Description

A kind of grid multidraw system for the monitoring of multiphase flow medium composition
Technical field
This utility model is related to a kind of grid multidraw system for the monitoring of multiphase flow medium composition, and which is mainly suitable for Sample and its component analyses detection in multiphase flow medium.
Background technology
Traditional coal-burning boiler Dual-Phrase Distribution of Gas olid sampling, using single-point type sampler, and the sampling of multiple single-point combination types. As the section of pipeline section is larger, there is larger sampling blind area, and gas-solid with the sampling of multiple single-point combination types in single-point type sampling In the pipeline section of two streams, the velocity of medium in each region is different, causes sampling deviation very big and samples without representativeness.
The content of the invention
For the problem for overcoming above-mentioned prior art to exist, this utility model provides a kind of for multiphase flow medium composition prison The grid multidraw system of survey.
This utility model is adopted the technical scheme that:A kind of grid multidraw system for the monitoring of multiphase flow medium composition System, which includes pipeline for sampling, the filtration that is connected with the sampler of some samplers in the pipeline Device, the outlet connection temperature control heat tracing pipeline of the filter, connection measures entering for air chamber to the temperature control heat tracing pipeline respectively simultaneously The outlet of mouth and air heater, the entrance of the air heater connect source of the gas by pipeline, connect on the measurement air chamber There is air extractor.
Preferably, it is described for sampling pipeline be divided into some sections of territory elements, be provided with each section of territory element to A few sampler, each sampler are provided with least one sampling mouth.
Preferably, a sampler is provided with each section of described territory element, each sampler is provided with least three Sampling mouth, each sampling mouth are uniformly distributed on sampler.
Preferably, the air inlet pipeline of the air heater is provided with compressed-air filter, compressed-air filter Porch is provided with valve.
Preferably, the measurement air chamber connection medium composition analyser, medium composition analyser simultaneously also with control on the spot Cabinet connects.
The beneficial effects of the utility model are:
This utility model changes conventional point sampler and samples without representativeness, and sampling there is blind area and deviation is asked greatly Topic, this multi-point grid formula sampler allow using more they tend to it is reasonable with it is accurate, while this utility model can according to client's needs, access The such as analysis meter such as CO, O2, NOX, SO2, can order or multiple instrument monitor simultaneously.
This utility model is provided with more than 1 on every group of sampler and samples mouth, and multigroup sampling is gone to be applied in combination, and takes How much sample device quantity is determined by flue zoning.Flue region is divided using equal-area method, both can guarantee that samples' representativeness Again can eliminate the blind area for sampling, allow sampling more they tend to it is reasonable with it is accurate.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure:1- samplers, 2- filters, 3- temperature control heat tracing pipelines, 4- measurement air chambers, 5- medium composition analysers, 6- Air extractor, 7- on-site controls, 8- air heaters, 9- compressed-air filters, 10- pipelines.
Specific embodiment
This utility model is described in detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of grid multidraw system for the monitoring of multiphase flow medium composition, which is included for sampling Pipeline 10, some samplers 1 in the pipeline 10, the filter 2 being connected with the sampler 1, the filtration The outlet connection temperature control heat tracing pipeline 3 of device 2, connection measures the entrance and air of air chamber 4 to the temperature control heat tracing pipeline 3 respectively simultaneously The outlet of heater 8, the entrance connection source of the gas of the air heater 8, is connected with air extractor 6 on the measurement air chamber 4.
In this utility model, sampling pipe sectional area is divided equally using equal-area method, and is divided into multiple territory elements, often At least one sampler 1 is provided with one section of territory element, and each sampler 1 is provided with least one sampling mouth.Sampler is to wearing Flue, is fixed using flange.
When sampling, air extractor 6 produces certain suction by the power of itself to measuring air chamber 4, makes institute in pipeline 10 Medium to be sampled is filtered into filter 2 through multi-point sampling device 1, then Jing temperature control heat tracings pipeline 3 reaches measurement air chamber 4, so Enter data between electronics after the measurement of medium composition analyser 5 analysis afterwards.Meanwhile, air extractor 6 is located at measurement air chamber 4 and pipeline Between 10 constitute a loop, measure air chamber 4 in sample gas can Jing air extractors 6 return in pipeline 10.
Additionally, compressed-air filter 9 is provided with the air inlet pipeline of the air heater 8, compressed-air filter 9 Entrance connection compressed gas source(Using power plant's compressed gas source), and porch is provided with valve.When blowback, compressed gas source Into after compressed-air filter 9, air inlet heater 8, entering high temperature heat tracing pipeline 3 or filter 2 after heating is carried out instead Purging, to prevent filter and pipeline blockage, while compressed-air filter leaches moisture and greasy dirt in compressed air, prevents Equipment pipeline blockage.
In this utility model, the sample gas of sampler suction is filtered by filter, can be removed solid particulate matter, be prevented right Medium composition analyser below produces interference.In addition, whole pipeline temperature control heat tracing, can be with waterproof moisture condensation, blocking pipeline. It is suction power source using air extractor, using power plant's compressed gas source, without driven by power, suction is stable, and long service life is led to Overregulate air extractor and be capable of achieving average rate sampling.Simultaneously according to field condition arrangement scene with regard to cabinet, and design according to outdoor cabinet Require, integrated control unit is in cabinet.
Ultimate principle of the present utility model, principal character and advantage has been shown and described above.The ordinary skill of this area Personnel are not it should be appreciated that above-described embodiment limits protection domain of the present utility model, all employing equivalents etc. in any form The technical scheme obtained by mode, falls within protection domain of the present utility model.
This utility model is not directed to partly same as the prior art or can be realized using prior art.
