Asphalt oil gas treatment system

Abstract

The invention discloses an asphalt oil gas treatment system. A filter tank is arranged on the upper surface of an oil removal tank; a filter screen is arranged in the filter tank; an air outlet of thefilter tank is communicated with the filter tank through a connecting pipe; an activated carbon box is arranged on the upper surface of the bottom plate; an air outlet of the filter tank is connectedwith an air inlet of the activated carbon box through an air pipe; activated carbon is arranged in the activated carbon box; an xylene solution is arranged in the oil removal tank; one gas outlet ofa three-way joint is communicated with the oil removal tank through a gas return pipe; and an electromagnetic valve is arranged on the gas return pipe. Thereby, oil molecules in oil gas can be specially treated, the oil molecules in the oil gas can be effectively removed, the treatment effect is good, treated gas can be detected, the discharged gas is ensured to meet the emission standard, and practicability is achieved.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to an asphalt oil gas treatment system. Background technique [0002] Asphalt concrete, commonly known as asphalt concrete, is a kind of artificially selected mineral materials with a certain gradation composition, crushed stone or crushed gravel, stone chips or sand, mineral powder, etc., and a certain proportion of road asphalt materials, under strict control The mixture prepared under the conditions, the output and transportation of asphalt concrete, after the asphalt concrete is mixed by the mixer, it is discharged into the transport vehicle, and the transport vehicle transports the concrete to the designated location or the location where the road is paved. However, When the asphalt concrete is discharged from the mixer, and because the mixed asphalt concrete has a certain temperature, it is easy to emit relatively strong asphalt oil gas, which is pungent and harmfu...

[0002] Asphalt concrete, commonly known as asphalt concrete, is a kind of artificially selected mineral materials with a certain gradation composition, crushed stone or crushed gravel, stone chips or sand, mineral powder, etc., and a certain proportion of road asphalt materials, under strict control The mixture prepared under the conditions, the output and transportation of asphalt concrete, after the asphalt concrete is mixed by the mixer, it is discharged into the transport vehicle, and the transport vehicle transports the concrete to the designated location or the location where the road is paved. However, When the asphalt concrete is discharged from the mixer, and because the mixed asphalt concrete has a certain temperature, it is easy to emit relatively strong asphalt oil gas, which is pungent and harmful to the human body;

[0003] The existing application number is CN201920137694.1, which discloses an asphalt oil and gas treatment system. The asphalt oil and gas enter the pipeline from the air intake device, and then pass through the water treatment device, activated carbon treatment device and plasma treatment device in turn to remove the dust and harmful substances in the asphalt oil and gas. Removed, and then discharged to the external environment through the air outlet device, so as to achieve the purpose of improving the environmental quality of the asphalt concrete production site, but this setting does not specifically treat the oil molecules in the oil and gas, and cannot effectively remove the oil molecules in the oil and gas. The effect is not good. Moreover, after the oil and gas are treated, the treated gas is not detected, and the discharged gas cannot be guaranteed to meet the emission standards, so it is not practical
