Compared to prior art, in the utility model sampling apparatus, go out to have increased intelligent heating system at filtration unit, on the one hand, it can carry out the intermittence heating according to actual needs, guarantees the temperature of certain sample gas, avoid causing the detection deviation, and can prolong the mission life of described intelligent heating system, and avoid waste of electric energy simultaneously, reach the environmental protection and energy saving effect.In the described intelligent heater warning system is set simultaneously, when described intelligent heater breaks down and quits work, on operation interface, send alerting signal or produce certain alarm sound, so that allow the maintainer change or keep in repair described intelligent heater, described intelligent heater has higher reliability and convenience.
[description of drawings]
The structural representation of Fig. 1 the utility model sampling apparatus.
Fig. 2 is the structural drawing of the intelligent heating system of sampling apparatus.
Fig. 3 is the cross-sectional view of the line of III-III shown in 2 on the way.
[embodiment]
Through to existing CEMS systematic analysis, find that the heating system of sampling apparatus lost efficacy, mainly cause by following reason:
1, heating system does not have attemperating unit, causes heating-up temperature uncontrollable, simultaneously because the device of the automatic switching of the groundless temperature variation of heating system, causes heating system to work in 24 hours and has a strong impact on mission life;
2, the sampling heating system does not have autoalarm, and when quitting work when the heating system damage, the maintainer is difficult for finding, causes sample temperature to change, thereby influences test result.
For reason given above,, sampling apparatus is as shown in Figure 1 proposed through improvement targetedly,
Described sampling feeler lever 10 is made for gapless stainless steel tube, and the tested cigarette of tested chimney, dirt, gas are used for sampling.
Described filtration unit 20 comprises shell 21 and filter core 22.Described shell is that 21 metal stainless-steel tubes are made, and its inner filter core 22 is a ceramic element, is used for the impurity of sampling by filtration cigarette, dirt, gas.
Described sampling feeler lever 10 has an adapter 11 with described flange 30 connections.Described adapter 11 is made for machining, and adopts stainless steel or anticorrosion metal to make.Described sampling feeler lever 10 is connected with described flange 30 by described adapter 11.Described adapter 11 is embedded in the chimney body of wall 50.It should be noted that, the length of described adapter 11 is greater than the width of described chimney body of wall 50, thereby makes described adapter 11 parts, especially pad 15 places of itself and described sampling feeler lever 10, little being exposed to outside the chimney body of wall 50 prevents that described pad from being corroded by acid solution in the chimney body of wall.
For improve described adapter 11 anticorrosion effect, except adopting the higher stainless steel of antiseptic property, the thickness of described adapter 11 has also obtained suitable thickening, reaches more than the twice of a common transfer thickness, further improves its corrosion resistance.
Further, an anticorrosion spacer sleeve 12 is set in the outside of described adapter 11 (outer wall).Described anticorrosion isolation gum cover 13 is coated on the part that described adapter 11 is in the outer wall section in the described chimney body of wall 50 and forms pad fully, thereby stops acidic liquid to contact described adapter 11.Described anticorrosion spacer sleeve 12 can also adopt the anti-corrosion material of other materials except can adopting common ethene gum cover, can effectively prevent common soda acid, and described adapter 11 is effectively protected in the corrosion of example hydrochloric acid, nitric acid, sulfuric acid etc.Certainly can also suitably increase the thickness of described anticorrosion spacer sleeve 12, further strengthen anticorrosion isolation effect.
Further, because the temperature variation of sample gas mainly occurs in described filtration unit 20 places, in the present embodiment, special arranged outside one intelligent heating system 30 at described filtration unit 22.Described intelligent heating system 30 integral body are cylinder-like structure, are sheathed on the outside of described filtration unit 22, and slightly larger in diameter is in the diameter of described filtration unit 22, and length slightly is shorter than or equals the length of described filtration unit 22.30 pairs of described filtration units 22 of described intelligent heating system are incubated heating, and occurrence temperature changes when preventing sample gas through described filtration unit 22.
Concrete, please referring to Fig. 2 and Fig. 3, Fig. 2 is the structural drawing of described intelligent heating system, and Fig. 3 is the cross-sectional view of the line of III-III shown in 2 on the way.Described intelligent heating system 30 is the tubular double-decker, and its internal layer is a heater block 81, as resistive heater, electric dipole etc.
Outer for protecting fastening protective seam 82, its role is to: one, inner heater block 1 is protected; immobilizing foundation is provided simultaneously, and perforation A, perforation B and perforation C are set on described fastening protective seam 82; and in described perforation A, B, C, carry out the tapping setting, make things convenient for screw to fix.Certainly also can carry out more or less perforation as required, as long as can reach fixation.
The parameter of described intelligent heater 30 needs the parameter setting according to described filtration unit 22, and its canonical parameter is: the diameter of described heater block 81 is that the diameter of 76mm, described fastening protective seam 82 is 82mm.
Further, this intelligence heating system 30 is provided with temperature control system, can be according to the difference of the environment of actual detected, sample gas and intermittent work, to prevent over-heating, guarantee the temperature of certain sample gas, avoid causing the detection deviation, and can prolong the mission life of described intelligent heating system, avoid waste of electric energy simultaneously, reach the environmental protection and energy saving effect.
Further, in the described intelligent heating system 30 warning system is set, when described intelligent heater 30 breaks down and quits work, on operation interface, send alerting signal or produce certain alarm sound, so that allow the maintainer change or keep in repair described intelligent heater 30, the reliability of described intelligent heater 30 and maintainer's maintenance convenience have been improved from face.
Compared to prior art, in the utility model sampling apparatus, go out to have increased intelligent heating system at filtration unit, on the one hand, it can carry out the intermittence heating according to actual needs, guarantees the temperature of certain sample gas, avoid causing the detection deviation, and can prolong the mission life of described intelligent heating system, and avoid waste of electric energy simultaneously, reach the environmental protection and energy saving effect.In the described intelligent heater warning system is set simultaneously, when described intelligent heater breaks down and quits work, on operation interface, send alerting signal or produce certain alarm sound, so that allow the maintainer change or keep in repair described intelligent heater, described intelligent heater has higher reliability and convenience.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
