Description

A kind of device for surface water bottom aeration oxygen replenishing

Technical field

The utility model belongs to environment-protective water processing technology field, is mainly used in the water oxygenation of the surface water such as lake, reservoir, pond, landscape water body.

Background technology

The river of China, lake, reservoir, the surface water such as pond mostly also exist serious pollution, a large amount of undressed industrial sewages, sanitary sewage, after agricultural irrigation, water directly enters river, river, lake, sea, cause the frequent generation of water pollution and eutrophication, pollutent due to proportion larger than water, mostly fall to the bottom, a large amount of contaminant degradations has exceeded the self-purification capacity of water body, consume the oxygen of bottom water body, bottom water body is made to be in anoxic condition for a long time, dissolved oxygen is not enough, anaerobic digestion produces foul smell and black liquor, water body is caused to turn black smelly, simultaneously due to bottom water hypoxia, facilitate the release of phosphorus in bed mud, further increase the possibility that wawter bloom occurs.

Water-bed oxygenation contributes to thermal stratification and the chemical stratification of breaking lake; Contribute to promoting anoxic water body and replacing anoxic water body; Contribute to the phosphorus in binding and sedimentation water body, reduce the release of sedimentary phosphate; Contribute to the content reducing water body solvability iron, manganese, sulphur; Also contribute to improving fish and zoobenthos habitat, water-bed oxygenation efficiency, when other conditions are identical, is better than other surface aeration equipment greatly, as water wheel type aeration.

Chinese invention patent CN201238534 discloses a kind of water-bed aeration oxygen replenishing and specially puts, it utilizes roots blower air feed, pneumatic tube connects the air feed that multiple arm with micropore realizes pond bottom, but micropore arm is laid in the easy epiphytic algae of pond bottom and the invertebrates such as low, breed bacteria, blocking microporous.

Great majority close the shape of water body and irregular, in the inherent different azimuth of water body, different spaces, the amount of required oxygenation is also not quite similar, the oxygen requirement of such as contributing region just may be fewer than the oxygen requirement in fish collection district, the oxygen requirement of offshore water is relatively more less than the oxygen requirement of ballow, existing technical scheme effectively cannot adjust erection space, shape is fixed often, and processing area is also fixed.Use single oxygenation design, not only fully can not cover water body, meet the needs of local water oxygenation, may energy waste be increased simultaneously, and the supersaturation of the nitrogen of excessive local oxygen enriching generation can cause N stress and injury to fish and other hydrobionts.

Summary of the invention

In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides one flexibly, may be combined with, separate with bed mud appropriateness, adapt to different water body, the device of oxygenation aeration bottom the surface water of the different sites of same water body, it comprises: power supply, blower fan, air delivery pipe, micro-hole aerator, ventilation pipe support and support chassis, air delivery pipe one end is connected with the air outlet of blower fan, the other end is connected with check valve, check valve is connected on ventilation pipe support, one or more aeration head of aerator is connected with ventilation pipe support, then pipe support of ventilating is fixed in support chassis, the pressurized gas that the rear fan that switches on power produces passes through air delivery pipe, then check valve, then micro-hole aerator is entered, body of calming the anger is had to produce microbubble stream by the pore on micro-hole aerator.

In said apparatus, the micro porous aeration head of aerator can select tubular type, disc type or spherical cap type shape, this device is placed in the bottom at ordinary times, under non-ventilating state, because hydraulic pressure is greater than the internal gas pressure of this device, the micropore of aerator is closed, thus avoid water and pollutent enters aerator inside, during work, pressurized air enters aerator inner chamber from blower fan, aerator starts to expand, after internal pressure is greater than hydraulic pressure, aerating pore just can be opened, ensure that aerating pore aeration is even, simultaneously because micropore is very little, gas from solarization air cap out after, form minimum bubble, lift velocity is slow, the contact area of oxygen-containing gas and anoxic water body and duration of contact are increased greatly, add dissolved efficiency and the exchange efficiency of oxygen, add water body oxygen level, improve charging efficiency.

In said apparatus, the common materials of aeration head has EPDM(Ethylene Propylene Terpolymer) rubber, silica gel, white fused alumina, ceramic corundum, aeration stone, diamond, wherein with EPDM(Ethylene Propylene Terpolymer) rubber is best, other as corundum and aeration stone aeration head because pore may block, reduce ventilation efficiency, clean and maintenance at set intervals may be needed.

In said apparatus, ventilation pipe support and the square elbow connected, 3 siphunculus, 4 siphunculus, can adopt corrosion-resistant pvc pipe, PPR pipe.

In said apparatus, the hollow that support chassis material can adopt the engineering plastics such as PVC/PPR to make, the chassis cavity of hollow can load the weights such as sandstone, with stopple, chassis is closed, device is made to be easy to sink under the water, the bottom surface area that chassis contacts with Sediments should be larger, device is made steadily to be erected at above sediment layer, be unlikely to topple and poach, chassis also can be other shape support materials, if upholder also can be one piece of large flat board, aerating apparatus is separated with settlings such as bed muds.

In said apparatus, air delivery pipe can be PU tracheae, PVC hose, Self-sinking type rubber hose, steel wire rubber hose etc., be good with Self-sinking type rubber hose, other tracheaes need to fasten weight makes its submerged, air delivery pipe length can be followed according to needs adjustment, enables aerator reach the different sites of water body.

In said apparatus, the blower fan of air feed can be vane-type blower fan, also can be positive displacement blower fan, and blower fan should be the larger ventilator of aero operating pressure, gas blower, compressor etc., is beneficial to pressurized air to pump in device.

In said apparatus, the quantity of the aeration head of aerator can regulate as required, for small water, one to be placed in water body innermost, has the aerator of 4 aeration heads just can meet the demands, for great water body and Deep lake, a large amount of aeration heads may be needed just to complete covering to water field of big area, such as, design large reservoir bottom is aerobic, the rectangle aerator of 600 aeration heads altogether of 30 (length) × 20 (wide) may be needed just to satisfy the demand.

In said apparatus, aerator can be contacted mutually by connecting tube, or linearly arranges, and is connected with blower fan separately afterwards, is conducive to the abundant aeration to long and narrow water body such as river course.

In said apparatus, it is multiple aerator air feed that multiple-way valve can be installed in air compressor machine air outlet, for irregular water body, the mode that the multiple aerator of distributing can be adopted simultaneously to work is oxygen supply of water body, such as an irregular water body of approximate dumbbell shaped, an aerator can be respectively set at the water body of two of a dumbbell approximate hemisphere.

Compared with prior art, the beneficial effects of the utility model are:
