Abstract

The utility model provides a high scattering spray ammonia elimination tower without filler and column tray, which comprises a blast blower or an induced drafting fan, a feed water pump, a column of ammonia elimination and an inlet air distributor. The utility model has the advantages of inner high distributing parts inside of ammonia elimination tower, which is positioned at the top of inlet air distributor. The high distributing part comprises an atomizer and a distributing water pipe; the atomizer is arranged upper or lower, connected with feed water pump through distributing water pipe and inlet water pipe. The high distributing parts can treat the nitrogenous effluent highly efficiently due to increasing liquid surface scale; the escape speed of free ammonia from solution is highly increased, so that the utility model can operate reliably with high efficiency of removal of free ammonia and nitrogen from solution and lower power consumption.

Description

The high dispersive spraying removes the ammonia tower
Technical field
The utility model relates to the separating device that a kind of dispersion method is removed ammonia nitrogen in the solution.The utility model can be widely used in the processing of the ammonia nitrogen waste water of industries such as petrochemical complex, chemical fertilizer, weaving, agricultural chemicals, biological products as a kind of separating unit of economical and efficient, also can be used for the treating processes of municipal wastewater and percolate.
Background technology
Traditional ammonia nitrogen sewage treatment equipment normally selects air or water vapor to recommend matter as gas, adopts packing tower or tray column that the gas-to-liquid contact interface is provided, to reach the purpose that ammonia is removed from solution.
Adopt the packing tower separating device of air stripping method (being that air gas is carried), though can reach the requirement of part removal of ammonia and nitrogen, it is low to remove efficient, and need the waste water temperature raising winter, otherwise efficient is lower; Because blow-off method operation gas/water is than big (being generally 3000~4000), the ammonia-containing exhaust amount that causes the stripping cat head to be got rid of is big, is unfavorable for the absorption of ammonia, usually directly to airborne release, causes secondary pollution in addition; Blast height (500~800mm H2O) causes the energy consumption height, one ton of waste water power consumption of average treatment, 6~9kW; And because the restriction of vapor liquid equilibrium, blow-off method can only arrive ammonia nitrogen removal~500mg/l, does not reach emission request.
Adopt the packing tower or the tray column separating device of steam gas formulation (promptly adding thermal distillation), (usually>10000mg/l), ammonia nitrogen waste water that flow is little is handled, but is needed to consume steam and water coolant to be suitable for the ammonia-nitrogen content height.Under 0.3MPa pressure, adopt steam gas to carry the ammonia nitrogen waste water of 30000mg/l, make~10% ammoniacal liquor, one ton of waste water consumption of every processing steam 390kg, water coolant 20t, if 80 yuan/ton of steam prices, 0.10 yuan of/ton calculating of water coolant price, then priming cost is 33.2 yuan/ton; As making liquefied ammonia, one ton of waste water of every processing also need consume steam 490kg and water coolant 25t again, only makes liquefied ammonia 28kg, obviously makes liquefied ammonia and does not more calculate.
Summary of the invention
The purpose of this utility model provides a kind of high dispersive spraying of not only not had filler but also not had a tower tray and removes the ammonia tower, this tower adopts the high dispersive element that ammonia nitrogen waste water is carried out high dispersing and handles, increase considerably the flowing fluid ratio surface-area, greatly improved and be dissolved in the speed that the free ammonia in the water is escaped from liquid phase, with reach ammonia nitrogen removal frank height in the solution, energy consumption is low, the purpose that equipment is reliable.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of high dispersive spraying removes the ammonia tower, comprise gas blower or induced draft fan, service pump, remove ammonia Tata body and air intake sparger, it is characterized in that the high dispersive arrangements of elements is in removing ammonia Tata body, be positioned at the top of air intake sparger, the high dispersive element is by atomizing nozzle and divide water distributor to form, atomizing nozzle is provided with up or down, communicates with service pump by minute water distributor and water inlet pipe.
Above-mentioned high dispersive spraying removes the ammonia tower, it is characterized in that removing in the ammonia Tata body mist eliminator is set, and the high dispersive element is positioned at the top of air intake sparger and the below of mist eliminator.
Above-mentioned high dispersive spraying removes the ammonia tower, it is characterized in that according to former water and clearance requirement, remove in the ammonia tower same, but high dispersive element individual layer or double-deck the layout.
Above-mentioned high dispersive spraying removes the ammonia tower, it is characterized in that the atomizing nozzle of high dispersive element links to each other with a minute water distributor by taking over, and every branch water distributor is arranged several atomizing nozzles.
Above-mentioned high dispersive spraying removes the ammonia tower, it is characterized in that adopting single-stage or multistage setting, or arranges with the subsequent disposal tower and except that ammonia Tata body superposes.Form the arrangement form of the single tower of single-stage or multistage single tower, but the multitower serial or parallel connection uses as required.
The spraying of above-mentioned high dispersive removes the ammonia tower, it is characterized in that described to remove ammonia Tata body be vertical, or adopts horizontal according to field condition; When being horizontal, the high dispersive element is positioned at the rear of air intake sparger, and the atomizing nozzle of high dispersive element is laterally placed.
The spraying of above-mentioned high dispersive removes the ammonia tower, it is characterized in that described to remove ammonia Tata body be steel construction piece, or concrete structure.
Advantage of the present utility model is that the solution that adopts the high dispersive element will contain ammonia nitrogen carries out high dispersing, make it to become small liquid particle, free ammonia shifts to gas phase in the liquid phase speed and probability have been quickened greatly, only need the air of relatively small amount just the ammonia of overflowing can be taken away, its ammonia nitrogen removal mechanism is that liquid height disperses and then generation surface chemistry effect, break blow-off method and removed the restriction that efficient is influenced by the gas-liquid dissolution equilibrium constant, the ammonia nitrogen removal frank height adopts multiple-stage treatment can reach discharging standards; Blow-off method ammonia nitrogen removal principle is based on the vapor liquid equilibrium of solution, therefore must increase gas/water ratio and promptly strengthen the stripping air capacity reduces ammonia to increase inert gas content in the gas phase equilibrium partial pressure, improves the rate of transform of free ammonia.
As add the solution that suitable interpolation auxiliary agent will help to contain ammonia nitrogen and carry out high dispersing, make it to become small liquid particle.
Another remarkable advantage of the present utility model also is its employing void tower spraying, whole tower resistance is little, thereby required air pressure is low, add that this tower operation gas/water is than low, it only is 1/3~1/2 of blow-off method, therefore handle only power consumption 2~2.5kW of one ton of waste water (qualified discharge), reduced energy consumption and processing cost.In addition, this tower has been cancelled filler owing to adopt the void tower operation, avoided because filler corrosion or aging channel and the dead band that produces, and iron rust or fragment is to the obstruction of pipeline, so does not need frequent maintenance, has the advantage of stable and reliable operation.
