On equipped with temperature control electrical heating block；It is located at and have gas entrance on the sampling probe between cut-off pneumatic operated valve and forward flow filtering device；Institute
State the sample gas outlet on the end body contact body of sampling probe.
Wherein, the top of described straight cutting filtration core is also equipped with water proof and dust proof cover.
Wherein, the heating-up temperature of described temperature control electrical heating block is not less than 145 DEG C.
The beneficial effects of the utility model are:
1. around forward flow filtering core install temperature control electrical heating block it is ensured that flue gas to be analyzed enter sampling pipe after temperature
Will not reduce, it is to avoid moisture condensation situation occurs.
2. at direct insertion filtration core top, water proof and dust proof cover is installed, protects filtration core not to be subject to the dust in flue and water straight
Connect impact, it is to avoid blocking.
3. cut-off pneumatic operated valve connects low-pressure air and control chamber is demarcated in blowback, can achieve timing or the straight cutting of manual blowback front end
Formula filtration core, extends filtration core service life.
4. gas entrance connects gas electromagnetic valve and is followed by gas and blowback and demarcates control chamber so that gas warp at sampling probe
Enter meter calibration after over sampling pipeline and pretreatment, make sample gas and gas enter analysis meter with similarity condition, decrease
Systematic error.
Brief description
Fig. 1 is internal structure schematic diagram of the present utility model.
Fig. 2 is sampling flowsheet figure of the present utility model.
Specific embodiment
With reference to specific embodiments and the drawings, this utility model is expanded on further.
As shown in figure 1, a kind of electrical heating sampling probe demarcated with gamut with blowback, including sampling probe 1 and cladding
Housing 2 on sampling probe 1.
The front end of sampling probe 1 extend out to outside housing 2, is provided with straight cutting filtration core 3 in this end, straight cutting filtration core 3
Top is also equipped with water proof and dust proof cover 10.In use, direct insertion filtration core 3 stretches in process pipe, for guaranteeing to filter in-core
Water returns flue, and direct insertion filtration core 3 needs 15 leaning angles when installing, and water proof and dust proof cover 10 then needs back to pipeline
Interior airflow direction is installed, to guarantee that dust and water will not be directly impinging straight cutting filtration core.
Have low-pressure air entrance 4 on the sampling probe 1 in housing 2, during use, this low-pressure air entrance 4 is successively
External blowback electromagnetic valve 12 and pressurized gas cylinder 13, pass through low-pressure air after the pressurized gas tank of low-pressure air 13 and blowback electromagnetic valve 12
Entrance 4 enters in sampling probe 1.
Cut-off pneumatic operated valve 5 and forward flow filtering device 6 are sequentially arranged with the sampling probe 1 after this low-pressure air entrance 4.Its
In, cut-off pneumatic operated valve 5 is connected with the cut-off electromagnetic valve 11 outside housing 2, and low-pressure air is through cut-off electromagnetic valve 11 and cut-off pneumatic operated valve 5
Enter in sampling probe 1；Temperature control electrical heating block 7 is also equipped with forward flow filtering device 6, is used for guaranteeing that flue gas to be analyzed is entering
After probe, temperature will not reduce, it is to avoid moisture condensation situation occurs, and when using, the heating-up temperature of temperature control electrical heating block 7
It is not less than 145 DEG C.
It is located at and have gas entrance 8 on the sampling probe 1 between cut-off pneumatic operated valve 5 and forward flow filtering device 6, during use, should
The external gas electromagnetic valve 14 of gas entrance 8, low-pressure air enters in sampling probe 1 after gas electromagnetic valve 14.
Sample gas outlet 9 on the end body contact body 2 of sampling probe 1.
For improving the automaticity of this probe, aforementioned cut-off electromagnetic valve 11, blowback electromagnetic valve 12 and gas electromagnetic valve 14
