Description
Technical field
The invention belongs to the application of membrane separation technology field, particularly a kind of at a kind of film thread bundling filling and transverse collector pipe hollow rotatable fiber film component.
Background technology
Membrane bioreactor is a kind of technology that membrane separation technique and biological sewage treatment technology are combined and dispose of sewage, compare with traditional biological sewage treatment technology, it has that floor space is little, anti impulsion load, Treatment of Sludge expense are low, be convenient to control automatically and have the advantages such as potentiality of upgrading, is considered to have most one of the sewage disposal of prospect and reuse technology.But membrane material cost height, problems such as the film silk easily pollutes, frangibility have seriously hindered further applying of membrane Bio-reactor Technology all the time.
Hollow-fibre membrane is a kind of design form of membrane module, has been applied to micro-filtration (MF), ultrafiltration (UF), gas separation (GP), counter-infiltration fields such as (RO) widely
[Xu Zhenliang. the embrane method water technology. Beijing, Chemical Industry Press, 2001]In sewage disposal, most hollow-fibre membranes pressure vessel of not packing into constitutes built-in membrane bioreactor but directly membrane module is put into reactor.
Hollow fiber film assembly is in long-time running, and the mechanical strength of membrane material is that can the decision membrane bioreactor stablize one of important decisive factor of good operation.Hollow fiber film assembly is in application process, and majority utilizes aeration to wash away to realize the control of film surface contamination and slows down.But in application in practice, the aeration of long term atmospheric amount washes away and has caused the fracture of wire situation of the glued root of hollow fiber film assembly serious, and especially the fracture of wire problem of assembly top bonded section has had a strong impact on the stable operation of membrane bioreactor.This is because in the membrane bioreactor running, membrane module bottom continues aeration, the fluid of turbulent fluctuation remains the film silk to rock back and forth the state of vibration, and the bending stress that long-time caudacoria silk root produces increases, and finally reaches the fatigue strength of film silk and ruptures.Therefore, hollow fiber film assembly is in the long-time running process, and strengthening the mechanical strength of membrane material and the structural design of optimization membrane module is a key factor of the stable good operation of decision membrane bioreactor.
Summary of the invention
, bonded section low at hollow fiber film assembly membrane material mechanical strength in engineering is used be the serious problem of assembly top glued district fracture of wire especially, the invention provides a kind of film thread bundling filling and transverse collector pipe hollow rotatable fiber film component, can effectively alleviate and improve this problem.Simultaneously, the invention provides a kind of mode of novel installation membrane module, be convenient to the disassembly, cleaning of assembly,, the good effect of improving is arranged also for hollow fiber film assembly integral replacing complexity, problem that intensity is big.
A kind of film thread bundling filling that the present invention is mentioned and transverse collector pipe hollow rotatable fiber film component, each sheet by the transverse tube that catchments (1) (transverse tube that catchments divide catchment transverse tube (1-1) and under the transverse tube (1-2) that catchments), the standpipe that catchments (2), aeration tube (3), film silk (4), fixedly transverse tube (5) etc. is formed.Adjacent two diaphragms of two rows by aeration tube (3), the transverse tube that catchments (1-1,1-2), the standpipe that catchments (2) is linked as a membrane module.It is characterized in that: the transverse tube that catchments (1) is in series by a plurality of threeways (6) or is a kind of moulding with a plurality of boundling film silks filling mouths of pipe transverse tube (1) that catchments.Hollow-fibre membrane be pencil respectively correspondence fill in the transverse tube that catchments (1-1) and the boundling film silk filling mouth of pipe of the transverse tube (1-2) that catchments down in.If the film tow has fracture can carry out single Shu Genghuan, and is very convenient, reduced the turnover rate of whole membrane module, thereby provided cost savings greatly.
Film thread bundling filling that the present invention is mentioned and transverse collector pipe hollow rotatable fiber film component, be meant membrane module up and down two transverse tubes that catchment (1-1 and 1-2) be connected short tube (7) arranged in the catchment mouth of pipe the inside of standpipe (2) one sides of access, being connected in the mouth of pipe that inserts aeration tube (3) one sides has pipe plug (9).Short tube (7) and pipe plug (9) transverse tube (1) that will catchment is respectively located to be connected at elbow (8) with aeration tube (3), the standpipe that catchments (2).The junction is connected by greasing substance (for example vaseline etc.), so both can seal, and can make the transverse tube that catchments (1) have rotation again.Simultaneously add a fixedly transverse tube (4), prevent because the two ends of the transverse tube that catchments are to be dynamically connected to cause the diaphragm as Fig. 4 to be deviate from membrane module top.
The transverse tube that catchments of membrane module can wash away down at aeration, rotates an angle to stable state, as shown in Figure 5 with the swing and the pulling of film silk.At this moment when the air water mixed flow washes the film silk, what the film silk mainly bore is pulling force, and bending stress reduces greatly, particularly the bending stress at film silk root reduces greatly, thereby effectively reduce the hunting frequency of film silk root and suffered bending stress, improve the anti-fatigue ability of film silk, prolong the service life of film silk, effectively prevent the fracture of film silk.
Remain with good flush liquid runner between two adjacent diaphragms of this membrane module, reduced the impulsive force of the suffered air water mixed flow of membrane module top-film silk, reduced the chance that mud is assembled between diaphragm.Because the single relatively film silk of boundling film silk intensity is bigger, this boundling film cortina assembly has alleviated the possibility of single film silk fracture.
The membrane material of film silk (4) can be an organic hollow fiber film material common on the various markets.
Film thread bundling filling that the present invention is mentioned and transverse collector pipe hollow rotatable fiber film component, can effectively improve and reduce because the local stress that aeration washes away film silk root, effectively solve the impact of air water mixed flow and cause film silk fracture of wire, membrane module integral replacing frequently to reach problems such as hollow-fibre membrane operating cost is bigger, make the organic film of the relatively low doughnut of mechanical strength in membrane bioreactor, have more extensively and good prospects for application.
