Abstract
The utility model discloses a microporous aeration device which comprises a gas inlet pipe (1), an air distributor (2), aeration branch pipes (3) and a variable-hole aeration hose (6), wherein the gas inlet pipe (1) is communicated with the air distributor (2); multiple aeration branch pipes (3) are arranged on the air distributor (2); multiple aeration holes (4) are uniformly distributed in the axial direction and radial direction of each aeration branch pipe (3); two sealing rubber strips (5) are arranged on the two sides of each aeration branch pipe (3); the two sealing rubber strips (5) on the two sides of the aeration branch pipe (3) are sleeved with the variable-hole aeration hose (6); multiple micro-notches (7) are uniformly distributed in the axial direction of the variable-hole aeration hose (6). The microporous aeration device disclosed by the utility model sinks to below the deck surface so that the water sealing effect is guaranteed and the deck space can be effectively saved.
Description
Technical field
The utility model relates to a kind of microporous aeration device.
Background technology
Aeration efficiency is one of important factor of weighing sewage treatment unit performance, is also the key index that determines that can its water quality treatment up to standard, and aeration efficiency is oxygenation capacity, coefficient of oxygen utilization and oxygen transfer efficiency.Oxygen and sewage are short duration of contact, and aeration effect reduces, and the mass transfer rate of oxygen reduces, the molten rate of oxygen reduces, the utilising efficiency of oxygen decreases with the biomembranous effect that contacts with aerobic bacteria, on the one hand, oxygen adsorption effect is for the breeding of aerobic bacteria, and is biomembranously formed with very large effect.If oxygen concn is low, suppress the breeding of aerobic bacteria, thereby aerobic bacteria is just few, the microbial film of formation is just few, and the organism that it is cleared up is just few, same organic content, the time of decomposition is just long.
Summary of the invention
In order to address the above problem, the utility model provides a kind of microporous aeration device, and it is sink to below deck surface, when guaranteeing watertight effect, can also effectively save tween decks.
The utility model has adopted following technical scheme: a kind of microporous aeration device, it comprises inlet pipe, air distributor, aeration branch pipe and variable orifice aeration flexible pipe, described inlet pipe and air distributor are communicated with, on air distributor, be provided with some aeration branch pipes, axial and the some solarization air caps of radial equipartition of each aeration branch pipe, the both sides of each aeration branch pipe arrange two joint strips, described variable orifice aeration flexible pipe is sleeved on two joint strips of aeration branch pipe both sides, axial uniform some micro-incisions of described variable orifice aeration flexible pipe.
Described variable orifice aeration flexible pipe binds on joint strip by anchor ear.
The utlity model has following beneficial effect: the utility model adopts efficient multi-C stereo variable orifice aerating system to carry out oxygenation, less than traditional aerating apparatus aeration resistance and aeration loss; Liquid-gas interface area is increased, and gas-to-liquid contact is wider, and the stirring to water is conducive to the lifting with dynamic efficiency that makes full use of of oxygen; Bubble contact phase area is larger, contact better effects if, and the mass-transfer efficiency of oxygen is higher.The aeration efficiency ratio tradition aeration efficiency of this aerating system is high, has reduced the biochemical time, and treatment effect and speed, far away higher than conventional equipment, meanwhile, have automatic shutter function like this; Thoroughly solved the blockage problem of aerating apparatus.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model aeration branch pipe.
Embodiment
As shown in Figures 1 and 2, the utility model is a kind of microporous aeration device, it comprises inlet pipe 1, air distributor 2, aeration branch pipe 3 and variable orifice aeration flexible pipe 6, described inlet pipe 1 and air distributor 2 are communicated with, on air distributor 2, be provided with some aeration branch pipes 3, axial and the some solarization air caps 4 of radial equipartition of each aeration branch pipe 3, the both sides of each aeration branch pipe 3 arrange two joint strips 5, described variable orifice aeration flexible pipe 6 is sleeved on two joint strips 5 of aeration branch pipe 3 both sides, axial uniform some micro-incisions 7 of described variable orifice aeration flexible pipe 6; Described variable orifice aeration flexible pipe 6 binds on joint strip 5 by anchor ear.
The utility model is placed in the bottom position that leans on of sewage treatment unit, during logical pressurized air, variable aeration flexible pipe 6 pressurized spreadings, micro-incision opens thereupon, and bubble overflows, thereby the bubble forming is little, quantity is many, density is large, be conducive to the lifting with dynamic efficiency that makes full use of of oxygen, while stopping air feed, variable aeration flexible pipe 6 is replied normalities, micro-incision is closed, the obstruction of stopping bottom of device mud.
Claims (2)
1. a microporous aeration device, it is characterized in that it comprises inlet pipe (1), air distributor (2), aeration branch pipe (3) and variable orifice aeration flexible pipe (6), described inlet pipe (1) and air distributor (2) are communicated with, on air distributor (2), be provided with some aeration branch pipes (3), axial and the some solarization air caps of radial equipartition (4) of each aeration branch pipe (3), the both sides of each aeration branch pipe (3) arrange two joint strips (5), described variable orifice aeration flexible pipe (6) is sleeved on two joint strips (5) of aeration branch pipe (3) both sides, axial uniform some micro-incisions (7) of described variable orifice aeration flexible pipe (6).
