Description
Technical field
The utility model relates to a kind of jet aerator, is specifically a kind of jet aerator for the sewage aerobic biological treatment, belongs to technical field of sewage treatment equipment.
Background technology
Aerating apparatus is the key equipment that the organic waste water aerobe is processed, and effect and cost that the organic waste water aerobe is processed depend primarily on the aeration effect.
It is the first-selected technique of municipal effluent, sanitary sewage, low-concentration industrial treatment of Organic Wastewater that aerobe is processed, at present aeration mode divides two kinds of mechanical aeration and blast aerations, mechanical aeration is that other mechanical means are sent into air in water by mechanism, as turn brush, inverted umbrella shaped impeller etc., the mechanical aeration operating maintenance is convenient, but energy consumption is all higher; Blast aeration is the pressurized air that aerating apparatus is sent gas blower here, is divided into tiny bubble and sends in water, as micro-hole aerator, jet aerator etc.Micro-hole aerator is energy-conservation, and OTR, utilization ratio are high, but easily stop up, not easy-maintaining.The jet aerator maintenance rate is lower, but energy consumption is higher, and coefficient of oxygen utilization is lower.
Summary of the invention
The utility model purpose is to overcome the defective of above-mentioned aerating apparatus, provides that a kind of coefficient of oxygen utilization is high, energy consumption is low, reliable operation, maintenance rate are lower, the adjustable Gas feeding aerator of air capacity.
The utility model is achieved through the following technical solutions:
Jet aerator, its special feature is to comprise mixing wastewater with air chamber 3, be arranged on mixing wastewater with air chamber one end and part stretches into recirculated water nozzle 2 in the mixing wastewater with air chamber, an end on recirculated water nozzle 2 is provided with water inlet pipe 1, the other end is provided with jet orifice 6, the jet orifice sectional area is less than the water-in sectional area, the other end of mixing wastewater with air chamber is provided with gas-water mixture nozzle 4, and the top of mixing wastewater with air chamber is provided with inlet pipe 5.
Recirculated water in described recirculated water nozzle 2 flow velocity at the jet orifice place after transformation can reach 15-19m/s, sewage is fully mixed, the formation dissolved air water with air.
On described water-in 1, inlet mouth 5, flange is installed all, convenience is connected with pipeline.
All parts materials are carbon steel or stainless steel.
The utility model principle of work:
Changing by employing the mode that the recirculated water nozzle diminishes flows out at a high speed the sewage of recirculated water nozzle ejection, fully mix with gas mixing wastewater with air is indoor, form dissolved air water, spray at a high speed through the gas-water mixture nozzle again, fully mix with sewage in the pond, and the mud in Aerobic Pond can be smashed, strengthen mud and sewage, compressed-air actuated contact area, improve the sludge concentration of Aerobic Pond.Air can be adjusted as required, and mode of connection adopts flange form to connect, and installs simple.
Advantage of the present utility model:
(1) oxygen conversion, utilization ratio are high, energy-conservation.
(2) air quantity is adjusted size by blower fan (frequency conversion) as required, and blower fan can be stopped transport in case of necessity, and the jetted self-priming operation reduces power consumption.
(3) reliable operation can not stopped up, and maintenance load is few.
(4) sewage aerobic processing volume load is high, can greatly reduce the aeration tank volume, reduce cost.
(5) connect the employing flange form and connect, install simple.
Description of drawings
Fig. 1: be the utility model structural representation;
In figure: 1. water inlet pipe, 2. recirculated water nozzle, 3. mixing wastewater with air chamber, 4. gas-water mixture nozzle, 5. inlet pipe, 6. jet orifice.
Embodiment
Referring to accompanying drawing, provide embodiment of the present utility model, be used for formation of the present utility model is further illustrated.
The jet aerator of the present embodiment, comprise mixing wastewater with air chamber 3, be arranged on mixing wastewater with air chamber one end and part and stretch into recirculated water nozzle 2 in the mixing wastewater with air chamber, an end on recirculated water nozzle 2 is provided with water inlet pipe 1, the other end is provided with jet orifice 6, the jet orifice sectional area is less than the water-in sectional area, recirculated water reaches 17-19m/s at the flow velocity at jet orifice place, and sewage is fully mixed with pressurized air, forms dissolved air water.The other end of mixing wastewater with air chamber is provided with gas-water mixture nozzle 4, and the top of mixing wastewater with air chamber is provided with inlet pipe 5.All parts materials are carbon steel.
On water-in 1, inlet mouth 5, flange is installed all, convenience is connected with pipeline.
The jet aerator of the present embodiment, after recirculated water nozzle 2 is diminished, the pressurized air that recirculated water provides from the 2 high speeds ejections of recirculated water nozzle and inlet pipe 5 gas blowers through water inlet pipe 1 mixes mixing section 3 is interior, atomizing, and then gas-water mixture sprays into water from nozzle 4 high speeds.
Gas blower can be realized the air quantity adjustment by frequency conversion, adjusts at any time as required size, and the blower fan of even stopping transport reaches energy-conservation purpose.Jet aerator sprays the air horizontal direction at a high speed at the bottom, and the mud in sewage lagoon is smashed, and increases the contact area of air and sewage and mud, surging force ambassador's air working line in water is long, transformation efficiency and the utilization ratio of oxygen are high, reduce energy consumption, and cost of sewage disposal is low.The jet aerator service area is large, and aerator quantity greatly reduces, and has both reduced maintenance load, again reduce cost.
