Abstract
This utility model provides a kind of differential pressure type feeler lever, and it includes outer tube and is nested in the inner tube of outer tube；One end tube wall of said inner tube is fixing with the tube wall of outer tube to be connected；It is outside that the other end tube wall of inner tube extends outer tube 1；The cavity of described outer tube connects formation sampling loop with the cavity of inner tube.This differential pressure type of the present utility model sampling feeler lever is particularly suited for flue gas desulfurization and denitration occasion uses, outer tube, inner tube form sampling loop, due to outer tube, inner tube aperture difference, pressure differential is formed outside between tube chamber and interior tube chamber during making gas sample, ensure that the unimpeded of sampling line, reducing pipeline blockage phenomenon, sampling time response is fast, it is ensured that DATA REASONING efficient, stable.
Description
Technical field
This utility model relates to environment monitoring device field, more particularly, it relates to a kind of sampling feeler lever.
Background technology
Flue gas monitoring system is a kind of the stationary source such as boiler, kiln to carry out continuous print, real-time tracking and measuring system
System, including gaseous contaminant monitoring subsystem, particle monitoring subsystem, Gas Parameters monitoring subsystem and data acquisition process
With communication subsystem.Gaseous contaminant monitoring subsystem is mainly used in monitoring concentration and the discharge of gaseous contaminant SO2, NOx etc.
Total amount.Sampling feeler lever is usually used in the smoke sampling in gaseous contaminant monitoring subsystem to fixed-contamination source emission, and it is arranged on
On flue or chimney, direct and smoke contacts, gather the gas of fixed-contamination source emission, and the sample gas collected is passed through
Sampling feeler lever is transported in other analytical equipments of flue gas monitoring system.Present smoke sampling feeler lever is single tube structure, often
Blockage phenomenon, makes the stability of DATA REASONING can not get ensureing.
Therefore, how to provide a kind of sampling feeler lever, to avoid sampling process blocks, and then improve stablizing of whole system
Property with sampling response speed, be current those skilled in the art's problem demanding prompt solution.
Summary of the invention
For achieving the above object, the following technical scheme of this utility model offer:
A kind of differential pressure type feeler lever, it includes outer tube 1 and is nested in the inner tube 2 within outer tube 1；One end of said inner tube 2
Tube wall is fixing with the tube wall of outer tube 1 to be connected；It is outside that the other end tube wall of inner tube 2 extends outer tube 1；The cavity of described outer tube 1 with
The cavity connection of inner tube 2 forms sampling loop.
Further, described outer tube 1 arranges stud 3, is used for connecting sampling probe.
Further, said inner tube 2 extends the part of outer tube 1, and front end is 45～90 ° of oblique angles or right angle.
The beneficial effects of the utility model are:
A kind of differential pressure type feeler lever of the present utility model is made up of nested outer tube, inner tube, and outer tube, inner tube are formed and sample back
Road, pipeline is not easily blocked, and sampling time response is fast, it is ensured that DATA REASONING efficient, stable.
Accompanying drawing explanation
Fig. 1 is this utility model one differential pressure type feeler lever structural representation.
In accompanying drawing: 1: outer tube；2: inner tube；3: stud.
Detailed description of the invention
In order to make those skilled in the art be more fully understood that the technical solution of the utility model, below in conjunction with of the present utility model
Accompanying drawing, carries out clear, complete description to the technical solution of the utility model, and based on the embodiment in the application, this area is general
Other similar embodiment that logical technical staff is obtained on the premise of not making creative work, all should belong to the application
The scope of protection.
A kind of differential pressure type feeler lever, it includes outer tube 1 and is nested in the inner tube 2 within outer tube 1；One end of said inner tube 2
Tube wall is fixing with the tube wall of outer tube 1 to be connected；It is outside that the other end tube wall of inner tube 2 extends outer tube 1；The cavity of described outer tube 1 with
The cavity connection of inner tube 2 forms sampling loop.In one preferred version, described outer tube 1 arranges stud 3, is used for connecting sampling
Probe.In order to easily facilitate sampling, said inner tube 2 extends the part of outer tube 1, and front end is 45～90 ° of oblique angles or right angle.
This differential pressure type of the present utility model sampling feeler lever is particularly suited for flue gas desulfurization and denitration occasion and uses, outer tube, interior
Pipe forms sampling loop, owing to outer tube, inner tube aperture are different, makes during gas sample outside between tube chamber and interior tube chamber
Forming pressure differential, it is ensured that sampling line unimpeded, reduce pipeline blockage phenomenon, sampling time response is fast, it is ensured that data are surveyed
That measures is efficient, stable.
Below this utility model is described in detail, the above, the only better embodiment of this utility model
, when not limiting this utility model practical range, the most all made impartial change according to the application scope and modified, all should still be belonged to
In this utility model covering scope.
