At present, mainly contain for the high-concentration industrial ammonia-nitrogen waste water treatment process: blow-off method, vaporizing extract process, ammonia still process method, chemical precipitation method.Wherein, chemical precipitation method is higher owing to running cost, complicated operation, and not yet large-scale through engineering approaches is used; Stripping, stripping, three kinds of methods of ammonia still process are used as traditional ammonia-removal process and use comparatively extensive in wastewater treatment.Ammonia still process method deamination effect is better, and so its required equipment is had relatively high expectations, and investment running cost is larger; And blow-off method, the supporting treatment facility of vaporizing extract process requires lower, and be conventional packing tower or board-like separating device, for example Chinese patent CN201110363900.9 discloses a kind of a kind of ammonia-nitrogen desorption absorption integrated tower that discloses, it is characterized in that, top at tower body is provided with air water separator, bottom at air water separator is provided with the absorption water distributor successively, the umbrella bucker, the sewage water distributor, the first packing area, the second packing area, return line is located at a side of umbrella bucker, fan interface is located on the tower body of bottom one side of the second packing area, water outlet is located at bottom one side of tower body, it is still to adopt the purpose that the filler mode reaches mixing wastewater with air is set, waste water can not fully mix with gas when flowing through packing layer, required gas-liquid is more, and easily produces the phenomenon of ditch Lu Biliu, affects the stripping effect; And for example Chinese patent ZL200720006185.2 discloses ammonia nitrogen blowing-off device, be provided with circular cylinder body, be provided with water inlet pipe and suspension ring on circular cylinder body top, be provided with venting port at the circular cylinder body top, outlet at water inlet pipe is provided with the diffusion tube head, sieve plate, back-up block and manhole, diffusion tube head entrance taps into water pipe, be provided with blast pipe in the circular cylinder body bottom, feet and rising pipe, be provided with ceramic Pall ring and lower ceramic Pall ring at the circular cylinder body inner chamber, have the upper support beam at upper ceramic Pall ring, between upper ceramic Pall ring and supporting beam, be provided with upper face plate and back-up block.Have the lower support beam at lower ceramic Pall ring, between lower ceramic Pall ring and lower support beam, be provided with lower face plate and back-up block, by in the circular cylinder body inner chamber, being equivalent to the ceramic Pall ring of filler, thereby reach the purpose of gas-liquid mixed, required gas-liquid is still more, ditch road wall flow phenomenon seriously causes energy consumption higher, and removal effect is unstable, haves much room for improvement.
The efficient deammoniation tower of Chinese patent CN1600693A, for the characteristics of ammonia-nitrogen desorption agent, design a kind of ammonia-nitrogen stripping tower as column plate in bubble-cap, float valve, sieve plate, ligulate, the screen, although this kind equipment has reduced total vapour-liquid ratio, but channel wall flow phenomenon can occur, have much room for improvement.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of packing layer that need not to arrange is provided, the gas-liquid demand is few, the ammonia nitrogen in waste water stripping processing reaction device that energy consumption is low.
The present invention is for solving the problems of the technologies described above, provide following technical scheme: a kind of ammonia nitrogen in waste water stripping processing reaction device, comprise housing, in the housing from top to bottom successively the interval be laid with gas-water separation layer, water-distributing device, umbrella bucker, distribution device, the umbrella bucker is separated into up and down two chambers with housing, be provided with water shoot on upper chamber's bottom shell, it is characterized in that water-distributing device is comprised of water inlet pipe, inlet pipe, two-fluid spray nozzle, described water inlet pipe is communicated with inlet pipe, connectivity part is provided with direction two-fluid spray nozzle down and consists of three-port structure.
As a further improvement on the present invention, described three-port structure is a straight tube-like, and both sides are respectively water inlet pipe and inlet pipe, two-fluid spray nozzle are arranged at water inlet pipe and inlet pipe junction.
As a further improvement on the present invention, distribution device is comprised of one the gas distributor of being at least that is arranged at inlet pipe on the lower chambers housing sidewall, be connected with inlet pipe.
As a further improvement on the present invention, distribution device is by being arranged at inlet pipe on the lower chambers housing sidewall, forming over against several evenly distributed sheet spiral cylinders of inlet pipe setting.By this kind setting, make the air that enters from inlet pipe by the spiral stream guidance characteristic of borded pile, gas and changing is flowed to directly produce upstream, and greatly enlarged the cloth headroom, make whole lower chambers be full of air, raising gas distribution efficient.
As present invention further optimization, sheet spiral cylinder quantity is 24-32/m
2Preferred by this kind, arrange sheet borded pile body according to minimum vapour lock and the even cloth effect of maximum gas, greatly improved gas distribution efficient.
As a further improvement on the present invention, water inlet pipe connects intake pump, and inlet pipe connects air compressor.
As a further improvement on the present invention, the water inlet pipe intake pressure is 0.1-0.5MPa, and the inlet pipe intake pressure is 0.1-0.5MPa, by this kind setting, waste water is fully mixed with air, and the spraying pressure of two-fluid spray nozzle is provided.
As present invention further optimization, the water inlet pipe intake pressure is 0.3MPa, and the inlet pipe intake pressure is 0.3MPa.
As a further improvement on the present invention, gas distributor is a hollow chamber, and chamber one surface offers several equally distributed qi-emitting holes.By this kind setting, effectively to gas cut apart, water conservancy diversion, uniform.
