Description

Diffuser {Air supply device}

The present invention relates to an acid engine that removes pollutants by activating microorganisms by increasing dissolved oxygen in sewage and wastewater. More specifically, the amount of dissolved oxygen can be increased by miniaturizing air bubbles, and the backwater of sewage and wastewater is also reversed. To a diffuser with enhanced airtight protection against

Oxygen supply device is essential for wastewater treatment facility using microorganism. In particular, the aeration type aeration device, which is a kind of oxygen supply device, is composed of an aeration device, a header pipe, a blower pipe, a blower, and other accessories, and the air supplied by the blower is formed into fine bubbles through the air blower device and is ejected from the aeration tank. Water and air are agitated and mixed by the upstream formed thereby, so that the microorganisms need the air.

These air diffusers (hereinafter referred to as "acid engines") are classified into various types. Non-porous acid pipes have a large orifice, which generally have a large bubble and low aeration efficiency. Although mass production is possible, each has the disadvantage that the porous part is easily blocked by suspended matter and sewage.

Accordingly, an object of the present invention is to provide an acid pipe for wastewater treatment that is capable of mass production of microbubbles while being a non-porous acid pipe.

Another object of the present invention is to provide an acid pipe for treating wastewater with airtightness to prevent backflow of wastewater.

The main feature of the present invention for realizing the purpose of the present invention is that the lower part is screwed on the air supply pipe, has a conical shape that extends toward the top from the combined portion, the central portion is formed with a supply flow path communicating with the air supply pipe The supply passage has a immersion screw constrained toward the upper body; An internal diaphragm seated through the immersion screw in the body; An outer diaphragm seated to be penetrated by an immersion screw in an upper end portion of the body; And nuts and washers fastened to the immersion screw exposed to the outside of the external diaphragm to fix the internal and external diaphragms.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, the diffuser 10 is arranged inline with the bottom pipe portion of the air supply pipe 3 that is piped from the top of the waste water reservoir 1 to the bottom as shown in FIG. Therefore, the air compressed by the driving of the blower 5 located on the upper side of the air supply pipe 3 is supplied to each diffuser 10 through the air supply pipe 3, and in each diffuser, the air is supplied to the fine air. When saturated, bubbles are discharged into the waste water reservoir 1.

The diffuser 10 of the present invention having such a function has a body 20 screwed onto the air supply pipe 3, an internal diaphragm 30 seated in the inner space of the body 20, and the body External diaphragm 40 seated on the upper end of the 20, and coupling means for coupling the body 20 and each diaphragm.

The body 20 has a conical shape that extends from the bottom to the top coupled to the air supply pipe (3), the supply passage 22 in communication with the air supply pipe (3) is formed in the center, the supply flow path In the inside of the 22, the immersion screw 24 is provided to the upper portion is restrained to be installed so as not to be separated from the supply passage (22). In addition, an uneven portion 26 is formed at an upper end of the body 20 to serve to finally refine the primary and secondary micronized bubbles by the inner and outer diaphragms 30 and 40 to be described later. Since the uneven portion 26 has a sharp shape at each corner, the uneven portion 26 becomes a condition that can subdivide the bubbles as compared to the curved edges when the bubbles are discharged.

The inner diaphragm 30 is a disk-shaped rubber which is seated inside the body 20 with a central portion penetrating through the immersion screw 24 to primarily micro-bubble the air discharged through the supply passage 22. Play a role. In particular, the inner diaphragm 30 has an edge portion in contact with the inner wall surface of the body 20 is thinner than the center portion to allow air to be discharged between the edge of the inner diaphragm 30 and the inner wall surface of the body 20. At the time, the air is made fine by vibration of the edge part.

The outer diaphragm 40 is also a disk-shaped rubber seated on the upper end of the body 20 while the center portion is penetrated by the immersion screw 24 serves to further refine the air bubbles passing through the inner diaphragm 30 again. do. The outer diaphragm 40 is formed to have a uniform thickness as a whole, but is formed thicker than the inner diaphragm 30. The reason is because the external diaphragm 40 is directly affected by the hydraulic pressure, it should have a strength that can withstand the hydraulic pressure. When the thickness of the external diaphragm 40 is designed to be thinner than the hydraulic pressure, foreign matter or waste water may be introduced into the interior. On the contrary, when the thickness of the external diaphragm is thick, the vibration phenomenon (vibration phenomenon) for miniaturizing the bubbles is reduced. Therefore, the thickness of the external diaphragm 40 should be designed in consideration of the relationship between the water pressure in the waste water reservoir 1 and the air discharge pressure.

Coupling means for coupling the body 20 and the central portion of each diaphragm includes an immersion screw 24, the washer 51 and the nut is fastened to the immersion screw 24 on the outside of the outer diaphragm 40 (53) is further included.

As described above, the present invention can increase the amount of dissolved oxygen in the waste water reservoir by microbubbling the air to be supplied in multiple stages (three stages). Therefore, by activating the microorganisms there is an advantage that can increase the efficiency of removing contaminants.

In addition, the application of the double diaphragm strengthens the airtight force to completely block backflow of waste water.
