Problems solved by technology

[0003] In the asphalt production industry, the production capacity of the device can basically reach 400T / h, and it is gradually increasing. Some devices can even reach 1000T / h. If the asphalt softening point is manually detected and then the operating parameters of the equipment are adjusted, the precision time of the production equipment can be effectively adjusted. It will be delayed for more than one hour, resulting in a great waste of cost and materials

Embodiment 1

[0041] Install a mass flow meter on the asphalt product output pipeline of an asphalt production enterprise, and set up a corresponding sampling port. The purpose of this sampling port is to prepare for taking standard samples in the early stage and establish a basic database. After the database is established, it is necessary to re-sample and establish the database when replacing different kinds of crude oil. If the same crude oil is used, it is not necessary to repeatedly establish the benchmark data.

[0042] 1. Install the mass flow meter: add a thermal mass flow meter A on the output pipeline of the asphalt product, and install the mass flow meter on the outgoing pipeline of the device, and transmit the displayed specific gravity and temperature online to the communication data terminal for extraction.

[0043] 2. Install the asphalt sampling port: set the sampling port B, and the position is set within 5 meters behind the flow meter A.

[0044] 3. Standard data collectio...

Abstract

The invention belongs to the field of asphalt, and in particular relates to a method for monitoring the softening point of asphalt. The method comprises the following steps: a) in the asphalt production process, monitoring the specific gravity of asphalt and the asphalt temperature in the output pipeline of the asphalt product; b) according to the monitored The asphalt specific gravity and asphalt temperature data and the pre-fitted asphalt softening point calculation formula are calculated to obtain the asphalt softening point; the asphalt softening point calculation formula is obtained according to the following steps: extracting multiple samples from the output pipeline of the asphalt product, The specific gravity, temperature and softening point of the asphalt were analyzed by linear regression, and the calculation formula of asphalt softening point was obtained by fitting. The monitoring method provided by the invention can realize the on-line monitoring of the softening point of the asphalt finished product in the asphalt production process, without frequent manual sampling and traditional softening point detection operations.

Description

technical field [0001] The invention belongs to the field of asphalt, in particular to a method for monitoring the softening point of asphalt. Background technique [0002] In the asphalt production industry, the softening point index is an important value for evaluating the high temperature performance of asphalt. Through the softening point determination method in the "JTG E20--2011" transportation industry standard, special equipment and instruments are used. The samples were prepared and tested by the global method according to the steps required by the specification, and the indicators were obtained after simple calculation. The overall time to complete the whole process including sampling, sample preparation, equipment preparation, and personnel testing is at least 1.5 hours, and there are also errors in equipment, climate, and personnel operations. [0003] In the asphalt production industry, the capacity of the device can basically reach 400T / h, and it is gradually ...
