Embodiment
The utility model is further illustrated with reference to embodiment, but the utility model is not limited to following examples.
Involved by the utility model can self-cleaning nutrients in sea water pre-filtering preparation system, nutritive salt detection pretreatment dress
Acetate fiber filter membrane or glass fiber filter that mostly laboratory uses are put, is not used to monitor on-line.And commercialization is online
Filter apparatus configuration is simple, and only single-stage filters, and without backwashing function, the confession not being useful in high turbidity seawater is long-term
Nutritive salt detection uses.
As shown in figure 1, the system includes：Pump 1:Pumping raw water is to water sample preparation system；Pump 2:Pumping clear water, 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.
Preferably, 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 core nutrients in sea water of the present utility model, including carry out the one-level filter core of filtration treatment, two level filter core and
Three-level filter core, described one-level filter core are 200 μm of aperture polyurethane screens, and described two level filter core is 60 μm of aperture resin filter elements
Layer, described three-level filter core are the wood fibre filter core layer in 0.45~1 μm of aperture.Described one-level filter core is arranged on high density
In the inlet segment port of PVC cylinders, sandwiched high density PVC supporting clapboards, institute between described two level filter core and three-level filter core
The three-level filter core stated all is encapsulated in the water side of high density PVC cylinders.Filter core involved by the utility model, two level filter can be selected
The filter core of core, level Four filter core or more level, its principle is identical, is only that the simple of quantity increases or decreases, but three-level filter core passes through
Aperture by that slightly to 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, and now raw water will be pumped into water sample preparation by pump 1
System, raw water are exported from F2 after multi-stage filter core filters and discharged, and institute's draining sample is the water quality for meeting inspection criterion（Water sample passes 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 has the function that to protect 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 opens magnetic valve F5, F8 respectively, punching
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 level filter core washing time is completed, and closes 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 has the function that to protect 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 after work of drilling completes latter fix time, continue to open magnetic valve F9, F10, F11, with balanced filter core
Pressure, empty the residual clear water in filter core；Until the certain time after the completion of upper step（Clear water excludes clean）, close all electromagnetism
Valve.After the completion of emptying, Installed System Memory stays a small amount of moisture, when starting water sample preparation next time, can be used after only needing short time profit pipe
System prepares water sample.
It should be appreciated that although the present specification is described in terms of embodiments, not each embodiment only includes one
Individual independent technical scheme, this narrating mode of specification is only that those skilled in the art will should say for clarity
For bright book as an entirety, the technical scheme in each embodiment may also be suitably combined to form those skilled in the art can
With the other embodiment of understanding.
The a series of tool described in detail only for feasibility embodiment of the present utility model of those listed above
Body illustrates that they are simultaneously not used to limit the scope of protection of the utility model, all to be made without departing from the utility model skill spirit
