Description
Technical Field
The utility model relates to efficient air floatation equipment, and belongs to the technical field of air floatation machines.
Background
The air floating machine is a machine which utilizes small bubbles or micro-bubbles to float impurities in a medium out of the water surface. The air floating device can be used for small water with the specific gravity close to that of water and is difficult to sink or float by the dead weight of the small water.
The existing equipment for removing suspended matters in sewage comprises a coagulation sedimentation tank and an air flotation tank, wherein the coagulation sedimentation tank has higher removal efficiency on suspended matters with higher density; the air supporting equipment generally has higher efficiency of getting rid of to the less suspended solid of density, if have the great and less suspended solid of proportion in the waste water simultaneously, then air supporting treatment effeciency can obviously reduce because the difficult come-up of the great suspended solid of proportion can be along with rivers outflow, and when current air supporting equipment handled this type of waste water, treatment effeciency reduced.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides high-efficiency air floatation equipment, wherein a precipitation area is added behind a coagulation stirring area of an air floatation tank, and a dissolved air releaser is added in an air floatation separation area for enhancing the treatment effect and improving the removal efficiency.
The utility model is realized by the following technical scheme: the utility model provides a high-efficient air supporting equipment, includes the air supporting disengagement zone, dissolves gas pitcher, air compressor machine, scrapes sediment machine and mixer, its characterized in that: the air flotation separation area and the stirrer are provided with a precipitation area therebetween, the precipitation area is internally provided with an inclined tube filler, the bottom of the precipitation area is provided with a precipitation area mud bucket, an air flotation water inlet of the air flotation separation area is arranged on one side of the stirrer, a dissolved air tank is connected with an air compressor and is connected with a dissolved air release pipeline, an outlet of the dissolved air release pipeline is connected with a dissolved air releaser arranged on the bottom of the air flotation separation area, and a scum collecting tank and an air flotation water outlet are also arranged on the air flotation tank.
The scum scraper is connected with the scum scraper and the scum scraper chain, the scum scraper and the scum scraper chain are arranged at the top of the air floatation separation area, and the scum scraper chain scrape flocs into a scum collecting tank through the driving of the scum scraper.
The top of the settling zone is provided with a settling zone effluent weir.
The utility model has the beneficial effects that: the settling zone is added in the air floatation machine, and the dissolved air releaser is added in the air floatation separation zone to strengthen the removal effect, thereby improving the air floatation treatment efficiency.

FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a sectional view a-a of fig. 1.
In the figure: 1. an air flotation separation area; 2. a dissolved air tank; 3. an air compressor; 4. a slag scraper; 5. a blender; 6. a settling zone; 7. filling the inclined tube; 8. a settling area mud bucket; 9. a dissolved air releaser; 10. a dissolved air release conduit; 11. a scum collecting tank; 12. an air flotation water outlet; 13. a slag scraping plate; 14. a slag scraping chain; 15. and a settling zone effluent weir.
Detailed Description
As shown in fig. 1 and 2, the high-efficiency air flotation device comprises an air flotation separation zone 1, a dissolved air tank 2, an air compressor 3, a slag scraper 4 and a stirrer 5, and is characterized in that: the air flotation separation area 1 and the mixer 5 between be equipped with the settling zone 6, be equipped with pipe chute filler 7 in the settling zone 6, the bottom of settling zone 6 is equipped with settling zone mud bucket 8, the air flotation water inlet setting of air flotation separation area 1 is in 5 one sides of mixer, dissolve gas jar 2 and 3 connection dissolved air release pipeline 10 of air compressor machine, dissolved air release pipeline 10 exit linkage sets up the dissolved air releaser 9 in air flotation separation area 1 bottom, still be equipped with dross collecting vat 11 and the air flotation delivery port 12 on the air flotation tank 1.
The scum scraper 4 is connected with a scum scraper 13 and a scum scraper chain 14, the scum scraper 13 and the scum scraper chain 14 are arranged at the top of the air floatation separation area 1, and the scum scraper 13 and the scum scraper chain 14 are driven by the scum scraper 4 to scrape flocs into a scum collecting tank 11.
The top of the settling zone 6 is provided with a settling zone effluent weir 15.
The working principle is as follows: the sewage enters a coagulation stirring area for coagulation stirring in the operation process of the air floatation equipment, flocs are formed in the stirring area, then the sewage enters a settling area 6, an inclined tube filler 7 is arranged in the settling area 6, suspended matters with higher density sink to a settling area mud bucket 8, the non-settled suspended matter flocs enter a dissolved air release area along with water flow, the dissolved gas releaser 9 in the releasing area generates a large amount of micro bubbles, the micro bubbles and water flow upwards together and are attached to the suspended flocs and enter the separating area, the flocs attached with the bubbles rise to the water surface and are scraped into a scum collecting tank 11 by a scum board 12, part of flocs which are not attached with bubbles in the separation area do not float to the water surface, the bubbles are provided by a dissolved air releaser 9 added in the separation area, this part of the flocs that have not floated up can be brought to the water surface and then scraped into the scum collecting tank 11 together with the scum that has been on the water surface by the scum board 12. The whole operation process can be automatically controlled through an automatic control program.
