Embodiment
Below, preferred embodiment describe of the present invention with reference to accompanying drawing.In addition, in description of drawings,, omit repeat specification to identical important document additional phase symbol together.
Fig. 1 is the partial cut away side views of the diffusing inflator 5 of this embodiment, and Fig. 2 is the end view along the II-II line of Fig. 1.As shown in Figure 1, the device of air 1 that looses comprises and leads to fan and link and the air supply pipe 3 that extends to horizontal direction (the paper vertical direction of Fig. 1) and constitute to the diffusing inflator 5 that extends with the roughly orthogonal horizontal direction of the axis of this air supply pipe 3 (left and right directions of Fig. 1) to the standpipe (not shown) that above-below direction extends.The inflator 5 that should loose is disposed with a plurality of on the paper vertical direction with respect to air supply pipe 3.
Be formed with ventilating pit 3a on the linking part of air supply pipe 3 and diffusing inflator 5, air supply pipe 3 will be supplied in the inflator 5 that looses through ventilating pit 3a via the air that the standpipe air-supply is come.
The inflator 5 that looses has cylindric support tube 7, and has the diffusing air film 31 that forms urceolus.Air from air supply pipe 3 is directed in the gap 35 between support tube 7 and the diffusing air film 31 through above-mentioned ventilating pit 3a.
The air film 31 that looses is made up of the starting material that for example rubber etc. has retractility, looses in the air film 31, is formed with a plurality of diffusing gas slit S as air dispelling hole.
At this, the diffusing gas slit S that is formed at the air film 31 that looses is described.Fig. 3 is the stretch-out view of diffusing air film 31 of the diffusing inflator 5 of this embodiment.This stretch-out view illustrates from diffusing air film 31 of the following lateral incision of support tube 7 and unfolded appearance.
The gas slit S that looses goes up to reach at axis direction (diagram left and right directions) and is disposed with a plurality of around axis (diagram above-below direction).And; Form the gas slit S that looses according to following mode: on the optional position of axis direction; The summation that the summation of the arrangement of the vertical downside when loosing inflator 5 about on axis direction, arranging the summation of the port area of a plurality of diffusing gas slit S that is provided with, being provided with is arranged greater than its upside.
In other words; Form the gas slit S that looses according to following mode: imagination will be loose becomes the part of vertical upside when the part that becomes downside is carried out five equilibrium a plurality of zones and be divided into subregion such as a plurality of when inflator 5 is loose from being provided with in the zone that has diffusing gas slit S in the surface of air film 31; The port area of diffusing gas slit S when loosing gas, be arranged in downside etc. the subregion port area summation greater than be arranged in upside etc. the summation of port area of subregion.
The diffusing gas slit S of particularly, the arrangement of the vertical downside on the optional position of axis direction (for example 1 row) is slit width (diagram above-below direction width) is arranged the diffusing gas slit S of (for example 1 example) greater than its upside shape.That is, be this slit width and become big form gradually towards the part that becomes downside from the part that becomes the vertical upside of the inflator 5 that looses.
In the diffusing device of air 1 of said structure,, the air film 31 that looses is expanded and be spread in the processed water from the gas slit S that looses as micro bubble by the periphery of the air admission support tube of sending into from the air-supply of fan and through ventilating pit 3a 7 and the gap 35 of diffusing air film 31.Therefore, the micro bubble gas that on the long side direction of support tube 7, looses equably easily.

And, blistered air capacity (when setting the driven in rotation number of fan low) etc. more after a little while, had only from the air dispelling hole of the lower upside of hydraulic pressure and bubbled in the past; And the foaming that takes place from the air dispelling hole of the higher downside of hydraulic pressure is insufficient; Air dispelling hole at downside stops up easily, but according to this embodiment, even if wait in blistered air capacity more after a little while; Also can bubble equably, therefore be difficult for producing this problem at whole diffusing gas face.
In addition, for example when safeguard waiting air-supply that stops from fan, the air film 31 that looses adheres to support tube 7 with the gas slit S that looses because of the retractility (elasticity) of the air film 31 of loosing own and the pressure closing state of processed water.At this moment, the opening of the gas slit S that looses narrows down because of the retractility of the air film 31 that looses, the obstruction of diffusing gas slit S in the time of therefore can further preventing diffusing device of air 1 out of service.
As stated; The diffusing inflator 5 of this embodiment can bubble from the whole diffusing gas face of the inflator 5 that looses equably; And can prevent that air dispelling hole S from stopping up, thus can realize the reduction of the pressure-losses, therefore can the aerobic slot through the draining of aerobic microbially decontaminate be used preferred pin.
More than, preferred embodiment be illustrated of the present invention, but the present invention does not receive any qualification of above-mentioned embodiment.For example; Among Fig. 3; Summation about port area; The method of the summation of arranging greater than its upside as the summation that makes the arrangement that the vertical downside when loosing inflator is set shows the form of adjustment slit width, but also can utilize the diffusing gas slit of arrangement that the slit length (the left and right directions length of Fig. 3) that will constitute the hole is set as the vertical downside greater than the form of the diffusing gas slit of its upside arrangement.And, also can utilize the form that slit width and slit length both sides is set as the diffusing gas slit that the diffusing gas slit of the arrangement of vertical downside arranges greater than its upside.In addition, when air dispelling hole is not slit-shaped but shapes such as circle or pin hole, also can be set as the form that adds the wide aperture.In addition, above-mentioned slit width, slit length and aperture can be for becoming big form from the part that becomes the vertical upside towards the part that becomes downside gradually, also can be for become big form interimly.
And; The air dispelling hole of the arrangement of vertical downside can be made as the form of its quantity more than the air dispelling hole of its upside arrangement; At this moment, even if the shapes of air dispelling hole etc. are when the upside of the inflator that looses is identical with downside, also can be like a cork from the air dispelling hole foaming of the higher downside of hydraulic pressure.
In addition, if above-mentioned port area satisfy structure of the present invention just can appropriate change material or its rigidity etc. of diffusing inflator.For example, also the diffusing air film that replaces having retractility by the higher diffuser of the rigidity of moulding such as metal can be used, the air dispelling hole of the single tube diffuser of non-inside and outside dual pipe can also be applied in addition as the parts in full week of the periphery that covers support tube.
In addition, diffusing inflator of the present invention is not limited to carry out the purpose that the aerobic of processed water is handled, and can also use as the whipping appts of processed water.That is,, bubble, form convection current effectively, therefore the processed water in the steel basin effectively like the whole diffusing gas face of above-mentioned even air ground from the inflator that looses according to diffusing inflator of the present invention.
