Novel high-efficient air supporting releaser

Technical Field

The invention belongs to the technical field of pressure dissolved air floatation equipment, and particularly relates to a novel efficient air floatation releaser.

Background

The pressure dissolved air floatation water purification method is a new water treatment technology, and is widely applied in China and many advanced industrial countries. The new water purifying method is to introduce great amount of fine bubbles released from pressure dissolved air into water to be treated and utilize the buoyancy of bubbles adhered to solid impurity to separate solid from liquid fast and raise the concentration degree of floating slag. The dissolved air releaser is a key device in a pressure dissolved air flotation water purification system. The pressure dissolved air water can release a large amount of micro-bubbles only after the pressure is reduced and the energy is dissipated through the device, the performance of the releaser relates to the amount of the released bubbles, the fineness of the bubbles, the distribution law of the sizes of the bubbles and the like, and the pressure dissolved air water directly influences the water purifying effect of the air floatation method and the consumption of electric energy. The existing air-float releaser is easy to block, the distribution uniformity of the pressure dissolved air water of the releaser is poor during working, the released air bubbles are uneven or have larger sizes, the probability of collision and adhesion of the air bubbles and impurities is reduced, and the water purification effect is not ideal. Accordingly, there is a need for improvements to existing releases.

The invention will be described in detail with reference to the following embodiments with reference to the attached drawings.

A novel high-efficiency air-float releaser, as shown in figures 1 to 3,

comprises a base 2 with a first cavity 1 and an outer cover 4 with a second cavity 3; after the outer cover is connected with the base, an inner cavity of the releaser assembly is formed inside the outer cover and the base;

the base is provided with a dissolved air water inlet 5 communicated with the inner cavity of the releaser; a plurality of air distribution holes 6 are formed in the side wall of the outer cover;

a flower disc 7 is arranged in the inner cavity of the releaser assembly and close to one side of the dissolved air water inlet, a floating plate 8 is arranged on one side of the flower disc, which is different from the dissolved air water inlet of the base, and a rubber ring 9 is arranged between the flower disc and the floating plate; through the rubber ring, separate flower disc and kickboard, avoid direct the falling of kickboard on the flower disc after the stop work, the condition that is difficult to open after kickboard and flower disc corrosion bonding together. Generally, the distance between the rubber ring and the bottom surface of the base is greater than the thickness of the flower disc, and the distance between the rubber ring and the top surface of the outer cover is greater than the thickness of the floating plate, so that the flower disc and the floating plate can float in the inner cavity of the releaser.

The kickboard middle part is equipped with centre bore 10 be equipped with a plurality of via holes 11 on the flower disc, the via hole on the flower disc sets up with flower disc center equipartition, and each via hole all with the centre bore of kickboard and each via hole and dissolved air water import, all do not have the overlap. When the pressure gas-dissolving water enters the gas-dissolving water inlet, the pressure gas-dissolving water firstly pushes the flower disc open, the water-steam mixture passes through the through holes of the flower disc and then pushes the floating plate open, and after the floating plate passes through the gas distribution hole, water flow is sprayed out from the gas distribution holes.

The rubber ring is fixed on the inner wall of the second concave cavity or the inner wall of the first concave cavity. Usually, a groove for installing the rubber ring is arranged on the inner wall of the second concave cavity or the inner wall of the first concave cavity, and of course, the rubber ring can be fixed by gluing or other fixing methods.

The outer cover is fixedly connected with the base through threads. For example, the base is provided with an external thread structure 12, and the outer cover is provided with an internal thread structure 13 matched with the external thread structure.

The air distribution holes are uniformly distributed on the outer cover. Preferably, each air distribution hole is uniformly distributed by taking the axis of the central shaft of the outer cover as the center. The central hole is arranged in the middle of the floating plate, so that when the floating plate stops working, the floating plate is guaranteed to fall smoothly, gas can be discharged upwards through the central hole, the gas cannot be blocked in the inner cavity of the releaser assembly, the floating plate is guaranteed to be closed in place, and water return is prevented. When the work is stopped, the flower disc falls on the bottom of the base, the floating plate is attached to the upper edge of the rubber ring after falling, and the through holes in the flower disc are not overlapped with the gas-dissolved water inlet, so that the inner cavity of the releaser assembly is not communicated with the gas-dissolved water inlet, and the water return is effectively avoided.

It is pointed out that the compressed air and the compressed water dissolve a large amount of air in the water through mass transfer, diffusion and dissolution processes in the pressure vessel to form pressure dissolved gas water. The pressure gas-dissolving water enters the releaser assembly for instantaneous pressure reduction, energy dissipation, mass transfer and gas release. According to henry's law, the saturated solubility of air in water is proportional to the pressure in the container, and as the pressure decreases, the gas dissolved in the water is instantaneously released.

The working principle of the air floatation releaser provided by the invention is as follows: after pressure dissolved air water is introduced into a dissolved air water inlet, because a water-vapor mixture is blocked by the center of the flower disc, the flower disc can be jacked open firstly, then the side of the flower disc is drained through a via hole arranged, water and gas are distributed, and a floating plate positioned on the flower disc is jacked up through high-pressure water power, and the jacked floating plate is extruded due to the impact of the water power, vibration water waves can be continuously generated, the inner cavity of a releaser assembly generates turbulent flow, after the pressure dissolved air water in the inner cavity is irregularly cut, a large amount of micro-fine bubbles are released through a gas distribution hole in the side wall of the outer cover of the cylindrical shape, the micro-fine bubbles collide and adhere with impurities in the wastewater to be treated, and therefore the impurities in the water are.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the invention, so that any modifications, equivalents, improvements and the like, which are within the spirit and principle of the present invention, should be included in the scope of the present invention.
