Description
Technical field
A kind of low pressure oxygenation of the utility model sparging unit belongs to the injector technical field, specially refers to a kind of WWT oxygenation sparging unit.
Background technology
Traditional AA/O method biological denitrificaion engineering of disposing of sewage mainly is made up of anaerobic pond, anoxic pond and Aerobic Pond; Aerobic Pond aeration wherein; Lay aeration tube, aeration head oxygen charging method at the bottom of adopting the pond,, reach and support the required oxygen concentration of bacterium to reach the Aerobic Pond oxygen content.Because the bubble that produced of this kind aeration mode all is an air pocket, the oxygen level of Aerobic Pond can not reach requirement at short notice, so that Aerobic Pond is done is all bigger, aeration tube and aeration head are all more.
It mainly is to form negative pressure through impeller pump to injector injection pressure water generates jet to suck the air pond oxygen supply of anhydrating jointly from suction opening that new in recent years jet Aeration Technology and Its is handled trade effluent, and this method sucks air capacity and receives the influence of water-aspirator pressure very big.Want to strengthen air imbibed quantity, just must increase pump power.This kind method is if select for use the self-priming sparging unit of existing negative pressure to need many ability satisfy the Aerobic Pond oxygen requirement, thus not energy-conservation, and facility investment is big, does not meet industrial production WWT reality.
At present, also having a kind of mode is exactly the mount high power gas blower at the suction opening place, strengthens the soakage of air; But receive the restriction of dissolved oxygen speed and the solubleness etc. of sewage; Cause a big chunk oxygen to fail to have been caused waste, increased cost by dissolution of contaminated water.
The utility model content
A kind of low pressure oxygenation of the utility model sparging unit has overcome the deficiency that prior art exists, provide a kind of simple in structure, operating cost is low, make oxygen and sewage can thorough mixing, the device of raising sewage dissolved oxygen amount.
In order to solve the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of low pressure oxygenation sparging unit, comprise nozzle, gas-liquid mixed chamber, trunnion, diffuser tube, tail pipe, and said nozzle is connected with the gas-liquid mixing section; The gas-liquid mixed chamber is connected with trunnion; Trunnion is connected with diffuser tube, and diffuser tube is connected with tail pipe, and said nozzle, gas-liquid mixed chamber, trunnion, diffuser tube, tail pipe communicate in the junction; Circle distribution has 2～4 inlet pipe on the outer wall of said gas-liquid mixed chamber, and said inlet pipe communicates with the gas-liquid mixed chamber interior.
The outer end of said inlet pipe is equipped with flange, also is provided with pad between said flange and the inlet pipe.
Said tail pipe or be straight tube, or be bend pipe.
The utility model compared with prior art has following beneficial effect:
1, through a plurality of inlet pipe are set, increases the contact site of air and sewage, the contact area of air and sewage is multiplied, made air and sewage thorough mixing, improved the utilization ratio of oxygen.
2, increasing of inlet pipe makes gas-liquid mixed efficient improve, and power-equipments such as external blast apparatus and sewage (waste water) recirculating pump only need adopt low-power equipment, just can reach required effect, have reduced energy consumption, practice thrift cost.
3, under low pressure air and sewage spray simultaneously; Can realize that in jet process energy crosses, violent gas-liquid-solid three-phase mixing phenomena occur, than traditional air pocket oxygenation way; The process that can a large amount of oxygen of instantaneous completion be shifted to liquid phase by gas phase improves the dissolved oxygen amount of unit water area.The raising of dissolved oxygen amount has strengthened the activity of supporting bacterium well, has improved wastewater treatment efficiency, significantly improves environmental protection effect.With compare at the bottom of traditional technology adopts high-power gas blower that air is sent into the pond, reduced cost of investment, reduced energy consumption.
4, because the existence of a plurality of inlet pipe, accelerated mixing of oxygen and sewage, shortened aeration time, save the expense that traditional Aerobic Pond needs big area laying aeration tube, aeration head and other aerators, can reduce floor space.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explanation.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Among the figure: 1 is that nozzle, 2 is that gas-liquid mixed chamber, 3 is that trunnion, 4 is that diffuser tube, 5 is that tail pipe, 6 is that inlet pipe, 7 is a flange.
Embodiment
Like Fig. 1, shown in Figure 2; A kind of low pressure oxygenation of the utility model sparging unit comprises nozzle 1, gas-liquid mixed chamber 2, trunnion 3, diffuser tube 4, tail pipe 5, and said nozzle 1 is connected with gas-liquid mixing section 2; Gas-liquid mixed chamber 2 is connected with trunnion 3; Trunnion 3 is connected with diffuser tube 4, and diffuser tube 4 is connected with tail pipe 5, and said nozzle 1, gas-liquid mixed chamber 2, trunnion 3, diffuser tube 4, tail pipe 5 communicate in the junction; Circle distribution has 2～4 inlet pipe 6 on the outer wall of said gas-liquid mixed chamber 2, and said inlet pipe 6 communicates with 2 inside, gas-liquid mixed chamber.
