Description

Nano Aeration Tube

technical field

The utility model relates to water treatment equipment, in particular to a device for treating industrial sewage by adopting membrane biological reaction technology.

Background technique

The microporous aeration tube is a device that sends air to water in sewage treatment. Known various microporous aerators, the upper end of the air intake channel directly passes through the support plate, communicates with the inside of the rubber diaphragm, ventilates through the middle hole, and then distributes to the holes of the rubber diaphragm. A kind of " microporous aerator " (ZL022376003) disclosed as Chinese patent document, it still adopts the rubber diaphragm all over perforation, only there is the difference of air inlet channel, and the pore specific surface area of its same existence aeration hole is little, further The problem of large air resistance and large pressure loss.

Utility model content

The purpose of the utility model is to provide a nanometer aeration tube with large pore specific surface area and small pressure loss aiming at the problems and deficiencies of the prior art.

The purpose of this new model is achieved through the following technical proposals: a nanometer aeration tube, including the main pipe of the aeration pipeline, the main pipe of the aeration pipeline is provided with air holes, and a tubular nut is respectively screwed on the two ends of the main pipe The front ends of the two nuts are movably set on the main pipe, and an O-ring is arranged between the two, and the fiber aeration pipe is set on the front ends of the two tubular nuts, and is crimped between the two shoulders of the two nuts.

The surface of the fiber aeration pipe is coated with a layer of nano film.

The key to the above technical solution is that the fiber aeration tube is made of composite modified fiber material, and the diameter of the modified fiber determines the porosity and pore size of the aeration tube. In this way, compared with mechanical drilling products, the new model can ensure Higher porosity and uniform pore size, for example, the pore size is 60 microns. Therefore, the shortcomings of uneven pore distribution, small pore specific surface area (referring to the ratio of pore area to surface area), and large pressure loss are fundamentally solved (for example, if holes are opened on the rubber diaphragm of the current microporous aerator Too much and too dense will inevitably affect the mechanical strength of the diaphragm).

Compared with the prior art, the new model has the following characteristics and advantages:

1. Anti-acid and alkali oil phenol, high temperature resistance, no hardening, no embrittlement, no crusting, suitable for aeration of chemical liquids.

2. Long service life, up to 20 years.

3. The pressure loss is small, compared with traditional aeration products, it can save energy by 15%-20%. Aeration Fiber Tube The tubular air distribution layer allows air to diffuse around its circular cross-section. At the beginning of aeration, due to the existence of the water level difference, the air is only aerated through the diffusion layer at the α angle (Figure 2), that is, only a part of the air distribution layer participates in aeration, and the air distribution layer is rich, which is precisely the nano A very important advantage of aeration tubes. Because the fiber aeration tube with a unique structure is a self-regulating system, as the running time increases, the resistance loss of the air distribution layer increases, and it can rely on the change in the width of the aeration belt (that is, the α angle becomes larger) Air, so as to ensure the stability of the air resistance loss of the aerator and minimize the energy consumption of the fan. At the same time, when the fan stops and restarts, the accumulated water inside the aeration pipe can be squeezed out by the air through the air distribution layer in the lower part. Therefore, the aeration system using the tubular aeration tube does not need to set a special drain pipe and drain valve.

4. Prevent sewage from flowing backward.

5. It is easy to install and disassemble, easy to maintain, and easy to clean and regenerate the fiber aeration pipe.

6. The surface of the aeration fiber tube is coated with a special nano-film, so the surface of the tube body is smooth, and it is not easy to fix the biofilm, so as to keep the airway unobstructed, improve the anti-pollution performance of the aeration tube, and have the ability to resist acid and alkali , especially for industrial wastewater with high acidity and alkalinity.

Detailed ways

Figure 1 shows that the nano aeration tube is mainly composed of an aeration pipeline main pipe 6, two tubular nuts 1, 7, a fiber aeration tube 4, a sealing ring, a gasket and the like. There is a ventilation hole 5 on the main pipe 6 of the aeration pipeline. The two ends of the main pipe are respectively screwed with tubular nuts 1 and 7. The front ends of the two nuts are movably sleeved on the main pipe, and an O-shaped The sealing rings 3, 8 and the fiber aeration tube 4 are set on the front ends of the two tubular nuts and crimped between the two shoulders 1a, 7a of the two nuts. The surface of the fiber aeration pipe 4 is coated with a nano film. The fiber aeration pipe 4 is provided with ventilation holes all over, and the aperture of the ventilation holes is 60 microns. Referring to Fig. 2, there are 4 ventilation holes evenly distributed in the middle of the main pipe 6 of the aeration pipeline. Gaskets 2 and 9 are arranged between the fiber aeration pipe 4 and the shoulders of the two nuts. In Fig. 1, the two tubular nuts 1 and 7 have the same structure, and the direction in which the nuts screw in along the mother pipe is defined as the front end of the nut. The tubular nut can be divided into a front end with a larger diameter and a rear end with a smaller diameter. The inner wire on the rear end of the nut is spirally connected with the outer wire on the outer wall of the mother pipe, and the front end of the nut is slidingly fitted with the mother pipe with a certain gap. An O-ring seal is set on the joint surface between the two to play a sealing role.
