Technical field
The present invention relates to experiments to sample fixture fields, concretely relates to a kind of gas dilution device.
Background technique
The concentration of the pollutants such as pellet, nitrogen dioxide, sulfur dioxide is high in atmosphere.Therefore in order to control
Atmosphere pollution is managed, needs to study the chemical substance of the process discharges such as biomass combustion or coal burning, concentration level and big
Secondary generting machanism in gas etc..Therefore, it is necessary to acquire the substance of burning and exhausting to do relevant experiment, however direct burning and exhausting
Material concentration it is excessive, being directly entered instrument analysis will cause the damage of high precision instrument, this just needs a kind of effective gas
Biomass or the product of coal burning etc. are diluted by dilution device, then are 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.
Summary of the invention
To solve the above problems, the present invention proposes a kind of portable gas pollutant dilution device, good mixing effect can connect
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 present invention proposes a kind of portable gas pollutant dilution device, including mixing vessel, described mixed
Closing container includes inlet end and outlet side, and the inlet end of the mixing vessel is provided with sampling gas inlet pipe and Standard Gases import
Pipe, the outlet side of the mixing vessel is provided with diluent gas outlet；Inside the mixing vessel along gas flow direction according to
Secondary to be provided with tapered runner and plane clapboard, the macropore outer rim of the tapered runner is connected with the sealing of mixing vessel inner wall, described
The outer rim of plane clapboard and the inner wall of mixing vessel are tightly connected, and are 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
The material of pipe, tapered runner and plane clapboard is aluminium alloy.
Further, the shape of the mixing vessel is cuboid.
Further, the venthole is arranged on plane clapboard at array.
The utility model has the advantages that the present invention uniformly can rapidly be mixed two kinds of gases by tapered runner and plane clapboard, mix
Effect is good, can continuous sampling dilution, simple structure is light and handy, easy to carry；Total is integrally formed simultaneously, air-tightness is good,
Failure rate is low；By being respectively set on sampling gas inlet pipe, standard gas inlet pipe, diluent gas outlet and residual air outlet
Flowmeter controls extension rate.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the left view of tapered runner；
Fig. 3 is the left view of plane clapboard.
Specific embodiment
Such as Fig. 1, one embodiment of the present of invention, the mixing vessel 1 including rectangular shape, the mixing vessel 1 includes
The inlet end being oppositely arranged and outlet side, the inlet end of the mixing vessel are provided with sampling gas inlet pipe 2 and Standard Gases import
The outlet side of pipe 3, the mixing vessel 1 is provided with diluent gas outlet 4 and residual air outlet 8.Sampling gas inlet pipe 2 is used for
Gas to be diluted is imported, standard gas inlet pipe 3 is diluted for importing Standard Gases, the export dilution of diluent gas outlet 4
Gas afterwards to laboratory apparatus, residual air outlet 8 can arrange gas after extra dilution according to the demand of gas after dilution
Out, 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
For 10:1.Flowmeter on diluent gas outlet 4 and residual air outlet 8, which can according to need, to be precisely controlled into laboratory apparatus
Dilution after gas tolerance, while excessive gas being discharged.For example, total air inflow of inlet end is 10L/min, laboratory apparatus
Demand intake velocity be 1.5L/min, adjustment residual air outlet 8 outlet speed be 8.5L/min.
The mixing vessel 1, sampling gas inlet pipe 2, standard gas inlet pipe 3, diluent gas outlet 4, residual air outlet
8, the material of tapered runner 5 and plane clapboard 6 is aluminium alloy, and intensity is high, corrosion-resistant.
