Description

A kind of flue gas eddy flow disperser for flue gas desulphurization system

Technical field

This utility model relates to a kind of flue gas desulfurization technique field, particularly to a kind of flue gas for flue gas desulphurization system Eddy flow disperser.

Background technology

Along with the fast development of China's economy, the demand of the energy is also continuously increased, as the coal of primary energy, in phase When remaining China's main energy sources in long period.

At present.In China Power energy resource structure, coal electricity accounts for 3/4, and does not have the biggest within some time to come Change.Coal fired thermal power plant, during primary energy coal is converted to secondary energy sources electric power, can produce waste gas, waste water, ash The pollutant such as slag and noise, the SO in its waste gas₂It is one of the major pollutants of air.China city SO₂Pollute the most serious. A large amount of SO₂Discharge be China's rainfall in acid main cause, acid rain is increasingly severe to the environmental pollution of China, it has also become The country of the third-largest Acid Rain Pollution behind North America and Europe in the world.By 2005, China's acid rain depositions critical load exceedance ground District is up to 3,200,000 K, accounts for the 29% of area, SO₂The acid rain harm face caused is extremely wide, including agricultural, industry, traffic All many-sides such as transport, building, health of human body, the economic loss caused can not be estimated especially.Owing to acid rain is to mankind's ring Border causes serious harm, proposes atomosphere quality standard, SO all over the world one after another with health organization₂A large amount of discharges the tightest Heavily contaminated environment causes again the huge waste of Sulphur ressource, reduces SO₂Pollute and become the task of top priority that current atmospheric environment is administered.

Economic condition and technical conditions that China is current the most do not allow to put into substantial amounts of manpower and thing as developed country Power, and administering SO₂Aspect starting ratio is later.Along with experience and the maturation of technology, each complete equipment gradually achieves production domesticization, The most very important desulfurizing tower has realized production domesticization the most, owing to the sweetening process of flue gas is carried out, in desulfurizing tower in desulfurizing tower Gas liquid two-phase flow feature be one of key factor affecting desulfurized effect.

Utility model content

This utility model, for the deficiencies in the prior art, proposes a kind of flue gas eddy flow for flue gas desulphurization system and spreads dress Put.

The technical solution of the utility model is achieved in that

A kind of flue gas eddy flow disperser for flue gas desulphurization system, including smoke inlet pipe, guide vane, water conservancy diversion gear Plate, the tail end of described smoke inlet pipe is closed tail end, at the tube wall lateral symmetry uniform ordered series of numbers INO Intake Open of smoke inlet pipe Mouthful, in air inlet openings, arc circulation guide vane is set along smoke inlet pipe axial both sides, this arc circulation guide vane tail end Tangent line parallel, the upper and lower position of the vertical direction of described arc circulation guide vane is coated with flow apron.

Preferably, described air inlet openings is strip gab.

The beneficial effects of the utility model are:

1. make flue gas form a rotational flow field in desulfurizing tower to contact with being sufficiently mixed of desulfurizing agent to realize flue gas, prolong Long gas residence time, the desulphurization reaction process in reinforcing desulfuration tower, give full play to the useful space in desulfurizing tower, remove smoke Deflection, is completely eliminated gas-to-liquid contact blind area, improves gas-liquid mass transfer efficiency, can reach higher taking off in the case of relatively low calcium sulfur ratio Sulphur efficiency；2. simple in construction, it is simple to manufacture, it is easy to anticorrosive construction, service life is long, and desulphurization plant can be kept properly functioning；3. Internal overhaul, is greatly shortened the repair time；4. good purification, consume energy little, low cost；5. it is difficult to deposition, fouling, blocking.

Accompanying drawing explanation

In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, the accompanying drawing in describing below is only It is embodiments more of the present utility model, for those of ordinary skill in the art, in the premise not paying creative work Under, it is also possible to other accompanying drawing is obtained according to these accompanying drawings.

Fig. 1 is cross-sectional structural representation of the present utility model；

Fig. 2 is Structure of Flue Gas Desulfuration Absorbing schematic diagram in embodiment.

In figure: 1, smoke inlet pipe；2, air inlet openings；3, arc circulation guide vane；4, flow apron；5, diffuse out Mouthful；6. neat stress outlet；7. demister；8. desulfurizing agent spraying layer；9. desulfurizing tower；10. agitator；11. desulfurizing agent stock tanks.

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise The every other embodiment obtained, broadly falls into the scope of this utility model protection.

As shown in Figure 1, 2, a kind of flue gas eddy flow disperser for flue gas desulphurization system, including smoke inlet pipe 1, institute The tail end stating smoke inlet pipe 1 is closed tail end, in the tube wall lateral symmetry uniform ordered series of numbers air inlet openings 2 of smoke inlet pipe 1, Arranging arc circulation guide vane 3 in air inlet openings 2 along the axial both sides of smoke inlet pipe 1, arc circulation guide vane 3 can lure Leading flue gas orbiting motion circumferentially, air-flow can be tangentially internal around desulfurizing tower 9, forms rotating flow, not only increases gas-liquid mass transfer Efficiency and time of contact and contact area, also under the synergism of centrifugal force and gravity, by drop and solid particle from flue gas In separate, solve tradition desulfurizing tower 9 flow field shearing force less, air stream turbulence insufficient strength, flue gas connects with desulfurizing agent Touching insufficient, the problem that desulfurization degree is the highest, the tangent line of this arc circulation guide vane 3 tail end is parallel, and described arc circulation guides The upper and lower position of the vertical direction of blade 3 is coated with flow apron 4, and flow apron 4 can make air inlet openings 2 at a segment distance In the range of formed all round closure space, flue gas can only be flowed out by outlet diffusor 5, aggravation flue gas circumferential orbiting motion.

Described air inlet openings 2 is strip gab.

During use, eddy flow disperser is arranged on more than desulfurizing agent stock tank 11 liquid level, eddy flow disperser afterbody and desulfurization Certain distance is left between tower 9 inwall.Flue gas is entered desulfurizing tower 9 by the smoke inlet pipe 1 of eddy flow disperser, flue gas from lower and Upper flowing, the desulfurizing agent bottom desulfurizing tower 9 is fine drop through desulfurizing agent spraying layer 8 atomization, falls from top to bottom, forms mist Post.Drop drops back into gas-liquid two-phase contact during desulfurizing agent stock tank 11, the SO in washing flue gas₂、SO₃, HCL etc., through desulfurizing agent Neat stress after washing is flowed out by neat stress outlet 6 after removing droplet by demister 7.Desulfurizing tower 9 end, is provided with agitator 10.

These are only preferred embodiment of the present utility model, not in order to limit this utility model, all in this practicality Within novel spirit and principle, any modification, equivalent substitution and improvement etc. made, should be included in guarantor of the present utility model Within the scope of protecting.
