。Next, the operation will be explained. The air in the sampling pipe (2) is sucked by the suction pump (1), and the air is preheated by the heater (6) installed in the sampling pipe (2) path to lower the relative humidity and become similar to an iodine collector. After the dust in the air is removed by the dust filter (4), the activated carbon filter (5) has a collection efficiency of over 90% because the iodine or methyl iodide in the air lowers the relative humidity.
), and their radioactivity concentration is measured as radioactivity intensity by a scintillation counter (7).

It was necessary to prevent dew condensation on piping and equipment by heating the route to a temperature above the water dew point (for example, water i1 in the exhaust gas) at 0 VOL 96 to about 47° C. using a heater (62, etc.).

か得られない。In addition, in recent years, rubber products have increased in miscellaneous solid incineration materials, and the concentration of sulfur oxides (SOx) in the exhaust gas has increased from several ppm to a maximum of 500 ppm, raising the acid dew point of the exhaust gas and
Sulfuric acid dew point corrosion in which 8 condenses as sulfuric acid and corrodes the mesh (normally, the water dew point of exhaust gas that does not contain SO8 and contains H and O around loVOL% is around 50°C, but SO3
The acid dew point of the exhaust gas is 15
) becomes a problem, and the exhaust gas temperature is reduced to 18
The temperature had to be 0°C or higher, and the activated carbon filter (6) was also required to collect 90% or more of iodine or methyl iodide at 180°C. The material used for the activated carbon filter (5) is carbon impregnated with 10 wt% TEDA due to its collection performance and price.However, at 180°C, the impregnated triethyldiamine (TEDA) evaporates from activated carbon, so activated carbon is not impregnated carbon. Therefore, the collection mechanism for iodine or methyl iodide is only physical adsorption rather than chemisorption, and desorption is likely to occur due to the high exhaust gas temperature, and the collection efficiency for methyl iodide is approximately 25%.
% (experimental results) and only a low value is obtained for the target of 90% or more.

→It may be possible to remove corrosive components in the exhaust gas in the form of a condensed aqueous solution (dilute hydrochloric acid, dilute sulfuric acid, and dilute nitric acid) by cooling the exhaust gas to approximately 10'0 (below the water dew point), but this will cause the iodine to become dusty. There were problems such as the loss of representativeness as a sample because the sample was deposited on the inner surface of the cooler.

The object of the present invention is to obtain an iodine measuring device that uses an inexpensive and marketable activated carbon filter such as a 10 wt % activated carbon filter impregnated with phosphorous and has a collection efficiency of 90% or more.

で測定される。The incinerator exhaust gas in the sampling pipe (2) is sucked by the suction pump (1), and the incinerator exhaust gas is heated to a sulfuric acid dew point of C, for example, 503% in the exhaust gas by the heater (6) installed in the sampling pipe (2) path. m! lK 350pp
m 1 When the amount of water gas in the exhaust gas is 10VOL%, it is kept at a temperature of 180"C or higher (approximately 165℃) to prevent acid condensation, and then enters the iodine collector with integrated heat exchanger (3). As a result, it is incinerated. Furnace exhaust gas is cooled by heat exchange between the cooling circulating water heated to 60-90°C and the first half of the heat exchanger-integrated iodine collector (3).
After dust is removed by a dust filter (4), iodine or methyl iodide is collected by an activated carbon filter (5), and the strength of the radioactivity is measured by a scintillation counter (7).
It is measured in

率９０％以上が確保できる。According to the above, since the incinerator exhaust gas temperature is kept at iso°C until it enters the integrated heat exchanger type iodine collector (3), acid condensation does not occur in the sampling pipe (2).
The representativeness of the sample through sampling is protected. In addition, the first half of the integrated heat exchanger type iodine collector (3) cools the incinerator exhaust gas temperature to 60 to 90°C, and passes it through an activated carbon filter (5 mm) in the temperature range with published performance data, so the collection efficiency is improved. More than 90% can be secured.

蒸気を吸湿して硫酸水溶液のなる。In addition, since the first half of the heat exchanger-integrated iodine collector (3) cools the incinerator exhaust gas temperature to 60 to 90°C, it becomes higher than the water dew point (for example, about 47°C when the water content in the exhaust gas is 10VOL%).
It is not possible to form a coagulated aqueous solution of hydrochloric acid or nitric acid, but the acid dew point is approximately 16.
Sulfuric acid at a temperature as high as 5°C condenses and absorbs water vapor in the exhaust gas, forming an aqueous sulfuric acid solution.

施している。The condensation rate of this sulfuric acid aqueous solution is approximately 0.7% in exhaust gas with a water content of 10VOL% (for example, the S03 concentration in exhaust gas is 35%).
Assuming that sulfuric acid with a concentration of 6096 condenses at 0 ppm and a metal surface temperature of 80''C, the total pressure of the sulfuric acid aqueous solution is approximately 76 KHg =
10 VOL% water vapor partial pressure. ) and the amount of N condensation that impairs the representativeness of the sample, and since the iodine collector + 31 with integrated heat exchanger is installed vertically, the condensed sulfuric acid aqueous solution is
When the amount exceeds a certain level, it is dripped and adsorbed by the activated carbon filter (6), so the deposition rate is further reduced and the representativeness of the sample is protected. Note that the exhaust gas portion of the heat exchanger-integrated iodine collector (3) is coated with Teflon for corrosion resistance.
