As Fig. 1, shown in Figure 2, a kind of vertical filter, it comprises filter, pre-coating device circulates, cleaning device and power set, power set are filter, circulate pre-coating device and cleaning device provides power, filter comprises the filter vat 1 of vertical placement, the inlet valve to be filtered 14 that is connected with filter vat 1 reaches the air bleeding valve 20 that is connected with the circulation bucket 19 of the pre-coating device of circulation with product outlet valve A11, the pre-coating device that circulates comprises circulation bucket 19, with circulation bucket 19 loop head valve 18 that is connected and loop exit valves 21, cleaning device comprises the rinse water inlet valve 15 that can be connected with loop head valve 18 by pipeline, flushing valve 7 that is connected with filter vat 1 and residual cake valve 6.Filter vat 1 comprises the staving of hollow, and the staving upper and lower side is provided with the liquid outlet is connected with pipeline, and the staving inwall axially is provided with rinse bar 4, and the staving centre is provided with central shaft 3, and arrangement longitudinally is provided with filter 2 on the central shaft 3.Filter 2 adopts KPZ to close screen pack.Power set are provided with feed pump 17, clean motor 5, feed pump 17 with rinse water inlet valve 15, treat that filtrate inlet valve 14 is connected with pump chamber air bleeding valve 16, cleaning motor 5 is connected with filter.Filter vat 1 is connected by the surplus liquid outlet valve 13 of control valve 8 with series connection.Treat that filtrate inlet valve 14, product outlet valve A11 open, loop head valve 18 cuts out, pump chamber air bleeding valve 16, formation filtration circuit when air bleeding valve 20 is opened.Rinse water inlet valve 15, flushing valve 7, residual cake valve 6 are opened, surplus liquid inlet valve 22, formation scavenger circuit when control valve 8 is closed.By circulation bucket 19, rinse water inlet valve 15, treat that filtrate inlet valve 14 cuts out, loop head valve 18, feed pump 17, control valve 8, when opening, loop exit valve 21 constitutes circulation precoating loop.Be provided with the circulation that can observe filtrate clarity in the circulation precoating loop and look tube 23, this circulation is looked tube 23 and is communicated with loop exit valve 21.The operate as normal that is communicated with filter vat 1 is set looks tube 9 and sample valve 10.The staving of filter vat 1 is provided with peep hole 24.

One, the precoating of liquid circulation and filter aid

With rinse water inlet valve 15, treat that 14 connecting leg roads of filtrate inlet valve connect with pipeline with clean water and receiver respectively, close rinse water inlet valve 15, filtrate inlet valve 14 is treated in unlatching, to treat that filtrate pumps in filter vat 1 and the circulation bucket 19, circulate when being full of liquid in the filter vat 1 and to get final product when liquid level arrives 3/4 in the bucket 19, open loop head valve 18, loop exit valve 21, product outlet valve B12 this moment, close simultaneously and treat filtrate inlet valve 14, make system self circulation, close, begin to rehearse air valve 20 for several times to drain air in the filter vat 1, prepare precoating.

The precoating super-cell: precoating diatomite dosage and model proportioning are generally determined voluntarily according to actual conditions such as the muddy degree of stoste, concentration, impurity granularity and quantity.Starting cleaning motor 5 allows filter 2 rotations (can not open flushing valve 7 this moment) that filter aid is adsorbed on the filter upper surface equably, form filter course, approximately precoating 15-20 minute, can look the clarity that tube 23 is observed filtrate from circulation, perhaps also can observe filtrate clarity from sample valve 10 samplings.

Two, the filter process of filtrate

After treating that the filter aid precoating finishes, can change the normal filtration state over to, open and treat filtrate inlet valve 14, product outlet valve B12 or product outlet valve A11, whether close loop head valve 18 simultaneously, and open air bleeding valve 20,16 exhausts of pump chamber air bleeding valve, it is normal to observe Pressure gauge, filter beginning, after treating that filtrate filtration finishes, close and treat filtrate inlet valve 14, product outlet valve B12 or product outlet valve A11, finish filter process.

Three, the cleaning process of filter

Along with the prolongation of time, when filter vat 1 pressure surpasses 0.3MP, and rate of discharge hour or filter liquor when not reaching the clarity that regulation requires reply filter vat 1 inner filtration sheet 2 clean.Before the cleaning, start feed pump 17, open surplus liquid inlet valve 22, surplus liquid outlet valve 13 simultaneously, with surplus liquid in the filter vat 1 (by surplus liquid inlet valve 22 go into, surplus liquid outlet valve 13 goes out) drain to specified hold-up vessel.During cleaning, open rinse water inlet valve 15, flushing valve 7, residual cake valve 6, and open and close pump chamber air bleeding valve 16 drains the pump chamber air, close other all valves, rinse water in filter vat 1 by the water jet ejection of rinse bar 4, start feed pump 17 once more and clean motor 5, allow filter 2 turn to spin rinse in accordance with regulations with central shaft 3.Rinse back (observing the flushing situation by peep hole 24) for to be filtered 2 well, the operation related valve cleans once pipeline.Residual cake valve 6 must be kept normally open so that rinse water is in time discharged in the filter vat 1 during flushing.Above-mentioned cleaning process need not pulled down filter vat 1 and filter 2, allows filter 2 flushing while rotating.
