Technical field
The utility model discloses a kind of off-line and soaks the film core apparatus, divides by International Patent Classification (IPC) (IPC) to belong to film core cleaning device class manufacturing technology field, especially relates to a kind of off-line unhurried current dynamic formula and soaks the film core apparatus.
Background technology
The maximum technology barrier of film separating application industry popularization at present is the pollution of film.After film resolution element/film core uses a period of time; Owing to process exists and being in contact with one another and pollution has been taken place for the crown_interception of material of material, filter efficiency obviously descends, and separating effect also changes; Need clean it; The pollutant of removing absorption or combining makes membrane component/film core performance be able to recover, and guarantees its separating effect.The main mode of cleaning of the membrane component/film core that pollutes at present is to use cleaning agent to clean in the equipment cocycle, or takes off membrane component/film core off-line soaking and washing.
Big in equipment cocycle cleaning flowing velocity, cleaning fluid and contaminant species exchange are fast, and cleaning efficiency is higher, but some shortcomings are also arranged:
A. energy consumption is high, need start circulating pump with booster pump cleans, and the energy consumption of cleaning is near the energy consumption of production.
B. have the speed of pollutant and cleaning agent generation cleaning reaction of considerable part slower, or pollution layer is thicker, needs to prolong scavenging period and could clean fully.
C. after there are some fluid dead angles in membrane component/film core or the runner obstruction takes place, circulate cleaning and be difficult for touching.
D. take equipment, influence is produced.
Off-line chemical agent soaking and washing, and though almost there is not energy consumption, soak time is long, but also exist deficiency:
A. can pollute the chemical agent that direct cleaning reaction takes place with film and only be present in the narrow and small runner of membrane component/film core, and the flow channel space of membrane component/film core is little, open ended chemical agent is limited, the almost very difficult membrane component/film in-core portion that diffuses into from the outside.
B. the pollutant of the membrane component/film in-core property that flows is poor, and it is outside that the pollutant that washes down can not in time be discharged to the film core, pollutes easily that thing is full to be closed or side reaction takes place.
C. cleaning makes water consumption big, must complete submergence film core during immersion.
D. because cleaning fluid and pollutant reaction speed are slow excessively, cleaning fluid is not easy to prepare the concentration that reaches suitable, and is too high or too low easily.
E. the pollutant of membrane component/film in-core is rich in nutriment, and soak time is long, and breed bacteria forms new biological pollution easily.
Summary of the invention
Deficiency to prior art; The utility model provides a kind of off-line rational in infrastructure unhurried current dynamic formula to soak the film core apparatus; In conjunction with the advantage of two kinds of cleaning methods and overcome both shortcoming, the low discharge circulation immersion that adopts the low mode of forcing down flow velocity to carry out membrane component/film core cleans.
For achieving the above object, the utility model is realized through following technical scheme:
A kind of off-line unhurried current dynamic formula soaks the film core apparatus; The some film core elements that comprise fermentation vat and pond cleaning liquid inside; Each film core element stands in the fermentation vat cleaning liquid inside, and the cleaning fluid in the fermentation vat forms the peripheral passage through water pump and washes corresponding to the top of film core element one by one through a plurality of shower nozzles.
Further, the cleaning fluid in the described fermentation vat reaches recurrent state through water pump or suction pump, and mounted valve and flowmeter carry out flow-control and reach the moving circulation purpose of unhurried current on the circulation waterway pipeline.
Further, the flow of shower nozzle rinse spray cleaning fluid is the 1/1000-1/3 of film core normal wash flow in the said peripheral passage.
Further, described shower nozzle is the shower nozzle of parallel-connection structure, and each shower nozzle is the top of aligning film core element respectively.
Further, the described film core element height that is immersed in fermentation vat cleaning liquid inside face is lower than 2/3 of film membrane component core height.
The utility model relates to the method and apparatus of a kind of off-line soaking and washing polluted membrane resolution element/film core; Use the low discharge circulating pump; In conjunction with gravity; The low discharge circulation immersion that adopts the low mode of forcing down flow velocity to carry out membrane component/film core cleans, and has that power consumption is low, cleaning efficiency is high and advantage such as using water wisely.
The utlity model has following beneficial effect:
A. soaking and washing process, it is low to consume energy, and can loss-rate circulates in line and cleans little 2 one magnitude;
B. using water wisely, cleaning fluid liquid level only need the membrane component/film core of a submergence part, can significantly reduce water consumption;
C. cleaning fluid contacts exchange fully with pollutant, can satisfy the cleaning requirement of membrane component/film core, and effective consumption of film cleaning agent is increased, and reduces film cleaning agent consumption;
D. device structure is simple, manufactures simple and easy.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Embodiment: see also Fig. 1; A kind of off-line unhurried current dynamic formula soaks the film core apparatus; The some film core elements 2 that comprise fermentation vat 1 and pond cleaning liquid inside 10; Each film core element 2 stands in the fermentation vat cleaning liquid inside, and the cleaning fluid in the fermentation vat washes corresponding to the top of film core element through water pump 3 formation peripheral passages and through a plurality of shower nozzles 4 one by one.Cleaning fluid 10 in the fermentation vat reaches recurrent state through water pump or suction pump, and mounted valve 5 and flowmeter 6 carry out flow-control and reach the moving circulation purpose of unhurried current on the circulation waterway pipeline.The flow of shower nozzle rinse spray cleaning fluid is the 1/1000-1/3 of film core normal wash flow in the peripheral passage.Each shower nozzle is the shower nozzle of parallel-connection structure, and each shower nozzle is the top of aligning film core element respectively.The height that film core element 2 is immersed in fermentation vat cleaning liquid inside face is lower than 2/3 of membrane component core height.
The design feature of the utility model is following:
A. the bottom of membrane component/film core fermentation vat is provided with leakage fluid dram and is connecting water pump; Or fermentation vat uses the suction pump that self-suction function is arranged when not having leakage fluid dram.
B. water pump is connecting the top of the spout aligning film element/film core of pipeline at the back; When cleaning many membrane components/film core, adopt the shower nozzle of parallel-connection structure, shower nozzle is aligning film element/film core respectively.
