Background technology
At present in biological sewage treatment aerobic method technique and aquaculture, microorganism in water, animals and plants will consume the dissolved oxygen in water body, need to utilize aerating apparatus in water, to be filled with air to maintain the concentration of dissolved oxygen in water.Aeration mode common at present has blast aeration and mechanical aeration, aerating apparatus has the multiple patterns such as tubular type, disc type, table expose to the sun, but generally have that bubble is large, bubble distribution is uneven, solarization air cap easily blocks, drag losses is large, coefficient of oxygen utilization is low, energy consumption is large, water easily pours in down a chimney, easy aging, high cost shortcoming.
The micro-pore aeration flexible pipe that development in recent years is got up adopts the manufacture of polyurethane class high molecular material, is equipped with close battle array micropore (Figure 11) in ultra-thin hose surface, and produce micro-bubble, its every aeration performance index all improves.But the micropore on aeration flexible pipe is in the market single size vertical masonry joint hole (Figure 12, Figure 13), is uniformly distributed in hose surface.Flexible pipe adopts elastomeric polyurethane material, and during zero air flow, micropore can close voluntarily.This kind of aeration flexible pipe has following shortcoming:
Micropore adopts vertical masonry joint hole, during ventilation, vertical masonry joint hole is through-flow is formed by the inside and outside differential pressure effect hose surface tensile elasticity deformation of pipe, areal stretch elastic deformation stress is large, aeration resistance is lost large, areal stretch elastic deformation stress distribution is uneven, produces region of stress concentration at vertical masonry joint two ends, can fatigure failure be caused, shorten flexible pipe work-ing life.
Micropore adopts single size, and according to hydrodynamic characteristic, in water, the hydraulic pressure corresponding to micropore of different positions is all different, under certain venting pressure, greatly, bubble battle array skewness, number of bubbles reduces for the number of bubbles that on aeration flexible pipe, different water depth micropore produces and size difference.
Micropore is uniformly distributed in hose surface, and make a considerable amount of bubble interval near, micropore irrational distribution, has increased the weight of mutually dry between bubble scratching, and is degrading the dispersity (Figure 14, Figure 15) of bubble battle array.
These shortcomings above-mentioned cause that micro-pore aeration flexible pipe coefficient of oxygen utilization is in the market not high, energy consumption is high, oxygenation capacity is low.
