Abstract
The utility model belongs to a dissolved air releaser of a wide runner. The dissolved air releaser comprises a circular or square shell (1), wherein a plurality of parallel resistance plates (2) are uniformly distributed and fixed at the top end and the inner cavity of the shell (1) and are provided with arced or linear, mansard and wavy outlets (3); outlets (3) of the resistance plates are arranged in a left and right interlacing manner; and the lower end of the shell (1) is provided with a tapered inlet (4). When pressure dissolved air water passes through the dissolved air releaser, the dissolved air releaser of the wide runner disclosed by the utility model is capable of fast and thoroughly reducing pressure and dissipating energy with a reasonable water channel, completely and timely evoluting gas, and generating micro bubbles by combining ultra fine bubbles under a moderate flow state, has the advantages of right bubble size and small shape, and is steady to release, uniform in distribution of gas releasing water, smart in appearance, simple in structure, flexible to arrange and unlikely to block.
Description
Technical field
The utility model belongs to the sewage disposal utensil, particularly a kind of wide runner dissolved air release.
Background technology
Dissolved air release is the key part in pressure air-dissolving air-float water technology gas releasing system, and it reaches the height of the quality of flotation waste water treatment effect and day-to-day operation expense all influential to size, the distribution of bubble.In water technology, this device can discharge intensive micro bubble by the decompression energy dissipating passage by particular design at dissolved gases under pressure, adhere to oil, flco or other particle in water, thereby form the little aggregate of density ratio water, be easy to float up to the water surface, reach two purposes that are separated.Tongji University's series reliever is widely used at present, and wherein TS type reliever is due to the narrow and small easy obstruction in water outlet gap; The output procedure of TJ, TV reliever pressure air-dissolving water, still consistent with traditional design form, namely outgas water is consistent with pressure air-dissolving water input direction, along discharging on the edge plane of dish, is easy to like this form liquid group and makes the outgas water distribution inhomogeneous.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, provides a kind of water outlet be difficult for to stop up, and liquid group makes outgas water distribution a kind of wide runner dissolved air release uniformly.
The technical scheme that the utility model technical solution problem adopts is: a kind of wide runner dissolved air release, comprise circle or square shell, it is characterized in that top and the even fixing a plurality of flaps that are parallel to each other that distribute of inner chamber at shell, flaps is provided with arc or linear pattern, fold-line-shaped, corrugated outlet, each flaps outlet left and right is crisscross arranged, and the shell lower end is provided with conical entrance.
The beneficial effects of the utility model are: when this utility model is passed through when pressure air-dissolving water, it is thorough rapidly that reasonably water stream channel makes the decompression energy dissipating, gas is overflowed fully in time, last ultra-fine bubble and the large micron order bubble that generates carry out under gentle fluidised form, bubble size is suitable, release is stable, make the outgas water distribution even, be difficult for stopping up; Profile is small and exquisite, and is simple in structure, flexible arrangement.
Description of drawings
Illustrate with embodiment below in conjunction with accompanying drawing.
Fig. 1 is a kind of wide runner dissolved air release front view;
Fig. 2 is the A-A sectional view of Fig. 1.
In figure: the 1-shell; The 2-flaps; The 3-outlet; The 4-entrance.
Embodiment
Embodiment, with reference to accompanying drawing, a kind of wide runner dissolved air release, comprise circle or square shell 1, it is characterized in that top and the even fixing a plurality of flaps that are parallel to each other 2 that distribute of inner chamber at shell 1, flaps 2 is provided with arc or linear pattern, fold-line-shaped, corrugated outlet 3, and each flaps outlet 3 left and right are crisscross arranged, and shell 1 lower end is provided with conical entrance 1.When this utility model was passed through when pressure air-dissolving water, it is thorough rapidly that reasonably water stream channel makes the decompression energy dissipating, and gas is overflowed fully timely, last ultra-fine bubble and the large micron order bubble that generates carry out under gentle fluidised form, bubble size is suitable, release is stable, makes the outgas water distribution even, is difficult for stopping up; Profile is small and exquisite, and is simple in structure, flexible arrangement.The material of shell 1 and flaps 1 is all metal or engineering plastics; Outlet 1 is arc, and the slit width of outlet 3 is not less than 2mm.
