Abstract
The utility model discloses a reverse osmosis or nanofiltration concentrated water recovery device for a pipeline direct drinking water treatment system. The recovery device is characterized in that an ultrafiltration membrane component is adopted to serve as a device main body; the reverse osmosis or nanofiltration concentrated water enters from one end of the ultrafiltration membrane component via a central distribution pipe; a water inlet pressure gauge and a water inlet control valve are arranged on the water inlet side of the recovery device; a water outlet pressure gauge, a water outlet control valve and a water outlet flow meter are arranged on the water outlet side of the recovery device; and a drainage pressure gauge, a drainage control valve and a drainage flow meter are arranged on the drainage side of the recovery device. The reverse osmosis or nanofiltration concentrated water recovery device has the advantages of reasonable structure and skillful concept, can recover most of discharged reverse osmosis or nanofiltration concentrated water, and improves the utilization ratio of water resources, thereby having popularization values.
Description
Technical field
The utility model relates to a kind of reverse osmosis or the dense apparatus for recovering of nanofiltration, is applied in the dense water of piped direct-drinking water treatment system and reclaims, and improves former water use efficiency.
Background technology
" direct-drinking water pipeline system is tackled former water and is carried out the deep purifying processing according to " direct-drinking water pipeline system technical regulation " (CJJ 110-2006) 4.0.1 bar." and 4.0.4 bar " deep purifying is handled should adopt membrane technology "; at present; the direct-drinking water pipeline system deep purifying is handled and used nanofiltration membrane or reverse osmosis membrane technology greatly; when the drinking-water quality gets a promotion, need discharge the dense water that accounts for the about 30-50% of former water inventory in process of production." rules " 4.0.8 bar " the dense water of advanced purification treatment system discharge should be recycled ", but lack ready-made dense apparatus for recovering again because dense water recovery value is low, most of dense water directly discharges, and causes the waste of water resources.
Summary of the invention
The purpose of this utility model is, directly discharge the water resource waste that causes in order to overcome the existing dense water of piped direct-drinking water treatment system, provide a kind of reverse osmosis or nanofiltration dense apparatus for recovering, this device utilizes the overbottom pressure of the dense water of discharging, directly in the dense waterpipe of the row of being serially connected in, treated recyclable dense water more than 70%.
For achieving the above object, the utility model adopts following technical scheme: the dense apparatus for recovering of reverse osmosis of piped direct-drinking water treatment system or nanofiltration, it is characterized in that: the employing hyperfiltration membrane assembly is an apparatus main body, the dense water of reverse osmosis or nanofiltration enters through the central dispense pipe from ultra-filtration membrane one end, influent side at retrieving arrangement, be provided with inlet gage and water inlet control valve, water outlet side is provided with discharge pressure table, outlet water control valve and water flow meter, and drain-side is provided with water discharge pressure table, draining control valve and drain discharge meter.
Because adopt such scheme, be not difficult to draw as drawing a conclusion: the utility model is rational in infrastructure, be skillfully constructed, can discharge dense water to most reverse osmosis or nanofiltration and reclaim, improve water utilization rate, have promotional value.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Accompanying drawing 1 is a process flow diagram of the present utility model.
Accompanying drawing 2 is product assembling synoptic diagram of the present utility model.
Accompanying drawing 3 is product assembling synoptic diagram of the present utility model.
Embodiment
The dense apparatus for recovering of reverse osmosis of piped direct-drinking water treatment system or nanofiltration, adopting ultra-filtration membrane (4) assembly is apparatus main body, the dense water of reverse osmosis or nanofiltration enters through the central dispense pipe from ultra-filtration membrane (4) one ends, under pressure, solvent in the dense water or small molecules see through ultra-filtration membrane (4) becomes the recycling of ultrafiltration water; Most of material, colloidal solid and bacterium etc. are trapped within ultra-filtration membrane (4) internal surface, and discharge with draining.At the influent side of retrieving arrangement, be provided with inlet gage and water inlet control valve (2), in order to grasp intake pressure and to regulate flooding velocity; Water outlet side is provided with discharge pressure table, outlet water control valve (5) and water flow meter (6), in order to grasp discharge pressure and to adjust discharge; Drain-side is provided with water discharge pressure table, draining control valve (8) and drain discharge meter (9), in order to grasp water discharge pressure and to regulate drain discharge.
When reverse osmosis or nanofiltration concentrated water drainage water pipe (1) draining need be reclaimed, open water inlet control valve (2) UNICOM's water inlet pipe (3), dense water is handled through ultra-filtration membrane (4), water outlet enters reverse osmosis or the reuse of nanofiltration treatment system intermediate water tank by adjusting water control valve (5) through water flow meter (6) and rising pipe (7); Ultra-filtration membrane (4) draining is by regulating draining control valve (8), through drain discharge meter (9) and water shoot (10) discharging.Every operation some cycles as 10 hours, is tackled dense apparatus for recovering and is just washed.When just washing, complete opening water intaking valve (2) and draining control valve (8), close outlet water control valve (5), carry out the full flow flushing, washed 10 minutes at every turn.
