Manual High Filter Area Carbon Steel Candle Filter Housing With For
Chemical/ Oil / Filtration
Candle filter is a fully closed filter system, the main components
are material tank, gas storage tank, filter pump, candle filter,
pipeline, valve, PLC electrical control and so on.
During filtration, a pump is used to send the material to be
filtered into the filter. When the liquid passes through the filter
cloth, the solid substances in the liquid will gradually accumulate
on the surface of the filter cloth. When these solid substances
reach a certain thickness, a filter cake is formed. Because the gap
between the filter cake particles is very small, the escape of
particulate impurities in the liquid is blocked, so that the
filtrate becomes clear. Before the filter cake layer is formed, the
discharged "clear liquid" returns to the raw material tank for
circulation. Filter until the filter cake layer is formed (which
can meet the filtration requirements), the filter provides a signal
to the PLC to control the clear liquid not to circulate, and the
clear liquid is sent to the next process through the filter valve
for normal filtration.
After normal filtration for a period of time, when the filter cake
layer on the porous candle core reaches a certain thickness, the
rate of filtrate passing through the filter cake decreases, the
filtration efficiency becomes poor, and the filter pressure rises
(above 0.5MPc). At this time, the differential pressure switch (or
pressure The sensor) provides a signal to the PLC to stop the
filter pump, close the feed valve, open the positive blow valve,
and then drain the residual liquid in the filter. When the liquid
in the filter is lower than the filter element, open the drain
valve and the residual liquid passes through the drain valve. At
this time, the pressure in the filter drops rapidly. The PLC
receives the low pressure signal, closes the forward blowing valve,
and opens the back blowing valve (compressed air, nitrogen or
saturated steam) for back blowing, so that the filter cake falls
off, and after a certain period of back blowing ( 30 seconds), stop
backflushing, open the slag discharge port of the filter for slag
discharge, close the slag discharge port after the slag discharge
is completed, complete a filtration cycle, return to the initial
state before filtration, and prepare for the next round of
filtration.
