Environment-friendly asphalt production equipment

Abstract

The invention relates to the technical field of asphalt production and waste gas treatment, in particular to environment-friendly asphalt production equipment. The equipment comprises a stirring cylinder body mounted on a bottom plate. According to the invention, rotation of the stirring cylinder body is achieved through a motor fixed to the bottom plate in a gear transmission mode; in the rotating process of the cylinder body, four fixed rollers which are located below the cylinder body, fixed to the bottom plate and connected to supporting rods keep stable rotation of the cylinder body; when raw materials are conveyed into the stirring cylinder body through a feeding groove, waste gas generated in the stirring process is pumped out through a gas pump at one end of the stirring cylinder body and conveyed into a treatment cavity, then the waste gas is treated through combustion of natural gas in the treatment cavity, and high-temperature harmless gas generated in the process is guided into an asphalt oxidation cavity; and in the asphalt oxidation cavity, high-temperature oxidation of asphalt is achieved under the combined action of the high-temperature harmless gas from the treatment cavity and oxygen from an oxygen storage cavity, and finally, the treated asphalt is discharged through a dumping groove.

Description

technical field [0001] The invention relates to the technical field of asphalt production and waste treatment, in particular to an environment-friendly asphalt production equipment. Background technique [0002] Asphalt contains a certain amount of paraffin, and the more the content is, the worse its cohesiveness and heat resistance will be. The wax content in ordinary petroleum asphalt is relatively high, but the temperature difference between the softening point and the flow state is very small. When the temperature reaches the softening point, the asphalt is close to the flow state, so it is easy to flow after construction. Treatment will cause shortcomings such as weak bonding, flowing, and easy aging. Therefore, in asphalt production, certain technical treatments must be used to remove the contained wax and improve performance before it can be used. At the same time, asphalt smoke and particulate dust It can enter the human body through the respiratory tract and skin. ...

Problems solved by technology

The wax content in ordinary petroleum asphalt is relatively high, but the temperature difference between the softening point and the flow state is very small. When the temperature reaches the softening point, the asphalt is close to the flow state, so it is easy to flow after construction. Treatment will cause shortcomings such as weak bonding, flowing, and easy aging. Therefore, in asphalt production, certain technical treatments must be used to remove the contained wax and improve performance before it can be used. At the same time, asphalt smoke and particulate dust It can enter the human body through the respiratory tract and skin. If the human body takes too much, it will cause poisoning, dermatitis, blurred vision, conjunctivitis, chest tightness, headache and other symptoms.

Long-term exposure to asphalt and asphalt fume can easily induce cancer, so it is very necessary to treat the waste gas generated in the asphalt production process. Currently, most of the paraffin in asphalt is processed by solvent dewaxing, but the recovery of the added solvent is very complicated. , In addition, the industrial treatment of waste gas is not perfect, so it is necessary to design a more efficient device for treating paraffin impurities and waste gas
