At present, the patent about hyperfiltration membrane assembly is the most both at home and abroad, but hyperfiltration membrane assembly product with single tube water distribution is Main, such as 2010 Chen Hong praise a kind of of invention and have the polysulfone hollow fiber ultrafiltration membrane system improving central duct structure, this device Mainly include end cap, centre pipe, bearing shell etc., have similarity in this patent, but multitube water distribution, water distribution cannot be realized The target calls such as uniform and high membrane flux.Other hyperfiltration membrane assembly patents also have CN201310159824.9, The series of patents such as CN201320637410.8, but these patents all cannot realize uniform, the high membrane flux of multitube water distribution etc. simultaneously Target call.
Summary of the invention
The present invention needs the problem solved to be for above-mentioned the deficiencies in the prior art, and provides a kind of simple in construction energy real Existing multitube water distribution, water distribution be uniform and the polysulfone hollow fiber ultrafiltration membrane system of the multitube water distribution of high membrane flux.
For solving above-mentioned technical problem, the technical solution used in the present invention is:
The polysulfone hollow fiber ultrafiltration membrane system of a kind of multitube water distribution, it includes cylindrical shell, and the two ends up and down of cylindrical shell set respectively Having upper end cover and bottom end cover, be filled with hollow cellulose film silk in cylindrical shell, bottom end cover is provided with former water water inlet pipe, upper end cover Being provided with dense water outlet pipe and water purification outlet, hollow cellulose film silk one end connects former water water inlet pipe, and the other end connects dense water Outlet pipe, bottom end cover is embedded with PVC water distributor group, and PVC water distributor group includes Large Diameter Pipeline PVC water distributor and at least pipe with small pipe diameter PVC water distributor, is additionally provided with aeration opening at bottom end cover, aeration opening is connected with aerator.
Raw water inlet and water purification outlet are positioned at the same side of cylindrical shell.
The quantity of pipe with small pipe diameter PVC water distributor is 5, and annular is distributed on around Large Diameter Pipeline PVC water distributor.
The tube wall of PVC water distributor group has square opening, and the aperture of square opening is 8 mm.
Being coated respectively with encapsulating layer on upper end cover and bottom end cover, former water water inlet pipe is fixed on the encapsulating layer of bottom end cover, dense water Outlet pipe embeds in the encapsulating layer of upper end cover, and hollow cellulose film silk is fixed in the encapsulating layer of upper end cover, bottom end cover.
Compared with prior art, the invention has the beneficial effects as follows: the pending former water PVC water distributor by different tube diameters The longitudinal direction former water ventilating water pipe of composition enters in membrane module, reaches multitube water distribution, the uniform effect of water distribution, then is filled by aeration The aeration backwash effect put, thus produces the shake of hollow cellulose film silk so that the macromolecular particle thing in former water is by mistake Filtering, and then reach purifying water body and increase the effect of membrane flux, the dense water after process is discharged through overrich water outlet pipe, processes After clean water through water purification outlet export.
