Description
Technical field
The utility model relates to flue gas desulfurization field, specifically relates to a kind of low particle diameter flue gas swirling flow atomizing deep desulfuration device.
Background technology
Since 2013, the average haze number of days of China is maximum over 52 years, and it is maximum for the same period that Hebei etc. 13 provinces and cities haze number of days is history.Haze weather phenomenon can cause urban atmosphere acid rain, photochemical fog phenomenon, causes atmospheric visibility, hinders aerial, the water surface and road traffic, affects human immunity structure etc.
The particulates such as sulfuric acid are the main components of gray haze, and the major reason cause air pollution aggravation, haze weather increases, worsening has: the Economic Development Mode that the industries such as highly energy-consuming thermoelectricity, cement, iron and steel are extensive; The use of colm; Motor vehicle exhaust emission; Crop straw burning privately; Heating etc.
The 18 large rear Xi Jinping General Secretarys preside over Standing Committee and arrange environmental improvement, using the vital task that environmental improvement is held power as Xin Jie collective leadership.June 14, Li Keqiang held State Council's special meeting, proposed prevention and control of air pollution ten measures." suggestion about accelerating development energy-conserving and environment-protective industry " (No. (2013) 30, promulgated by the State Council) and " prevention and control of air pollution action plan " (No. (2013) 37, promulgated by the State Council) in State Council puts into effect in succession.Various places Chinese Ministry of Environmental Protection has put into effect simultaneously and has implemented prevention and control of air pollution action plan detailed rules for the implementation, has put into effect environmental protection policy the severeest and measure.The appearance of new policy requires that enterprise carries out deep desulfuration.At present, 95% thermal power plant adopts wet process of FGD, and conventional wet desulfurization investment is high, energy consumption is high, raw material consumption is high, denitration efficiency is low, cannot meet new standard requirement.
Application number be 200520051313.6 Chinese patent literature describe a kind of thermal power plant waste gas ultrasonic atomization desulfurizer, the program by arranging atomising device on the supporting plate, base arranges supersonic generator, obtains certain desulfurized effect.But be 12-15m/s because flue gas enters flow velocity before absorption tower, in absorption tower, flue gas flow rate is about 3.5m/s, and therefore high flue gas flow rate produces hole after easily making flue gas enter absorption tower, causes skewness in rising flue gas tower, makes desulfurized effect not be very desirable.
Therefore, how transforming existing desulfurizing tower, make it have good desulfurized effect, is that those skilled in the art need solution badly.
Utility model content
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provides a kind of low particle diameter flue gas swirling flow atomizing deep desulfuration device.
The utility model adopts following technical proposals:
A kind of low particle diameter flue gas swirling flow atomizing deep desulfuration device, comprise desulfurizing tower, the air inlet of desulfurizing tower exports with boiler induced-draft fan and is connected, the gas outlet of desulfurizing tower is connected with blowdown stack, demist floor, mechanical spraying floor and mechanical agitation district is disposed with from top to bottom in desulfurizing tower, also be provided with in desulfurizing tower and rotate desulfurization layer, this rotating spraying floor is between mechanical spraying floor and mechanical agitation district, and this rotating spraying layer comprises several is installed on ultrasonic nozzle on desulfurizing tower inwall, the angle of any one ultrasonic nozzle and vertical plane is 30 °-70 °.
Preferably, described ultrasonic nozzle is connected with circulating pump by pipeline.
The beneficial effects of the utility model are:
(1) flue gas entered in absorption tower can effectively be stirred evenly.
(2) the thump droplet effect produced due to ultrasonic nozzle can make flue gas be uniformly dispersed further, and steam atomization effect increases the contact area of absorbent and flue gas.These two aspects effect effectively raises the clearance of sulfur dioxide in absorption tower.
Accompanying drawing illustrates:
Fig. 1 is cut-away view of the present utility model;
Wherein: 1, air-introduced machine outlet, 2, blowdown stack, 3, demist layer, 4, mechanical spraying layer, 5, rotating spraying layer, 6, desulfurizing tower, 7, mechanical agitation district, 8, ultrasonic nozzle, 9, circulating pump.
Detailed description of the invention:
Embodiment 1: a kind of low particle diameter flue gas swirling flow atomizing deep desulfuration device, its structure is as shown in Figure 1: comprise desulfurizing tower 6, air inlet and the boiler induced-draft fan of desulfurizing tower 6 export 1 and are connected, the gas outlet of desulfurizing tower 6 is connected with blowdown stack 2, demist layer 3 is disposed with from top to bottom in desulfurizing tower 6, mechanical spraying floor 4 and mechanical agitation district 7, rotating spraying layer 5 is also provided with in described desulfurizing tower 6, this rotating spraying floor 5 is between mechanical spraying floor and mechanical agitation district, and this rotation desulfurization layer comprises several is installed on ultrasonic nozzle 8 on desulfurizing tower 6 inwall, any one ultrasonic nozzle 8 is 30 °-70 ° with the angle of vertical plane, and ultrasonic nozzle 8 is connected with circulating pump 9 by pipeline.
Principle of the present utility model is: ultrasonic nozzle 8 is 30 °-70 ° with the angle of vertical plane, by flue gas cyclonic action, stirs evenly absorption tower import flue gas.Because of flue gas enter desulfurizing tower 6 before flow velocity be 12-15m/s, in desulfurizing tower 6, flue gas flow rate is about 3.5m/s, therefore high flue gas flow rate produces hole after easily making flue gas enter desulfurizing tower 6, cause rising flue gas skewness in tower, and ultrasonic nozzle 8 can effectively stir evenly the flue gas entered in absorption tower.The particle diameter of desulfurizing agent is dropped to 50-80 μm by 1500-3000 μm by ultrasonic nozzle, desulfurizing agent is distributed in desulfurizing tower more uniformly, mixes more fully with flue gas, the desulfurized effect significantly improved.
Meanwhile, the thump droplet effect produced due to ultrasonic nozzle 8 can make flue gas be uniformly dispersed further, and atomizing increases the contact area of absorbent and flue gas.These two aspects effect effectively raises the clearance of sulfur dioxide in desulfurizing tower 6.
By reference to the accompanying drawings detailed description of the invention of the present utility model is described although above-mentioned; but the restriction not to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection domain of the present utility model.
