Description
Technical field
The utility model relates to flue-gas purification treatment device technical field, relates to more specifically a kind of boiler flue gas purification treatment system of biomass fuel.
Background technology
Biomass energy is that the photosynthesis by plant is fixed on tellurian solar energy, solid forming biomass fuel utilizes agriculture and forestry organic waste material (as straw, peanut shell, leaf, branch, wood chip, Chinese silvergrass, wood shavings etc.) as raw material exactly, through pulverizing, push, drying, makes solid forming biomass fuel.Along with the development in epoch, environmental protection standard increasingly stringent, protection of the environment, improves environment and prevents ecological disruption, creates clean adapt circumstance, and protection health is the urgent demand of people instantly.And the importance of effectively administering smoke pollution of boiler highlights further.The tail gas that in atmosphere pollution is mainly boiler emission contains certain flue dust and acidic materials, if without processing, directly outer row will pollute surrounding environment, and harm periphery resident's is healthy, produces acid rain, destroys the ecological balance.Country, for protection of the environment, improves environment and prevents ecological disruption, has put into effect the laws and regulations of serial environmental protection, and requiring boiler exhaust gas must the comprehensive regulation to reach related standards could discharge.
Biomass energy is called as " the fourth-largest energy ", contributes to significantly to reduce greenhouse gas emission, reduces carbon emission amount, reduces air pollution, is also conducive to realize energy diversification, reduces the dependence of China to traditional energies such as coal, oil, natural gases.But flying dust is large after solid forming biomass fuel combustion, flue dust is more much larger than coal-fired flue gas flue dust, and flue gas is constantly with Mars, so flue gas processing is also the problem of the solutions such as a letter after current solid forming biomass fuel combustion.
The processing method of the current biomass fuel boiler flue gas in use generally still adopts the flue gas processing method of coal-burning boiler, mainly contains: electric precipitation, venturi water film deduster, bag-type dusting, spiral board wet type (numb stone) dedusting.Desulfurization method mainly contains: desulfuration in furnace, flue gas dry-type desulfurization, fume wet type desulphurization etc.Electric precipitation: the existing electric dust collector purification efficiency eminence body scope amount of regulating the flow of vital energy is large, but equipment is huge, and floor space is large, consumption steel are many, invest greatlyr, and device structure is more complicated, the required precision of manufacturing, installing is high, and operation and maintenance expense is many, and the ratio resistance of dust be there are certain requirements.
Venturi water film deduster: venturi water film deduster is with its small investment, the advantage such as floor space is little, simple in structure, maintenance workload is few, operational management is convenient, in boiler flue gas purification field, occupy critical role always, but from the more severization of environmental protection standard, making the performance of venturi scrubber own can not meet environmental requirement will progressively be eliminated.
Spiral board wet type (numb stone) dedusting: wet method formula spiral board purifying column desulfurization and dust-removal method, soda method absorbent absorbability is large, technical maturity, simple, absorption efficiency is high, to absorbing yarn system, there is not the problems such as fouling, obstruction, but alkali consumption is large, cost is high, is not therefore suitable for the improvement of the flue gas of medium and small tolerance.
Sack cleaner: also claim filtration dust catcher, advantage has:
(1) when the synthetic fibers that adopt glass fibre and some kind are made filter bag, can stable operation at the temperature of 160～200 ℃, while having the high-performance of selection filtrate, some heatproof can reach 260 ℃;
(2), when for dry method desulfuration system, can suitably improve desulfuration efficiency.
(3) scope of processing gas flow is large, and can process the very dusty gas of high concentration, so it can be used as the deduster of various dusty gases.Its capacity can be less than to several cubic metres per minute, arrive the air-flow of hundreds thousand of cubic metres per minute greatly, when adopting highdensity synthetic fibers filter bag and pulse recoil purge mode, it can process the dusty gas that dust concentration surpasses 700000mg/m3.
But also there is following shortcoming in it:
(1) be unsuitable for operation work under the condition of high temperature, in flue gas, dust moisture content is important surpasses 25% when above, and dust is the stifled bag of sticky bag easily, causes cloth bag deashing difficulty, resistance to raise, and premature failure is damaged;
(2) compare drag losses with electric precipitation slightly large, be generally 1000～2000Pa;
(3) when burning high-sulfur cigarette or flue gas are processed without devices such as desulfurization, flue gas sulphur oxide, oxynitride concentration when very high, except FE filtrate, the damage that all can be corroded of other chemical fibre synthetic fiber filter materials, the cloth bag lost of life;
(4) can not under " dewfall " state, work.
Obviously, existing smoke pollution of boiler administration way can not meet new environmental requirement.For above-mentioned, in order to reduce construction investment and to reduce processing cost, solve the variety of issue occurring in existing biomass fuel boiler smoke gas treatment, be necessary to develop a kind of for solid forming biomass fuel boiler system for cleaning fume.
