Embodiment 1

[0060] Used as a breathable sheet with a specific surface area of ​​700m 2 Flakes of 1.5 g of coal tar pitch-based fibrous activated carbon per gram were used to manufacture the capture body 7 related to the above-mentioned embodiment, and use it to make the collection device 1 related to the above-mentioned embodiment. Wherein, the size of the capture body is set to be 12 mm in inner diameter, 19 mm in outer diameter and 120 mm in length.

[0061] Using this collection device, gas samples were collected from the flue of an incineration facility that was incinerating waste. At this time, the collection method of the gas sample is carried out according to the collection method of the gas sample stipulated in the above-mentioned "Guidelines for the Standard Measurement and Analysis of Dioxins in Waste Disposal". Quantitative analysis of chlorinated organic compounds (dioxins) collected by this collection device, the result is the same as that of the conventional method specifie...

Embodiment 2

[0062] Made as a capture body will contain a specific surface area of ​​1000m 2 Coal tar pitch fibrous activated carbon 0.8g air-permeable paper-like body rolled into a cylindrical shape with an inner diameter of 15mm, an outer diameter of 17mm and a length of 120mm, and one end is closed (as the inorganic fiber contains microglass fiber. in the form of scheme (3)). Using this capture body instead of the capture body used in Example 1 above, a collection device similar to Example 1 above was produced. Using this collection device, the quantitative analysis of chlorinated organic compounds (dioxins) was carried out in the same manner as in Example 1, and the same analysis results as in Example 1 were obtained as expected. Example 3

Embodiment 3

[0063] Appropriate mixing specific surface area 100m 2 / g of coal tar pitch-based fibrous activated carbon and micro-glass fiber, and then add cellulose-based binder as a binder component to form. Therefore, the outer diameter 19mm of the open end side, the outer diameter 18mm of the closed end side, the thickness 5mm and the length 120mm are respectively set, and what contains fibrous activated carbon 3.0g, the capture body 17 related to the above-mentioned other embodiment (5). Using the obtained capture body instead of the capture body used in the above-mentioned Example 1, a collection device similar to that of the above-mentioned Example 1 was produced. Using this collection device, the quantitative analysis of chlorinated organic compounds (dioxins) was carried out in the same manner as in Example 1, and the same analysis results as in Example 1 were obtained as expected.

Abstract

A collector is provided which is capable of simultaneously capturing and collecting particulate and gaseous chlorinated organic compounds contained in a fluid. The collector 3 includes a housing 6 and a captor 7 disposed within the housing 6. The captor 7 includes a tubular porous core member 7a of a sintered glass having one end closed with a close member 7c, and a gas-permeable sheet 7b fitted around the core member 7a. The gas-permeable sheet 7b is, for example, a paper-like sheet having a fibrous activated carbon and inorganic fibers. The particulate and gaseous chlorinated organic compounds contained in a gas sample flowing into the captor through a sampling tube 2 are simultaneously collected and removed from the gas sample by the core member 7a and the gas-permeable sheet 7b, and the gas sample free from the chlorinated organic compounds is then discharged from an outlet port 6b.

Description

technical field [0001] The present invention relates to a collector for chlorinated organic compounds, in particular to a collector for collecting chlorinated organic compounds contained in fluids. technical background [0002] Chlorinated gases such as dioxins, polychlorinated biphenyls (PCBs), chlorophenols, and chlorobenzenes are contained in exhaust gases from incineration facilities that incinerate industrial waste and general household waste. organic compounds. [0003] Here, dioxins are polychlorinated biphenyl·p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDF s ) etc., are well-known highly toxic environmental pollutants, among which, especially dibenzodioxin tetrachloride (T 4 CDDs), recognized as the most toxic substances. On the other hand, although the toxicity of chlorinated organic compounds such as polychlorinated biphenyls, chlorophenols, and chlorobenzenes is weaker than that of dioxins, under certain conditions, for exampl...
