In general, efficient air floating device is mainly composed of two parts, part is pressurized dissolved air and release system, the other part is air-float pond, the former including pump, water ejector, dissolving tank, dissolved gas, dissolved gas main pipe and efficient air-flotation nozzle, etc., which includes adsorption, separation, scraping the slag and drainage and other parts.
In practice, in addition to these two parts, there are some supporting device, including sewage pump, the coagulation reaction tank and sludge treatment etc, including sewage pump is a must, and the coagulation reaction tank can choose according to the needs of the water quality.
Understand the composition of the efficient air floating device, the following simple said its technical performance requirements, specific as follows.
Job stress: efficient air floating device work pressure average of 0.3-0.35 MPa.
Pump: usually adopts single-stage centrifugal pump, the suction pipe is floating pool backflow pipe between the outlet and the pump inlet.
Water ejector: mainly used for just the right amount of air inhaled into the dissolving tank, including inlet valve and inlet valve and other components.
Dissolving tank: mainly used for dissolving air, thus forming a dissolved air water, general pressure gauge in the dissolving tank, used to display the pressure. Moreover, it is at the bottom of the valve, emptying operations.
Dissolved air, dissolved gas main pipe: dissolved air main pipe is connected with the outlet of the dissolved gas, which has a number of dissolving the trachea; Mounted on the dissolved air pipe union, it can convenient branch pipe for dismantling.
Scraping the slag machine: usually choose machine, rotary scraping the slag can be scrape scum, it usually equipped with a speed reducer and attention when use reducer to replace a lubricating oil every six months.
Out of the gate slot: it can be used to adjust the gas floated to the surface of the water level.
Drain pipe: the function is to drainage operation of floating pool, or the emptying of the water in the pool. Therefore, efficient air floating device is working, the valve should be closed.
