Asphalt fume dust collection and purification system

Abstract

The invention relates to an asphalt fume dust collection and purification system. The asphalt fume dust collection and purification system comprises a dust treatment tower, an oil filtration odor removal box, a main gas spray pipeline, a turbulent flow type power wave water membrane washing tank and a precipitation, oil separation and circulation water tank, wherein a washing water tank, a dust blocking plate for blocking and separating dust, a PVC (polyvinyl chloride) ball filter material box for adsorbing dirty oil and a dust precipitation tank are arranged in the dust treatment tower, a precision oil filtration barrel, an activated carbon odor removal device and a waste oil collection pool are arranged in the oil filtration odor removal box, a spiral spray head is arranged in the main gas spray pipeline, a stainless steel compound filter layer as well as the spiral spray head and an activated carbon odor removal filter layer which are correspondingly arranged in layers are arranged at the inner layer of the turbulent flow type power wave water membrane washing tank, and multiple non-woven fabric oil filtration screens are arranged in the oil separation and circulation water tank. Dust and waste oil in asphalt fume are repeatedly washed, filtered, adsorbed, separated and respectively collected by a sectional continuous treatment method, the up-to-standard emission of waste water and air can be further ensured, and the asphalt fume dust collection and purification system has the advantages of reasonable structure, reliability in working, stable performance, high efficiency and very strong practicality.

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...
