Description
Technical field
The present invention relates to the Aerobic biological process facility technology fields of sewage treatment, in particular to modified Gas feeding low pressure
Jet aerator.
Background technique
Aerobic biological process is the main process of sanitary sewage and Industrial Wastewater Treatment, it has high treating effect, operation
The advantages that at low cost.Aerator is mainly supplied oxygen into water in Aerobic Process for Treatment system, keeps the oxygen in air effective
Ground is dissolved into unsaturated water body, to maintain growth and the biological oxidation of microorganism；It is mixed by the stirring of aerator
Cooperation is used, and making the activated sludge in water body is in suspended state, and the oxygen in organic matter, microorganism and water can be contacted adequately, is
The removal of organic matter and the growth of microorganism create advantageous condition；Aerator has motive force to water flow, keeps muddy water mixed
It closes object to circulate in aeration tank, promotes oxygen being uniformly distributed in water body.Aerating system is as sewage treatment plant simultaneously
Core cell, energy consumption accounts for about the 45%~75% of entire sewage treatment plant's energy consumption.Therefore the high aeration of research oxygenation capacity is set
For for the energy-saving significant of sewage treatment plant.
It can be substantially divided into three categories using more aerator at present: diffused air aeration device, mechanical aerator, jet stream
Aerator.And wherein jet aerator is therefore widely used in aerobe because having oxygenation and plug-flow effect concurrently to sewage
In treatment process.Improved Gas feeding low pressure stream aerator by air blower force by air blast in aerator with solid-liquid
Mixed phase is mixed, and oxygen transfer efficiency reaches 30%-35%, while low to the lift demand of water circulating pump, and dynamic efficiency
Up to 4.0-5.2kg/ (kWh).There is greater advantage compared with Self-priming jet aeration device, and is not easy to plug, it is basic not have to maintenance,
Sludge concentration can be higher, and it is without secondary pollution not will cause winged mist, all advantageous compared with micro-hole aerator and mechanical aeration.Due to
Oxygen-transfer efficiency is low, and the mixed effect of gas and water is poor.
Summary of the invention
In order to further increase the oxygen transfer efficiency and dynamic efficiency of Gas feeding low pressure stream aerator, the purpose of the present invention
It is to make the air being passed through in sewage, activated sludge and air inlet pipe carry out coming into full contact with mixing by improving the structure in aerator,
To improve the oxygen transfer efficiency and dynamic efficiency of aerator.
To achieve the goals above, the technical solution adopted by the present invention is that:
Modified Gas feeding low pressure stream aerator, including mixing chamber 5, the mixing chamber 5 are internally provided with spherical gas
Liquid mixed cell 3, spherical mixed cell 3 are connected with air inlet pipe 4 and are set to 2 front end of first order jet nozzle, and air inlet pipe 4 is located at spherical mixed
3 top of unit is closed, hole 7 or setting escape pipe 8 is opened up away from side at first order jet nozzle 2 in spherical mixed cell 3, is located at outlet
Secondary nozzle 6 is provided at the mixing chamber 5 of 8 front end of pipe, the first order jet nozzle 2 is arranged on circulating water pipe 1.
3 sectional area of spherical mixed cell accounts for the 30%-50% of 5 sectional area of mixing chamber.
The spherical gas-liquid mixed unit 3 is arranged at 2 front end 5-10cm of first order jet nozzle, inside spherical mixed cell 3
Central point and 2 center of first order jet nozzle are in same level height.
The 7 maximal projection area of hole accounts for the 20%-50% of spherical 3 maximum secting area of mixed cell, and escape pipe 8 is long
1-4cm is spent, 8 area of escape pipe accounts for the 20%-50% of spherical 4 maximum secting area of mixed cell.
Beneficial effects of the present invention:
With being now applied in Practical Project compared with Gas feeding low pressure stream aerator, this practical invention can be by sewage, activity
The gas-liquid-solid mixed phase of sludge and air better disperses mixing, while increasing the turbulence intensity in mixing chamber, and air is broken up
For micro-bubble, increase gas liquid interfacial area more rapidly soluble in gas-liquid mixed phase, to improve the oxygen transfer effect of aerator
Rate and dynamic efficiency achieve the effect that energy-saving.
