Abstract
The utility model discloses a flue gas mixer which comprises a shell, a plurality of air inlet pipes and an air outlet pipe, wherein a mixing cavity is formed in the shell, and the air inlet pipes are arranged on the same side of the shell in parallel; the air inlet pipes penetrate through the wall of the shell and extend to the inner part of the mixing cavity until reaching the front of the inner wall of the shell, and the air outlet pipe penetrates through the wall of the shell so as to convey mixed gas in the mixing cavity to a test instrument through a pipeline. The flue gas mixer carries out one-time measurement on flue gas components acquired for many times in the past, the mixed flue gas components is much closer to the flue gas components of the inner part of acquisition positions, an acquisition error and a measurement error are reduced, and the result is accurate. Meanwhile, the flue gas mixer has effects of reducing the measurement times and improving the working efficiency.
Description
Technical field
The utility model relates to power generation technical field, particularly relates to a kind of flue gas blender of measuring for flue gas.
Background technology
At present in the boiler of the industries such as electric power, the energy, power, chemical industry, environmental protection and the work such as performance test, emission test of auxiliary device (as air preheater, deduster, blower fan etc.), usually need the flue gas of privileged site to carry out sample analysis, be generally that probe tube is stretched in furnace wall smoke sampling, fume component analysis is the important content of boiler combustion and performance test.Generally will insert a probe tube in the uniform sample position of flue gas pressures, arrange some perforates on probe tube, position of opening is corresponding to concrete smoke sampling point.Flue gas enters probe tube by perforate, collects and cause measurement and analysis instrument by one end of probe tube in probe tube.
But, in the process of measuring now, gather respectively each point flue gas and then carry out respectively Measurement and analysis, causing starting at first measurement point and final measurement point, to differ the time long, the very large error of result existence of measurement.
Utility model content
The purpose of this utility model is for the technological deficiency existing in prior art, and a kind of flue gas blender that can effectively improve measurement result is provided.
For realizing the technical scheme that the purpose of this utility model adopts be:
A kind of flue gas blender, comprise inner housing, the multiple air inlet pipe that are set in parallel in housing the same side and an escape pipe that forms hybrid chamber, housing wall described in described air inlet pipe runs through also gos deep into described hybrid chamber inside and extends to the front termination of internal face of housing, and the housing wall described in described escape pipe runs through is to be delivered to tester by pipeline by the mixed gas in hybrid chamber.
Described hybrid chamber is the columnar structured of closed at both ends, and described air inlet pipe and escape pipe are all with the axially parallel of described hybrid chamber and be arranged on same bottom surface.
Described escape pipe is arranged on center, and described air inlet pipe and described escape pipe are equidistantly evenly arranged.
Described air inlet pipe and the outer end of escape pipe are pyramidal structure.
Described air inlet pipe and described hybrid chamber internal face spacing are 10-20mm.
Described air inlet pipe is 10-12, and it can mix the smoke components of maximum 12 thief hole collections and many groups flue gas be mixed and carries out flue gas analysis simultaneously.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is the smoke components one-shot measurement of multi collect in the past, measurement be smoke components after mixing, more approach the inner smoke components of collection place, reduce Acquisition Error and measure error, the result that is is more accurate.Have to reach simultaneously and reduce number of times, the effect of increasing work efficiency of measuring.
Brief description of the drawings
Figure 1 shows that structure schematic side view of the present utility model,
Plan structure schematic diagram shown in Fig. 2 shown in Fig. 1.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As Fig. 1, shown in 2, flue gas blender of the present utility model comprises that the inside of closed at both ends forms the housing 1 of cylindrical shape hybrid chamber, 10 are distributed on housing epipleural and are positioned at air inlet pipe 2 and the escape pipe 3 being arranged between two parties on housing 1 epipleural on same circumference, the epipleural of the housing described in described air inlet pipe runs through also gos deep into described hybrid chamber inside and extends to the front termination of lower side panel of housing, described air inlet pipe and described housing lower side panel internal face spacing are 10-20mm, preferably 15mm, epipleural center and the lower end, gas outlet of the housing described in described escape pipe runs through flush, by pipeline, the mixed gas in hybrid chamber is delivered to tester with housing epipleural inwall.Certainly, the shape of described housing is not limited to cylindrical shape, and it can be arbitrary shape, only need meet the condition that arranges of escape pipe and air inlet pipe.
Flue gas blender of the present utility model is setting up and down in use,, lower side panel at lower epipleural in upper vertical setting, described air inlet pipe lower end is goed deep into enclosure interior and is close to shell bottom, the inner water-filling of hybrid chamber in the process using, water level is in general 2/3rds positions of hybrid chamber, and being flue gas in order to make to be come in by air inlet pipe like this falls dust wherein and analyze unified being gathered by escape pipe in entering analytical instrument after the clearance spaces of hybrid chamber inside is fully mixed through water filtration.The smoke components that flue gas blender can be simultaneously collected 10(or 12 air preheater outlets or entrance sampling place mixes, and finally accumulates mixed flue gas through escape pipe and flow out.
This blender can carry out the flue gas of 10 samplings place mixed once and finally obtain the result that mist measures and approach the most the actual smoke components in flue, and what gather is 10 sample point flue gases of same time, make final result more accurately true.After using flue gas blender, will greatly reduce this error and greatly increase work efficiency, and being equivalent to the measurement of 10 times once to complete.
Further, described air inlet pipe and the outer end of escape pipe are pyramidal structure, the air inlet of blender and gas outlet are not simple cylindrical structurals, but Pagoda-shaped or taper shape, good seal when making flue gas turnover blender, specifically, in use procedure, can the flue gas of each sampling place be guided to air inlet pipe one by one by rubber hose, and mixed gas be sent to flue gas analysis instrument place with rubber tube.
The above is only preferred embodiment of the present utility model; it should be noted that; for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
