Abstract
The utility model discloses a filtering system for solid-liquid separation. The filtering system comprises a primary filtering device and a secondary filtering device, wherein the primary filtering device and the secondary filtering device are sequentially distributed along a pipeline; the secondary filtering device is distributed in the downstream part of the primary filtering device in the flowing direction of fluid to be filtered in the pipeline; a bag filter is used as the primary filtering device; and a membrane filter is used as the secondary filtering device. As the filtering system for solid-liquid separation, comprising the bag filter and the membrane filter, can completely filter activated carbon in chemical liquid, the activated carbon which serve as impurities can be prevented from entering subsequent chemical reaction. The filtering system is simple and convenient to combine, small in size and suitable for batched installation on pipelines through which the chemical liquid flows; and due to the small size of the filtering system, convenience can be brought for operators to easily clean contents filtered out from the bag filter and the membrane filter, so that the working strength of the operators is reduced.

The specific embodiment
Below in conjunction with accompanying drawing the technical scheme in the utility model preferred embodiment is clearly and completely described, obviously, described preferred embodiment only is a preferred embodiment of the present utility model, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
Fig. 2 is the structural representation of the filtration system of the utility model embodiment 1.
Filtration system comprises bag filter 101 and membrane filter 102, and both are arranged on the pipeline 103 successively.The chemical liquid that carries active carbon mobile bag filter 101 and membrane filter 102 of also successively flowing through in pipeline 103 from last device (not shown).If limit with the aforementioned flow direction of chemical liquid in pipeline 103 of carrying active carbon, bag filter 101 is arranged on the upstream of membrane filter 102.
The chemical liquid that carries active carbon from last device (not shown) at first flows into bag filter 101, and bag filter 101 is about 99% with the major part in the chemical liquid, and the active carbon filtering also is contained in the filter bag of its outfit.Chemical liquid through once filtering flows out bag filter 101 and flows into membrane filter 102 via pipeline 103, carries out secondary filter in membrane filter 102.Flow out membrane filter 102 and be transported to next device through the chemical liquid of secondary filter and carry out chemical reaction/processing via pipeline 103.
The built-in filter bag hole of bag filter 101 is excessive, is more suitable for filtering large granular impurity.Only rely on the bag filter 101 can't be with the complete filtering of the active carbon in the chemical liquid.In the downstream of bag filter 101 membrane filter 102 is set, because membrane filter 102 allows the particle that passes through littler, activated carbon granule can't pass through, thus fully filtering the active carbon in the chemical liquid.Through not containing active carbon in the chemical liquid after the secondary filter processing, reach the purpose of removing fully, thoroughly prevent because of leaking carbon influence operation use down.
The inlet place of membrane filter 102 is equipped with back flush valves 104, and the liquid outlet place is equipped with back flush valves 105.Utilize back flush valves 104,105, easily active carbon is gone out, greatly reduce labor intensity of operating personnel by the mode of medium recoil.
In the present embodiment, bag filter 102 is selected small-sized bag filter for use, opens flange (not shown) soon by what be equipped with on it, can clear up active carbon easily.
Fig. 3 is the structural representation of the filtration system of the utility model embodiment 2.
Filtration system comprises bag filter group 201 and membrane filter 202, and both are arranged on the pipeline 203 successively.The chemical liquid that carries active carbon mobile bag filter group 201 and membrane filter 202 of also successively flowing through in pipeline 203 from last device (not shown).If limit with the aforementioned flow direction of chemical liquid in pipeline 203 of carrying active carbon, bag filter group 201 is arranged on the upstream of membrane filter 202.
The chemical liquid that carries active carbon from last device (not shown) at first flows into bag filter group 201, be diverted in first bag filter 211, second bag filter 212 and the 3rd bag filter 213, above-mentioned first bag filter 211, second bag filter 212 and the 3rd bag filter 213 are with the major part in the chemical liquid, be about 99%, the active carbon filtering also is contained in the filter bag of its outfit.Chemical liquid through once filtering flows out bag filter group 201 and flows into membrane filter 202 via pipeline 203, carries out secondary filter in membrane filter 202.Flow out membrane filter 202 and be transported to next device through the chemical liquid of secondary filter and carry out chemical reaction/processing via pipeline 203.
When the active carbon that needs filtering more for a long time, can also improve disposal ability by bag filter in parallel more.
The inlet place of membrane filter 202 is equipped with back flush valves 204, and the liquid outlet place is equipped with back flush valves 205.Utilize back flush valves 204,205, easily active carbon is gone out, greatly reduce labor intensity of operating personnel by the mode of medium recoil.
