Abstract
A variable micro holes aeration soft pipe of the utility model comprises an improving PVC plastic soft pipe body of chemical fabric reinforcing of which pipe wall thickness is lesser than 2 millimeters and vertically equipped with at least two micro holes. The lengths of the micro holes are bigger than the widths and the micro holes are separately and evenly arranged. The out side of the pipe wall is covered with a silver type inorganic antibiotic coating layer of nano layer shape. The pipe body is soft structure and can inflate in aeration but be flattened without aeration by the function of hydrostatic pressure to be helpful for preventing sewage mud from entering the pipe body. The micro holes on the pipe periphery diameter surface can be in aeration and the diameters of the micro holes can be enlarged when the air pressure is increased. The utility model can respectively generate the micro diameter air bubbles of which diameters or air bubble diameters are smaller than 3 mm in water and the lifting speed of the air bubble is slow. The utility model has even air distribution, high oxygen utilizing rate, straight and short air flue, small atmospheric pressure loss and energy saving. The silver type inorganic antibiotic coating layer of nano layer shape on the surface of the pipe body can enable the surface of the pipe body be smooth without easy biological film fixing and keeps the air flue to be fluent.
Description
Technical field:
The utility model relates to water treatment device, relates in particular to sewage biochemical treatment engineering, particularly a kind of aerating apparatus, and concrete is a kind of variable micro-pore aeration flexible pipe.
Background technology:
In the prior art, become industrial sewage and city domestic sewage biochemical treatment engineerings such as the hole aeration flexible pipe is widely used in petrochemical industry, printing and dyeing, weaving, food, brewages, pharmacy, process hides, papermaking, when disposing of sewage, be arranged at intervals with micropore on the tube wall of change hole aeration flexible pipe, becoming the hole aeration flexible pipe is immersed in the water, when stationary state, micropore is closed state, after feeding high-pressure air in the aeration flexible pipe of change hole, micropore bulging and micropore spreading voluntarily under the effect of gas, gas passes through from micropore, and Xiang Shuizhong provides dissolved oxygen, to carry out biochemical treatment.Owing to usually contain microorganism in the sewage, microorganism forms microbial film, and microbial film anchors at the tube wall outside that becomes the hole aeration flexible pipe, can be blocking microporous, and stop gas from variable micropore, to pass through, thereby influence biochemical treatment efficient.
Summary of the invention:
Technical problem of the prior art to be solved in the utility model is: because in the prior art, become industrial sewage and city domestic sewage biochemical treatment engineerings such as the hole aeration flexible pipe is widely used in petrochemical industry, printing and dyeing, weaving, food, brewages, pharmacy, process hides, papermaking, and usually contain microorganism in the sewage, microorganism forms microbial film, microbial film anchors at the tube wall outside that becomes the hole aeration flexible pipe, can be blocking microporous, stop gas from micropore, to pass through, thereby influence biochemical treatment efficient.
The utility model is that the technical scheme that solution above-mentioned technical problem of the prior art is adopted provides a kind of variable micro-pore aeration flexible pipe, described this variable micro-pore aeration flexible pipe strengthens the soft body of improvement PVC plastics by a chemical fibre and constitutes, described body has an open end at least, wherein, the thickness of the tube wall of described body is less than 2 millimeters, be provided with at least two micropores perpendicular to tube wall in the described tube wall, the length of described micropore is greater than width, described micropore is evenly distributed at interval, in the outside of described tube wall, be coated with one deck nano lamellar silver series inorganic antibiosis coating.
Further, the inboard of described tube wall is coated with one deck nano lamellar silver series inorganic antibiosis coating.
Further, the length direction of described micropore is parallel to the axial of described body.
Further, the length direction of described micropore perpendicular to described body axially.
Principle of work of the present utility model is: body is soft structure, but bulging when aeration and when aeration not, be crushed by the hydrostaticpressure effect, help avoid mud and enter body, the micropore on pipe week footpath surface can aeration, when air pressure increases, micro-pore diameter increases, diameter in can in water, producing respectively, or bubble diameter is less than little diameter bubble of 3mm, bobble rise velocity is slow, gas distribution is even, the oxygen utilization rate height, simultaneously, the thickness of tube wall is less than 2 millimeters, make air flue short straight, atmospheric pressure lost is little, save energy, the nano lamellar silver series inorganic antibiosis coating on body surface can make the body smooth surface, be difficult for the sessile organism film, nano lamellar silver series inorganic antibiosis coating discharges micro silver ion simultaneously, when silver ions arrives the microorganism cells film, because of the latter electronegative, rely on coulombic force, both are firmly adsorbed, silver ions penetration cell wall enters in the cell, and react with sulfydryl, make protein coagulating, destroy the activity of cell synthetic enzyme, cell is lost the division growth ability and death, thereby stop microorganic adhesion to form microbial film, keep airway patency on the body surface.
The utility model and prior art contrast, and its effect is actively with tangible.Diameter or bubble diameter made air flue short straight less than little diameter bubble of 3mm during the utility model can produce respectively, and atmospheric pressure lost is little, save energy, the nano lamellar silver series inorganic antibiosis coating on body surface can make the body smooth surface, is difficult for the sessile organism film, keeps airway patency.
