Asphalt multi-pipe foaming system and process

Abstract

The invention discloses an asphalt multi-pipe foaming system. The system comprises an asphalt supply module, a ground water supply module, a high-pressure water supply module, a multi-pipe foaming module, a diesel oil cleaning module, a gas supply module, a drainage module and an electrical control module. During foaming, the high-pressure water supply module provides high-pressure water for the multi-pipe foaming module, the asphalt supply module provides asphalt with certain pressure and temperature for the foaming module, the electrical control module collects an asphalt weight signal of the asphalt supply module, the asphalt with certain pressure and temperature and the high-pressure water are foamed in a foaming cavity, and the diesel oil cleaning module and the gas supply module can clean the cavity after production is finished. Different asphalt adding proportions can be matched with asphalt mixing plants according to models of different asphalt mixing plants, the number of foaming pipes is automatically selected, and different formula requirements are met; the system has a sampling function, and meets the experiment requirement for changing the production formula of a customer; and a large circulation pressure buildup pipeline can effectively solve the problem that the asphalt foaming effect is affected due to slow pressure buildup or insufficient water pressure input into the foaming cavity during foaming.

Description

technical field [0001] The invention relates to the technical field of asphalt production, and more specifically refers to an asphalt multi-tube foaming system and process. Background technique [0002] In recent years, the highway industry has developed rapidly, and the construction and maintenance mileage of asphalt pavement has also increased year by year. Because the asphalt mixing plant produces a large amount of waste gas including asphalt fume during the production of asphalt finished materials, which causes air pollution and huge energy consumption, etc., prompting us to find some solutions that can alleviate or solve these problems. Warm mix asphalt technology has gradually been welcomed by the market due to its many advantages such as reducing harmful gas emissions, reducing energy consumption, extending the construction season, and reducing paving temperature. [0003] In the existing asphalt foaming warm mixing technology, there are mainly the following deficien...
