Description
Technical field
Pretreatment system in extraction-type particulate matter on-line monitoring system of the present invention, belongs to extraction-type particulate matter on-line monitoring
Technical field.
Background technology
For extraction-type dust instrument, flue gas（Sample gas）Pretreatment serve key effect, pretreating effect it is good
It is bad, directly influence the degree of accuracy of measurement result.And pretreatment system need solve two technological difficulties, first, remove smoke
Influence of the middle vapor to measurement, second, prevent greater particle size particulate matter from being polluted to the optical lens of measuring system.The
Three：System is not under open state, etching problem of the flue gas to system in flue.
The content of the invention
The invention overcomes the deficiencies of the prior art, and provides in a kind of extraction-type particulate matter on-line monitoring system
Pretreatment system, by pretreatment, improves the degree of accuracy measured particulate matters such as flue gases.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：Extraction-type particulate matter on-line monitoring system
In pretreatment system, including the first heating module, the second heating module, the 3rd heating module, magnetic valve and measuring chamber are described
First heating module is arranged on sampling probe, and the temperature for quickly improving sampling flue gas, second heating module is set
On pipeline between sampling probe and measuring chamber, for the flue gas for continuing to heat to come from sampling probe, the 3rd heating
Module is arranged on measuring chamber, and for ensuring that the flue-gas temperature in measuring chamber is higher than dew-point temperature, the magnetic valve is arranged on survey
Amount room is entered on the pipeline of fume side, the measuring chamber top and pipeline communication, the bottom connection flue gas exhaust pipe of the measuring chamber,
It is horizontally disposed in the measuring chamber to have optical measurement.
The magnetic valve is normally close valve.
The present invention has an advantageous effect in that compared with prior art：The present invention uses three-level flue gas technology, solves
Influence of the middle vapor to measurement that remove smoke；Using measuring chamber feature optical camera lens backwashing technology, solve prevent compared with
Large-size particles thing is polluted to the optical lens of measuring system, using preposition normally closed solenoid valve technology, solves system not
Under open state or unexpected powering-off state, etching problem of the flue gas to system in flue.The invention enables whole measuring system fortune
Row is stable, and measurement is accurate, cleans for a long time with self-protection function and without the optical component to measuring system.
Brief description of the drawings
The present invention is described further below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the invention.
Fig. 2 is side view of the invention.
Fig. 3 is the structural representation of measuring chamber in the present invention.
In figure：1 it is the first heating module, 2 be the second heating module, 3 be the 3rd heating module, 4 be magnetic valve, 5 is survey
Amount room, 6 be flue gas exhaust pipe, 7 be optical measurement.
Embodiment
As shown in Figure 1, Figure 2 and Figure 3, the pretreatment system in extraction-type particulate matter on-line monitoring system of the present invention, including
First heating module 1, the second heating module 2, the 3rd heating module 3, magnetic valve 4 and measuring chamber 5, first heating module 1
Be arranged on sampling probe, for quickly improve sampling flue gas temperature, second heating module 2 be arranged on sampling probe with
On pipeline between measuring chamber 5, for the flue gas for continuing to heat to come from sampling probe, the 3rd heating module 3 is arranged on
On measuring chamber 5, for ensuring that the flue-gas temperature in measuring chamber 5 is higher than dew-point temperature, the magnetic valve 4 is arranged on measuring chamber 5 and entered
On the pipeline of fume side, the top of measuring chamber 5 and pipeline communication, the bottom connection flue gas exhaust pipe 6 of the measuring chamber 5, institute
Stating horizontally disposed in measuring chamber 5 has optical measurement 7.
The magnetic valve 4 is normally close valve.
The present invention takes the mode of three-level heating, first for influence problem of the middle vapor to measurement that remove smoke
Level is heated to be sampling probe heating, improves sampling flue-gas temperature to quick, the second level is heated to be heat tracing pipe heating, in one-level plus
On the basis of heat, continue to improve flue-gas temperature, the third level is heated to be measuring chamber heating, is ensuring the flue-gas temperature into measuring chamber
On the premise of dew-point temperature, the measurement of flue gas particles concentration is completed.
The present invention is for preventing greater particle size particulate matter from polluting problem to the optical lens of measuring system, mainly from survey
Start with terms of amount cell structure, greater particle size particulate matter is big due to weight, into after measuring chamber, can decline under gravity, fall
Fall in measuring chamber bottom, therefore the optical component of measuring system will avoid being placed on measuring chamber bottom, it is of the invention by measuring chamber water
Plain cloth is put, and flue gas enters measuring chamber by upper interface, then flows out measuring chamber by lower interface, and two interfaces are perpendicular at one
On vertical line, now the signal detection with optical component is partially disposed on the left of measuring chamber, greater particle size particulate matter is just may be such that
It will not fall on optical component.
The present invention under system not open state or unexpected powering-off state, in flue flue gas to the etching problem of system,
The front end pre-processed in flue gas sets normally close valve, in the case of system closedown or suddenly power-off, pre-processes the electromagnetism of front end
Valve is in flue gas in normally off, completely isolated flue, it is cannot be introduced into dust instrument measuring system, serves protection system
Effect.
Embodiments of the invention are explained in detail above in conjunction with accompanying drawing, but the present invention is not limited to above-mentioned implementation
Example, in the knowledge that those of ordinary skill in the art possess, can also make on the premise of present inventive concept is not departed from
Go out various change.
