Topic.
In summary, in the prior art for improve shallow-layer dissolved gas floatator performance and it is cost-effective the problem of, still lack
Effective solution.
Utility model content
For overcome the deficiencies in the prior art, the utility model provides a kind of shallow-layer dissolved gas floatator, eliminates air
Compressor, it has, and energy consumption is low, noise is small, efficiency high, cost are low and is easy to the effect of maintenance.
The utility model uses following technical proposals：
A kind of shallow-layer dissolved gas floatator, including air dissolving system, release, water-locator and flotation tank, described air dissolving system
It is connected by release with the water-locator in flotation tank；Described air dissolving system includes water pump, the ejector being sequentially connected
And Gas dissolving pipe.
Further, three apertures of described release connect with Gas dissolving pipe, raw water water inlet pipe and water-locator respectively.
Further, described release is connected by pipeline with water-locator.
Further, the air inlet of described ejector is provided with check valve.
Further, outlet pipe is provided with described flotation tank, the water after processing is discharged or entered next by outlet pipe
Link.
Further, described air dissolving system and flotation tank are supported by support respectively, and described air dissolving system is located at air supporting
The side in pond.
Further, the bearing height of described flotation tank is higher than air dissolving system.
Compared with prior art, the beneficial effects of the utility model are：
(1) the utility model eliminates air compressor, overcome the high energy consumption brought with air compressor, noise it is big,
The problems such as investment is higher, maintenance is complicated；
(2) air dissolving system of the present utility model is the self-priming mode air inlet of unpowered supply, have energy consumption is low, efficiency high,
The low effect of cost.

Side.
The bearing height of described flotation tank 10 is higher than air dissolving system.
The course of work of the application is：
First, sewage is pumped into ejector 2 by water pump 1 with higher speed, and negative pressure, jet are formed in ejector 2
Device 2 sucks extraneous gas in water jets from air inlet 4 by check valve 3.
Then, water jets enter in the Gas dissolving pipe 5 of certain pressure, and in Gas dissolving pipe 5 under pressure effect, gas is with molecularity
State is dissolved in the water, and forms dissolved air water, after the decompression release of release 7, the gas molecule dissolved in water is gathered into dissolved air water
Tens nanometers to hundreds of nanometers big micro-bubbles, enter gas after being mixed with the raw water entered from raw water water inlet pipe 6 by pipeline 8
