Card, the use of flotation device just can change this phenomenon.
And existing flotation device is to manage to make to produce substantial amounts of microbubble in water, to form water, gas and to be removed material
Three-phase mixture, under the common effect of the many kinds of forces such as interfacial tension, bubble rising buoyancy and hydrostatic pressure difference, promotes fine gas
After bubble sticks in removed tiny oil droplets, because adherend density floats less than the water surface, so that float in water, oil
The device that grain etc. is removed by separation.Existing flotation device, mainly has flotation tank, bubble generator, and bubble generator has one
Pressure air-dissolving room, pressure air-dissolving room is respectively turned on to be provided the air compressor machine of air into it, provides the force (forcing) pump of liquid stream for it, by pneumatics
Machine and force (forcing) pump, respectively to pressure air-dissolving indoor injection air stream and liquid stream, carry out gas-liquid mixed and form gas in pressure air-dissolving indoor
Being sent to flotation tank after liquid mixed flow, this mixing molten gas mode not only takes up room greatly, and the bubble produced is relatively big, can be right
It is poor that the release device that follow-up air supporting brings adverse effect, flotation device to be used there is also effect of energy dissipation, and turbulent phenomenon is serious, release
The defects such as the bubble diameter gone out is big and uneven, and easily block, can only be used to the occasion that flow is little, have a strong impact on air supporting effect
Rate.
