Abstract

The utility model relates to a wind energy surface aerator for sewage treatment, which comprises mainly a fixed platform, buoys, a rotary shaft, a wind wheel, an impeller, a casing and a fixed cross beam. The external shape of the utility model is a barrel body structure, and the bottom part is installed on the fixed platform; a plurality of buoys is arranged on the corners of the fixed platform. Two arc-shaped curved wind wheels which are installed on a center vertical moving shaft of the utility model are rotated around the center vertical moving shaft. Underwater, the center vertical moving shaft is provided with the screw impeller; the external part of the barrel body is the stainless steel casing, and the fixed cross beam is installed on the top part of the stainless steel casing.

Description

Waste water control wind energy top layer aerating apparatus

The utility model relates to a kind of aerating apparatus, particularly a kind of waste water control wind energy top layer aerating apparatus belongs to river sewage and administers the field.

City a large amount of sanitary sewage, trade effluents every day, because in time do not administer, these dirty contaminated wastewaters the river course and the environment in city, are having a strong impact on city resident's life, severe contamination is regional even endanger vegeto-animal life and human living condition, has destroyed the eubiosis.In the big lake of China near the city, as Kunming Dianchi lake, Chaohu, Hefei etc., in the nitrogen in input lake, the phosphorus total load, have 50% approximately from municipal effluent, 50% from basin non-point source rainwash and lake region precipitation, far away from the city or be subjected to urban industry waste water, sanitary sewage discharging to influence less lake, reservoir, as Gaozhou county reservoir, Dianshan Lake, Nansi Lake etc., the nutrition load is mainly from the pollution of area source of lake drainage, and its nitrogen, phosphorus load account for the 60-70% into the lake total load.Therefore administering river course, lake eutrophication in the waste water control is an important step.Utilize wind energy directly to be the existing very long history of human service, be to utilize wind-power electricity generation mostly, also utilize the wind driver tool, as mill, water storage etc., utilize the equipment that wind-force is half congealed at Xiao Chi, fishpond shines water as ventilation in addition, through the document Investigation retrieval, still do not have so far about utilizing wind energy to administer the bibliographical information of river course, lake sewage.

The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of river sewage to administer wind energy top layer aerating apparatus.

The technical solution of the utility model is as follows: mainly comprise: stationary platform, floating drum, rotation axis, wind wheel, impeller, outer cover and fixed cross beam, its profile is a tube structure, the bottom is installed on the stationary platform, some floating drums are installed on the angle of stationary platform, the wind wheel that two arc-shaped bends are installed on its central vertical moving axis sways, Z-axis is equipped with helical runner under water, and the cylindrical shell outside is the stainless steel outer cover, and the top is equipped with fixed cross beam.

During the utility model actual motion, on the water surface,, on the water surface, keep balance by the effect of floating drum and stationary platform.

Pass through on the thin plate of wind by bending, produce torque by the pressure reduction between the male and fomale(M﹠F) of luvside, the backflow on convex surface also produces torque, begins to rotate at these two moment loading lower devices.The startup wind speed 1.6m/s of device, after wind speed reached the startup wind speed, wind wheel rotated, and promoted the rotation of central shaft, drove the underwater wheel rotation, stirred water body, carried out surface aeration.During aeration, impeller stirs surface water, makes the water body top layer produce hydraulic jump, macro-mixing liquid water droplet and membranaceous water are got rid of in air, carry the air-water mixture of air formation then and get back in the water, the aqueous vapor contact area is big more, and airborne oxygen is easier dissolving in the water just.Along with the moving wind wheel of continuous wind, drive rotation axis and impeller and constantly rotate, surface water is brought in constant renewal in, and oxygen constantly dissolves in, and the mixed solution that content is little in the lower layer of water is under the impeller stirring action simultaneously, and circulation makes progress; The downward circulation of mixed solution that top layer oxygenation zone oxygen level is many, the different water layer of dissolved oxygen concentration exchanges up and down, thereby has improved the dissolved oxygen content of water body, makes the dissolved oxygen levels of each layer water body under the top layer that in various degree raising be arranged.

The utlity model has technical novelty and creativeness, and have wide practical value, in carrying out the oxygenic aeration process, need not any power, can carry out the top layer aeration, can held stationary work at the following of the general stormy waves in the external world.In minimum work wind speed is under the 1.6m/s condition, and accepting wind energy is that power is worked, and mixes the levels water body, thereby improves the dissolved oxygen of water body.The purification of water quality that is suitable for great water bodies such as river, lake, reservoir, and the improvement of all kinds of point-source pollutions.

Below in conjunction with accompanying drawing the utility model is further described:
