When the filter cake layer is not formed at the initial stage of the use of conventional filter materials, it mainly depends on the interception effect of the fiber itself. When facing ultra-fine and small particles, the capture ability is poor. Polytetrafluoroethylene microporous membrane is covered on the surface of filter material through adhesive or high temperature hot pressing technology. Be...

The important pollutants of thermal power plants are sulfur dioxide and dust, and sulfur dioxide is emitted by almost all power plants because sulfur is contained in coal fuel. Sulfur dioxide irritates the respiratory tract and also seems to be irritating to the cornea. Low concentrations cause respiratory discomfort, high concentrations can be fatal. On the one hand, thermal power generation cons...

The main component of commercial SCR denitrification catalysts is vanadium-tungsten-titanium oxide. Among them, TiO2 is the carrier, WO3 is the co-catalyst, V2O5 is the active component of the catalyst, usually using urea or ammonia as the reducing agent, the main denitrification chemical reaction with ammonia as the reducing agent is: 4NO + 4NH3 + O2 → 4N2 + 6H2O(1) 2NO2+4NH3+O2→3N2+6H2O(2) NO2+N...
