From 1.5 meters of depth of water, task performance is just significantly for Pneumatic water pump pipe assembly.When operating depth is at 2.0 meters or so, penetrate
When stream or aeration, the similar equipment that can be compared is more.Operating depth reaches 4.0 meters, when jet or aeration, and what is can compared similar sets
Standby only aeration head, low pressure Gas feeding jet-flow aeration piping, Cole front yard jet aerator.Under the conditions of flooding, equal power consumption is single
In the time of position, Pneumatic water pump pipe assembly plug-flow aeration running parameter compares following technological layer data with similar device parameter：1、
Enter water air total amount, with aeration head to compare and check object；2nd, the specification and total amount of micro air bubble are formed, in 2.0 meters of operating depths,
With self-priming jet pump to compare and check object；It is right to compare and check with low pressure Gas feeding jet-flow aeration piping when operating depth reaches 4.0 meters
As；3rd, injection flow and speed, typically with pump performance index as reference, when operating depth reaches 4.0 meters, with low pressure Gas feeding
Jet-flow aeration piping, Cole front yard jet aerator are to compare and check object.
Gas retention of excessive fluid plug-flow aeration pipe pier compares principle and parameter with air supply jet aerator：
1st, air demand with draw displacement（Gas-water ratio）：
When operating depth reaches 4.0 meters, the only low pressure supply being similar to gas retention of excessive fluid plug-flow aeration pipe pier working condition
Formula jet-flow aeration piping, Cole front yard jet aerator both Gas feeding jet apparatus.U.S.'s low pressure air supply jet aerator
Gas-water ratio about 2：1；It is a little 4 that German Cole front yard jet aerator gas-water ratio is typically designed:1 or so, Cole front yard jet aerator
Optimal working point occur in gas-water ratio for 2.5:When 1；The flow stream pressure demand of Cole front yard jet aerator is just that low pressure is supplied
2 times of gas formula jet aerator.It can be seen that, the jet apparatus principle of both Gas feedings is similar, only gas-water ratio and liquid stream
Pressure is had any different.They are neither a kind of bubble diffusing apparatus, nor a kind of mechanical aeration equipment, but a kind of composite type is penetrated
Stream aerator.Using air supply jet aerator clear water oxygenation capacity test device, low pressure air supply jet aerator is entered
Row clear water oxygenation capacity is studied.Clean water experiment shows：Low pressure air supply jet aerator coefficient of oxygen utilization is up to 16.34%；Theory is dynamic
Force efficiency is up to 2.65～3.05kgO2/kW.h.Better than the aerator of other forms, can effective reducing energy consumption.Gas retention of excessive fluid plug-flow
With air with pressure as working media, spout flows out the bubble population liquid stream of different size to aeration pipe pier, is similar to U.S.'s low pressure Gas feeding
The working condition of jet-flow aeration piping and German Cole front yard jet aerator both jet-flow aeration equipment.Gas retention of excessive fluid jet-flow aeration
Pipe pier has a hydraulic shear aeration performance with them, but the close ejector pump of main performance, it is air stripping water pump class.Gas retention of excessive fluid plug-flow
The gas-water ratio of aeration pipe pier changes with the intensification of the depth of water, the depth of water at 2.0 meters, gas-water ratio 1:2, when the depth of water reaches 4.0 meters, gas
Water ratio actually reaches 1:3（Nominal number, guards value）.Gas-water ratio diminishes with the increase of the depth of water.When the depth of water is certain, each is marked
The air demand of distribution retention of excessive fluid plug-flow aeration pipe pier 50% time 30% scope can be adjusted in the data for arranging, but gas-water ratio is conservative
Value 1:3（Nominal number）It is constant.Because the dynamic efficiency of jet-flow aeration equipment can be reduced as gas-water ratio increases, in mixing larynx
Gas-liquid maximum contact area is reached in pipe, gas liquid ratio is preferably 1:1, oxygen transfer efficiency and power efficiency of oxygen supply are in optimal shape
State.In the case of gas-liquid maximum contact area identical, if gas volume is less than water body volume（Gas-water ratio is little）, then gas is improved
Effective shock momentum of liquid fluid, the bubble that hydraulic shear is formed is less, and has enough for the water body volume of bubble diffusion.From
Upper to understand, gas retention of excessive fluid jet-flow aeration pipe pier is better than the aerator of all other form, more effective reducing energy consumption.Oxygen demand is
Determined according to the number of the water yield, if water yield variation coefficient is 1.3 or so.The oxygenation capacity of conventional jet device is to disclosure satisfy that
The amplitude of variation of aeration tank dissolved oxygen (1.5-2.8mg/l).When water quality and quantity amplitude of variation is larger, conventional jet device is just difficult
To meet, here it is conventional jet device is difficult the shortcoming for adjusting oxygen.Because oxygenation capacity is a constant volume type.Reduce suction hole electricity
Consumption wastes big, if not running water pump, loses stirring action, makes sludge produce precipitation.Gas retention of excessive fluid plug-flow aeration pipe pier is adjusted
Section air inflow can adjust gas retention of excessive fluid and draw discharge capacity, design minimum air inflow, and adjusting air inflow according to the increase of water quality and quantity can
Discharge capacity is drawn to change gas retention of excessive fluid, the larger situation of water quality and quantity amplitude of variation is adapted to.Compared with all aerators, gas retention of excessive fluid plug-flow
Aeration pipe pier can be placed in deeper water, have higher stirring action than aerator, and without complicated placement process.
