大型木工機加車間需要根據行(xing)業特(te)點(dian)來選擇除塵設備，進而提升生產車(che)間內部環(huan)境空氣質量(liang)。今天國(guo)昌環(huan)保就來(lai)談(tan)談(tan)木工機(ji)加(jia)車(che)間粉塵治(zhi)理(li)方案。

布袋除塵器以其除塵效率高、性能穩定、性價比高等特點，受到家具制造企業的青睞，因此選擇布袋除塵器來治理木工機加車間粉塵是較為合適的。布袋除塵(chen)器主(zhu)要由除(chu)塵(chen)器主(zhu)體、除(chu)塵(chen)風機、配套除(chu)塵(chen)管(guan)道及(ji)其附屬配件(jian)組成，利用布(bu)袋的(de)(de)過濾特性(xing)，濾除(chu)掉木(mu)工機加(jia)車間包括鋸、鉆、刨、銑(xian)、砂等多工序，復(fu)雜工況下產生的(de)(de)塵(chen)屑顆粒物，實現凈(jing)化車間內部(bu)環境空氣(qi)的(de)(de)目的(de)(de)。
