Description
Technical Field
The invention belongs to the technical field of oil removal, and particularly relates to an integrated ultrasonic emulsion removing device.
Background
⑴ suspension oil, ⑵ dispersion oil, ⑶ emulsified oil and ⑷ dissolved oil.
⑴ the suspended oil beads have particle size of more than 100 μm, and are easy to float on the liquid surface to form oil film or oil layer (processing method: can be scraped off by a surface oil scraper directly);
⑵ the diameter of the dispersed oil beads is generally 10-100 μm, and tiny oil beads are suspended in the solution, are unstable, and often form floating oil after standing for a certain time;
⑶ the particle size of emulsified oil globule is less than 10 μm, generally 0.1-0.2 μm, and the oil globule is often stable emulsion due to the surfactant contained in the solution (treatment method: demulsification is first carried out to convert into floating oil and then scraped by a surface oil scraper);
⑷ the beads of dissolved oil are smaller than the beads of emulsified oil, some can be as small as a few nm, and are oil particles dissolved in solution.
The emulsified oil present in the oil-containing solution forms a hydrophilic protective film having an electric double layer structure and oriented arrangement on the surface of the oil particles. The charges with the same sign on the protective film are mutually repelled, so that the oil particles cannot be contacted and collided and are large, and a stable oil-in-water turbid emulsion is formed. Some of the emulsified oils in the solution are emulsions prepared to meet the needs of a certain process, and some of the emulsified oils are naturally formed by oil particles in water adsorbing a surfactant or fine solid particles under agitation of a water flow. The former has strong hydrophilicity due to full emulsification, and can float upwards and separate only after demulsification; the latter can be removed by air-float method because of insufficient emulsification, weak hydrophobicity or weak hydrophilicity, and the small amount can be separated after demulsification. Demulsification is the breaking of the protective film around the oil particles to separate the oil from the water. The demulsification mechanism mainly comprises two mechanisms: one is that the double electric layer of the emulsion particle is compressed or the surface charge is neutralized, so that the particle is converted from a repulsive state to a coalescence state capable of contact collision; the other is to rupture or displace the emulsifier interfacial film with another surfactant that does not form a strong interfacial film, allowing the oil particles to be released and coalesced. In the prior art, the oil removal efficiency is low, and some chemical agents are usually added for demulsification and then oil removal.

Micro bubbles in the dissolved air water generated by the dissolved air tank are bonded with micro suspended particles in the water, so that the suspended oil floats to the water surface along with bubbling to form floating oil, and the aim of removing the oil is fulfilled.

The invention adopts the processing scheme of breaking emulsion by ultrasonic waves to form floating oil and scraping the floating oil by a scraper to remove the emulsified oil, wherein the ultrasonic waves refer to sound waves with the frequency higher than 20kHz, and when the ultrasonic waves with certain intensity pass through a medium, a series of physical and chemical effects can be generated. Because the wavelength of the ultrasonic wave in the liquid is 10-0.015 cm (equivalent to 15 kHz-10 MHz), the ultrasonic wave is far larger than the size of a molecule, and the ultrasonic wave has close relation with collapse (collapse) of cavitation bubbles generated in the liquid, and the power source of the ultrasonic wave is acoustic cavitation (sound cavitation). When ultrasonic waves with enough strength pass through liquid, when the sound pressure amplitude of a sound wave negative pressure half period exceeds the internal static pressure of the liquid, tiny bubbles (cavitation nuclei) in the liquid are rapidly increased, the bubbles are adiabatically compressed and burst out in a successive sound wave positive pressure phase, a very short strong pressure pulse is generated at the burst out moment, a local hot spot (hot spot) is formed in a tiny space around the bubbles, the temperature of the local hot spot is 5000K, the pressure of the local hot spot reaches 500atm, the local hot spot is cooled along with the local hot spot after the continuous several microseconds, the cooling rate reaches 109K/s, and strong shock waves (for homogeneous liquid media) and jet flows (for heterogeneous liquid media) with the speed of 400km per hour are accompanied. When ultrasonic waves pass through a fluid medium with tiny oil particles, the oil particles in the ultrasonic waves begin to vibrate together with the medium, but because the particles with different sizes have different vibration speeds, the oil particles collide and adhere to each other, and the volume and the weight are increased. Then, the particles can not be vibrated along with the ultrasonic vibration because the particles are enlarged, and only can do random movement, and the particles continue to collide, adhere and enlarge and finally float upwards to form floating oil.
