Technical field
The present invention relates to technical field of environment protection equipment, more particularly, to a kind of unpowered flotation device of wastewater treatment.
Background technology
For removing the sundries such as solid suspension, grease in various industry and municipal wastewater, if continuing to use traditional precipitation
Method, effect is necessarily very poor, and especially in winter under cryogenic conditions, since coagulation and hydraulics deteriorate, treatment effect is more difficult to ensure
Card, the use of flotation device can just change this phenomenon.
And existing flotation device is to try to make to generate a large amount of microbubble in water, to form water, gas and be removed substance
Three-phase mixture promotes fine gas under the collective effect of many kinds of force such as interfacial tension, bubble rising buoyancy and hydrostatic pressure difference
After bubble is adhered in the tiny oil droplets being removed, float because bonding volume density less than the water surface, to make suspended matter, the oil in water
Grain etc. is by the device of separation removal.Existing flotation device mainly has flotation tank, bubble generator, bubble generator to have one
Pressure air-dissolving room, pressure air-dissolving room is respectively turned on the force (forcing) pump for providing the air compressor machine of air for it, providing liquid stream for it, by pneumatics
Machine and force (forcing) pump inject air stream and liquid stream into pressure air-dissolving room respectively, and gas-liquid mixed is carried out in pressure air-dissolving room and forms gas
Flotation tank is sent to after liquid mixed flow, not only occupied space is big for this molten gas mode of mixing, and the bubble generated is larger, can be right
Follow-up air supporting brings adverse effect, and that there is also effect of energy dissipation is poor for release device used in flotation device, and turbulent phenomenon is serious, discharges
The defects of bubble diameter gone out is big and uneven, and easily block, the small occasion of flow is can only be used to, air supporting effect is seriously affected
Rate.
