Description
Technical field
The utility model relates to the treating apparatus that gravure note printing is wiped the version waste liquid, especially relates to the hollow fiber ultrafiltration equipment back purge system that gravure note printing is wiped the version waste liquid.
Background technology
Gravure note printing is wiped the version waste liquid owing to contain a large amount of pigment, filler, and composition such as organic connection material, the processing mode of gravure wiping waste liquid mostly adopts hollow fiber ultrafiltration equipment in the seal paper money industry at present, the hollow fiber ultrafiltration utilization be physics screening principle, after operation a period of time, because factor films such as concentration polarization can be polluted, influence separative efficiency, seeing through liquid measure will descend, and will clean this moment to film, and just should clean film this moment, in order to recover separating power, recover percolate flux.
Ultrafiltration apparatus commonly used at present can only unidirectionally clean when cleaning, and promptly seeing through liquid can only a direction flow through in fenestra, and cleaning has certain limit
The processing mode of gravure wiping waste liquid lacks hollow fiber ultrafiltration equipment back purge system in the existing seal paper money industry.And hollow fiber ultrafiltration equipment can only clean in the front of membranous wall when cleaning, and scavenging period is longer usually, and cleaning efficiency is low, DeGrain.
Summary of the invention
The purpose of this utility model is to provide a kind of gravure note printing to wipe the hollow fiber ultrafiltration equipment back purge system of version waste liquid.
The purpose of this utility model is achieved in that
Gravure note printing is wiped the hollow fiber ultrafiltration equipment back purge system of version waste liquid, comprise waste liquid and cleaning fluid mixing inlet, one-level liquid waste processing shutoff valve, booster pump, secondary liquid waste processing shutoff valve, see through liquid shutoff valve, milipore filter waste liquid inlet shutoff valve, concentrating spent liquor outlet, see through liquid outlet, hyperfiltration membrane assembly, waste liquid inlet, see through liquid outlet shutoff valve, anti-booster pump, anti-shutoff valve, the waste liquid exhaust-valve of cleaning of cleaning; Wherein: the mixing inlet of waste liquid and cleaning fluid is successively by one-level liquid waste processing shutoff valve, booster pump, secondary liquid waste processing shutoff valve, being connected through the liquid outlet conduit through the liquid shutoff valve and on being arranged on hyperfiltration membrane assembly; Hyperfiltration membrane assembly enters the mouth with secondary liquid waste processing shutoff valve, is communicated with through the pipeline between the liquid shutoff valve by waste liquid; The mixing of waste liquid and cleaning fluid inlet also successively by anti-cleaning shutoff valve, the anti-booster pump that cleans with secondary liquid waste processing shutoff valve, be communicated with through the pipeline between the liquid shutoff valve; Pipeline between booster pump, the secondary liquid waste processing shutoff valve also is communicated with the waste liquid exhaust-valve; The pipeline that sees through the liquid shutoff valve, sees through between the liquid outlet also with through liquid outlet shutoff valve is communicated with; Hyperfiltration membrane assembly is in communication with the outside by the concentrating spent liquor outlet.
Advantage of the present utility model: install additional and can realize the front-back two-sided cleaning of membranous wall after gravure note printing is wiped the hollow fiber ultrafiltration equipment back purge system of version waste liquid, improved the flexibility of cleaning and reduced scavenging period.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Reference numeral: the mixing of waste liquid and cleaning fluid inlet 1, one-level liquid waste processing shutoff valve 2, booster pump 3, secondary liquid waste processing shutoff valve 4, see through liquid shutoff valve 5, milipore filter waste liquid inlet shutoff valve 6, concentrating spent liquor outlet 7, see through liquid outlet 8, hyperfiltration membrane assembly 9, waste liquid inlet 10, see through liquid outlet shutoff valve 11, anti-booster pump 12, anti-shutoff valve 13, the waste liquid exhaust-valve 14 of cleaning of cleaning.
The specific embodiment
Below in conjunction with embodiment and contrast accompanying drawing and be described in further detail to this reality is novel.
Gravure note printing is wiped the hollow fiber ultrafiltration equipment back purge system of version waste liquid, comprise waste liquid and cleaning fluid mixing inlet 1, one-level liquid waste processing shutoff valve 2, booster pump 3, secondary liquid waste processing shutoff valve 4, see through liquid shutoff valve 5, milipore filter waste liquid inlet shutoff valve 6, concentrating spent liquor outlet 7, see through liquid outlet 8, hyperfiltration membrane assembly 9, waste liquid inlet 10, see through liquid outlet shutoff valve 11, anti-booster pump 12, anti-shutoff valve 13, the waste liquid exhaust-valve 14 of cleaning of cleaning; Wherein: the mixing of waste liquid and cleaning fluid inlet 1 is exporting 8 pipelines through liquid and be connected by one-level liquid waste processing shutoff valve 2, booster pump 3, secondary liquid waste processing shutoff valve 4, on seeing through liquid shutoff valve 5 and being arranged on hyperfiltration membrane assembly 9 successively; Hyperfiltration membrane assembly 9 by waste liquid inlet 10 with secondary liquid waste processing shutoff valve 4, be communicated with through the pipeline between the liquid shutoff valve 5; The mixing of waste liquid and cleaning fluid inlet 1 also successively by anti-cleaning shutoff valve 13, the anti-booster pump 12 that cleans with secondary liquid waste processing shutoff valve 4, be communicated with through the pipeline between the liquid shutoff valve 5; Pipeline between booster pump 3, the secondary liquid waste processing shutoff valve 4 also is communicated with waste liquid exhaust-valve 14; The pipeline that sees through liquid shutoff valve 5, sees through between the liquid outlet 8 also with through liquid outlet shutoff valve 11 is communicated with; Hyperfiltration membrane assembly 9 is in communication with the outside by concentrating spent liquor outlet 7.
Operation principle:
Liquid waste processing and positive cleaning: during the waste liquid normal process, waste liquid enters hyperfiltration membrane assembly 9 from the mixing inlet 1 of waste liquid and cleaning fluid through one-level liquid waste processing shutoff valve 2, booster pump 3, secondary liquid waste processing shutoff valve 4, milipore filter waste liquid inlet shutoff valve 6, see through liquid then through seeing through liquid outlet 8, flowing to equipment for reclaiming through liquid outlet shutoff valve 11
Concentrate through concentrating spent liquor export 7 discharge currents after circulatory pool and new liquid mix again the mixing inlet 1 from waste liquid and cleaning fluid enter the composition circulating disposal process.
Just cleaning commonly used then is to have changed waste liquid into cleaning fluid, and circulation also changes service sink into, route with dispose waste liquid consistent.
The anti-cleaning of cleaning: cleaning fluid is through instead cleaning shutoff valve 13, instead clean booster pump 12, see through liquid shutoff valve 5, seeing through liquid outlet 8 and enter hyperfiltration membrane assembly 9 outsides, liquid after the cleaning is discharged through concentrating spent liquor outlet 7, carries out pressure by secondary liquid waste processing shutoff valve 4, waste liquid exhaust-valve 14 simultaneously and regulates.
