Abstract
The invention discloses a smoke sampler capable of realizing representative sampling. The smoke sampler capable of realizing representative sampling comprises a smoke collecting pipe, an air pump, a first cyclone collector, a second cyclone collector, a three-way pipe, a micromanometer, a switching valve and an atmosphere collecting pipe, wherein detection rods are arranged on upper and lower surfaces of the smoke collecting pipe and connected with a measuring end of the micromanometer through leads, the back end of the smoke collecting pipe is connected with the first cyclone collector through a pipeline, the first cyclone collector is connected with the second cyclone collector through a pipeline, and the second cyclone collector is connected a first end of the three-way pipe through a pipeline. According to the smoke sampler, collecting speeds of solids and gases in smoke can be equal, so that collected smoke samples are representative; the first cyclone collector and the second cyclone collector are arranged, so that the smoke samples can be fully collected.
Description
Technical field
The present invention relates to a kind of smoke dust sampling instrument, particularly relate to and a kind ofly sample representative smoke dust sampling instrument.
Background technology
Smoke contamination present situation is along with the fast development of economic society, more and more serious, especially winter just snowed within several days, will black be become, therefore monitor and monitor even more important to the soot emissions of contaminated environment, smoke dust sampling instrument is the pith of soot emissions monitoring, existing smoke dust sampling instrument sampling representativeness is not strong, make the poor accuracy of the concentration of solid and gas in the flue gas finally obtained, and then collect use because flue gas is sucked by collection tube, often have the situation that partial fume is not collected, the accuracy of final test result will be affected.
Summary of the invention
Object of the present invention is just that providing a kind of to solve the problem samples representative smoke dust sampling instrument.
In order to achieve the above object, present invention employs following technical scheme:
A kind ofly sample representative smoke dust sampling instrument, comprise flue dust collection tube and aspiration pump, describedly a kind ofly sample representative smoke dust sampling instrument and also comprise the first cyclone collector, second cyclone collector, three-way pipe, microbarograph, switch valve and air collection tube, the top and bottom of described flue dust collection tube are equipped with test bar, two described test bars are all connected by the measuring junction of wire with described microbarograph, the rear end of described flue dust collection tube is connected with described first cyclone collector by pipeline, described first cyclone collector is connected with described second cyclone collector by pipeline, described second cyclone collector is connected by the first end of pipeline with described three-way pipe, second end of described three-way pipe is connected with described air collection tube by pipeline, pipeline between described three-way pipe and described air collection tube is provided with switch valve, 3rd end of described three-way pipe is connected with the air inlet end of described aspiration pump, said structure, makes the picking rate of solid and gas in flue gas equal, ensure that the smoke sample that the present invention gathers is representative, and then improves the accuracy of concentration of solid and gas in the flue gas that finally obtains.
In said structure, the first cyclone collector and the second cyclone collector, make the fume sample of collection be collected fully, and then ensure that the accuracy of final test result.
Particularly, the top and bottom of described flue dust collection tube are equipped with static opening, and two described static openings are connected with two described test bars respectively, and the central authorities of two described test bars are equipped with through hole; High temperature resistant heat insulation coating is scribbled in described flue dust collection tube; Organosilicon coating is scribbled in described flue dust collection tube.

Accompanying drawing explanation
Fig. 1 is a kind of structural representation sampling representative smoke dust sampling instrument of the present invention.
In figure: 1-flue, 2-flue dust collection tube, 3-wire, 4-test bar, 5-first cyclone collector, 6-second cyclone collector, 7-three-way pipe, 8-aspiration pump, 9-microbarograph, 10-switch valve, 11-air collection tube.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1, the present invention is a kind of samples representative smoke dust sampling instrument, comprise flue dust collection tube 2 and aspiration pump 8, aspiration pump is a kind of to be sampled representative smoke dust sampling instrument and also comprises the first cyclone collector 5, second cyclone collector 6, three-way pipe 7, microbarograph 9, switch valve 10 and air collection tube 11, the top and bottom of aspiration pump flue dust collection tube 2 are equipped with test bar 4, two aspiration pump test bars 4 are all connected by the measuring junction of wire 3 with aspiration pump microbarograph 9, the rear end of aspiration pump flue dust collection tube 2 is connected with aspiration pump first cyclone collector 5 by pipeline, aspiration pump first cyclone collector 5 is connected with aspiration pump second cyclone collector 6 by pipeline, aspiration pump second cyclone collector 6 is connected by the first end of pipeline with aspiration pump three-way pipe 7, second end of aspiration pump three-way pipe 7 is connected with aspiration pump air collection tube 11 by pipeline, pipeline between aspiration pump three-way pipe 7 and aspiration pump air collection tube 11 is provided with switch valve 10, 3rd end of aspiration pump three-way pipe 7 is connected with the air inlet end of aspiration pump aspiration pump 8, the top and bottom of aspiration pump flue dust collection tube 2 are equipped with static opening, and two aspiration pump static openings are connected with two aspiration pump test bars 4 respectively, and the central authorities of two aspiration pump test bars 4 are equipped with through hole, high temperature resistant heat insulation coating is scribbled in aspiration pump flue dust collection tube 2, organosilicon coating is scribbled in aspiration pump flue dust collection tube 2.
The principle of the invention is as follows:
Only make the solid in flue dust and gas, collection tube is entered with identical speed, the smoke sample that guarantee gathers is representative, the accuracy of the concentration of solid and gas in the flue gas that guarantee finally records, the present invention is provided with test bar 4 on flue dust collection tube 2, the static pressure in flue dust collection tube 2 is recorded by microbarograph 9, because of flue dust, to be inhaled into front and back temperature identical, gas density inside and outside flue dust collection tube 2 is equal, when the static pressure outside the static pressure in flue dust collection tube 2 and flue dust collection tube 2 is equal, the isokinetic sampling of gas and solid in flue dust can be realized.
Sampling flow process: bled by aspiration pump 8, atmospheric pressure enters the present invention by air collection tube 11, in pipeline, form negative pressure simultaneously, the size of this negative pressure, equal with flue dust collection tube 2 outer static pressure pressure reduction with static pressure in flue dust collection tube 2 is suitable, and now, flue dust is extracted by flue dust collection tube 2 from flue 1, fall in the first cyclone collector 5, the flue dust not dropping into the first cyclone collector 5 drops into the second cyclone collector 6.
