Description
Affiliated technical field
The present invention relates to a kind of desulphurization plant, particularly a kind of wet desulphurization equipment.
Background technology
China is coal-fired big country, and during primary energy forms, fire coal accounts for 75%, and SO2 emissions 90% come from burning of coal.How realizing that the energy effectively utilizes, reduce the pollution to ecological environment when fast economic growth, is the key issue that China's economic and social harmonious development need to solve.Will prevent and treat sulfur dioxide pollution in China, the discharge of controlling the three opium sources of the gas such as thermal power plant, Industrial Boiler and stove is crucial, and flue gas desulfurization technique (FGD) is the main path that solves smoke emissioning pollution.
The flue gas desulfurization technique of countries in the world research and development and business application is over 200 kinds.Whether by desulfurization product, reclaim, flue gas desulfurization, the former directly discharges by the desulfurization mixture if can be divided into the method for abandoning and regeneration absorption method, the latter reclaims desulfurizing byproduct with forms such as sulfuric acid or sulphur.Press the dry wet form of desulfurization product, flue gas desulfurization can be divided into wet method, semidry method and dry process again.
Most alkaline slurry or the solution of adopting of wet fuel gas desulfurizing technology is made absorbent, and the forced oxidation wet type desulfurizing mode that wherein lime stone or lime are absorbent is current most popular desulfur technology.Lime stone or lime washing agent react with the SO2 in flue gas, and product calcium sulfate precipitates in cleaning solution, after separating, both can abandon, and also can gypsum form reclaim.Current technology great majority have adopted the high throughput scrubbing tower, and the 300MW unit can be with an absorption tower, thereby has saved investment and operating cost.The operational reliability of system has reached more than 99%, by adding organic acid, can make desulfuration efficiency bring up to more than 95%.
Other wet type desulfurizing technique comprises with sodium base, magnesium base, seawater and ammonia makes absorbent, is generally used for small power plant and Industrial Boiler.That the technique that the seawater of take is absorbent has is simple in structure, need not add chemicals, invest the characteristics such as little and operating cost is low.The desulfuration efficiency that ammonia stripping Fa Keda is very high, accessory substance ammonium sulfate and ammonium nitrate are salable chemical fertilizer.
The Chinese utility model patent that application number is 200820112148.4 discloses a kind of double cyclones serial connection Pneumatic emulsifying desulfurizing tower, by equal air chamber, air inlet pipe, discharging tube, the double cyclones filter chamber, the feed pipe assembly, dehydrating demisting is bored under chamber, the dehydrating demisting chamber, dehydrating demisting chamber epicone, escape pipe forms, its core component is two cyclones that the serial connection in the Pneumatic emulsifying filter chamber is installed, be imported into cyclone under the effect of flue gas air-introduced machine outside tower, the circulation fluid chopping that flue gas carrys out feeding pipe assembly, and cut more and more carefullyyer, form the Pneumatic emulsifying liquid layer of a continuous operation, flue gas is in the process of chopping circulation fluid, gas, liquid, the solid three-phase carries out strong mass transfer in the emulsification liquid layer, SO in flue gas
2be removed Deng nuisance, use the cyclone of two serial connections, will produce two Pneumatic emulsifying liquid layers, greatly improved desulfurization degree, liquid-gas ratio significantly reduces.Suitably improved, this scheme can also further improve the efficiency of desulfurization.
Summary of the invention
The present invention's technical scheme adopted that achieves the above object is, eddy current energy collecting desulfurizing tower comprises that air inlet pipe, energy collecting chamber, discharging tube, filter chamber, feed pipe assembly, dehydrating demisting chamber, escape pipe form, the feed pipe assembly is comprised of water main 9, one-level feed pipe 8, secondary feed pipe 7 and three grades of feed pipes 6, described one-level feed pipe 8, secondary feed pipe 7 and three grades of feed pipes 6 are positioned at filter chamber, and be provided with sprayer, between described secondary feed pipe 7 and described three grades of feed pipes 6, be provided with vortex generator.Vortex generator is double cyclones.
Eddy current energy collecting Structure of Flue Gas Desulfuration Absorbing of the present invention is simple, long service life, operating cost is low, can be with the sulfur dioxide flue gas that is used in more variable concentrations, and adapt to the desulfurizing agent of various alkalescence and industrial wastes aspect desulfurizing agent, owing to having adopted rotational flow generator and multi-stage spray, thereby desulfuration efficiency is high, to various sulfur-containing smoke gas, desulfurization degree reaches 95% ~ 99%.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
As follows to the detailed description of the invention by reference to the accompanying drawings.
As shown in Figure 1, under the effect of blower fan, pending flue gas enters the bottom of desulfurizing tower from the air inlet pipe 1 of desulfurizing tower 20 belows, and the energy collecting chamber, gather wind energy the cooling of flue gas.
Behind the energy collecting chamber, the mist layer of the absorption liquid that the sprayer that flue gas is subject to arranging on one-level feed pipe 8 sprays, part SO2 is absorbed.Flue gas continues to rise, core component-vortex generator 2 with certain speed by desulfurizing tower, this vortex generator is double cyclones, its efficiency is high, absorption liquid under the sprayer spray arranged on flue gas and secondary feed pipe 7 collides mutually, forms an eddy current gas-liquid layer 3.In eddy current gas-liquid layer, gas-liquid continues collision, and absorption liquid is ground into trickle one by one drop, gas-liquid layer progressive additive, and old gas-liquid layer is replaced by new gas-liquid layer, at the bottom of flowing to tower with the SO2 that is captured.As long as air-introduced machine work, new and old eddy current gas-liquid layer will alternately form.So far, the most of SO2 in flue gas is absorbed, but still it is residual to have a small amount of SO2.When flue gas continues to rise, the injection of the absorption liquid under the sprayer spray that also will be subject to arranging on three grades of feed pipes 6, SO2 residual in flue gas will further be absorbed.
Flue gas after desulfurization contains large quantity of moisture, continues to rise through removing fog chamber 5.Remove the mechanical water in flue gas except fog chamber adopts coalescence and principle of inertia, have the partial desulfurization function concurrently.Discharge outside desulfurizing tower and enter atmosphere through escape pipe 4 finally by the flue gas purified.Absorption liquid falls the desulfurizing tower bottom after absorbing SO2, enters the absorption liquid container by discharging tube 10 and recycles.
The absorption liquid of water main 9 liquid containers of self-absorption in the future is delivered to one-level feed pipe 8, secondary feed pipe 7 and three grades of feed pipes 6.
