The invention relates to a cyclone air flotation apparatus, and belongs to the field of water treatments. The cyclone air flotation apparatus comprises a vertical cylinder, wherein one side of the cylinder is provided with a water inlet, a gas inlet and a reflux port, the bottom end of the tapered bottom of the cylinder is provided with a residue discharge port and an emptying port in a parallel manner, the other cylinder side close to the bottom is provided with a water outlet, the position close to the top end is provided with an overflow port, a center cylinder is arranged in the center of the cylinder and is divided into an upper chamber, a middle chamber and a lower chamber, the upper chamber is a residue collection tank, an upper chamber pipeline is connected with the residue discharge port, a micro gas bubble generator is arranged inside the middle chamber, the periphery of the middle chamber is distributed with a plurality of branch pipelines, the end portions of the branch pipelines are provided with injectors, the lower chamber is a water collection tank, and the residue discharge port on the bottom and the overflow port on the upper portion are normally opened during running. According to the present invention, after entering the air flotation cylinder, water requiring a treatment performs a cyclone movement on the water inlet horizontal level in the cylinder by using the hydrodynamic force so as to make the light phase suspension granules continuously agglomerate to the center, and rapidly move upward and flow into the residue collection tank under the effect of elevation buoyancy of micro gas bubbles injected by the injectors distributed on the periphery of the built-in micro gas bubble generator so as to achieve water purification and pollutant collection and treatment.

Description

A kind of cyclone air-flotation device
Technical field
The present invention relates to water treatment field, relate in particular to cyclone air-flotation process field.
Background technology
In feedwater and draining, process, Industrial Wastewater Treatment particularly, except the pollutent of heavy particle is to adopt the precipitator method, nearly all lightweight suspension thing and deliquescent pollutent are mostly to adopt the air-float method that dosing is flocculated to carry out isolation of purified.Traditional flat flow type air-float pool almost spreads all over engineering of water treatment in all parts of the country.But due to low content of technology, power consumption is large, processing cost is high and investment and floor space large, be not only difficult to reach materialization and give processing effluent index, and because power consumption is large, become one of carbon emission key monitoring object.
The technology of the present invention belongs to international forward position level at present, and domestic industry only CNOOC has the similar technical equipment of introducing Western European countries company, not yet has other entity and individual that research and develop this project core technology and be successfully applied to engineering practice.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, the Integral cyclone air-floating apparatus of a kind of compact construction, deft design is provided.
Key problem in technology of the present invention is also to save traditional pneumatically supported coagulation, coacervation, chemicals dosing plant, and saves independent automatic control or manual molten gas equipment in traditional air-flotation system.And invented a kind of energy-saving microbubble generator being built in main frame cylindrical shell, pass into pressurized gas and low-pressure water and just can produce microbubble, and by injector to periphery gather microbubble, make to be suspended in and after the liquid or solid particle of processing in water is adsorbed by microbubble, shift to rapidly liquid level gravity and flow into scum silica frost groove and discharge.Its concrete technical scheme is: a kind of cyclone air-flotation device, comprise vertical cylindrical shell, cylindrical shell one side offers water-in, inlet mouth and refluxing opening, cylindrical shell conical lower portion bottom offers slag-drip opening and drain side by side, the nearly bottom of cylindrical shell opposite side offers water outlet, nearly top offers overflow port, it is characterized in that the built-in central tube in described outer cylinder body center, central tube is divided into three chambers of upper, middle and lower, described upper chamber is dreg collecting slot, upper chamber's pipeline connects slag-drip opening, in described middle chamber, be provided with microbubble generator, several laterals of middle chamber circumferential distribution, described lateral end is provided with injector, described lower chambers is water leg.
As preferably, described overflow port place is provided with overflow groove.
As preferably, described water-in pipeline with along cylindrical shell cylindrical, tangentially arrange.
A kind of cyclone air-flotation device treatment process, it is characterized in that comprising the following steps: pending water is entered after cylindrical shell by water-in, utilize the water power of self, make the horizontal bedding of intaking in urceolus make swirling motion, a suspension material for light phase is constantly gathered to center, and under the effect of the rising buoyancy of the microbubble ejecting at the injector of built-in microbubble generator circumferential distribution, upwards advection enters dreg collecting slot rapidly, and discharges by slag-drip opening.
Beneficial effect of the present invention: because the present invention has adopted the centrifugal principle of water body swirling motion, so can be in less container, improve intake pressure, realize and force separation, complete faster solid-liquid separation separated with liquid liquid, thereby make pollutent Neng Cong center of circle district by floating upper collection rapidly, thereby reach the object purifying water.
Announcement of the present invention, by opening the further upgrading of domestic energy-conserving and environment-protective industrial technology, has drive environmental protection industry, and even improves National Nature state of ecological environment, minimizing carbon emission! Promote the strategic meaning of industrial technology level.In national environmental protection department, require further to improve after the policies and measures appearance of water surrounding, mark transformation will be proposed by the sewage work of the water sources such as domestic many lakes, reservoir and most cities, working surfaces also further is mentioned in the requirement of reusing sewage, and the improvement that the technology of the present invention will boosting water surrounding is made contributions!
The present invention is the technology that these industries are badly in need of most in water Pollution risk and the more outstanding industry of impact, open Mining, refining of petroleum as oil! Announcement of the present invention and project implementation will make the import situation of this high-grade cyclone air-flotation in recent years occur to change to the direction of production domesticization, thereby make the technology of China's water treatment and the gap of developed country accelerate to dwindle.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
