Abstract:
A method of removing dust from dust laden gases said method comprising the steps of:passing a flow of gases laden with dust particles at a selected first gas stream velocity through a first dust removing mechanism capable of creating multiple vortexes of gases;agglomerating the dust particles of the flow of gases as the flow of gases passes through the first dust removing mechanism, said first gas stream velocity being selected to cause agglomeration of said dust particles;passing the gas stream carrying agglomerated particles at a selected second gas stream velocity through a second dust removing mechanism capable of creating multiple vortexes of gases;further aglomerating the dust particles as the gas stream flows through the second dust removing mechanism;removing the agglomerated dust particles as the gas stream passes through the second dust removing mechanism at said second gas stream velocity;wherein the second gas stream velocity is substantially slower than the first gas stream velocity, the second gas stream velocity being selected to cause further agglomeration of said dust particles and to preclude carrying of agglomerated particles from the second dust removing mechanism.
