Overview

200 type brown corundum aeration head: disc or hemispherical, made of brown corundum material. The finished brown corundum aeration disc should be made of high-quality natural raw material sand (30 mesh~80 mesh irregular cylindrical particles mainly made of high alumina bauxite, processed by high-temperature smelting and ball milling, with Al2O3 content of ≥ 95%) and high-temperature clay (commonly known as kaolin) added with pore forming materials and mixed evenly, then mechanically extruded or pressed into shape, and then sintered at 1300 degrees Celsius. The use of recycled sand is strictly prohibited. The Al2O3 content obtained by sintering is ≥ 85% (referring to the finished alumina aeration disc Al2O3 after sintering)

Product Details

200 type brown corundum aeration head

The brown corundum aerator is suitable for working under the given urban sewage quality conditions.

200Brown corundum aeration headUse corundum sand with high hardness, stable chemical properties, and strong corrosion resistance(Al2O3)Ceramic adhesive is sintered at high temperature, with high comprehensive mechanical strength and porosity greater than45%The pore distribution is uniform, with an average pore size150~180MmLow ventilation resistance. Compressive strength greater than or equal to40MPaThe bending strength is greater than or equal to20MPaThe weight loss rate due to acid corrosion is1%~2%The weight loss rate due to alkali corrosion is3%~5%The material of the aeration disc is resistant to urban sewage corrosion, not easy to grow microbial films, and not easy to adhere to other pollutants such as oil stains.

bottom of the poolUPVCThe performance of air pipelines and fittings meets national requirements, and the pipeline system should meet the system pressure test standards; The adjustable height range of the level adjuster is not less than30mmThe specifications of the expansion bolts used in the system should meet the requirements for support and anchoring. At the midpoint of each distribution pipe, supports should be installed at tees and corners, and the support system should provide sufficient capacity to withstand the impact of water hammer at the end of each distribution pipe. The maximum support spacing should not exceed2mTo ensure system security and secure fixation. Each support consists of three parts: a foundation, an adjustable support, a pipe clamp, and anchor bolts.

The 200 brown steel jade aeration head should not allow sewage to infiltrate the aeration system under any circumstances when the aeration is stopped. It should be able to aerate normally even after a long period of gas stoppage, and have anti clogging, anti backflow, and anti tearing properties.

The aerator should be easy to replace, with limited displacement, and the pipe frame can be vertically adjusted50mm.

The arrangement of the aeration system should ensure effective mixing anywhere in the tank without the need for a mixer.

The aerator should meet the following characteristics:

1）Diameter of aeration discF200mm；

2）Effective air flow rate:≥2m³/h·only(+20℃，101.3KPa)；

3）In terms of service area0.5m²/a(水深6mClear water)Under certain circumstances, oxygenation capacity≥0.28kgO₂/ h(Ф260mmVentilation rate2.0m³/h·only)；

4）In terms of service area0.5m²/a(水深6mClear water)Under certain circumstances, the standard aeration efficiency≥8.7kgO₂/kWh(Ф200mmVentilation rate2.0m³/h·only)；

5）Oxygen utilization rate(水深6mClear water)≥34%clear waterF200mmVentilation rate2.0m³/h·only)；

6）Resistance loss:≤3500pa.
