rim of the tapered runner is connected with the sealing of mixing vessel inner wall, institute
The inner wall of the outer rim and mixing vessel of stating plane clapboard is tightly connected, and is additionally provided with several ventholes on plane clapboard.
Further, the outlet side of the mixing vessel is additionally provided with residual air outlet.
Further, on the sampling gas inlet pipe, standard gas inlet pipe, diluent gas outlet and residual air outlet respectively
It is provided with flowmeter.
Further, the mixing vessel, sampling gas inlet pipe, standard gas inlet pipe, diluent gas outlet, residual air outlet

Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the left view of the tapered runner of the utility model；
Fig. 3 is the left view of the plane clapboard of the utility model.
Specific embodiment
Such as Fig. 1, one embodiment of the utility model, the mixing vessel 1 including rectangular shape, the mixing vessel 1
Including the inlet end being oppositely arranged and outlet side, the inlet end of the mixing vessel is provided with sampling gas inlet pipe 2 and Standard Gases
The outlet side of inlet tube 3, the mixing vessel 1 is provided with diluent gas outlet 4 and residual air outlet 8.Sample gas inlet pipe 2
For importing gas to be diluted, standard gas inlet pipe 3 is diluted for importing Standard Gases, and diluent gas outlet 4 exports
For gas after dilution to laboratory apparatus, residual air outlet 8 can be according to the demand of gas after dilution, by gas after extra dilution
Body discharge, balance disengaging tolerance, prevents the gas pressure in mixing vessel 1 excessively high.
Tapered runner 5 and plane clapboard 6, the cone are disposed with along gas flow direction inside the mixing vessel 1
The outer rim of shape runner 5 is connected with the sealing of 1 inner wall of mixing vessel, and the outer rim of the plane clapboard 6 and the inner wall of mixing vessel 1 seal
It connects, several ventholes 7 is additionally provided on plane clapboard 6, venthole 7 is that array is arranged in the circular hole on plane clapboard 6.From adopting
The gas that sample gas inlet pipe 2 and standard gas inlet pipe 3 flow into flows through tapered runner 5, and air-flow forms then effect that convergence is sprayed,
Enhance mixed effect.Gas passes through the venthole 7 of the arrangement of the array on plane clapboard 6, uniformly spreads, further progress
The mixing of two kinds of gas, then the gas after mixed diluting is flowed out from diluent gas outlet 4 and residual air outlet 8.
It is set respectively on the sampling gas inlet pipe 2, standard gas inlet pipe 3, diluent gas outlet 4 and residual air outlet 8
It is equipped with flowmeter.Flow is monitored by the flowmeter in sampling gas inlet pipe 2 and standard gas inlet pipe 3, can be precisely controlled dilute
Release multiple.For example, gas flow rate control to be diluted is in 1L/min, calibrating gas flow control is in 9L/min, then extension rate
