Abstract
The utility model discloses an automatic control loop system for improving the efficiency of reverse osmosis unit, including an original water tank, an original water pump, a mechanical filter, an activated carbon filter, a softener, a first intermediate water tank, a reverse osmosis unit and a second intermediate water tank connected in sequence, wherein a water turbidity meter is provided between the softener and the first intermediate water tank, two pipelines are branched from the water turbidity meter, one is connected to the first intermediate water tank, and a first valve is provided on the pipeline; the other is connected to the original water tank, and a second valve is provided on the second pipeline. The utility model ahs advantage that the water produced after preliminary treatment is returned to the original water tank for re-filtering, if the water is not conform to standard. The turbidity of water in the original water tank itself is reduced to reduce the turbidity of water produced after preliminary treatment through re-filtering. The design not only reduces the turbidity of produced water, but also improves the water-use efficiency, and saves the cost.
Description
Technical field
The utility model relates to a kind of automatic control loop system that improves reverse osmosis unit efficient.
Background technology
Reverse osmosis is a new membrane separation technique that grows up in the sixties, is to rely on reverse osmosis membrane to make solvent and solute in the solution carry out separating process under pressure.The reverse osmosis desalination principle is exactly in water salty, imposes the pressure bigger than naturally osmotic pressure, and infiltration is carried out round about, and the water molecules in the former water is pressed onto the other side of film, becomes clean water, thus reach remove anhydrate in the purpose of salinity.At present, utilize reverse osmosis method to produce pure water technology, with its environmental protection, stable effluent quality, less energy intensive, the strong characteristics of giving prominence to that wait of adaptive faculty have obtained using widely in beverage, chemical industry, electric power, electron trade.
For the turbidity of water inlet, going out electrical conductivity of water all has very strict requirement in reverse osmosis unit.The quality of former water pretreatment directly influences the techno-economic effect and the long-term safety operation of reverse osmosis, it is a very important ring during industrial water supply is handled, washed ore strainer, activated charcoal filter and accurate filter are adopted in the water pretreatment of present most of technological processs Central Plains.But it is more to contain pollutent at Yuan Shui, and when water quality was relatively poor, past contact was difficult to reach the specification of quality of pretreated water, causes reverse osmosis membrane very easily to be polluted, thereby shortened the work-ing life of reverse osmosis membrane, and water water quality is produced in influence.And going out aspect the electrical conductivity of water, general reverse osmosis membrane can reach 97% ratio of desalinization, but some the time we need higher ratio of desalinization.
The utility model content
The purpose of this utility model is to provide a kind of automatic control loop system that improves reverse osmosis unit efficient, can effectively solving prior art Central Plains water, to contain pollutent more, when water quality is relatively poor, the specification of quality that is difficult to reach pretreated water toward contact, cause reverse osmosis membrane very easily to be polluted, thereby shorten the work-ing life of reverse osmosis membrane, the problem of water water quality is produced in influence.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of automatic control loop system that improves reverse osmosis unit efficient, comprise the raw water box, raw water pump, mechanical filter, activated charcoal filter, softening agent, first intermediate water tank, reverse osmosis unit, second intermediate water tank that connect successively, be provided with the water turbidity survey meter between the described softening agent and first intermediate water tank, tell two pipelines from the water turbidity survey meter, article one, link to each other with first intermediate water tank, pipeline is provided with first valve; Another links to each other with raw water box, and pipeline is provided with second valve.
Preferably, be provided with conductance instrument between the described reverse osmosis unit and second intermediate water tank, tell two pipelines from conductance instrument, one links to each other with first intermediate water tank, and pipeline is provided with the 3rd valve; Another links to each other with second water tank, and pipeline is provided with the 4th valve; When first-stage reverse osmosis product water is non-compliant water is back to raw water box desalination again.Thereby the specific conductivity that has reduced water itself in the raw water box has reduced first-stage reverse osmosis through desalination once more produces electrical conductivity of water.This design has not only reduced product water demineralizing rate, and has improved the utilization ratio of water, has saved cost.This technology can apply on the partial reverse osmosis unit equally.
Preferably, described first valve, second valve, the 3rd valve, the 4th valve are electrovalve; Can opening and closing according to the measurement autocontrol valve of water turbidity survey meter and conductance instrument.
Compared with prior art, the utility model has the advantages that: when pretreated product water is non-compliant, water is back to raw water box and filters again.Thereby the turbidity that reduced water itself in the raw water box has reduced the turbidity that water is produced in pre-treatment through filtering once more.This design has not only reduced produces the turbidity of water, and has improved the utilization ratio of water, has saved cost.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Consulting Fig. 1 is a kind of embodiment that improves the automatic control loop system of reverse osmosis unit efficient of the utility model, a kind of automatic control loop system that improves reverse osmosis unit efficient, comprise the raw water box 1 that connects successively, raw water pump 2, mechanical filter 3, activated charcoal filter 4, softening agent 5, first intermediate water tank 9, reverse osmosis unit 10, second intermediate water tank 11, be provided with water turbidity survey meter 6 between the described softening agent 5 and first intermediate water tank 9, tell two pipelines from water turbidity survey meter 6, article one, link to each other with first intermediate water tank 9, pipeline is provided with first valve 8; Another links to each other with raw water box 1, and pipeline is provided with second valve 7.Be provided with conductance instrument 12 between the described reverse osmosis unit 10 and second intermediate water tank 11, tell two pipelines from conductance instrument 12, one links to each other with first intermediate water tank 9, and pipeline is provided with the 3rd valve 13; Another links to each other with second water tank, and pipeline is provided with the 4th valve 14.Described first valve 8, second valve 7, the 3rd valve 13, the 4th valve 14 are electrovalve.
A pre-treatment is set on water turbidity survey meter 6 produces the threshold value of water turbidity, state 1: when turbidity was lower than the value that we set, system normally moved, and first valve 8 is opened, second valve 7 is closed, and water enters the reverse osmosis unit 10 that first intermediate water tank 9 is supplied with the back by pipeline.State 2: when delivery turbidity is higher than the value of our setting, delivery turbidity can not satisfy the water inlet requirement of reverse osmosis unit 10, water turbidity survey meter 6 can send the guard signal of one+24V and give PLC, PLC controlled first valve 8 and closed this time, second valve 7 is opened, and allows water flow back to raw water box 1 by pipeline and filters again.When being lower than set(ting)value, turbidity comes back to state 1.
