Description
Technical field
The present invention relates to a kind of over-saturation for sewage disposal, environment water reparation and aquaculture oxygen supplement dissolve
Oxygen aerator, belongs to field of environment protection equipment.
Background technology
Aeration, during sewage disposal, especially biochemical treatment, is one of most crucial technique.Watercourse aeration is the most also
It it is the premise repairing the various water bodies such as city black-odor riverway, eutrophic lake, reservoir, estuary coast.China's aquaculture face
Long-pending wide, there is the water surface of millions of hectares, the dissolved oxygen demand of aquaculture is the biggest.For increasing aquaculture production, it is ensured that
Quality, needs efficient aeration aerating technology.Common aerator uses air aeration, as mechanical aeration and blast aeration fill
Put.Either mechanical aeration or blast aeration, oxygen dissolved efficiency is relatively low, the most only about 15-25%.This is due to sky
Oxygen content only about 21% in gas, the saturation solubility at 20 DEG C of clear water oxygens only has 9.1 mg/L.Use pure oxygen aeration, root
According to Henry's law, owing to oxygen partial pressure increases, dissolved oxygen concentration increases, the dense increase of saturated dissolving in water, at room temperature up to
43.3 mg/L.If continuing to increase oxygen partial pressure in aerator, during such as 2 air pressure, saturated dissolved oxygen concentration is up to 86.6
mg/L.Due to pure oxygen, to prepare expense more expensive, if using common microporous aeration device, partial oxidation can be caused to escape from water body
In air, cause waste, reduce pure oxygen aeration efficiency.Primary bright downflow system bubble contact aerator (U.S. Patent number
US3804255), also referred to as Speece taper oxygen-increasing device, use oxygen as source of the gas, almost 100% can utilize pure oxygen.Its
Principle is: by water pump, current being injected a turbination contact chamber from top to bottom, inverted cone contact chamber top has a pure oxygen to enter
Trachea, oxygen and high-velocity flow are mixed to form a large amount of bubble and flow downward with current.Flow downward process at gas-liquid mixture
In, owing to contact chamber cross-sectional area gradually expands, water velocity constantly reduces, when current decrease speed is less than bobble rise velocity
Time, oxygen bubble no longer flows downward, and such oxygen just can be " entrapped " inside cone.This device adds oxygen and current
Time of contact, oxygen utilization efficiency is up to 100% in theory.But this device has a following defect:
(1) water flow of this aerator and oxygen flow must maintain certain poised state, otherwise can cause oxygen gas
Steep and can not reach saturated dissolved oxygen concentration in the accumulation of contact chamber top or water outlet.In actual motion, current and air-flow are in time
Can fluctuate, both are extremely difficult to balance.Such as: needed for oxygen flow is more than water body during saturated dissolved oxygen amount, gas is risen
Bubble will build up in conical contact ceiling portion, form gas cavity, reduce water body and bubble contact strength and time, notably squeeze
Press contacts indoor water level, " squeezes bubble " and goes out reactor.If the amount of oxygen that oxygen flow can dissolve less than current, then water outlet
Dissolved oxygen concentration is less than saturated concentration, and aeration efficiency reduces.It is therefore desirable to oxygen flow and discharge are accurately controlled,
The two is made to keep dynamic equilibrium；
(2) though this device can guarantee that the oxygen time of staying within reactor, but the time of staying of current is limited.According to gas
Body is theoretical at the double membrane mass transfer of liquid diffusion, and oxygen dissolution depends on the mass transfer velocity in liquid film.Due to from top to bottom cone water
Flow Velocity constantly reduces, and is gradually laminar flow from turbulence transition, and between air-liquid, disturbance is not enough, and be so unfavorable between gas-liquid is fast
Speed mass transfer.

Meter.Horizontal tube at top cross over pipe connects emptying valve.Base diameter outlet connects outlet pipe.Through outlet pipe, current enter
Environment water.Controller passes through holding wire, and one end is connected with liquidometer, and the other end is connected with air intake control valve.Enter at current
Before conical contact room, the preposition of increase installs venturi air and liquid mixer and serpentine pipe blender exactly additional.
Venturi can be rapidly introduced into oxygen, under high-velocity flow, forms a large amount of microbubble in current, these microbubble water
Stream mixture enters back into serpentine pipe, and the centrifugal force and the shearing force that are produced by flow at high speed in serpentine pipe make current fill with bubble
Tap touches mixing, it is achieved the high-efficiency dissolution of oxygen.For reaching air-liquid flow equilibrium, increase cross over pipe in conical contact ceiling portion.By
Cavity will be formed in conical contact ceiling portion in superfluous oxygen, affect height of liquid level.By the liquid level in detection cross over pipe
