Abstract

The utility model relates to an oxygenation diffusion device for an oxygen supply system in the water. A circular or rectangle gas distributing board with micropores are tightly ferruled on a skeleton through a ferrule to form a gas distributing chamber, the oxygen enters the gas distributing chamber through a gas inlet pipe to travel through micropores on the gas distributing board, and a large number of air bubbles are formed in the water, so the oxygenation diffusion device can enlarge the gas-liquid contacting area. The oxygenation diffusion device has the advantages of simple structure, corrosion resistance, convenient operation, low cost and good performance, and the oxygenation diffusion device is easy to be blocked.

Description

Plate type medium microporosity aerator

The utility model relates to a kind of oxygenation dispersion device that is applied to oxygen system in the water.

The aerobe method of chemical treatment of sewage be unable to do without oxygen, and is required when the decomposing organic matter for microorganism for guaranteeing to have in the water enough dissolved oxygens, must charge into oxygen by artificial Xiang Shuizhong.The aerator kind of using both at home and abroad is more at present, air pocket and middle microbubble two big classes during only blast aeration equipment just can be divided into.Advantages such as though there is not obstruction in middle air pocket class aerator, airing system is simple, and the operation operational management is convenient, but coefficient of oxygen utilization and dynamic efficiency are lower, the energy consumption height, not too suitable for large-scale wastewater treatment plant.The mid-80 China has introduced the pottery of the circular and rectangular plate type of bell-jar, micro-hole aerator in the titanium plate from Britain.Introduced micro-hole aerator the hard circular pipe type from the U.S., Japan.Though these aerators have coefficient of oxygen utilization and dynamic efficiency height, save the advantage of energy consumption, but exist easily and stop up, air will purify, blower fan can not leakage of oil etc. requirement, operate the operational management complexity.

The purpose of this utility model is that a kind of both can to have satisfied large-scale wastewater treatment plant biochemical treatment aeration aerating required in design, also can be applicable to the difficult obstruction in the middle or small sewage treatment, corrosion-resistant, convenient operation and management, cheap, can improve the aerator of coefficient of oxygen utilization and dynamic efficiency.

Board-like middle micro-hole aerator described in the utility model divides rectangular flat formula and circular flat two series, and it is made up of air distribution plate, hoop, plenum chamber, inlet pipe four parts.Air distribution plate is a plastic cement material, on have a large amount of eyelets.Plenum chamber is made of the round or square type concave surface skeleton of air inlet port the air distribution plate lock ring with being in the middle of the plastic injection-moulded one-tenth on skeleton hoop.Air enters plenum chamber from inlet pipe, enters in the sewage by the micropore on the air distribution plate then, produces a large amount of micro-bubbles, finishes efficient oxygenation thereby strengthen the gas-to-liquid contact area.

Board-like middle micro-hole aerator simple structure described in the utility model has and does not stop up, and corrosion-resistant, oxygenation capacity is good, convenient operation and management, the advantage that cost is low.

With reference to the accompanying drawings board-like middle micro-hole aerator structure described in the utility model is elaborated below.

Embodiment 1:

With injection molding is a circular concave surface skeleton 4, middle perforate links to each other with inlet pipe 5, plastic cement is injection molded into circular air distribution plate 1, blade with 2mm, prick countless apertures in the above, then by steel wire hoop 3 lock rings on skeleton, make between skeleton concave surface and the air distribution plate to form a space as plenum chamber 2.

Embodiment 2:

With injection molding is a rectangle concave surface skeleton 4, middle perforate links to each other with inlet pipe 10, plastic cement is injection molded into rectangle air distribution plate 6, blade with 1mm is pricked countless apertures in the above, then by plastics hoop 8 lock rings on skeleton, make between skeleton concave surface and the air distribution plate to form a space as plenum chamber 7.

Claims

1, a kind of board-like middle micro-hole aerator is characterized in that it is the air distribution plate that has a large amount of micropores by top, by hoop air distribution plate is fixed on the plenum chamber that forms on the concave surface skeleton, and inlet pipe three parts constitute;

2, board-like middle micro-hole aerator according to claim 1 is characterized in that the air distribution plate material is a plastic cement.
