Abstract
The invention relates to a water treatment device and provides an improved tray type jet aerator for overcoming the technical defect that the conventional tray type jet aerator is high in energy consumption during working. The improved tray type jet aerator comprises a tray type water inlet cavity and a tray type gas storage cavity buckled with the top of the water inlet cavity, wherein a water inlet pipe is arranged at the bottom of the water inlet cavity, an air inlet pipe is arranged at the top of the gas storage cavity, and a plurality of outward-stretching outer nozzles are arranged at the periphery of the water inlet cavity. The improved tray type jet aerator is characterized in that inner nozzles concentrically sleeved with the outer nozzles are arranged in the outer nozzles, the tails of the inner nozzles are sealed and fixed with the inner walls of the tails of the outer nozzles, gas-liquid mixing cavities are formed in cavities between the inner nozzles and the outer nozzles, air suction inlets are formed in the nozzle walls of the outer nozzles close to nozzle holes of the outer nozzles and are communicated with the gas storage cavity. The improved tray type jet aerator is reasonable in structure and high in oxygen use ratio and can be widely applied to various aeration operations of water treatment.
Description
Technical field
The present invention relates to a kind of water treatment device, be specifically related to indispensable equipment-a kind of improved disc type jet aerator of plumbing oxygenation.
Background technology
The disc type jet aerator is dish-shaped cavity fit by inside and outside two and forms, and two chamber side face correspondences are provided with many group concentric nozzles.Recirculated water is sprayed at a high speed through each nozzle by inner chamber, mix with the exocoel pressure air, utilize jet shear pressure air to form gas-liquid mixture, again through exocoel nozzle second spraying, finish air (oxygen)---mass transfer and the diffusion process of mixed solution, thus reach the purpose of oxygenation in the water.A kind of disc type jet aerator is disclosed as CN201447385U, this aerator, comprise inlet pipe, water inlet pipe, inner chamber, exocoel, inner nozzle, la farr pipe formula outer nozzle, it is characterized in that: la farr pipe disc type jet aerator central part is provided with inner chamber, inner chamber is the cydariform inner chamber of two thes bottom of a pan end face, intracavity bottom connects water inlet pipe, the inner chamber outside is provided with some inner nozzles, the inner chamber outside is provided with one and contains its exocoel, the outside of exocoel is provided with some la farr pipe formula outer nozzles, the la farr pipe formula outer nozzle of the inner nozzle of inner chamber and exocoel is corresponding being connected one by one, and the top of exocoel also is provided with inlet pipe.The oxygen utilization rate when though this aerator external nozzles has adopted Rafael nozzle effectively to improve oxygenation, but its inlet pipe need provide the blast of big pressure that air is blown in the gas-liquid mixed chamber to realize the shearing of air, the inlet pipe outside need provide more powerful blower fan to carry out air pressurized when therefore this plate-type aerator was worked, and its power consumption is bigger.
Summary of the invention
The big technological deficiency of power consumption the invention provides a kind of improved disc type jet aerator when working for overcoming present disc type jet aerator.
The technical solution used in the present invention is: a kind of improved disc type jet aerator, comprise disc type intake antrum and the disc type air storing cavity that fastens with the intake antrum top, the bottom of intake antrum is provided with water inlet pipe, the top of air storing cavity is provided with inlet pipe, periphery at intake antrum is provided with several outward extending outer nozzles, it is characterized in that: the inner nozzle that is provided with suit concentric with it in the described outer nozzle, the afterbody of inner nozzle and outer nozzle afterbody inner wall sealing are fixed, cavity between inner nozzle and the outer nozzle forms the gas-liquid mixed chamber, near the inner nozzle jet hole outer nozzle nozzle wall is offered air suction inlet, and air suction inlet and air storing cavity connect.
This disc type jet aerator adopts said structure, the one, can make the right alignment of outer nozzle and inner nozzle better, water body in the intake antrum forms current in inner nozzle, these current directly inject in the outer nozzle chamber, prevented the technical problem that interior outer nozzle separated flow is interfered between interior outer nozzle, made high velocity flow in the gas-liquid mixed chamber, shear the back to air and form the current that have a large amount of bubbles that these current are directly penetrated by outer nozzle, its powerful effectively improves the aeration effect; The 2nd, take full advantage of near the negative pressuren zone that when current penetrate, forms the inner nozzle, utilize the air in this negative pressuren zone air storing cavity to be sucked in the gas-liquid mixed chamber, the inlet pipe of air storing cavity need not to increase high-power blower air is pressurizeed, and effectively reduces the work energy consumption of aerator.This improved disc type jet aerator is rational in infrastructure, coefficient of oxygen utilization is high, can be widely used in the aeration operation of various water treatments.
Description of drawings
Accompanying drawing 1 is sectional view of the present invention.
Among the figure, 1, intake antrum, 2, air storing cavity, 3, water inlet pipe, 4, inlet pipe, 5, inner nozzle, 6, outer nozzle, 7, the gas-liquid mixed chamber, 8, air suction inlet.
Embodiment
The present invention will be further described below in conjunction with drawings and Examples.
As shown in drawings, a kind of improved disc type jet aerator comprises disc type intake antrum 1 and the disc type air storing cavity 2 that fastens with the intake antrum top, and the bottom of intake antrum is provided with water inlet pipe 3, and the top of air storing cavity is provided with inlet pipe 4.
In following content, will be described in detail wherein an external nozzle 6 and the structure of inner nozzle 5, should be appreciated that each external nozzle 6 and inner nozzle 5 are replicated at the periphery of intake antrum 1, the periphery of intake antrum 1 has been set up some external nozzles 6 and inner nozzle 5.
As shown in drawings, the outer chamber wall of intake antrum is provided with outward extending outer nozzle 6,6 inner nozzles 5 that are provided with suit concentric with it in outer nozzle, the afterbody of inner nozzle 5 and outer nozzle 6 afterbody inner wall sealings are fixed, cavity between inner nozzle 5 and the outer nozzle 6 forms gas-liquid mixed chamber 7, near the inner nozzle jet hole outer nozzle nozzle wall is offered air suction inlet 8, and air suction inlet 8 connects with air storing cavity 2.
During work, have the water body of pressure in water inlet pipe enters intake antrum, high pressure water is penetrated by the inner nozzle with the intake antrum perforation, form High-Pressure Water, near the inner nozzle jet hole, can form a negative pressuren zone, utilize the air in this negative pressure air storing cavity to be sucked in the gas-liquid mixed chamber, form the high velocity flow that is rich in bubble after the high velocity flow that inner nozzle penetrates is sheared air and by the outer nozzle ejaculation outside water body is carried out aeration.
