Abstract
The utility model relates to a washing of membrane bioreactor membrane specifically is membrane case online cleaning device. Have folding water tank in the constitution, the peripheral interval distribution of case mouth of folding water tank hangs the ring, folds the cavity size of water tank and treats an abluent list membrane case phase -match. The utility model discloses can utilize the changeability of self, soft shape makes its bottom that can be sent to arbitrary membrane case in the membrane cisterna by convenient quilt, and the suit is on the membrane case, single the isolation of membrane case in the membrane cisterna of online running has been realized with extremely simple and efficient mode, wash, current online cleaning mode had both been overcome and washing water and the big disadvantage of dose consumption that interior all the membrane casees of membrane cisterna lead to must be washd simultaneously, it moves and tears open not have the water treatment that the current off -line mode of wasing must the stopper film case again, the trouble of dress membrane case, it is short still to have simultaneously the scavenging period, high efficiency, good cleaning effect, water conservation festival medicine, the structure is extremely simple, simple operation, low in cost is showing there is the advantage, suitable online cleaning device as membrane bioreactor mesolamella case uses.
Description
Technical field
The utility model relates to the cleaning of membrane bioreactor film, is specially film case on-line cleaning device.
Background technology
In membrane bioreactor (hereinafter referred to as MBR), the cleaning way of film can be divided into off-line to clean and on-line cleaning substantially.
The cleaning of off-line cleaning for realizing single film case in membrane cisterna, cleaning performance can be ensured, when shortcoming is dismounting film case, a whole set of MBR system needs shutting down twice, and need crane to coordinate dismounting, during cleaning charge, bothersome, film case Offtime is long, usually needs 16-24 hour, therefore greatly affect MBR and normally run aquifer yield, larger on enterprise's downstream water demand impact.
On-line cleaning can realize the cleaning of whole membrane cisterna, and cleaning efficiency is higher, but cleaning performance is not as off-line cleaning.In cleaning process, the multiple film casees in same membrane cisterna must clean simultaneously, such as, have six groups of film casees in a membrane cisterna, must clean in the lump these six groups of film casees simultaneously.Must first by emptying for the mud in membrane cisterna during cleaning, then with dosing pump cleaning institute with medicament squeezed in membrane cisterna and soak membrane module.Membrane cisterna volume is large, the required cleaning water yield and reagent consumption large.
Utility model content
The purpose of this utility model is defect for above-mentioned off-line, on-line cleaning mode and provides a kind of device that can carry out on-line cleaning under MBR system does not stop transport prerequisite to single group film case.
For reaching above object, the technical scheme that the utility model is taked is:
A kind of film case on-line cleaning device, comprises foldable water tank, and the case mouth peripheral intervals distribution hanging ring of foldable water tank, cavity size and the single film case to be cleaned of foldable water tank match.
Above-mentioned film case on-line cleaning device, described foldable water tank top is rectangle, and bottom is circular arc, and first described hanging ring is distributed in 4 jiaos, rectangle, and then spaced apart between adjacent suspension ring.
Set up hanger bar in above-mentioned film case on-line cleaning device, the shape of cross section of described hanging ring and hanger bar matches, and collar extension footpath is greater than bar bore.
Y shape isocon is set up, respectively with valve on two diverter branch in above-mentioned film case on-line cleaning device.
Above-mentioned film case on-line cleaning device, described foldable water tank is that PVC presss from both sides net adhesive plaster material.
The utility model puies forward the changeability that can utilize himself, soft shape can be sent to the bottom of any film case in membrane cisterna easily, and be sleeved on film case, the isolation of single film case in membrane cisterna of on-line operation is achieved in extremely simple and efficient mode, cleaning, both overcome existing on-line cleaning mode and must clean rinse water that in membrane cisterna, all film casees cause and the large disadvantage of dose consumption simultaneously, do not exist again existing off-line cleaning way must stopper film case water treatment run and tear open, the trouble of dress film case, also there is scavenging period simultaneously short, efficiency is high, cleaning performance is good, water saving joint medicine, structure is extremely simple, easy and simple to handle, cheap remarkable advantage, the suitable on-line cleaning device as film case in membrane bioreactor uses.
Accompanying drawing explanation
The utility model has following accompanying drawing:
Fig. 1 the utility model example structure schematic diagram.
In figure: 1-foldable water tank, 2-hanging ring, 3-Y shape isocon, 4-penstock, 5-medicine valve, 6-film case.
Detailed description of the invention
Below in conjunction with accompanying drawing and illustrated embodiment, the utility model is described in further detail.
As shown in Figure 1 in embodiment, the peripheral rectangle frame with arcuate bottom is foldable water tank 1, and the rectangular hexahedron in it is film case 6.First hanging ring 2 is distributed in corner, spaced apart along short rectangular edges afterwards.When cleaning uses, first rope is hung on hanging ring 2, the water tank of folding flat body shape is put into membrane cisterna water, opens case mouth by the tractive of rope and entangle film case 6, lifting water tank afterwards makes case mouth expose the membrane cisterna water surface, and film case 6 and water segregation in membrane cisterna just come by foldable water tank 1.Now, can hanger bar (not showing in figure) be penetrated in the hanging ring 2 of rectangular box mouth, by hanger bar, foldable water tank 1 is suspended on the intrinsic spandrel girder of film case in membrane cisterna.
Still consult Fig. 1.Complete foldable water tank to after the suit suspension of film case single in membrane cisterna, by the penstock 4 on Y shape isocon 3, the membrane cisterna water in case is extracted, the clean water of band pressure can be adopted to wash out the foreign material such as the mud on film surface depending on the stifled situation of film dirt, rinse water of reinjecting also is cleaned film case after adding medicament by medicine valve 5.After cleaning, make hanger bar depart from spandrel girder, extract hanger bar and make water tank dive by rope is folding, departing from the film case 6 cleaned up, be set with the next one afterwards again and do not clean film case.Repeat successively, just can complete the on-line cleaning one by one of multiple film case in membrane cisterna.
Still consult Fig. 1.The utility model is not limited to the rectangle in figure shown in embodiment, can also be circular, square etc.Hanger bar can adopt steel pipe, and hanging ring can be the annulus of coupling, and ring internal diameter should be greater than pipe external diameter, and the length of bar should be greater than the length of side on the long and short limit of rectangular box mouth, to facilitate crane suspention and the suspension on spandrel girder.Penstock 4 place diverter branch can be connected on film case and produce water valve in the pipeline of film case, and pipeline can external scavenging pump, and medicine valve 5 place diverter branch can connect medicine system.Also to find time activated sludge in water tank by sludge pump during cleaning.The also unholiness situation of visual film case, utilizes the existing aerating system of film case to carry out aeration scrubbing to film case when needed.
Still figure consults 1.Foldable water tank can adopt PVC to press from both sides net adhesive plaster material and make.Y shape isocon and penstock, medicine valve can be used as matching component and purchase together with water tank, and idle another accessory also can be utilized at cleaning Assembling.
