Abstract
The utility model discloses an offline medicinal-washing device of RO (Reverse Osmosis) membranes. The offline medicinal-washing device comprises a medicinal washing box, a medicinal washing pump, a precision filter, a high-pressure pump and an RO membrane shell which are communicated in sequence by pipelines, wherein the RO membrane shell can contain the RO membrane to be medicinally washed; the high-pressure pump is parallelly provided with a medicinal-washing branch pipe which is controllable in communication or blocked; the water inlet side of the RO membrane shell is communicated with the side of the high-pressure pump, and the water producing side and the sewage side of the RO membrane shell are respectively communicated to the medicinal washing box by pipelines; the water producing side of the RO membrane shell is also provided with a conductivity sensor. The offline medicinal-washing device disclosed by the utility model has the advantages that the structure is simple; a RO-membrane detecting function is endowed for the medicinal-washing device by the medicinal-washing branch pipe and a detecting system, one-stop type treatment of medicinal washing and detection can be achieved after the RO membranes are removed from the equipment, simultaneously a detecting function is added, and the detection can be carried out according to the setting, so that the medicinal washing time is greatly shortened, the medicinal washing efficiency is improved and the influence on operation of the whole device is reduced.
Description
Technical field
The utility model relates to water-treatment technology field, particularly relates to a kind of RO film off-line medicine cleaning device.
Background technology
At present, membrane separation technique is applied in a lot of fields, for example, and ultra-pure water manufacture, water conditioning boiler, food, medical concentrating, municipal sewage treatment, the recovery of utility in chemical waste liquid.But in daily larger reverse osmosis membrane system, even running is the target that each producer is pursued always, if counter-infiltration operation processing method is proper, will greatly extend the service life of anti-seepage membrane.Be 3 years the service life of film manufacturer general provision film, but can to reach 5-8 years even longer the life-span of film under good operation maintenance condition; But if regular maintenance is poor or to go wrong and take measures improperly, will have a strong impact on the operation of system, even some film operation some months, is just forced to change.
Regular maintenance mainly refers to that reverse osmosis membrane will regularly carry out medicine and wash and wash, there is in the market reverse osmosis membrane chemical cleaning online device, but this kind of way, in the time of can making reverse osmosis transdermal wash, equipment cannot produce water, so not only delay the use of equipment, and the medicine time of washing compared with off-line, clean longly, effect is poor.Reverse osmosis membrane is removed, then pack this equipment into, carrying out film list props up medicine and washes, can be according to the pollution condition of every film, the medicine time of washing is carried out to suitable adjustment, reduce unnecessary resource consumption, but existing off-line medicine cleaning device complex structure and lack testing agency, the RO state after can not direct-detection medicine washing.
Utility model content
The purpose of this utility model is for the technological deficiency existing in prior art, and a kind of RO film off-line medicine cleaning device is provided.
For realizing the technical scheme that the purpose of this utility model adopts, be:
A kind of RO film off-line medicine cleaning device, comprise that medicine tank-washer, the medicine of connection are washed pump, accurate filter, high-pressure pump and can will treat that the RO film that medicine is washed holds RO putamina wherein by the road successively, described high-pressure pump is arranged in parallel the medicine of controlled conducting or cut-off and washes branch road, the influent side of described RO putamina is communicated with high pressure pump side, produce water side and sewage side and be communicated to by the road respectively medicine tank-washer, in the product water side of described RO putamina, be also provided with conductivity sensor.
Described RO putamina is a plurality of being arranged in parallel.
Described RO putamina comprises 4 cun of putaminas and 8 cun of putaminas.
On the product water side of described RO putamina and the pipeline of sewage side, be provided with flowmeter and pressure gauge.
Compared with prior art, the beneficial effects of the utility model are:
RO film off-line medicine cleaning device of the present utility model, simple in structure, by medicine, wash branch road and detection system gives medicine cleaning device a RO film measuring ability, after removing in equipment, can accomplish RO film that medicine washes and detect one-stop processing, increase measuring ability simultaneously, can detect by setting, greatly shorten medicine and wash the time, improve medicine and wash efficiency, for having shortened the impact on complete machine operation.
Accompanying drawing explanation
Figure 1 shows that water treatment facilities structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, RO film off-line medicine cleaning device of the present utility model, comprise the medicine tank-washer 1 being communicated with by the road successively, medicine is washed pump 2, accurate filter 3, high-pressure pump 4 and can will treat that the RO film that medicine is washed holds RO putamina 5 wherein, described high-pressure pump is arranged in parallel the medicine of controlled conducting or cut-off and washes branch road 6, the influent side of described RO putamina is communicated with high pressure pump side, produce water side and sewage side and be communicated to by the road respectively medicine tank-washer, product water side at described RO putamina is also provided with conductivity sensor, on the described product water side of RO putamina and the pipeline of sewage side, be provided with flowmeter and pressure gauge simultaneously, influent side at described RO putamina is also provided with pressure gauge.
In described medicine tank-washer, be provided with reverse osmosis membrane scavenger specially, can know operating mode and select cleaning agent targetedly, it is that medicine elution is for power that described medicine is washed pump, carrying out medicine while washing, high pressure air pump inoperative, only depend on medicine to wash pump and through medicine, wash branch road and liquid is pumped into RO film in RO putamina and carry out medicine and wash, when medicine is washed, the product water of RO film and waste water are all back to medicine tank-washer.Described accurate filter, in order to the trace suspension granule foreign in dewatering, prevents from the cleaning of film to impact.Accurate filter (being called again cartridge filter), shell adopts the manufacture of UPVC material, and filter core is that polyethylene melts and sprays material, and filtering accuracy is 5 μ m, and former water is under pressure by filter core, and particulate, the impurity removed in water are held back, and reach clean-up effect.
After film has cleaned, medicine is washed the controlled cut-off of magnetic valve on branch road, simultaneously high-pressure pump is started working provides required motive force for RO membrane filtration, the detected values such as flow, pressure that simultaneously produce water side and sewage side by RO film directly judge that medicine washes effect, directly liquid is carried out to RO membrane filtration testing result, simplified operation.
As preferred version, described RO putamina is a plurality of being arranged in parallel, and preferably, described RO putamina comprises 4 cun of putaminas and 8 cun of putaminas, can be packed in corresponding putamina and clean according to the size of reverse osmosis membrane.
The above is only preferred embodiment of the present utility model; it should be noted that; for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
