1. Site survey: inspect the actual situation of the user’s site, integrate the user’s preliminary idea, collect the user’s engineering needs, and recommend the best configuration of the equipment.
2. Plan planning: plan the most reasonable site layout based on the user’s on-site situation and comprehensive user needs.
3. Optimal selection: The expert team optimizes the best plan, customizes personalized products, and fully meets the needs of users with the best cost performance.
4. Comprehensive environmental protection: comprehensive dust pollution, asphalt fume pollution, nitrogen oxide pollution, various noise pollution, adopt advanced comprehensive environmental protection measures to ensure that Qingshui Green Mountain is not affected by asphalt stations.
During the construction of asphalt mixture mixing, pollutants such as CO2, SO2, and bitumen flue gas are generated. At the same time, it is accompanied by noise and dust pollution, which seriously affects the ecological environment. The sources are mainly as follows:
1. Fume and dust pollution generated during the feeding process and mixing the main building and the aggregate site;
2. Harmful gases such as asphalt smoke, nitrogen oxides, etc. generated in the drying cylinder burner, finished product discharge port, asphalt tank, sulfide, heavy oil tank, and chimney;
3. Asphalt storage, oil unloading, heating and heating, burner operation, and odor pollution caused by the asphalt mixture on the transport truck; loading of the loader, operation of the induced draft fan, rotation of the drying drum, lifting of the aggregate elevator, and screening by the vibrating screen Noise pollution caused by time.
In the face of increasingly serious pollution problems, after years of continuous attempts and improvements, Yalong Equipment has obtained mature dust and asphalt flue gas treatment technology with independent intellectual property rights. The equipment has made breakthrough progress in preventing dust and asphalt fume pollution and has truly become a dust-free, smoke-free, and odorless green environmental protection product. Yalong equipment guarantees that the environmental protection indicators are as follows:
(1)Organized emission standards: particulate matter emissions <20mg/m3, asphalt smoke <10mg/m3, benzopyrene <0.30×10mg/m3, non-methane total hydrocarbons <10mg/m3; better than GB16297-1996 “Air Pollutants” “Comprehensive Emission Standard” Grade II standard.
(2)Unorganized emission standards: particulate matter emissions <20mg/m3, asphalt smoke <10mg/m3, benzopyrene <0.3×10-4mg/m3, total non-methane hydrocarbons <10mg/m3; there is no unorganized emission of asphalt smoke .
(3) Noise: ambient noise 7:00～21:00≤65dB(A), 5:00～7:00, 21:00～23:00≤60dB(A), 23:00～5:00≤55dB (A), control station noise ≤ 70dB (A), noise emission meets the requirements of the national standard GB12348-2008 “Environmental Noise Emission Standard for Industrial Enterprises”.
