Abstract
The invention relates to an algae removal device for a water body. The device comprises a water lifting tube, an algae filter, a tubular mixer, a lifting pump, a water injector and a hydrocyclone separator sequentially connected. The tubular mixer is provided with a dosing opening which is connected with a dosing device, the water injector is provided with a gas-guide tube, a cone-shaped overflow port is arranged at the top of the hydrocyclone separator, and a bottom flow port is arranged at the bottom of the hydrocyclone separator. Part of algae and solid impurity particles in raw water are removed by the algae filter. The dosing device casts a permanganate complex reagent and a flocculant into the tubular mixer, so that the reagent is fully mixed with the water body. The dosed raw water enters into the water injector to form a gas-liquid mixture in the water injector. The gas-liquid mixture enters into the hydrocyclone separator to separate algae matters and the water body. The device provided by the invention effectively combines gas flotation and hydrocyclone separation, and the cone-shaped overflow port is arranged at the top of the hydrocyclone separator, so that the separation efficiency is further improved. The device has the advantages of convenience in operation, low energy consumption and high algae removal efficiency.

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 is complicated, 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 invention provides 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 separated of algae and water body, to reach the object except algae.
Water body algae-removing device of the present invention, 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, at gas in hydrocyclone, in water body, discharge, microbubble carries algae substances and is overflowed by the taper overflow port at hydrocyclone top, with water outlet, the underflow opening by hydrocyclone bottom flows out solid macrobead, realizes the separated of algae substances and water body.
The present invention 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.
