Description
Technical field
The present invention relates to field of sewage treatment equipment, particularly to the complete molten air-flotation system of one.
Background technology
Air-flotation system be a kind of remove in various industry and sanitary sewage fibre suspension, glue
The device of all kinds of impurity such as thing and oils and fats, it can manage to produce a large amount of bubble in sewage, is formed
Water, gas and by deimpurity three-phase mixture, can effectively adhere to all kinds of in the floating-upward process of bubble
Molecule, owing to adherend density emerges less than water density, thus reaches solid-liquid and divides
From purpose, this device is mainly used in chemical fibre, papermaking, pharmacy, refines oil, the industry work such as butchers
The purified treatment of industry sewage.Air floatation machine on the market is divided into two kinds by molten gas mode: turbine air supporting
Machine and dissolved gas floatator, turbine air floatation machine uses turbine aerator " microbubble " to be directly injected into
Without carrying out molten gas in advance in sewage, then by scattered gas impeller, " microbubble " is uniform
Be distributed in sewage, so whole service process will not occur choking phenomenon, but turbine air supporting
Machine equipment complexity, maintaining are costly；Dissolved gas floatator by air compressor machine and force (forcing) pump by air
Stream and liquid stream inject dissolving, deliver to flotation tank after fusing, due to fused flowing pressure poor stability,
Turbulent phenomenon easily occur, the bubble diameter of release is bigger and uneven, has a strong impact on daf efficiency.
Summary of the invention
For overcoming the deficiencies in the prior art, it is an object of the invention to provide a kind of simple in construction,
Being not easily blocked, separation efficiency is high, service life length complete molten air-flotation system.
The present invention is achieved through the following technical solutions: a kind of complete molten air-flotation system, including air supporting
Pond, force (forcing) pump and pressure air-dissolving tank, described force (forcing) pump is connected by soil pipe and pressure air-dissolving tank,
Before described force (forcing) pump, soil pipe is provided with medicament and adds entrance, and described soil pipe is provided with air release
Device, is provided with packing layer in described pressure air-dissolving tank, described pressure air-dissolving tank passes through molten gas soil pipe
Connecting with flotation tank, the top of described flotation tank is provided with Slag Scraping Device, the lower right of described Slag Scraping Device
Being provided with scum trough, the bottom of described flotation tank is provided with water collector, and one end of described water collector is from dirt
Water pipe and flotation tank connect distance is flotation tank length the 1/5 of end wall, described water collector
The other end connects clear water pipe.
Preferably, the top of described pressure air-dissolving tank is provided with vent valve, described pressure air-dissolving tank
Top is provided with Pressure gauge.
Preferably, described molten gas soil pipe is provided with air relief valve.
Preferably, described flotation tank is carbon steel or stainless steel cuboid flotation tank.
The invention has the beneficial effects as follows: fused flowing pressure can be control effectively by the present invention, carries
High pneumatically supported stability and separation efficiency, and simple in construction, be not easily blocked, and service life is long.

Detailed description of the invention
The complete molten air-flotation system of one as shown in Figure 1, including flotation tank 6, force (forcing) pump 2 and pressure
Power dissolving 4, described force (forcing) pump 2 is connected by soil pipe 11 and pressure air-dissolving tank 4, institute
Before stating force (forcing) pump 2, soil pipe 11 is provided with medicament and adds entrance 12, described soil pipe 11 sets
There is air release 3, described pressure air-dissolving tank 4 is provided with packing layer 13, described pressure air-dissolving
Tank 4 is connected by molten gas soil pipe 11 and flotation tank 6, and the top of described flotation tank 6 is provided with
Slag Scraping Device 8, the lower right of described Slag Scraping Device 8 is provided with scum trough 10, the end of described flotation tank 6
Portion is provided with water collector 9, and one end of described water collector 9 connects from soil pipe 11 and flotation tank 6
The distance of end wall is the 1/5 of flotation tank 6 length, and the other end of described water collector 9 connects to be had clearly
Water pipe 14, the top of described pressure air-dissolving tank 4 is provided with vent valve 7, described pressure air-dissolving tank 4
Top be provided with Pressure gauge 1, described molten gas soil pipe 11 is provided with air relief valve 5, described air supporting
Pond 6 is carbon steel or stainless steel cuboid flotation tank.
During use, utilize air release 3 and force (forcing) pump 2 air-flow and liquid stream to be injected pressure simultaneously
In power dissolving 4, fuse and flow by entering flotation tank 6 after air relief valve 5 and vent valve 7 voltage stabilizing,
Fused stream enters in flotation tank 6, and air soluble in water is upwards separated out by buoyancy, and in water
Impurity bonding, form the proportion adherend less than 1, owing to adherend density is less than watertight
Degree, so energy fast lifting is to the water surface, forms scum layer, and the floating scum silica frost come up, by scraping
Slag machine 8 circulates continual being scraped in scum trough 10, thus reaches the purpose of solid-liquid separation.
