The single-machine bag dust collector is a small bag dust collector imported from the American Fuller Company and has the technical level of the 1980s. When the dusty gas contains acid or alkaline and the gas temperature is ≤190°C, Ryton (polyphenylene sulfide) needle punched felt is often used. When the gas temperature is ≤240°C and the acid and alkali resistance requirements are not too high, P84 (polyimide) needle felt should be used. When the dust-containing gas is flammable and explosive gas, choose anti-static polyester needle felt. When the dust-containing gas contains a certain amount of moisture and is flammable and explosive gas, choose waterproof, oil-proof and anti-static (three-proof) Polyester needle punched felt. This small bag dust collector is economical and practical, has a simple and compact structure, is easy to install, and is easy to maintain (inner filter type). It is mainly used for dust collection at emission and dust points such as the top, bottom of the warehouse, warehouses, warehouse tops and various conveyors. , this machine uses polyester cloth bags, and the dust removal effect reaches 99.8% when the inlet temperature is <120℃. If there are special uses, we can provide a stand-alone bag dust collector with temperature-resistant and corrosion-resistant filter materials.
