Description
Technical field
The present invention relates to a kind of blue-green algae treatment facility, specifically is a kind of algae-laden water separating and dehydrating machine, and it is mainly used in the blue-green algae that produces in lake, the landscape water is carried out algae moisture from, water quality detoxification and algae-residue processed.
Background technology
After the summer has set in, the frequent continuity high temperature and little rainfall of weather, the water body in lake and the view can't upgrade for a long time, add chemical industry algae water, life algae water and the infringement of excessively culturing, make the eutrophication in lake, the landscape water serious, easily cause blue algae bloom, form natural calamity.
The blue-green algae formal name used at school is blue toxin, toxin in the blue toxin is divided into a variety of, and one of them is categorized as hepatotoxin and neurotoxin, and they are known meeting invasion and attack liver and neural toxin, the toxin of another classification has spread effect to skin, and the algae toxin has water-soluble and hear resistance.Soluble in water, methyl alcohol or acetone, non-volatile, anti-pH changes.Its dissolubility in water is greater than 1g/L, the chemical property quite stable.Heating is boiled all and toxin can not be destroyed, and can not remove; The coagulating sedimentation of running water treatment process, filtration, chlorination can not be removed it.Caused more than 100 acute liver function fault in Brazil in 1996, at least 50 people die from the acute effect that the algae toxin produces in 7 months, cause concern highly visible.On May 28th, 2007, Taihu Lake area blue-green algae large tracts of land outburst in Wuxi causes Wuxi City running water severe contamination, and the urban district pure water is made a mad rush for, though government in time takes measures, the life to the people produces very big influence.
At present, prior art from generally adopting flocculation-air floating method and centrifugal dehydration method clustered operation, promptly adopts flocculation reactor and centrifugal dehydrator to combine to algae moisture.Wherein centrifugal dehydration method is long to the time that algae-residue carries out the processed needs, adds that motor speed is higher, and the power consumption of generation is also more, and the economy of handling blue-green algae is relatively poor.And the centrifugal dehydrator volume ratio is bigger; need to be equipped with heavy-duty motor; it is unsuitable for vehicle-mounted or boat-carrying; and the zone of blue algae bloom is unfixed, and particularly for the bigger lake of area, the often regional and treating stations that the outburst of blue-green algae large tracts of land takes place is separated by remote; deliver to treating stations again after algae water need being collected; perhaps lay long-distance pipe, so reduced ability and the speed of handling crisis, and economy is relatively poor.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, it is little to the invention provides a kind of volume, and energy consumption is low, and is suitable for the algae-laden water separating and dehydrating machine of vehicle-mounted or boat-carrying.
For achieving the above object, algae-laden water separating and dehydrating machine of the present invention comprises shell, central shaft, micropore sucker, vacuum blowback dish, vavuum pump and screw pump, and the described algae dewaterer shell that removes is provided with water inlet, and central shaft is bearing in except that in the algae dewaterer shell; Some groups of coaxial being installed on the central shaft of micropore sucker radially are provided with the pipeline that communicates with the axial passage of central shaft on it; Stretch out except that algae dewaterer shell at the central shaft two ends, the one end is connected with drive unit, the other end is provided with channel outlet, the coaxial end that is fixed on the central shaft channel outlet of vacuum blowback dish is axially arranged with the sound air seal set on vacuum blowback dish and central shaft, be provided with the blowback groove on vacuum blowback dish upper semi-circle side face, the lower half circle side face is provided with the vacuum bothrium, wherein the blowback groove links to each other with external air source, and the vacuum bothrium links to each other with vavuum pump, and the screw rod pump intake stretches into except that algae dewaterer outer casing bottom.
The micropore sucker is formed by the dish type framework with along the some fan-shaped micropore disc that circumferentially is embedded on the framework, and each fan-shaped micropore disc is communicated with the central shaft axial passage by radial passage.
Algae water after the flocculation reaction enters algae-laden water separating and dehydrating machine, when water is completely near central shaft, the micropore sucker rotates under driven by motor, at this moment, under the effect of vavuum pump, underwater algae water filters through the micropore sucker, and blue-green algae is left on outside the micropore sucker, water then in micropore is inhaled into sucker, is discharged from algae-laden water separating and dehydrating machine through the runner of central shaft inside and the vacuum bothrium on the vacuum blowback dish more successively; And the blue-green algae that part remains in the micropore chuck surface rotates to waterline when above at sucker, is externally blown off under the compressed air blowback effect that source of the gas produces.For the blue-green algae mud that on sucker, can't blow off, the present invention also is fixed with scraper on the algae-laden water separating and dehydrating machine shell, blade surface and micropore sucker contacts side surfaces, when the micropore sucker rotates, the blue-green algae mud that adheres to is scraped by scraper, gets the pack outward transport by the screw rod sludge pump under the blue-green algae mud of blowing down and scraping.
Because the centrifugal dehydrator principle that algae-laden water separating and dehydrating machine of the present invention and prior art are used is different, it need not to adopt the high-power and high-speed motor, not only dwindled volume, and reduced electricity needs, improved the flexibility that device uses greatly, satisfied the requirement of vehicle-mounted or boat-carrying equipment volume, weight and power consumption.
