Abstract
The utility model relates to a smoke gas sampling pipe, which has the advantages that the flow rate of smoke gas entering each sampling hole can be uniform and constant for representing the average level of the sampling pipe positions so that the flow rate of the smoke gas of analysis instruments collected from each sampling point can be uniform and constant. The smoke gas sampling pipe structurally comprises a smoke gas mixer, wherein one end of the smoke gas mixer is connected with a plurality of concentrically nested round pipes, and the other end of the smoke gas mixer is a lead-out end.
Description
Technical field
The utility model relates to a kind of gas sampling probe.
Background technology
At present in work such as the performance test of the boiler of industries such as electric power, the energy, power, chemical industry, environmental protection and auxiliary device (as air preheater, fly-ash separator, blower fan etc.), emission test, usually need the flue gas of privileged site is carried out sample analysis, generally be that stopple coupon 2 is stretched in the furnace wall 1 smoke sampling, see shown in Figure 1.Fume component analysis is the important content of boiler combustion and performance test.Generally will insert a stopple coupon in the uniform sample position of flue gas pressures, arrange plurality of opening on stopple coupon, position of opening is corresponding to concrete smoke sampling point.Flue gas enters stopple coupon by perforate, compiles in stopple coupon and causes measurement and analysis instrument by an end of stopple coupon, sees shown in Figure 2.
Among Fig. 2, it has stopple coupon 2, and stopple coupon 2 is connected with plug 4, is provided with a plurality of through hole 3(and often adopts φ 2 on stopple coupon 2), through hole 3 correspondence positions are the collection point of flue gas.Flue gas is confluxed to stopple coupon by each through hole 3, shown in arrow among Fig. 2.By the law-analysing of gas flow as can be known, enter the flue gas flow of the flue gas flow of first through hole 3＜enter second through hole 3＜the enter flue gas flow of third through-hole 3, this is the result that the pressure difference of the each point that flow of flue gas causes in the pipe is caused.Because enter the flow difference that each flue gas is gathered the hole, under each sampling spot place gas componant distributes different situations, just may bring the deviation of measurement result.
Summary of the invention
The purpose of this utility model is exactly in order to address the above problem, provide a kind of and can make the flue gas flow uniformity that enters each thief hole, representing the average level at stopple coupon position, thereby make the gas sampling probe that collects the flue gas flow uniformity of analytical instrument from each sampling spot.
For achieving the above object, the utility model adopts following technical scheme:
A kind of gas sampling probe, it comprises the flue gas mixer, and flue gas mixer one end connects the pipe of a plurality of nested, concentric, and the flue gas mixer other end is an exit.
Described flue gas mixer front end is cylindrical, and the rear end is an infundibulate.
Stopple coupon of the present utility model is made up of a plurality of pipe nested, concentric, and an end of pipe is the flue gas sampling point, and the other end is connected to the flue gas mixer, and the flue gas mixer is a convergent shape to the stopple coupon exit, makes flow of flue gas more smooth and easy.Can make the flue gas flow of each sample position inflow stopple coupon identical by the diameter combination of selecting pipe.
The pressure reduction that each smoke sampling of stopple coupon of patent design is put mixer is identical, and the resistance of pipe, donut depends on the diameter and the length of pipe or form the diameter and the length of two pipes of annulus.The length of each pipe can make the flue gas flow of each sample position inflow stopple coupon identical by the sample position decision of design by the diameter combination of selecting pipe.
The beneficial effects of the utility model are simple in structure, and are easy to use, can guarantee the flue gas flow uniformity.

Fig. 2 is existing stopple coupon structural representation.
Fig. 3 is a stopple coupon structural representation of the present utility model.
Wherein, 1. furnace wall, 2. stopple coupon, 3. through hole, 4. plug, 5. mixer, 6. exit, 7. pipe.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Among Fig. 3, it comprises flue gas mixer 5, and flue gas mixer 5 one ends connect the pipe 7 of a plurality of nested, concentric, and flue gas mixer 5 other ends are exit 6.
Described flue gas mixer 5 front ends are cylindrical, and the rear end is an infundibulate.
Claims (2)
1. a gas sampling probe is characterized in that, it comprises the flue gas mixer, and flue gas mixer one end connects the pipe of a plurality of nested, concentric, and the flue gas mixer other end is an exit.
2. gas sampling probe as claimed in claim 1 is characterized in that, described flue gas mixer front end is cylindrical, and the rear end is an infundibulate.
