Description
Technical field
The utility model relates to a kind of gathering-device, particularly dioxin gathering-device in the consumer waste incineration flue gas.
Background technology
Dioxin is the general designation of many chloros dibenzo to dioxin (PCDDs) and many chloros dibenzofurans (PCDFs), is mainly derived from the secondary pollution that produces in the processing procedure of domestic waste, medical waste and electronic waste.The reason that is formed with two aspects of dioxin-like chemical in the common combustion process: be the dioxin-like chemical of sneaking in the rubbish on the one hand, be the dioxin-like chemical that produces in the waste incineration process on the other hand, and dioxin mainly is present in flue dust and the flue gas in the burning process.In harm, dioxin not only can cause immune system infringement and dysgenesia, also is considered to have very strong carcinogenicity, even trace is also very harmful to the mankind.Therefore containing the compound of dioxin and/or furans composition in collection and the analysis stationary source waste gas, is extremely important to improving air quality and air conservation.
European standard prEN 1948 has stipulated the sampling and the analytical method of three kinds of dioxin: filtration/condensation method, dilution method, cold process are handled.The dioxin that prevents that China still finds no independent intellectual property right at present generates and the dioxin sampling apparatus.In some developed countries, as the U.S., all there have been the dioxin sample devices of comparative maturity in Germany, Japan, Italy etc., the technology of using is similar, but all compare localization, sampling seems heavy to flowability, can not adapt to the national conditions of China well, and, limited carrying out of Chinese dioxin monitoring owing to blockade on new techniques, cost an arm and a leg and all factors such as later period maintenance seeervice cycle of equipment is long.Therefore, the dioxin-like chemical gathering-device that research and development has free intellectual property has important and practical meanings and supporting role for the content of burning process dioxin such as accurate analysis house refuse and the research of carrying out the dioxin synthesis mechanism.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art, a kind of dioxin that can fully absorb in the flue gas is provided, improve dioxin in the fume bioaccumulation efficiency, reduce the dioxin sampling error and can improve dioxin gathering-device in the consumer waste incineration flue gas of dioxin monitoring accuracy.
In order to achieve the above object, the technical solution adopted in the utility model is:
Dioxin gathering-device in the consumer waste incineration flue gas, it comprises the double pipe heat exchanger that tank and two-stage at least link to each other successively, the import of first order double pipe heat exchanger is connected with sample lines, the outlet of the prime double pipe heat exchanger in the adjacent two-stage double pipe heat exchanger is connected by connecting line with the import of back level double pipe heat exchanger, the bottom of every grade of double pipe heat exchanger has the condensation interface, on the connecting line of the import of outlet that connects first order double pipe heat exchanger and second level double pipe heat exchanger, first thermometer and filter cylinder are installed successively, the n-hexane Drexel bottle is housed in described tank successively, first surge flask, the resin filling bottle, the toluene Drexel bottle and second surge flask, be connected by conduit between the bottle chamber of the adjacent bottle in the described tank, the outlet of the afterbody double pipe heat exchanger in the double pipe heat exchanger that described two-stage at least links to each other successively is connected with the bottle chamber of described n-hexane Drexel bottle by the inlet ductwork that second thermometer is housed on it, the bottle chamber of described second surge flask with its on vavuum pump and flowmeter be housed export pipeline be connected, the connecting line that described filter cylinder is installed is provided with thermostat.
Advantage of the present utility model is: owing to toluene solution air-washer and toluene solution cleaning heat exchange sleeve inwall have been added in the rear portion of handling in resin adsorption, improved the bioaccumulation efficiency of dioxin, made in the consumer waste incineration tail gas dioxin monitoring more accurate.In addition, adopt this gathering-device, reduced the cost of sample devices, meet the requirement of the sampling of flowing, make the dioxin monitoring more convenient reliable.
Description of drawings
Accompanying drawing is the structural representation of dioxin gathering-device in the consumer waste incineration flue gas of the present utility model.
The specific embodiment
Below in conjunction with specific embodiment the utility model is described in detail.
Dioxin gathering-device in the consumer waste incineration flue gas of the present utility model as shown in drawings, it comprises the double pipe heat exchanger 1 that tank 7 and two-stage at least link to each other successively, the import 13 of first order double pipe heat exchanger is connected with sample lines, the outlet of the prime double pipe heat exchanger in the adjacent two-stage double pipe heat exchanger is connected by connecting line with the import of back level double pipe heat exchanger, the bottom of every grade of double pipe heat exchanger has condensation interface 10, on the connecting line of the import of outlet that connects first order double pipe heat exchanger and second level double pipe heat exchanger, first thermometer 2 and filter cylinder 3 are installed successively, n-hexane Drexel bottle 5 is housed in described tank successively, first surge flask, resin filling bottle 6, be connected by conduit between the bottle chamber of adjacent bottle in the toluene Drexel bottle 11 and second surge flask and the described tank.The outlet of the afterbody double pipe heat exchanger in the double pipe heat exchanger that described two-stage at least links to each other successively is connected with the bottle chamber of described n-hexane Drexel bottle 5 by the inlet ductwork that second thermometer 4 is housed on it, bottle chamber of described second surge flask with its on vavuum pump 8 and flowmeter 9 be housed export pipeline be connected.The connecting line that described filter cylinder is installed is provided with thermostat.11 is cooling water inlet in the accompanying drawing, and 12 is coolant outlet.
For improving filter efficiency, preferably adopt particle detention efficient 〉=99.95% of filter cylinder to dioxin in the flue gas.Described filter cylinder can be the glass fibre filter cylinder.
The method of operating of this gathering-device is as follows:
(1) guarantees that by regulating cooling water flow and filter cylinder frame thermostat the flue-gas temperature of glass fibre filter cylinder import department maintains about 110 ℃.
(2) in double pipe heat exchanger bottom, the second level conical flask is set, receives the condensate water that contains dioxin-like chemical that condensation produces in the flue gas.In tank, put into mixture of ice and water 14, n-hexane Drexel bottle 5, first surge flask, the resin filling bottle 6 that XAD-2 resin is housed in it, the toluene Drexel bottle 11 that toluene is housed in it and second surge flask that the clean water of n-hexane is housed in it are positioned in the mixture of ice and water, the double pipe heat exchanger that will link to each other successively through two-stage at least and the flue gas of filter cylinder continue to be cooled near 0 ℃, make that the XAD-2 resin in the resin filling bottle is the highest to the adsorption efficiency of dioxin.
