Abstract
Description
TECHNICAL FIELD
[0001] The utility model discloses an emulsion breaking device belongs to emulsion breaking equipment technical field, and specifically relates to an ultrasonic emulsion breaking device. BACKGROUND
[0002] The emulsified oil existing in the liquid forms the hydrophilic protective film of directional arrangement and double electric layer structure on the surface of oil particle. The same charge of the protective film repels each other, so that the oil particle cannot contact and collide and become large, forming stable oil-in-water turbid emulsion, which can only be separated by floating after emulsion breaking. Emulsion breaking is to destroy the protective film around the oil particle, so that oil and water are separated.
[0003] There are mainly two kinds of emulsion breaking mechanisms: one is to compress the double electric layer of emulsion particles or neutralize the surface charge, so that the particles change from repulsion state to contact and collision and aggregation state; the other is to break the interface of emulsifier or replace it with another surface active substance that cannot form a firm interface film, so that the oil particles are released and aggregated.

In addition, the technical features involved in the different embodiments of the utility model described below can be combined with each other as long as they do not conflict with each other.
[0016] An ultrasonic demulsification device, comprising: adjusting pool 01, lifting pump 02, demulsification device 03, ultrasonic device 06, gas source 04, gas distribution bag 05, oil groove 07.
[0017] In one embodiment, such as Figure 1 As shown, the booster pump 02 is installed in the regulating tank 01 and the outlet of the booster pump 02 is connected to the inlet of the demulsifying device 03. The ultrasonic device 06 is located in the demulsifying device 03. The input end of the air distribution manifold 05 is connected to the air source 04 and the output end is connected to the ultrasonic device 06. The oil tank 07 is connected to the oil outlet of the demulsifying device 03.
[0018] In one embodiment, such as Figure 1 As shown, the demulsification device 03 is divided into a separation zone and an ultrasonic demulsification zone. The ultrasonic device 06 is located in the ultrasonic demulsification zone. The demulsification device 03 is equipped with a multi-point water outlet and an oil discharge tank 07. The multi-point water outlet outputs liquid to the next-level unit. The oil discharge tank 07 is located at the top of the demulsification device 03 and is connected to the oil tank 07, outputting oil into the oil tank 07.
[0019] In one embodiment, such as Figure 1 As shown, both the regulating tank 01 and the demulsifying device 03 are equipped with level gauges.
[0020] In one embodiment, such as Figure 1 As shown, the ultrasonic demulsification device, combined with an ultrasonic generator, features a cleverly designed process including a demulsification zone and a separation zone. Utilizing sound waves with frequencies higher than 20kHz, when ultrasonic waves of a certain intensity pass through the medium, a series of physical and chemical effects are generated. Because the wavelength of ultrasound in liquids is 10–0.015 cm, much larger than the size of molecules, and closely related to the collapse of cavitation bubbles generated in the liquid, its driving force is acoustic cavitation. When sufficiently strong ultrasonic waves pass through the liquid, when the sound pressure amplitude of the negative pressure half-cycle exceeds the static pressure inside the liquid, the tiny bubbles (cavitation nuclei) existing in the liquid rapidly increase in size. In the subsequent positive pressure phase of the sound waves, the bubbles undergo adiabatic compression and collapse, generating an extremely brief, strong pressure pulse at the moment of collapse. A local hot spot forms in the tiny space around the bubble, with a temperature reaching 5000K and a pressure reaching 500 atm. After lasting for several microseconds, this hot spot cools down at a rate of 109 kJ / s, accompanied by a powerful shock wave and a jet with a speed of 400 km / h. When ultrasound passes through a fluid medium containing tiny oil droplets, the oil droplets begin to vibrate along with the medium. However, because particles of different sizes have different vibration velocities, the oil droplets collide and adhere to each other, increasing in both volume and weight. Then, as the particles grow larger, they can no longer vibrate with the ultrasound and can only move randomly, continuing to collide, adhere, and grow larger until they finally float to the surface, forming a suspended oil that achieves a demulsification effect.
[0021] The process of this utility model is as follows:
[0022] Raw solution→adjustment pool→ultrasonic demulsification device→supply gas to ultrasonic generator (inside ultrasonic demulsification device)→water outlet of multi-point water outlet device→to next unit;
[0023] →liquid to separation zone (inside ultrasonic demulsification device);
[0024] →floating oil to oil discharge groove→oil groove.
[0025] Working principle: raw solution enters adjustment pool 01, enters demulsification device 03 through lifting pump 02, demulsification device 03 is divided into ultrasonic demulsification zone 03-1, separation zone 03-2, oil discharge groove 03-3, multi-point water outlet device 03-4, gas source 04 to gas distribution bag 05 to ultrasonic generator 06, raw solution first advances to ultrasonic demulsification zone 03-1 to separation zone 03-2 through multi-point water outlet device 03-4, oil to oil discharge groove 03-3 to oil groove 07.
[0026] Obviously, the above embodiments are only examples for clearly illustrating, but not limit the embodiments. For ordinary skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, all the embodiments need not and can not be exhausted. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
