Description
Technical field the present invention relates to a kind of ultrasonic wave air supporting machine, can be widely used in sewage and gives in the water treatment.
The oil in water emulsion that exists in the background technology sewage; particle diameter is little, and elaioleucite surface forms the hydrophilic protective films that aligns and have double electrical layers, protective membrane with homocharge mutually exclusive; elaioleucite can not be increased with merging by contact-impact, form the muddy milk sap of stable oil-in-water-type.Existing air supporting machine can not effectively be removed the oil that is attached on the particulate matter, can not solve the colourity problem of industry waste water such as printing and dyeing, and low for the waste water COD clearance of the chemical industry of biochemical difference.
Summary of the invention the object of the present invention is to provide a kind of simple in structure, use is easy to operate, pollution-free, energy consumption is low, oil removal efficiency is high, remove colourity, improve the high ultrasonic wave air supporting machine of biochemical, waste water COD clearance height, organic rate of recovery height, molten gas efficient of waste water.
In order to achieve the above object, ultrasonic wave air supporting machine of the present invention, comprise tank body, be installed in the dissolving on tank body left end top, the air dissolved pump that is installed in tank body left end bottom and links to each other by the Gas dissolving pipe road with dissolving, be installed in the ultrasonic generator in the tank body ultrasonic response district, be installed in the whipping appts in the tank body coagulation district, be installed in the vent valves that tank body air flotation zone bottom is used to discharge the solid sediment, be installed in the chain type slag scraper in the tank body air flotation zone, be installed in the gravity flow deslagging funnel device on the tank body exhalant region; Said tank body from left to right, sets gradually the ultrasonic response district, coagulation district, air flotation zone, exhalant region.
Ultrasonic wave air supporting machine of the present invention, its principle of work is: ultrasonic wave and air supporting are combined, realize the sewage breakdown of emulsion and separate, reach the purpose of breaking milk and removing oil.When ultrasonic wave when the fluid medium of oil or fat particles is arranged, elaioleucite wherein begins to vibrate with medium, but because the particle that varies in size has different vibration velocities, elaioleucite will run foul of each other, bonding, volume and weight all increases, then, because particle becomes and can not can only do random motion with ultrasonic vibration greatly, continue collision, bonding, become big, come-up forms oil slick at last.Oily soln behind ultrasonic dehydration enters air flotation zone, in water, produce the trickle bubble of sufficient amount, the suspension oil particle adheres to mutually in trickle bubble and the water, forms global density " bubble-particle " complex body less than water, makes suspended particles float to the water surface with bubble.
Ultrasonic wave mainly comes from its sound cavitation effect to the Degradation of organic pollution aquifer.Acoustic cavitation is an extremely complicated physical phenomenon, and it is meant that the small complex in the liquid is activated, and shows as a series of dynamic processes such as vibration, growth, contraction and even collapse of complex under acoustic wave action.This process is to concentrate the sound field energy, and the adiabatic process that discharges rapidly.The cavitation of utilizing on the sonochemistry mostly is transient cavitation, promptly under bigger sound intensity effect, occurs in the cavitation in the sound wave cycle, this moment the sound wave negative pressure mutually in, cavitation bubble enlarges rapidly, under the sound wave malleation acts on mutually, is compressed to collapse rapidly thereupon, during the cavitation bubble collapse, form hot localised points, its temperature can reach more than the 5000K, and pressure reaches 50MPa, continue after the number microsecond, focus cools off thereupon.For the homogeneous liquid medium, powerful shockwave is arranged; For heterogeneous medium, speed per hour is up to the jet of 400km.Under these extreme conditions, free radical reaction takes place in the organism in the sewage in cavitation nucleus, chemical bond rupture or Pintsch process reaction etc., thus make the difficult degradation macromolecule organic be converted into micromolecular organism or corresponding inorganics.Usually be easy to the evaporable organism pyrolytic reaction mainly takes place, the reaction of extremely similar combustion chemistry makes its thorough degraded, should not or difficult evaporable organism free radical reaction mainly takes place.The High Temperature High Pressure that the moment of cavitation bubble collapse produces during the acoustic cavitation reaction makes H
2O is decomposed into free radical, and the part free radical can be combined into H again
2O
2In the reaction of free radical, can produce free radical, when oxidize contaminants, can cause chain reaction, be carbonic acid gas, water or mineral salt directly, thereby avoided secondary pollution oxidation operation with oxidisability.Generally speaking, great majority are that pyrolytic reaction and free radical reaction are simultaneous in the phonochemical reaction.As seen, the ultrasonic cavitation degraded mainly is by high temperature pyrolysis, the approach of free-radical oxidn, thus hyperacoustic mechanical effect can make the carbon bond generation fracture on the macromolecular main chain make the polymer degraded simultaneously.
Ultrasonic wave air supporting machine of the present invention, its working process is: handle the rear section clear water, through air dissolved pump, mix with air in the pressurization water inlet dissolving, air dissolves is in water, and molten gas efficient at this moment reaches more than 80%; Air in the dissolving adds in the dissolving by automatic control of liquid level instrument control air compressor machine automatically; The dissolved air water that dissolving comes out, this moment, the pressure of dissolving was 0.3～0.4Mpa, through reliever, the decompression of dissolved air water pressure is discharged, make dissolved air water pressure be kept to zero or negative pressure, the air that is dissolved in the water discharges from water, forming particle diameter is a large amount of micro-bubbles of 20～50um, microbubble is with the suspended substance combination in the sewage, and the part microbubble just is grown directly upon in the suspended substance, and bubble adheres on the fine suspension by surface tension, the proportion of suspended substance in sewage is diminished, form whole proportion less than 1 situation, floating according to law of buoyancy to the water surface, form a large amount of scum silica frost.By chain type slag scraper, gravity flow deslagging funnel device scum silica frost is removed, realized solid-liquid separation, sewage is purified.
Ultrasonic wave air supporting machine of the present invention, simple in structure, use easy to operately, pollution-free, energy consumption is low, but continuous high-efficient dispose of sewage.
Ultrasonic wave air supporting machine of the present invention, can more effective breakdown of emulsion deoil, remove suspended substance, and to the waste water of biochemical difference by hyperacoustic " cavitation " principle, can break ring, scission of link to the macromolecular substance of waste water and resolve into and be easy to biochemical small-molecule substance, effectively improve the biodegradability of waste water.
Ultrasonic wave air supporting machine of the present invention, the oil removal efficiency height can effectively be removed colourity, improves the biochemical of waste water, waste water COD clearance height, organic rate of recovery height, the molten gas efficient of air dissolving system is greater than 80%.
In sum, ultrasonic wave air supporting machine of the present invention, simple in structure, to use easy to operately, pollution-free, energy consumption is low, and the oil removal efficiency height is removed colourity, improves the biochemical of waste water, waste water COD clearance height, organic rate of recovery height, molten gas efficient height.
