Example Embodiment

[0059] Hereinafter, the present invention will be explained in more detail through examples. Example 1

[0060] Used as an air-permeable sheet with a specific surface area of ​​700m 2 A flake of 1.5 g of coal pitch-based fibrous activated carbon was produced to produce the capture body 7 according to the above-mentioned embodiment, and the collecting device 1 according to the above-mentioned embodiment was made using it. Among them, the size of the capture body is set to an inner diameter of 12 mm, an outer diameter of 19 mm, and a length of 120 mm.

[0061] Using this collection device, gas samples are collected from the flue of an incineration facility that is incineration of waste. At this time, the gas sample collection method is implemented in accordance with the gas sample collection method specified in the aforementioned "Guidelines for the Measurement and Analysis of Dioxins in Waste Treatment". Quantitative analysis of the chlorinated organic compounds (dioxins) collected...

Example Embodiment

[0050] Among them, the capturing body of the same form may be configured in the same manner when, for example, the paper-like body described in the other embodiment (2) is used.

[0062] As a capture system, it will contain a specific surface area of ​​1000m 2 / g of coal pitch-based fibrous activated carbon 0.8g air-permeable paper-like body is rolled into a cylindrical shape with an inner diameter of 15mm, an outer diameter of 17mm, and a length of 120mm, with one end closed. Scheme (3) form). This capturing body was used in place of the capturing body used in the above-mentioned Example 1, and the same collecting device as in the above-mentioned Example 1 was manufactured. Using this collecting device, as in the case of Example 1, the quantitative analysis of chlorinated organic compounds (dioxins) was performed, and the same analysis results as in Example 1 were obtained. Example 3

Example Embodiment

[0025] Fig. 1 shows the schematic structure of a chlorinated organic compound collecting device used in a scheme of the collector of the present invention. Among them, this collection device 1 is a device that collects chlorinated organic compounds contained in a gas sample such as exhaust gas. In the figure, the collecting device is mainly equipped with a collecting pipe 2, a collecting device 3 (an embodiment of the collecting device according to the present invention) and a suction pipe 4.

[0063] Proper mixing specific surface area 100m 2 / g of coal tar pitch fibrous activated carbon and micro glass fiber, and then add cellulose binder as a binder component to form. Therefore, the capture body 17 of the other embodiment (5) described above, containing 3.0 g of fibrous activated carbon, with an outer diameter of 19 mm on the open end side, an outer diameter of 18 mm on the closed end side, a thickness of 5 mm, and a length of 120 mm was obtained. The obtained capturing body wa...

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...
