Embodiment Construction

[0017] The process steps of the present invention are: 1) placing the adsorption device in a vacuum freeze dryer for drying treatment; after the vacuum freeze drying treatment is completed, the adsorption device is weighed to obtain the mass before adsorption, and after the weighing is completed, the adsorption device is placed in In the freezer, pure polypropylene cotton is installed in the adsorption device;

[0018] 2) Heat the asphalt per unit mass, and keep the temperature of the asphalt at 160°C~185°C through the heating constant temperature device;

[0019] 3) Introduce the smoke and dust volatilized by heating the asphalt into the adsorption device for adsorption treatment;

[0020] 4) After the adsorption treatment is completed, the adsorption device is subjected to freeze-drying treatment, and after the freeze-drying treatment, the adsorption device is weighed to obtain the mass after adsorption;

[0021] 5) According to the difference between the mass before adsorp...

Abstract

The invention discloses a device for sampling asphalt smoke dust, which consists of a closed container, a heating furnace, a temperature controller, a freezer, an absorption device, a water container and a dry air supplying device, wherein an air outlet of the dry air supplying device is connected with an air inlet of the closed container; an air outlet of the closed container is connected with an air inlet of the absorption device; an air outlet of the absorption device is positioned under the liquid level of the water container; the heating furnace is connected with the temperature controller; a temperature sensing part of the temperature controller is connected with the closed container; the heating furnace is used for heating the closed container; asphalt with unit mass is arranged inthe closed container; the absorption device is arranged in the freezer; adsorption substance is arranged in the absorption device; and the freezer is internally provided with cooling substance. The invention also discloses a method for measuring the content of the asphalt smoke dust. The invention has the beneficial technical effects that the sampling device is simple in structure and convenient to operate, the measurement method is simplified and rapid, and the measurement result is high in accuracy.

Description

technical field [0001] The invention relates to a method for measuring smoke and dust and a sampling device thereof, in particular to a method for measuring the content of asphalt smoke and dust and a sampling device for smoke and dust of asphalt. Background technique [0002] During the construction of asphalt, the heating temperature is as high as 160°C~180°C, and the light components in it will volatilize in large quantities. These light components are not only very complex in composition, but also toxic and harmful. These volatilized light components seriously endanger human health and cause environmental pollution. Since these light components overflow in the form of asphalt fumes, in order to reduce the impact of asphalt on the human body and the environment, it is necessary to control the asphalt fumes generated during the construction and production of asphalt. The content of asphalt smoke and dust generated during asphalt construction and production is measured e...
