The gas sampling probe provided by the utility model has the advantages that a sample can be collected at multiple points, and the collection points can be controlled.
Description
Technical field
The utility model relates to a kind of pick-up unit, is specifically related to a kind of gas sampling probe.
Technical background
It is an important step in environmental monitoring that gas detects.Along with people are to the improving constantly of working environment and living environment consciousness, we also improve constantly its monitoring means.Sampling probe is the critical component on gas on-line monitoring system, is used in flue or gas in pipelines sampling, or large-scale workplace, for example sanitary fill, large scale industry factory etc.During detection, need to filter the gas extracting, keep constant temperature, to guarantee next step instrument measurement precision.Yet existing sampling probe has several drawbacks in the market, single-point sampling filtering most importantly.Extract the gas of some points, for there is no representativeness in whole environment.Can not realize multiple spot extracts.In addition, existing sampling probe filter core adopts individual layer precision, is generally 0.5 μ m-2 μ m, selects precision too high, stops up and replacement frequency increasing; The too little effect that does not have again filtration of precision.
Utility model content
The utility model object be to provide a kind of can multipoint acquisition sample, and can control the gas sampling probe of collection point.
For reaching above-mentioned purpose, provide following technical scheme:
A gas sampling probe, comprises sampling thief, filtration unit and gas path pipe, and described sampling thief is connected by described gas path pipe with described filtration unit; Described sampling thief is provided with thief hatch, and described filtration unit is provided with exhausr port; Described filtration unit inside is provided with filter core; Described sampling thief is more than two; Described sampling thief inside is provided with sampling thief filtration unit; Described sampling thief is detachable being connected with described gas path pipe.
As a preferred version, described sampling thief with described gas path pipe for being threaded.
As another preferred version, also comprise thermostatically-controlled equipment; Described thermostatically-controlled equipment is arranged on the outside of described filtration unit, and described filtration unit is coated.By described thermostatically-controlled equipment is set, can carry out temperature control to the gas sample gathering, be conducive to improve follow-up pattern detection analysis.
As another preferred version, also comprise from clearing apparatus, describedly from clearing apparatus, be connected with described filtration unit.As further preferred version, describedly from clearing apparatus, be provided with pulse control unit.By described, from clearing apparatus, utilize pressurized air automatically to purge described filter core, extend described filter core serviceable life.Utilize described pulse control unit to carry out pulse protocol control, produce similar compression big gun principle and carry out face blowback, can improve the effect of purge.
As another preferred version, also comprise handle, described handle is connected with described filter core, and described handle is arranged on the shell of described gas sampling probe; Described filter core by described handle detachable to be arranged on described filtration unit inner.As further preferred version, the described filter core described handle that is threaded; The described handle described gas sampling probe that is threaded.Be threaded connection, described filter element replacing, without any instrument, by dismantling described handle, is pulled down described filter core, more described handle is pulled down from described filter core from described filtration unit, just can change described filter core.
As another preferred version, sampling thief is 5.
Compared with prior art, the utility model has the advantage of: by a plurality of described sampling thiefs are set, sampled point can be arranged on to the zones of different of environment to be measured, improve the representativeness of collecting sample, improve sampling efficiency, improve control accuracy and blowback efficiency.In addition, by the built-in described sampling thief filtration unit of described sampling thief, play the effect of classified filtering.The precision having there will be while having avoided single layer filter is too high, stops up filter plant and replacement frequency too high; The too little situation that does not have again the effect of filtration of precision.Dismountable mode is installed described sampling thief can change described sampling thief, to reach the technique effect of changing described sampling thief filtration unit, not only can play the clean described sampling thief filtration unit of changing, can also control the process of filtering, regulate the filtering accuracy of primary filter.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model:
Fig. 1 is structural representation of the present utility model.
Embodiment
For making technological means of the present utility model, reach object and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
An embodiment of the present utility model is:
A gas sampling probe, comprises sampling thief 1, gas path pipe 2, filtration unit 3, thermostatically-controlled equipment 4, from clearing apparatus 5 and handle 6, and sampling thief 1 is connected by gas path pipe 2 with filtration unit 3; Sampling thief 1 is provided with thief hatch 7, and filtration unit 3 is provided with exhausr port 8; Filtration unit 3 inside are provided with filter core 9; Sampling thief 1 is five; Sampling thief 1 inside is provided with sampling thief filtration unit 10; Sampling thief 1 with gas path pipe 2 for being threaded.Thermostatically-controlled equipment 4 is arranged on the outside of filtration unit 3, and filtration unit 3 is completely coated.From clearing apparatus 5, be connected with filtration unit 3.From clearing apparatus 5, be provided with pulse control unit 13.From clearing apparatus 5, be provided with from purge hole 11 and cleaning vent port 12.Handle 6 is connected with filter core 9 screw threads; Handle 6 is threaded from clearing apparatus 5, and filter core 9 is by detachable being arranged among filtration unit 3 of handle 6.
By the connection of gas path pipe 2, five sampling thiefs 1 can be arranged on the default position of user, sampled point is arranged on to the zones of different of environment to be measured, improve the representativeness of collecting sample, improve sampling efficiency, improve control accuracy and blowback efficiency.First the gas to be measured collecting by being built in the sampling thief filtration unit 10 in collector 1, filter for the first time.Then the gas to be measured that five collectors 1 collect enters filtration unit 3 by gas path pipe 2, by filter core 9, carries out secondary filtration.Twice filtration by such, has not only improved filter effect, and the precision there will be while having avoided single layer filter is too high, stops up filter plant and replacement frequency too high; The too little situation that does not have again the effect of filtration of precision.The thermostatically-controlled equipment 4 that is arranged on filtration unit 3 outsides has played the effect of controlling gas temperature to be measured, contributes to guarantee the accuracy of subsequent detection.Through the gas to be measured filtering, pass through successively exhausr port 8 and cleaning vent port 12.Cleaning vent port 12 places can connect checkout equipment, and the gas to be measured collecting is detected to analysis.
From clearing apparatus 5, utilize pressurized air from carrying out aeration cleaning filter core 9 from purge hole 11.Pulse control unit 13 provides pulse protocol to control, and produces similar compression big gun principle and carries out blowback, better clean filter core 9.
