Abstract

The invention discloses a smoke oil-gas-dust separation recycling system of an asphalt mixing station, which comprises a working box body, a mixing bin is mounted on one side of the outer top surface of the working box body, an electrical tar precipitator is mounted on one side of the top surface of the mixing bin, and a getter pump is connected between a smoke outlet at the top end of the mixing bin and the input end of the electrical tar precipitator; an oil collecting tank is connected to an oil outlet of the electrical tar precipitator through a pipeline, an oil pump is installed on the lower side of the oil collecting tank, an asphalt tank is fixed to the side, close to the mixing bin, of the inner bottom face of the working box body, a combustor is installed at the bottom end of the asphalt tank, a gas gathering pipe II is arranged on one side of the spiral guide pipe, and an induced draft fan II is arranged at one end of the gas gathering pipe II. The device is reasonable in design, a large amount of smoke, oil, gas and dust generated by stirring hot asphalt and various aggregates in the mixing bin of the asphalt mixing station can be effectively separated, and separated substances can be recycled.

Description

technical field [0001] The invention belongs to the field of tail gas treatment of an asphalt mixing plant, in particular the invention discloses a smoke oil gas dust separation recovery and reuse system of an asphalt mixing plant. Background technique [0002] The mixing bin of the asphalt mixing plant will produce a lot of smoke oil, gas and dust due to mixing hot asphalt and aggregate during operation. The mixing bin of the existing mixing plant is usually not closed, and the smoke oil gas produced by it will Dust will be discharged into the air. Because asphalt contains high boiling point mineral oil and a small amount of carbon and sulfur compounds, at high temperature, it may be oxidized and decomposed to produce toxic gases such as carbon monoxide, hydrogen sulfide and sulfur dioxide, causing pollution and harm to the environment. people in good health. [0003] At present, the method of separating dust in asphalt mixing plants will directly pass the dusty gas to the...
