Description
Technical field
The utility model relates to water-treatment technology field more particularly to a kind of water for dialysis processing systems.
Background technique
Water treatment system mainly includes the filter device that the water sources such as tap water, well water or river water are filtered into raw water, and
It is net water purifying means by purificating raw water.Filter device mainly includes the quartz filter being sequentially communicated, active carbon filtering
Device and the internal water softener for being filled with resin cation, water softener are mainly used for the calcium ion in water removal, prevent raw water net
Disguise and forms calcium carbonate on the reverse osmosis membrane set and fouling results in blockage.The principle of water softener removal calcium ion is to utilize to be adsorbed on
The higher sodium ion of activity on resin cation surface to occur to replace with calcium ion to react, due to being adsorbed on resin cation table
The sodium ion in face is eventually completely consumed, it is therefore desirable to by injecting saturated brine on time into water softener, that is, be saturated chlorine
Change sodium solution, to supplement the sodium ion on resin cation surface.
The process of supplement sodium ion is properly termed as regenerative process, usually mainly comprises the following steps: backwash, that is,
The filter residue flushing on resin cation surface is exhausted；It inhales salt to wash slowly, that is, the saturated brine in dissolved salt case is slowly sucked soft
It in hydrophone tank body, sucks on one side, on one side chemically reacts saturated brine and the intracorporal resin cation of tank, inhale sodium ion
It is attached to resin surface；It just washes, that is, is rinsed the salt water of previous step sucking tank body and by SS saline soaked resin cation
Completely；Moisturizing, that is, to moisturizing in dissolved salt case, in case regeneration uses next time.After regeneration ending, just enter normal water supply shape
State.
But in regenerative process, due to needing normal water source and power supply supply, if there is cutting off the water or hydraulic pressure is too low
The case where, or the case where have a power failure after inhaling salt and washing step slowly, or since the failsafe valve in water route causes just to wash
Situations such as effect is not in place is likely to cause to be increased by filter device supplied to the raw water salt content of purification device, Jin Erzao
It all declines to a great extent at subsequent water purification water quality and water rate.And for the water treatment system in particular for hemodialysis apparatus, only
If water water quality and water rate cannot be guaranteed, extreme influence will be brought to dialysis treatment.

It the case where group, can be with effective protection reverse osmosis membrane.
Further, temperature sensor is provided on the raw water box, the temperature sensor is electrically connected with the control device
It connects.
Beneficial effect using above-mentioned further scheme is: since dialysis machine there are certain requirements water purification temperature, when more
There was only several in platform dialysis machine at work, such as night emergency pattern has a large amount of remaining water purification in this way and returns
To raw water box, by water pump repressurization, these water are given birth to the water pump on reverse osmosis treatment component, pipeline, valve friction again
Heat, by rubbing repeatedly, after certain time accumulation, the temperature that will lead to raw water box and water purification is increased, and influences dialysis treatment.It is logical
Excess temperature sensor detects the temperature of raw water in raw water box, when raw water temperature exceeds a certain range, can carry out respective handling, with
Guarantee that water purification is in suitable temperature range.
Further, it is provided on the inlet pipeline into water motor-driven valve, the water inlet motor-driven valve and control device electricity
Connection.
Beneficial effect using above-mentioned further scheme is: by the flow of inlet water in adjusting raw water inlet pipeline, such as
Raw water when the temperature is excessively high, increases flow of inlet water in raw water box, makes the unit time interior room temperature water entered in raw water box more,
The temperature inside the box can be reduced to a certain extent, and then guarantees that water purification temperature is in OK range.
