Description
Technical field
The present invention relates to the technology of dioxin emission control in the burning method disposal of solid discarded object process, particularly relate to a kind of method and system that recycle dioxin discharging in the sulphur-containing inhibitor control flue gas.
Background technology
Along with China's economy development and quickening of urbanization process at a high speed, the generation of domestic waste and trade waste increases rapidly.Burning method is processed solid waste because treating capacity is big, and it is good to subtract capacitive, and is innoxious thorough, and can reclaim heat, therefore at home and abroad obtains using more and more widely.China's recent years successively builds up the bulky refuse incineration plant in most of city.Yet can produce the noxious materials such as dioxin in the Refuse Incineration Process.Dioxin toxicity is very big, and is difficult to obtain degraded at nature, such as strictly control, will bring serious harm to natural environment and people healthy.Therefore, generation and discharging how to control dioxin have become extremely urgent, anxious to be resolved problem.
To the control of the dioxin in domestic waste and the danger wastes burning process, method commonly used has both at home and abroad: sack cleaner contains ammonia inhibitor etc. in conjunction with charcoal absorption, interpolation sulfur-bearing.Sack cleaner in conjunction with charcoal absorption be at present domestic and international many incinerators generally adopt the dioxin control method.This method is by pulverous active carbon being spurted into the dioxin that adsorbs in the flue in the gas phase, filter lower flying dust and active carbon with deduster then, thereby minimizing being by the dioxin amount of smoke stack emission.But there are two main defectives in this method: the one, and itself can not reduce the total amount of dioxin this method, just the dioxin in the gas phase is collected in solid phase then by the absorption migration of active carbon, the flying dust enrichment that is mixed with active carbon that produces the dioxin of high concentration, harm to environment is very big, the at present disposal for the castoff burning flying dust does not have good way yet, the method of domestic main landfill is disposed this class flying dust, and is very big to the potential hazard of environment; The 2nd, this method need to consume a large amount of active carbons, and operating cost is comparatively outstanding.
Adding the sulphur inhibitor is proved to be and can reduces synthesizing of dioxin in the source, main application form is rubbish and coal multifuel combustion at present, but the main purpose of coal multifuel combustion is because the calorific value of rubbish own is lower, need auxiliary fuel could burn thoroughly, relative higher sulfur content has also played the inhibitory action of dioxin in the coal.But along with the raising of economic level, the calorific value in the rubbish also increases gradually now, and will not need coal as auxiliary fuel future.And for the disposable small incinerator of some heats, coal is uneconomic especially.Can predict the inhibitor such as following separately interpolation sulphur, urea will be the principal mode of commercial Application.
Sulphur inhibitor such as sulfur dioxide itself commonly used are exactly pollutant, need special purifier to prevent from emitting environment to be worked the mischief, and substantially can not reuse after the purification, and operating cost is higher.
