A kind of environment-friendly laboratory asphalt heating device and using method thereof

Abstract

The invention discloses an environment-friendly type laboratory asphalt heating device and a using method thereof. The environment-friendly type laboratory asphalt heating device comprises an asphalt heating device body, a cylinder edge, a gas extraction device and an asphalt flue gas purifying device, wherein the outer side wall of the cylinder edge and the inner wall of an opening in the top part of the asphalt heating device body are connected; the side wall of the asphalt heating device body is of a two-layer structure; a gap exists between two layers of structures; a plurality of gas sucking holes are formed in the inner side wall of the cylinder edge; a gas extraction hole is formed in the outer side wall of the asphalt heating device body; the gas sucking holes are communicated with the gas extraction hole through the gap between the two layers of structure in sequence; the asphalt flue gas purifying device is connected with the gas extraction hole through the gas extraction device. The environment-friendly type laboratory asphalt heating device and the using method of the environment-friendly type laboratory asphalt heating device, disclosed by the invention, can be used for sucking and purifying flue gas generated during an asphalt heating process.

Description

technical field [0001] The invention relates to an asphalt heating device and a using method thereof, in particular to an environment-friendly laboratory asphalt heating device and a using method thereof. Background technique [0002] Asphalt is a complex mixture of hydrocarbons of different molecular weights and non-metallic element (O, N, S) derivatives. It is solid or semi-solid at room temperature, and viscous fluid at high temperature. It has excellent cohesiveness, Ductility and waterproof, anti-acid and alkali, anti-corrosion and other properties. Asphalt can be mainly divided into coal tar pitch, petroleum pitch and natural asphalt. Non-natural asphalt is refined and processed from the waste petroleum residue left after petroleum refining. People's lives are closely related. [0003] With the accelerated development of society, road asphalt and construction asphalt account for about 65.3% and 25.2% respectively. The amount of asphalt used in road traffic in my coun...

Problems solved by technology

[0003] With the accelerated development of society, road asphalt and construction asphalt account for about 65.3% and 25.2% respectively. The amount of asphalt used in road traffic in my country has increased sharply. Due to the increase of large vehicles and overweight and overloaded vehicles, the requirements for road performance are also increasing. The more stringent, such as compression resistance, rutting resistance, high and low temperature, temperature sensitivity, etc., although my country's road construction has achieved significant development, but transportation as a whole still cannot meet the needs of social and economic development and people's lives, and the import volume of high-quality asphalt It is still very large, but due to the high price of imported asphalt, it has prompted my country to build more asphalt plants and improve the performance of asphalt for traffic pavement. Therefore, a large number of scholars have studied the performance of asphalt and modified it to make it more performance when used. Superior, can be evenly distributed in asphalt by changing the chemical composition of asphalt or adding modifiers
