Description
Technical field
The utility model belongs to environment friendly water body purification techniques and deodorization technology field, is related to a kind of floated micro-nano aeration
Device.
Background technology
Aerator in present sewage disposal plant aeration tank is to use to install air blower outside pond, passes through aeration tank bottom
Gas distribution pipeline and micro porous aeration head to sewage mixed liquor be aerated, due to aeration head pore size be 1~3mm, so aeration
The bubble diameter of generation is also between 1~3mm, and the depth of water in aeration tank is generally 4~6 meters, and bubble by transporting bottom-up
During the dynamic through water surface, the oxygen in bubble is transferred in water, and the microorganism survived into water provides oxygen, it is ensured that microorganism
Activity.
But this method is not very high due to the oxygen transfer efficiency of bubble, so in design selection, required air blast
Machine power load is big.The operating cost of one sewage plant is mainly the electricity charge, labour cost and medicament expense, if so can improve bubble
Oxygen transfer efficiency, reduction power load reduces the electricity charge, then can save huge operating cost to sewage plant, is the energy-conservation of country
Emission reduction contributes.
The content of the invention
The problem of the utility model is namely based on the above, proposes to use micro-nano aeration process, by immersible pump and micro-nano
Injector is positioned in frame body, is suspended in the sewage of aeration tank, this kind of structure design and the peace being suspended in the sewage of aeration tank
Holding position can play the efficiency of micro-nano injector to greatest extent.Injector can spray micron order and nano level bubble, by
Small in bubble diameter, micron-sized bubble is slow in underwater exercise, and the oxygen in bubble has time enough to be transferred in water, simultaneously
Nano level bubble is moved downward and soluble in water in water body, therefore the oxygen transfer rate in bubble is high.Due to having in water body
Enough dissolved oxygens, the activity increase of microorganism, substantially increase the ability and speed of pollutant in degraded water body, obtain water body
To purification, simultaneously because dissolved oxygen is high, aerobic bacteria amount reproduction suppresses anaerobic bacteria existence, therefore the stink of water body can be eliminated,
The yield of sludge is reduced simultaneously, and water bottom sludge can also be reduced therewith, reach the purpose of purifying water body.Thus one brought
Individual most important result is due to that oxygen transfer rate is improved, and in the case where handling same water, selected device installed capacity is low, than choosing
The installed capacity for selecting conventional fan is low by more than 50%.
The purpose of this utility model is to provide a kind of floated micro-nano aeration device for being conducive to improving oxygen transfer rate, tool
Body technique scheme is as follows.
The floated micro-nano aeration device of a kind of water body purification, it is characterised in that including frame body, installed in frame body
The pump device connecting tube of the immersible pump of bottom and the injector installed in frame body top, connection immersible pump and injector, with injection
The air duct of device air inlet connection, the floating drum being connected with frame body.Pressurizeed by immersible pump, under the action of the centrifugal in injector
Portion forms negative pressuren zone, and air enters negative pressuren zone by air duct, uniformly cut into micro-nano bubble；Floating drum can make aeration
Device is suspended in the sewage of water body or aeration tank, is taken full advantage of the oxygen in micro-nano bubble, is improved oxygen transfer rate.
Further, frame body is provided with screen pack, prevents debris from entering immersible pump.
Further, floating drum is inflatable floating drum, can suitably select floating drum quantity to make exposure according to the weight of aerator
Device of air is just suspended in water body.
Further, the front end of injector is provided with deflector, can move downward the air-flow point part ejected, by pump
Debris on the screen pack of body surrounding is washed out, and reduces the resistance of screen pack.
Further, air duct top is provided with air cleaner, prevents the debris in air from entering injector.
Further, it has been provided with and has withheld at the top of frame body, has facilitated equipment to install.
The floated micro-nano aeration device of a kind of water body purification that the utility model is provided, with simple in construction, installation
Convenient, Dissolved Oxygen in Water is high, the advantage of obvious energy conservation.
