Detailed Description
In order to clearly illustrate the technical characteristics of the scheme, the scheme is explained below through a specific embodiment.
Referring to fig. 1, the present utility model is: the utility model provides a multi-functional processing apparatus of oil field reinjection water, wherein, including the pipeline 3 that is used for transmitting reinjection water 2, along the flow direction of reinjection water 2, the anticorrosive jar 1, the sterilization jar 9 and the deoiling jar 12 of intercommunication setting on pipeline 3 in proper order, the first low frequency electromagnetic wave generator 4 of reinjection water 2 in acting on anticorrosive jar 1, and the second low frequency electromagnetic wave generator 5 of reinjection water 2 in acting on sterilization jar 9.
Before the anti-corrosion tank 1 and the sterilization tank 9 are respectively arranged on the existing oil removal tank 12, the production stopping and tank cleaning of the oil removal tank 12 are not needed, the construction period and the transformation cost are reduced, and only the anti-corrosion tank 1 and the sterilization tank 9 are respectively constructed and then are arranged on the pipeline 3 in front of the oil removal tank 12; the low-frequency electromagnetic wave generator is the prior art and will not be described here again.
The low-frequency electromagnetic wave generated by the low-frequency electromagnetic wave generator is transmitted back and forth between the emitter electrode and the receiving electrode to form an electric field and a magnetic field with specific frequency, and the electron cloud of water molecules, bonds, ions or any substances in the water is influenced by the electric field and the magnetic field, so that the H-O-H dipole moment in the water molecules is instantaneously increased or reduced, hydrogen bonds with adjacent water molecules can be pulled up or elongated or broken, the symmetry of O-H bonds can be more symmetrical or more asymmetrical vibration, so that the entropy energy of water molecules and water clusters is increased, and the heat energy required by some reactions is reduced, such as direct reaction of iron into ferroferric oxide, crystallization of calcium carbonate in the water without forming calcium scale on the hot surface, deformation of the hydrogen bonds connecting a DNA double-helix structure and incapacity of opening, and the reactions which cannot occur under natural conditions can occur. This energy release process can effectively solve the problems of water scaling and corrosion while inhibiting the growth of microorganisms.
Preservative mechanism: the continuous release of energy from the high energy water molecules to the iron surface also forms a layer of high energy electric resistance on the iron surface during the release of energy, which can prevent or reduce the flow of corrosion current and thus reduce the corrosion rate. When corrosion occurs, red embroidery is not formed in the high-energy continuous iron-impact corrosion, but a black magnet layer, namely Fe 3 O 4 。Fe 3 O 4 Is an oxide layer with stable structure, high conductivity, compactness and optimal corrosion resistance. When Fe is 3 O 4 After the conductive protective layer is formed on the surface of the iron, when current flows into the electrolyte through the iron and the magnet layer, the current can only flow into the electrolyte through the magnet layer because the lower iron layer is only contacted with the magnet layer, but the magnet layer cannot be dissociated, so that the effect of effective corrosion resistance is achieved.
In addition, when the iron molecules are no longer dissociated and lost, the conditions required for the metabolic reactions of the SRB bacteria or iron bacteria are essentially broken down, resulting in the death of the bacteria without the availability of viable energy.
Sterilization mechanism: bacterial survival is the conversion of electron flow into survival energy. When the bacteria are subjected to the electric field and the magnetic field of the low-frequency electromagnetic waves, the electron flow of the bacteria is influenced by the low-frequency electromagnetic waves and cannot flow, so that the bacteria lose survival energy and splitting capacity and only stretch. All of these help control the growth of the bacteria and their metabolic processes.
When in use, the reinjection water 2 is subjected to corrosion prevention treatment through the corrosion prevention tank 1, the reinjection water is excited to charge energy, and then the energy is released from the pipeline and the tank surface contacted with the high-energy water, so that the corrosion of the pipe and the tank body is controlled or a black magnet layer Fe is directly formed on the surface 3 O 4 The corrosion of the reinjection water 2 to the working environment of the subsequent process can be avoided or reduced, the service life of the device is prolonged, the maintenance cost of the device is reduced, the microbial growth is inhibited, the sterilization workload in the subsequent process is reduced, the sterilization efficiency is improved, and the device is subjected to the corrosion prevention treatmentThe post reinjection water 2 is subjected to further sterilization treatment through the sterilization tank 9, the propagation of bacteria in the water is controlled to achieve the fungus control effect, and then the bacteria enter the oil removal tank 12 for removing oil, so that the oil removal efficiency of the oil removal tank can be greatly improved, and the treatment effect of the reinjection water 2 is ensured.
