Embodiment
The present invention is further illustrated with reference to embodiment, but the present invention is not limited to following examples.
Involved by the present invention can self-cleaning nutrients in sea water pre-filtering preparation system, nutritive salt detection pretreatment unit it is many
The acetate fiber filter membrane or glass fiber filter used for laboratory, it is impossible to for monitoring on-line.And the on-line filtration of commercialization
Apparatus structure is simple, and only single-stage is filtered, and without backwashing function, is not useful in the confession long-term nutrition in high turbidity seawater
Salt detection is used.
As shown in figure 1, the system includes：Pump 1:Pumping raw water is to water sample preparation system；Pump 2:Pumping clear water, is used to
Clean water sample preparation system；Magnetic valve:Control water route break-make and balance pressure；Multi-stage filter core:Filter raw water；Safety valve:Protect
Hold system pressure；Raw water box:Deposit raw water to be filtered；Filtered water tank:Clear water used when depositing purging system；Waste water tank:Storage is clear
Wash the waste water of system and the clear water remained in system.
It is preferred that, as shown in figure 1, multi-stage filter core uses three-level filter core, wherein afterbody filter core is filtered for 0.45um apertures
The online pre-filtrating equipment of nutrients in sea water of the core present invention, including carry out one-level filter core, two grades of filter cores and the three-level of filtration treatment
Filter core, described one-level filter core is 200 μm of aperture polyurethane screens, and two grades of described filter cores are 60 μm of aperture resin filter element layers,
Described three-level filter core is the wood fibre filter core layer in 0.45~1 μm of aperture.Described one-level filter core is arranged on high density PVC
In the inlet segment port of body, sandwiched high density PVC supporting clapboards, described three between two grades of described filter cores and three-level filter core
Level filter core is all encapsulated in the water side of high density PVC cylinders.Filter core involved by the present invention, can select two grades of filter cores, level Four filter
The filter core of core or more level, its principle is identical, is only that the simple of quantity increases or decreases, but three-level filter core by aperture by slightly extremely
The three-stage filtration carefully set, can realize basic demand.
As shown in figure 1, the operation principle and the course of work and water sample preparation process of the system, what it is with three-level filter core is
Exemplified by system, start pump 1, open magnetic valve F1, F2, remaining magnetic valve is turned off, now raw water will be pumped into water sample preparation by pump 1
System, raw water is exported from F2 after being filtered through multi-stage filter core and discharged, and institute's draining sample is the water quality for meeting inspection criterion（Water sample is passed through
0.45um membrane filtrations）.
In water sample preparation process, when the delivery port pressure of pump 1 is more than system safe pressure, safety valve can be opened, by more than
Pressure reaches the effect of protection water sample preparation system with drainage pattern pressure release.Cleaning process terminates laggard in water sample preparation process
OK, process and step are：Pump 1, magnetic valve F1, F2 are closed, pump 2 is opened and extracts clear water, and open magnetic valve F5, F8, punching respectively
Wash third level filter core；Until third level filter core washing time is completed, magnetic valve F5, F8 are closed, F4, F7 is opened and rinses second level filter
Core；Until second level filter core washing time is completed, magnetic valve F4, F7 are closed, F3, F6 is opened and rinses first order filter core；Until the
Two grades of filter core washing times are completed, and close magnetic valve F3, F6 and water pump 2.
In cleaning process, when the delivery port pressure of pump 2 is more than system safe pressure, safety valve can be opened, by unnecessary pressure
Power reaches the effect of protection water sample preparation system with drainage pattern pressure release, and safety valve discharge clear water is flow back into clear water reserviors, saves
About clear water.
Evacuation procedure is：Magnetic valve F6, F7, F8 are opened, by the pressure venting in filter core；
Until work of drilling is completed after latter fix time, continue to open magnetic valve F9, F10, F11, with the pressure in balanced filter core,
Empty the residual clear water in filter core；Until the certain time after the completion of upper step（Clear water excludes clean）, close all magnetic valves.Row
After the completion of sky, Installed System Memory stays a small amount of moisture, when starting water sample preparation next time, only needs the short time to moisten and system system can be used after pipe
Standby water sample.
