Abstract
The utility model relates to a desulfurizing tower for absorbing escaped ammonia from a boiler flue by utilizing circulating water, belonging to the technical field of environmental protection. A defroster, an upper circulating water spraying layer, a desulfurizing tower interlayer, a lower circulating water spraying layer and a lower spraying layer are arranged in a tower from top to bottom. The desulfurizing interlayer is provided with a plurality of air vents, the air vents are provided with an air cap, a water tank is formed between the air vents, and the water tank is mutually communicated with the upper circulating water spraying layer and the lower circulating water spraying layer through a circulating water pump and a circulating water tube. After the flue in the desulfurizing tower is processed by a desulfurizing system, the SO2 is basically removed, the rest ammonia (NH3) and a very small amount of SO2 which are mixed in the purified flue, are dissolved in water after being cleaned by the sprayed circulating water, the circulating water flows downwards, and mixes with the circulating liquid to form desulfurizing mixed liquid, thus the recycle of ammonia can be realized, at the same time, the secondary pollution of ammonia to the environment can be eliminated, and the utility model is beneficial to the environmental protection.
Description
Technical field
The utility model relates to a kind of desulfurizing tower that utilizes recirculated water to absorb escape ammonia from boiler smoke, belongs to environmental protection technical field.
Background technology
Can accomplish not have waste residue and discharging of waste liquid to the ammonia process of desulfurization of boiler smoke, the product ammonium sulfate of generation can be utilized.But exist the phenomenon of the escaping of ammonia, cause air secondary is polluted.The escaping of ammonia mainly is because ammoniacal liquor enters desulfurizing tower and is heated suddenly later on, partial ammonia water also is not able to do in time to carry out chemical reaction with sulfur dioxide and just meets thermal decomposition, after having become ammonia and steam, ammonia wherein together enters in the atmosphere with flue gas, causes the pollution to atmosphere.
Summary of the invention
The purpose of this utility model is to propose a kind of desulfurizing tower that utilizes recirculated water to absorb escape ammonia from boiler smoke, change the structure of existing desulfurizing tower, smoke outlet at desulfurizing tower increases by a cover circulating water device, absorb the ammonia of escaping with the recycled process water, with the ammonia in the further recovery flue gas, reach the purpose of recycling, eliminate ammonia again to second environmental pollution simultaneously.
The recirculated water that utilizes that the utility model proposes absorbs the desulfurizing tower of escape ammonia from boiler smoke, in the tower body, be provided with demister, cocycle water spraying layer, desulfurizing tower interlayer, following recirculated water spraying layer and following spraying layer from top to bottom successively; Described desulfurizing tower interlayer is provided with a plurality of passages, and passage is provided with gas cap, forms tank between the passage, and tank is interconnected by water circulating pump and circulating water pipe and cocycle water spraying layer and following recirculated water spraying layer.
The recirculated water that utilizes that the utility model proposes absorbs the desulfurizing tower of escape ammonia from boiler smoke, flue gas is handled through ammonia method desulfurizing system, SO wherein
2Substantially be removed, but still some remaining ammonia (NH
3) and a spot of SO
2Be blended in and purify in the flue gas these remaining NH
3With SO
2The washing of the recirculated water of process spray is dissolved in the water, and recirculated water moves downwards, is merged into as the desulfurization mixed liquor with circulation fluid, has realized the recycling to ammonia, eliminates ammonia again to second environmental pollution simultaneously, helps environmental protection.
Description of drawings
Fig. 1 is that the recirculated water that utilizes that the utility model proposes absorbs the structural representation of the device of escape ammonia from boiler smoke.
Among Fig. 1, the 1st, cat head, the 2nd, demister, the 3rd, cocycle water spraying layer, the 4th, gas cap, the 5th, the desulfurizing tower interlayer, the 6th, passage, the 7th, water circulating pump, the 8th, circulating water pipe, the 9th, replenish water pipe, the 10th, tank, the 11st, following recirculated water spraying layer, the 12nd, following spraying layer.Arrow is the flue gas traffic direction among the figure.
The specific embodiment
The recirculated water that utilizes that the utility model proposes absorbs the desulfurizing tower of escape ammonia from boiler smoke, its structure as shown in Figure 1, in the tower body,, be provided with demister 2, cocycle water spraying layer 3, desulfurizing tower interlayer 5, following recirculated water spraying layer 11 and following spraying layer 12 from top to bottom successively from cat head 1.Desulfurizing tower interlayer 5 is provided with a plurality of passages 6, and passage 6 is provided with gas cap, forms tank 10 between the passage 6, and tank 10 is interconnected with cocycle water spraying layer 3 and following recirculated water spraying layer 11 by water circulating pump 7 and circulating water pipe 8.
Introduce the operation principle and the course of work of the desulfurizing tower that the utility model proposes in detail below in conjunction with accompanying drawing:
Inside contain remaining sulfur dioxide and not complete reaction ammonia be cleaned flue gas, enter in the tower from the desulfurizing tower bottom.Flue gas enters the recirculated water uptake zone by upwards operation of the blow vent on the desulfurizing tower interlayer 56, continues haptoreaction with ejection recirculated water in the shower nozzle of cocycle water spraying layer 3, generates ammoniacal liquor, ammonium sulfite or sulfurous acid.These products move downwards with recirculated water, enter the absorption region of being made up of following recirculated water spraying layer 11 and following spraying layer 12.In order to prevent that recirculated water from directly entering the absorption region, on passage 6, add gas cap 4, move downwards to stop recirculated water, and flue gas can upwards move.Recirculated water by circulating pump 7 pressurization, follows in the shower nozzle that ring water pipe 8 enters cocycle water spraying layer 3 and following recirculated water spraying layer 11 and sprays in running, enters circulating pump again and circulates successively.Flue gas was further purified and was reached emission standards fully this moment.The flue gas that is cleaned removes most of moisture through demister 2 after cat head 1 enters the chimney discharge.Additional water pipe 9 wherein is used for replenishing the water source to circulation.The water spray of following spraying layer 12 wherein extracts (the figure for illustrating) by circulating pump from the bottom of desulfurizing tower.
Among the embodiment of the present utility model, the used fog that removes is developed limited formula production by Beijing epoch safe section purification techniques.The product that also can use Wuhan Keep-Hope Environmental Protection Co., Ltd. to produce.
