Description

technical field

[0001] The invention relates to an environmental protection treatment facility, in particular to an asphalt fume dust collection and purification system with the function of automatically separating dust and oil from asphalt fume produced in the production process of modified asphalt products. Background technique

[0002] [With the advancement of science and technology and the enhancement of people's awareness of environmental protection, people have put forward higher requirements for the air quality in the living space. For the mixed flue gas produced during the production of modified asphalt waterproofing membranes, which contains waste gas, waste oil, dust, smoke, etc., which will pollute the environment, there is currently no suitable environmental protection treatment equipment with comprehensive treatment functions on the market. , the enterprises that produce modified asphalt products basically use the screen filter general-purpose equipment certifie...