Very big if necessary to the area of aeration, it is just more suitable, the multidirectional installation of energy multiple spot, forms oxygen supplement fluidised form flow field, area coverage
Big cost is little.
2nd, the specification and total amount of different bubbles：
When gas retention of excessive fluid plug-flow aeration pipe pier operating depth reaches 4.0 meters, gas-vapor mix fluid is with about 0.6～0.8 meter per second
Speed horizontal-jet, constitutes horizontal plug-flow, reaches jet-flow aeration（Pump）The efficiency of machine.The conservative value of gas-water ratio is up to 1:3
（34%）.
3rd, spout flow velocity and plug-flow distance：
In 2.0 meters of operating depths, the speed of the meter per second of gas retention of excessive fluid plug-flow aeration pipe pier spout flow velocity 0.4～0.5（Jet flow
Measure when cause for gossip is tested）, about 2.0 meters of plug-flow distance（Actual measurement）.When operating depth reaches 4.0 meters, gas retention of excessive fluid plug-flow aeration pipe pier
The speed of the meter per second of spout flow velocity 0.6～0.8, about 3.0 meters of plug-flow distance（Estimation）.
Gas retention of excessive fluid plug-flow aeration pipe pier is compared with air supply jet aerator and calculates data：
It is known：1st, the Technique performance parameter of Roots's air pump and water pump, when operating depth reaches 4.0 meters, Roots's air pump
Air demand is 40m3/ kwh.The capacity of water supply of water pump is 10～15m3/ kwh.2nd, U.S.'s low pressure Gas feeding jet-flow aeration
The gas-water ratio of device about 2:1；When air demand is 40m3/ h, correspondence output 20m3/ h..From Roots's air pump and the technology of water pump
Knowable to performance parameter, add up to 2 kwh of power consumption.3rd, when operating depth reaches 4.0 meters, compare U.S.'s low pressure Gas feeding jet and expose
The gas-water ratio of gas device about 2:1, the air demand of gas retention of excessive fluid plug-flow aeration pipe pier with draw displacement（Gas-water ratio）Actually reach 1:3
（Fixed number, guards value）, when in 4.0 meters of operating depths, when the air demand of Roots's air pump is 40m3/h., consume energy 1kwh, gas
Retention of excessive fluid plug-flow aeration pipe pier draws displacement and reaches 120m3/ h.Save water pump energy consumption 1kwh., more than jet flow water yield 100m3/
h.The gas-water ratio for comparing German Cole front yard jet aerator is typically designed a little as 4:When 1, spray more than gas retention of excessive fluid plug-flow aeration pipe pier
Streamflow 110m3/ h.4th, because the dynamic efficiency of Gas feeding jet apparatus can be reduced as gas-water ratio increases, in mixing larynx
Gas-liquid maximum contact area is reached in pipe, gas liquid ratio is preferably 1:1, oxygen transfer efficiency and power efficiency of oxygen supply are in optimal shape
State.In the case of gas-liquid maximum contact area identical, if gas volume is less than water body volume（Gas-water ratio is little）, then gas is improved
Effective shock momentum of liquid fluid, there is enough bubble diffusion water body volumes, and the bubble that hydraulic shear is formed is less.Thus may be used
Know, when operating depth is to 4.0 meters, the gas-water ratio of gas retention of excessive fluid plug-flow aeration pipe pier is 1:3（34%）, better than Gas feeding jet
Aerator, more effective reducing energy consumption.
