Purpose:
Dissolved air flotation machine is a kind of solid-liquid separation equipment commonly used in sewage treatment industry. It can effectively remove suspended solids, grease and gum substances in sewage. It is the main equipment for sewage pre-treatment. Dissolved air flotation machine is widely used in petroleum, chemical industry, printing and dyeing, papermaking, oil refining, leather, steel, mechanical processing, starch, food and other sewage treatment.
working principle
FLQF combined air flotation tank is composed of air flotation tank body, dissolved air system, dissolved air return pipeline, dissolved air water release device, slag scraping device (combined type, traveling type and chain plate type can be adopted respectively according to the needs of users) and electric control cabinet. Air floatation separation technology refers to that air and water under a certain working pressure make the gas melt into the water to a large extent, strive to be in a saturated state, and then release the formed pressure dissolved air and water through decompression to produce a large number of micro bubbles, fully contact with the suspended flocs in the water, make the suspended flocs in the water adhere to the micro bubbles, and float to the water surface with the bubbles to form scum and scrape off the scum, so as to purify the water quality.
Single processing capacity: 1 ~ 100m3 / h Type: partial reflux dissolved air flotation High efficiency air dissolving system provides high-quality air dissolving water with large amount of bubbles and small diameter Select different reflux ratio according to different raw water quality to ensure the removal rate Stainless steel chain type foam scraper has good reliability, and the number of scrapers can be increased or decreased to adapt to different sludge volumes In order to reduce land occupation and cost, coagulation reaction tank, clean water tank and other process equipment can be selected for joint construction The control equipment with the electromechanical control cabinet operates fully automatically according to the setting mode Optional materials: carbon steel epoxy anticorrosion, carbon steel lined with FRP, stainless steel SS304
