Abstract
The utility model relates to a perforating dispersed flow aerator, particularly oxygen inflating equipment used for the biochemical sewage treatment. The utility model is composed of an air inlet pipe, a sawtooth air distributing head and a dispersed stream cover. The utility model is characterized in that a perforated board is arranged on the air inlet pipe. A bundling air bubble which is sent to the water by the air inlet pipe is firstly broken through the perforated board forcibly, which is beneficial to form uniform air bubbles with smaller diameters to efficiently improve the use ratio of oxygen and meliorate oxygenated performance. The use ratio of oxygen of the utility model is higher than that of the general big or medium-sized bubble aeration equipment; the perforating dispersed flow aerator has the advantages of simple structure, convenient installation and maintenance and lower cost. Because the utility model is made of glass fibre reinforced plastic, the utility model has wide appliance region and long service life.
Description
The utility model relates to essential oxygen replenishing equipment in a kind of sewage biochemical treatment.
Air diffusion aerator has oxygenation capacity preferably with it, is regarded as domestic comparatively ideal aerator at present.Application number is 89216595.2 Chinese patent " dicyclo umbrella shape aerator ", mainly be on the architecture basics of former air diffusion aerator, set up a circular saw air distribution head, this aerator has certain improvement than the former oxygenation capacity, but it is not obvious, and because it has set up a ring and a umbellule cover, the structure more complicated has also improved manufacturing cost.In addition, above-mentioned aerator is all made with polyvinyl chloride, and shock resistance is poor, and easily aging distortion, influences work-ing life.
The purpose of this utility model provides a kind of perforation air diffusion aerator that better oxygenation capacity, simple structure, cost are lower, work-ing life is long that has.
The utility model is so to realize: aerator is made up of inlet pipe, sawtooth air distribution head and the stream cover that looses, and it is characterized in that being equipped with on intake ducting a perforation plate.Aerator adopts glass reinforced plastic to make.
The utility model is owing to installed a perforation plate on intake ducting, make the boundling bubble of sending into water liquid by inlet pipe, at first after perforation plate is forced fragmentation, in diffusion and uphill process, again through sawtooth air distribution head and the diffusing continuous multi-stage cutting and crushing that flows the cover sawtooth, simultaneously, impounded body water liter around numerous bubbles entrain, because difference in specific gravity has been strengthened the blending effect of bubble breaking and gas-liquid, quickened the renewal of liquid-gas interface moisture film, increase the contact area of gas-liquid, thereby improved the utilization ratio (making the utilization ratio of oxygen be higher than bubble aeration equipment in general big one) of oxygen effectively, improved the oxygenation capacity of aerator.In addition, the utility model simple structure, installation and maintenance are all more convenient, and cost is lower, because adopt glass reinforced plastic shock-resistant, ageing-resistant, that water resisting property is good to make, makes it have long work-ing life.
Structure of the present utility model is by following embodiment and description of drawings thereof.
Fig. 1 is the device synoptic diagram of perforation air diffusion aerator.
As shown in Figure 1, the perforation air diffusion aerator is made up of inlet pipe (1), perforation plate (2), sawtooth air distribution head (3) and the stream cover (4) that looses, and perforation plate (2) is installed in the appropriate location of intake ducting such as the inner lower of sawtooth air distribution head (3).Above-mentioned parts adopt glass reinforced plastic to make, and can be widely used in all kinds of sewage disposals under south, the northern high/low temperature condition.The height overall of aerator is 235mm.The stream cover (4) that looses is the device of falling the umbrella shape, and diameter is φ 600mm, high 70mm, its peripheral even 102 sawtooth that have a down dip slightly that are furnished with.Perforation plate (2) diameter is φ 112mm, and it is 81 of the apertures of φ 3.1mm that diameter is arranged on the perforation plate.The high 95mm of sawtooth air distribution head (3), following end periphery is even to be furnished with 24 sawtooth.
The now oxygenation capacity contrast with the utility model and other three kinds big-middle air bubble aerators is listed as follows:
Condition of work: depth of water H=4.5m
Air quantity Q=30m
3/ h
Claims (2)
1, a kind of perforation air diffusion aerator is made up of inlet pipe [1], sawtooth air distribution head [3] and the stream cover [4] that looses, and it is characterized in that being equipped with on intake ducting a perforation plate [2].
2, aerator according to claim 1 is characterized in that aerator adopts glass reinforced plastic to make.
