Description
Technical field
The invention belongs to the flue dust monitoring technical field in the environmental monitoring, more specifically relate to a kind of smoke dust sampling device of automatic position-finding point, it is applicable to the smoke dust sampling in the stationary pollution source.
Background technology
In flue, chimney and aiutage Concentration in Fixed Pollutants Source such as (hereinafter to be referred as flues), need be that flue dust is sampled to particle wherein, and measure other Gas Parameters simultaneously.The smoke dust sampling device is to carry out smoke dust sampling and the visual plant of measuring Gas Parameters.
When measuring Gas Parameters and sampling, in order to obtain representational sample, need the flue section be divided into the homalographic annulus or the square of right quantity, on the line that ring is divided into two homalographics or the square center as measuring point.The number of measuring point should be decided according to the size of flue and the shape of sampling section.When air-flow in the flue and grit skewness, the number of measuring point should be some more.
Before the smoke dust sampling, calculate the number of measuring point and the position of measuring point, make measuring point position mark with high temperature resistant adhesive plaster in the relevant position of the sampling pipe of smoke dust sampling device then according to the flue size of actual measurement.During smoke dust sampling; Sampling pipe is stretched into flue through the thieff hatch on the flue, and according to good measuring point position and the sampling time of calculating and setting before the sampling, the conversion measuring point is sampled successively; When needing the conversion spotting; The sample collector need shift to an earlier date tens of seconds and get ready, and the sampling pipe of when next point sampling begins, manually advancing and retreat rapidly begins the sampling of next measuring point to assigned address.
In the sampling process, owing to be the location, stable of manual operation sampling pipe, manual operation error such as occur easily that sampling pipe rocks and the speed of inclination, sampling pipe conversion advance and retreat is slow, the measuring point location is accurate inadequately causes the smoke dust sampling result to depart from actual value.Especially the location of measuring point, because the spacing of adjacent scale is 5cm on the general sampling pipe, when changing measuring point in the smoke dust sampling process, it is unlikely wanting quickly and accurately positioning error with sampling pipe to be controlled in the 1mm.
In the sampling process,, long-time manual operation sampling pipe to keep balance because the environmental baseline of spot sampling platform is abominable, not only arduous, also occur by accidents such as the sampling pipe of heat and thieff hatch scalds easily in the operating process.
The patent No. is that 200910249622.7 patent has been announced a kind of positioning ring of smoke dust sampling gun; Locating ring is fixed on the circular sampling pipe; Have view window can estimate the position-finding point, but the running fix of sampling pipe remains manually-operated, the error of artificial location is also bigger.
