The automatic cycle of fine catalyst afterwards is core of the invention, combines Fig. 2, Fig. 3, Fig. 4 and most preferred embodiment to this hair thus
The function and advantage of bright centrifugal waterpower retention pulse separator are further elaborated.
Water inlet pipe 9-2 enters the filter cylinder 9-15 inside centrifugal waterpower retention pulse separator not across Seal end plate 9-1
Gap location between permeable end and shell 9-16, the tail portion water inlet pipe 9-2 are connected to flat burner 9-21, and flat burner 9-21's is minimum
It is fair or slightly higher with the highest point of the outer grid 9-12 outside filter cylinder 9-15 to locate, in this way, being sprayed by flat burner 9-21 certain
The fine catalyst mixed liquor of pressure and certain flow rate carries out tangent line to the fine catalyst on filter cylinder surface and washes away, to slacken
Because fine catalyst accumulation caused by pressure difference increase.Fine catalyst mixed liquor enters centrifugation in such a way that tangent line washes away
After formula waterpower retains pulse separator inside, clear water can successively pass through outer grid 9-12, the filter cloth on the surface filter cylinder 9-15
(film) 9-11, interior grid 9-10 enter cartridge interior, are discharged after spray head 9-6 is pooled to outlet pipe 9-3, and fine catalyst
