Abstract
The utility model discloses a kind of regenerating unit of heavily contaminated hollow membrane, it is characterized in that: comprise a cleaning case, described cleaning case is provided with alkaline cleaner adding set, acidic cleaner adding set, means for feeding acid, adder-subtractor and strong oxidizer adding set, also comprise be connected successively by pipeline and cleaning case scavenging pump, at least one for installing the putamina of hollow-fibre membrane to be cleaned, the product water out of described putamina is connected cleaning case with dense water out by reflux line.The regenerating unit of heavily contaminated hollow membrane described in the utility model, the beneficial effect had is: have the object that cleaning performance is good, cleaning efficiency is high and can realize the regeneration of heavily contaminated hollow-fibre membrane.
Description
Technical field
The utility model relates to UF membrane field, particularly a kind of regenerating unit of heavily contaminated hollow membrane.
Background technology
At present, the high permeating flux of hollow-fibre membrane (abbreviation hollow membrane) and rejection, the performances such as resistance to pressure, resistance to cleaning, temperature tolerance make this assembly industrially be widely used.But the hollow membrane on-line cleaning of heavily contaminated type is difficult to recover membrane flux and rejection, makes fouling membrane aggravate further, film new capability meets cannot meet explained hereafter requirement, must change film core.Face the problems such as life cycle is short after changing film core equally, cause business processes cost increase.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide one can realize the regeneration of heavily contaminated hollow-fibre membrane, extends hollow membrane service life, reduces the regenerating unit of the heavily contaminated hollow membrane of business processes cost.
For achieving the above object, the technical scheme that the utility model proposes is: a kind of regenerating unit of heavily contaminated hollow membrane, it is characterized in that: comprise a cleaning case, described cleaning case is provided with alkaline cleaner adding set, acidic cleaner adding set, means for feeding acid, adder-subtractor and strong oxidizer adding set, also comprise be connected successively by pipeline and cleaning case scavenging pump, at least one for installing the putamina of hollow-fibre membrane to be cleaned, the product water out of described putamina is connected cleaning case with dense water out by reflux line.
Preferably, when described be greater than 1 for the putamina installing hollow-fibre membrane to be cleaned time, respectively for hollow-fibre membrane to be cleaned is installed putamina between parallel with one another.
Preferably, the described inlet channel for the putamina installing hollow-fibre membrane to be cleaned is provided with pulse of compressed air cleaning device.
Preferably, described scavenging pump is provided with frequency-converting control device.
Adopt technique scheme, the regenerating unit of heavily contaminated hollow membrane described in the utility model, the beneficial effect had is:
1) cleaning case is provided with various medicament adding device, can automatically add various medicament according to membrane component pollution condition, and system temperature too high after can automatically stop cleaning, soak;
2) scavenging pump adopts VFC, and circular flow changes in real time, and medicament needs to adopt low discharge low flow velocity to run during fully reaction; When needing fast flush to go out pollutant, the backwashing manner of high flow capacity high flow rate can be adopted;
3) system configuration pulse of compressed air cleaning device, can effective friction film surface, automatically can to carry out mixing wastewater with air and wash and the mode such as gas friction cleaning, makes to clean more thoroughly, rapider;
4) mixing wastewater with air is washed and is made cleaning more thorough;
5) have that cleaning performance is good, cleaning rapidly, the object of heavily contaminated hollow-fibre membrane regeneration can be realized.
Accompanying drawing explanation
Fig. 1 is the regenerating unit device schematic diagram of heavily contaminated hollow membrane described in the utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1, the regenerating unit of heavily contaminated hollow membrane described in the utility model, comprise a cleaning case 10, described cleaning case 10 is provided with alkaline cleaner adding set, acidic cleaner adding set, means for feeding acid, adder-subtractor and strong oxidizer adding set, also comprise be connected successively by pipeline and cleaning case 10 scavenging pump 20, at least one is for installing the putamina 30 of hollow-fibre membrane to be cleaned, hollow-fibre membrane to be cleaned is installed in putamina 30, and the product water out of described putamina 30 is connected cleaning case 10 with dense water out by reflux line 40.
Preferably, when described be greater than 1 for the putamina 30 installing hollow-fibre membrane to be cleaned time, respectively for hollow-fibre membrane to be cleaned is installed putamina 30 between parallel with one another.
Preferably, the described inlet channel for the putamina installing hollow-fibre membrane to be cleaned is provided with pulse of compressed air cleaning device 50.
Preferably, described scavenging pump 20 is provided with frequency-converting control device.
During concrete use, a certain amount of pure water (adjusting according to film core quantity) is added in cleaning case, open scavenging pump, cleaning uses high-frequency to run flushing membrane core, if water outlet is muddy, survey and change flushing water till water outlet is not muddy, then add cleaning agent online according to hollow membrane pollution condition, carry out low frequency influent stream amount wash cycles, when pH detector detects pH decline, medicament should be added immediately and keep pH value, till pH is unchanged; Now, pulse of compressed air cleaning device, enters compressed air and carries out mixing wastewater with air pulse and wash; Increase scavenging pump frequency and carry out high flow flush, if pH changes should add medicament, if water outlet muddiness should change cleaning fluid, until hollow-fibre membrane recovers flux, cleaning completes.
Although specifically show in conjunction with preferred embodiment and describe the utility model; but those skilled in the art should be understood that; not departing from the spirit and scope of the present utility model that appended claims limits; in the form and details the utility model is made a variety of changes, be protection domain of the present utility model.
