Dissolved air flotation equipment is a device that removes suspended solids, grease and various colloidal substances in various industrial and municipal sewage. The equipment is widely used in oil refining, chemical industry, brewing, vegetable oil production and refining, slaughtering, electroplating, printing and dyeing and other industrial wastewater and municipal wastewater treatment.
Users who have used dissolved air flotation equipment should know that the dissolved air flotation equipment is composed of an air flotation tank, a solvent system and a pharmaceutical tank. The air flotation tank: a circular steel structure, is the main body and core of the sewage treatment machine. , The interior is composed of a releaser, a uniform distributor, a sewage pipe, a water outlet pipe, a sludge tank, and a scraper system. The releaser is placed in the middle of the air flotation machine and is a key component in the production of microbubbles. The solution gas and water from the dissolved gas tank is fully mixed with the wastewater here, and is suddenly released, resulting in violent agitation and eddy currents, forming micro-bubbles with a diameter of about 20-80um, so that the flocs adhered to the water rise and the clean water is completely separated. The homogenizer has a conical structure and is connected to the releaser. Its main function is to evenly distribute the separated clean water and sludge in the tank. The water outlet pipes are evenly distributed in the lower part of the tank body, and are connected to the upper overflow of the tank through an upright main pipe. The overflow outlet is provided with a water level adjustment handle, which is convenient for adjusting the water level in the tank. The sludge pipe is installed at the bottom of the tank to discharge the sediment deposited on the bottom of the tank. There is a sludge tank on the upper part of the tank, and there is a scraper on the tank. The scraper rotates continuously to continuously scrape the floating sludge to the sludge. In the tank, it flows to the sludge tank by itself.
And the dissolved air system: the dissolved air system is mainly composed of a dissolved air tank, an air storage tank, an air compressor, and a high-pressure pump. The dissolved air tank is a key part of the system, and its function is to achieve full contact with air and accelerate air dissolution. It is a closed pressure-resistant steel tank with baffles and spacers designed inside, which can accelerate the diffusion and mass transfer process of air and water and improve the efficiency of dissolved air.
Then the medicine tank: used to dissolve and store the liquid medicine, two of which are dissolving tanks with stirring devices, and the other two are medicine storage tanks, and the volume is matched with the processing capacity.
