As a result of analyzing the overall gas composition containing the collected gas and the attached gas, the results can be expected to be particularly improved in the analysis accuracy in the field of micro analysis. At the time of exhaust gas collection, in the state where an exhaust pipe or the like is provided, since the device for automatically cleaning the pipe is installed, the device for constructing the collecting pipe must have high convenience, and the collecting pipe is formed into a two-layer structure. Between the outer tube and the inner tube, a structure into which the cleaning liquid flows is set. In the collection pipe line, a fine hole for injecting the washing water is set. The exhaust pumping pump is used for extraction and can be recycled to the absorption bottle. Further, it can be constructed by pouring the washing water into the exhaust gas collecting pipe by the pump. Further, in the present invention, the collection can be carried out by designing conditions such as the position of the pore portion into which the washing water is injected, the amount of water, and the washing time. [Embodiment] Hereinafter, the present invention will be specifically described based on the embodiments shown in the drawings, and Fig. 1 is a conceptual view of an automatic measuring device according to the present invention. In addition, Fig. 2 is an enlarged view of a portion of the exhaust gas collection pipe. In the flue 1, the front end of the gas collecting pipe 2 is in contact with the exhaust gas 3, and this portion is a single pipe. Usually, the material of this gas collecting pipe is made of stainless steel which is resistant to exhaust gas. In addition, the diameter of the collecting pipe is about 5 mm. The collecting tubes 4 and 5 have a two-layer structure from the vicinity of the flange 7 on which the flue is installed toward the outside of the flue. The gas collection pipe 2 is connected to the absorption bottle 12 of the exhaust gas, and is connected to the pumping pump 14 and the gas flow meter 15. Thereafter, this figure omits an automatic analysis device for further connecting the sample water that automatically collects the absorbed exhaust gas components. Further, the inside of the double pipe structure portions 4, 5, that is, the structure in which the cleaning liquid is injected between the inner pipe and the outer pipe. The washing liquid is a structure in which the washing liquid is injected from the washing liquid inlet port 9 at the end of the double-tube structure portions 4 and 5 by washing 1275786. The gas collection method will be described. First, the exhaust pumping pump 14 is operated. Thereby, the extraction of the flue gas is started, and the exhaust gas passes through the exhaust gas collection pipe, and further absorbs the component to be analyzed as the gas absorption bottle 12, that is, in this case, the ammonia gas is absorbed, and after the reaction, the exhaust gas is discharged. The gas will be extracted again and discharged via a gas flow meter 15. After the exhaust gas collection is quantitatively performed, the pumping pump 14 is still maintained, and the cleaning liquid 13 is injected into the double-layer structure of the collecting pipe. The cleaning liquid passes through the double-tube structure portions 4, 5 between the inner tube and the outer tube, and the cleaning liquid is injected into the inner tube, that is, the inside of the gas collecting tube 2, from the fine hole 6 at the front end portion thereof. Due to the operation of the pumping pump 14, the cleaning liquid injected into the exhaust gas collection pipe will flow toward the gas absorption bottle and flow to the extraction direction, whereby the inside of the collection tube will be washed, washed and transferred to the inside of the tube. The ammonia component is stored in the absorption bottle. By performing the cleaning in the collection tube, ammonia can be recovered efficiently and surely. Further, the phenomenon occurring in the double-layer structure portion of the exhaust gas collection pipe is in the vicinity of the front end of the flue side of the double pipe, and is heated to 200 to 300 ° C in contact with the exhaust gas, and the initial stage of the injection liquid is injected. The washing liquid (in this case, pure water) is boiled in this part, and the boiled water vapor is extracted from the pores 6 toward the exhaust gas extraction direction, and is cooled to a liquid in the passing path, and is recovered to the absorption bottle. . Further, if the washing liquid is continuously injected, the entire double tube will be cooled' followed by a liquid state, and the washing liquid is injected from the fine holes 6. This cleaning solution is also recovered 1275786 Absorbent solution Boric acid solution 5g/l Boric acid solution 5g/l Boric acid solution 5g/l Boric acid solution 5g/l Absorbent volume 50 ml 50 ml 50 ml 50 ml Washing liquid volume about 150 ml Μ J \ M j \ \\ Approx. 100 ml Analytical sample solution volume 250 ml 250 ml 250 ml 250 ml Pre-analysis dust treatment membrane filter analysis ion chromatography [Table 2] High concentration range of experimental results Continuous test No. Continuous measurement Method Manual Analytical Method Continuous Measurement Method Method and Heating Method of the Invention Comparison of JIS Method and Manual Analysis Method Concentration A ppm Concentration B ppm AB ppm 1 Heating Method 1 109.0 122.0 -13.0 2 122.0 104.0 18.0 3 126.0 162.0 -36.0 4 109.0 92.0 17.0 5 115.0 136.0 -21.0 6 122.0 147.0 -25.0 7 121.0 131.0 -10.0 8 122.0 124.0 -2.0 9 Method 126.0 117.0 9.0 10 125.0 104.0 21.0 11 130.0 137.0 -7.0 12 132.0 115.0 17.0 13 132.0 121.0 11.0

Table 1 shows the individual exhaust gas collection conditions. The results of the experiments are summarized in Table 2, Table 3, Table 3, and Figure 4. Tables 2 and 3 are comparative experiments in the high NH3 concentration range of about I30 ppm, and the continuous test No. is used to avoid the experimental deviation as much as possible and continuously carry out the experiment. Further, the continuous measurement method was simultaneously measured with the manual analysis JIS method. Tables 3 and 4 show comparative experiments at a lower NH3 concentration range of I5 ppm. When the characteristics of each data are observed, it can be roughly understood that, in order to make it easier to understand, the difference between the continuous measurement method and the measurement method of the ns method as a reference is made into a histogram. They are Figure 5 and Figure 6, respectively. According to Fig. 5, in the high concentration range, the heating method is lower than the ns method, and it is inferred that a small amount of nH3 gas is not fully captured, but the continuous measurement method can obtain a stable result. The heating method 2 showed substantially the same enthalpy as compared with the JIS method, and it was considered that the effect of temperature increase was exhibited in comparison with the heating method. In addition, the method of the present invention shows a relatively high enthalpy relative to the JIS method, inferring that 1275786 NHS gas has been completely captured. Similarly, if the low concentration range of Fig. 6 is observed, the heating method 1 clearly shows low enthalpy. In addition, the method of the present invention also exhibits high enthalpy in a high concentration range. That is, it is known that the method according to the present invention is an excellent method from a range in which the gas concentration is high to a low range. [Effect of the Invention] As described above, according to the exhaust gas collection method of the present invention, the ammonia gas component concentration of the exhaust gas can be analyzed extremely accurately. Compared with the conventional method, according to the method of the present invention, as shown in Figs. 3 to 6, it is an excellent method, and this method is introduced into an automatic analyzer which continuously measures, thereby becoming an excellent automatic analyzer.
