A kind of asphalt multi-tube foaming system and process

Abstract

An asphalt multi-pipe foaming system includes a pitch supply module, a ground water supply module, a high-pressure water supply module, a multi-pipe foam module, a diesel cleaning module, an air supply module, a drainage module and an electrical control module. When foaming, the high-pressure water supply module provides high-pressure water for the multi-tube foaming module, the asphalt supply module provides asphalt with a certain pressure and temperature for the foaming module, and the electrical control module collects the asphalt weight signal of the asphalt supply module, which has a certain pressure and temperature. The asphalt and high-pressure water are foamed in the foaming chamber, and the diesel cleaning module and the air supply module can clean the chamber after production. The present invention can automatically select the number of foam tubes according to different asphalt mixing plant models and match different asphalt addition ratios to meet the requirements of different formulas; it has a sampling function to meet the experimental requirements required by customers for changing production formulas; the large cycle pressure building pipeline can be Effectively solve the problem of slow pressure build-up during foaming or insufficient water pressure input into the foaming chamber, which affects the asphalt foaming effect.

Description

technical field [0001] The invention relates to the technical field of asphalt production, and more specifically relates to an asphalt multi-tube foaming system and process. Background technique [0002] In recent years, the highway business has developed rapidly, and the mileage of asphalt pavement construction and maintenance has also increased year by year. As the asphalt mixing plant produces a large amount of waste gas including asphalt flue gas in the process of producing asphalt products, which causes air pollution and huge energy consumption, it is urgent for us to find some solutions that can alleviate or solve these problems. Warm mix asphalt technology has been gradually welcomed by the market due to its many advantages such as reducing harmful gas emissions, reducing energy consumption, extending construction seasons, and reducing paving temperature. [0003] In the existing asphalt foaming warm mix technology, there are mainly the following shortcomings: 1. It ...
