Abstract
The utility model discloses a gridLayout multidraw ware, including sample pipeline section (1), its characterized in that: sample pipeline section (1) in be equipped with a plurality of sample mouths (2), a plurality of sample mouths (2) component gridLayout structure in sample pipeline section (1) on the same cross -section of sample pipeline section (1). The utility model discloses a a plurality of sample mouths that to take a sample on the same cross -section of pipeline section constitute the gridLayout structure in the sample pipeline section, it is regional specifically to be that adoptions waits area method gridLayout to divide under every sample mouth, simultaneously through set up at least three sample mouth on every sampling tube and make up the use with a plurality of sampling tubes for the samples' representativeness can be guaranteed to this sampler can eliminate the blind area of sample again, lets the sampling more tend to reasonable and accurate.
Description
Technical field
This utility model relates to a kind of grid type multi-point sampling device, and this grid type multi-point sampling device is applicable to coal-burning boiler gas-solid two stream sampling.
Background technology
Traditional coal-burning boiler gas-solid two stream sampling, adopts single-point type sampler and the sampling of multiple single-point combination type.Owing to the cross section of pipeline section is relatively big, there is bigger sampling blind area in single-point type sampling and the sampling of multiple single-point combination types, and in the pipeline section of gas-solid two stream, the velocity of medium in each region is different, causes sampling deviation very big and sampling is without representative.
Summary of the invention
The purpose of this utility model is for prior art Problems existing, it is provided that a kind of adopt equal-area method grid type divide each sampling mouth affiliated area with dead zone-eliminating, allow sampling tend to rationally with grid type multi-point sampling device accurately.
The purpose of this utility model solves by the following technical programs:
A kind of grid type multi-point sampling device, including sampling pipeline section, it is characterised in that: being provided with multiple sampling mouth in described sampling pipeline section, the multiple sampling mouths on the same cross section of sampling pipeline section constitute grid structure in sampling pipeline section.
The same cross section of described sampling pipeline section adopts equal-area method to be divided into multiple territory element, and sampling mouth is positioned at the center of above-mentioned zone unit.
Described sampling pipeline section is provided with and is perpendicular to the probe tube that sampling pipeline section is arranged, and is positioned at the sampling mouth that same is perpendicular on the straight line of sampling pipeline section and is arranged on same probe tube.
The outlets organizing probe tube are connected with same flow pipe more so that the medium sampled in sampling pipeline section enters through over sampling mouth and enters in sampling container then through flow pipe after probe tube.
Same probe tube is provided with at least three sampling mouth and the combination of multiple probe tube uses.
This utility model has the following advantages compared to existing technology:
This utility model by constituting grid structure by the multiple sampling mouths on the same cross section of sampling pipeline section in sampling pipeline section, equal-area method grid type is specifically adopted to divide each sampling mouth affiliated area, simultaneously by arranging at least three sampling mouth on each probe tube and the combination of multiple probe tubes being used, change the sampling of conventional point sampler and there is blind area and the big problem of deviation without representative and sampling, make this sampler not only can guarantee that samples' representativeness but also the blind area of sampling can be eliminated, allow sampling more they tend to reasonable and accurate.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Wherein: 1 sampling pipeline section；2 sampling mouths；3 probe tubes；4 flow pipe.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, this utility model is further described.
As shown in Figure 1: a kind of grid type multi-point sampling device, including sampling pipeline section 1, it is provided with multiple sampling mouth 2 in sampling pipeline section 1, multiple sampling mouths 2 on the same cross section of sampling pipeline section 1 constitute grid structure in sampling pipeline section 1, the same cross section of sampling pipeline section 1 adopts equal-area method to be divided into multiple territory element, and sampling mouth 2 is positioned at the center of above-mentioned zone unit；Additionally it is provided with on sampling pipeline section 1 and is perpendicular to the probe tube 3 that sampling pipeline section 1 is arranged, be positioned at same be perpendicular to sampling pipeline section 1 straight line on sampling mouth 2 be arranged on same probe tube 3, same probe tube 3 is provided with at least three sampling mouth 2 and multiple probe tube 3 combination uses, the outlets organizing probe tube 3 are connected with same flow pipe 4 more so that the medium sampled in sampling pipeline section 1 enters through over sampling mouth 2 and enters in sampling container then through flow pipe 4 after probe tube 3.
When grid type multi-point sampling device of the present utility model uses, produce negative pressure by external pumping force so that the medium sampled in sampling pipeline section 1 enters through over sampling mouth 2 and enters in sampling container then through flow pipe 4 after probe tube 3, to reach sampling purpose.
This utility model by constituting grid structure by the multiple sampling mouths 2 on the same cross section of sampling pipeline section 1 in sampling pipeline section 1, equal-area method grid type is specifically adopted to divide each sampling mouth affiliated area, simultaneously by arranging at least three sampling mouth 2 on each probe tube 3 and multiple probe tubes 3 being combined use, change the sampling of conventional point sampler and there is blind area and the big problem of deviation without representative and sampling, make this sampler not only can guarantee that samples' representativeness but also the blind area of sampling can be eliminated, allow sampling more they tend to reasonable and accurate.
Above example is only explanation technological thought of the present utility model; protection domain of the present utility model can not be limited with this; every according to the technological thought that the utility model proposes, any change done on technical scheme basis, each fall within this utility model protection domain；The technology that this utility model is not directed to all can be passed through prior art and be realized.
