Problems solved by technology

For daily laboratory tests with low testing frequency, or general research for working condition comparison and optimization of operating parameters, investing in such a laboratory will cause a lot of waste
[0007] In summary, the currently widely used detection methods have the problems of cumbersome steps, low efficiency, and high cost, and the absorption range is narrow, so the scope of application is not wide

Embodiment 1

[0086] In this embodiment, the method for collecting and detecting characteristic organic matter in the process of gaseous pollutants produced in the sludge drying process of urban sewage treatment plant, the steps are as follows (the material is raw sludge as an example), and the device is as follows: figure 1 Shown:

[0087] (1) Weigh 60 grams of sludge sample, put it in a quartz crucible, put it into the tube furnace, push the quartz crucible with the sample to the constant temperature section in the center of the corundum furnace tube with a furnace hook, and then install it. Lan; Connect the gas guide pipes of the tube furnace in and out to ensure the airtightness of the tube furnace;

[0088] According to the data conditions numbered 1 in Table 1, turn on the carrier gas, adjust the tube furnace test system, heat the material, and then keep it warm; the organic gaseous pollutants released by the material when heated escape with the carrier gas, collected by the pipeline ...

Abstract

The invention belongs to the technical field of resources and environments and relates to a method for separating and collecting gas-state organic pollutants and an implementation device thereof. The method comprises the following steps: (1) heating materials in a heating device, and preserving the temperature, wherein in the heating process, carrier gas is introduced, the gas-state organic pollutants released by the heated materials escape along with the carrier gas, are collected through a pipeline and are output to a condenser pipe for condensation, the condensed gas-state organic pollutant flue gas is divided into two paths which are respectively introduced into a first absorption system and a second absorption system, and characteristic gas-state organic pollutants are separated from the flue gas; and (2) enriching and separating the collected absorption liquid of the gas-state pollutant, and detecting the liquid in a detection system. The method can serve as an operating method for researching a release rule of the gas-state organic pollutants in the process of heating multiple materials such as sludge, tobaccos and industrial production solid wastes.

Description

technical field [0001] The invention belongs to the technical field of resources and environment, and relates to a method for separating and collecting gaseous organic pollutants and a device for realizing the same. Background technique [0002] Industrial waste gas, especially the waste gas released when heating solid waste such as sludge and municipal solid waste, is an important source of air pollutants. After being heated, solid waste can decompose into phenol, benzene series, polychlorinated biphenyls, polycyclic aromatic hydrocarbons, alcohols, aldehydes, acids, and esters, which will have adverse effects on the natural environment, human health, and facilities and equipment. For example, phenol, benzene series, polychlorinated biphenyls, polycyclic aromatic hydrocarbons and most alcohols, aldehydes, acids, and esters will cause harm to the environment and human health. Alcohols, aldehydes, acids, and esters can affect mechanical equipment. Normal use. In academic re...
