Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, and particularly relates to a high-efficiency treatment device for high-salt organic wastewater. Background Technique

[0002] The water quality characteristics of industrial saline wastewater such as oil refining, petrochemical, coal chemical, and flue gas desulfurization are characterized by high salt content, high hardness, high fluoride, high silicon, high heavy metals, etc., and the treatment is difficult.

[0003] In the prior art, the reverse osmosis membrane technology is used to treat high-salt organic wastewater. The reverse osmosis (RO) membrane technology utilizes the principle of a semi-permeable membrane to separate the water and dissolved salts in the wastewater. By applying pressure to push the water through the membrane, relatively pure water is obtained, and the remaining concentrated brine is discharged or further treated for resource utilization. The reverse osmosis method can effectively remove most of the dissolved salts in high-salt water, and has simple operation and strong adaptability. However, during the treatment of wastewater, the RO membrane will become saturated after treating a certain amount of wastewater. In the prior art, the RO membrane is cleaned by backwashing. However, the existing backwashing device uses a water pump to clean the RO membrane, and there is a problem of insufficient pressure during the startup of the water pump. To ensure the cleaning effect, it is necessary to extend the backwashing time to increase the pressure, and the long backwashing time will affect the treatment efficiency of the device for wastewater.

[0004] Therefore, it is very necessary to invent a high-efficiency treatment device for high-salt organic wastewater to solve the above problems. Content of the Utility Model

[0014] 1. By setting the treatment pipe, RO filter element, connecting pipe, sewage discharge pipe, drain pipe and transition pipe, the treatment pipe and the RO filter element can realize the treatment of organic wastewater. When the RO filter element needs to be backflushed and cleaned after being used for a certain period of time, the activity plug inside the transition pipe moves upward, so that the filtered clear water inside the transition pipe is squeezed into the treatment pipe.

After the movable plug moves upward for a certain distance, the push rod jacks up the stop block. At this time, the blockage of the sewage pipe by the stop block is released. At this time, the pressurized clear water can backwash the RO filter element and discharge the sewage. The design of the movable plug and the stop block increases the pressure when backwashing the RO filter element inside the treatment pipe, so as to improve the backwashing effect of the device.

When the device is normally treating sewage, the activity plug 14 is located at the bottom end of the transition pipe 12 and below the drain port 13. At this time, the filtered clear water can be discharged through the drain port 13. During the backwashing process of the device, the activity plug 14 moves above the drain port 13. At this time, the clear water in the transition pipe 12 cannot be discharged through the drain port 13;

[0025] A partition plate 17 is fixedly provided in the middle of the inner side of the transition pipe 12. The stop block 15 is located above the partition plate 17, and a spring is provided between the stop block 15 and the top end of the inner side wall of the transition pipe 12. The spring is used to press the stop block 15 tightly above the partition plate 17. At this time, the stop block 15 blocks the sewage discharge pipe 10 and the sewage discharge port 16. A plurality of ejector rods 18 are provided around the upper surface of the activity plug 14. A plurality of jacks adapted to the ejector rods 18 penetrate through the middle of the partition plate 17. An electric telescopic rod 19 is fixedly provided at the top end of the transition pipe 12. The bottom end of the electric telescopic rod 19 is slidably provided in the middle of the partition plate 17, and the bottom end of the electric telescopic rod 19 is connected to the top end of the activity plug 14. The electric telescopic rod 19 is used to drive the activity plug 14 to move up and down;

[0026] One end of the sewage discharge port 16 is fixedly provided with a sewage pump 20. The sewage pump 20 is used to assist in discharging the wastewater and impurities inside the RO filter element 6. The sewage pump 20 is started after the backwashing process ends. It can discharge the impurities and sewage in the RO filter element 6 that cannot be discharged due to insufficient pressure;

[0027] Both ends of the treatment pipe 2 are fixedly provided with fixed covers 3. Inside the fixed cover 3, a positioning cover 21 is detachably provided by means of threads. In the middle of the inner side of the positioning cover 21, a solenoid valve 22 is fixedly provided. One end of the solenoid valve 22 corresponds to the middle of the RO filter element 6, and a connecting flange 23 is fixedly provided at the other end of the solenoid valve 22. The connecting flange 23 is used to connect the device to the sewage pipeline, and the solenoid valve 22 is used to control the entry of sewage into the device;

[0028] It should be noted that in this embodiment, sealing rings are provided on the outer sides of both ends of the RO filter element 6, the movable plug 14, and the stopper 15 to ensure the sealing effect of the device. The model of the sealing ring adopts the models sold on the market and is not limited without affecting the implementation of this embodiment.

[0029] The working principle of the present utility model:

[0030] When this device is in use, the treatment pipe 2 is connected to the sewage pipeline through the connecting flanges 23 at both ends. The sewage to be treated enters the inside of the RO filter element 6 through the connecting flange 23 and the solenoid valve 22, and under the action of pressure, passes through the RO filter element 6 and enters the inside of the treatment pipe 2. At this time, salts, impurities, etc. in the sewage are filtered by the RO filter element 6, and the clear water enters the treatment pipe 2. The clear water enters the transition pipe 12 through the drain pipe 11 and then is discharged through the drain port 13. In this process, the treatment of sewage can be realized;

[0031] After the device runs for one cycle, the RO filter element 6 needs to be backflushed and cleaned. At this time, the two solenoid valves 22 are closed, the sewage stops entering the device, and the electric telescopic rod 19 is controlled to move upward. The electric telescopic rod 19 drives the movable plug 14 to move upward. The movable plug 14 moves above the drain port 13. At this time, the clear water in the transition pipe 12 cannot be discharged through the drain port 13. The movable plug 14 continues to move upward, and the clear water in the transition pipe 12 is squeezed by the movable plug 14 and flows back into the treatment pipe 2. At this time, the pressure of the clear water in the treatment pipe 2 rises;

[0032] The movable plug 14 continues to move upward until the ejector rod 18 is inserted into the jack in the partition plate 17. At this time, the ejector rod 18 pushes the stopper 15 upward, causing the stopper 15 to be misaligned with the sewage discharge pipe 10 and the sewage discharge port 16. At this time, the sewage inside the RO filter element 6 and the connecting pipe 9 can be discharged through the sewage discharge pipe 10 and the sewage discharge port 16. Moreover, as the movable plug 14 moves upward, the pressurized clear water inside the treatment pipe 2 can backflush the RO filter element 6, and the salts and impurities inside the RO filter element 6 are flushed down. The salts and impurities are discharged through the sewage discharge pipe 10 and the sewage discharge port 16 to realize the backflush of the RO filter element 6;

[0033] During the process of backwashing and cleaning the RO filter element 6, the transition pipe 12, the drain pipe 11 and the treatment pipe 2 form a pipeline for backwashing and cleaning. The clear water filtered by the RO filter element 6 is guided by the backwashing pipeline and flushes the RO filter element 6 from the outside to the inside, so that the particulate impurities blocked inside the RO filter element 6 are washed into the RO filter element 6 and then discharged. The flushing method from the outside to the inside can better flush out the particulate matter inside the RO filter element 6 to improve the flushing effect of the RO filter element 6.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
