Background technology
Mankind's activity increasingly sharpens on the impact of aquatic ecosystem, causes the amount reproduction metabolism of Measures of Algae in Water Body, causes water quality deterioration, and the structure and function of the ecosystem is destroyed.Meanwhile, algae can produce toxin, and the mankind and hydrocoles are brought to great harm, especially as lake, the serious threat of reservoir water body alga eruption of drinking water source, resident's drinking water safety.Conventional hydrocyclone separation technology device is being brought into play certain advantage aspect oil removing, desanding at present, but limited in one's ability for the removal of algae.
Device for sterilizing and removing alga > > in CN102262008A < < water sample pretreatment system, its structure is, two imports of the outlet of ozonizer ozone and scavenging pump water outlet pipeline connecting tee, the outlet of described threeway is connected with anti-cleaning valve, spray valve inlet pipeline respectively, described anti-cleaning valve outlet connects respectively the import of settling pit sampling valve and sampling conduit, and described spray valve outlet is connected with the spray header pipeline that is placed in sedimentation basin top.This apparatus structure complexity, carries out the sterilization algae removing of water sample by ozonizer and spray, can not guarantee except algae effect.
Summary of the invention
The problem existing for existing water body algae removal technology, the utility model provide a kind of easy to operate, energy consumption is low, except the effective water body algae-removing device of algae.This device has increased water sprayer gas injection system on the basis of common waterpower cyclone separation device, air supporting flotation technology and cyclone separation process is combined, thereby realize the separation of algae and water body, to reach the object except algae.
Water body algae-removing device of the present utility model, the concrete technical scheme of employing is as follows:
This algae-removing device, comprise the water lift pipe, algae strainer, tube mixer, lift pump, water sprayer and the hydrocyclone that are connected in turn, on water lift pipe, be provided with algae strainer, tube mixer is provided with dosing mouth, this dosing mouth is connected with chemicals dosing plant, water sprayer is provided with airway, and hydrocyclone top is provided with taper overflow port, and bottom is provided with underflow opening;
Containing the former water of algae, by water lift pipe, enter algae strainer, part algae and the barred of solid impurity particle, the water after filtration enters tube mixer; By chemicals dosing plant, to tube mixer dosing mouth, add permanganate composite chemical and flocculation agent, permanganate composite chemical dosage is 0.5-1.5mg/L, and flocculation agent adopts polymerize aluminum chloride (PAC), and dosage is 10-30 mg/L; In tube mixer, medicament and water body fully mix, and permanganate composite chemical is to former water preoxidation, to improve except algae efficiency, reduce the algae substances content in water outlet, meanwhile, part algae substances forms macrobead flco with the colloidal particle in former water and suspended particulate; Former water after dosing promotes and enters water sprayer through lift pump, and air injects water body by the airway on water sprayer, forms gas liquid mixture; Gas liquid mixture enters hydrocyclone, in hydrocyclone, gas is by discharging in water body, microbubble carries algae substances and is overflowed by the taper overflow port at hydrocyclone top, solid macrobead is flowed out by the underflow opening of hydrocyclone bottom with water outlet, realizes the separation of algae substances and water body.
The utility model is by air supporting flotation and the effective combination of cyclonic separation, and hydrocyclone top adopts the water outlet of taper overflow port (to increase overflow port place volume, reduce the center pressure of cyclone separator, be conducive to gas discharges from water body, thereby realize gas-liquid separation, improve the separating effect of algae substances and water body), further improved separation efficiency, have easy to operate, energy consumption is low, except the high advantage of algae efficiency, be particularly useful for the easy outburst of algae and lower lake, the reservoir water of turbidity to remove algae pre-treatment.
Accompanying drawing explanation
Fig. 1 is the structural principle schematic diagram of the utility model water body algae-removing device.
In figure: 1, containing the former water of algae, 2, water lift pipe, 3, algae strainer, 4, chemicals dosing plant, 5, tube mixer, 6, lift pump, 7, water sprayer, 8, airway, 9, air, 10, hydrocyclone, 11, taper overflow port, 12, algae substances, 13, underflow opening, 14, water outlet.
Embodiment
As shown in Figure 1, algae-removing device of the present utility model, is mainly comprised of water lift pipe 2, algae strainer 3, chemicals dosing plant 4, tube mixer 5, lift pump 6, water sprayer 7 and hydrocyclone 10.Water lift pipe 2, algae strainer 3, tube mixer 5, lift pump 6, water sprayer 7 and hydrocyclone 10 are connected in turn.Algae strainer 3 is existing installation, and one end is water-in, and one end is water outlet, and inside is provided with filter basket, and bottom is provided with sewage draining exit, when needs clean, opens the cock on filter bottom sewage draining exit, and the impurity such as algae are discharged by sewage draining exit.Tube mixer 5 is connected with chemicals dosing plant 4 by the dosing mouth on it, and a side of water sprayer 7 is provided with airway 8, and the top of hydrocyclone 10 is provided with taper overflow port 11, and bottom is provided with underflow opening 13.Chemicals dosing plant 4 comprises medicine-adding bin and volume pump, and volume pump is connected with the dosing mouth on medicine-adding bin and tube mixer 5.
When in lake, reservoir containing the former water 1 of algae when water lift pipe 2 enters algae strainer 3, part algae in former water, solid impurity particle are blocked in outside the filter basket of algae filter interior, and filter after water by filter outlet, discharge, water outlet enters tube mixer 5.By chemicals dosing plant 2, to tube mixer dosing mouth, add permanganate composite chemical and flocculation agent.According to raw water quality difference, permanganate composite chemical dosage is 0.5-1.5 mg/L, and flocculation agent adopts polymerize aluminum chloride (PAC), and dosage is 10-30 mg/L; In tube mixer 5, medicament and water body fully mix.Permanganate composite chemical preoxidation can significantly improve except algae efficiency, thereby reduces the algae substances content in water outlet, and meanwhile, part algae substances forms macrobead flco with the colloidal particle in former water and suspended particulate.Former water after dosing promotes and enters water sprayer 7 through lift pump 6.In the airway 8 of air 9 from water sprayer 7, inject water body, form gas liquid mixture.Gas liquid mixture enters hydrocyclone 10, at the interior gas of hydrocyclone 10, discharge in by water body, microbubble carries algae substances 12 and is overflowed by the taper overflow port 11 at hydrocyclone 10 tops, solid macrobead is flowed out by the underflow opening 13 of hydrocyclone 10 bottoms with water outlet 14, realizes the separation of algae substances 12 and water body.
