Embodiment Construction

[0013] The titanium microporous aeration disc of the present invention will be further described below through specific implementation methods.

[0014] The chassis (9) of the titanium microporous aeration pan is circular, and is divided into an upper pan cover (6) and a lower pan cover (1). There are fixing holes (2) around the chassis (9), and through the fixing holes (2) Fixed with titanium perforated panel (7). The sealing strip (3) on the titanium metal porous panel (7) cooperates with the chassis (9) upper plate cover (6) and lower plate cover (1) to seal. A hemispherical cavity (8) is formed between the titanium metal porous panel (7) and the lower plate cover (1). There are many tiny pores on the titanium metal porous panel (7), and the equivalent diameter of the pores is 15-25 μm. 2 There are 5000-8000 micropores on the area. In order to connect the trachea, there is a ventilation hole (5) in the center of the lower plate cover (1). The chassis (9) and the air duc...

Abstract

The invention provides a titanium micro-pore aeration disc, belonging to a waste water treatment technology. The titanium micro-pore aeration disc consists of a bottom plate, titanium alloy porous panels, and an air guide tube; the bottom plate is round; fixing holes are arranged around the bottom plate; the bottom plate is divided into an upper plate cover and a lower plate cover; the titanium alloy porous panels are mounted between the two plate covers; a plurality of air vents are arranged on the titanium alloy porous panels; the air vents are 15-25 microns in diameter; and 5000-8000 micro-pores are arranged on the titanium micro-pore aeration disc in an area of 1 square meter. Sealing strips on the titanium alloy porous panels are sealed with the upper plate cover and the lower plate cover of the bottom plate. A semispherical cavity is formed between the titanium alloy porous panels and the lower plate cover. The bottom plate and the air guide tube are manufactured by machining a stainless steel material; and the titanium alloy porous panels are formed by machining titanium alloy powder. The titanium micro-pore aeration disc has the advantages of small aperture, large injection pressure, and simple structure, and the vents are not easy to be blocked. Furthermore, the titanium micro-pore aeration disc has the most outstanding advantages of high resistance of corrosion caused by ozone oxidation and organic chemical waste water, particularly aniline-contained waste water, and long service life.

Description

technical field [0001] The invention relates to a waste water treatment technology, in particular to a titanium microporous aeration disc for diffusing gas into water. Background technique [0002] In the biochemical treatment process of wastewater and sewage, the aeration device is mainly used to oxygenate the water body. Under the same conditions, the microporous aeration device has better oxygenation performance and high efficiency than the large and medium bubble aerators, but its pores are easy to block. In order to solve this problem, some aeration devices are equipped with a rubber diaphragm outside the microporous shell, such as the aeration device of the utility model patent of CN2339571Y, which is to tightly wrap a layer of rubber sleeve outside the microporous hard tube, so A plurality of micropores that are closed under non-ventilated conditions are evenly distributed on the casing, and the micropores are opened by the pressure of the air in the hard tube under ...
