Advection type dissolved air flotation machine
Advection type dissolved air flotation machine price wastewater treatment equipment water treatment environmental protection equipment products
First-class dissolved air flotation machine device is mainly used for solid-liquid or liquid A water treatment environmental protection equipment product for liquid separation. The air flotation device generates a large number of fine bubbles in the water through the dissolved air and release system, causing them to adhere to solid or liquid particles with a density close to that of water in the wastewater, resulting in a state where the overall density is less than that of water, and it relies on buoyancy to make it rise. to the water surface to achieve the purpose of solid-liquid or liquid-liquid separation.
The second operating principle is that the air sent to the air tank by the air compressor is brought into the dissolved air tank through the jet device, and is forced to dissolve in the water under force to form dissolved air water, which is sent to the air flotation tank. In the case of sudden release, the air dissolved in the water precipitates and forms a large number of microbubbles, which fully contact the suspended solids in the pumped and flocculated sewage after addition of chemicals, and are adsorbed in the slowly rising process. The flocculated suspended solids are reduced in density and float to the water surface to achieve the purpose of removing and.
Three points
The air pump sucks in water and air at the same time, and the pressurized gas-liquid mixture in the pump dissolves fine bubbles with high efficiency.
Operating under high pressure, the gas dissolving efficiency is high and the release rate is high.
The efficient adsorption of bubbles and suspended particles improves the removal effect.
The air-water dissolution efficiency is several times higher than that of traditional dissolved air flotation.
The force capacity curve is flat, easy to realize automatic control, easy to operate and maintain, and low noise.
Four Essential Structures
The circular steel structure of the air flotation machine is the main body and core of the sewage treatment machine. It is internally composed of a releaser, a distributor, a sewage pipe outlet pipe, a sludge tank, a scraper system, etc.
The releaser is placed in the center of the air flotation machine and is a key component for producing microbubbles. The dissolved gas water from the dissolved gas tank is fully mixed with the wastewater here, and is suddenly released, causing violent agitation and vortex, forming microbubbles with a diameter of about 100, which adhere to the flocs in the wastewater, thereby reducing the specific gravity of the flocs and increasing them. , the clean water is completely separated. The water outlet pipes are evenly distributed in the lower part of the tank and are connected to the upper part of the tank through an upright main pipe to overflow. The overflow outlet is equipped with a water level adjustment handle to facilitate the adjustment of the water level in the tank. The drain pipe is installed at the bottom of the tank to discharge sediment deposited at the bottom of the tank. There is a sludge tank on the box, and there is a scraper on the tank. The scraper rotates continuously to continuously scrape the floating sludge into the sludge tank and flow to the sludge pool.
The dissolved air system mainly consists of a dissolved air tank, an air storage tank, an air compressor, and a high-pressure pump. The dissolved air tank is the most critical part of the system. Its function is to achieve full contact with the air and accelerate the dissolution of the air. It is a sealed pressure-resistant steel tank with a baffle spacer designed inside, which can accelerate the diffusion and mass transfer process of air and water and improve the efficiency of dissolved gas.
Medicine tanks are steel round tanks used to dissolve and store medicinal liquids. Two of them are dissolving tanks with stirring devices, and the other two are medicinal storage tanks. The volume is matched with the processing capacity.
5. Scope of application Applicable scope of dissolved air flotation device
Papermaking wastewater treatment and fiber recycling, printing and dyeing wastewater treatment, electroplating, etc. Wastewater treatment containing various heavy metal ions, oily wastewater treatment, tanning wastewater treatment, chemical wastewater treatment, paint wastewater treatment Food wastewater treatment, biological treatment of muddy water, low temperature and low turbidity ground water treatment, algae-containing ground water treatment, solid-liquid separation of various other wastewaters, etc.
