Description

A kind of UW air supporting oil removal plant
Technical field
The utility model relates to a kind of UW air supporting oil removal plant, belongs to oily(waste)water processing technology field in the environment protection.
Background technology
The air supporting facture is exactly logical people's air in waste water; And separate out from water with the micro-bubble form and to become carrier; Pollution substances such as the oil in water emulsion in the waste water, small suspended particle are sticked on the bubble; With floating to the water surface on the bubble, form foam one gas, water, particle (oil) three-phase mixtinite, through collecting the purpose that foam or scum silica frost reach separating impurity, purify liquid waste.Through obtaining small bubbles; The diameter of general tiny bubble is 10-100 μ m; Form water-gas-grain three-phase mixed system, micro-bubble becomes carrier, and bubble is separated out the pollution substance formation gas-agglomerate tabling that adheres in the water and selected body to emerge to become scum silica frost from water; Scum silica frost is scraped off by scraping machine, and then system water is cleaned discharge.Since the density of air be merely water density 1/755, having adhered to some amount, to pollute the bubble system global density of impurity little more than the density of water, then the ascent rate of system also just increases, i.e. the principle of flocs with gas come-up.
Oily(waste)water adopts air supporting method treatment effect better, and skill has been developed various ways on the flotation waste water treatment.Producing the bubble mode by it can be divided into: gas distribution method air supporting (comprising the broken gas method of rotor, micropore gas distribution method, impeller dispersed-air flotation etc.) electrolytic gas float glass process; Biochemical air supporting method (comprising biological aerogenesis float glass process, chemical aerogenesis air supporting); Dissolved air air supporting (comprising vacuum air supporting method, the full air-dissolved of pressure air supporting method, part air-dissolved and partial reflux air-dissolved).The whole bag of tricks each has its relative merits.For example: pressurized dissolved air flotation commonly used has the reliever blockage problem.Although existing reliever has designed many clogging-preventing measures, but still undesirable, also can occur frequently stopping up.
The utility model content
The purpose of the utility model is to provide a kind of UW air supporting oil removal plant.The air that this device utilizes the ultrasonic grinding aeration to be fed forms tiny bubble, and bubble combines with oil droplet in the process that rises, and along with tiny bubble floats, the come-up back gets in water movement and strains the foam device in conjunction with the back oil droplet, and oil droplet is removed.This device is owing to its particular structural, and current can flow at the device internal recycle in the cohesive process of oil droplet and bubble, guarantee fully to combine.
The purpose of the utility model can realize through following technical scheme:
A kind of UW air supporting oil removal plant; Comprise tank; Be provided with baffle plate in the described tank, described baffle plate is divided into ultrasonic dehydration chamber and air flotation separating chamber with tank, and described ultrasonic dehydration chamber and air flotation separating chamber are connected through the water pipe that is located at the baffle plate bottom; Top, described ultrasonic dehydration chamber is provided with water inlet pipe, the distribution device that bottom, described ultrasonic dehydration chamber is respectively equipped with ultrasonic transmission device, inlet pipe and is connected with inlet pipe; The middle and upper part of said air flotation separating chamber is provided with water outlet; The indoor water-distributing device that is connected with water inlet pipe that also is provided with of described ultrasonic dehydration; Described baffle plate is the bending baffle plate, and the epimere of said baffle plate vertically is provided with, and hypomere is obliquely installed and tilt angle alpha is 40 °~70 °; The vertical height of said water-distributing device is identical with the vertical height of said baffle plate hypomere sloping baffle, and the upper end of said baffle plate is provided with strains the foam groove.
The tilt angle alpha of said baffle plate hypomere is preferably 60 °.
Above-mentioned UW air supporting oil removal plant, it is that the said cell wall of straining the adjacent side with the ultrasonic dehydration chamber of foam groove is lower, the opposite side cell wall is higher.
Above-mentioned UW air supporting oil removal plant, it is that described ultrasonic transmission device is located at the top of distribution device.
During operation, as long as open water-in, ultrasonic generating unit and distribution device.
The beneficial effect of the utility model is:
The bubble that aeration provides is ground into tiny bubble under the UW effect; In these bubbles and the device from top to bottom the oil droplet in the mobile water mix mutually and combine, the oil droplet come-up, overflow is to straining the foam groove; Because the special construction of baffle plate in the device; Current can flow in this partial rotation under the promotion of bubble, and oil droplet and tiny bubble fully combine, and the direction of current then drives foam stream to straining the foam groove.
Evidence: in the waste water access equipment of 700mg/L, opening frequency is 20kHz with oleaginousness, the UW of power 1200W and bubbling air, and after treatment, oil removal rate reaches more than 95%.
