Abstract
The utility model discloses a spiral vortex jet-flow aerating device, which is applied in the biological treatment process of wastewater and is used for filling air into the wastewater. The spiral vortex jet-flow aerating device comprises an eccentric water inlet pipe 1, a spiral water distribution chamber 2, a primary nozzle 3, an eccentric air inlet pipe 4, a spiral air distribution chamber 5, a secondary nozzle 6 and the like. Friction-free spiral water supply and spiral air supply methods are adopted, sewage enters the spiral water distribution chamber 2 in the tangent direction to form a spiral vortex water body, low-pressure air enters the spiral air distribution chamber 4 in the tangent direction to form a spiral vortex air body, the air supply amount is increased due to the rotation centrifugal force of the air and fluid mixture, oxygen in tiny bubbles is enabled to dissolve in the sewage to the maximum degree, thus, the aerating device has a larger service area, the use ratio of the oxygen is higher, and the oxygen filling effect is better.
Description
Technical field
The utility model relate in a kind of biological process of wastewater treatment, use to the device that is filled with air in waste water, particularly a kind of spiral vortex efflux aerator.
Background technology
For China's economy and social Sustainable development, how solving ecological damage and the environmental pollution that industrial development brings to China becomes a hot issue.For the processing of city domestic sewage and industrial organic waste water, present stage mainly adopts aerobic treatment technology.Blast aeration is exactly that the air dispersion of gas blower being sent here by aerating apparatus becomes many tiny bubbles to sneak into the technology in water, and the treatment effect of waste disposal plant, efficiency and cost often depend on the aeration effect of aerator.Traditional efflux aerator exists air, sewage mixed effect is not good, and oxygenation capacity is not ideal enough, and jet boundary region promotes poor performance, the shortcoming that service area is little, and this is the major issue that needs solution in a lot of sewage treatment projects.
Summary of the invention
The utility model, in order to solve the problem of aeration inefficiency in environment and During Industrial Wastewater Treatment Process, provides a kind of spiral vortex efflux aerator.Can to water body, carry out jet-flow aeration under water.The scope that air is injected water body is large, can make air, sewage fully mix, the efflux aerator of pond bottom sediments mud and generation anaerobic reaction in the time of can preventing sewage disposal.
The utility model is realized by following measures:
A spiral vortex efflux aerator, is characterized in that: comprise that spiral distributing water room, primary nozzle, spiral plenum chamber and the coaxial level of secondary nozzle are socketed successively; On spiral distributing water room, a side is vertically installed with eccentric water inlet pipe, and its inwall connects spiral distributing water room inwall along tangent position, and sewage tangentially enters spiral distributing water room by eccentric water inlet pipe, forms spiral vortex water body; On spiral plenum chamber, homonymy is vertically installed with eccentric inlet pipe, and its inwall connects spiral plenum chamber inwall along tangent position, and air tangentially enters spiral plenum chamber by eccentric inlet pipe, forms spiral vortex gas; Two spiral vortex fluids and then be thoroughly mixed to form liquid-vapor mixture in spiral plenum chamber.
Described a kind of spiral vortex efflux aerator, is characterized in that: eccentric water inlet pipe width is 1/3 to 1/5 of spiral distributing water room diameter; Eccentric inlet pipe width is 1/3 to 1/5 of spiral plenum chamber diameter; The ratio of primary nozzle top and secondary nozzle top end diameter is between between 5:6 to 1:2.
The beneficial effects of the utility model are to adopt bias to reduce energy expenditure without friction screw water inlet, adopt spiral water inlet and spirally inlet air to form a high efficiency turbulent mixing district, and its oxygenation capacity is considerably beyond general efflux aerator; Can make the gas-water ratio of device bring up to 3:1 to 4:1 from 2:1 to 3:1, the taking of secondary jet wrapped up in and entrainmented effect and make its inductive flow can reach 5 times of the jet water yield; Save power source, long service life, and reduced sewage aerobic biological treatment cost.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is made to specific description.
As Figure 1-4, be structural representation of the present utility model.
The present embodiment is a kind of spiral vortex efflux aerator, comprises that spiral distributing water room 2, primary nozzle 3, spiral plenum chamber 5 and the coaxial level of secondary nozzle 6 are socketed successively; On spiral distributing water room 2, a side is vertically installed with eccentric water inlet pipe 1, be connected with water inlet system, sewage tangentially enters spiral distributing water room 2 vertically downward by described eccentric water inlet pipe 1, and then in spiral distributing water room, form spiral vortex shape water body, by primary nozzle 3, accelerate to enter in spiral plenum chamber 5; On spiral plenum chamber 5, homonymy is vertically installed with eccentric inlet pipe 4, be connected with airing system, gas tangentially enters spiral plenum chamber 5 vertically downward by described eccentric inlet pipe 4, and then in spiral plenum chamber 5, form spiral vortex shape gas, the water body and the gas that are all spiral vortex fully mix in spiral plenum chamber 5, the centrifugal force of high speed rotating strengthened entrainment, the ability of cutting, dispersion, dissolved oxygen, accelerate airborne oxygen and dissolve in sewage, after formation liquid-vapor mixture, by secondary nozzle 6, sprayed.
Gas tangentially enters spiral plenum chamber 5 vertically downward by eccentric inlet pipe 4, and then in spiral plenum chamber 5, form spiral vortex shape gas, mix mutually with the spiral vortex water body of primary nozzle 3 ejections, because spiral vortex water body has certain initial velocity, after mixing, the centrifugal force of liquid-vapor mixture can increase air demand again, therefore this device is to blower fan wide adaptability, without adding air filter unit or air pressurized equipment.And spiral vortex shape water body has increased the turbulent flow cutting intensity in secondary nozzle 6, make cut finer and closely woven of the air bubble that is filled with in liquid-vapor mixture, after secondary nozzle 6 ejections, there is higher jet velocity and certain speed of rotation, there is extremely strong taking to wrap up in and entrainment effect, the action of turbulent flow with secondary, make the oxygen in micro-bubble be dissolved in to greatest extent sewage, thereby the service face of this aerating apparatus utilization ratio larger, oxygen is higher, oxidation effect is better.
Of the present utility modelly be more suitable for dark pond and process, the depth of water is generally 5-14 rice, and in the dark scope in this pond, energy-saving effect is obvious; Bigbore nozzle, makes the more difficult obstruction of aerating apparatus; And to blower fan wide adaptability, without adding air filter unit and air pressurized equipment; In use, without special maintenance, have the continuous maneuverability of overlength in non-maintaining situation, under normal service condition, described aerating apparatus has the work-ing life over 15-20.
