Abstract
The utility model discloses a kind of dissolved air water release system, comprise dissolved air water inlet pipe, dissolved air water hold-up vessel and dissolved air water releasing tube, in dissolved air water release, district arranges described dissolved air water hold-up vessel, dissolved air water inlet pipe described in tank skin one side joint of described dissolved air water hold-up vessel, relative opposite side is positioned at bottom air flotation pool dissolved air water release district and connects described dissolved air water releasing tube; By installing the air flotation pool of this kind of dissolved air water release system, mud solid content after process is increased to 4.5% from 2.2%, produce mud volume and be about reduced to original 1/2nd, more be conducive to follow-up centrifugal dehydration treatment, the backwater of air supporting simultaneously COD is reduced to 350mg/L from 900mg/L, and can ensure stable continuous service effect, the technique adjustment frequency and working strength decline to a great extent, reach floatation thickening optimum regime completely and mud solid carbon dioxide is clear.
Description
Technical field
The utility model belongs to drainage system air flotation technology field, is specifically related to a kind of dissolved air water release system.
Background technology
Extensively adopt gas-liquid polyphase flow pump to be applied in air-float technology in recent years, air dissolved pump sucks air at feed-water end, utilizes special impeller in pump repeatedly to cut, and reaches molten gas object in pump, is delivered in air flotation pool by dissolved air water by pipeline.At present, dissolved air water release system generally adopts straight tube, does not have concrete arrangement requirement, only has certain wide in range requirement to straight tube caliber and length, also lacks calculating design considerations in theory, domestic seldom have similar engineering example can for reference and use for reference.
Utility model content
Utility model object: the purpose of this utility model is for the deficiencies in the prior art, provides a kind of dissolved air water release system, can prevent and suspended substance, oils and fat that in time proportion is less than 1 in process waste water, can be used for the concentrated of mud.
Technical scheme: the utility model provides a kind of dissolved air water release system, comprise dissolved air water inlet pipe, dissolved air water hold-up vessel and dissolved air water releasing tube, in dissolved air water release, district arranges described dissolved air water hold-up vessel, dissolved air water inlet pipe described in tank skin one side joint of described dissolved air water hold-up vessel, relative opposite side is positioned at bottom air flotation pool dissolved air water release district and connects described dissolved air water releasing tube; Dissolved air water hold-up vessel can extend the dissolved air water residence time and be about 30s ~ 50s, be conducive to gas fully to contact with water, form more stable small bubbles, maintain molten gas releasing tube certain pressure simultaneously, thus ensure that molten gas releasing tube head end and end evenly can discharge dissolved air water, by regulating hold-up vessel vent valve, satiety can be got rid of and close air, guaranteeing dissolved air water effect simultaneously.
Preferably, the volume of described dissolved air water hold-up vessel is 0.3 ~ 0.5m
3, be conducive to gas and fully contact with water, form more stable small bubbles, maintain molten gas releasing tube certain pressure simultaneously.
Further, dissolved air water releasing tube described in a group is evenly distributed on tank skin along the radial direction of described dissolved air water hold-up vessel, is spaced apart 80 ~ 120cm between adjacent two dissolved air water releasing tubes, ensures the homogeneous release of release district's dissolved air water, avoids producing dead band or short stream.
Further, described in every root, dissolved air water release pipe range is 3.0 ~ 5.0m, ensures dissolved air water release evenly.
Further, on described dissolved air water releasing tube, radially tiltedly lower 45 ° of positions, every 5 ~ 10cm perforate, are avoided aperture clogs and are ensured dissolved air water release evenly.
Further, the aperture in the hole on described dissolved air water releasing tube is 2.0 ~ 4.0mm; Neither destroy small bubbles in dissolved air water on the one hand, air pocket can be cut into small bubbles again, improve air flotation effect, avoid tiny foreign material frequent jams aperture in dissolved air water on the other hand.
Further, co-apertured 50 ~ 80 of dissolved air water releasing tube described in every root, ensures that dissolved air water can discharge evenly, makes enough dissolved air waters and the abundant comprehensive engagement of mud.
Beneficial effect: by installing the air flotation pool of this kind of dissolved air water release system, mud solid content after process is increased to 4.5% from 2.2%, produce mud volume and be about reduced to original 1/2nd, more be conducive to follow-up centrifugal dehydration treatment, the backwater of air supporting simultaneously COD is reduced to 350mg/L from 900mg/L, and can ensure stable continuous service effect, the technique adjustment frequency and working strength decline to a great extent, reach floatation thickening optimum regime completely and mud solid carbon dioxide is clear.

Embodiment
Below technical solutions of the utility model are described in detail, but protection domain of the present utility model is not limited to described embodiment.
embodiment:a kind of dissolved air water release system, as shown in Figure 1, 2, comprises dissolved air water inlet pipe 1, dissolved air water hold-up vessel 2 and dissolved air water releasing tube 3, and in dissolved air water release, district 4 arranges dissolved air water hold-up vessel 2, and the volume of dissolved air water hold-up vessel 2 is 0.4m
3, and on hold-up vessel 2, vapor pipe 5 and vent valve are installed.The tank skin one side joint dissolved air water inlet pipe 1 of dissolved air water hold-up vessel 2, relative opposite side is positioned at the bottom in air flotation pool dissolved air water release district, radial direction along dissolved air water hold-up vessel 2 is evenly distributed with four dissolved air water releasing tubes 3 on tank skin, 100cm is spaced apart between dissolved air water releasing tube 3, every root dissolved air water releasing tube 3 is long is 4.0m, on dissolved air water releasing tube 3, radially tiltedly lower 45 ° of positions are every 7cm perforate, and aperture is 3.0mm, co-apertured 50 of every root dissolved air water releasing tube 3.
In the present embodiment, dissolved air water and the mud in dissolved air water release district 4 control at 30 ~ 45 minutes duration of contact, are conducive to raising air flotation effect.
As mentioned above, although represented with reference to specific preferred embodiment and described the utility model, it shall not be construed as the restriction to the utility model self.Under the spirit and scope prerequisite of the present utility model not departing from claims definition, various change can be made in the form and details to it.
