In the measurement and analysis of dioxins, unlike the general measurement and analysis of exhaust gas such as the measurement of smoke, in principle, the material of the exhaust gas sampling tube is made of glass. Sampling glass tube, other pitot tube for exhaust gas flow rate measurement,
Insert the gas sampling pipe for combustion gas component analysis and the gas sampling pipe for moisture measurement from the duct measurement hole, and the pitot tube for exhaust gas flow rate measurement is to measure the gas flow rate of the exhaust gas. It is said that the gas sampling pipe is used to grasp the combustion state of the incinerator.

Against this background, for the purpose of collecting dioxins in exhaust gas, combustion has been conventionally performed through a gap formed between a plurality of sampling pipes inserted through the duct measurement hole and the duct measurement hole. In order to prevent the exhaust gas generated by the above from leaking to the outside air, a method of covering and fixing with a heat-resistant cloth, asbestos or the like has been adopted.

For example, FIG. 1 is a perspective view showing a conventional exhaust gas collecting method, in which a dioxin collecting glass tube 1, an exhaust gas flow rate measuring pitot tube 2, a combustion gas component, Sampling pipes such as a gas sampling pipe 3 for analysis and a gas sampling pipe 4 for moisture measurement are appropriately inserted, and a duct measurement hole 11 where a sufficient space cannot be expected.
Alternatively, in the duct 12, mischievous collisions between a plurality of collection tubes can be expected. In particular, since the dioxin collection glass tube 1 is made of glass, there is a concern about breakage. Also, since multiple sampling tubes are inserted separately,
It becomes difficult to efficiently cover the gap formed between the duct measurement hole 12 and the plurality of sampling pipes. For this reason, it may not be possible to fix the pitot tube 2 for exhaust gas flow velocity measurement inserted in the duct 12 correctly in the vertical position, or the pitot tube may move during exhaust gas collection and become improperly fixed. Therefore, in such a method,
It is difficult to cover the gap between the collecting pipes well, and the individual collecting pipes may not be fixed properly and may move during exhaust gas collection, or may be damaged due to unreasonable contact between the collecting pipes, etc. Therefore, there has been a demand for a method capable of more reliably measuring and analyzing dioxins in exhaust gas.

Although dioxins are very toxic,
Because it is a substance that is considered to be present in the exhaust gas in a trace amount, in the collection of dioxins in the exhaust gas, a large amount of exhaust gas sampling is required in terms of the accuracy of dioxin measurement and analysis. ,
It is defined that gas suction should be performed at a constant velocity and the sampling gas amount should be 3 Nm 3 (4 hours average) or more in principle. During such a long period of exhaust gas sampling, it is required that the combustion state of the incinerator be stable, and from the meaning of this confirmation, it is necessary to continuously monitor the fluctuations of CO, CO 2 and O 2 concentrations in the combustion gas components. Analysis and measurement of water content every hour are obligatory, and when collecting dioxins in exhaust gas, insert the sampling pipes together from the duct measurement hole and sample the exhaust gas by the constant velocity suction method. It is necessary.

The conventional method of fixing a plurality of sampling pipes inserted through the duct measurement hole and the gap formed in the duct measurement hole by covering with heat-resistant cloth, asbestos, etc. is sufficient to stably fix the individual collection pipes. In addition, the flow rate measurement by the pitot tube for exhaust gas flow rate measurement, which is necessary for performing the exhaust gas suction and sampling by the accurate isokinetic suction method, the pitot tube may not be correct and may not be fixed stably. It was desired to improve the sampling of exhaust gas for dioxin measurement and analysis specified in the Ministry of Health and Welfare manual.

Further, if the pitot tube for measuring the exhaust gas velocity (hereinafter abbreviated as "Pitot tube") moves during exhaust gas collection, an appropriate exhaust gas velocity value cannot be obtained. It is preferable to install partition plates on the left and right. Here, there are two types of pitot tubes, a standard pitot tube usually called an L-shaped pitot tube and a special pitot tube usually called a western pitot tube. It has a structure in which two thin tubes are attached. In the flow rate measurement using a Western-type pitot tube, insert the pitot tube vertically at right angles to the flow direction of the exhaust gas from the duct measurement hole with the pitot tube placed vertically, and make the dynamic pressure measurement hole of the pitot tube face up in the flow direction of the exhaust gas. It is necessary to keep it fixed during collection. Accurately facing the pitot tube to the flow of exhaust gas means that the pitot tube is correctly fixed in the vertical position, but from the structure, the pitot tube is set in the vertical position without support. Therefore, in the fixture of the present invention, a partition plate for supporting the pitot tube for exhaust gas flow velocity measurement installed in the receiving portion from the left and right sides thereof is provided so that the pitot tube can be vertically installed. Thus, the sampling of the exhaust gas sample by the constant velocity suction method specified in the Ministry of Health and Welfare manual can be completed, and the pitot tube can be correctly installed.

FIG. 3 is an example of an overall view showing a state in which sampling tubes are installed on the fixture of the present invention.
Partition plates 5a and 5b for supporting the pitot tube 2 for measuring the exhaust gas flow rate from the left and right are provided on top of the partition plate, and the partition plate sandwiching the partition plate 5b and the glass tube 1 for dioxin collection. 5C shows a preferable state in the case where 5c is provided. In FIG. 3, a glass tube 1 for collecting dioxins and a pitot tube 2 for measuring the flow rate of exhaust gas are installed at the center of the receiving portion 6 via a partition plate 5b, and a gas sampling tube 3 for analyzing a combustion gas component and a moisture measurement. Gas sampling pipe 4
Are installed outside the glass tube 1 for collecting dioxins and the pitot tube 2 for measuring the flow rate of exhaust gas. For this reason, these collecting tubes are neatly arranged in a plane on the receiving part,
Furthermore, since each is separated by the partition plate, the sampling pipes do not collide with each other and are not damaged, and can be easily fixed to the duct measurement hole.

FIG. 4 is an example of a side view showing a state in which the fixture of the present invention is attached to the inside of the duct 12 and the cross section of the duct measurement hole 11. In FIG. 4, a pipe having an inner diameter slightly larger than that of the support column 7 in order to fix the support column 7 fixed to the support unit 6 and the flange unit 10 and to have a sliding function capable of moving the position of the support unit 6 up and down. 9 is applied to the column 7. In order to fix the column 7 and the pipe 9, the pipe 9 is provided with a screw 13. With this,
The strut 7 has a structure that passes through the pipe 9. The strut 7 in the pipe 9 can be slid as necessary, and is fixed with the screw 13, so that the height of the collection pipes installed in the receiving portion is increased. Adjustment is possible. In addition, a vice 8 is used to effectively fix the column 7 and the flange portion 10. When adjusting the height, a portion for fixing the flange portion 10 of the vise 8 and the screw 13 are opened and closed. Can be fixed at any position.
