When specifically used, pending water-containing sludge is in stoste slot, and under ultrasonic wave effect, temperature gets a promotion,
In biological cell by broken wall.Later, mixture is flowed out from outlet tube, under the effect of gravity, is flowed into sludge sump, necessary
When, water pump is added in outlet tube, to promote the flowing of feed liquid.
Before Dynamic membrane-separation is carried out, the precoating of advanced Mobile state film layer is completed jointly by dynamic film layer and the first filtering layer
Separation of solid and liquid.Under the swabbing action of vacuum pump, required dynamic thicknesses of layers is gradually sucted in rotary drum outer surface, is reinjected
Mixed liquor under vacuum suction effect, proceeds by separation of solid and liquid.Filtered solution is inhaled into filtering internal filtering in rotating drum liquid collection conduit quilt
It takes away, sludge is attracted to dynamic film surface, is scraped off by the scraper of doctor unit, and doctor unit auto-feed constantly scrapes off
Contaminated dynamic film layer, after dynamic film layer is scraped clean, away from drum surface certain distance（About 15mm）When, scraper is automatic
Feed-disabling, then withdrawing, re-starts the precoating of dynamic film layer, into next working cycles.
Filtered solution is inhaled into rotary drum internal channel and is pumped points four kinds, corresponding four kinds different rotary drums designs：First clock：Center
Liquid inner tube is cased with out in pipe, outer layer is provided with hole, forms negative pressure for taking out air, internal layer connection immersible pump aspirates filtrate；Second
Filtered solution is collected in the inner cavity of rotary drum under the suction of vacuum pump, then enters percolate collection tubes road inner tube through immersible pump and taken out
Go out.The third：Filtered solution, into each filtrate pipe, is extracted under the suction of vacuum pump subsequently into percolate collection tubes road.4th
Kind：Filtered solution is collected in the inner cavity of rotary drum, is then flow to from liquid pass hole near filtrate branch pipe under the suction of vacuum pump,
Then enter percolate collection tubes road through immersible pump to be extracted.
When Dynamic membrane-separation system operation is to after a certain period of time, the first filtering layer is blocked, and separative efficiency declines, and thus needs
Backwash is carried out, to restore separative efficiency, vacuum pump, the first valve is closed at this time, opens the second valve, water pump, filtrate is from filter
Flow container is extracted, and into rotary drum, filter cloth is backwashed.
Dewatered sludge after the separation of Dynamic membrane-separation system, enters hollow blade dryer from feed inlet and is handled.
Under the action of high temperature hot gas, sludge is further dried, and is discharged after dry from the discharge port of drying machine.Subsequently into carbonization machine,
Under the action of heating head, at high temperature, sludge is carbonized, and becomes available resource.The high-temperature flue gas that carbonization machine generates, from going out
Gas port is discharged into drying machine, as the supplement of high temperature hot gas, so as to fulfill the recycling of energy.
