Operating process of the present invention:
(1), filter press operating process
Said like lower component: fermented liquid storage tank 1, valve F1, pump B1, plate-and-frame filter press 2, valve F2, valve F6, valve F5 constitute the filter press system; Wherein, valve F2 is a plate press filtration purified liquor outlet valve, and F6 is the turbid solution reverse flow valve, and F5 is the fermented liquid variable valve.
Fermented liquid through valve F1, pump B1, gets into plate-and-frame filter press under the driving of pump B1, clear liquor gets into plate press filtration clear liquid storage tank 4 through F2, accomplishes the filter press process.Wherein:
1, function as follows with the parallelly connected fermented liquid variable valve valve F5 of pump B1 outlet: 1, adjustment plate-and-frame filter press 2 work initial stage pump B1 pump into the flow size of fermented liquid, and the filtering layer that quickens plate-and-frame filter press 2 forms; Later stage, the machine internal pressure rose rapidly along with the filtering layer of plate-and-frame filter press 2 is more and more thicker, and filtration velocity slows down; Open F5, release the fermented liquid that part pump B1 pumps into, let plate-and-frame filter press 2 diaphragm cavity internal pressures slowly rise; Up to the full solid filter residue of diaphragm cavity content; Turn off F5 and B1 pump again, start pneumatics, press dry filter residue.
2, function as follows with the parallelly connected turbid solution reverse flow valve F6 of plate-and-frame filter press 2 outlets: at the 2 work initial stages of plate-and-frame filter press, filtering layer does not form or is not formed into enough thick as yet, and a large amount of solid phases see through barrier film and get into filtrating; At this moment, open F6, let filtrating be back to storage tank; After plate-and-frame filter press 2 formation enough thick filtering layer, filtrating are enough limpid, close F6, open valve F2; Plate-and-frame filter press 2 works on, and filtrating flows to clear liquid storage tank 4 through valve F2, accomplishes up to this batch filter press.
(2), tubular membrane micro-filtration operating process
Said like lower component: the pump B4 of press filtration clear liquid storage tank 4, valve F3, pump B2 and outlet parallel connection, valve F9, F7, F8, and outlet connect valve F4 etc. and constitute the tubular membrane microfiltration systems; Wherein, pump B4, valve F9, micro-filtrate membrane filtration machine 5, outlet connect the formation tubular membrane filter recycle systems such as valve F4.
Open F3, ejector priming B2, the filter press clear liquid in the press filtration clear liquid storage tank 4 pumps into the tubular membrane filter recycle system under pump B2 drives; Open F9, start recycle pump B4, open F4; The filter press clear liquid gets into micro-filtrate membrane filtration machine 5 and obtains other clear liquid of micro-filtration level under the driving of B4, and clear liquid gets into storage tank 6 through F4; Raffinate continues continuous circulating filtration under the effect of B4, and simultaneously, B2 constantly replenishes feed liquid in the micro-filtration recycle system; Along with sludge concentration progressively improves, micro-filtration recycle system internal pressure can progressively raise, when reaching certain pressure in the micro-filtration recycle system; Open valve F7, with raffinate release in the storage tank 4 with jar in the clear liquid mixed diluting, close F7 again and continue aforesaid operations; After multi-pass operations, micro-filtration filtering system internal pressure is fluctuation no longer, when being stabilized in set(ting)value; Explain that sludge concentration is consistent with the interior concentration of micro-filtration filtering system in the press filtration clear liquid storage tank 4, this moment, micro-filtration filtered near the limit; Then, open F13, in jar 4, replenish a certain amount of pure water, residue in the thinning tank is closed F13, repeats above-mentioned micro-filtration operation, up to The above results occurring; Close F7 then, open F8, residue is pressed into storage tank 1, residue is carried out filter press, accomplish the operation of tubular membrane micro-filtration this moment.
(3), rolled film ultrafiltration and concentration operating process
Said like lower component: liquid concentrator storage tank 6 after the micro-filtration ultrafiltration, F10, B3, ultrafiltration membrance filter machine 8, F14, F16, F12, F11, and respiratory organ 7 constitute rolled film ultrafiltration and concentration systems.
Micro-filtration clear liquid after the micro-filtration ultrafiltration in the liquid concentrator storage tank 6 is under the driving of pump B3, through valve F10, pump B3, entering ultra-filtration membrane thickner 8; Waste liquid such as small molecules and water passes rolled film and discharges through waste liquid outlet valve F12, and liquid concentrator is liquid concentrator storage tank 6 after F14, the ultrafiltration of F16 backflow micro-filtration, and aforesaid operations moves in circles; Reach necessary requirement up to the liquid concentrator enzyme activity; Turn off F16 then, open finished product outlet valve F11, liquid concentrator is discharged to finished product storage tank through product outlet.
Respiratory organ F7 plays the 6 jars of internal pressure effects of liquid concentrator storage tank after the micro-filtration ultrafiltration of regulating.
