Introduction
1, the decline of diaphragm hole of gas diffusion aerator rubber sheet is made of high quality synthetic rubber, rubber diaphragm diffusion of small air bubble diameter, gas-liquid boundary area is large, therefore, has high mass transfer rate, high oxygen transfer efficiency, thus, compared with other current aeration device, can greatly reduce power consumption, the operation of the sewage treatment cost reduction.
2, rubber diaphragm on a large number of autistic perforation, as oxygen filling and stop running, the hole can be automatically opened and closed, therefore, do not produce pore jams, contamination and other ills, at the same time, the air into the aerator does not need to remove dust purification, stop running when the aeration tank, sewage, the mixture will not difficult, can reduce a large number of operating cost and maintenance workload.
3. Because the diaphragm type microporous aerator can be fully distributed at the bottom of the aeration tank and uniformly dissolved oxygen in the tank, it can be applied to all kinds of pool types and depths, and can also transform the original aeration tank to improve its effect.
4, because the diaphragm type microporous aerator gas diffusion plate is made of high quality rubber, it has good physical and mechanical properties, trays, accessories and air pipes are made of engineering plastics, polypropylene material, so it is not afraid of corrosion, to a large extent to reduce the workload of operation and maintenance.
The basic structure
Diaphragm decay aerator system is mainly composed of aeration hole bottom, the spiral gland, air flow sheet, synthetic rubber diaphragm and other parts, its component material adopts engineering plastics, assembly, as long as microcellular rubber diaphragm on the air flow board, and in line with seal aeration inside the bottom seat, then use screw to tighten gland.
The air pipe adopts polypropylene or ABS engineering plastic pipe (according to the user needs to choose), welded on the top of the 3/4 internal thread joint, the micro-hole aeration head is directly screwed on the cloth pipe, easy to install and use, is conducive to maintenance and repair.
Ymb-type microporous aerator diameter is D=260mm(or 250) : Type ⅱ D=215mm(or 189) on the synthetic rubber diaphragm has 2100 to 2500 open and closed holes arranged according to certain rules. When inflating, the air enters evenly between the rubber diaphragm through the air distribution pipe and the air flow plate. Under the action of air pressure, the diaphragm is slightly inflated and the holes are opened to achieve the purpose of air distribution diffusion. As the pressure between the diaphragm and the air equalizing plate drops gradually, the hole is gradually closed. When the pressure disappears, the diaphragm is compacted on the air equalizing plate due to the action of water pressure and the resilience of the diaphragm itself.
Due to the above configuration and the good properties of the diaphragm itself, it is impossible for the mixture in the aeration tank to backflow and therefore not to contaminate the holes. On the other hand, when the holes are open, the small amount of dust in the air due to the elastic action of the rubber does not cause the gap of the aerator to be blocked.
