Dissolved air flotation machine

Dissolved air flotation machine equipment Qingdao Ibero-American Environmental Engineering Co., Ltd. is mainly used for solid - liquid or liquid - liquid separation of a water treatment and environmental protection equipment products. Flotation device is produced by the dissolved air in the water delivery system and a large number of fine bubbles, making it adhere to the wastewater close to the density of water, solid or liquid particles, resulting in the state of the overall density less than water, and rely on buoyancy goes up to the surface, so as to achieve a solid - liquid or liquid - liquid separation purposes.

II. Working principle: air into the air tank through the jet by the air compressor means is brought into the dissolved gas cylinders, is forced under pressure 0.35Mpa dissolved in water to form dissolved gas and water, to the flotation tank. In the case of a sudden release of dissolved air in water to precipitate, forming a group of a large number of micro air bubbles, with pumping over and after dosing are flocculated sewage full contact suspension, and rising slowly during adsorption flocculation of suspended solids in good to float to the surface density decline, reaching to remove SS and CODcr purposes.
Three. Feature
1. Dissolved air pump suction side edge suction, pressure mixing pump, high efficiency gas-liquid dissolution, fine bubbles ≤30um.
2. Low voltage operation, dissolved air efficiency up to 99%, the release rate of 99%.
3. Microbubbles and efficient adsorption of suspended particles and improve the SS removal.
4. Dissolved gas dissolved in water efficiency of 80-100% higher efficiency than conventional DAF 3 times.
5. Pressure - volume curve is flat, easy to implement automatic control, easy to operate and easy to maintain, low noise.

Four. The main structure
1, flotation machine: round steel structure, is the main and central sewage processor, internally by the release, a uniform, a sewage pipe, outlet pipe, sludge tank, scraper system components.
Release flotation machine placed central location, is a key component in producing micro bubbles. Dissolved gas cylinders to the dissolved gas and water and wastewater mixed here, a sudden release, produce vigorous agitation and vortex, forming a diameter of about 20-50UM microbubbles, and adhered to the waste water in the flocs, thus reducing flocs the proportion of the rise in water thoroughly separated. Uniformly distributed in the lower outlet box, and the box is connected to the upper part of the overflow, underflow outlet has water through a vertical adjustment handle executives, easy to adjust the water level in the tank. Evacuated tube is mounted in the bottom of the box, for discharging the precipitate deposited on the bottom. The box has a sludge tank, scraper, scraper constantly rotate continuously blown inside the floating sludge sludge trough, gravity sludge tanks to the tank.
2, dissolved air system has the dissolved gas cylinders, cylinders, air compressors, high pressure pump composition, dissolved gas cylinders is the most critical part of the system, work is not sufficient to achieve contact with the air, accelerating the air dissolved. It is a closed pressure steel tanks, internal baffle design, spacer, can accelerate the diffusion of air and water, the mass transfer process, improve the efficiency of dissolved air. 783D1CB0D32A14D296A62D78A8B58E

3, Pharmacy tank: steel round cans, used to dissolve the storage of liquid, which was dissolved two tanks with stirring device, the other two for drug storage tanks, volume processing capabilities with the size of the package.

Five, the scope of dissolved air flotation device Scope:
   With a variety of heavy metal ions from wastewater treatment, oily wastewater treatment, tannery wastewater treatment, chemical wastewater treatment, paint wastewater treatment, food wastewater treatment, sludge biological treatment, water treatment and fiber separation papermaking wastewater recycling, printing and dyeing wastewater treatment, plating, etc. , low temperature and low turbidity of ground water, surface water containing algae, a variety of other solid waste and liquid separation.
