Abstract
The utility model discloses an aerator for making oxygen effectively dissolved in water in biochemical sewage treatment, particularly an aerator utilizing micropores for air guide. The utility model is composed of an air inlet pipe, a supporting pipe and a thin film, wherein, an air distributing channel and a water filling chamber are arranged on the supporting pipe, the air inlet pipe is fixed on the supporting pipe and is communicated with the air distributing channel, and the thin film provided with micropores coats the supporting pipe. During the aeration, air passes through the air inlet pipe and the air distributing channel and then is sent out from the micropores of the thin film. The utility model has the advantages of high oxygenizing efficiency, corrosion resistance, simple structure, and convenient installation and maintenance, and blockage and dirt sedimentation are not easy to occur.
Description
The utility model relates to makes oxygen effectively dissolve in aerating apparatus in the water in a kind of sewage biochemical treatment, especially the aerating apparatus by the micropore air guide.
In the sewage biochemical treatment, particularly big-and-middle-sized sewage work, the power consumption of aerating apparatus accounts for the 60-70% of entire sewage factory current consumption, and the efficient of aerating apparatus directly influences effect, construction investment and the working cost of sewage disposal.Existing aerating apparatus is generally formed by inlet pipe and conductive gas, and conductive gas adopts titanium, pottery, silica, diamond spar material to make the conductive gas that has many micropores mostly, and gas enters in the conductive gas again and sends in the water through its micropore through being pumped into inlet pipe.The deficiency of this class aerating apparatus is: micropore easily stops up, and then causes maintenance workload bigger; In addition,, then need the gas of input is carried out special dedusting, oil removing and processing of rust removing, operation and maintenance cost are improved for preventing the obstruction of micropore.
The purpose of this utility model provides a kind of aerating apparatus, and it has the oxygen-transfer efficiency height, is difficult for obstruction, corrosion-resistant and easy for installation and simple in structure.
For achieving the above object, the utility model comprises inlet pipe, also comprise supporting tube and film, have gas distribution groove and water filling cavity on the supporting tube, inlet pipe is fixed on the supporting tube by bolt and sealing-ring, inlet pipe communicates with the gas distribution groove of supporting tube, has micropore on the film, and passes through the circumferential band envelope outside supporting tube.During aeration, gas is sent in the water through the gas distribution groove of supporting tube, the micropore on the film through being pumped into inlet pipe again.
For guaranteeing that film can heave when the aeration slightly, each micropore all can be supplied gas, the gas distribution groove place that is positioned at supporting tube at film does not offer micropore, all offers micropore equably at other position, is provided with tongue at the relative position place of the gas distribution groove of supporting tube.
Above-mentioned supporting tube and film are made by polypropylene.
The utility model is owing to adopt the film that has micropore to make conductive gas, film shakes slightly and heaves in aeration, its micropore opens slightly, gas is diffused in the water through micropore, form many micro-bubbles, both added the contact area of atmospheric and water, improved oxygen-transfer efficiency, and made biofouling be difficult for being deposited on the film again; When stopping air feed, film is close on the supporting tube under the elastic force and the effect of hydraulic pressure of self, its micropore closure, and water can not enter in the inlet pipe; Because film is thinner, and the passage of micropore is shorter, a small amount of dust also can pass through in the gas, is difficult for resulting in blockage again.In addition, that the utility model also has is corrosion-resistant, installation, advantage easy to maintenance and simple in structure, can be widely used in sewage biochemical treatment and the culture fishery.
Provide embodiment of the present utility model and accompanying drawing below, and be described further in conjunction with the accompanying drawings:
Fig. 1 is a cut-away view of the present utility model.
By shown in Figure 1, inlet pipe 1 is fixed on the supporting tube 10 by bolt 2, nut 3, packing ring 12 and sealing-ring 4,5,6.Have gas distribution groove 7, tongue 14 and water filling cavity 8 on supporting tube 10, inlet pipe 1 communicates with gas distribution groove 7 on the supporting tube 10.Film 9 passes through circumferential band 11 envelopes on supporting tube 10.For making film 9 each micropore when aeration bubble that can both spue, gas distribution groove 7 places that are positioned at supporting tube 10 at film 9 do not offer micropore, all have micropore 13 at other position, are provided with tongue 14 at the opposite location place of the gas distribution groove 7 of supporting tube 10.During use, aerating apparatus is installed in the sewage disposal trench bottom, can be full of water in the water filling cavity 8, to eliminate the influence of buoyancy to aerating apparatus.Gas enters between the gas distribution groove 7 and film 9 of supporting tube 10 through being pumped into inlet pipe 1 again, under the elastic effect of air pressure and film 9 self, film 9 is heaved slightly, its micropore 13 also opens slightly, and gas spreads out from micropore 13, forms a large amount of micro-bubbles; Because the air pressure that pumps into is subjected to the influence of various factors, always slightly fluctuation then makes film 9 also produce small vibrations when aeration, and this vibrations have brought great benefit to the deposition that prevents biofouling.When stopping air feed, film 9 is close on the supporting tube 10 its micropore 13 closures under the effect of self elasticity and hydraulic pressure.
