Abstract
The utility model relates to an ammonia blowing-out tower processing the sewerage cotaining the high concentration ammonia nitrogen, comprising a tower body, a water inlet, a water outlet, an air inlet, an air outlet, filling, etc. A draught fan, a liquid header, a liquid distributor, the filling and a water pan are ordinally arranged from top to bottom in the tower; the water inlet is connected with the liquid distributor; the tower body is directly reformed into the inlet port; the draught fan is positioned on the upper part of the water inlet. The tower increases greatly the air-water ratio under keepping the same service power; with the result that the removal ratio of the ammonia nitrogen is increased; the utility model can used for continuous process of the multitudinous industrializing ammonia nitrogen sewerage and the sewerage with the low boiling point contaminant.
Description
Technical field
The utility model relates to sewage disposal device, refers in particular to the Ammonia blowing-out tower that a kind of processing contains high concentration ammonia nitrogen sewage.
Background technology
Remove at present that the ammonia-state nitrogen technology mainly contains in the sewage: several different methods such as blow-off method (containing stripping), break point chlorination, ion exchange method, biological nitration denitrogenation, soil facture.High concentration ammonia nitrogen sewage directly adopts chemical process to handle, and working cost is too high; Directly adopt biochemical method to handle, treatment effect is subjected to wherein that ammonia nitrogen influences, and often handles not up to standard.Therefore after high concentration ammonia nitrogen sewage should be disposed a part of ammonia nitrogen with physical method earlier, handle with chemical process or biochemical method again.The ammonia blow-off method receives much concern because of its processing costs is low, effective.
In the prior art, Chinese patent 01274455 " percolate Ammonia blowing-out tower " is arranged, it takes the secondary liquid distributor, two sections filling batch, the same blower fan that uses with most of Ammonia blowing-out towers is gone into a large amount of air from the tower pucking, discharges from cat head, therefore forms malleation in tower, under the prerequisite that guarantees identical gas-water ratio, the power of required blower fan is bigger.As be used for same diameter and be 3000mm, highly be the stripping tower of 13m, guaranteeing that gas-water ratio is that the power required from the bottom inflow motor is 15kw, is 11kw and at the top blower fan power demand is set under 4500 the prerequisite.The required blower fan of stripping tower places on the ground simultaneously, because power demand is bigger, so noise is big, floor space is big.
Summary of the invention
Big at above-mentioned stripping system noise, energy consumption is high, floor space reaches the low defective of ammonia nitrogen removal frank greatly, the purpose of this utility model provides a kind of novel Ammonia blowing-out tower, can reduce the energy consumption of blower fan, improves ammonia nitrogen removal frank.
For achieving the above object, Ammonia blowing-out tower of the present utility model comprises tower body, water-in, water outlet, inlet mouth, air outlet and filler etc., be furnished with blower fan, liquid header, liquid distributor, filler and support, drip pan in the tower body from top to bottom successively, water-in links to each other with liquid distributor, inlet mouth is directly formed by the tower body transformation, and blower fan is positioned at the top of water-in.
Described tower body diameter can be according to the size decision of the water yield of disposing of sewage, and material can be carbon steel, stainless steel, glass reinforced plastic or clad steel plate.
Described blower fan is determined according to the concentration of desiring the stripping material in the water yield of disposing of sewage, the sewage.Tower body has certain height.Blower fan is placed the air-breathing little negative pressure of the intravital generation of tower that makes in top of stripping tower.Make full use of at the bottom of the tower and the barometric point of cat head poor, like this under same air quantity, save energy consumption with respect to blower fan from tower pucking wind.Above result can account formula according to the mobile mechanical energy of real fluid and verify.
Liquid distributor can be a kind of in spray-type sparger, orifice flow groove type distributor, orifice flow disc type sparger, the overflow groove type distributor according to different technology, and material can be carbon steel, stainless steel or carbon steel line with rubber.
Described liquid header is the ramp type liquid header, and material can be carbon steel, stainless steel or carbon steel line with rubber.
Described filler adopts structured packing, can be a kind of in screen waviness packings, Mellapak packing, the PVC inclined tube-type filler.
The support of filler is generally the grating support or is the gas injection cribbing, should adopt the rack beams structure for large diameter tower, and the support position thereon.
Described inlet mouth adopts the import of venetian blind type gas phase, can effectively stop airborne dust to enter in the tower, improves gas purity, avoid long-time running after, spray apertures and filler are blocked.The import of circulating type venetian blind type gas phase guarantees gas being evenly distributed in tower, does not need to increase extra gas distributor.
Principle of work of the present utility model is:
According to the ammonia stripping is the mass transfer process of liquid phase to gas phase, utilizes in the waste water phase equilibrium relationship of ammonia concentration in the ammonia concentration and gas phase, and the difference of ammonia concentration is a power in vapor phase ammonia concentration and the actual gas phase when balancing each other.Stripping surface fast updating and from liquid phase removal of ammonia and nitrogen, therefore, require waste water in the filling surface biofilm, gas-liquid conversed flowing, gas contacts with liquid and also dynamically updates fast, and the ammonia nitrogen in the waste water constantly is discharged in the air.
During work, waste water enters in the tower from water-in, distributes through liquid distributor, falls into filling batch.The liquid foam major part of being taken out of by gas is stopped distribution again by liquid header, and the liquid of taking out of is on a small quantity collected the back by liquid header and distributed, and falls into filling batch.The venetian blind type inlet mouth of air at the bottom of the tower enters in the tower, enters filling batch, discharges tower body by the air outlet from cat head by blower fan at last.In said process, waste water forms liquid film at filling surface and flows downward, and air is by the countercurrent flow of filler space, and air fully contacts at filling surface with waste water, and the ammonia in the waste water constantly is discharged in the air, reaches the purpose of ammonia stripping.
Advantage of the present utility model is: this tower places cat head with blower fan, thereby has reduced the sound pollution of blower fan to surrounding environment, and saves floor occupying area.Under the prerequisite that keeps same use power, improve gas-water ratio greatly, thereby improve ammonia nitrogen removal frank, the continuous processing of competent large-batch industrial ammonia-nitrogen sewage, lower boiling pollutent sewage.
