Description

Technical Field

[0001] The utility model relates to a reverse osmosis device, in particular to a reverse osmosis device for oil production sewage, belonging to the technical field of oil production. Background Art

[0002] Reverse osmosis technology is one of the most advanced and energy-saving effective separation technologies today. It uses a sufficiently large pressure to separate the solvent in the solution through a reverse osmosis membrane. Because it is opposite to the natural osmosis direction, it is called reverse osmosis. The reverse osmosis water treatment process uses the reverse osmosis membrane to selectively pass the solvent through and intercept ionic substances. The static pressure difference on both sides of the membrane is used as the driving force to overcome the osmotic pressure of the solvent, so that the solvent passes through the reverse osmosis membrane to achieve a membrane process for separating the liquid mixture. Reverse osmosis equipment is often required in the process of oil production.

[0003] According to the patent number CN210286956U, a reverse osmosis device for petrochemical wastewater is disclosed, including support legs, and the upper surface of the support legs is fixedly connected to a table. The surface of the table is fixedly connected to a treatment barrel, one end of the water inlet pipe is fixedly connected to a sewage barrel, and both sides of the sewage barrel are fixedly connected to one end of a support frame. A sewage treatment device is arranged inside the treatment barrel, and the sewage treatment device includes a support plate, and the inner wall of the treatment barrel is fixedly connected to both sides of the support plate.

[0004] The above scheme can facilitate the replacement and cleaning of the reverse osmosis membrane body during implementation. However, it is difficult to clean the impurities and pigments filtered out by the filter during implementation. More impurities and pigments accumulate on the surface of the filter and easily cause blockage, affecting the filtration efficiency of the sewage. For this reason, we provide a reverse osmosis equipment for petroleum production sewage to solve the above problem. Utility Model Content
