Description

A kind of new-type oxygen-increasing device

Technical field

The invention belongs to environment-protective water processing technology field, be mainly used in the water reoxygenation of the surface water such as lake, river, reservoir, pond, landscape water body.

Background technology

The surface water such as the river of China, lake, reservoir, pond mostly also exist serious pollution.After substantial amounts of undressed trade effluent, sanitary sewage, agricultural irrigation, water is directly discharged into river, river, lake, sea, causes the frequent generation of water pollution and eutrophication.Pollutant are bigger than water due to proportion, mostly fall to the bottom, and substantial amounts of contaminant degradation has exceeded the self-purification capacity of water body, consume the oxygen of bottom water body, make bottom water body be chronically at anaerobic condition.Dissolved oxygen is not enough, and anaerobic digestion produces foul smell and black liquor, causes water body blackout smelly.Simultaneously because bottom water hypoxia, promote the release of phosphorus in bed mud, further increase the probability that wawter bloom occurs.

Physicochemical philosophy------is thought by Henry's law: under isothermal and isobaric, and certain gas dissolubility in the solution is directly proportional to the balance pressure of this gas on liquid level.Utilize forced air to carry out water oxygenation and be applied (such as jet oxygen-increasing machine) the most in practice, but the OTR of jet oxygen-increasing machine is relatively low, 35% only up to be reached, but Jet-flow oxygen increasing can only be local oxygen enriching, it not comprehensive oxygen supplement, bottom is risen influence on water body little simultaneously, undesirable to the oxygenation effect of profundal zone.

The invention provides a kind of to carry out circulating water flow by forced air, make water body oxygen promote rapidly quickly to the device of a large amount of water oxygenations, simultaneously also can give bottom water oxygenation.

Summary of the invention

1. the invention provides a kind of can be to big water oxygenation, can the device of flexible adaptation different depth water body, this device includes: taper device, water pump, be placed in pressurized gas source generator on the bank, agitator, auxiliary aeration tube, gas evacuated tube, and connecting tube composition, water is pumped into taper device by water pump, gas is also pumped into taper device by pressurized gas source, water is sufficiently mixed by agitator with gas, the fully air-water mixture after oxygen supplement enters auxiliary aeration tube auxiliary aeration from taper device, being then discharged out outside device, unnecessary gas is discharged from gas evacuated tube.

In said apparatus, the truncated cone that taper device is truncated as top, current enter cone from top, the outlet from lower end of the air-water mixture after oxygen supplement is flowed out, lower end outlet can be one or more, can be rustless steel for making the material of taper device, it is also possible to be fiberglass, can also is that alumal equal strength is big, corrosion-resistant material.

In said apparatus, the gas of input cone can be air, it is also possible to is pure oxygen, or air and the mixed gas of pure oxygen, and the gas of input cone should grant certain pressure.

In said apparatus, can be pumped into by water pump from the water source through entering, the taper device top, it is also possible to allow water flow freely in bullet by hydraulic gradient, form unpowered device, save the energy.

In said apparatus, pressurized gas source preferably should be placed in middle part or the bottom of taper device, to increase sinking water body and the time of contact of gas-pressurized rising, simultaneously, water body is during sinking, at the top of taper device, the speed that water velocity rises more than bubble, prevent bubble to overflow from taper device top, and in the bottom of taper device, water velocity constantly expands due to taper device bottom surface, and speed reduces, and bobble rise velocity is very fast, can constantly rise, gas is sufficiently mixed with water body, adds the exchange of oxygen and water, thus gives water oxygenation.

In said apparatus, due to continually entering of gas-pressurized, unemployed gas is by by outside the gas outlet pipe discharger that taper device exports, and the gas liberation port of gas outlet pipe is positioned on the water surface.

In said apparatus, agitator (impeller) can be located in bullet, it is possible to is positioned at bullet and the junction of auxiliary aeration tube, to promote current, and makes water body and gas be sufficiently mixed.

In said apparatus, auxiliary aeration tube being provided with microporous aeration disc, the available device of gas-pressurized that produces is to microporous aeration disc aeration, and with further as water oxygenation, micro-pore aeration is proved the mode into a kind of effective bottom oxygen supplement.

In said apparatus, as used motorless hydraulic gradient water intake mode, the upper opening of taper device can arrange guard, to prevent foreign material in water from entering device.

In said apparatus, gas-pressurized, before entering device, can install manostat additional, the oxygenation effect stable to increase whole device.

In said apparatus, auxiliary aeration tube outlet can on water body top layer, can also be in water body middle level, it is also possible at water bottom, think the water oxygenation of different levels.

Compared with prior art, the invention has the beneficial effects as follows:

1. oxygen-enriching: the present invention uses gas-pressurized and speed gradually to delay water oxygenation, can give and set water body oxygen supplement rapid, a large amount of, improve the state of water hypoxia, accelerate organic matter decomposition, reduce the generation of water body poisonous and harmful substances.

The most comprehensive customization oxygen supplement: the immersible pump of the present invention, compressor horsepower, the height of auxiliary aeration tube, all can self assemble as required, can be the water body of different depth, water body that surface area is bigger, carry out customization oxygen supplement respectively, solve tradition can only local oxygen enriching, or the deficiency of surface oxygen supplement.

3. reduce thrashing: the foreign material in water are separated with water inlet by present invention metal cap net, decrease owing to the impurity in water enters taper device, cause the damage of device.

The most with low cost: the taper device of the present invention, aqueduct, support member all use common rustless steel, fiberglass, the engineering plastics such as ABS, PVC, PPR, immersible pump all can be purchased from the market, it is easy to batch production, and cost is low, whole system is the most perishable, it is simple to clean.

5. management is safeguarded simple: the taper device of the present invention, water jet delivery tubes, immersible pump, agitator, micro-pore oxygenation dish are the most disassembled, if any damaging readily replaceable and maintenance.
