Abstract
The utility model relates to an osmosis membrane cleaning system of a one-stage reverse osmosis filtering device, which comprises a one-stage membrane element. A first water inlet and a second water outlet are arranged at the front end of the membrane element, a first water outlet and a second water inlet are arranged at the rear end of the membrane element, a control valve is respectively arranged on the first water inlet, the first water outlet, the second water inlet and the second water outlet, wherein, the first water inlet and the first water outlet are combined to form a first water way for introducing water to be filtered, and the second water inlet and the second water outlet are combined to form a second water way for introducing cleaning liquid, and the flow direction of the liquid in the first water way is opposite to that of the liquid in the second water way. The flow direction of the cleaning liquid is set to be opposite to that of the water to be filtered through reliably adjusting the flow direction of the cleaning liquid, not only the soluble dirt can be cleaned, but also the undissolved suspended substances can be cleaned away through the original inlet position, and the more complete and thorough effect is realized.
Description
Technical field
The utility model relates to the cleaning equipment art of reverse-osmosis filtering device, refers in particular to a kind of permeable membrane purging system of unistage type reverse-osmosis filtering device.
Background technology
At present, reverse-osmosis filtering device is widely used in urban drinking water, industrial process waters and useless water reuse.Its adopted have low energy consumption, no phase transformation, pollution-free, and separative efficiency, membrane filtration technique that cycles of concentration is high wherein utilize suitable film to separate to concentrate the washings of electroplate liquid etc., cycles of concentration can reach 100 times (by volumes).Concentrate after film separates is got back to electrolytic cell after suitably handling the nickel ion concentration that reaches certain, promptly reclaim nickel, the liquid that sees through of film system is that pure water can directly be got back in the washing trough of plating piece, realized the zero-emission of electroplating wastewater processing, not only can not cause secondary pollution, but also reclaimed the harmful heavy metal in the waste water, and change harmful to treasure, water resource is reused.
Reverse-osmosis filtering device includes multiple permeation filtration design such as unistage type, two-part and multisection type, and permeable membrane is the most important parts of reverse-osmosis filtering device.Wherein, the unistage type permeation filtration one-level that is otherwise known as concentrates, and its regular meeting in the process that reality is used deposits many dirts or suspension in membrane component.By this, for keeping its normal running, need regularly it to be cleaned.Yet traditional cleaning method is that the flow direction in cleaning fluid water route is with to be filtered flowing to of water water route identical, owing to be filtered water after membrane component filters, the dirt or the suspension that are filtered in the water are deposited on the inflow side that is filtered water in the membrane component usually, if still cleaning fluid is injected by its inflow side, those can be dissolved dirt can be flushed away through membrane component, but those are failed dissolved suspension and then still can rest on the inflow side of membrane component, and can not will thoroughly wash.So, cleaning performance is undesirable.
The utility model content
The utility model is at the defective of prior art existence, main purpose provides a kind of permeable membrane purging system of unistage type reverse-osmosis filtering device, the flow direction of its cleaning fluid is set to opposite direction with the flow direction that is filtered water, mat and obtain better cleaning performance.
For achieving the above object, the utility model adopts following technical scheme:
A kind of permeable membrane purging system of unistage type reverse-osmosis filtering device, comprise the unistage type membrane component, the front end of this membrane component is provided with first water inlet and second delivery port, the rear end of membrane component is provided with first delivery port and second water inlet, this first water inlet, first delivery port, be respectively arranged with a control valve on second water inlet and second delivery port, wherein, first water inlet and first delivery port are combined to form and are used to feed first water route that is filtered water, this second water inlet and second delivery port are combined to form second water route that is used to feed cleaning fluid, and first water route is opposite with flow direction in second water route.
The utility model is compared with technology with existing, its beneficial effect is, flow direction by reasonable adjustment cleaning fluid, it is opposite with the flow direction that is filtered water that the flow direction of cleaning fluid is set to, not only diffluent Fouling Cleaning can be fallen, but also the not dissolved suspension of part can be washed via its original inflow place, reach more complete, cleaning performance more completely.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
Demonstrated structure with reference to Fig. 1 as the preferred embodiment of the utility model, comprise unistage type membrane component 30, the front end of membrane component 30 is provided with first water inlet 11 and second delivery port 22, and the rear end of membrane component 30 is provided with first delivery port 12 and second water inlet 21.
Wherein, first water inlet 11 and first delivery port 12 are combined to form first water route 10 that internal liquid flows from left to right, and this first water route 10 is used for importing and is filtered water, usually, this is filtered water after flowing through membrane component 30, deposits many dirts or suspension 40 in the inflow side 31 of membrane component 30.
Second water inlet 21 and second delivery port 22 are combined to form second water route 20 that internal liquid flows from right to left, and promptly this second water route 20 is opposite with the flow direction of liquid in first water route 10.This second water route 20 is used to import various cleaning fluids, for example acidity or alkaline cleaner, and cleaning at dirt in the aforementioned films element 30 or suspension 40, this cleaning process is filtered and just carries out after finishing at the aforementioned water that is filtered usually.
Be respectively arranged with control valve 50 on aforementioned first water inlet 11, first delivery port 12, second water inlet 21 and second delivery port 22, this control valve 50 is used to control aforementioned first water route 10 and alternative expression work is done in second water route 20, when being filtered the filtration of water, control valve 50 on this first water inlet 11 and first delivery port 12 is opened, i.e. 10 conductings of first water route; Simultaneously, the control valve 50 on second water inlet 21 and second delivery port 22 is closed, and promptly second water route 20 is closed.When carrying out the cleaning process of permeable membrane, the control valve 50 on this first water inlet 11 and first delivery port 12 is closed, and promptly first water route 10 is closed; Simultaneously, the control valve 50 on second water inlet 21 and second delivery port 22 is opened, i.e. 20 conductings of second water route.
Of the present utility model focusing on, flow direction by reasonable adjustment cleaning fluid, it is opposite with the flow direction that is filtered water that the flow direction of cleaning fluid is set to, not only diffluent Fouling Cleaning can be fallen, but also the not dissolved suspension of part can be washed via its original inflow place, reach more complete, cleaning performance more completely.
