Background technology: prior art Chinese patent application number 022213007, the utility model title: the comprehensive fast processor of compound wine, but treatment effect is good not enough.
Summary of the invention:
The purpose of this utility model is to overcome the shortcoming of prior art, and the compound high-accuracy filter of a kind of filtration, good purification is provided.
Compound high-accuracy filter, it is characterized in that: coarse filter 1 has water inlet A, the outlet of coarse filter 1 connects the import of pump M, the outlet of pump M connects valve F1 and valve F3, the outlet of valve F3 connects the import of waste valve F5, the outlet of valve F1 connects the import of Pressure gauge P1 and polypropylene hyperfiltration membrane assembly 2, and the outlet of polypropylene hyperfiltration membrane assembly 2 connects Pressure gauge P2 and outlet valve F4, and waste valve F2, F5 are installed in the upper side wall and the lower wall of polypropylene hyperfiltration membrane assembly 2 respectively; Polypropylene hyperfiltration membrane assembly 2 forms by the multi-layer polypropylene milipore filter is overlapping, adorns superfine order grid or filter screen in the coarse filter 1.
Operation principle:
One, the polypropylene milipore filter is a latest generation milipore filter material, compares with other milipore filter materials such as polysulfones, celluloses, and it is good that it has an intensity height, acid and alkali-resistance, anti-bacterial corrosion, heat resistance; The surface is nonpolar, do not have any suction-operated; Specific area is big, the unit volume loading density is big; Micropore evenly, the micropore form is the micro-crack type, and under identical flux, than circular hole microporous barrier rejection height, during identical rejection, bigger than circular hole microporous barrier flux, advantage is waited until in stable performance.
Two, the basic principle and the characteristics thereof of 2 ultrafiltration of polypropylene hyperfiltration membrane assembly:
1. basic principle: polypropylene hyperfiltration membrane assembly 2 forms by the multi-layer polypropylene milipore filter is overlapping.The principle that polypropylene hyperfiltration membrane assembly 2 carries out separating substances is: under certain ambient pressure effect, when solution to be separated with certain flow velocity when milipore filter one side surface flows, solvent and low molecule solute will be through the opposite side of membrane micropore to film, and tunicles such as the polymer substance in the solution, colloidal particles, pyrogen and bacterium, microorganism are retained down, thereby realize separation, the purpose that concentrates and purify, purify.
2. the characteristics of polypropylene hyperfiltration membrane assembly 2:
A. ultra-filtration process does not undergo phase transition, and energy consumption is lower;
B. ultra-filtration process is operated at normal temperatures, need not heating, is particularly suitable for the separation of heat-sensitive substances such as biological products, fruit juice, drinks, medicine, thalline, protein;
C. polypropylene hyperfiltration membrane assembly 2 is suitable for the extensive separating ranges from virus, bacterium, polymer substance to particulate;
D. the ultra-filtration and separation process is simple, corollary equipment is few, easy and simple to handle, easy care, and the separative efficiency height.
Description of drawings:
Fig. 1: compound high-accuracy filtration device structure figure of the present utility model.
The specific embodiment:
See Fig. 1, compound high-accuracy filter, it is characterized in that: coarse filter 1 has water inlet A, the outlet of coarse filter 1 connects the import of pump M, the outlet of pump M connects valve F1 and valve F3, and the outlet of valve F3 connects the import of waste valve F5, and the outlet of valve F1 connects the import of Pressure gauge P1 and polypropylene hyperfiltration membrane assembly 2, the outlet of polypropylene hyperfiltration membrane assembly 2 connects Pressure gauge P2 and outlet valve F4, and waste valve F2, F5 are installed in the upper side wall and the lower wall of polypropylene hyperfiltration membrane assembly 2 respectively; Polypropylene hyperfiltration membrane assembly 2 forms by the multi-layer polypropylene milipore filter is overlapping, adorns superfine order grid or filter screen in the coarse filter 1.
One, the use of polypropylene hyperfiltration membrane assembly 2, cleaning and maintenance,
Use:
Cleaning when (1), the polypropylene hyperfiltration membrane assembly uses for the first time, sterilization:
At first the disinfection protection liquid in the polypropylene hyperfiltration membrane assembly 2 is drained, then with clean water flushing about two hours, till unprotect liquid smell.During towards Xian, the flow-rate ratio of condensed water and ultrafiltration water is chosen as 1/5 to 1/3.
(2) operate as normal:
During polypropylene hyperfiltration membrane assembly 2 operate as normal, require system pressure between 0.1～0.25Mpa, the ratio of regulating condensed water and flow of inlet water simultaneously is 1/5～1/7, makes membrane module be in dynamic ultrafiltration state.If discontinuous work before each the shutdown, all should all be opened concentrated valve, whole valves are closed in isobaric flushing ten minutes after the shutdown, prevent secondary pollution.Before the start, should adopt the same manner flushing ten minutes once more.
Clean:
1. physics cleans
A. isobaric cleaning the: when the ultrafiltration duty, all open waste valve F2, F5, carry out the cleaning on milipore filter surface;
B. backwash: ultrafiltration water is entered membrane module from hyperfiltration membrane assembly 2 ultrafiltration mouths, discharge, the pressure when recoil pressure should be slightly larger than normal running from waste valve F2, F5.Attention: recoil water must adopt aseptic ultrafiltration water, and not can be recycled.
2. Chemical cleaning
With above chemicals of CA level and ultrafiltration water preparation cleaning agent, enter membrane module and soaked 1～2 hour, press the equal pressure cleaning way then, wash cycles membrane module 1～2 hour then, is rinsed well with clear water, can cooperate in case of necessity to adopt backwash to clean.
Two. the influent quality requirement of hyperfiltration membrane assembly
1. to the requirement of influent quality:
Water temperature:＜40 ℃ of pH values: 1～14
Turbidity:＜0.5NTU particle:＜1 μ m
Three, workflow
Produce: stoste → import A → coarse filtration → pump M → valve F
