Be described in detail below by way of the operation logic of process to interior external pressure precoating formula dynamic membrane support body provided by the invention and dynamic membrane system such as internal pressure, external pressure, backwashes:
External pressure process:
Poured into by coalescents in water tank 5, open water pump, water enters cylindrical shell 4 together with coalescents, then whole cylindrical shell 4 is full of, water enters into supporter inside by the gap on dynamic membrane support body 1, and the pipeline formed from inside flow into end socket 3, then by pipeline reflow tank 5.Coalescents in water is when water flows through dynamic membrane support body 1, and a part is through gap, and major part is dammed by gap, or self forms bridge formation.Thereafter coalescents is built bridge stop, and constantly increases the thickness of bridge formation.Bridge formation is compacted, and water can through the hole of the gap between coalescents and coalescents particle self, to dynamic membrane support body 1 intermediate flow.Suspension in water is stopped by the bridge formation that coalescents is formed, and can not enter the middle part of dynamic membrane support body 1, and the water entered in the middle part of dynamic membrane support body 1 is processed water, i.e. water purification.Connected region in the middle part of the first space 31 in such end socket 3, card hole 21, dynamic membrane support body 1 can be referred to as clean water area; The region that second space 41 and dynamic membrane support body 1 outside of cylindrical shell 4 inside are formed is referred to as former pool.The bridge formation that coalescents is formed and the former pool of dynamic membrane support body separate with clean water area.
Inside press through journey:
Coalescents is poured in water tank 5, open water pump, water enters the first space 31 in end socket 3 together with coalescents, then whole first space 31 is full of, and the inside of thermally coupled flow film support 1, water enters into supporter outside by the gap on dynamic membrane support body 1, is full of the second space 41 in whole cylindrical shell 4, then by pipeline reflow tank 5.Coalescents in water is when water flows through dynamic membrane support body 1, and a part is through gap, and major part is dammed by gap, or self forms bridge formation.Thereafter coalescents is built bridge stop, and constantly increases the thickness of bridge formation.Bridge formation is compacted, and water can through the hole of the gap between coalescents and coalescents particle self, to dynamic membrane support body 1 flows outside.Suspension in water is stopped by the bridge formation that coalescents is formed, and can not enter the outside of dynamic membrane support body 1, and the water entering dynamic membrane support body 1 outside is processed water, i.e. water purification.Connected region in the middle part of first space of such end socket 3 inside, card hole 21, dynamic membrane support body 1 is referred to as former pool; The region that the second space of cylindrical shell 4 inside and dynamic membrane support body 1 outside are formed is referred to as clean water area.The bridge formation that coalescents is formed and the former pool of dynamic membrane support body separate with clean water area.
Visible, the crack that the angle that the chamfering of upper and lower two panels annular wafer is formed is formed to upper and lower two panels annular wafer superposition is all descending (no matter inner pressed or external-compression type), because this angle exists, the coalescents of precoating is easy to form " bridge formation effect ", formative dynamics film.Suspension in former water is stopped by the outer auxiliary agent of Dynamic Membrane, and water is drill-through by the space between the hole of Dynamic Membrane coalescents particle itself and coalescents.Intermembranous pressure reduction strengthens, and by the bridge formation compacting that Dynamic Membrane auxiliary agent is formed, not easily loosens, ensure that effluent quality.The supporter of other material such as stainless steel cloth, non-woven fabrics, is easily out of shape after being under pressure, and makes the bridge formation local failure of auxiliary agent, causes auxiliary agent to leak, and the water quality of water is produced in impact.Thin slice adopts hard material, and be not easy distortion after film forming is under pressure, the bridge formation of auxiliary agent is survivable, and auxiliary agent can not leak, and the water quality of producing water keeps stable.
Backwash process:
Current superpose from upper and lower two panels annular wafer 10 crack formed and impact toward angle, the bridge formation that coalescents is formed is broken up, crack is very thin, the outside impact that flushing water is just very concentrated, the surge of every bar crack is large and even, the filter cake that filter aid can be formed is washed open from supporter and breaks up, and effectively can reduce the water yield and the time of backwash.In contrast, the supporter of other materials such as stainless steel cloth of the prior art, non-woven fabrics, Yuan Shui side is substantially identical with the area producing water side, backwash hydraulic pressure skewness, comparatively large close to water inlet, cake layer is easily rushed to open and breaks up, and backwashing water major part is from flowing away here, pressure away from place side's flushing water of water inlet is just very little, and cake layer is not easily washed out.Some position is easily washed out, and backwashing water pours off from these positions in a large number, and some position is not easy to be flushed to, and coalescents is just adsorbed on online always.
In sum, the present invention changes dynamic membrane support body supporting surface into hard material, enhances support effect, and bridge formation is not easily loosened, and effluent quality improves, and meanwhile, the present invention also enhances backwash effect; Can be used as External Pressure Type supporter, also can be used as interior die mould supporter, principle communicates, and can change as required; In addition, annular flake provided by the invention is formed by stacking, and easily processes, and cost reduces, quality assurance.
