Specific embodiment
To make the technical solution of the utility model and advantage clearer, the utility model is implemented below in conjunction with attached drawing
Mode is described in further detail.
The utility model embodiment provides a kind of circular water treating system for filter both soluble salt, as shown in Figure 1, this is followed
Ring water treatment system includes water supply line 1, and water supply line 1 is connected by reverse osmosis equipment 4 with Xun Huan puddle 3；
Recirculated water filtering pipeline 2 is further included, one end of recirculated water filtering pipeline 2 is connected by water supply pump 5 and Xun Huan puddle 3
It is logical, and the other end of recirculated water filtering pipeline 2 is connected by reverse osmosis equipment 4 with Xun Huan puddle 3；In water supply line 1 and Xun Huan
Moisturizing control valve and Xun Huan water control valve are respectively arranged on water filtration pipeline 2.
It should be noted that reverse osmosis equipment 4 is the characteristic penetrated using the hydrone selection of reverse osmosis membrane, in water
Soluble salt is filtered the device of processing, and in actual production, the water filled by water supply line 1 usually is from water, originally
Water is cheated into recirculated water in 3 after being filtered by reverse osmosis equipment 4.
The operation principle of the circular water treating system for filter both soluble salt that the utility model embodiment provides is：Xun Huan
After the evaporation of water heat, reverse osmosis equipment 4 is opened, is filtered in backward Xun Huan puddle 3 and mended through reverse osmosis equipment 4 by water supply line 1
Enter water, reach the preset water level upper limit until cycling the water level in puddle 3 (this process is " filtering water compensating state ").
When cycling the water level in puddle 3 and reaching the preset water level upper limit, moisturizing control valve is closed, opens simultaneously cycling water control
Valve processed so that the recirculated water of water supply pump 5 from Xun Huan 3 inner extraction of puddle enters recirculated water filtering pipeline 2, and recirculated water further passes through
Recirculated water filtering pipeline 2 enters reverse osmosis equipment 4, and reverse osmosis equipment 4 is filtered the soluble salt in recirculated water, and after filtering
Reverse osmose pure-water flow back to cycle puddle 3, and filter after condensed water (the higher water of saliferous) discharged from reverse osmosis equipment 4 (in figure
It is not shown) (this process is " filtration cycle state ")；
When cycling the arrival preset water level lower limit of the water level in puddle 3, cycle water control valve is closed, opens moisturizing control
Valve, the system is again into filtering water compensating state, to ensure that production line needs the regular supply of water.
Filtration treatment to recirculated water can be realized using the circular water treating system, further reduce the saliferous of recirculated water
Amount, makes the salt content of recirculated water always in undersaturated condition, thus crystal attachment will not be precipitated after by thermal evaporation in recirculated water
In equipment, solve the problems, such as that product appearance scratches and appearance waste product increases, reduces electrochemical corrosion phenomenon.
In above-mentioned circular water treating system, the cooling system on production line need to be cold needed for extraction out of Xun Huan puddle 3
But water, to ensure to produce normal operation, that is to say, that the circulating water flow after the filtering of reverse osmosis equipment 4 returns to Xun Huan puddle 3
Meanwhile the cooling system of production line also needs to extract cooling water from Xun Huan puddle 3 by water supply pump, it is normal raw to ensure
Production, wherein water supply pump are used to provide power to recirculated water.
In order to simplify technique, water supply pump 5 can be set also to be connected with the cooling system of production line, i.e. so that system is filtering
In recurrent state, the water extracted out by water supply pump 5 from Xun Huan puddle 3 is partly into production line cooling system, is cooled down；One
Part thereby simplifies process pipelines into recirculated water filtering pipeline 2, realization filtering, easy to produce.

The water level signal is sent to programmable controller, programmable controller by sensor 7 for monitoring the water level in Xun Huan puddle 3
The numerical signal is judged, and further sends a signal to water supply solenoid valve 11 and circulating electromagnetic valve 21, to control moisturizing
The opening and closing of solenoid valve 11 and circulating electromagnetic valve 21.
When the water level in the Xun Huan puddle 3 that water level sensor 7 detects is higher than water level upper limit value, programmable controller control
Water supply solenoid valve 11 processed is closed, and opens simultaneously circulating electromagnetic valve 21；Water in the Xun Huan puddle 3 that water level sensor 7 detects
When position is less than water level lower limit, programmable controller control water supply solenoid valve 11 is opened, and simultaneously closes off circulating electromagnetic valve 21.Thus
It can be achieved to automatically control the device.
In order to ensure to control the salt content in water relatively low without being precipitated always, long-play reverse osmosis equipment 4 is needed.So
And in fact, the salt in recirculated water to be made not to be precipitated, the salt content in water need to be only controlled in a relatively low scope, allowed
Recirculated water is in undersaturated condition in cooling procedure.
Therefore, for the salt content in further accurate control loop water, unnecessary filtering is avoided, it can be in water supply pump
5 are provided with circulating water quality sensor 6 with the connectivity part of the cooling system of production line；And it circulating water quality sensor 6 and can compile
Range controller is electrically connected.
Specifically, the upper limit for the recirculated water salt content that the salt in recirculated water is made not to be precipitated is set in the programmable controller
Value and lower limiting value, circulating water quality sensor 6 are used to detect the salt content of recirculated water, and the numerical signal of salt content is sent to
Programmable controller, programmable controller judge the numerical signal, and further send a signal to cycling water solenoid valve
21, the opening and closing of control loop water solenoid valve 21, while programmable controller is also used for the unlatching of control reverse osmosis equipment 4
And closing.
In filtration cycle state, when the recirculated water salt content that circulating water quality sensor 6 detects is higher than upper limit value,
Programmable controller control loop water solenoid valve 21 and reverse osmosis equipment 4 are opened, to be filtered to recirculated water；Work as recirculated water
When the recirculated water salt content that water quality sensor 6 detects is less than lower limiting value, programmable controller control loop water solenoid valve 21 is mended
Water solenoid valve 11 and reverse osmosis equipment 4 are turned off (reverse osmosis equipment 4 is in holding state), make recirculated water do not have to filtering directly into
Enter production line, to save energy consumption and water consume excessive processing is avoided to cause the wasting of resources.
When water level sensor 7 again detect cycle puddle 3 in cycle water level reach setting lower limit when, system reopens
Into filtering water compensating state.Thus the automatic energy saving control to the circulation path of the device can be realized.
