環(huán)境保護(hù)是我國(guó)的一項(xiàng)國(guó)策,除塵裝置的作用是減少粉塵排放濃度,保護(hù)大氣環(huán)境。瀝青混凝土攪拌設(shè)備在生產(chǎn)過(guò)程中由于骨料的含塵和燃燒過(guò)程中的各種廢氣被強(qiáng)制吸出,將影響較大范圍的空氣質(zhì)量,農(nóng)林作物的生長(zhǎng)和居民的生活環(huán)境,本身工地的工作環(huán)境首當(dāng)其沖,甚至影響燃燒質(zhì)量。因此,這些被吸出的煙塵氣體必須經(jīng)過(guò)凈化處理達(dá)到國(guó)家規(guī)定的環(huán)保要求,經(jīng)袋式除塵后排塵量≤50mg/Nm3,為國(guó)家一級(jí)標(biāo)準(zhǔn)。

本機(jī)采用的布袋式除塵裝置是一個(gè)高效除塵裝置。布袋式除塵器采用有機(jī)纖維或無(wú)機(jī)纖維組織物做成過(guò)濾袋。將煙塵濾出,可捕捉0.074mm以上的灰塵,除塵效率可達(dá)99%。
Environmental protection is a national policy in our country. The function of dust removal devices is to reduce the concentration of dust emissions and protect the atmospheric environment. During the production process of asphalt concrete mixing equipment, the dust contained in the aggregates and various exhaust gases from the combustion process are forcibly extracted, which will affect the air quality in a large area, the growth of agricultural and forestry crops, and the living environment of residents. The working environment of the construction site itself is the first to be affected, and even the combustion quality may be affected. Therefore, these extracted smoke and dust gases must be purified to meet the national environmental protection requirements. After bag-type dust removal, the dust emission should be ≤ 50mg/Nm3, which is the national first-class standard.
1. Structure
The bag-type dust collector adopted by this machine is a highly efficient dust removal device. The bag-type dust collector uses organic or inorganic fiber fabric to make filter bags. It filters out smoke and dust and can capture dust particles larger than 0.074mm, with a dust removal efficiency of up to 99%.
