A detection device and detection method for smoke content in asphalt

Abstract

The detection device relates to a detection device and detection method for the content of flue gas in asphalt; the detection device comprises a distillation flask; the distillation flask is arranged in an oil bath heater; the distillation flask is connected with a gas outlet pipe; the distillation flask is connected with a sample bottle through the gas outlet pipe; the sample bottle is connected with an activated carbon pipe; the distillation flask is provided with a plug with a stopper; when the device is used, a heat resistant magnetic rotor is put into the distillation flask through a neck mouth. The problems that a conventional asphalt flue gas measurement device has large asphalt use amount, narrow test temperature range, poor temperature control precision, complex composition and operation and the like are solved, so the device has the advantages of small use amount of the sample, high temperature-control range, high temperature-control precision, simple composition, convenience in measurement and the like, and simultaneously obtains the contents of heavy flue gas and light flue gas.

Description

technical field [0001] The invention belongs to the technical field of smoke content detection, and in particular relates to a detection device and a detection method for smoke content in asphalt. Background technique [0002] At present, during the process of mixing, paving and using as the raw material of waterproof membrane, asphalt has to experience a high temperature of 160-250°C, and the light components contained in it and the light components released during the thermal cracking process will be Volatilizes in large quantities in the form of asphalt fume, and these components are usually complex hydrocarbons or polycyclic aromatic hydrocarbons, which pose risks to the health of workers and the surrounding environment. In order to grasp the flue gas content per unit mass in different types of asphalt from the source, and to provide support for the process principle and load design of the corresponding asphalt fume control facilities, it is necessary to carry out corres...
