Abstract
The invention 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 present invention relates to the device being filled with air in waste water used in a kind of biological process of wastewater treatment, particularly a kind of spiral vortex efflux aerator.
Background technology
In order to the Sustainable development of China's economy and society, how to solve ecological damage that industrial development brings to China and environmental pollution becomes a hot issue.For the process of city domestic sewage and industrial organic waste water, present stage mainly adopts aerobic treatment technology.Blast aeration is exactly become many tiny bubbles to be mixed into technology in water the air dispersion that gas blower is sent here by aerating apparatus, and the treatment effect of waste disposal plant, efficiency and cost often depend on the aeration effect of aerator.Traditional efflux aerator also exists air, sewage mixed effect is not good, and oxygenation capacity is not ideal enough, jet boundary area away poor performance, the shortcoming that service area is little, and this is the major issue needing in a lot of sewage treatment project to solve.
Summary of the invention
The present invention, 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.Jet-flow aeration can be carried out under water to water body.The scope that air injects water body is large, can make air, sewage fully mixes, pond bottom sediments mud and produce the efflux aerator of anaerobic reaction when can prevent sewage disposal.
The present invention is realized by following measures:
A kind of spiral vortex efflux aerator, is characterized in that: comprise spiral distributing water room, primary nozzle, spiral plenum chamber and the coaxial level of secondary nozzle and be socketed successively; On spiral distributing water room, side is vertically installed with eccentric water inlet pipe, and its inwall tangentially position connects spiral distributing water room inwall, 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 tangentially position connects spiral plenum chamber inwall, 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 5:6 to 1:2.
The invention has the beneficial effects as follows and adopt eccentric water inlet without friction screw to reduce energy expenditure, adopt spiral water inlet to form a high efficiency turbulent mixing district with spirally inlet air, its oxygenation capacity is considerably beyond general efflux aerator; The gas-water ratio of device can be made to bring up to 3:1 to 4:1 from 2:1 to 3:1, and the taking of secondary jet wraps up in Entraining Effect makes its inductive flow can reach 5 times of the jet water yield; Save power source, long service life, and reduce sewage aerobic biological treatment cost.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is explained.
As Figure 1-4, be structural representation of the present invention.
The present embodiment is a kind of spiral vortex efflux aerator, comprises the coaxial level of spiral distributing water room 2, primary nozzle 3, spiral plenum chamber 5 and secondary nozzle 6 and is socketed successively; On spiral distributing water room 2, 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 stream-like water body, accelerate to enter in spiral plenum chamber 5 by primary nozzle 3; 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 stream-like 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 enhance entrainment, cut, disperse, the ability of dissolved oxygen, the oxygen accelerated in air dissolves in sewage, is sprayed after forming liquid-vapor mixture by secondary nozzle 6.
Gas tangentially enters spiral plenum chamber 5 vertically downward by eccentric inlet pipe 4, and then in spiral plenum chamber 5, form spiral vortex stream-like gas, the spiral vortex water body sprayed with primary nozzle 3 mixes mutually, 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 the need to adding air filter unit or air pressurized equipment.And spiral vortex stream-like water body adds the turbulent flow cutting intensity in secondary nozzle 6, what the air bubble be filled with in liquid-vapor mixture was cut is finer and closely woven, after secondary nozzle 6 sprays, there is higher jet velocity and certain speed of rotation, extremely strong taking is had to wrap up in Entraining Effect, there is the action of turbulent flow of secondary, make the oxygen in micro-bubble be dissolved in sewage to greatest extent, thus the service face of this aerating apparatus utilization ratio that is larger, oxygen is higher, oxidation effect is better.
Of the present invention be more suitable for dark pond 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 blocking of aerating apparatus; And to blower fan wide adaptability, without the need to adding air filter unit and air pressurized equipment; Without the need to special maintenance in using, have the continuous maneuverability of overlength in non-maintaining situation, under normal service condition, described aerating apparatus has the work-ing life more than 15-20.
