Abstract

An aerator has one, or two, or four, or multiple aerating pipes which is a millipore tube made of polyethene or poly-propene and has skeleton or not. For the single-tube aerator, the aerating tube is connected with air feeding tube via two short jointers and an elbow. Its advantages are sufficient contact with water and high utilization rate of oxygen.

Description

Aerating apparatus

Technical field

Aerating apparatus of the present invention is the biological treating equipment that is used for tap water and sewage disposal, in particular for the aerating apparatus of water body oxygenation, belong to the environmental protection equipment field.

Background technology

For the water body oxygenation is a gordian technique in the black water aerobe chemical treatment technology.In the biochemical method of water treatment, one of applied major equipment of aerobic activated sludge process is an aerating apparatus.In the prior art, aerating apparatus adopts fixed mounting means more, and promptly aerator installs and fixes under water the air line.Because the underwater position of aerator is a limitation changeless, that add plate-type aerator configuration itself, above-mentioned aerating apparatus causes oxygenation inhomogeneous unavoidably, too high and can produce eddy flow and make gas residence time of ducking in drink too short near the oxygenation of aerator part, so oxygen-transfer efficiency is lower.Through picking up rope: 98204611.1 " a kind of floated microporous aeration devices ", be characterized in that described micro-hole aerator is the film tube type aerator of oval column type, its internal layer for be communicated with ventpipe and tube wall on the stereoplasm tube of several open-works is arranged, this stereoplasm tube outer tightly around be wrapped in one deck soft, resilient plastics or gum sleeve, be evenly distributed with several are closure state under non-ventilation situation micropore on the described sleeve pipe; Micropore on the aerator sleeve pipe is the micropore of cruciform otch; " 03209634.8 a kind of suspension chain type aerating apparatus ", this film tube type aerator, its internal layer for be communicated with ventpipe and tube wall on the stereoplasm tube of several open-works is arranged, this stereoplasm tube outer tightly around be wrapped in one deck soft, resilient plastics or gum sleeve, be evenly distributed with several are closure state under non-ventilation situation micropore on this sleeve pipe; It is that gas is pressed into " stereoplasm tube is outward tightly around being wrapped in the soft film of one deck " realization aeration performance that each environmental protection unit's great majority is used film tube type aerator, fatal shortcoming, the pressure inequality, and mantle easily drum is broken.

Summary of the invention

The purpose of this invention is to provide a kind of material and replace soft film, aerating apparatus simple in structure, that the life-span is long, coefficient of oxygen utilization is high.

The objective of the invention is to realize by following scheme.

Aerating apparatus is made up of aeration tube, counterweight, elbow, and aeration tube is made up of skeleton, microporous pipe, and skeleton outer end and microporous pipe inwall are fitted; Aeration tube is exactly a microporous pipe; The microporous pipe material is high-molecular polythene, polypropylene tube; High-molecular polythene, polypropylene tube are for sintered pipes or melt and spray pipe; Single tube aerating apparatus two-end structure symmetry; The one end structure is: screw thread is fixedlyed connected between aeration pipe end and the counterweight; The aeration tube termination is communicated with short circuit by nut and seal washer, between bonding; Be communicated with between the short circuit the other end and the elbow, elbow is communicated with by short circuit, short circuit the other end gas-filled valve to be connect.

Effect of the present invention is very outstanding: enter air in the water by micropore aeration pipe, can fully contact with water, the coefficient of oxygen utilization height can reach more than 25%, compares with traditional aerator of use and economizes on electricity more than 30%, and the polyethylene sintered pipes can carry out back flushing, long service life.

Embodiment

Fig. 1 is the two-tube aerating apparatus structural representation that 2 aeration tubes compose in series, and aerating apparatus is by aeration tube 1, counterweight 2, nut 3, short circuit 4, elbow 5, short circuit 6, seal washer 7, suspension ring 8, support 9, union lever 10, threeway 11, microporous pipe 1-1, skeleton 1-2.

Each element brief introduction among the figure:

Aeration tube 1: material is by the waterproof anticorrosive material; Counterweight 2: material is cast iron, carbon steel or stainless steel, cast member or workpiece; Fitting nut 3: material is an ABS plastic, moulding; Short circuit 4: material is an ABS plastic, standard tubing short circuit; Elbow 5: material is an ABS plastic, moulding; Short circuit 6: carbon steel or stainless steel pipe, mechanical workout; Seal washer 7: RUBBER O RunddichtringO; Suspension ring 8: carbon steel or stainless steel standard part; Support 9: carbon steel or stainless steel, weldment; Union lever 10: carbon steel or stainless steel, machined piece; Threeway 11: material is carbon steel or stainless steel, standardized component; Short circuit 12: material is an ABS plastic, standard tubing.

According to sewage disposal Aerobic Pond size, structure and sewage different in kind, aeration tube assembling divides patterns such as a single tube, two-tube and multitube, and structure is seen accompanying drawing.

At first, well imagine single tube aerating apparatus two-end structure symmetry by Fig. 1; The one end structure is: screw thread is fixedlyed connected between aeration tube 1 end and the counterweight 2; Aeration tube 1 termination is communicated with short circuit 4 by nut 3 and seal washer 7, between bonding; Be communicated with between short circuit 4 the other ends and the elbow 5, elbow 5 is communicated with short circuit 6 the other ends gas-filled valve to be connect by short circuit 6.

Fig. 1 is two-tube aerating apparatus, is to be connected in series by two aeration tubes on single tube aerating apparatus basis; The butt joint of two aeration tube adjacent both ends is supported by support 9; Two aeration tubes, 1 outer end is fixing by two counterweights 2 respectively, and is fixedly connected by union lever 10 between two counterweights 2; Two aeration tube outer ends are connected in series elbow 5 and the 6 fixing connections of outer short circuit, the outer short circuit 6 at two ends, left and right sides gas-filled valve to be connect respectively more respectively by the nut 3 and interior short circuit 4 of two band seal washers 7.
