Abstract
The utility model relates to a water-saving device of a water treatment system for hemodialysis, which can be used in a water treatment system which utilizes a reverse osmosis device to make dialysis water. The utility model is characterized in that the water-saving device of a water treatment system for hemodialysis comprises a discarded softening water storage tank and a constant pressure pump for the tank, wherein, the discarded softening water storage tank is provided with an upper limit water level control valve and a lower limit water level control valve. The discarded softening water storage tank is connected with reverse osmosis discarded water of a reverse osmosis machine of the system by pipelines. Water of the discarded softening water storage tank is connected with a water inlet pipe of the reverse osmosis machine by the constant pressure pump for the tank through pipelines. The utility model can save water largely, and can be used as emergency equipment for temporary water shutoff.
Description
This utility model relates to a kind of water saving fixtures.
China has about 4000 of various types of haemodialysis control units at present, most units use reverse osmosis mechanism to make water for dialysis, because a water for dialysis of the every making of reverse osmosis machine of this type will abandon 4-5 part demineralized water, lose about 1,000,000 tons of demineralized water national every year.Although it is few that water rate price and the other fees in the whole dialysis procedure are compared proportion, because the many big and medium-sized cities of China are hydropenia cities, and haemodialysis control unit concentrates in these big and medium-sized cities relatively, so problem of water saving is extremely urgent.
At the problems referred to above, the purpose of this utility model is to provide a kind of water saving fixtures simple in structure for the hemodialysis water treatment system.
For achieving the above object, this utility model is taked following design: a kind of water saving fixtures of hemodialysis water treatment system, it is applied in and utilizes the reverse osmosis device to make in the water treatment system of water for dialysis, it is characterized in that: it comprises and abandons the demineralized water holding vessel, the jar constant pressure pump, described abandon have on the demineralized water holding vessel on, the lower limit altitude valve, the described demineralized water holding vessel that abandons is connected by the demineralized water that pipeline and reverse osmosis machine in the described system abandon, described jar of water inlet pipe that by pipeline the described water that abandons the demineralized water holding vessel is connected to described reverse osmosis machine with constant pressure pump.
This utility model since the demineralized water that the reverse osmosis machine is abandoned after abandoning the demineralized water holding vessel and storing, feed the reverse osmosis machine again, make reverse osmosis abandon water and be recycled (circulation does not reach 3 times under the normal operation, is used up) 3-4 time, for making water for dialysis, reached water-saving purpose.Because the used water of multiplexing machine of flushing dialyser only requires it is demineralized water, therefore will feed multiplexing machine simultaneously, can further save the water source through the demineralized water that recycles.Be in patient's dialysis procedure in addition,, can also utilizing the demineralized water making water for dialysis of storage to continue as patient's dialysis, and be unlikely to interruption of work if barrier is cut off the water suddenly for some reason.Show with clinic trial that after tested the water for dialysis that uses this utility model to make meets the water for dialysis standard, clinically do not see untoward reaction, utilize circulation to abandon the dialyser that demineralized water enters the multiplexing machine flushing, also can reach clinical use standard.Especially this utility model suitably increases the activated carbon and the resin device of reverse osmosis mechanism water treatment system, can not influence the service life of the anti-seepage membrane of reverse osmosis machine fully.This utility model can be widely used in various the utilization in the hemodialysis water treatment system that reverse osmosis mechanism makes water for dialysis.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.
Fig. 1 is this utility model structural representation
As shown in Figure 1: in existing hemodialysis water treatment system, increase by one and abandon demineralized water holding vessel 1, connect a constant pressure pump 2 identical at the outlet that abandons demineralized water holding vessel 1 with constant pressure pump pressure in the original system, hydraulic pressure does not change like this, to the anti-seepage membrane in original reverse osmosis machine 3 yet just not influence.Constant pressure pump 2 is communicated with the inlet pipeline of reverse osmosis machine 3 by pipeline 4, the water inlet that abandons demineralized water holding vessel 1 is abandoned water by pipeline 5 with the reverse osmosis of reverse osmosis machine 3 be communicated with.Upper and lower limit altitude valve 6,7 is set abandoning on the demineralized water holding vessel 1, a pipeline 9 that leads to multiplexing machine 8 in original dialysis machine in parallel again on pipeline 4.In parallel connection place, a control valve 10,11 is installed respectively.A water pot water discharger 12 is set abandoning demineralized water holding vessel 1 top, makes provision against emergencies, under normal circumstances, water can not overflow.
In the foregoing description, control valve 6,7,10,11 can be manual, also can be electronic, perhaps uses electronicly generally speaking, uses manual during temporary needs.
The time marquis of work, the reverse osmosis of discharging in the reverse osmosis machine 3 abandons water and enters demineralized water holding vessel 1, when water level arrives upper limit water level, the control valve 11 of upper limit altitude valve 6 and pipeline 4 is opened (control valve 10 of pipeline 9 is closed at this moment) automatically, constant pressure pump 2 is started working, and cyclic softening water 4 enters the 3 continuation uses of reverse osmosis machine by the road.When water level reached the lower limit water level, control valve 11 was closed, and reverse osmosis machine 3 continues to use the water supply in the original system.When multiplexing machine 8 needed water, 4 the control valve 11 of can blinding off a line was opened the control valve 10 of pipeline 9, and recirculated water enters multiplexing machine 8.
