Description
Technical Field
The utility model belongs to the technical field of sampling device, especially, relate to a single flue surveys hole multiple spot flue gas sampling device.
Background
In the smoke monitoring work, the basic principle of measuring hole positions and measuring point arrangement is that the measuring hole positions are arranged on the stable airflow section of the pipeline, and the vertical pipeline is considered preferentially. In principle, the distance between the position of the measuring hole and the elbow is at least the diameter of the flue when the requirement is difficult to meet, and the number of the side points is increased properly. When collecting gas pollutant samples, the position of the measuring hole is basically set at the stable section of the pipe airflow, and the air leakage part is avoided, and the sampling is carried out near the center of the pipeline.
In the prior art, a sampling gun used for sampling flue gas only has one gun rod extending into the interior for sampling analysis, the flue positions of different depths cannot be sampled simultaneously, and the sampling result is not representative, so that a single flue hole-measuring multipoint flue gas sampling device is provided.
SUMMERY OF THE UTILITY MODEL
The utility model provides a single flue survey hole multiple spot flue gas sampling device, aim at can perhaps carry out the analysis of taking a sample to the flue position of the different degree of depth in the flue survey hole simultaneously respectively.
In order to achieve the above object, the utility model adopts the following technical scheme:
a single flue hole-measuring multipoint flue gas sampling device comprises a plurality of sampling branch pipes with different lengths, wherein the sampling branch pipes are sequentially arranged side by side from long to short, two adjacent sampling branch pipes are tangent and welded, the outlet ends of the sampling branch pipes are converged to a main pipe, and the outlet ends of the sampling branch pipes are provided with valves; after the main pipeline is connected with the testing instrument, the sampling branch pipe is stretched into the flue, the on and off of the valve are controlled, and the sampling is carried out on different positions of the flue simultaneously or respectively.
Further, the sampling branch pipes and the main pipeline are all round pipes, and the pipe diameters of the sampling branch pipes are the same.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model discloses a weld a plurality of circular sample branch pipes together from long to short, make the sampler only a trunk line with the tail end intercommunication of sample branch pipe, connect test instrument through the trunk line to set up the on-off and the disconnected of valve control sample branch pipe at sample branch pipe exit end. The sampling device extends into the flue measuring hole, so that the flue positions at different depths can be sampled and analyzed simultaneously or respectively, the flue gas components at different positions of the flue can be tested at a single measuring point, or the mixed flue gas components at a plurality of measuring points can be tested, the test result is more representative, and the multi-point sampling is more convenient and quicker.
Drawings
Fig. 1 is a schematic structural diagram of a single flue hole-measuring multipoint flue gas sampling device.
Wherein: 1-sampling branch pipes; 2-a main pipeline; 3-valve.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The following is one of the embodiments of the present invention:
as shown in figure 1, a single flue survey hole multiple spot flue gas sampling device, including 3 different circular sample branch pipes of length 1, 3 sample branch pipes 1 arrange side by side and weld together according to the order from long to short in proper order, the exit end of sample branch pipe 1 communicates each other and assembles into a trunk line 2 (3 sample branch pipes promptly and with a trunk line 2), the exit end of every sample branch pipe 1 all is equipped with a valve 3 and controls the on or off of this sample branch pipe.
When in use, the main pipeline 2 is connected with a testing instrument, and the smoke components of a measuring point at the pipe orifice of the single sampling branch pipe 1 can be tested by opening the valve 3 corresponding to the sampling branch pipe 1; and simultaneously, the valves 3 of the 3 sampling branch pipes are opened, so that the mixed smoke components of the smoke at the measuring points at the pipe orifices of the 3 sampling branch pipes can be tested simultaneously. The flue gas sampling analysis is carried out on the flue positions of different depths simultaneously or respectively in one flue measuring hole, so that the test result is more representative, and the multipoint sampling is more convenient and quicker.
The preferred embodiments of the present invention disclosed above are intended only to help illustrate the present invention. The preferred embodiments are not intended to be exhaustive or to limit the invention to the precise embodiments disclosed. Obviously, many modifications and variations are possible in light of the above teaching. The embodiments were chosen and described in order to best explain the principles of the invention and its practical application, to thereby enable others skilled in the art to best understand and utilize the invention. The present invention is limited only by the claims and their full scope and equivalents.
