Abstract
The invention relates to a jet suction flotation device, and relates to the field of wastewater treatment. The invention especially relates to a design of a flotation device used in wastewater treatment. Aiming at problems of high energy consumption, complicated structure, and difficult operation and maintenance of an existing impeller suction flotation device, the invention provides the jet suction flotation device with the advantages of simple structure and safe operation. The flotation device comprises a device housing. A separation chamber is in the middle in the housing. An annular despumation chamber is arranged on the periphery in the housing. The despumation chamber is open on the upper part. A despumation device is arranged at the opening. According to the jet suction flotation device, the housing is communicated with a circulation water pipe at the center. A liquid-gas jet pump is arranged on the circulation water pipe on the end positioned inside the jet suction flotation device. The liquid-gas jet pump communicates with a gas inlet. The jet suction flotation device has the advantages of large processing capacity, low energy consumption, small land occupation, no moving parts, convenient maintenance, safe operation, and no secondary pollution.
Description
Technical field
The invention belongs to field of waste water treatment, particularly relate to the design of floatation equipment in wastewater treatment.
Background technology
Impeller induced air floatation device, as the induced air floatation device in wastewater treatment, since appearance, due to small volume, stable operation, without secondary slugs process and pollution problem, has thus obtained wide sending out and has applied in the sewage disposal of oilfield exploitation and refinery; But this flotation unit is in actual moving process, there is the problems such as energy consumption is large, complex structure, operating maintenance difficulty, inspiratory capacity is few, air bubbles dispersion is poor, scum silica frost is difficult.
Summary of the invention
The object of this invention is to provide a kind of structure simple, the injection induced air floatation device of operational safety.
The present invention is achieved by the following technical programs: a kind of injection induced air floatation device, comprise crust of the device, be separate chamber in the middle of enclosure, enclosure surrounding is provided with annular separator, separator's upper opening, opening part is provided with scum dredger, and described injection induced air floatation crust of the device central authorities are communicated by circulating pipe, circulating pipe is positioned at injection flotation unit one end and is provided with liquid-gas jet pump, and liquid-gas jet pump is also communicated with inlet mouth.
The present invention has following beneficial effect:
This injection induced air floatation plant energy consumption is low, floor space is little, movement-less part, easy to maintenance, operational safety, non-secondary pollution, be with a wide range of applications.
Accompanying drawing explanation
Fig. 1 is injection induced air floatation device schematic diagram of the present invention.
In figure: 1. separator, 2. shell, 3. scum dredger, 4. inlet mouth, 5. circulating pipe, 6. liquid-gas jet pump, 7. separate chamber.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
Specific embodiment: as shown in the figure, for injection induced air floatation device of the present invention, comprise shell 2, shell 2 bosom is separate chamber 7, and shell 2 inside circumference is provided with annular separator 1, separator 1 upper opening, opening part is provided with scum dredger 3, described injection induced air floatation crust of the device 2 central authorities are communicated by circulating pipe 5, and circulating pipe 5 is positioned at injection flotation unit one end and is provided with liquid-gas jet pump 6, and liquid-gas jet pump 6 is also communicated with inlet mouth 4.
Concrete treating processes is: the recirculated water of pressurization is under the suction function of liquid-gas jet pump 6 high-speed jet, gas by inlet mouth 4 is brought in liquid, and it is mixed in the trunnion of liquid-gas jet pump 6, gas forms small bubbles, discharge after the supercharging of liquid-gas jet pump 6 diffuser tube and be distributed in water, the enrichment of oil droplet bonding floating, through the effect of scum dredger 3, the oil slick on removing top.
This injection induced air floatation device, treatment capacity is large, energy consumption is low, floor space is little, movement-less part, easy to maintenance, operational safety, non-secondary pollution.
Above content is the further description done the present invention in conjunction with concrete embodiment, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all should be considered as belonging to protection scope of the present invention.
