Generally contain the ammonia nitrogen of different concns in the waste water that ammonolysis product uses and enterprise such as ammonia production discharges, three kinds of physics, chemical method and biological treatments are arranged usually and remove the alternative treatment process of ammonia in the waste water.The physics method has reverse osmosis, distillation (being that steam gas is carried), ammonia stripping, soil irrigation; Chemical method has ion exchange method, break point chlorination, contains ammonia co-production, burning, catalytic pyrolysis, electrodialysis, electrochemical treatment; Biological process has algal culture, biological nitration etc.Though many methods can both be removed ammonia nitrogen effectively, have only several method can really be used for wastewater treatment.For the ammonia nitrogen waste water of a certain specific concentrations, the selection of treatment technology depends primarily on the character of waste water, treatment effect and economy.According to domestic and international related data and case history, the practical approach of handling ammonia nitrogen waste water at present mainly contains ammonia vaporizing extract process, ammonia blow-off method, break point chlorination method, ion exchange method and biological treatment.
The ammonia blow-off method is a kind of method of processing ammonia nitrogen waste water commonly used.In the existing ammonia blow-off method technology, Chinese patent ZL200420079296.2 " Ammonia blowing-out tower " and 01274455.7 " percolate Ammonia blowing-out tower " is arranged, its inside all is provided with filler unit, can make Ammonia blowing-out tower easily by the clogged with material of being filled out like this, and cleaning is got up very difficult.
The utility model content
In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of no filler efficient Ammonia blowing-out tower, and it need not filler, has avoided the filler obstruction, has increased the work-ing life of stripping tower.
In order to address the above problem, the utility model is by the following technical solutions: the efficient Ammonia blowing-out tower of no filler, comprise tower body, inlet pipe, gas recovery pipe, water inlet pipe and water outlet, it is characterized in that: described tower body is provided with gas recovery pipe from top to bottom successively, the water smoke trap, the atomisation unit assembly and the precipitation awl end, described gas recovery pipe is positioned at the tower body top, water inlet pipe links to each other with the atomisation unit assembly, the water smoke trap is between gas recovery pipe and atomisation unit assembly, inlet pipe is bored at atomisation unit assembly and precipitation at the end, and the water outlet that is positioned at the tower body bottom is positioned at the top of slag-drip opening.
As further technical scheme of the present utility model: described Ammonia blowing-out tower is a thin-high shape steel design drum.
As further technical scheme of the present utility model: described water smoke trap is made up of several layers of woven wire.
As further technical scheme of the present utility model: described atomisation unit assembly is made up of several metal shower nozzles.
As further technical scheme of the present utility model: described Ammonia blowing-out tower inwall and assembly are all done rotproofing or are used stainless steel.
As further technical scheme of the present utility model: the inner of inlet pipe is inclined upwardly.
The utility model does not have the principle of work of the efficient Ammonia blowing-out tower of filler: enter the high-pressure atomization device assembly by water inlet pipe after waste water pumps up, moment puts to press and discharges, make current become the minimum vaporific globule, greatly enlarged the surface-area of liquid, air side inlet pipe at the bottom of tower is blown into, with the spray water xi counter current contact, both sides are with good mass transfer conditions contact from bottom to top, and wind is with NH
3Blow to cat head and water sepn, remaining Mercury is caught through water smoke trap net, and ammonia enters recovery system through gas recovery pipe; Clarify after water outlet is discharged through precipitation at the bottom of tower behind the waste water deamination, sediment regularly effluxes from awl end slag-drip opening.
The beneficial effects of the utility model are: this equipment removes ammonia efficient height, one-level stripping NH
3-N clearance reaches 70%, requires to establish second-stage treatment according to water outlet, and the water outlet ammonia nitrogen can reach country's " one-level " emission standard (15mg/L or lower).Running cost is low, and under the same case, cost has only 1/3 of traditional blow-off method, 1/20 of vaporizing extract process.Operational stability is strong, does not have technical barriers such as stifled tower.The malleation air feed can be regulated inlet temperature, can effectively guarantee the technology operating temperature.
Description of drawings
Below in conjunction with accompanying drawing and example the utility model is further specified.
Fig. 1 is a structural representation of the present utility model,
Among the figure: 1 tower body, 2 inlet pipe, 3 gas recovery pipes, 4 water inlet pipes, 5 water outlets, 6 water smoke traps, 7 atomisation unit assemblies, 8 slag-drip openings, the 9 precipitation awl ends.
Embodiment
