[0023] The following further elaborates on this application Figures 1-5 in further detail.

[0024] The embodiment of this application discloses a high-fold concentration treatment device for mine water.

The top of the seventh water delivery pipe 15 is communicated with the sixth water delivery pipe 14; by automatically switching the membrane module concentration sequence through the transmembrane pressure difference, the accumulation of scaling substances at the end of concentration is reduced, ensuring the high concentration ratio of the device while ensuring the stable operation of the device. After secondary concentration, the pressure is increased, and the concentrated water after three times of concentration can be selectively returned to the inlet of the second-stage concentration membrane module, which can effectively reduce the tendency of scaling and pollution in the secondary membrane concentration.

[0025] Reference Figure 1 , Figure 2 and Figure 5 , on the left sides of the tops of the first parallel membrane module 3, the second parallel membrane module 4, and the third parallel membrane module 5, a first connecting pipe 16, a second connecting pipe 17, and a third connecting pipe 18 are respectively communicated.

[0027] Refer to Figure 1 and Figure 3 , anti-slip protrusions are provided at the bottom of the support frame 1, and a reinforcing rod is fixedly connected between the top of the front side and the rear side of the inner cavity of the fixing frame 2; by providing the anti-slip protrusions, an anti-slip effect can be achieved, and by providing the reinforcing rod, the stability of the fixing frame 2 can be improved.

[0028] Refer to Figure 1 and Figure 3 , three support rods are fixedly connected in sequence from top to bottom between the front side and the rear side of the inner cavity of the fixing frame 2, and the surfaces of the first parallel membrane assembly 3, the second parallel membrane assembly 4, and the third parallel membrane assembly 5 are all fixedly connected to the support rods; by providing the support rods, the first parallel membrane assembly 3, the second parallel membrane assembly 4, and the third parallel membrane assembly 5 can be supported, and the stability of the first parallel membrane assembly 3, the second parallel membrane assembly 4, and the third parallel membrane assembly 5 can be improved.

[0029] Working principle: The specific process of treating gasification wastewater is to sequentially open the control valves, namely the first control valve 20, the third control valve 22, the sixth control valve 25, and the eighth control valve 27. Then, sequentially open the high-pressure pump 6 and the booster pump 9. The mine water enters the high-pressure pump 6 through the water inlet pipe 7 for pressurization, and then enters the third parallel membrane module 5 through the first control valve 20 for primary concentration. The concentrated liquid after primary concentration enters the second parallel membrane module 4 through the third control valve 22 for secondary concentration. After the concentrated liquid after secondary concentration enters the booster pump 9 for pressurization, it enters the first parallel membrane module 3 through the sixth control valve 25 for tertiary concentration. The produced water after concentration treatment is collected and recycled. At this time, it is possible to choose to open the seventh control valve 26. The concentrated liquid after tertiary concentration can flow back to the inlet of the second parallel membrane module 4 to increase the flow rate of the secondary concentrated liquid, reduce the risk of fouling and scaling of the membrane module, and extend the operation cycle of the device. When the transmembrane pressure difference before and after the membrane module is greater than the set value, close the high-pressure pump 6 and the booster pump 9, and close the first control valve 20, the third control valve 22, the sixth control valve 25, the seventh control valve 26, and the eighth control valve 27. Sequentially open the control valves, namely the second control valve 21, the seventh control valve 26, the fifth control valve 24, and the fourth control valve 23. Then, sequentially open the high-pressure pump 6 and the booster pump 9. The mine water is pressurized by the high-pressure pump 6 and enters the first parallel membrane module 3 through the second control valve 21 for primary concentration. The concentrated liquid enters the second parallel membrane module 4 through the seventh control valve 26 for secondary concentration. After the concentrated liquid enters the booster pump 9 for pressurization, it enters the third parallel membrane module 5 through the fifth control valve 24 for tertiary concentration. The produced water after concentration treatment is collected and recycled. Subsequently, it is possible to choose to open the third control valve 22. The concentrated liquid after tertiary concentration can flow back to the inlets of multiple second parallel membrane modules 4 to increase the flow rate of the secondary concentrated liquid, reduce the risk of fouling and scaling of the membrane module, and extend the operation cycle of the device.
