All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As shown in fig. 1 to 3, the concentrated water recycling apparatus provided in this embodiment is used for being connected to a reverse osmosis device 100, and includes: a delivery line 200, a check valve 300, and a cooling tower 400; the conveying pipeline 200 is connected with a concentrated water outlet of the reverse osmosis equipment 100, the conveying pipeline 200 is connected with the cooling tower 400, and the conveying pipeline 200 is used for conveying concentrated water generated by the reverse osmosis equipment 100 to the cooling tower 400 for supplementing water; a check valve 300 is located on the delivery line 200, the check valve 300 being used to limit the one-way delivery path of the delivery line 200.
It should be noted that, the cooling tower 400 in the factory refrigeration room uses water as softened water, the concentrated water is produced by reverse osmosis filtration and discharge of the softened water, the source of the concentrated water is the softened water discharged by reverse osmosis filtration, the conductivity of the softened water is 450us/cm, the PH value of the softened water is 7-9, the discharge of the concentrated water is 1866us/cm, the PH values are 6.5-8.5, and the total nitrogen is 1.855mg/L, so the concentrated water can meet the requirement of the cooling tower 400; specifically, the reverse osmosis device 100 sequentially conveys softened water to a reverse osmosis membrane position through sand filtration, carbon filtration, sugar filtration and a booster pump, purified water and concentrated water are manufactured through the reverse osmosis membrane, the concentrated water can be conveyed to the cooling tower 400 through the conveying pipeline 200, the concentrated water is sprayed into the cooling tower 400, and water used by the cooling tower 400 is ensured, wherein the power of the conveying pipeline 200 is the booster pump of the reverse osmosis device 100; further, in order to avoid the back flow of the concentrated water, by installing the check valve 300 at one end of the delivery pipe 200 near the reverse osmosis membrane, the check valve 300 can limit the one-way delivery of the concentrated water delivered by the delivery pipe 200 to the cooling tower 400 along the reverse osmosis apparatus 100, thereby preventing the reverse flow of the concentrated water from polluting the reverse osmosis membrane system after the reverse osmosis apparatus 100 stops making water.
In the preferred embodiment of the present utility model, overflow pipe 900 is also included; the cooling tower 400 is provided with an overflow port 401, the overflow port 401 being located at a basin of the cooling tower 400, the overflow port 401 being in communication with the overflow pipe 900.

It should be noted that, because the PH value of the softened water is alkaline at 7-9, a large amount of alkali salt is precipitated and attached to the filler of the cooling tower 400 along with evaporation of the water, and untimely pollution discharge and cleaning can affect the heat exchange efficiency and production failure of the cooling tower 400; in this embodiment, since the concentrated water is always conveyed to the cooling tower 400 for water replenishment, when the water level of the cooling tower 400 is high, the concentrated water is directly discharged through the overflow port 401, so that the concentration of the alkaline water raised by evaporation of the cooling tower 400 is reduced, the scaling condition of the cooling tower 400 is relieved, the heat exchange efficiency is increased, and the risk of blocking the filter due to the alkaline salt is reduced; in the actual use process, the overflow process is actually equivalent to the pollution discharge process of the cooling tower 400, the fresh water is continuously replaced, and the packing scale of the cooling tower 400 is obviously reduced; because the water consumption is large during production, the water temperature for water treatment is low, the temperature of the fan of the cooling tower 400 is about 17 ℃, and the temperature of the fan of the cooling tower 400 is 20 ℃, when the concentrated water is discharged to overflow the cooling tower 400, the water temperature of a refrigeration cycle system can be reduced, and the water supplementing consumption of softened water to the cooling tower 400 can be reduced, so that the energy-saving effect is achieved.
According to the actual operation process, the cooling tower 400 is compared before and after the concentrated water is utilized, the concentrated water is used for replacing the softened water to be used as cooling water of the cooling tower 400, scaling is reduced, specifically, the water supplementing amount of the cooling tower 400 is 40-80 tons per day, the water supplementing amount is the evaporation amount of the cooling water in a basin of the cooling tower 400, when alkali salt is precipitated and crystallized on the surface of a filler in the process of evaporation of the softened water, the conductivity of the softened water in the cooling tower 400 is 3000us/cm, the conductivity is higher than the conductivity of the actual concentrated water, the concentrated water is continuously injected into the cooling tower 400 and is discharged through an overflow port 401 all the time, the conductivity is continuously lower than 2000us/cm, and the scaling phenomenon of the basin and the filler of the cooling tower 400 can be obviously relieved from the actual use condition.
Alternatively, the overflow pipe 900 may employ a rain drain network.
