Embodiment
Novel external placed type machinery new air-smashing and dissolving flotation column comprises external placed type machinery new air-smashing and dissolving device 1 and air-flotation column 2, and air-flotation column 2 upper ends one side is equipped with water-in and water-distributing device 6, and the outer end of water-in and water-distributing device 6 is connected with water pump 3 by water pipe; The top of described air-flotation column 2 is equipped with slag scraper 8 and dreg collecting slot 7, and dreg collecting slot 7 is provided with slag-drip opening 9; Dissolved air water import and the distribution device 5 installed in the lower end of air-flotation column 2 join with new air-smashing and dissolving device 1, air-flotation column 2 bottoms are equipped with draining and slag-drip opening 10, the air-flotation column bottom sides is provided with water outlet 4, and water outlet 4 joins by air-flotation column 2 fluid level controllers and water storage tank 11.The profile of air-flotation column 2 can be tower, pond formula, circle, square or other shape.But filling and not filling filler in air-flotation column 2, the material of filling filler can be natural or artificial inorganic materials, organic materials, metallic material, the shape of filler can be Raschig ring, Pall ring, cascade ring, waved plate and filamentary material.The material of making air-flotation column 2 can be inorganic materials, organic materials and metallic material.But can establish the air-flotation column fluid level controller at the water inlet of air-flotation column 2 establishing tank, water outlet.Slag scraper 8 in the air-flotation column 2 can be the many scraper-types of crawler belt, driving single scraper-type, cable traction running type, radially scraper-type sways.The pending water that is to enter air-flotation column 2 can add or adding medicine coagulation not, and coagulated agent can be inorganic flocculating agent, organic floculant and inorganic organic complex flocculation agent and flotation reagent.New air-smashing and dissolving device 1 adopts mechanical pump to produce the high-pressure rotary current.Both single mechanical pump can be adopted at new air-smashing and dissolving device 1, also mechanical pump, gas water separation tank and reliever can be adopted.Slag-drip opening 9 on the described dreg collecting slot 7 can be established one to a plurality of.
When pending water through water pump 3 after water-in and water-distributing device 6 enter air-flotation column 2, for the impact that alleviates water into play even feedwater effect, distributing trough can be set before water-in.In air-flotation column 2, water is in continuous sinking process, and the microbubble of flocculate in a large number particle and a large amount of risings that discharge from the air-water mixture releasing device bumps and adheres to and produce copolymerizing and air-float.Flocs with gas constantly floats because density diminishes, and forms the scum layer at top at last, and is discharged by water outlet 4 at last with the clear water after the flocculation particle separation.Clear water circulation or discharge can be controlled by the air-flotation column grasshopper.Water outlet 4 effusive clear water partial reflux perhaps can directly be replenished as dissolved air water with clear water as the required dissolved air water reuse of mechanical new air-smashing and dissolving device 1.When recirculation water enters mechanical pump in the mechanical new air-smashing and dissolving device 1, the high-pressure rotary water that mechanical pump produces carries out forming dissolved air water behind cutting and grinding and the molten gas to gas, dissolved air water can be directly or after gas-water separation and decompression, enters in the air-flotation column 2 by clear gas releasing device again.Enter dissolved air water in the air-flotation column 2 because of the variation of pressure and environment, dissolved air water enters in the air-flotation column 2 from air-flotation column 2 middle and lower part water-ins and distribution device 5, the microbubble counter current contact that flco in the need treating water or particle discharge with dissolved air water in the segregation section in air-flotation column 2, constantly captured come-up by microbubble and realize that to the outlet of top scum silica frost pulp water separates, clear water effluxes or does recycles such as dissolved air water at the bottom of the post through clear water output 4 by the air-flotation column grasshopper; But at air-flotation column 2 middle and lower part filling fillers, filler can work to reclaim, filter the residue flocs unit.During the filling filler, filler can be natural or artificial inorganic materials, organic materials and metallic material etc.In addition, the bottom is provided with draining and slag-drip opening 10 is respectively applied for the emptying draining and gets rid of sediment.At air-flotation column 2 tops, the Floc in Flotation bulk deposition forms scum layer, therefore will carry out regularly or continuous discharging slag it.Select overflow slag or slag scraper according to scum silica frost character and actual airfloat equipment; Scrape that slag equipment 8 can be the many scraper-types of crawler belt, driving single scraper-type, cable traction running type and the scraper-type that sways radially etc., the scum silica frost that scrapes enters dreg collecting slot 7, is discharged by slag-drip opening 9 at last.Slag-drip opening 9 on the described dreg collecting slot 7 can be one to a plurality of.Must carry out dosing as last and mix and flocculate when pending water enters air-flotation column 2, the selection of medicament is decided by pending water quality and pollutent characteristic.Dosing mixed flocculation mode can be dosing mixed flocculation behind the pump front pump, mechanical stirring mixed flocculation etc.; The selection of medicament can be inorganic flocculating agent, organic floculant, inorganic organic complex flocculation agent and flotation reagent etc., adds the compound type flocculation agent simultaneously and helps reducing dosing and its synergistic effect of performance.(0.2~0.5MPa) rotary water current carries out molten gas and bubble cutting and grinding to gas, and used mechanical pump can be various types of pumps, closes pump, the heterogeneous multistage mixing pump of gas-liquid, sand pump and water pump etc. as gas-liquid multiphase mixing to produce high pressure with mechanical pump.The dissolved air water that mechanical pump produces can be directly, through gas-water separation (voltage stabilizing) jar back or through after the reliever decompression or after gas-water separation buffer tank and reliever reduce pressure, process dissolved air water import 5 enters in the air-flotation column 2 by molten gas releasing device again; The bubble that dissolved air water is produced after releasing device discharges is small and stable, and molten gas releasing device plays even gas distribution effect simultaneously; Molten gas releasing device can be the reliever of simple openings such as tubulose, strip, dendritic, ring-type, also can be molten gas releasing device.The utility model is applicable to feedwater, trade effluent and municipal sewage treatment, and the processing except that waste water such as algae, dyeing waste water, slaughterhouse wastewater, bath wastewater, oily(waste)waters of being specially adapted to feed water is applicable to recycled writing paper deinking flotation and fine mineral flotation simultaneously.As pottery, plastics, resin, steel mesh, steel wool etc.; As steel, glass reinforced plastic, synthetic glass, concrete and other materials.The technical division that the utility model is not described in detail is divided into known technology.
