Below, the working method according to filter plant of the present utility model is described.
The course of work of one-way flexible dynamic particle membrane filter system is divided into following 3 stages: preplating mem stage, filtration stage and backwash stage.This three phases consists of a complete work period.
The preplating mem stage
At the preplating mem stage, the emphasis of work is to form the stratum granulosum that one deck has certain filter capacity on filter screen, guarantees can satisfy at filtration stage the requirement of filtering accuracy.As shown in Figure 3, at first normal filter liquor valve 442A, initial stage filter liquor valve 443, backwash inlet valve 442B, backwash flowing water Valve 445 and dirty solution valve 420 to be separated are closed, open particle suspension liquid liquid flowing valve 410, suspension returning valve 441 and filter liquor return valve 444, then will prepare in advance by certain concentration, the particle suspension liquid that contains specified particle diameter, be delivered in filter plant with pump 400, enter described turbid liquid space.Owing to having fluid pressure difference between filter screen both sides, turbid liquid space and clear liquid space, therefore there is segment fluid flow just to pass filter screen, enter the clear liquid space, but due to the particle diameter of fluid contained particle greater than aperture of filter screen, particle just is trapped in its surface by filter screen like this, therefore just forms stratum granulosum-membrana granulosa.Because most of particle suspension liquid does not pass filter screen, though so the granule density of fluid have along its flow direction and successively decrease, be not very large, add the shear action of current, the thickness of stratum granulosum-membrana granulosa can compare homogeneous.The suspension that does not pass filter screen 41 is back to the particle suspension liquid make-up tank through the hole, and it is good not enough because of water quality to pass the filter liquor of filter screen, also is back to the particle suspension liquid make-up tank through via hole 44.When stratum granulosum meets the requirements of thickness, can stop the charging of particle suspension liquid.The preplating mem stage finishes.
Filtration stage
As shown in Figure 4, after the preplating mem stage is completed, just close suspension liquid flowing valve 410, suspension returning valve 441 and filter liquor return valve 444, open simultaneously feed liquid material inlet valve 420 to be separated and initial stage filter liquor flowing water Valve 443, make feed liquid to be separated enter this filter plant by the effect of pump 400.In the initial stage of that below standard filter liquor was back to through hole 43 and treated in Separation of Solid and Liquid material fluid bath 600, waited for again and filtering.The water quality of waiting until the initial stage filter liquor reaches when producing water quality standard, closes initial stage filter liquor valve 443, opens normal filter liquor valve 442A.This filter plant enters normal filtration stage.When filter cake reached certain thickness, filtration stage finished.
Due to preplating mem stage and filtration stage, fluid is to pass from outside to inside filter screen and skeleton.At this moment, skeleton shows rigidity, can not deform, and the stratum granulosum and the filter cake that therefore form can not break.
The backwash stage
As shown in Figure 5, in this stage, close feeding liquid valve 420 to be separated and normal filter liquor valve 442A, open backwash inlet valve 442B and backwash flowing water Valve 445.Under the effect of backwashing pump 800, clean normal filter liquor is oppositely passed filter screen, and flushing simultaneously is deposited on the filter cake on filter screen etc.In the situation that adopt the support frame net of the one-way flexible dynamic particle film described in Chinese utility model patent 201210298133.2, this filter liquor can promote the skeleton distortion, be with thus electric filter also to deform, cause stratum granulosum and filtrate cake bursting on filter screen.Under the flushing of reverse flow, the stratum granulosum and the filter cake that are attached on filter screen can be washed from the filter screen upper punch easily.These rinse the particle that gets off and the suspension that is trapped under the acting in conjunction of gravity and current, enter in the macropore 145 of filter assemblies below, then are pushed out filter plant.Stage subject to backwash finishes, and closes backwash inlet valve and backwash flowing water Valve.Equipment is in enter the state of next work period.
Although top reference preferred embodiment of the present utility model is described the utility model in detail, the utility model never is confined to this, but under the prerequisite that does not deviate from marrow of the present utility model, can make various modifications and substitute.For example, described gland and moving head can only play the effect of the whole filter plant of sealing and not comprise net-filter assembly.In addition, the quantity that is formed on the hole on framework needn't be four, but can increase as required or reduce.In addition, the formation position in hole is not restriction also, as long as can be connected with turbid liquid space and clear liquid space.
