Abstract
The utility model relates to a water-saving type reverse osmosis apparatus, comprising a first-level original water tank, a first-level high-pressure pump, a first-level reverse osmosis membrane apparatus, which are connected in a pipeline order, and a reverse osmosis apparatus which comprises a water producing tank. The utility model is characterized in that: a concentrated water reflux pipe is led out to the original water tank in front of a control valve of a concentrated water discharging pipe of the first-level reverse osmosis membrane apparatus. The concentrated water reflux pipe is provided with the control valve. The concentrated water is changed to partial discharging and partial reflux utilization from the original whole discharging by the utility model. When the yielding water quality is ensured to keep in an acceptance limit, the availability of the original water is improved by about 10%. The utility model greatly reduces production cost, and saves the original water.
Description
Technical field
The utility model relates to a kind of water treatment device of reverse osmosis membrane, especially first-stage reverse osmosis embrane method desalting plant.
Background technology
It is comparatively general to use reverse osmosis membrane apparatus to make de-salted water at present, it has advantages such as water quality treatment wide ranges, effluent quality are good, but the shortcoming that existing first-stage reverse osmosis film desalting plant exists is that the dense water that produces in the production process all is not utilized and discharges, therefore, the utilization ratio of former water is lower.
Summary of the invention
The purpose of this utility model mainly is to carry out technological improvement on the basis of the common first-stage reverse osmosis film desalting plant that is made of high-pressure pump, reverse osmosis membrane,, reduces production costs the water resources of saves valuable simultaneously to improve the utilization ratio of former water.
Technical solution of the present utility model is: in the first-stage reverse osmosis desalting plant of being made up of the raw water box that is linked in sequence with pipeline, one-level high-pressure pump, first-stage reverse osmosis film device and product water tank, pick out the concentrate recirculation pipe to raw water box or one-level high-pressure pump from drawing before the control valve of first-stage reverse osmosis film device concentrated water discharge pipe especially, this concentrate recirculation pipe is provided with control valve.
The utility model changes dense water into partial discharge and partial reflux utilization by original all dischargings.Facts have proved, under identical water inlet condition, guarantee the output quality in qualified indication range, can make former water use efficiency improve about 10%, reduced production cost greatly, saved former water resources.
Description of drawings
Accompanying drawing is the utility model overall structure synoptic diagram.
Embodiment
The utlity model has and the essentially identical composition structure of common first-stage reverse osmosis film desalting plant.As accompanying drawing, send into raw water box 3 as former water 1 through pipeline 2 from the pretreated water that pretreatment system obtains, former water 1 is delivered to first-stage reverse osmosis film device 7 by raw water box outlet pipe 4, one-level high-pressure pump 5, one-level high-pressure pump outlet pipe 6, after first-stage reverse osmosis film device 7 is handled, output water is delivered to by pipeline 8 and is produced water tank 9, and the dense water of output drains into dense pond 11 by delivery pipe 10; The utility model is then drawn a concentrate recirculation pipe 12 and is connected to raw water box 3 before the control valve of concentrated water discharge pipe 10, and on concentrate recirculation pipe 12 control valve is set.
Be the utility model and common first-stage reverse osmosis film device condition of production synopsis below:
Can find out that from last table (quality index is under the situation of water conductivity≤10us/cm) the more common first-stage reverse osmosis film device water saving 10% of the utility model in identical working condition and output qualified water.
