Description

A kind of compound lector desulphurization plant
Technical field
The utility model relates to a kind of compound lector desulphurization plant, belongs to dust, fume purification techniques field.
Background technology
China's State of Air pollution is on the rise, and be with in Jing-jin-ji region, the Yangtze River Delta, Pearl River Delta one especially, haze pollution problem is especially outstanding, and atmosphere polluting problem has become the key factor of restriction socio-economic development.SO 2, NO x, VOCs, NH 3, fine particle etc. is the priority pollutant causing haze to pollute, and SO 2it is the Main Factors causing Acid Rain Pollution phenomenon.The industries such as metallurgy, oil, chemical industry, iron and steel, building materials, electric power are the important sources of dust, flue dust and smoke pollution, research and develop novel dust removing desulphurization plant, contribute to from Sources controlling atmosphere pollution, reduce the discharge capacity of industrial pollutants.
Flue gas desulfurization technique has wet method, dry method, half wet process three kinds, and wet desulphurization makes flue gas and chemical liquid react or utilizes physical support to absorb flue gas, reaches reduce SO with this 2object.Wet desulphurization equipment develops into the various new equipment such as packed tower, spray Sieve plates, spray high speed tower, liquid column tower, bubble tower from initial spray column.Ammonia type flue gas desulfurizing technology is the flue gas desulfurization technique of comparative maturity, and lime stone-gypsum sulfur removal technology is Application comparison technique early in desulfur technology.Wet desulphurization reaction speed is fast, absorption efficiency is high, therefore becomes the sulfur removal technology be most widely used.
Dedusting technology comprises mechanical type dedusting, inertial dust collection, electric precipitation, wet dust removal, filtering type dedusting etc.Sack cleaner is subject to the impact of flue-gas temperature, humidity etc., needs to regularly replace cloth bag, adds cost.Once have a cloth bag to damage will shut down replacing in hundreds and thousands of cloth bags, and the cloth bag will finding out damage in numerous cloth bags neither an easy thing.In addition, due to the difference of the situation such as temperature, water content of flue gas, higher requirement is proposed to the material of filter cloth.Although there is the filter cloth of some New Type Material, filtrate in recent years, bring no small financial burden because operating cost is high to enterprise.The dry dedusting technology such as bag-type dust, electric precipitation can not solve the desulphurization problem of flue gas, also must install wet type desulfurizing equipment in rear end.
Current dedusting technology is just towards following future development: (1) is studied more adding system to traditional dedusting technology and goed deep into; (2) high efficiency of dedusting technology, global function, low cost and stable operation is required; (3) focus on the coupling of various dedusting technology, make dedusting and desulphurization integrated.Day by day tightening up of discharge standard requires that the development of dedusting technology is more strict to equipment, researches and develops novel integration dust-removing desulphurization plant for raising efficiency of dust collection, reduces discharging SO 2be even more important.
Chinese patent CN2796810Y discloses a kind of wet dust desulfurization equipment, this equipment has spray column and catches a tower formation, by boiling-house, two towers are connected, the techniques such as spray, impact, flue gas even distribution, bubble absorption are completely newly combined, reaches the object of dust-removal and desulfurizing.
China CN201543367U discloses a kind of Wet smoke dust-removing desulfurating apparatus, this device integrates eddy flow water film dedusting, impacts dedusting, foam absorbing, hollow-spraying-tower technology, be combined the technical scheme forming complex control system by absorption tower with outer cylinder body, reach good dust-removal and desulfurizing effect equally.
China CN201719948U discloses a kind of smoke dust-removing equipment, this equipment is made up of the smoke-intake pipe connected in turn, numb stone cylindrical shell and smoke exhaust pipe, spray equipment is provided with at the air inlet of smoke-intake pipe, this device effectively can reduce particle in boiler emission flue gas and content of sulfur dioxide, makes fume emission up to standard.
More than the equipment described in invention all can effectively to clarifying smoke, but complex structure, the improvement in the textural shortage details of equipment, the complementary energy of the impact process related to is not fully used, and causes the loss of energy.This external equipment runs, the cost of management process lacks estimation, has no utilization example.
