Abstract
The utility model relates to an ultra-filter pretreatment device of a reverse osmosis water purifier, which is provided with two or more than two sets of ultra-filters which are in parallel. A water outlet pipe of each parallel ultra-filter is directly connected with an inlet of a first-grade high pressure pump of a first-grade reverse osmosis device through a main pipe. The utility model has the advantages that one set of the parallel ultra-filter can be used for standby, and remained one or a plurality of sets is used, and thus normal production can not be affected because of back flushing or overhauling and the quality of pretreated water can be guaranteed to be stable and reliable. At the same time, the fluctuation of water flow can be smartly adapted. Though a set of the ultra-filter is added, a water storage tank, a booster pump and a security filter of the pretreated water are saved. Thus, general occupation areas of the utility model is reduced and process is shortened, and thus running cost can reduced and operations can further simplified.
Description
Technical field
The utility model relates to the ultrafiltration pretreatment device in a kind of reverse osmosis water purifier.
Background technology
At present, the pretreatment unit of reverse osmosis water purifier adopts more medium filter and activated charcoal filter etc. mostly, above-mentioned pretreatment unit is not only bulky, and operation is complicated, the working cost height, and Yuan Shui contain pollutent more, when water quality is relatively poor, often be difficult to reach pretreated requirement.For this reason, the applicant once developed and had applied for " the two-pass reverse osmosis pure water device of preposition ultra-fine filter " patent, substituted above-mentioned conventional filter with ultra-fine filter and made pretreatment unit, dwindled the volume of pretreatment unit effectively, and had improved the quality of pretreated water.But owing to still keep conventional pre-treatment water storage tank, topping-up pump and security personnel's filter in the ultra-fine filter back, therefore, flow process is still complicated, and whole floor space is still bigger.
Summary of the invention
The technical problem that the utility model quasi-solution is determined is: guaranteeing that pre-treatment water quality is reliable and stable, and under the prerequisite of energy adaptogen discharge fluctuation, simplifying the flowage structure of ultrafiltration pretreatment device, further dwindling floor space simultaneously.
Technical solution of the present utility model is: it is provided with two groups or more ultra-fine filter that is in parallel, and the ultra-fine filter rising pipe that respectively is in parallel directly is connected with the one-level high-pressure pump import of first-stage reverse osmosis device by house steward.
The beneficial effects of the utility model are: the ultra-fine filter that is in parallel is can one group standby, another group or several groups of uses, can or not keep in repair because of back flushing influences ordinary production, can guarantee the reliable and stable of pretreated water quality, the fluctuation of adaptogen discharge neatly simultaneously; Though device has increased by one group of ultra-fine filter, has save pretreated water water storage tank, topping-up pump and security personnel's filter, therefore to install overall floor space and reduce, flow process shortens, and operation is further simplified, and running cost reduces.
Description of drawings
Accompanying drawing is the utility model overall structure synoptic diagram.
Embodiment
The utility model is described in further detail with embodiment below in conjunction with accompanying drawing.
Present embodiment is provided with two groups of ultra-fine filters 1,2, all be provided with control valve 6 on the water inlet pipe of ultra-fine filter 1,2 and the rising pipe, raw water tubes 5 is connected in parallel with the water-in of ultra-fine filter 1,2, the rising pipe 3 of ultra-fine filter 1 and the water outlet of ultra-fine filter 24 join with outfall sewer 7, and outfall sewer 7 is connected with one-level high-pressure pump 8 imports of first-stage reverse osmosis device 9 again.
Claims (1)
1, a kind of ultrafiltration pretreatment device of reverse osmosis water purifier, has ultra-fine filter, it is characterized in that it is provided with the ultra-fine filter that two groups or more is in parallel, the ultra-fine filter rising pipe that respectively is in parallel directly is connected with the one-level high-pressure pump import of first-stage reverse osmosis device by house steward.
