Description

Technical Field

[0001] The utility model discloses an air deoiling device, belongs to the technical field of RO coating machines, and specifically relates to an RO coating machine oven exhaust deoiling device. Background Art

[0002] RO coating machine refers to the coating equipment used in reverse osmosis (RO) system. RO coating machine is mainly used in water treatment industry, which processes tap water, seawater or other sewage through filtration and membrane separation technology to remove ions, dissolved substances, bacteria and viruses, so as to obtain pure water.

[0003] The core part of the RO coating machine is the semi-permeable membrane, which has a microporous structure and can filter out most of the solutes, particles and microorganisms in the water, allowing only water molecules to pass through, thereby achieving the purpose of water purification and impurity removal. The RO coating machine usually includes the following main components

[0004] Pretreatment system: filter, dechlorinate and soften the raw water to reduce the pollution to the RO membrane and extend the life of the RO membrane.

[0005] High-pressure pump: provides enough pressure to push water into the RO membrane, allowing water molecules to reverse osmosis through the RO membrane, while solutes, particles and microorganisms are retained outside the membrane to form a concentrate.

[0006] RO membrane assembly: includes multiple RO membrane elements, each element is stacked with multiple layers of RO membrane sheets. The selection and configuration of RO membranes vary depending on the water source.

[0007] Control system: monitor and control the operating parameters of the RO coating machine, such as pressure, flow, concentrate discharge, etc., and adjust the operating conditions as needed.

[0008] Concentrate treatment system: The concentrate in the RO membrane is usually treated by backwashing, discharge or recycling.

[0009] The working principle of the RO coating machine is to push the raw water into the RO membrane through the pressure generated by the high-pressure pump. The water molecules pass through the RO membrane, while the solutes, particles and microorganisms are retained outside the membrane to form a concentrated liquid, thereby achieving the effect of water purification and impurity removal.
