Description
Technical field
The utility model belongs to sewage disposal device, and what relate to is the aerating apparatus for industrial sewage processing, and what be specifically related to is a kind of non-isometrical whirlwind-type aeration tube device for industrial sewage processing.
Background technology
In industrial sewage microbiological treatment process, in order to make microorganism in sewage keep long-term vital activity, need to ensure in sewage, to there is certain oxygen level.In order to ensure microorganism long term maintenance activity in industrial sewage pond, usually adopt aeration method, utilize aerator to constantly oxygen supply in sewage lagoon, according to aeration tube structure difference, existing aeration tube roughly can be divided into two kinds of boring aeration pipe and micropore aeration pipes.Boring aeration pipe is directly perforate on pipeline, and pressurized gas discharges and enters pond from tapping, and the method is easier to realize, and cost of manufacture is low, but dissolved oxygen efficiency is lower, can be because backing up of sewage causes pipeline scale to stop up during simultaneously due to intermittent oxygen supply; Micropore aeration pipe has higher dissolved oxygen effect relatively, but its complex structure, complex production process, production cost is higher, and complex structure installation and maintenance inconvenience, simultaneously because micropore aeration pipe hole is too small, and be directly exposed in sewage, therefore in operational process, easily result in blockage, need to frequently clear up, reduce equipment service efficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of non-isometrical whirlwind-type aeration tube device for industrial sewage processing, be used for improving effectively aeration area and dissolved oxygen efficiency of sewage treatment process, solve simultaneously and in servicely cause sewage to recharge causing the problem of line clogging because of liquid return.
The utility model is achieved by the following scheme: a kind of aeration branch pipe that comprises gas transmission main pipe, is connected to the gas transmission arm of gas transmission main pipe both sides, is connected with gas transmission arm for the non-isometrical whirlwind-type aeration tube device of industrial sewage processing, and gas transmission main pipe and gas transmission arm are tapered tube; Gas transmission arm is arranged at the both sides of the gas transmission main pipe longitudinal non-equidistance of lateral symmetry; Aeration branch pipe is arc, and the pipe end of aeration branch pipe is provided with screen cloth air outlet, and reverse checkvalve is equipped with on top.
Adopt the positively effect of technique scheme: the utility model all adopts tapered tube and gas transmission arm to arrange at the both sides of the gas transmission main pipe longitudinal non-equidistance of lateral symmetry gas transmission main pipe and gas transmission arm, make the aeration pipeline section gaseous tension in gas explosion operation more approaching, ensure that the bubble rate of dispersion that different positions place produces is uniformly dispersed with always mass transfer amount is basic identical; Arc aeration branch pipe, can make gas explosion air-flow rise in the shape of a spiral, after gas ejection, forms annular eddy flow, effectively improves aeration area, increases bubble pathway length, extends the duration of contact of bubble and water, improves dissolved oxygen effect; At the pipe end of aeration branch pipe, reverse checkvalve is installed, can be effectively solved and in servicely cause sewage to recharge causing the problem of line clogging because of liquid return.

Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further, but should not be construed as restriction of the present utility model:
Fig. 1 is the utility model aeration tube device one-piece construction schematic diagram, as shown in the figure, and the aeration branch pipe 3 that the utility model comprises gas transmission main pipe 1, is connected to the gas transmission arm 2 of gas transmission main pipe 1 both sides, is connected with gas transmission arm 2.
Gas transmission main pipe 1 is horizontally disposed, and gas transmission arm 2 is arranged in the both sides of gas transmission main pipe 1, and aeration branch pipe 3 is arranged in the both sides of gas transmission arm 2.Gas transmission main pipe 1, gas transmission arm 2 are non-isometrical pyramidal structure, and pipeline cone angle is 4 °.Gas transmission arm 2 is arranged at the both sides of the gas transmission main pipe 1 longitudinal non-equidistance of lateral symmetry, and concrete arrangement pitches is ascending successively according to 1.0:1.2:1.4:1.6:1.8:2.0: ...: N arranges, and wherein N is the arm ordinal number that spacing is arranged.
Fig. 2 is the plan structure schematic diagram of gas transmission arm and aeration branch pipe, structural representation after gas transmission arm is connected with aeration branch pipe is mainly provided in figure, Fig. 3 is that the axial-rotation 90 of Fig. 2 is spent elevational view, Fig. 4 is the left side view of Fig. 2, shown in Fig. 2, Fig. 3, Fig. 4, the longitudinal non-equidistance of gas transmission arm 2 lateral symmetry is arranged and connects gas transmission main pipe 1.In the present embodiment, gas transmission main pipe 1 one end diameter is 150mm, and the other end diameter is 50mm.Gas transmission arm 2 is four groups, and gas transmission arm 2 one end calibers are that 40mm, the other end caliber are 20mm, and annular radius is 300mm.The ascending 1.0:1.2:1.4 of being followed successively by of gap ratio between four groups of gas transmission arms 2 arranges, and symmetry is connected to the both sides of gas transmission main pipe 1.Gas transmission arm 2 is equidistantly arranged the both sides at gas transmission main pipe 1 are non-, make aeration pipeline section gaseous tension more approaching, ensure that bubble rate of dispersion that different positions place produces and total mass transfer amount are basic identical and be uniformly dispersed.Aeration branch pipe 3 is arc, and exit diameter is 15mm.Aeration branch pipe 3 is designed to arc, air draught can make aeration operation time after pressurization rises in the shape of a spiral, see Fig. 2 Middle Ring Line arrow mark, be used for improving effective aeration area, increase bubble pathway length, extend the duration of contact of bubble and water, improve dissolved oxygen effect, tangential direction design in air outlet is avoided causing line clogging because generation liquid return causes sewage to recharge.For ensureing to form annular eddy flow after gas ejection, extend the curved oblique top of aeration branch pipe 3, is designed with the angle of 8 ° with gas transmission arm 2 horizontal directions, sees arrow mark in Fig. 3.
