Conventional asphalt station in the production of discharge asphalt smoke will cause environmental pollution, dust, smoke, noise, waste, and other hazards to human health. With the increasingly strict environmental protection laws and the continuous improvement of environmental protection requirements, more and more attention has been paid to the environmental problems involved in asphalt mixing equipment, and it has become a hurdle that the healthy and sustainable development of the asphalt industry has to face.
The pollution status is in urgent need of improvement, environmental protection technology is in urgent need of upgrading, asphalt mixing station equipment to green, environmental protection, energy saving development is imperative.
Components and hazards of asphalt smoke
Asphalt used for road will release asphalt smoke which is harmful to human body and environment at high temperature (100℃~190℃). As a special pollutant, it is mainly composed of liquid hydrocarbon particles and gaseous hydrocarbon derivatives, most of which are tar fine mist particles of 0.1~1μm.
There are nearly 200 kinds of organic pollutants in asphalt flue gas, mainly polycyclic aromatic hydrocarbons and a small amount of heterocyclic mixtures of oxygen, nitrogen and sulfur, and the main harmful components are phenols, anthracene and benzoa [a] pyrene. General petroleum asphalt containing benzo [a] pyrene 0.1~27mg/kg, cracking petroleum asphalt 4~272mg/kg.
Benzo [a] pyrene has a strong carcinogenic effect on skin and respiratory system, and is one of the main causes of skin, lung, stomach and esophageal cancer. Asphalt smoke has obvious influence on environment and human health, and there are many different ways to treat and purify it.
EBICO asphalt flue gas recovery series burner
In recent years, according to the requirements of environmental protection, asphalt mixing stations have been equipped with asphalt smoke recovery system to effectively avoid the pollution problem caused by asphalt smoke directly discharged into the atmosphere. However, the installation of this system costs a lot. How to achieve a more economical and environmental protection effect is a topic that EBICO has been exploring and researching. Along with the continuously upgrading technology research and development, the successful launch in 2020, burner recycling asphalt smoke series, the series of burner can make asphalt mixing plant without extra adding asphalt smoke recycling system, can achieve more environmental protection, more efficient, more stable, after more than two years, won a good market feedback of mouth.
EBICO is the low nitrogen and low carbon, environmental protection of outstanding enterprises, is also the world's representative of innovative combustion technology, in highway engineering industry for decades, countless partners, for the industry has accumulated rich experience, in recent years is highly focused field of flue gas recycling asphalt stand, actively cooperate with engineering machinery enterprises, For many brands of asphalt mixing station to provide more energy saving and environmental protection combustion technology support.
In the future, EBICO will continue to adhere to the research and development concept of safety, energy saving, environmental protection and intelligence, and is committed to realizing the golden division of environmental protection and economy of asphalt station. EBICO is constantly promoting the process of environmental protection of highway construction machinery enterprises, and building green mountains with practical actions!
